Why are polyphenols beneficial?

Polyphenols are a group of nutrients that are found in plants. They have many health benefits due to their antioxidant and anti-inflammatory properties.

Below, we have covered the key reasons why polyphenols are so beneficial and why it’s important to try and consume these compounds in your diet through fruits and vegetables.

Antioxidant properties

Polyphenols help to neutralize oxygen free radicals in the body, which are compounds that are produced during metabolic processes (when our body changes food into energy). Oxygen free radicals can interact with DNA inside the cells and cause damage, increasing the risk of diseases like cancer and neurodegenerative disorders.

Anti-inflammatory properties

Polyphenols have anti-inflammatory properties, meaning they help to reduce the number of inflammatory molecules in your body. Chronic inflammation is a key component of a wide range of illnesses, including cardiovascular disease, diabetes and some cancers.

Cardioprotective effects

Polyphenols can help protect the heart and blood vessels through their antioxidant and anti-inflammatory properties. They can help prevent damage to the blood vessel walls, lower blood pressure and improve blood cholesterol levels.

Protective effects on the brain

Many polyphenols, especially those found in berries and green tea, may also have neuroprotective effects, possibly supporting cognitive function and reducing the risk and rate of age-related cognitive decline.

Improve gut health and digestion

Polyphenols can be beneficial for gut health. They can act as prebiotics, fuelling probiotic bacteria in the gut and aiding a range of positive functions. Probiotic bacteria aid digestion, produce certain vitamins and short-chain fatty acids, improve mood and boost immune function.
