Want to Reduce Your Risk of Death by 12%? Eat More Chili Peppers
JalapeÃ±os are spicy chili peppers from the hot pepper family.
They are small, green or red in color and moderately spicy.
JalapeÃ±os are commonly used in Mexican cuisine but popular worldwide.
They're also packed with nutrients and have many health benefits.
This article reviews the benefits of eating jalapeÃ±os, discusses their possible side effects and suggests ways to add them to your diet.
1. High in Nutrients
JalapeÃ±os are low in calories and full of vitamins, minerals, fiber and antioxidants.
One raw jalapeÃ±o contains the following (1):
- Calories: 4
- Fiber: 0.4 grams
- Vitamin C: 10% of the RDI
- Vitamin B6: 4% of the RDI
- Vitamin A: 2% of the RDI
- Vitamin K: 2% of the RDI
- Folate: 2% of the RDI
- Manganese: 2% of the RDI
Like most fruits and vegetables, jalapeÃ±o peppers are a good source of fiber. One pepper provides 2% of the RDI for a person consuming 2,000 calories per day.
JalapeÃ±os also contain lots of vitamin C and vitamin B6.
One of the most unique compounds in jalapeÃ±os is capsaicin, an alkaloid that gives peppers their characteristic spicy quality and is responsible for many of their health benefits.
SUMMARY: JalapeÃ±os are low in calories and a good source of fiber, vitamin C and vitamin B6. They also contain a compound called capsaicin, which gives them their spice.
2. Can Promote Weight Loss
All of these factors help explain why regularly consuming chili peppers is associated with a significantly reduced risk of becoming overweight or obese over time (11).
While this research is promising, it is important to note that many of these studies investigated the effects of capsaicin or chili peppers in general, not just jalapeÃ±os.
SUMMARY: Research suggests that jalapeÃ±os and other spicy peppers may promote weight loss by boosting metabolism, increasing fat burn and reducing appetite.
3. May Fight Cancer
- Stopping the growth and division of cancer cells
- Slowing the formation of new blood vessels around cancer tumors
- Preventing cancer from spreading to other areas of the body
However, human studies have not replicated the anti-cancer benefits found in lab studies.
It also appears that dosage matters. While high doses of capsaicin appear to slow the spread of cancer, low doses may encourage spreading (23).
More studies are needed to determine how capsaicin and chili peppers influence the risk of cancer in humans.
SUMMARY: Preliminary studies suggest that capsaicin may help fight cancer in high doses, but more research is needed to determine whether this holds true in humans.
4. May Be Natural Pain Relievers
Capsaicin is an effective pain reliever when used externally (24).
It soothes pain by temporarily blocking pain receptors in the area where it is applied. At first, a burning sensation may be felt, followed by numbness and an absence of pain (25).
In one study, older adults with rheumatoid arthritis experienced a 57% reduction in pain after applying a capsaicin cream to their joints. This was significantly more effective than the placebo cream (29).
While capsaicin-containing lotions and sprays may be effective at treating pain, it is unclear whether eating jalapeÃ±os or applying them to the skin has the same effect.
SUMMARY: Products that contain capsaicin can help relieve pain when used topically, but it is unknown whether jalapeÃ±o peppers have similar effects.
5. Can Help Prevent Stomach Ulcers
Stomach ulcers can be caused by a number of factors, including (32):
- Growth of H. pylori bacteria within the stomach
- High levels of stomach acid
- Low blood flow to the stomach
- Taking too many NSAID pain relievers
- Drinking alcohol
While it is commonly believed that spicy foods like jalapeÃ±os can cause or aggravate stomach ulcers, research has shown this to be false (32).
In fact, the capsaicin in chili peppers may protect the stomach from developing ulcers in the first place.
It may have this effect by reducing stomach inflammation in people with H. pylori and even helping kill off the infection. However, it is not clear whether the amount of capsaicin in jalapeÃ±os is large enough to have this effect (33, 34, 35).
SUMMARY: While it is commonly believed that spicy foods can aggravate stomach ulcers, research suggests that capsaicin may protect the stomach from ulcers.
6. Help Fight Infections
Spices and herbs have long been used in cooking to help prevent spoilage and food poisoning (38).
Chili extracts can even stop cholera bacteria from producing toxins, potentially reducing the impact of this deadly foodborne disease (42).
However, it is important to note that all of these studies used chili extracts, not whole chilis, and were conducted in test tubes, not humans.
These early studies suggest that chili peppers may have strong antimicrobial properties, and future research is underway to determine if they may be used as natural preservatives or medicines.
SUMMARY: JalapeÃ±os and other spicy chilis contain compounds that can prevent the growth of harmful bacteria and yeasts that cause infectious diseases.
7. May Keep Your Heart Healthy
Some of the biggest risk factors for heart disease include diabetes, high cholesterol and high blood pressure.
Animal studies also suggest that capsaicin can help lower blood pressure by relaxing blood vessels, but there is no research to show whether this is true in humans (53).
Overall, preliminary research suggests that capsaicin and chili peppers may be beneficial for heart health, but more human studies are needed.
SUMMARY: Capsaicin and chili peppers have been found to have beneficial effects on blood sugars, cholesterol and blood pressure, but more human research is needed.
Possible Side Effects and Precautions
While eating jalapeÃ±os is associated with many promising health benefits, there are also some potential side effects.
The most common side effect is a temporary burning sensation of the mouth after eating. Depending on the spiciness of the chili, this reaction can range from mild to severe.
- Avoid scarring: Look for smooth jalapeÃ±o peppers without small brown lines, as scars indicate a spicier pepper.
- Use gloves: Wearing gloves when handling peppers can prevent transferring the spicy compounds to other sensitive areas of your body like your eyes.
- Remove membranes: Remove the white membranes inside the jalapeÃ±o before cooking with them, since the membranes have the highest concentration of capsaicin.
- Drink milk: If the burning sensation becomes too strong, drinking full-fat cow’s milk can help temporarily reduce the pain.
At least one study has found that capsaicin can worsen heartburn, so those with reflux may want to avoid jalapeÃ±os if they trigger symptoms (57).
People with irritable bowel syndrome may also experience unpleasant symptoms after eating spicy chilis, especially if they are not a regular part of their diet. Common side effects include abdominal pain, burning, cramping and diarrhea (58, 59, 60).
Additionally, dried peppers and spices can be contaminated with aflatoxin, a type of mold that grows on certain foods in certain conditions. Selecting irradiated spices may help reduce your exposure (61, 62).
SUMMARY: The most common side effect of eating jalapeÃ±os is a temporary burning sensation of the mouth, but simple steps can be taken to reduce it. Those with heartburn, IBS or aflatoxin sensitivity may want to avoid chili peppers to avoid symptoms.
How to Add Jalapenos to Your Diet
JalapeÃ±os can be eaten raw, cooked, smoked (also known as chipotle peppers), dried and even powdered.
Research shows that there is little to no loss of capsaicinoids during the drying process and only a moderate reduction from smoking or pickling, so it can be beneficial to consume jalapeÃ±os in all of their forms (63, 64).
JalapeÃ±os can be enjoyed:
- Raw in salads, salsas, chutneys or guacamoles
- Infused in spicy chili oils
- Cooked in main dishes
- Pickled, as a condiment
- Smoked, as chipotle peppers
- Blended into smoothies
- Baked into cornbread or egg dishes
- Stuffed with meat, cheese or pilafs
According to estimates, the average person living in the United States or Europe consumes roughly 1.5 mg of capsaicinoids per day.
Capsaicinoid consumption is much higher (between 25–200 mg per day) in countries like India, Thailand and Mexico, where cooking with chilis is more common (65).
Research shows that people who regularly eat chili peppers have a 12% reduced risk of death from any cause, even when controlling for other factors, so it may be beneficial for people to add more spicy peppers to their diets (66).
Generally, the spicier the pepper, the more health-promoting capsaicin it contains, but newer research also indicates a health benefit for non-spicy capsaicinoid compounds (67).
SUMMARY: JalapeÃ±os can be eaten in a variety of ways, including raw, cooked, smoked (also known as chipotle peppers), dried and even powdered.
The Bottom Line
JalapeÃ±os are a versatile and nutritious fruit that can be enjoyed in a variety of ways.
They contain capsaicin, a compound that likely accounts for many of their health benefits, including weight loss, pain relief, improved heart health and lower ulcer risk.
While safe for most, they can cause a temporary burning sensation of the mouth and uncomfortable intestinal side effects in some.
If you enjoy spicy food and do not experience any side effects, jalapeÃ±os can be a healthy addition to your diet.
