What really happens in your body when you eat spicy food?

A little curry that heats up a little, a hot sauce that sends shivers down your spine... And suddenly, your nose is running, your tongue is twitching, and your forehead is beading... So what exactly happens in your body when you eat spicy food? Is it good? Is it risky? Can it really "burn calories" as we often hear?

We've dug into all that for you! :)


The culprit: capsaicin

When it comes to the sensation of fire in the mouth, it's all down to a component found in chillies: capsaicin.

This little stuff activates your pain receptors, as if you'd just touched something hot... except there's no injury. Just a pungent illusion that makes your brain, mouth, sweat glands and sometimes even your emotions react!

The result? Sweat and heat!


The benefits of spicy food

1. Boosts metabolism

Capsaicin causes a slight rise in body temperature, which may help burn a few more calories. So no, chilli doesn't make you lose weight, but as part of a varied diet, it can give you a little boost!

2. It's a natural anti-inflammatory

Certain spice compounds, including capsaicin, have interesting anti-inflammatory properties!

3. It stimulates digestion

Spicy food stimulates gastric juices: basically, it gets your digestive system moving. But that's no reason to drown your dishes in harissa...

4. And it even helps you breathe!

Yes, the runny nose you get when you eat spicy food isn't just unpleasant: it also helps clear the airways.


What about the risks?

Eating spicy food doesn't hurt everyone... but it can sting a little more than expected for some:

  • Gastric irritation: if you have a sensitive stomach or gastritis, spicy food can make the discomfort worse.
  • Accelerated transit: no need to draw a picture, you know what we mean...
  • Mouth and throat on fire: some people react more strongly than others!
  • And beware of ulcers or certain digestive pathologies: it's best to speak to a professional if you have any doubts.

In short: spicy, but not too spicy.

Eating spicy food is good for you, it adds atmosphere to your meal and awakens your body and mind. But as with everything in the kitchen: balance is your best ally.

A little chilli, a pinch of curry, a few mustard seeds or a touch of ginger: test, dose, adjust according to your mood and sensations.

And above all: indulge yourself, without burning your taste buds in the process ;)
