CHAPTER 9
THE FEEL BETTER FAST DIET
FOODS THAT HELP YOU FEEL GREAT NOW AND LATER
The real “weapons of mass destruction” are highly processed, pesticide-sprayed, high-glycemic, low-fiber foodlike substances in plastic containers.
MEMORY RESCUE
With the help of my wife and coworker, I traded the fast food for more nutritious options. At first I was very fearful that I wouldn’t be satisfied, or that my cravings would just drive me back to the same old foods and huge portions. But something amazing happened —my cravings disappeared virtually OVERNIGHT. I had no idea that nutritious foods could be so satisfying! It’s like someone flipped a switch in my brain!
RICK, WHO LOST 100 POUNDS IN A YEAR AND HAS KEPT IT OFF FOR FIVE YEARS
Victor, 53, had suffered with anxiety, depression, and insomnia for decades. He had seen endocrinologists, psychiatrists, cardiologists, and sleep doctors with no relief. He had tried multiple medications after a suicide attempt, but none of them had helped.
One of the strategies we commonly use at Amen Clinics is to change our patients’ diets. We help them eat foods that nourish their brains and bodies —such as colorful vegetables and fruits as well as healthy proteins and fats —and eliminate, at least temporarily, all of the potential troublemaker foods that could be causing negative reactions in their bodies, such as gluten, dairy, corn, soy, food additives and preservatives, and artificial sweeteners. I first heard of this idea more than 25 years ago from my friend Dr. Doris Rapp, who saw remarkable improvements in children with ADHD, aggression, and even autism when they eliminated these foods. Subsequently, I have read a growing number of studies in journals, such as the Lancet, reporting significant benefits from dietary interventions.[251] Some of our patients resist —remember, the brain hates change —but we reassure them that when this strategy is conscientiously applied, it can be more effective than almost anything else they could do for their health.
In medical school, like most of my colleagues, I received minimal nutrition education, equivalent to two days out of the 140 weeks it takes to get a medical degree. This state of affairs is insane given that 75 percent of the health care dollars in the United States are spent on chronic, preventable illnesses[252] that stem from our diet and lifestyle choices. Research suggests that our poor choices account for 90 percent of type 2 diabetes, 80 percent of coronary artery disease, 70 percent of strokes, and 70 percent of colon cancer.[253] Poor diets are also associated with depression,[254] anxiety,[255] ADHD,[256] dementia,[257] and even suicide.[258] But there is good news: Brain-healthy diets have been shown to be effective treatments for depression,[259] ADHD,[260] and cognitive decline.[261]
When I first attended Alcoholics Anonymous (AA) meetings as part of my psychiatric training, I was dismayed to see that many recovering alcoholics continued to smoke cigarettes, drink loads of coffee filled with fake creamers and sugar, and eat donuts and other unhealthy foods. In their attempts to get better, they were perpetuating inflammation and making themselves worse. Even today, when I speak at churches, schools, hospitals, addiction treatment centers, and businesses —places that are supposed to be serving the health of others —I’m routinely horrified by the food that’s served, which is toxic to brain health.
Victor, whose story I opened with, was a vegetarian, which put him at a higher risk of depression,[262] and his diet consisted mostly of beans, rice, corn, and cheese. He told our nutritionist he was willing to try a healthier diet and gave up gluten, dairy, corn, and all the other potential problem foods mentioned earlier. As I wrote in Memory Rescue, after a week on the new eating plan, his mood was better than it had been in years. Then he added back each of the foods, one at a time. He added back gluten, and nothing happened. The same was true of dairy, except he had more gas and a queasy stomach, and of soy. But when he added back corn, he said he knew “within a couple of bites” that it was the problem. He had an image of putting a gun in his mouth and pulling the trigger, something that had not happened since before he went on the diet. Even though Victor loved corn chips, corn tortillas, and popcorn, they obviously did not love him back. He decided that this bad relationship was not worth the pain, so he kicked corn out of his life. He was shocked that after suffering for so long he could feel normal with so little effort. You can too —by eliminating foods that are potentially harmful for you and only eating those that serve your health.
Food can be medicine or poison. Intuitively, most people know that certain foods affect their energy and moods. Having a big plate of pasta at lunch, for example, causes a blood sugar spike that makes you feel great for a short while. But it also stimulates your pancreas to produce lots of insulin, which will ultimately make your blood sugar fall so you feel tired and lethargic, as if your mind were swimming in mud.
This chapter will give you a dietary plan in five straightforward strategies to help you feel better fast.
THE FEEL BETTER FAST DIET: FIVE SIMPLE STRATEGIES
- Give yourself an attitude makeover.
- Learn the Feel Better Fast food rules.
- Time your meals to get healthier.
- Choose 20 foods you love that love you back.
- Know which foods to lose and which to choose to help attention, energy, mood, memory, anxiety, pain, and sleep.
Strategy #1: Give yourself an attitude makeover.
Your attitude, or mind-set, may be the single most important factor in feeling better fast. When your mind-set is one of deprivation and your focus is on what you cannot have, you are more likely to remain mired in illness and brain fog. Yes, you may be giving up sugary fast foods and beverages you enjoy —which are often, by the way, pesticide-laden —but these are the very things that drive inflammation and illnesses such as diabetes, heart disease, cancer, depression, dementia, and early death. To feel better fast and make it last for a lifetime, it is critical to develop an abundance mind-set, where you focus on the high-quality, nutritious, and delicious foods you can have that build and sustain your health. If you are able to change your attitude about this, everything else will be easier.
Think for a moment about the advertising slogans that swirl on the airwaves and Internet and on food packaging, targeted at you and your children:
- “I’m lovin’ it”
- “It’s finger lickin’ good!”
- “Have it your way”
- “Open happiness”
- “You deserve a break today”
- “Oh, I wish I were an Oscar Mayer wiener . . .”
- “They’re gr-r-reat!”
- “They’re magically delicious!”
- “The Breakfast of Champions”
- “Melts in your mouth, not in your hand”
- “Betcha can’t eat just one”
Big business has purposefully designed these catchy jingles and phrases to target your mind and trigger the “bliss point” in your brain. Yes, you are being brainwashed. In the 1970s, Howard Moskowitz, a mathematician, discovered the perfect combination of sugar, salt, and fat that would optimize the human brain’s pleasure experience —what he dubbed the “bliss point.” Triggering it not only increases sensory experiences like taste and texture but activates the nucleus accumbens and other centers deep in the brain that are associated with motivation and pleasure. As discussed in chapter 8 (see page 183), the nucleus accumbens is the same part of the brain that is activated by certain drugs, such as cocaine, methamphetamines, nicotine, and morphine. In other words, the job of food designers is to create foods that hook your brain, just as addictive drugs do. “Betcha can’t eat just one”! They were not kidding.
Here are a few of the weapons food scientists have discovered or manipulated to hook your brain:
- Vanishing caloric density or “meltiness”: Foods that melt quickly make the brain think there are fewer calories; hence you eat more.
- Sensory-specific satiety: This refers to our tendency to become bored with eating the same food multiple times. Researchers discovered how to override the brain signal behind it by not including one distinct, overwhelming flavor. (Cooking with a variety of healthy herbs and spices does the same thing, only in a healthy way.)
- Perfect crunchiness: The perfect break point for this pleasure signal is four pounds of pressure.
- Texture: Removing fiber helps food slide down the throat more easily and increases the pleasure sensation. Fiberless food also means you can eat your food more quickly and get out of the fast food restaurant in less time, meaning these food emporiums can serve more bodies in a single day.
- Aroma: Flavor is enhanced by aroma. In fact, humans have only five major taste sensations —sweet, sour, bitter, salty, and umami, or savory, as in meat broth or tomato sauce. Other nuances are created through smell. That’s why Cinnabon, for example, places ovens at the front of its stores and bakes fresh rolls every 30 minutes on a schedule. Between times, the chain eatery often bakes brown sugar and cinnamon just to create the enticing aroma that patrons seem helpless to resist.
- Sugar: In animal and human studies, sugar has been found to be an addictive substance that prompts bingeing, reward-seeking, craving, and tolerance (it takes more and more to get the same response).[263]
Society and corporations blame you for being overweight or sick because you lack self-control and portion control, or because your level of exercise is inadequate. But how can you have self-control when food scientists have been using sophisticated neuroscience and plotting against your brain for decades?
The first step in reorienting your eating habits is to stop being a victim of the food companies and start taking control of the food you put in your body. Start by changing your attitude. Why do I buy only healthy food for my family and team members at Amen Clinics? These are behaviors that help fuel success in every area of our lives. Plus, I love my family, the people I work with, and myself. Doing the right things for our health is never about deprivation; it is always about the abundance of what we really want —happiness, mental clarity, energy, effectiveness, and longevity. Why should you be serious about the quality of the nutrients you put in your body and the bodies of those you care about? Because doing so gives all of you the best chances at feeling great now and later, and because you love your friends, your family, and yourself. It’s really that simple. Making consistently good decisions about food is an act of love. Damaging your most precious assets (brain and body) with poor-quality foodlike substances is an act of pure sabotage toward yourself and others.
Over the years, many people have told me this position is extreme and I should lighten up. Their reasoning includes responses like these:
- “It’s best to practice moderation.” I believe this is usually an excuse or rationalization to make poor decisions.
- “Relax! We are all dying, so why not have a little fun along the way?” Yes, we are all dying, but why accelerate it? Doesn’t the quality of your life, now and into the future, matter? This response also reveals a lack of understanding that high-quality food can taste amazing.
- “I can’t afford to eat healthy.” In truth, you can’t afford not to eat healthy. Consuming low-quality, cheap food ends up being far more expensive in the long run in terms of elevated health care costs and poor decision-making. According to the Harvard School of Public Health, eating healthy costs about an extra $1.50 a day.[264] You can make that up with one less coffee run.
- “I don’t have time.” Sure, grabbing a donut or ordering take-out burritos or deep-fried wings provides a speedy meal, but it’s just as fast to grab an apple or orange or to order take-out salad bowls —and they will help you feel better fast and stay healthier. It takes some planning to eat food that is good for you, but meal kits from AmazonFresh, Walmart (Takeout Kit and Home Chef), and others can help without breaking your budget or requiring a lot of time.
- “It’s too hard.” Being disciplined about eating is not the easiest habit to incorporate in a world of toxic choices, but it’s worth the effort. Think of it this way: Whatever you are doing now is a habit, and you can develop new habits that serve your health rather than steal from it.
- “Why be so radical?” I am convinced we need to be more serious now than ever. Low-quality diets are clearly associated with poor school performance in childhood and dementia in the elderly, and virtually every illness in between, including depression, diabetes, heart disease, cancer, autoimmune diseases, and obesity. My wife, Tana, and I wrote about this in The Brain Warrior’s Way, detailing how you are literally in a war for the health of your brain. Everywhere you go, someone is trying to entice you to swallow unhealthy food that can lead to an early death.
Research is uncovering ever more reasons for urgency. In a recent study in mice at the University of Bonn, scientists found that a high-fat, high-calorie Western diet appears to make the immune system react as it would to a bacterial infection. This diet made the mice’s immune systems more aggressive over the long run, and even after the animals were put on a healthy eating plan, their bodies responded with greater inflammation —a response that may be linked to the development of type 2 diabetes and clogged arteries.[265] All this research can provide motivation for us to make over our attitudes and develop a positive mind-set toward healthy eating.
Strategy #2: Learn the Feel Better Fast food rules.
There are nine rules, or guidelines, that will help you start to eat healthier. You may already be following some of these guidelines —if so, good for you! The more of them you adopt, the better off your brain and body will be.
CONCENTRATE ON CONSUMING BRAIN-SMART CALORIES
Calories do matter. If you eat more of them than you burn, you will definitely gain weight, and as discussed in the introduction (see page xxv), as your weight goes up, the size and function of your brain go down. Yet the quality of your calories matters more than the amount. Contrast a 582-calorie meal of a large soda and a slice of pizza, which promotes inflammation, brain fog, and illness, with a 540-calorie meal of wild salmon, Swiss chard, sweet potato, and dark chocolate, which promotes good health. Your brain will be sick on the first regimen and healthier on the second. If you struggle with your weight, focusing on quality, not quantity, may also lead you to consume fewer calories and shed pounds: A recent study of 600 people led by the Stanford Prevention Research Center found that those who focused on eating healthier foods without worrying about cutting calories lost significant amounts of weight and improved on a number of health measures, including waist size and blood sugar and blood pressure levels.[266]
I am a value spender. Even though I have enough money, I hate wasting it. I think of calories like money and hate wasting them as well. Focus on foods that are nutritious, delicious, and calorie smart.
MAKE (ZERO-CALORIE) WATER YOUR BEVERAGE OF CHOICE
Your brain is 80 percent water. Being dehydrated by just 2 percent impairs your ability to carry out tasks that require attention, memory, and physical performance.[267] I recommend drinking about eight 10-ounce glasses of water a day. If you drink a glass of water 30 minutes before meals or snacks, you’re likely to eat less and still feel satiated. However, avoid drinking water with your meal, as it slows down digestion by diluting stomach acid. And try to limit consumption of anything that dehydrates you, including caffeine, alcohol, and other diuretics.
Just as critical is that you avoid drinking your calories. Replace sodas (including diet sodas —see the section on artificial sweeteners on page 214), fruit juices, and other sugary drinks with water. Drinking just one can of sweetened soda or fruit punch a day can result in a weight gain of up to five pounds in one year! No wonder so many Americans are always on a diet.
EAT SMALL AMOUNTS OF PROTEIN SEVERAL TIMES A DAY
Think of protein the way you do medicine —that it should be taken in small doses with every meal and snack. Protein helps to balance blood sugar levels, decrease cravings, and burn more calories than eating high-carb, sugar-filled foods. Protein also provides your body with the amino acids it requires. Nuts, seeds, legumes, some grains, and vegetables contain some of the 20 essential amino acids you need. Fish, poultry, and most meats contain all of them. To the degree your budget allows, shop for animal protein that is free of hormones and antibiotics, free-range, and grass fed. It is more expensive than industrial, farm-raised animal protein, but it is a good investment in your health. Be careful not to overdo it on protein, as that can put an increased strain on your kidneys and promote inflammation. Somewhere in the range of 15 to 25 percent of your total daily calories is a healthy amount.
MAKE FRIENDS WITH FAT
Fat continues to get a bad rap, despite the fact that good fats are essential to the health of your brain and do not raise your cholesterol. In fact, low-fat diets are bad for the brain. A Mayo Clinic study found that people who ate either a fat-based or a protein-based diet had a 42 percent or a 21 percent lower risk, respectively, of developing mild cognitive impairment and dementia, but those who ate a diet based on simple carbohydrates (think bread, pasta, potatoes, rice, and sugar) had a 400 percent increased risk of developing these conditions.[268] Fat is not the problem —sugar is.
In a powerful new study from multiple highly regarded institutions around the world, researchers followed more than 135,000 people from 18 countries for an average of 7.4 years. They found that those who consumed the highest amount of dietary fat, including saturated fat, had a 23 percent reduced risk of death, while those who ate the highest amount of carbohydrates had a 28 percent increased risk of death. Higher consumption of saturated fat was surprisingly associated with a lower risk of stroke. The researchers concluded, “High carbohydrate intake was associated with higher risk of total mortality, whereas total fat and individual types of fat were related to lower total mortality. Total fat and types of fat were not associated with cardiovascular disease, myocardial infarction, or cardiovascular disease mortality.”[269]
While it’s smart to avoid fried fats, trans fats, and some saturated fats, cutting way back on healthy fats is harmful, because your body needs them for many crucial functions. Here’s a brief look at how different kinds of fats impact health:
- Unsaturated fats. These are good fats because they contribute to heart and brain health. There are two kinds of unsaturated fats: polyunsaturated and monounsaturated. Two important polyunsaturated fats are
- Omega-3 fatty acids. EPA and DHA, two omega-3s, are crucial for optimal brain health and are found in cold-water fish, such as salmon, tuna, and sardines. Deficiencies in these fatty acids have been associated with cognitive decline, depression, and many other illnesses. Higher levels of the omega-3 fatty acids EPA and DHA have been associated with a lower incidence of Alzheimer’s disease and slower cognitive decline.[270]
- Omega-6 fatty acids. These are also necessary for good health, but they can be harmful when eaten in excess. Omega-6 fatty acids are found in most vegetable oils (soybean, sunflower, safflower, corn, and canola), as well as many fried foods, cereals, whole-grain breads, and processed foods —all common in what we call the standard American diet. Most people who eat this diet have an unhealthy ratio of omega-6 to omega-3 fatty acids —20 to 1 or higher —which is pro-inflammatory and increases the risk of heart disease, cancer, diabetes, and a host of other health problems. The optimal omega-6 to omega-3 ratio in your blood is likely under 4 to 1.
The best way to balance your omega-6 to omega-3 ratio is to eat fewer foods that contain omega-6s and more that contain omega-3 EPA and DHA. Certain plant foods, including flaxseeds and green leafy vegetables, contain alpha-linoleic acid (ALA), an omega-3 fatty acid that some people can convert in small amounts to EPA/DHA. However, you can’t rely on it as your only source of omega-3s; taking fish-oil supplements can help ensure healthy levels.
- Saturated fats. Saturated fats tend to be less healthy than unsaturated fats, but they differ depending on their chemical makeup. Short- to medium-chain saturated fats (those with 4–12 carbons) are healthier than longer-chain ones, according to cardiologist Mark Houston of Vanderbilt University.[271] Here are a few examples of potentially healthier and unhealthier saturated fats; check food labels for them:
- Butyric (4-carbon) acid is found in fiber-rich foods (sweet potatoes, vegetables, beans, nuts, and fruit), butter, and ghee.
- Caprylic (8-carbon), capric (10-carbon), and lauric (12-carbon) acids are medium-chain fatty acids found in coconut.
- Myristic acid is a 14-carbon saturated fat found in most animal fats and some vegetable oils. There is some evidence that this fatty acid can be detrimental to heart health and should be consumed only in small amounts.
- Palmitic acid is a 16-carbon, long-chain saturated fat that creates the marbling in corn-fed beef. It has a negative impact on cholesterol and heart health.
- Stearic acid is an 18-carbon, long-chain fatty acid found in grain-fed meats, sausage, bacon, cold cuts, peanuts, peanut butter, margarines, fried potatoes, whole milk, cheeses, and vegetable oils (sunflower oil has the most). Chocolate is high in stearic acid but also high in antioxidants and flavonoids, which help to balance its health benefit.
The healthiest dietary strategy is to cut back on certain types of saturated fats (especially myristic, palmitic, and stearic acids) and increase consumption of polyunsaturated fatty acids found in fish oil, nuts, and seeds.
- Trans fats. These synthetic fats are found in partially hydrogenated vegetable oils, and they have no place in anyone’s diet.[272] They decrease healthy blood flow and increase the likelihood of blood clots, which can cause strokes and heart disease. They are found in shortening and many processed foods, margarines, commercially prepared fried foods, and packaged baked goods, including donuts, crackers, and snack foods. When a packaged-food label reads “trans fat–free,” it may be a lie. Regulations do not require that trans fats be listed on a food label if the level is below the legal limit of 0.5 grams per serving. For many baked goods and pastries that are in excess of five ounces —a single pastry is often labeled as several servings, even though most people eat it as one serving —that can translate to two or three grams of trans fat. Even small amounts of these very unhealthy fats should be avoided. Fortunately, the FDA has banned trans fats in processed foods; the ban went into effect in June 2018 for the great majority of foods.
CHOOSE HEALTHY (HIGH-FIBER, BLOOD-SUGAR-STEADYING) CARBOHYDRATES
So-called “smart” carbohydrates are essential to life because they are loaded with nutrients, help to balance your blood sugar, and decrease cravings. Most vegetables, legumes, and fruits, such as apples, pears, and berries, that are low glycemic (unlikely to raise blood sugar) are smart carbs. High-glycemic, low-fiber carbohydrates steal your health because they promote inflammation, diabetes, and depression.[273] Examples include sugar and foods that quickly turn to sugar, such as bread, rice, pasta, and white potatoes.
Fiber is a special type of carbohydrate that enhances digestion, reduces the risk of colon cancer, and helps to balance blood pressure and blood sugar. The average American consumes far too little —less than 15 grams of fiber daily. Women should consume 25–30 grams of fiber every day; men, 30–38 grams. High-fiber foods, such as broccoli, berries, onions, flaxseeds, nuts, green beans, cauliflower, celery, and sweet potatoes (the skin of one sweet potato has more fiber than a bowl of oatmeal!) have the added benefit of making you feel full faster and longer.
FILL YOUR PLATE WITH COLORFUL VEGETABLES AND FRUITS
Colorful vegetables and fruits have tremendous health benefits. They provide an enormous array of the plant nutrients, vitamins, minerals, and antioxidants that are necessary for good health. Plant foods also help prevent cancer and reduce inflammation, which contributes to Alzheimer’s disease, heart disease, arthritis, gastrointestinal disorders, high blood pressure, and many other illnesses. A 2016 study found a linear correlation between the number of fruits and vegetables you eat and your level of happiness.[274] The more colorful fruits and vegetables you eat —up to eight servings a day —the happier you become, and it happens almost immediately. No antidepressant works this fast! Just stick with a two-to-one ratio of vegetables to fruits to limit sugar.
ADD BRAIN-HEALTHY FLAVOR WITH HERBS AND SPICES
Food seasonings contain so many health-promoting substances that it almost makes sense to store them in the medicine cabinet rather than the spice cupboard! Here are some of the most powerful of these herb and spice brain boosters.
- Basil
- Black pepper
- Cayenne pepper
- Cinnamon
- Cloves
- Garlic
- Ginger
- Marjoram
- Mint
- Nutmeg
- Oregano
- Parsley
- Rosemary
- Saffron
- Sage
- Thyme
- Turmeric (curcumins)
AVOID OR ELIMINATE FOODS THAT CAN POTENTIALLY HURT YOU
Some foods are not worth the downsides that come along with them. The following are several to limit or avoid altogether if you want to keep your brain healthy. If you struggle with mood issues, anxiety, temper problems, or learning challenges, eliminate all of the foods listed for at least a month. Then, once all of them are out of your system, add back one each week and see which, if any, may be causing you trouble. This process may make an amazing difference in your health. While I believe everyone would benefit from eliminating these foods permanently, I know not everyone may choose to do that. Most people are willing to start with the elimination diet. When they see how much better they feel off these foods, many will make permanent changes.
- Sugar. Americans eat about 140 pounds of sugar a year. Refined sugar is 99.4 to 99.7 percent pure calories, with no vitamins or minerals —just carbohydrates. Sugar is addictive, interferes with the actions of calcium and magnesium, increases inflammation and erratic brain-cell firing, and has been implicated in aggression. Sugar consumption has been associated with brain fog, depression, ADHD, increased triglycerides and “bad” LDL cholesterol, and lower “good” HDL cholesterol. In brain imaging studies, sugar increases slow brain waves (associated with memory problems), and a study at UCLA showed that sugar negatively alters learning and memory.[275] Avoid agave, too, because of its high fructose content.
- Artificial sweeteners. Consuming sugar alternatives can contribute to chronically high insulin levels, which increases your risk for Alzheimer’s disease, heart disease, diabetes, metabolic syndrome, and other health problems. Artificial sweeteners do not help you lose weight. In fact, they may lower metabolism, leading to weight gain. Avoid aspartame (NutraSweet, Equal), saccharin (Sweet’N Low), and sucralose (Splenda). If you want something sweet, use small amounts of erythritol or stevia.
- Gluten. This sticky substance is found in wheat, barley, rye, kamut, bulgur, and spelt, and in most commercially made breads, cakes, cookies, cereals, and pasta. It is also hidden in everything from salad dressings and sauces to processed foods and cosmetics. Gluten-related health issues are on the rise, including celiac disease, type 1 diabetes, and Hashimoto’s thyroid disease —all of which are autoimmune conditions. Gluten can also trigger psychological disturbances, skin rashes, acne, inflammation, alopecia (baldness), arthritis, and food addiction. In one study, putting celiac patients on a gluten-free diet significantly decreased anxiety.[276] Gluten can also reduce brain blood flow.[277] There’s no healthy reason to eat it.
- Soy. Soy (found in tofu, edamame, and soy sauce and also added to a huge range of foods) contains large amounts of omega-6 fatty acids, phytoestrogens (which may contribute to the development of cancer, early puberty in girls, and impotence in men), and phytic acid, which is thought to reduce the absorption of vital minerals.
- Corn. Why do farmers feed animals corn, soy, and potatoes? To make them fat! Corn is high in omega-6s and very low in omega-3s, making it pro-inflammatory. Corn has been shown to damage the intestinal lining and create leaky gut. Most of the corn in the US is sprayed with the glyphosate pesticide Roundup, which has been associated with cancer, depression, Parkinson’s disease, MS, hypothyroidism, and liver disease.[278]
- Dairy. Cow’s milk is perfect for calves but unnecessary for humans. After the age of two, fewer than 35 percent of humans produce the enzyme lactase, which is needed to break down lactose (milk sugar) and digest milk. Lactose is converted to galactose and glucose, which elevates blood sugar and can cause inflammation. Casein, one of the proteins in dairy, is an excitotoxin. Left unchecked, excitotoxins lead to brain inflammation and neurodegenerative diseases. In several studies, a link has been suggested between milk drinking and Parkinson’s disease.[279] Most dairy cattle are given antibiotics and hormones, which can also end up in your body. Unsweetened almond milk is a good substitute for cow’s milk.
CHOOSE ORGANIC, TOXIN-FREE FOODS WHENEVER POSSIBLE
Fast food, sugar, simple carbohydrates, dairy products, trans fats, excess omega-6 fatty acids, and foods that are processed, engineered, or refined promote chronic inflammation. These are the foods that the standard American or Western diet is built upon. That’s why it’s so important, whenever possible, to shop for organically grown or raised foods, which are free of hormones, antibiotics, and chemicals. Try to eliminate food additives and artificial preservatives, dyes, and sweeteners, too, and look for meat that is grass fed.
Fish is a great source of healthy protein and fat, but some varieties tend to have more toxins. The larger the fish, the more mercury it may contain, so it’s best to eat mostly smaller varieties and have the larger ones (like tuna) less frequently. Eat a fairly wide variety of fish, preferably those highest in omega-3s, like wild Alaskan salmon, sardines, anchovies, hake, and haddock. Learn more at www.seafoodwatch.org.
I understand that many people cannot afford to buy only organic and sustainably raised food. That is why I recommend consulting the Environmental Working Group’s annual lists of produce with the highest and lowest levels of pesticide residues to help inform your choices. (Stay updated at www.ewg.org.)
Strategy #3: Time your meals to get healthier.
If you have symptoms of low blood sugar, getting your diet right can make an immediate positive difference for you. I had a patient who was arrested multiple times for angry outbursts, but in my office, he was typically one of our sweetest patients. One day he came to see me, sweating profusely, and he was angry and inappropriate with our office staff. Suspecting low blood sugar, I ordered a glucose tolerance test. We measured his blood glucose level at baseline and again 30 minutes and two hours after he drank the equivalent of sugar water. His two-hour blood glucose level was dangerously low. When the brain does not get enough glucose, watch out!
If you suspect you suffer from low blood sugar levels, make a practice of eating four to five meals a day that combine protein, fat, and smart carbohydrates to help steady your blood sugar.
If you do not have hypoglycemia, “intermittent fasting” or “time-restricted feeding” can significantly improve memory,[280] mood,[281] fat loss,[282] weight, blood pressure, and inflammatory markers.[283] Nightly 12-to-16-hour fasts turn on a process called autophagy, which helps your brain take out the trash it accumulates during the day.[284] This can help you think more clearly and feel more energetic, and it’s simple —if you eat dinner at 6 p.m., don’t eat again until 6–10 a.m. the next day. Your brain will have the time it needs to cleanse itself.
Not eating within two to three hours of bedtime also reduces your risk of heart attack and stroke.[285] In healthy people, blood pressure drops by at least 10 percent when they go to sleep, but blood pressure in late-night eaters stays high, increasing the risk of vascular problems. Also, new research suggests that if you have more calories at lunch and then eat a light dinner, you are more likely to lose weight than the other way around.[286]
Strategy #4: Choose 20 foods you love that love you back.
To be successful at optimizing your diet, you must find foods you love that love you back. As I detailed in chapter 4 (see page 69), we are creatures of habit and change can be hard. That is why you have to set yourself up to win. Do this by finding 20 high-quality, delicious foods and beverages, based on the rules outlined above. If you can find 20 foods, odds are you will be able to find 40, 80, 100, or more. To give you a head start, here is a list of 162 of my favorite Feel Better Fast Brain-Healthy Foods and Beverages that comply with our food rules. Some of these items may be new to you, but you can research them more online or ask your grocer where to find them.

I don’t know about you, but I’ve been in bad relationships in the past. I’m so thankful now that I have a partner and wife who is good for me and loves me in return for my love. Choosing healthy food is so much easier than finding the right life partner! I am committed to only eating and loving food that is good for me and loves me back.
Strategy #5: Know which foods to lose and which to choose to help attention, energy, mood, memory, anxiety, pain, and sleep.
When you are feeling low, there are nutrients you should lose and others you should choose that will help you feel better fast. Following the general “Foods to Lose” list are diagrams and lists of food choices that will improve your attention and energy, moods, memory, and sleep and will reduce anxiety and pain.
FOODS TO LOSE: THESE MAKE YOU FEEL GOOD NOW BUT NOT LATER
- Pro-inflammatory foods, such as fast food (pizza, donuts, French fries, ice cream), sugar, simple carbohydrates, refined grains, wheat flour, dairy products, and omega-6 fatty acids (found in grain-fed meats, corn, soybeans, and vegetable oils —corn, safflower, sunflower, soybean, canola, and cottonseed)
- Trans fats —avoid anything with “partially hydrogenated” or “vegetable shortening” on the label
- Processed meats —sodium nitrites can combine with amines to form nitrosamines, which are carcinogenic
- Food additives, such as MSG and aspartame
- Anything that disrupts the gut lining, such as gluten
- Alcohol[289]
- Aspartame[290]
- Caffeine[291]
FOODS TO CHOOSE: THESE MAKE YOU FEEL GOOD NOW AND LATER
To Boost Attention/Energy: A higher-protein, lower-carbohydrate diet, especially consumed around the times you need to focus, can be helpful. Consider this diagram:
- Dopamine-rich foods —for focus and motivation: turmeric,[296] green tea (for theanine),[297] lentils, fish, lamb, chicken, turkey, beef, eggs, nuts and seeds (pumpkin and sesame), high-protein veggies (such as broccoli and spinach), and protein powders
- Beets —increase blood flow to the brain
- Celery[298]
- Flavonoid-containing foods —blueberries, strawberries, raspberries, cocoa[299]
- Green tea[300]
- Green leafy vegetables
- Omega-3-rich foods —flaxseeds, walnuts, salmon, sardines, beef, shrimp, walnut oil, chia seeds, avocados, and avocado oil
- Spices —peppermint,[301] cinnamon,[302] and rosemary
- Water
To Boost Mood: Foods that raise serotonin can be helpful. Consider this diagram:
- Serotonin-rich foods —combine tryptophan-containing foods, such as eggs, turkey, seafood, chickpeas, nuts, and seeds (building block for serotonin), with healthy carbohydrates, such as sweet potatoes and quinoa, to elicit a short-term insulin response that drives tryptophan into the brain. Dark chocolate[303] also increases serotonin.
- Limit simple carbohydrates, such as bread, pasta, potatoes, and rice, as they may help you feel good in the short run but increase inflammation and illness in the long run.
- Prebiotic-rich foods —see “Feel Better Fast Brain-Healthy Foods and Beverages,” on page 219.
- Probiotic-rich foods[304] —see “Feel Better Fast Brain-Healthy Foods and Beverages,” on page 220.
- Spices —saffron,[305] turmeric (curcumins),[306] and saffron plus curcumins[307]
- Fruits and vegetables —eat up to eight servings a day[308] to feel happier.
- Maca —this root vegetable and medicinal plant, native to Peru, has been shown to reduce depression.[309]
- Omega-3-rich foods —see “To Boost Attention/Energy” on page 224.
To Boost Memory: The Western, pro-inflammatory diet is associated with a smaller hippocampus and cognitive impairment.[310] A new way of eating for Americans is essential if we want to keep our brains healthy. Consider this diagram:
- Antioxidant-rich foods —acai fruit, parsley, cocoa powder, raspberries, walnuts, blueberries, artichokes, cranberries, kidney beans, blackberries, pomegranates, chocolate, olive and hemp oils (not for cooking at high temperatures), dandelion greens, and green tea
- Chocolate (cocoa flavonols)[311]
- Choline-rich foods —to support acetylcholine and memory:[312] shrimp, eggs, tofu, scallops, chicken, turkey, beef, cod, salmon, shiitake mushrooms, chickpeas, lentils, and collard greens
- Omega-3-rich foods —see “To Boost Attention/Energy” on page 224.
To Reduce Anxiety: Low blood sugar states are often associated with anxiety. Being “hangry” (irritable from extended periods without eating) and being anxious often go together.
- Gamma-aminobutyric acid (GABA)–rich foods —for antianxiety: broccoli, almonds, walnuts, lentils, bananas, beef liver, brown rice, halibut, gluten-free whole oats, oranges, rice bran, and spinach
- Green tea, which contains L-theanine, an ingredient that helps you feel happier, more relaxed, and more focused[313]
- Magnesium-rich foods —pumpkin and sunflower seeds, almonds, spinach, Swiss chard, sesame seeds, beet greens, summer squash, quinoa, black beans, and cashews
- Omega-3-rich foods[314] —see “To Boost Attention/Energy” on page 224.
- Probiotic-rich foods —see “To Boost Mood” on page 225.
To Reduce Pain:
- Omega-3-rich foods —see “To Boost Attention/Energy” on page 224.
- Serotonin-rich foods —see “To Boost Mood” on page 225.
To Boost Sleep:
- Magnesium-rich foods —see “To Reduce Anxiety” on page 226.
- Serotonin-rich foods —see “To Boost Mood” on page 225.

TINY HABITS THAT CAN HELP YOU FEEL BETTER FAST—AND LEAD TO BIG CHANGES
Each of these habits takes just a few minutes. They are anchored to something you do (or think or feel) so that they are more likely to become automatic. Once you do the behaviors you want, find a way to make yourself feel good about them—draw a happy face, pump your fist, or do whatever feels natural. Emotion helps the brain to remember.
- When I am tempted by French fries, sugary treats, or soda, I will resist and say to myself, “I only love foods that love me back.”
- Before I leave the house, I will put a full water bottle inside my purse or computer bag.
- When I prepare my food shopping list, I will include fish and vegetables.
- When I finish dinner, I will note the time and make plans to eat my next meal at least 12 hours later to give my brain time for waste removal.
- When I pick up a new item at the grocery store, I will read the food label.
- When I’m in a low mood, I will eat a piece of low-sugar or sugar-free dark chocolate to boost my serotonin level.
- When I eat a food I love that loves me back, I will note it down in my “favorite healthy foods” list.
- When the waiter comes for my order at a restaurant, I will say, “Please don’t bring bread to the table.” Making that one decision will help me make healthier choices throughout the meal.
- When I go food shopping, I will look for organic fruits and vegetables first.
