U.S. RDA stands for “United States Recommended Daily Allowances.” The U.S. RDAs were developed by the Food and Drug Administration (FDA) for its nutrition labeling and dietary supplement programs, and were derived from the Recommended Daily Dietary Allowances of the Food and Nutrition Board of the National Academy of Sciences. The U.S. RDAs represent amounts of protein, vitamins, and minerals that will fully satisfy a healthy adult’s daily needs for these nutrients. Many adults may need only three fourths of the U.S. RDA for several nutrients, and children may need only about one half. Thus the U.S. RDAs are only a guideline for good nutrition and are intended primarily for use in nutrition labeling.

The information given on nutrition labels will help you plan more nutritious meals, help you compare nutritive values of different brands, and help you in selecting foods for special diets.

Food Additives
A food additive is any substance added to foods during processing or packaging. Most additives are in chemical form, derived from natural sub stances. Food additives are nothing new. Salt and pepper have been used for centuries for the preservation of meat. Spices and herbs are also additives.

In order to be used as a food additive, a substance must be safe in the quantity used, it must perform its intended function, and it must not jeopardize the nutritional value of the food.

Without additives our foods would cost more and probably be less wholesome. Furthermore, the laws in the United States governing food quality and the use of food additives are the strictest in the world. Nevertheless, since some food additives remain insufficiently tested, many questions regarding their safety have yet to be answered.
