Red Dye 40 Food Additives naturallivingtips 1

Food additives are substances that are added to enhance taste, appearance, and texture. It improves qualities, preserves the flavor and improves the safety of foods.

The most common type of food additives is High Fructose Corn Syrup (HFCS), Monosodium Glutamate (MSG), Sodium Nitrite, Sodium Benzoate, artificial food coloring and much more.

Also, the most common group of food additives are antioxidants, colors, sweeteners, flavors enhancers, preservatives, emulsifiers, and stabilizers.

The food additives can be natural, nature-identical or artificial.

  • Natural additives are naturally extracted from foodstuffs like fruits and vegetables. For example, beetroot bright purple color can be extracted to give color to processed foods like sweets.
  • Nature identical additives are man-made additives that are identical to natural additives. For example, benzoic acid is naturally available but it can also be synthetically made and can be used as a preservative.
  • Artificial additives are totally synthetically made and are not present in nature. For example, Azodicarbonamide, a chemical compound, synthetically made as a food additive, is used as a flour bleaching agent and an improving agent.

You should know that food additives and unhealthiness are interrelated to each other. On average 60% of the average American diet contains chemically added processed foods.

While the worst ingredient in foods that are sold in the U.S are banned in other countries.

Mainly, 80% of all packed foods that are sold in American grocery stores contained bad ingredients. And, some of them are illegal in other countries.

Let’s look into the list of food additives and their side effects.
