Have you ever wondered what gives fruits and vegetables their vibrant colors and distinct flavors? The answer often lies in polyphenols, a diverse group of naturally occurring compounds found in plant-based foods. But beyond aesthetics, what does polyphenols do to the body? These potent antioxidants are believed to offer a range of health benefits, from protecting against chronic diseases to boosting brain function.
The Many Wonders What Does Polyphenols Do To The Body
Polyphenols are micronutrients packed with antioxidant activity. They are primarily responsible for defending plants against ultraviolet radiation and pathogens. When consumed by humans, they continue to act as powerful protectors. The most important function of polyphenols is their antioxidant and anti-inflammatory properties, which help to neutralize free radicals and reduce oxidative stress in the body. This process is crucial because oxidative stress is linked to various chronic diseases, including heart disease, cancer, and Alzheimer’s disease.
Different classes of polyphenols exist, each with unique characteristics and potential health benefits. Some of the most well-known categories include flavonoids, phenolic acids, lignans, and stilbenes. Consider how they’re found in various food sources:
- Flavonoids: Found in berries, apples, onions, and tea. They contribute to the vibrant colors of many fruits and vegetables.
- Phenolic acids: Present in coffee, whole grains, and some fruits.
- Lignans: Found in flaxseeds, sesame seeds, and whole grains.
- Stilbenes: Resveratrol, a well-known stilbene, is found in grapes and red wine.
Each of these play a different role in the body, and it’s the variety that makes a diet rich in polyphenols so beneficial.
