When it comes to nutrition, one size does not fit all. Foods that are nourishing to some can be harmful to others. Take, for example, tree nuts. Many studies report that eating almonds, Brazil nuts, pecans, pistachios and walnuts regularly tends to improve the nutrient density of diets and has been linked to lower disease and mortality risk. However, if you’re allergic to tree nuts, they are essentially poison to your system. The same is true of many common and otherwise nutritious foods, including dairy, eggs and shellfish. This concept is sometimes referred to as bio-individuality. In practice, the ideal is to become aware of the foods on which your body thrives and which do not agree with you.
