Diet-related factors affecting foods include the structure of food, the chemical form of a particular nutrient, interactions between various nutrients and foods, and the processing or treatment of a particular food.What does this mean?

The rigid cell wall of plant cells can make the nutrients in plants less bioavailable or usable when eaten. Health or life-stage similarly affe...
