Polyphenols are powerful, biologically active agents and a flourishing topic of research. These phytochemicals derive from plant sources and include hundreds of compounds such as phenolic acids, flavonoids, lignans, and stilbenes. Studies highlight the micronutrients' ability to alleviate and prevent oxidative stress, a culprit behind many chronic diseases. Researchers have discovered that polyphenols are largely responsible for the beneficial effects of foods. Although the FDA has not designated a recommended daily value for polyphenol consumption, experts agree that the compounds, which are more concentrated in some foods than others, offer immense health protection.
Pomegranates derive their bright crimson color from polyphenols. The juice of this fruit has more antioxidants than many other fruit juices. Hundreds of studies, including one published in Molecules in 2017, have linked this food’s high level of polyphenols such as anthocyanins, tannins, urolithins to protective effects; the compounds can guard against parasites, diabetes, ulcers, gastrointestinal disorders, and even cancer. One hundred mL of pure pomegranate juice contains 66 mg polyphenols.
