Not everybody enjoys spicy food. This often comes down to where you grew up in the world. Many people were raised in cultures where hot chili peppers formed a core part of everyday meals. Yet even some who didn’t grow up eating spicy food have developed a real love for it. On the flip side, plenty of people avoid anything remotely hot altogether. Wherever you fall on that scale, research actually points to quite a few genuine health advantages that come with regularly eating spicy food.
So have you ever stopped to think about what’s actually going on inside your body when you eat something spicy? Read on to find out!
You may lose weight
Eating spicy food could help you shed pounds and keep them off. The key ingredient here is capsaicin, the active compound found in chili peppers that drives this effect.
This isn’t to suggest you can skip a caloric deficit entirely, but spicy food may give your metabolism a nudge, causing your body to burn through slightly more calories throughout the day.
A 2017 study concluded that capsaicin plays a meaningful role in human health, offering several advantages for metabolic function — particularly around weight reduction in people who are obese.
You may feel less pain
Under certain conditions, spicy food can actually act as a mild painkiller. Capsaicin is responsible here too. It’s thought to interfere with a brain chemical called substance P, which carries pain signals from nerve endings up to the brain.
Interestingly, a topical gel containing between 2.5% and 8% capsaicin has demonstrated real pain-relieving results. Studies have shown it works particularly well for osteoarthritis and has also shown promise in reducing nerve-related pain.
Daily ingestion may help prevent peptic ulcers
The idea that spicy food causes ulcers is widely believed but largely incorrect. The reality is actually the opposite — capsaicin can suppress acid production in the stomach.
Ulcers are more commonly triggered by things like chronic painkiller use or H. Pylori bacteria. Gastroenterologist Edwin McDonald points out that capsaicin has even been explored as a potential preventative measure for people regularly taking non-steroidal anti-inflammatory drugs.
It may boost your immune system
Spicy foods could give your immune system a real lift, largely because they’re packed with antioxidants that shield your cells from free radical damage — damage that has been linked to various chronic illnesses.
It’s one reason why former US Secretary of State Hillary Clinton reportedly made eating a hot pepper a daily habit. Food science professor John Hayes notes that certain compounds in chili peppers do appear to have a protective effect on overall health.
It may help fight cancer
One study found that capsaicin was able to destroy a significant proportion of prostate cancer cells in rodents while leaving healthy cells unharmed.
Though more investigation is still needed, a systematic review highlighted that combining capsaicin with other therapies showed particularly encouraging results for lung and prostate cancers, suggesting it may hold genuine therapeutic value.
You might live longer
There’s evidence to suggest that eating spicy food regularly could add years to your life. One large study found that frequent spicy food consumption was linked to lower overall mortality rates, even after accounting for other health risk factors.
Specifically, people who ate spicy food five to seven days a week showed a 14% lower relative risk of dying compared to those who consumed it less than once a week.
It may reduce your sugar cravings
Given that too much sugar is tied to a range of health problems, anything that curbs those cravings is worth paying attention to. After eating something spicy, sweet foods tend to lose their appeal — a bit like how orange juice tastes odd straight after brushing your teeth.
Swapping a sugary snack for something spicy could be an easy way to manage cravings. Dietitian Bonnie Taub-Dix has noted that patients often feel genuinely satisfied after eating something like chili sauce or jalapeño, saying it hits the spot for them.
It may help clear your sinuses
It’s no coincidence that spicy food often leaves you reaching for a tissue. Capsaicin works similarly to compounds found in many over-the-counter decongestants, and dietitian Cynthia Sass notes that the hotter the pepper, the stronger this effect tends to be.
On top of that, chili peppers are a solid source of vitamin A, which helps maintain healthy mucous membranes — your body’s first line of defense against invading germs.
It may help reduce inflammation
Thanks to capsaicin’s anti-inflammatory properties, eating spicy food on a regular basis may help bring down inflammation levels throughout the body.
One study even found that capsaicin’s anti-inflammatory effects were comparable to those of diclofenac (commonly known as Voltaren) in rat studies.
It may be beneficial for your heart
Hot peppers have been shown to lower levels of harmful LDL cholesterol while raising beneficial HDL cholesterol, which improves blood flow and lowers the risk of developing heart disease.
Sass also notes that capsaicin is currently under investigation for its potential in treating circulation problems, arterial hardening, and irregular heart rhythms.
It may change your palate
Eating spicy food every day can gradually shift your taste preferences, as your palate adapts to higher heat levels over time, making you more tolerant of spice.
That said, it can also affect how other foods taste. Overloading on spice may temporarily dull your ability to taste other flavors, making them seem flat or bland. So it’s worth showing some restraint with the hot sauce.
It may help ease constipation
One side effect of eating spicy food is that it tends to make you drink more water, which keeps you better hydrated and can help ease constipation symptoms.
It may make you rush to the toilet
However, for people with more sensitive digestive systems, this effect can go further. Spicy food can over-stimulate receptors in the colon, speeding up the entire digestive process as the body tries to protect itself.
Gastroenterologist Kenneth Brown explains that when this happens, the colon doesn’t get the chance to absorb water properly, which can result in a sudden and urgent trip to the bathroom.
It may aggravate gastrointestinal conditions
For those already living with digestive conditions, daily spicy food intake can make things worse. People managing Crohn’s disease, for example, are generally advised to steer clear.
It may aggravate heartburn
Similarly, anyone prone to heartburn or diagnosed with gastroesophageal reflux disease (GERD) will likely find that spicy food makes their symptoms flare up rather than settle down.
