Final answer:
Polyphenols are antioxidants found in high levels in organic foods, especially whole fruits, vegetables, and dark chocolate with 70% cacao. These compounds support overall health and are abundant in these unmodified, functional foods.
Step-by-step explanation:
Polyphenols are a category of compounds naturally occurring in plant foods that have antioxidant properties. Studies have shown that organic foods may have higher levels of these compounds compared to conventionally grown foods. Polyphenols are particularly abundant in certain types of foods. For instance, whole fruits and vegetables are rich in phytochemicals and antioxidants, and dark chocolate that contains 70% or more cacao is also a good source of these compounds.
Furthermore, other foods like yogurt and kefir contain beneficial probiotics, which support digestive health but aren't directly related to polyphenols. Maintaining a diet that includes a variety of these whole, unmodified foods can contribute to overall health due to their functional properties.
