What Are The Health Benefits Of Chili Peppers?

Chili peppers are the plants known to add a fiery sensation to your tongue and maybe even a droplet of sweat or tears. But chili peppers happen to be associated with much more than just a pungent taste, as their therapeutic use has spanned for centuries. Prospective medicinal benefits of chili peppers have resulted in their perpetual use to cure diverse ailments. Extensive research has identified their potential to aid with pain reduction, cancer, and type II diabetes prevention, as well as cardiovascular health.

Type II Diabetes:

Frequent chili pepper intake has been shown to assist in reducing the risk of hyperinsulinemia, having too much insulin in blood, which is a condition connected to type II diabetes. In 2006, the University of Tasmania in Australia published a study suggesting that the amount of insulin that is needed to lower blood sugar post meal consumption is lessened if chili peppers are included in the meal. When chili peppers are consistently incorporated into meals over time, insulin requirements are reduced even further. 

Pain Relief:

The most active ingredient in chili pepper, capsaicin, is known for its potent pain-relieving properties when used on the skin. The spicy and hot taste you experience is mainly due to capsaicin. When capsaicin is applied to the skin, it releases a chemical called substance P, which is commonly released in response to tissue damage or injury. When hot peppers artificially release substance P, your nervous system thinks that there is an injury and a burning pain results. Administration of capsaicin ointment over time causes a depletion of substance P, lessening the amount of pain in that location. Capsaicin is available in ointment and cream form. It has long been used for the following conditions: 

  • Osteoarthritis and rheumatoid arthritis
  • Joint or muscle pain due to fibromyalgia
  • Nerve pain due to shingles and painful skin, known as post-herpetic neuralgia, which lingers after a shingles attack
  • Pain after surgical procedures such as for cancer or hernia repair
  • Nerve damage pain: This type of pain occurs in the legs or feet as a complication of diabetes, known as diabetic peripheral neuropathy. Research completed in 2012 at the Helsinki University Central Hospital in Finland suggests that high-concentration capsaicin patches demonstrated meaningful efficacy and tolerability for patients suffering from neuropathic pain. 

Cardiovascular Health:

Research on red chili peppers has exhibited reduced blood cholesterol and triglyceride levels. Adding chili peppers to meals has been shown to demonstrate protective effects on the lipids, or fats, in blood from damage by free radicals, a principal step in the development of atherosclerosis. A Tasmanian study at the University of Tasmania in 2006 suggested that eating fresh chopped chili pepper is associated with an increase in the resistance of blood lipids, like cholesterol and triglycerides, to oxidize and cause free radical damage. Both men and women were involved in the study. However, women experienced a greater lag time before damage to cholesterol was observed than those who did not eat chili pepper. Men on the chili diet also experienced a reduced resting heart rate and increased volume of blood reaching the heart.

Cancer:

Research at the University of California at Los Angeles in 2006 found that capsaicin has a profound inhibiting effect on the growth of prostate cancer cells through a variety of mechanisms. Capsaicin triggers cell death in both types of primary prostate cancer cell lines. This research indicates a potential therapeutic regimen for the management of prostate cancer. Further research is also being conducted to examine capsaicin and its association with a reduced risk of breast, colon, gastric, and rectal cancer.

Chili peppers, even when used in small quantities by those who are repulsed by the heat, can lead to long-term health benefits. When added to soups, chicken, beef, stir-fry, and other preparations, these spicy peppers can add a pungent flavor and a boost in your overall health. Try integrating them once a week in small quantities to slowly build a tolerance. With time, you will become more accustomed to the heat when consuming this spicy pepper.

Extensive research has been done and continues to be executed to pinpoint the exact mechanisms in which chili peppers and capsaicin provide therapeutic benefits. Besides these significant health benefits, more research is being completed and suggests chili pepper’s role in weight loss, reduction of inflammation, sinus congestion relief, and antioxidant properties. By incorporating a little extra spice into your meals, there are substantial health benefits that can be gained. So in reality, it makes the heat, sweat, and maybe even the tears worthwhile.
