Polyphenols are found in plant based foods that are fantastic for supporting the body in reducing nasties such as free radicals. This is due to the antioxidant properties found in polyphenols. Antioxidants support our bodies from damage caused by free radicals, these are unstable molecules that can lead to oxidative stress and may contribute to chronic diseases. We will have a look at the food groups that contain the most polyphenols, and their four main categories.

Understanding Antioxidants and Polyphenols

Antioxidants are compounds that support the body by neutralising free radicals, reducing oxidative stress and potentially lowering the risk of chronic conditions such as heart disease, cancer, and neurodegenerative disorders. These compounds are naturally present in many foods, particularly in fruits, vegetables, and other plant-based products.

Polyphenols are a group of antioxidants found mainly in plant-based foods. They are known for their anti-inflammatory, anti-carcinogenic, and heart-protective properties. Polyphenols are not just a single type of compound but a different group of substances; here are the four primary categories:

1. Flavonoids: These are the most common type of polyphenols, accounting for about 60% of all polyphenols. Flavonoids are known for their vibrant colours and are found in fruits, vegetables, tea, and herbs. They are ‘heart healthy’.
2. Phenolic Acids: Making up about 30% of all polyphenols, phenolic acids are found in foods such as coffee, tea, berries, and whole grains. They are known for their anti-inflammatory properties and their ability to improve cardiovascular health.
3. Polyphenolic Amides: This group includes compounds like capsaicinoids in chili peppers and avenanthramides in oats. They are known for their anti-inflammatory and antioxidant properties, which can help the body protect against illness.
4. Other Polyphenols: This category includes resveratrol in red wine, lignans in flaxseeds, and curcumin in turmeric. These polyphenols have gained popularity for supporting heart health, and reducing inflammation, particularly for joint pain.

Six Foods Highest in Polyphenols

1. Berries

Berries, including blueberries, strawberries, raspberries, and blackberries, are among the richest sources of polyphenols, particularly flavonoids like anthocyanins, which give these fruits their vibrant colours. Anthocyanins are known for their strong antioxidant and anti-inflammatory effects.

How to include them in your diet: Add berries to your morning oats or yogurt, blend them into smoothies, or just chow them down!

2. Dark Chocolate

A Naturobotanica favourite! dark chocolate is a delicious source of polyphenols, especially flavonoids such as catechins and epicatechins. The higher the cocoa content, the more polyphenols it contains, making dark chocolate a win.

How to include it in your diet: Enjoy a piece of dark chocolate as a daily treat, or add cocoa powder to your smoothies, oats, or our favourite is to grate 80% chocolate over yogurt that has been mixed with honey and cacao powder.

3. Green Tea

Green tea is well known for its health benefits, largely due to its high polyphenol content, particularly catechins. One of the most studied catechins in green tea is epigallocatechin gallate (EGCG), which has powerful antioxidant and anti-inflammatory effects.

How to include it in your diet: Have a daily green tea ritual, in a fancy cup.

4. Herbs

Herbs such as peppermint, oregano, thyme, and rosemary are incredibly rich in polyphenols. Peppermint, in particular, contains high levels of flavonoids and phenolic acids, which contribute to its strong antioxidant and anti-inflammatory properties. These herbs can help support digestive health, reduce oxidative stress, and even improve cognitive function.

How to include them in your diet: Use fresh or dried herbs to season your dishes, brew herbal teas, or add them to salads and soups.

5. Nuts and Seeds

Nuts and seeds, particularly flaxseeds, walnuts, and almonds, are high sources of polyphenols, including lignans and phenolic acids. These compounds contribute to the antioxidant, anti-inflammatory, and heart-protective properties of nuts and seeds. Regular consumption of nuts and seeds supports heart health, and can support weight management.

How to include them in your diet: Add nuts and seeds to your salads, yogurt, or oats.

6. Spices

Certain spices, especially cloves, star anise, and turmeric, are incredibly rich in polyphenols. For example, cloves contain high levels of eugenol, a powerful antioxidant, while turmeric is known for its curcumin content, which has potent anti-inflammatory and antioxidant properties. Spices are a fantastic way to enhance the flavour of your meals while also boosting their nutritional value.

How to include them in your diet: Incorporate a variety of spices into your cooking, from adding turmeric to soups and stews to using cloves and star anise in baking and marinades.

Conclusion

We hope that we have given you some key takeaways in the fact that you can easily incorporate polyphenols into your meals on a daily basis. Also understanding different types of polyphenols and their health benefits, you can make informed choices about the foods you eat.

Also remember that ‘eat the rainbow’ and variety is key; consuming a wide range of polyphenol-rich foods will ensure you get all the benefits that these compounds have to offer.
