Bell pepper, also known as sweet pepper, is one of the most commonly used chili peppers in the Capsicum annuum family and is native to Mexico and northern Latin America. These are scientifically known as Capsicum annuum and belong to the category of nightshade (solanaceae) family of plants comprising of cayenne pepper, chili pepper, potatoes, tomatoes and eggplant.  Bell peppers are fruit pods on the capsicum plant grown for their subtle hotness yet sweet, delicate peppery flavor they extend to the recipes. Botanically, it is a small perennial shrub in the nightshade or Solanaceae family, in the genus, capsicum.

In that case they are referred to as paprika. They are low in calories and exceptionally rich in vitamin C and other antioxidants, making them an excellent addition to a healthy diet.

Capsicum spp. has a long history of cultivation and utilization. It was consumed by the Indians of South and Central America as early as 7000 BC, and the plant was cultivated in fields some 2000 years later. Perry and Flannery (2007) reported the presence of the plant at the Guilá Naquitz cave in Oaxaca, Mexico. The state of Oaxaca is one of the centers of origin of C. annuum, where archaeobotanical traces date back from 600 to 1521 BC. It is noted that the peppers have been part of the Mexican diet for at least a century.

Following the period of early Spanish colonization of the Americas, the plant was brought to Europe and then introduced to other tropical, subtropical, and temperate countries. It was spread to Central Europe by the Turks during the period when the Ottoman Empire extended as far north as Hungary. The Turks appeared to have first encountered it in 1513 at Hormuz, a Portuguese colony in the Persian Gulf.

The most common types of visual deficiencies are macular degeneration and cataracts and main causes are old age and infections. Though, nutrition plays a significant role in the development of these diseases.

Bell pepper consists of higher amount of Lutein and zeaxanthin, carotenoids which may improve eye health considerably when consumed in sufficient amounts. In fact, they protect the human retina, the light-sensitive inner wall of the eye, from oxidative damage.

Research indicates that regular consumption of foods rich in these carotenoids help to cut the risk of both cataracts and macular degeneration. Therefore including bell peppers to your regular diet may be an excellent way to lower the risk of visual impairments.(1), (2), (3), (4), (5), (6), (7), (8), (9), (10), (11), (12)

As discussed before bell pepper is rich in antioxidant and anti-inflammatory nutrients which provide several anti-cancer benefits. The risk of cancer increases due to chronic excessive inflammation and chronic unwanted oxidative stress. These factors can be counterbalance with regular intake of phytonutrients having antioxidant and anti-inflammatory properties. Besides, bell peppers also contain health supportive sulphur compounds. The enzymes found in bell pepper help to prevent gastric cancer and esophageal cancer. Carotenoid lycopene found in bell pepper is also effective in the prevention of prostate, bladder, cervix and pancreas cancer.

3. Prevention of Anemia

Anemia is a common condition described by reduced ability of the blood to carry oxygen. One of the most common causes of anemia is iron deficiency and main symptoms are weakness and tiredness.

Apart from being a decent source of iron, bell peppers are also exceptionally rich in vitamin C, which increases the absorption of iron from the gut. One medium-sized red bell pepper may contain 134% of the recommended dietary allowance (RDA) for vitamin C.

Absorption of dietary iron is significantly increased with the regular consumption of fruits and vegetables that are rich in vitamin C. For this reason, consuming bell peppers with iron-rich foods, such as meat or spinach, may help increase your body’s iron stores, decreasing the risk of anemia.(13), (14)

4. Weight Loss

Bell peppers are very low in fat and calories- about 1 gram of fat and 29 calories per cup- which makes them a perfect snack option, or a great supplement for a main meal. This small amount of fat is sufficient to provide a reliable storage for bell pepper’s fat-soluble nutrients.

5. Anti-inflammatory properties

Bell pepper or capsicum consists of phytochemical constituents that are shown to produce an anti-inflammatory response that proves to ease peripheral neurogenic pain such as related to Crohn’s disease, an inflammatory disease of the bowel. Another example of peripheral neurogenic inflammation is cutaneous pain of the skin. Its creams and balms are often massaged topically onto the skin with care taken to avoid open areas and mucous membranes. The burning effect of capsicum is felt when applied to the skin. This is caused by an inflammatory response of the peripheral nerve endings, but regular application deadens the sensory nerve endings which relieve chronic diabetic neurogenic pain. Some recommend that the anti-inflammatory effect of capsicum help to relieve pain related to arthritis. Its cream can also be used as an option for treating this malady and many others.(15)

6. Cardiovascular Health

Research has recommended that flavonoid present in bell pepper is beneficial towards preventing coronary heart disease. Capsicum is both warming and vasodilative. Suggested effect of the vasodilative properties of capsicum is the improvement of hypotension and decreased heart rate. Vasodilatation allows for improved blood flow resulting in better oxygenation of organ tissues. This is most likely due to the tachynikins, a known bioactive ingredient in capsicum.

7. Supports the Immune System

Vitamin C present in Bell pepper is vital for maintaining a healthy immune system and for building strong collagen to support skin and joints. It is helpful in lowering the risk of arthritis and reducing inflammation. Apart from that Vitamin K aids in the formation of blood clots. It is important for developing strong bones and protection of cells from oxidative damage.

8. Strengthens Hair Follicles

Bell pepper is quite beneficial for hair as they are excellent sources of vitamin C which is essential for hair health. Vitamin C helps in proper absorption of iron, therefore ensuring that there is enough iron in red blood cells to carry oxygen to hair follicles. Vitamin C is also used in the formation of collagen. Collagen is required by hair follicles, blood vessel and skin to stay healthy and for their optimal growth. Vitamin C deficiency can cause dry, splitting hair that breaks easily.

9. Hypoglycemic

With the world wide prevalence of diabetes, the consideration of capsicum as hypoglycemic medicinal has motivated research into this matter. Some research have indicated, though not yet concluded that capsicum may stimulate insulin production which results in lower blood glucose. This would determine a possibility of capsicum to beneficial in preventing onset of type II diabetes and its potential complications. The hypoglycemic benefits of capsicum are most concentrated when the capsicum chili is green.(16)

10. Psoriasis

Several researches showed the effectiveness of Capsicum for treating symptoms of fibromyalgia when applied topically. Those using capsicum topically stated beneficial effects in decreasing tenderness and improvement of sleep.

11. Mucilage

Capsicum is one of the best sources of tannins. Tannins are astringent and are often considered for their benefits when treating gastrointestinal disorders that produce diarrhea such as dysentery and other microbial disorders. Gastric mucilage acts to protect the gastric lining. A causative effect of peptic ulcer development is the breakdown of gastric mucilage which is causative of the ulcerations made with increased gastric acid contact with stomach lining. It works as mucilage when ingested by increasing the production of gastric mucus.

Increased gastric mucus and the anti-inflammatory properties of capsicum may result in beneficial effects in the treatment of peptic ulcer disease. Another example of the reliability of capsicum in producing mucus that is more readily observable is that of increase nasal drainage when ingesting peppers with high concentrations of the heat producing phytochemical capsicum. Also for this reason, it is beneficial to avoid touching eyes and bodily mucus membranes during preparation of capsicum peppers and to wash hands thoroughly after preparation to avoid transferring volatile oils containing capsicum to these sensitive areas.(17)

12. Healthy Skin

Vitamin E is quite important for better skin health. Vitamin E helps to nourish skin for the healthy development of cells, therefore providing a healthy and supple skin. Bell pepper provides antioxidants and flavonoids that protect skin from free radicals. Free radicals are responsible for skin cells damage leading to aging.
