What is a primary role of fortified foods in populations with restricted dietary diversity?

• A. To fill nutrient gaps (e.g., iodine in salt, vitamin D in dairy, iron in cereals)
• B. To replace all need for fresh produce
• C. To cause nutrient toxicity in most people
• D. To be the sole source of nutrition

Answer: (A)

Fortified foods serve to fill nutrient gaps when diets are limited in variety. By adding essential micronutrients to widely consumed staples—like iodine to salt, vitamin D to dairy, and iron to cereals—these foods raise overall intake of nutrients that people are likely to miss in low-diversity diets. This approach helps improve public health by reaching many individuals through foods they already consume, supporting functions such as thyroid health, bone health, and red blood cell formation. It isn’t meant to replace fresh produce or to be the only source of nutrition, and when implemented with proper guidelines it doesn’t aim to cause toxicity for most people.
