CHAPTER 16

THE MEMORY RESCUE DIET

FOOD FOR BRIGHT MINDS

I visited one of the big box stores for the first time ever this weekend. There was death everywhere (the toxic food), around every corner. Samples of death covered in death. I just kept hearing Dr. Amen in the back of my mind. So I walked past it all! Got my organic goods and left, which is saying a lot because it was nearly lunchtime and it all smelled so good! Thank you for giving me the tools to make good choices.

FROM A PARTICIPANT IN THE BRAIN WARRIOR’S WAY LIVE CLASS

To rescue your memory, choosing the right foods is one of the most important strategies of all. Your brain uses 20 to 30 percent of the calories you consume. It is the most energy-hungry organ in your body. If you eat a fast-food diet, you will have a fast-food mind that is less capable of quick thinking and reliable decision making.

The prescriptions at the end of every chapter in part 2 include lists of foods shown to have particular benefit in reducing the various risk factors. In this chapter I want to introduce you to a diet that everyone should follow if they want to protect their memory. Once you commit to the brain-healthy diet I discuss, you will quickly notice that you have more energy; fewer cravings; better focus, memory, and moods; and even a flatter stomach within a matter of weeks.

A number of recent studies report that a healthy diet, like the Memory Rescue Diet, is associated with significantly lower risks of severe memory problems such as Alzheimer’s disease, as well as most of the risk factors I’ve discussed, including heart disease, inflammation, depression, and diabesity.[570] Healthy diets are also associated with bigger brain size.[571] And bigger is better when it comes to the brain.

THE MEMORY RESCUE DIET CHECKLIST

Over the past three decades I have developed a new approach to diet that focuses on changing the way you think about eating as well as the way you actually eat. These two principles form the backbone of the Memory Rescue Diet, and the checklist below provides the specific components of this brain-healthy approach to eating. They are designed to guide you to make the best food choices for your brain for the rest of your life.

  1. Change the Way You Think about Eating
    • Get your mind right. Being healthy is about abundance, not deprivation.
    • Think of calories like money; spend them wisely.
    • Beware the standard American diet (SAD).
  2. Change the Way You Eat (and Drink)
    • Pick the healthiest protein.
    • Get your fill of the right fats.
    • Go for the greens (and reds, yellows, blues, and other hues).
    • Choose brain-boosting carbohydrates.
    • Say good-bye to sugar.
    • Hydrate with H2O.
    • Flavor your food with smart herbs and spices.

As you adopt these healthy eating habits, you will begin developing a new, healthy relationship with food. Contrary to what you might think, eating in a brain-healthy way is not more expensive. It is less expensive when you consider that your medical bills will be lower and your productivity will go up. And what price can you put on your memory?

In fact, the Memory Rescue Diet includes no gimmicks, and there are no “designer” foods to buy. Plus it is simple. I know you won’t follow a program that is complicated or requires you to eat boring foods for the next 40 years. I wouldn’t —why would anyone else? The recommended foods are delicious, energizing, and healing.

CHANGE THE WAY YOU THINK ABOUT EATING

Get your mind right. Being healthy is about abundance, not deprivation.

Too many patients I’ve seen start with this attitude: “I don’t want to deprive myself. I want what I want when I want it.”

My response is, “Which do you want more? Your health, a great brain, years added to your life, and freedom from dementia . . . or the nightly alcohol and sugar?”

Most people fail in nutrition programs because they focus on what they cannot have, rather than on what they can have. They have a deprivation mind-set. They focus on the loss of the very foods that drive inflammation and hijack their taste buds —empty-calorie foods, sugary foods, fast foods, and pesticide-laden foods.

To rescue your memory, the first thing you must do is get your mind right.

In my experience, as people start down the road to getting well, they begin to miss the Rocky Road ice cream, look longingly at the doughnuts, and feel sad about not being able to eat the chicken fried steak, mashed potatoes, and key lime pie. Yet after about 10 days of eating high-quality food, they realize that their taste buds have come alive and food tastes better than ever.

Getting well is about focusing on an abundance of the right nutrients, which will deprive you of illnesses like diabetes, heart disease, cancer, depression, and dementia. This is a critical shift. Those people who continue to follow the Memory Rescue Diet begin to see many unhealthy foods as weapons of self-destruction and avoid them, just as they would avoid shaking hands with someone who was sneezing and coughing up green gunk.

Think of your relationship with food the way you think about your other relationships. Find foods you love that love you back, and stay away from those that abuse you. Just because you “love” something doesn’t mean it’s good for you. I had a patient tell me she’d rather get Alzheimer’s disease than give up sugar. That is an example of an abusive relationship. She was in love with something that hurt her. Fortunately, over time she ended the toxic relationship and helped her whole family get well.

Also lose the idea that you should be able to eat “everything in moderation.” It is nothing more than the gateway thought to dementia hell. It gives you an excuse to continue down the wrong path, and before long it becomes your justification for unhealthy eating every day.

Think of calories like money; spend them wisely.

Thoughtful, successful people tend to be conscientious with their money; they save for retirement and spend their hard-earned cash wisely. Those who don’t are much more likely to experience financial hardship or to file for bankruptcy. I think of calories the same way. They are incredibly important, and you should spend them carefully. That means using your calories on foods that nourish you, rather than on those that steal from your health.

Make no mistake, the quality of your food matters more than the quantity. Compare a 500-calorie blueberry crumb doughnut to a 500-calorie plate of rainbow trout, broccoli, orange bell peppers, raspberries, and almonds. The doughnut will zap your energy and set off an inflammatory response; the fish meal will power your brain and reduce your risk of accelerated aging. You are likely to gulp down the first in a matter of minutes, sending your blood sugar sky-high and teasing your pleasure centers; the second you enjoy at a leisurely pace, and it helps you feel full longer as well as happier and more emotionally stable.

Calories are like money. If you overspend, your body will eventually become bankrupt. Some calories have better exchange rates than others.

This is not to say that the quantity of calories you take in is unimportant. On the contrary, substantial research, first in animals and now in humans, indicates that a calorie-restricted (CR) diet can help control weight; decrease the risk of heart disease, cancer, and stroke; and trigger mechanisms in the body that increase the production of nerve growth factors, which are helpful to the brain. A 25-year study on rhesus monkeys found that those that ate 30 percent fewer calories than the others not only lived longer, they also had a lower incidence of diabetes and cancer, and their hair, skin, and brains looked younger (less shrinkage in the hippocampus).[572] Eating too many calories causes waste to build up in the body’s cells, making everything look and feel older.

Researchers at Columbia University have found that eating fewer calories may be particularly important for people with the APOE e4 gene.[573] They followed 980 elderly individuals for four years, measuring their daily calories. Compared to people with a low calorie intake, those with the highest calorie intake were 2.3 times more likely to develop Alzheimer’s disease —but only if they also had the APOE e4 gene. In other research on CR, in an ongoing project known as the CALERIE study, volunteers who were normal weight or slightly overweight reduced their calorie intake by 25 percent for two years and had significant decreases in cardiovascular risk factors, including lower blood pressure.[574] 

However, calorie restriction has drawbacks: It is hard to maintain long-term and has been associated with decreased testosterone levels, irritability, and a lower sex drive —so there may not be a good reason to live longer. Scientists have looked at other ways to mimic the benefits of CR without these side effects, including the antidiabetic drug metformin, which lowers high blood sugar levels; exercise; stress management; and improved sleep.

CONSIDER INTERMITTENT FASTING AND THE TIMING OF YOUR MEALS

There may be another way to keep your calorie intake in check. As I have discussed, a possible cause of memory loss is the overproduction of beta amyloid and abnormal tau proteins that damage brain cell circuits. One way your brain eliminates these proteins is through autophagy,[575] a process that’s like having tiny trash collectors cleaning up the toxins. Nightly 12-to-16-hour fasts turn on this process. That means if you eat dinner at 7 p.m. and don’t eat again until between 7 and 11 a.m., you give your brain time for trash cleanup. This “intermittent fasting,” as it is called, can significantly improve memory,[576] mood,[577] fat loss,[578] weight, blood pressure, and inflammatory markers.[579] You can also use this method of eating to reduce your calorie consumption —for example, by skipping breakfast and eating only lunch and dinner two or three days each week.

New research also suggests that you should avoid eating within two to three hours of bedtime and that late-night eating puts you at a higher risk of heart attack, stroke, and diabetes.[580] Eating late puts your brain in a “high alert” stress state, causing your body to release stress hormones when it should be winding down. In healthy people, blood pressure drops by at least 10 percent when they go to sleep, but late-night eaters’ blood pressure stays high. People whose blood pressure does not fall at night are known as “nondippers,” and they have a much higher rate of heart-related death. Research has shown that late eaters are nearly three times more likely to be nondippers. You don’t want to be one of them.

Two things seem certain: Consuming too many calories is bad for your brain and body, and if you are going to put something into your body, you want to be sure you are getting the biggest health bang for the cost.

Beware the standard American diet (SAD).

No one makes a conscious decision to eat foods that trigger inflammation, but that is exactly what most Americans do in consuming the standard American diet of fast food; sugar; simple carbohydrates; dairy products; trans fats; some animal-derived saturated fats; excess omega-6 fatty acids; nutrient-bankrupt refined and processed foods; and products filled with pesticide residues, antibiotics, and hormones. This type of diet is loaded with chemicals that are unnatural to your body, which causes it to respond as if it has been injured. Inflammation is your body and brain’s healing response to that injury. Over time, if your diet doesn’t change, the inflammation can become chronic, and as we’ve seen, that can lead to many health problems. It’s enough to make anyone feel SAD!

Right now, make a commitment to become more aware of and serious about the foods you put in your body. Aim to eat “clean” —foods that are organically grown or raised and free of hormones, antibiotics, and pesticides. (Even small amounts of pesticides can build up in your brain and body over time.) Whenever possible, choose meat from animals that are free range and/or grass fed, and organically grown nuts and seeds. Start reading food labels, and do your best to avoid food additives and artificial preservatives, dyes, and sweeteners.

Fish is an excellent source of healthy protein and omega-3 fats, but some varieties are more toxic than others. Generally, smaller fish contain lower amounts of mercury than larger fish like tuna, so limit your consumption of the latter. Whenever possible, buy species that are not overfished, and eat a fairly wide variety, preferably those highest in omega-3s, like wild Alaskan salmon, trout, sardines, anchovies, and Atlantic and Pacific mackerel. Learn more about which fish to add to your diet at www.seafoodwatch.org, the website of the Monterey Bay Aquarium in Monterey, California.

Organic and sustainably raised produce can be pricey, so it helps to know which fruits and vegetables carry the highest pesticide loads and to buy organic when it matters most. I consult the Environmental Working Group’s annual lists of foods with the highest and lowest levels of pesticide residues and recommend that you do so as well. (Stay updated at www.ewg.org.) Here is the current list of 13 foods with the highest levels of pesticide residue: strawberries, spinach, nectarines, apples, peaches, pears, cherries, grapes, celery, tomatoes, sweet bell peppers, potatoes, and hot peppers. Try to buy organic when purchasing these fruits and vegetables.

The 15 foods with the lowest levels of pesticide residue are sweet corn, avocados, pineapples, cabbage, onions, frozen sweet peas, papayas, asparagus, mangoes, eggplant, honeydew melon, kiwifruit, cantaloupe, cauliflower, and grapefruit. (The EWG notes that because a small amount of sweet corn, papaya, and summer squash sold in the United States comes from genetically modified seeds, if you want to avoid GMOs, buy organic varieties.)

CHANGE THE WAY YOU EAT (AND DRINK)

Pick the healthiest protein.

It may come as a surprise to learn that the only component of your body more abundant than water is protein. You need protein in order to keep your cells, tissues, and organs growing and functioning properly. It also contributes to the health of everything from your muscles, hair, and skin to various hormones and neurotransmitters, which all require a steady supply of the 20 amino acids that are the building blocks of protein. A portion of these amino acids are made by your body, but the rest —the essential amino acids —must come from the food you eat.

Protein is also a critical part of your diet because of its role in maintaining a healthy metabolism. It stimulates the release of metabolic hormones that help stabilize your blood sugar levels and stop energy crashes. As a result, eating or snacking on protein helps you feel full longer than you do after a high-carb or sugary snack or meal. And because protein takes more energy to digest, you also wind up burning more calories.

With all these benefits, you might think you need to eat lots of protein to stay healthy, but small quantities are all that is required. In fact, consuming too much can be detrimental, as it accelerates the internal processes (oxidation, inflammation) that contribute to faster aging and disease. Our recommendation at Amen Clinics is to eat a limited amount with every meal and snack, every four to five hours, to help balance your blood sugar and decrease cravings.

Given that small doses are better for you than large ones, it becomes even more important to choose the highest-quality protein. High-quality animal protein, whether lamb, turkey, chicken, beef, or pork, is free of hormones and antibiotics, free range, and grass fed. Though it is more expensive than industrial farm-raised animal protein, it is a good investment in your health. Compared with grass-fed meat, industrially raised meat is about 30 percent higher in palmitic acid (a type of unhealthy saturated fat), which has been linked with cardiovascular disease. And don’t forget fish, beans and other legumes, raw unsalted nuts, and high-protein veggies, such as broccoli and spinach. Fish, poultry, and most meats contain all the necessary amino acids, while plant foods contain only some of them. However, plant foods are an essential part of a healthy diet —not just for their protein, but also for their many disease-preventing phytonutrients. See “Go for the greens (and reds, yellows, blues, and other hues)” for more information.

Say, What’s Wrong with Soy?

Get your fill of the right fats.

You may be thinking, Why is fat so high on this checklist? It is because healthy fats are essential to keeping your body and brain disease-free. A case in point: A Mayo Clinic study found that the risk of cognitive impairment was 42 percent lower in people who ate a fat-based diet; 21 percent lower in those who ate a protein-based diet; but four times higher in those who ate a simple carbohydrate–based diet (think bread, pasta, potatoes, rice, and sugar).[581] It’s the sugar, not the fat, that’s the problem (see more in “Choose brain-boosting carbohydrates” and “Say good-bye to sugar”).

The war on fat is over —at least in terms of dietary fat. It is clear that your body needs good fats for a variety of essential functions, from storing energy and maintaining healthy brain function to creating healthy cells and hormones. Eating more of the right fats will also help you lose body fat. Research has shown that eating a moderate-fat versus a low-fat diet (35 versus 20 percent of calories from fat) can mean the difference between losing weight and waistline inches and actually gaining both! A moderate-fat diet has another advantage: Healthy fats help with satiety —feeling full. In the study mentioned above, 54 percent of the moderate-fat dieters were able to follow their program for the entire 18 months, while only 20 percent of the low-fat dieters were able to stick with theirs.

Notice that I keep reiterating the terms good and healthy in describing the fats you should be eating. You still need to avoid the so-called bad fats: fried fats, trans fats, and some saturated fats. Here is a look at how different kinds of fats impact your health.

Go for the greens (and reds, yellows, blues, and other hues).

If you were to do nothing else to change your diet except eat more colorful fruits and vegetables, you would still get enormous benefits from the nutrients, vitamins, and minerals they contain, which your body needs for robust health. Broccoli and other cruciferous vegetables, for example, as well as various herbs and spices (e.g., curcumin) contain sulforaphane, which powerfully assists in DNA repair. Foods from plants of every color, even white, also help prevent cancer and reduce the inflammation that contributes to Alzheimer’s disease, heart disease, arthritis, gastrointestinal disorders, and many other illnesses. Plant nutrients bolster your immune system in its role of fending off attacks and disease. (Just be sure to eat twice as many vegetables as fruits to avoid the extra sugar.)

Some of the most age-defying ingredients in produce are its antioxidants, which decrease the destruction caused by free radicals in the body. A food’s antioxidant capacity is measured by its oxygen radical absorbance capacity or ORAC value; see opposite page. Blueberries have a well-deserved reputation for being a brain-healthy food, but it’s clear from this chart that acai fruit and raspberries have even more antioxidant clout and that a number of herbs and spices —cloves, oregano, rosemary, thyme, cinnamon, turmeric, and sage —have true antioxidant superpowers. (Read more about them in “Flavor your food with brain-smart herbs and spices,” page 275.)

Choose brain-boosting carbohydrates.

It makes perfect sense to discuss the best carbohydrates for your brain right after touting the benefits of fruits and vegetables because some of the healthiest carbs are . . . fruits and vegetables! Veggies like brussels sprouts and asparagus, which are nonstarchy, and fruits like pears and apples are complex carbohydrates, the best kind of carbs to eat as they are high in fiber, slower to digest, and low glycemic (which means they don’t cause your blood sugar to shoot up). If you can swap foods like these for the high-glycemic, low-fiber carbs in your diet —the doughnuts, pizza, candy, cookies, French fries, and such —you’ll be on a fast track to improving your insulin and blood sugar levels, reducing your cravings, and bettering your memory.

Keeping insulin in check is critical to your overall mental and physical health. It’s a hormone that helps determine how the calories you eat are used by your body. It is manufactured in the pancreas, which boosts production when you consume more simple carbs like sugar, processed grains, potato chips, and other foods that are quickly converted to sugar. Research by Harvard endocrinologist and obesity expert David Ludwig, MD, PhD, has shown that insulin tends to increase both the size and number of fat cells. When insulin levels are high, fat cells accumulate more and more glucose and fat. Staying on this kind of diet makes it impossible, practically speaking, to lose weight. The answer? Wean yourself off of the insulin-boosting simple carbohydrates and replace them with hunger-satisfying, high-fiber, low-glycemic carbohydrates.

MEET THE GLYCEMIC INDEX (GI) AND GLYCEMIC LOAD (GL)

These two rating systems can help you make better food choices. The glycemic index (GI) ranks carbohydrates on their effect on blood sugar, using a scale of one to 100+ (glucose is 100). GI foods with a lower number tend to be healthier because they don’t spike blood sugar; foods with a higher GI number are generally less healthy because they quickly raise blood sugar. In general, it’s healthiest to stick with foods that have a GI value under 60. One surprising finding from the research: Table sugar is ranked lower on the GI than potatoes and bread!

Glycemic load is an even more valuable number because it takes both blood sugar and portion size into account. Pineapple, for instance, has a high GI (66), but a low GL (6). That means you have to eat a lot of pineapple to raise your blood sugar. A low GL is 10 or under (for a comprehensive list of GL foods from the American Diabetes Association, see http://care.diabetesjournals.org/content/suppl/2008/09/18/dc08-1239.DC1/TableA1_1.pdf). Don’t assume, however, that a food with a low GL is automatically good for you. Milk, for example, has a low GL, but it may be adulterated with antibiotics and hormones. To be sure your diet is healthy, check that the foods you are eating meet all the Memory Rescue Diet principles.

FIBER: A VITAL CARBOHYDRATE

Fiber is an unsung dietary hero. It provides a raft of health benefits, including balancing blood sugar, helping you feel full after a meal, reducing colon cancer risk, and keeping your bowels working smoothly. Yet most of us get far too little. The average American consumes less than 15 grams of fiber a day; compare that to the estimated 135 grams our prehistoric ancestors used to eat! The recommended amounts today are 25 to 30 grams for women, and 30 to 38 grams for men.

There are two types of fiber —soluble and insoluble. Soluble fiber, found in foods such as apples, blueberries, beans, oatmeal, and fiber supplements, helps prevent heart disease and diabetes. It also feeds the good bacteria in your gut, boosting immunity and helping limit the growth of bad bacteria (see chapter 7 for more on the role of gut bacteria in brain and body health). Insoluble fiber —what we think of as roughage —is found in seeds, stems, and skins. It helps keep the intestines cleaned out and distributes the critical by-products of soluble fiber throughout the colon.

Eating lots of vegetables will significantly increase your intake of both soluble and insoluble fiber. Fiber supplements also can be helpful, especially if you are insulin resistant or have high cholesterol.

TROUBLESOME GRAINS

Many people look to breads and pasta as their primary sources of fiber; however, their health benefits are dubious at best. Sadly, the wild grains that our ancestors ate in tiny amounts bear little resemblance to the genetically hybridized grains produced today. I say sadly because our digestive systems are simply not equipped to process these modern grains —especially since the quantity we now consume has increased exponentially since the agricultural revolution began 300 years ago.

Modern grains are problematic in at least two ways. First, many of them turn to sugar in the body. And second, several —wheat, barley, rye, kamut, bulgur, corn, and spelt —contain gluten (the Latin word for glue), a sticky substance that gives bread dough its elasticity and helps it rise. Gluten has found its way into commercially made breads, cakes, cookies, cereals, pasta, and other grain-based products, as well as salad dressings, sauces, processed foods, and even cosmetics. And that has given rise to gluten-related health issues, including the autoimmune illnesses celiac disease, type 1 diabetes, and Hashimoto’s disease. Gluten can also cause flu-like symptoms, psychological disturbances, acne, arthritis, and food addiction and increase insulin resistance. And it can lower brain blood flow.[586] According to the Center for Celiac Research, 18 million Americans have gluten sensitivity, which can lead to more than 100 symptoms, including chronic diarrhea, bloating, flatulence, nausea, abdominal pain, skin rashes, fatigue, and mental fogginess. Gluten-free diets are associated with a reduction, and even full remission, of symptoms in a subset of schizophrenic patients[587] and improvement in autistic and ADHD symptoms in a subset of patients.[588]

Another troublesome grain is corn. Its unhealthy fatty-acid profile (high levels of omega-6 fats plus very low levels of omega-3s) makes it an inflammatory food that can damage the intestinal lining. Of particular concern is the widespread use of Roundup (a highly toxic glyphosate pesticide that is banned in some European countries) on US corn,[589] most of which is raised from genetically modified seeds. Glyphosate has been associated with ADHD,[590] cancer, depression, Parkinson’s disease, MS, hypothyroidism, and liver disease.[591]

Corn is ubiquitous in America, from corn oil to cornstarch to corn syrup and beyond, but you can greatly reduce your intake by avoiding processed foods and recipes containing corn kernels. That was true for Victor, who had suffered with anxiety, depression, and insomnia for decades. He had seen endocrinologists, psychiatrists, cardiologists, and sleep doctors but found no relief.

After a week on the Memory Rescue eating plan, his mood was better than it had been in years. When Victor added corn back into his diet, he said that “within a couple of bites” he knew it was the problem. Although he loved corn chips, corn tortillas, and popcorn, he decided the relationship wasn’t worth the pain, so he broke up with corn. He was amazed that after suffering for so long, he could feel happy by doing something so simple.

Animals Need Good Food Too

Say good-bye to sugar.

Arguably the worst carbohydrate in terms of your overall health is sugar. Per person, Americans eat about 140 pounds of sugar a year. Refined sugar is 99.4 to 99.7 percent pure calories, with no vitamins, minerals, or other redeeming ingredients. And don’t be fooled: Whether it comes from a beehive, a maple tree, or any other natural source, it is still sugar. In the past several years, many sources have suggested that diabetics should use the sweetener agave because of its high fructose content (a staggering 80 to 90 percent). Fructose is often called a low-glycemic sweetener because unlike sucrose it doesn’t cause insulin to spike. However, fructose is toxic to the liver and may trigger metabolic syndrome, fatty liver, and insulin resistance.

When you eat any form of sugar, your blood sugar spikes, your pancreas releases insulin, your blood sugar drops, and you long for something sweet . . . which restarts the same cycle. Thus, when you eat sugar and simple carbs, you wind up craving them like a drug addict craves his drug.

Of course, that’s just one of sugar’s ill effects. Eating sugar and sugary foods increases inflammation and erratic brain cell firing, causes mineral deficiencies and overweight, and has been associated with increased triglycerides, as well as lower HDL and higher LDL cholesterol. As for its impact on the brain, sugar consumption has been linked with depression, ADHD, hyperactivity, and increased slow brain waves in brain imaging studies. Research at UCLA showed that sugar affects learning and memory as well.[592]

How to Identify Sugar on Food Labels

ARTIFICIAL SWEETENERS: NOTHING SWEET ABOUT THEM

Consuming artificial sweeteners regularly is not a recipe for good health. It can contribute to chronically high insulin, which increases your risk for Alzheimer’s disease and raises the risk of heart disease, diabetes, metabolic syndrome, and other health problems. It’s a fallacy that artificial sweeteners help you lose weight; on the contrary, they may lead to weight gain because they may lower metabolism. Animal research has shown that artificially sweetened food slowed metabolism and led to greater weight gain than sugar-sweetened foods —even though those animals eating the sugary foods consumed more calories. The bottom line: Whether the sweetener is aspartame (NutraSweet, Equal), saccharin (Sweet’N Low), or sucralose (Splenda), it is better to avoid it.

ERYTHRITOL AND STEVIA: BETTER ALTERNATIVES

Erythritol, a sugar alcohol that comes in crystals or powder form, has no calories and doesn’t lead to blood sugar or insulin spikes. Use it with caution until you know how you react to it, since most sugar alcohols (such as xylitol and maltitol) cause GI distress.

Stevia, extracted from the leaf of an herb, is 200 to 300 times sweeter than sugar, but it does not affect blood sugar levels the way sugar does. In fact, it may stabilize blood sugar levels, enhance glucose tolerance, and lower blood pressure, but more research is needed. Note: Consult with a health-care provider before using stevia if you take medication for blood pressure or diabetes. 

Hydrate with H2O.

If you are a man, roughly 60 percent of your body is water; if you are a woman, about 55 percent. The percentage of your brain that is water is even higher: 80 percent. Water is essential for everything from lubricating your joints, flushing out waste products, and manufacturing hormones and neurotransmitters to regulating body temperature and helping deliver oxygen throughout your body. Not staying adequately hydrated has consequences for both brain and body: Research has shown that performance in tasks requiring attention, memory, and physical performance are diminished when you are just 2 percent dehydrated.[594] The elderly, in particular, need to make a point of drinking water because the mechanism that triggers thirst can become less efficient with age.

Staying adequately hydrated —which I define as drinking eight to ten glasses of clean water a day —is especially important if you are losing weight. First, it helps prevent overeating. When you think you’re hungry, you may actually be thirsty. Second, your body needs water to flush out the toxins released by stored body fat. Finally, if you drink two glasses (16 ounces) of water 30 minutes before a meal or snack, you can eat less and still feel satisfied. But dieting or not, avoid drinking water with your meals because it dilutes stomach acid, slowing digestion.

Cutting out sweet beverages like soda and fruit juice eliminates an average of 400 calories per day from the typical American diet!

Just as important as downing enough water is limiting liquid calories and dehydrating drinks. Replace sodas (including diet sodas), fruit juices, and other sugary drinks with water. (You can either swap those calories for an equivalent amount of healthier food or cut them entirely and could lose 40 pounds in one year.) Avoid caffeine, alcohol, and other diuretics, and when you sweat during exercise, be sure to replace those fluids.

Move on from Cow’s Milk

Swap regular butter for clarified butter, or ghee. It’s the pure butterfat that remains once the allergenic milk proteins, casein and whey, have been removed.

Flavor your food with brain-smart herbs and spices.

It’s easy to forget that herbs and spices are not just flavor enhancers for food, but promoters of good health too. These plant-derived seasonings have a long history of medicinal uses that you can capitalize on in your cooking. (For ideas on how to incorporate them into your cooking, see The Brain Warrior’s Way Cookbook.) Here are some of the most powerful memory-enhancing herbs and spices, along with a few of their benefits.

TAKE A BRIGHT MINDS APPROACH TO THE FOOD YOU EAT

Based on these 10 nutrition principles, here is a reminder of what to eat —and what to avoid —from a BRIGHT MINDS viewpoint. Knowing your personal risk(s) will help you choose the areas to focus on.

Blood Flow

FOODS TO CHOOSE

Spices: cayenne pepper,[600] ginger, garlic,[601] turmeric,[602] coriander and cardamom,[603] cinnamon,[604] rosemary, and bergamot (for cholesterol-lowering properties)

Arginine-rich foods to boost nitric oxide and blood flow: beets, pork, turkey, chicken, beef, salmon, halibut, trout, steel-cut oats, clams, watermelon, pistachios, walnuts, seeds, kale, spinach, celery, cabbage, and radishes. Drinking nitrate-rich beet juice has been found to lower blood pressure, increase stamina during exercise, and in older people, boost blood flow to the brain.[605]
