Food additives have been used for a centuries. For example, vinegar and salt is used to make food look better, taste better, and last longer.
Today’s additives are artificial and questionable as to their safety. Now additives go by the name of aspartame, methanol, diketopiperazine, monosodium glutamate, etc.
These additives are difficult to pronounce and found in many processed foods. If you have any doubts or questions about an additive, research it. The Center for Science in the Public Interest has a great guide.
To be 100 percent safe, simply stick to unprocessed and plant-based foods. You can’t go wrong with ingredients like avocado, spinach, rice, beans and olive oil.
The Animaniacs do a good job explaining food additives.
