How Polyphenols Fight Inflammation and Boost Long-Term Health

Polyphenols are natural nutrients found in plants and plant-based foods. They help the body manage inflammation and protect against oxidative stress. These compounds offer two key benefits: they act as antioxidants and anti-inflammatories. There are over 1,000 types of polyphenols, grouped into four main categories: phenolic acids, flavonoids, stilbenes, and lignans. They occur naturally in a wide range of foods, including fruits, vegetables, herbs, spices, seeds, nuts, and whole grains.

Dark-coloured fruits and vegetables, along with their skins and seeds, usually contain higher levels of polyphenols. The amount can vary depending on factors like air exposure, water and soil conditions, and the plant's age. Fresh, local, in-season produce tends to have the highest content, though frozen options can also provide good amounts.

As antioxidants, polyphenols combat free radicals, which are linked to diseases like cancer, autoimmune disorders, heart disease, and skin ageing. As anti-inflammatories, they help regulate the body’s inflammatory response, reducing the risk of chronic conditions such as arthritis and Alzheimer’s disease. Eating a variety of colourful, natural foods ensures a good intake of polyphenols. Their antioxidant and anti-inflammatory properties support long-term health. Choosing diverse, plant-based options maximises these benefits.
