You’ll find it in sauces, broths, snacks, fast foods, and even frozen meals. Its name might slip under the radar on ingredient labels, but its effects on the body are facing growing scrutiny.
We’re talking about monosodium glutamate (MSG), a popular flavor enhancer in the food industry, which many studies and personal accounts have linked to bothersome symptoms such as bloating, gas, and even persistent fatigue.
What is MSG?
Monosodium glutamate, labeled as E621, is a sodium salt of glutamic acid, an amino acid naturally present in many foods.
In food production, its key role is to intensify flavors, creating the savory “umami” taste that many people find appealing.
You can find MSG in:
- Instant soups
- Frozen dishes
- Bouillon cubes
- Salty snacks
- Processed sauces
- Seasoning mixes
- Processed meats
Although health authorities have generally approved its use, frequent consumption can trigger side effects in people who are sensitive to it.
