Flavor enhancers are substances added to food to boost its taste without significantly changing its original flavor. Common examples include monosodium glutamate (MSG), yeast extract, and hydrolyzed vegetable protein. These ingredients work by intensifying the natural flavors of the food, making it more enjoyable to eat. They are often found in processed foods, snacks, and restaurant dishes. While flavor enhancers can make meals more delicious, some people may be sensitive to them or prefer to avoid them for health reasons. It's essential to read food labels and understand what you're consuming, especially if you have dietary restrictions or allergies.
