A food is more than only carbohydrate or fat that food contains. Foods are complex consisting thousands of nutrients. Our body is complex too, requiring many nutrients simultaneously, each in optimal concentration. If only one essential nutrient is too much or too little, cells cannot function in best way even if all other nutrients have perfect concentration. It is impossible to reduce the discussion to one nutrient.
Therefore, we have a holistic approach. We consider all nutrients simultaneously, the many different minerals, trace elements, vitamins, carbohydrates, fatty acids, amino acids. We optimise the concentration of all 60 measurable nutrients. Even further, we consider the remaining hundreds of non-measurable nutrients as well.
We use whole foods instead of food fragments or single chemical supplements.
