Q: What is the history of nutrition labeling on foods?
Before the 1960s, little if any nutrition information was present on food packages. Between the mid-1940s and 1960s, the food was considered “for special dietary uses” if calories or sodium values were listed.
More processed food (mixes, etc.) appeared in grocery store shelves in the 1960s. As nutrition researchers linked diet with various diseases, a need for informing consumers emerged. By 1973, many food packages showed calories, protein, carbohydrate, fat and percent of the daily recommendation for vitamins A, C, thiamin, riboflavin, niacin, and the minerals calcium and iron.
Two key reports regarding diet and health appeared in the late 1980s. In response, the Nutrition Labeling and Education Act of 1990 was passed and covered foods overseen by the Food and Drug Administration. By 1994, consumers began seeing Nutrition Facts labels on most foods.
Q: Did any changes occur on the 1994 Nutrition Facts labels before 2020?
“Trans fat” was added to nutrition labels in 2006. Trans fats are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid at room temperature. Trans fats may raise your bad (LDL) cholesterol levels and lower your good (HDL) cholesterol levels. Increased cholesterol buildup, or plaque, increases your risk of developing heart disease.
Q: What are the key changes to the Nutrition Facts label?
The number of calories per serving is the largest item on the label. Calories from fat is not on the label. You will note that serving size is in a larger, bolder font to attract your attention. Serving sizes were updated to be more realistic to what people actually eat. For example, a serving of cereal is now 1 cup, where it used to be ¾ cup.
Calcium and iron values remain on labels, but vitamins A and C are not required on Nutrition Facts labels. Most people meet the daily recommendations for these vitamins. Potassium and Vitamin D now appear on most labels (unless the package qualifies for simplified labeling).
“Added sugar” now is required on labels. Added sugars are sugars not present naturally in the food. “Total Sugars” includes natural sugars such as lactose in milk plus added sugar such as corn syrup.
Although the example labels are for the same food, you will note that the Percent Daily Value (%DV) differs in some cases. The %Daily Value (DV) shows how a serving of the food contributes to your daily diet. As shown in Table 1, some daily values were updated to reflect current nutrition research.
