Bell peppers come in various colors, such as red, yellow, orange, and green — which are unripe.
Green, unripe peppers have a slightly bitter flavor and are less sweet than fully ripe ones.

- Vitamin C. One medium-sized red bell pepper provides 169% of the Reference Daily Intake (RDI) for vitamin C, making it one of the richest dietary sources of this essential nutrient.
- Vitamin B6. Pyridoxine is the most common type of vitamin B6, which is a family of nutrients important for the formation of red blood cells.
- Vitamin K1. A form of vitamin K, also known as phylloquinone, K1 is important for blood clotting and bone health.
- Potassium. This essential mineral
may improve heart health . - Folate. Also known as vitamin B9, folate has a variety of functions in your body. Adequate folate intake is
very important during pregnancy . - Vitamin E. A powerful antioxidant, vitamin E is essential for healthy nerves and muscles. The best dietary sources of this fat-soluble vitamin are oils, nuts, seeds, and vegetables.
- Vitamin A. Red bell peppers are
high in pro-vitamin A (beta carotene) , which your body converts into vitamin A.
SUMMARYBell peppers are very high in vitamin C, with a single one providing up to 169% of the RDI. Other vitamins and minerals in bell peppers include vitamin K1, vitamin E, vitamin A, folate, and potassium.
Bell peppers are rich in various antioxidants — especially carotenoids, which are much more abundant in ripe specimens.
The main compounds in bell peppers are:
- Capsanthin. Especially
high in red bell peppers , capsanthin is a powerful antioxidant responsible for their brilliant red color. - Violaxanthin. This compound is the most common carotenoid antioxidant in yellow bell peppers (
8 ). - Lutein. While abundant in green (unripe) bell peppers and black paprika, lutein is absent from ripe bell peppers. Adequate intake of lutein
may improve eye health . - Quercetin. Studies indicate that this polyphenol antioxidant may be beneficial for
preventing certain chronic conditions , such as heart disease and cancer. - Luteolin. Similarly to quercetin, luteolin is an polyphenol antioxidant that may have a
variety of beneficial health effects .
SUMMARYBell peppers contain many healthy antioxidants, including capsanthin, violaxanthin, lutein, quercetin, and luteolin. These plant compounds are associated with many health benefits.
Like most whole plant foods, bell peppers are considered a healthy food.
High consumption of fruits and vegetables has been linked to a reduced risk of many chronic illnesses, such as cancer and heart disease.
In addition, bell peppers may have a number of other health benefits.

SUMMARYLike other fruits and vegetables, bell peppers may have many health benefits. These include improved eye health and reduced risk of anemia.
Bell peppers are generally healthy and well-tolerated, but some people may be allergic. That said, allergy is quite rare.
Still, some people that have pollen allergy may also be sensitive to bell peppers due to allergic cross-reactivity (
Allergic cross-reactions can happen between certain foods because they may contain the same allergens — or allergens similar in chemical structure.
SUMMARYWhen eaten in moderation, bell peppers do not have any adverse health effects. However, they may trigger allergies in some people.
Bell peppers are rich in many vitamins and antioxidants, especially vitamin C and various carotenoids.
For this reason, they may have several health benefits, such as improved eye health and reduced risk of several chronic diseases.
