Is Spicy Food Bad or Good for You?

Spicy foods — the ones that make your mouth burn — tend to split people into three groups:
You either love them, avoid them, or just tolerate them.

For fans like Amanda Sauceda, RD, a registered dietitian, the heat from chili peppers makes meals more exciting. She even suggests that if you’re trying to cut down on salt, adding a little spice might help. But Amanda admits — like many others — she had to build her spice tolerance over time before she truly enjoyed it.

Why some people handle spicy foods better than others can come down to a few things:

• If they ate spicy food often as kids

Let’s dive into why spicy food burns, and whether it’s actually good (or bad) for you.

What Makes Spicy Food So Spicy?

The heat you feel comes from a compound called capsaicin, found in chili peppers.
When you eat something spicy, capsaicin binds to special pain receptors in your mouth and digestive system, says Amanda Sauceda. Your brain thinks you’re in danger — like touching something hot — and triggers a cooling response.

Connie Elick, RD, another dietitian, explains that you might:

• Start sweating

• Get a red, flushed face

• Tear up or have a runny nose

All these reactions happen because your body is trying to “flush out” what it sees as an irritant.

Is Spicy Food Bad for You?

Good news: just because your brain feels the burn, it doesn’t mean spicy food is actually hurting you.
In fact, capsaicin can have some surprising health benefits!

Potential Health Benefits of Eating Spicy Foods

1. Capsaicin Might Act as an Antioxidant
First, a quick science lesson:
Your body makes “free radicals” — unstable molecules that can damage your cells.
Antioxidants help neutralize those free radicals and protect your body.

Early research suggests that capsaicin has antioxidant properties, meaning it might help protect your cells and keep you healthy over time.
