Beans
Beans, although widely consumed for their protein content, are rich in antioxidants. There are several types of beans, but studies show that green broad beans contain about 2 mmol of antioxidants per 100 g. [24]
A type of antioxidant called kaempferol [25] is present in many types of beans. According to research, kaempferol has strong anti-inflammatory properties and is active against many types of cancers. [26]
Artichokes
Artichokes are vegetables native to the Mediterranean that have long been used in traditional treatments of health conditions like jaundice. They contain a lot of fiber and are rich in antioxidants. Studies show that 100 g of artichokes contain about 4.7 mmol of antioxidants. [27]
This vegetable is rich in chlorogenic acid, [28] an antioxidant that promotes [29] heart health and helps in cancer and type 2 diabetes prevention. If you want to get the most antioxidants from this vegetable, steam it instead of frying it.
Conclusion
Antioxidants protect your body from damage caused by free radicals. While your body produces some antioxidants naturally, increasing how much you get from your diet has many health benefits. These foods reduce your risk of cancer and heart disease, among other health conditions.
