* A caveat here: If you’re trying to add more fruits, vegetables, and whole grains to your diet and at first you don’t find these foods enjoyable to eat, you need to keep them in your diet long enough to develop a taste for them. These nutrients are so important to your health that you can’t drop them from your diet even if you don’t enjoy them. However, once you learn to love them, you can apply the same “must enjoy” rule: no point in eating a healthy piece of whole-grain toast that tastes like sawdust.
