Nutritionally, peppers vary depending on the variety and stage of maturity. In general, all peppers are a good source of vitamin A and C; the red ones are bursting with these two antioxidants. Antioxidants are a group of nutrients that neutralize free radicals in the body fluids reducing the risk of disease.
Free radicals are naturally produced when the body uses oxygen. Unless they are neutralized, they cause cell damage, which may lead to health problems such as arthritis, heart disease and cancer. A single raw red pepper, sweet or hot, can meet the daily requirements for two important antioxidants, vitamin A and C.

Probably not, according to recent studies. A common concern is that hot peppers or other spicy foods cause ulcers, but there's no evidence that they do. Studies of areas where hot peppers are used extensively in cooking, such as Brazil and Thailand, have found no higher incidence of stomach ulcers among their populations. And in a study conducted at a Veterans Administration hospital, researchers ground up about an ounce of jalapeno pepper and injected it directly into the stomachs of volunteers. Follow-up observation showed no damage to their stomach linings. Neither do hot peppers aggravate or cause haemorrhoids as has often been claimed, since capsaicinoids, the 'hot' substance, are broken down before they reach the lower intestine.
"Several medical studies have concluded that hot peppers and
other spicy foods do not cause ulcers.
Nor do hot peppers cause haemorrhoids, as has often been claimed"...
In the Jan/Feb 2000 issue of Chile
Pepper magazine, Dave Hirschopf, maker of Dave's Insanity sauces, wrote an
interesting article on 'Substance P'. This is the chemical that may lead to the
desensitisation of your reaction to hot peppers, i.e. the more you eat hot
peppers, the less the effect they have on you. Substance P is a
neurotransmitter, discovered in 1931 by Swedish scientists, that is thought to
transmit pain signals, and well as other functions. It is also a neurokenin,
known as NK1. As well as being found in nerve cells, substance P can be found in
the brain, spinal cord and intestines.
The cause and effect sequence is thought to be as follows: You eat a hot chile
pepper, the capsaicin in the pepper causes the nerve cells in the spinal cord to
release substance P, this informs the brain that you are in pain. As you eat
more peppers, your nerve cells become hypersensitive to substance P and no
longer react in the normal way, i.e. your brain no longer gets the pain signals.
David Julius and Michael Caterina, of the University of California in San
Francisco, have found the protein ion receptor for capsaicin, the pungent
ingredient in hot chile peppers that causes painful heat sensation.
The protein, known as vanilloid receptor subtype 1 (VR1), is activated by
binding to capsaicin. High, painful temperatures work in a similar way and cause
the same sensation.
"In the same way that the study of morphine led to the discovery of nerve
pathways in the brain that suppress pain, we believe that our having found the
target of capsaicin activity will illuminate fundamental mechanisms of pain
production".
Julius says that the VR1 channel opens up when it is activated by hot peppers
and allows an influx of calcium and sodium ions to react to sensory nerve cells
called nociceptors. They send impulses about tissue damage to the pain
processing centres in the spinal cord and brain which cause the hot sensation in
the mouth. Hot temperatures that produce pain in humans produce the same
response.
It is worth noting that birds cannot taste the hotness in peppers and the fruit of the bird peppers are so small that they are often eaten whole. The bird’s gizzard breaks up the pods and the seeds pass through undigested and surrounded by a nice nitrogenous fertiliser. Mammals, on the other hand, are discouraged by the extreme hotness of the bird peppers, unless of course, they are Chile Heads!
Chile peppers are all-season foods: they warm you up in winter and cool you down in the summer. This correlates to the feeling of warmth when eating chillies. Hot foods do increase perspiration, which may be the underlying reason they are enjoyed in hot climates. So a sweat and possibly a brief increase in your metabolic rate won't influence weight loss either. The best contribution to weight loss is the flavours chillies can add to foods when the fat has been removed. Studies done in populations that use hot peppers consistently found that these people show no higher incidence of any gastrointestinal diseases. In fact, there are some areas where they exhibit some beneficial effects. The Capsaicin has been identified as an anticoagulant and could possibly aid in preventing a heart attack or stroke. Since 1982, there have been more than 2,000 scientific studies published describing the medicinal benefits of chillies. These include treatments for asthma, arthritis, blood clots, cluster headaches, shingles and severe burns.
It is believed that relief of PMS
can come from the Endorphin release after eating chillies, although there is
certainly the possibility of other factors coming into play. Aside from the
documented physiological/psychological effects of endorphins, chillies are high
in compounds known as Bioflavonoids.
These compounds are powerful anti-inflammitories. Bioflavonoids are also noted
to help blood vessel walls strengthen and lessen bleeding. This could be another
source of the relief. Chiles are also cited by nearly every homeopathic and home
remedy book to be able to reduce inflammations. Chiles are believed by many
peoples to achieve this effect through a normalising of blood pressures and
blood flows in the body. Chiles are also noted to be relatively high in
magnesium. Some time ago, bananas were touted as the ultimate cure for PMS when
it was found that potassium helped to relieve the symptoms associated with PMS.
Magnesium comes from the same family on the periodic table and could potentially
mimic this effect.
