History & Facts

Bell peppers, or capsicum annum, are a type of fruit that belongs to the Grossum plant group also known as the nightshade family (1). Some of the other members of this family include eggplant, tomatoes, and potatoes. In different places of the world, bell pepper is also known as paprika, sweet pepper, pepper, capsicum, and mangoes. Other varieties of capsicum are considered chili peppers because of their pungency but come from the same family. 

Bell peppers most commonly are seen in the colors green, yellow, orange, and red but may vary to other color hues, too (2). Green bell peppers are unripe which is why they often are less sweet than the fully ripe ones like red bell peppers. Green Bell Peppers do not receive all the natural sugars that a pepper would normally get from the ripening process. This causes them to typically have a more bitter flavor when comparing them to the others. 

Bell peppers are sometimes dried and powdered and this is considered paprika. Paprika often has a sweet yet slightly smoky flavor. 

Native to Mexico, Central the Caribbean, and northern South America, bell peppers were imported to Spain in 1493 and then spread from there. Today, global production of bell peppers is around 36 million tons per year, with China being the leading producer, followed by Mexico, Indonesia, and Turkey. The United States ranks 5th in total production, producing approximately 1.6 billion pounds annually. 

Summary:Bell peppers are native to the Mexico and South American areas and come in all different colors.

Nutrition Facts 

Bell peppers pack a punch with all the nutrients they contain. 


In a 3.5-ounce (100-gram) serving of raw red bell peppers, there are the following macronutrients (3): 

  • Calories: 31 calories (kcal)
  • Protein: 0.9 grams (g)
  • Total fat: 0.13 grams (g)
  • Carbohydrates: 6.65 grams (g)
  • Fiber: 1.2 grams (g)

Bell peppers are relatively low in calories at a whopping 31 calories per serving (4). They contain mostly carbohydrates which is where their sweet flavor comes from (5). Other than carbohydrates, they are primarily composed of water, 92% in fat. This makes them a food that can help curb appetite, promote hydration, and potentially aid in weight loss. 

Additionally, bell peppers are a good fiber source which is an important key nutrient (6). Most Americans do not get adequate fiber in their diets. Eating a diet rich in fiber can help increase the feeling of fullness, reduce blood sugar spikes, lower cholesterol, and promote gut health (7).  Additionally, they are a low glycemic index food, which means eating them won’t typically spike your blood sugar very high. This can be beneficial for people with type 2 diabetes.

Summary:Bell peppers are low in calories and high in water and fiber content. Because of this eating them could help with things like curbing appetite and promoting hydration and gut health.

Vitamins and Minerals

In a 3.5-ounce (100-gram) serving of raw red bell peppers, there are the following vitamins and minerals (8):

  • Calcium: 6 milligrams (mg)
  • Magnesium: 11 milligrams (mg)
  • Phosphorus: 27 milligrams (mg)
  • Potassium: 213 milligrams (mg)
  • Sodium: <2.5 milligrams (mg)
  • Vitamin C: 142 milligrams (mg)
  • Niacin: 1.02 milligrams (mg)
  • Folate: 47 micrograms (mcg) 

Overall, bell peppers are a very good source of vitamin C (9). Vitamin C is a potent antioxidant necessary for immune health and promoting skin health (10). 

They are also high in folate and potassium (11). Folate, an important B vitamin, helps to maintain normal tissue growth and cell function (12). Potassium is a mineral that is involved in many processes and metabolic functions in the body, one of which is regulating blood pressure (13).

Other than vitamins and minerals, bell peppers naturally contain several plant compounds. The plant compound varies typically depending on which color of bell pepper is being consumed. Capsanthin, a potent antioxidant is especially high in red bell peppers and gives them their rich color (14).

Violaxanthin is a type of carotenoid antioxidant in yellow bell peppers. Lutein and quercetin are in all bell peppers but most abundantly in green bell peppers (15). Both of these compounds are antioxidants that may have positive effects on eye health and prevent conditions like heart disease and cancer. 

Bell peppers also contain capsaicin (16). Capsaicin is one of the components in peppers that give them their sometimes spicy and unique flavor. In bell peppers, it is present in small amounts which the makes spice in them very mild. Believe it or not, capsaicin may provide analgesic properties for some. It has been used as a homeopathic remedy to treat burning pain. The research concludes that capsaicin may effectively treat several conditions, including osteoarthritis, chronic musculoskeletal pain, sore throat, burning mouth syndrome, and more. 

Summary:Bell peppers are high in vitamin C, folate, and potassium. They also contain different compounds in addition to capsaicin which offer different health benefits.

In general, for healthy individuals who have not had adverse reactions to nightshade foods, there is no reason to avoid them. If there is more of a severe reaction like a rash or breathing problems, this could be more indicative of an allergy and should be addressed with a medical provider.
