The Dietary Reference Intakes (DRI) were
developed to prevent deficiency diseases

50 nutrients
Recommended diet:
Complex carbohydrates, low in fats, high in
fiber, high in protein, low in calories

canola, and peanut oil

Carbohydrates, Proteins and fats are
macronutrients because they are required by
the body in large amounts.
Minerals and vitamins are micronutritients
because they are required by the body in
smaller amounts.
