Capsicum Nutrition Facts

Using whole chili peppers from the Capsicum genus provides nutritional value, including high amounts of vitamin C and vitamin A.

These vitamins are best obtained from the fresh fruit.4 Capsicum chili harvested when red rather than orange or yellow have higher concentrations of these beneficial nutrients.4 Other beneficial bioactive components of the capsicum chili are the content of flavonoids.4 Alkaloids and tannins are some of the other important bioactive compounds contained in it.4 Alkaloids work as anti-inflammatory, analgesic, and antioxidant agents.4

Health Benefits of Capsicum

Adding capsicum to your daily diet may provide great health benefits against many ailments. Let us look at the benefits in detail.

Anti-inflammatory Agent

The phytochemical constituents of capsicum are shown to produce an anti-inflammatory response that alleviates peripheral neurogenic pain related to Crohn’s disease, an inflammatory disease of the bowels.5 Another example of peripheral neurogenic inflammation is a cutaneous pain of the skin.5 Capsicum 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, which is caused by an inflammatory response of the peripheral nerve endings. But regular application deadens the sensory nerve endings and relieves chronic diabetic neurogenic pain.5 Some suggest that the anti-inflammatory effect of capsicum may also help alleviate pain related to arthritis.4 Its cream may be utilized as an option for treating this malady and many others.

Forms Mucilage

Capsicum contains tannins. Tannins are astringent and are often considered for their benefits when treating gastrointestinal disorders such as diarrhea, dysentery, and other microbial disorders.4 Gastric mucilage acts to protect the gastric lining and prevent peptic ulcer development.6 Studies suggest that it acts as a mucilage by increasing the production of gastric mucus and help treat peptic ulcer disease. Intake of capsicum may increase the nasal drainage due to the presence of phytochemical capsaicin.

Also, for this reason, it is beneficial to avoid touching the eyes or bodily mucus membranes during the preparation of capsicum peppers. Also, wash your hands thoroughly after preparation to avoid transferring volatile oils containing capsicum to these sensitive areas.

Prevents Cancer

Another bioactive effect of tannin contained in capsicum is in the prevention and treatment of cancer.4 Studies have shown that it has an inhibitory effect on many types of malignant cancers.6 These anti-tumor properties are most beneficial in treating pulmonary, hepatic, and gastric cancers.6 The antioxidative effects of capsicum show a possibility of treatment for other types of cancer, such as hormone-related prostate cancer.6

The anti-cancer effect of capsicum is determined by the bioactive ability of the phytochemical capsaicin to inhibit cancer cell growth. Capsaicin also causes destruction of already damaged cellular structure in the human body.6

Improves Heart Health

Studies on flavonoids have suggested that they are beneficial towards preventing coronary heart disease.4 Capsicum is both warming and vasodilative.4 A suggested effect of the vasodilative properties of capsicum is the improvement of hypotension and decreased heart rate.4 Vasodilatation allows for improved blood flow resulting in better oxygenation of organ tissues. This is most likely due to the tachykinins, a known bioactive ingredient in capsicum.4

Antioxidant Agent

Many of the bioactive compounds of capsicum provide antioxidant effects.4 Improved vasodilatation allows for these antioxidant phytochemicals to circulate throughout the body.4 This allows it to protect and repair tissues and DNA damage.4


With the worldwide prevalence of diabetes, the consideration of capsicum as hypoglycemic medicine has provoked research into this matter.2 Some studies have indicated, though not yet concluded that it may stimulate insulin production which results in lower blood glucose.2 This would determine a possibility of capsicum being beneficial in preventing the onset of type II diabetes and its potential complications.2 The hypoglycemic benefits of capsicum are most concentrated when it is green.2

Boosts Immunity

Capsicum contains vitamin C, which is valued as an immune supportive bioactive phytochemical.4 It helps in strengthening the immune system, repairing damaged brain tissues, and lowering the risk of oxidative stress, pediatric asthma, and cancer. It also improves bone health.

Treats Fibromyalgia

Many clinical trials show the effectiveness of capsicum for treating symptoms of fibromyalgia when applied topically.7 Those using capsicum topically stated beneficial effects in the improvement of sleep.7

Treats Diabetic Neuropathy

A disease that often produces neurogenic pain is diabetes.5 Capsicum is shown to have a beneficial effect on diabetic neuropathic pain when applied topically.5 It works to deaden cutaneous nerve endings and reduces the pain.5

Skin Care

Vitamins in the capsicum chili pepper are shown to have an antioxidant effect on cell tissues, which may improve skin health and prevent aging.4

Relieves Menopausal Symptoms

Menopausal symptoms may also be relieved by the consumption of flavonoid-containing fruits such as capsicum chili.4


Capsicum comes in dried form, as a spice as chili pepper and paprika.4 The dried spice is used in many sauces, or added to beverages such as tea.4 Dried capsicum may be found in whole dried peppers, as a single spice or in dried spice blends.

As a more concentrated medicine, capsicum may be placed in a capsule for oral ingestion as a nutraceutical or applied topically to the skin as an analgesic and anti-inflammatory cream.

With capsicum chili’s ready availability in many markets, it should be considered that though the dried spice is convenient and effective in its health benefits, eating fresh capsicum chili provides more benefits.


As studies show, capsicum is beneficial as a daily health supplement. Capsicum is enjoyed by many as a daily food additive in cooking. Culinary preparation of the capsicum peppers may provide enough protection when eaten daily to have beneficial effects on certain chronic and potentially degenerative health conditions. The bioactive components of capsicum work together to improve blood flow, act as a cancer preventive and an analgesic, protect the gastric mucosa, and provide nutrients for a healthy lifestyle.

Though, all chili peppers contain both vitamins and other beneficial bioactive components. Yet, the color of the pepper determines the stage of growth when harvested. It also determines the concentration of vitamins and other beneficial phytochemicals.2 Overall, it can be said that whether consumed dried or fresh, capsicum chili is a medicine and is beneficial to use in an everyday diet as both, a natural preventive and a treatment for many chronic conditions.
