Eggs

Despite all of the negative press, the egg is one of the best foods for your brain and your temperament. I recommend you eat one whole egg per day (the yolk contains lecithin, which works wonder for the brain cells), especially in the morning if possible. Prepare it any way you like, but without using butter for frying or scrambling. If your cardiologist recommends against a daily egg and makes a reasonable case for why it compromises your cholesterol levels and heart disease risk, ask how many yolks per week is acceptable to boost brainpower without compromising your cardio health. On days when you don’t eat a yolk, substitute a whole soy food like tofu or edamame (buy these green soybeans frozen still in the pod, steam them and lightly salt for a satisfying snack or even a breakfast side dish).
