Polyphenols

Polyphenols are a group of chemical compounds that naturally occur in many plants and are known for their strong antioxidant properties. These compounds play a key role in combating free radicals, which can cause cellular damage and contribute to the development of various chronic diseases, including cancer and heart disease. Polyphenols also support heart health by helping to reduce blood pressure, improve blood vessel elasticity, and lower LDL cholesterol levels.

Nutritionally, polyphenols are important for their potential health benefits. They are found in a wide range of foods, including fruits, vegetables, nuts, chocolate, wine, and tea. Consuming foods rich in polyphenols may help improve digestion, support brain health, and protect against aging. Furthermore, some studies suggest that polyphenols may help regulate body weight and support skin health.

Good day,

I have a question regarding the oxidation of omega-3 in the body: I have learned from several sources that it is advisable to consume them together with polyphenols, which reduce/suppress oxidation in the body. A specific example - sardines: it seems to me that the best option would be sardines in extra virgin olive oil, where I would also consume polyphenols present in the oil. Is my reasoning correct?

Thank you

Omega-3 fats are sensitive to oxidation and can quickly succumb to it under unsuitable conditions. This process can be significantly slowed by storing Omega-3s in a cool environment and without exposure to light, and the presence of antioxidant substances has a crucial influence. However, individual antioxidants boast different effects. In recent years, the influence of polyphenols has been frequently cited, with an interesting source being olive oil (unrefined). If you aim to intake Omega-3 from food, combining fish with high-quality olive oil makes sense. However, keep in mind that you will not have a guarantee that the manufacturer has indeed used high-quality olive oil, that is, with a sufficient content of polyphenolic substances.
