Vitamins and MineralsRecognize why micronutrients are essential even though they provide no caloriesVitamins and minerals enable countless body processes; a colorful, varied diet usually meets needs without supplements.
Building a Balanced PlateApply the plate method to create balanced meals quicklyHalf vegetables and fruit, one quarter protein, one quarter whole grains, plus healthy fat creates an easy, evidence-based template.

Questions this course answers

What happens when calorie intake consistently exceeds calories burned?

When intake exceeds expenditure, the body stores the surplus as fat for future use.

Which macronutrient primarily repairs and builds body tissue?

Protein supplies amino acids that are the building blocks for muscle, enzymes, and other tissues.

Why are vitamins and minerals called micronutrients?

Micronutrients are required in tiny quantities yet are essential for chemical reactions that macronutrients cannot perform alone.

What fraction of a balanced plate should be vegetables and fruit?

Filling half the plate with produce supplies fiber, vitamins, and volume with relatively few calories.

What is the first thing to check on a nutrition label?

Serving size tells you the amount the listed numbers actually apply to, preventing misinterpretation.
