A new study being presented at this week's virtual meeting of the American Heart Association's Scientific Sessions 2020, will announce the surprising conclusion that eating chili peppers lengthens lifespans.
Previous research has shown that chili peppers may have an anti-inflammatory, antioxidant, anticancer, and blood-glucose lowering effect. A 2017 study that followed more than 16,000 Americans for almost 20 years found that those who ate the most chilies were 13% less likely to die prematurely.
In the new study, scientists looked at the health and dietary habits of over 570,000 people in the U.S., Italy, China, and Iran. Their conclusions were that people who regularly ate chili peppers had a:
- 25% reduction in all-cause mortality
- 23% reduction in cancer mortality
- 26% reduction in cardiovascular mortality
Senior author of the study, Bo Xu, who is a cardiologist at the Heart, Vascular & Thoracic Institute of the Cleveland Clinic in Cleveland, Ohio, told British newspaper The Independent: "We were surprised to find that in these previously published studies, regular consumption of chili pepper was associated with an overall risk-reduction of all-cause, cardiovascular disease, and cancer mortality."
The new study doesn't specify which types of chili peppers were eaten, or how much or how often they were consumed. As with the 2017 study and other previous studies, this one also did not demonstrate a causal link, merely the correlation between eating chili peppers and lower mortality. For example, the study did not attempt to answer the question of whether chili pepper-eaters had healthier lifestyles overall. However, if you want to get a jump start on improving your health, here's a quick guide to chili peppers.
Chili peppers are members of the nightshade (or Solanaceae) family of plants. This family includes edible plants such as tomatoes, potatoes, eggplant, bell peppers, and chili peppers. It also includes plants that have been used to derive the drugs scopolamine, which is used to treat motion sickness, atropine, which is used to regulate the heart rate, nicotine, and hyoscyamine.
Hyoscyamine is the active ingredient in ancient poisons, and some modern medicines. It is found in plants such as henbane, mandrake, angel's trumpets, jimsonweed, the sorcerer's tree, and deadly nightshade.
During the 1980s, the U.S. fell in love with the hot taste of chili peppers, which get their heat from the compound capsaicin. The heat of chili peppers is measured in Scoville Heat Units (SHU), and all mammals experience pain when eating chili peppers. However, birds do not, which means that they can also spread chili seeds.
The history of chili peppers
Chili peppers originated in Mesoamerica, which extends from Central Mexico to northern Costa Rica. Chili pepper plants had been domesticated by the Maya and Aztec peoples as far back as 5000 BCE and were used to flavor food as well as cure illness.
In 1492, when Christopher Columbus arrived in the New World, he was searching for a trade route to India, in part because people in Europe were clamoring for spices like black peppercorns, cloves, mace, and nutmeg, which were grown in India. When the Ottoman Empire shut off the most common trade routes, Spain's King Ferdinand and Queen Isabella sent Columbus to find another way.
This search for a route to India is why Columbus named the Caribbean islands the "Indies", and why the indigenous people were called "Indians". In fact, chili peppers were called "peppers" because their heat reminded Europeans of their much-loved black peppercorns.
While Columbus did bring some chili peppers back to Europe, it was really Portuguese traders who disseminated them worldwide. Special credit goes to the Portuguese explorer Vasco de Gama who in 1498, first sailed from South America around the Cape of Good Hope at the southern tip of Africa and on to India.
As soon as they got their hands on the chili plants, people living on the Indian subcontinent planted them and began including them in their cuisine. Chili peppers soon began making an appearance in other Asian cuisines.
What are chili peppers?
Chili pepper pods are actually berries, and they can be eaten fresh, roasted, dried, crushed into powder, or preserved by pickling or immersing in oil. Dried chilies can be reconstituted in liquid then ground into a paste.
The flavor of the popular chipotle is actually achieved by smoking and drying jalapeño peppers, and ancho, another popular chili, is actually dried poblano peppers. Poblano peppers are also commonly stuffed with cheese in the popular Mexican dish chile relleno. The popular Mexican sauce mole includes both ancho and chipotle peppers.
In fact, it's not just Mexican cuisine that frequently utilizes chili peppers around the world. In Italy, puttanesca and arrabbiata sauces both use chili peppers. In Hungary, paprika is made from dried chili peppers. Indian curries often include either fresh or dried chilies, and Caribbean jerk chicken is made with the super spicy Scotch bonnet chili.
Many Chinese dishes utilize oil fried dried chilis. In Thailand, chili pastes and sauces are made with fresh or dried chilies, while in Indonesia, the ubiquitous condiment sambal features dried chilies.
Around the world, thousands of varieties of hot sauces and pastes are made from chili peppers, including harissa from North Africa, Sichuan chili oil from China, and sriracha from Thailand.
