As for what constitutes a balanced diet, that depends on biochemical and physiological makeup. Achieving balance requires a literal interpretation of the idiom “One man’s meat is another man’s poison.” The big quarrel over what constitutes healthy eating could be resolved if all parties would simply acknowledge the importance of eating what’s appropriate for one’s metabolism. http://academicearth.org/lectures/battle-of-the-diets

The best book on this is “Biochemical Individuality” by Roger J. Williams, PhD. Another book worth reading is “Nutrition and Your Mind” by George Watson, PhD.

It’s interesting that Dr. Watson prescribed macro and micro nutrient regimens according to how a patient’s metabolism was releasing energy. He successfully employed supplements therapeutically to heal metabolism’s warning that what helps one may harm another.

In the end, we should be asking ourselves three questions. Is my diet appropriate? Is it adequate? Is it safe?

Our modern food supply is neither adequate nor safe. Generally, there’s way too much omega-6 and fructose and not enough saturated fat. http://trusted.md/blog/vreni_gurd/2010/02/28/how_good_are_you_at_choosing_healthier_fats
