Background
Imagine starting your day with a bowl of berries that sharpen your memory, a cup of green tea that protects your heart, and yogurt that fortifies your immune system. The promise of “functional foods”—foods that claim to do more than just nourish—has captured the imagination of health-conscious consumers and clinicians alike. Supermarket aisles now burst with products boasting benefits from gut health to sharper brains, but can we truly eat our way to superpowers?
The term “functional food” is more than a catchy label. According to the International Food Information Council, functional foods are those that provide health benefits beyond their basic nutritional value. These include naturally nutrient-rich foods (like fatty fish or berries) and those fortified with extra vitamins, minerals, probiotics, or phytochemicals. The roots of functional foods stretch back centuries, but scientific interest has surged in recent decades as research unpacks the relationship between diet and disease prevention.
