Bell peppers come in three main colors—red, yellow, and green. More than just a versatile ingredient, they are packed with vitamins, minerals, and powerful antioxidants. According to the health website HealthShots (India), each color of bell pepper offers unique health benefits.

Benefits of Green Bell Peppers

Green bell peppers are among the most widely consumed varieties. They are rich in vitamin C, which is essential for immune function and collagen production. They also provide vitamin K, which supports bone and heart health, as well as vitamin A, which promotes healthy vision and skin.

According to Dr. Archana Batra, a physician and nutrition expert in India, green bell peppers contain folate (vitamin B9), which supports cell division and DNA synthesis, along with potassium, which helps regulate blood pressure.

As a rich source of antioxidants such as lutein and zeaxanthin, green bell peppers may also help protect eye health and reduce the risk of age-related macular degeneration.

A study published in the journal Advances in Nutrition suggests that the fiber found in green bell peppers may support digestive health and help protect against conditions such as colorectal cancer and inflammatory bowel disease (IBD).

Benefits of Red Bell Peppers

Red bell peppers are packed with vitamin C, which helps strengthen the immune system and supports collagen production—an important factor in maintaining healthy skin.

"Red bell peppers are low in calories and may support weight management. They also contain vitamin A, which promotes eye health, and vitamin B6, which supports brain function," says Dr. Batra.

Notably, the vitamin C in red bell peppers may help reduce knee pain associated with arthritis.

The potassium found in red bell peppers may support cardiovascular health, while folate contributes to healthy cell division and DNA production.

Red bell peppers are especially rich in antioxidants such as beta-carotene and lycopene, which are known for their ability to support immunity, reduce inflammation, and lower the risk of chronic diseases, including certain cancers and heart disease.

Benefits of Yellow Bell Peppers

Yellow bell peppers are an excellent source of vitamins C, A, and B6, all of which are important for immune function, eye health, and brain performance.

"This variety also provides important minerals such as potassium and folate, which support heart health and normal cellular function," Dr. Batra adds.

The fiber in yellow bell peppers promotes healthy digestion and may help prevent constipation.

Thanks to their high antioxidant content—particularly carotenoids—yellow bell peppers possess anti-inflammatory properties. These compounds help protect cells from damage and may reduce the risk of chronic degenerative diseases such as cancer, cardiovascular disease, and diabetes.

Which Bell Pepper Is the Healthiest?

Bell peppers come in different colors, and each offers its own unique nutritional advantages.

Among the three varieties, red bell peppers are often considered the most nutrient-dense because they are fully ripened and generally contain higher levels of certain vitamins and antioxidants than green or yellow peppers.

However, according to Dr. Batra, yellow bell peppers actually contain the highest amount of vitamin C among the three.

Overall, all three colors of bell peppers are highly nutritious and provide valuable health benefits. Including a variety of bell pepper colors in your diet is the best way to maximize your intake of vitamins, minerals, fiber, and antioxidants.
