Shopping was easy when most food came from farms. Now, factory-made foods have made chemical additives a significant part of our diet. Most people may not be able to pronounce the names of many of these chemicals, but they still want to know what the chemicals do and which ones are safe and which are poorly tested or possibly dangerous.

A simple general rule about additives is to avoid sodium nitrite, saccharin, caffeine, olestra, acesulfame K, and artificial coloring. Not only are they among the most questionable additives, but they are used primarily in foods of low nutritional value.

Also, don’t forget the two most familiar additives: sugar and salt. They may pose the greatest risk because we consume so much of them. Fortunately, most additives are safe and some even increase the nutritional value of the food.
