Fats from both animal and plant sources. Limit saturated and trans fats; favor unsaturated.

Example of a dairy serving.

One cup of milk, 1.5 ounces of cheese, or one cup of yogurt counts as a serving.

What is the role of whole grains?

Whole grains provide fiber, vitamins, and minerals, supporting digestive health and reducing chronic disease risk.
