FIGURE 1.

A new paradigm for the relation between processing, food health potential, and human health, with an emphasis on food transformation. We propose that food health potential should be first defined by both its food structure and nutrient density (4) and that the impact of processing on these factors should be more systematically and extensively measured. We then propose that processing conditions either decrease or improve food health potential (5). For SAIN/LIM, the SAIN score is a nutrient density calculated by the unweighted arithmetic mean of the percentage adequacy for the food positive nutrients, whereas the LIM score calculates the mean content of disqualifying nutrients in 100 g of food. LIM, a nutrient adequacy score for individual foods that represents the nutrient density per energy unit; PanDiet, probability of adequate nutrient intake that uses the national French and US dietary surveys; SAIN, a percentage of the excess of unwanted components (to limit) per mass unit.
