Alimentation et inflammation : considérations épidémiologiques, cliniques et métaboliques
Low-grade systemic inflammation is a key etiological factor in the development and progression of several multifactorial disorders including atherosclerosis, type 2 diabetes and cardiovascular diseases. Increasing evidence suggests that diet significantly modulates the inflammatory profile. However,...
