Health Benefits of Spicy Chili

Several extensive studies published between 2013 and 2019 show that regular consumption of chili pepper may reduce the risk of death caused by cardiovascular diseases (CVDs). CVDs are disorders that affect the heart and blood vessels.

CVD - The Number One Killer. According to the World Health Organization (WHO), cardiovascular diseases (CVDs) cause 17.9 million deaths per year, ranked number one cause of premature death. In 2016, CDVs were the cause of 31% of all premature deaths, and 85% of these were heart attacks or strokes.

The latest study followed 22,811 Italians' diet and the way of life over eight years. This study shows that the risk of death caused by cardiovascular disease was lower up to 40% for individuals who ate chili more than four times a week. The risk of dying due to complications of bleeding or obstructed blood flow in the brain was reduced by more than 50%.

The preventive effect was lowest for those who didn't have high blood pressure. Interestingly, the effects were not dependent on the diet in general.

The hotter, the better. According to the Italian study, mild or not at all hot chili peppers had no favorable effects.

The US study involving 16,179 participants, found that chili eaters had 12% less risk of dying prematurely compared to those who did not. The period of this study over 19 years.

The Chinese study published in 2015, observed 487,375 participants for seven years, found that people who consumed spicy food daily reduced the risk of premature death by 14% compared to the ones eating hot food less than once a week.

Hot Chili peppers seem to have many beneficial effects. Also, the 2013 study of mice models suggests reduced non-alcoholic fatty liver disease.

These studies show a correlation between the mortality of chili lovers and chili despisers. The keyword here is 'correlation.' We need to be careful to draw any definite conclusions. Although these studies comprise several thousands of people, studies like this cannot unambiguously show causation. That is the cause and effect relationship.

Spicy foods as a sexual stimulant

For a long time, people have believed hot food to be a sexual stimulant. Capsaicin is the ingredient in peppers that is responsible for the spiciness. The molecular mechanisms causing reduced mortality are not known, but capsaicin, among others, stimulates the interesting molecule endothelial nitric oxide synthase (eNOS). Sildenafil, which is an ingredient in Viagra, also stimulates eNOS production.
