The Percentage (%) Daily Value. The daily value is the amount of a nutrient obtained heating one serving of the product. The amount is given in a percentage based on a diet of 2.000 calories day. For example, if the packaged food has 3 grams of fat, the total fat from eating one serving is 5% of total fat that should be ingested in an entire day. Ingredients. The ingredients contained in a pack- aged food are listed on the label. The item that is in the largest quantity is listed first. For example, it a product lists flour first and water second, there is more flour than water in the product. Preservatives, or chemicals, are added to food to keep it fresh lon- ger, and artificial flavors and colors are often added to processed foods. ohy tain ends Cion the Fot and Cholesterol. Because it is important to eat a low-fat diet, nutrition labels list both the total amount of fat and the amount of saturated fat and trans fat per serving. Saturated fat comes from an animal source and contains more cholesterol than unsaturated fat, which comes from a vegetable source. The cholesterol content is also listed. Sodium. The amount of sodium per serving is listed. This category is especially important for patients on a sodium-restricted diet, such as those with cardiac disease and hypertension. Comparing Labels Look at some labels from snack foods that people eat when they want something crunchy and salty. Figure 33-8 shows labels from potato chips, pret- zels, and snack crackers. When comparing prod- ucts, compare equal amounts. These products list the serving as 30 or 28 grams. That is close enough to compare the labels. In reviewing these labels, note the amount of fat and saturated fat in each item. It might be assumed that potato chips, which are fried, would be high in fat. It may be surprising that the snack crackers have high fat content. Pretzels are the clear winner for a low-fat snack among these options. Although the labels show total fat and satu- rated fat, the amount of trans-fatty acids (TFA) is not listed. Previously, food labels included trans fats within the total fat amount. The FDA now requires the amount of TFA be listed in the label.
