It has often been said that What you don't know won't hurt you, but we found it smarter, safer, and healthier to take the approach that What you do know can help you. That's the case with polyphenols, about which we have been learning much more in the last decade or two, and that is polyphenols can help us, healthwise for sure, and in a variety of ways. It's close to impossible to go through an entire day that includes three meals and, in that time, not consume at least some polyphenols as part of our diet, even if we aren't aware that we are ingesting them. Polyphenols are micronutrients that are plentiful throughout our dietary choice, and they are active in helping to prevent degenerative diseases, such as cardiovascular conditions, per academic.oup.com. Much of what good they can do on our behalf depends on the quantity of polyphenols consumed – over which we obviously have a lot of control – and their bioavailability.
Polyphenols Have Antioxidant PropertiesAlthough more research needs to be done to confirm whether or not polyphenols are, themselves, actually antioxidants, emerging research has shown that polyphenols do indeed have antioxidant properties. They are good candidates to help thwart diseases associated with oxidative stress, to include neurodegenerative diseases and diabetes, as well as cardiovascular diseases. There's still more to the polyphenols story. They also have been shown to be beneficial as a prebiotic, aiding in the area of stomach health. This is accomplished by ramping up the ratio of good bacteria in the gut, which translates to producing a positive effect in terms of weight management and overall health.
What Else Do We Know about Polyphenols?They are classified as phytochemicals because they are found in natural plant food sources – for which the color/pigment is provided by polyphenols – that have antioxidant properties. Plus, there are more than 8,000 types of polyphenols that have been singled out for identification. The four major classifications of polyphenols are flavonoids, which are anti-inflammatory as well as antioxidant; stilbenes, found in red wine and peanuts; lignans, which can be found in flaxseeds and legumes, among numerous other sources; and phenolic acids, of which there are several sub-classes and 168 different compounds, per nutritionadvance.com.
