Nutrition Facts Label
Serving Size: The first place to start when you look at the Nutrition Facts label is the serving size and the number of servings in the package. Serving sizes are standardized to make it easier to compare similar foods; they are provided in familiar units, such as cups or pieces, followed by the metric amount, e.g., the number of grams. Keep in mind "How many servings am I consuming"?
Calories (and Calories from Fat): Calories provide a measure of how much energy you get from a serving of this food. Many Americans consume more calories than they need without meeting recommended intakes for a number of nutrients. The calorie section of the label can help you manage your weight ( i.e., gain, lose, or maintain.) The General Guide to Calories (40 Calories is low, 100 Calories is moderate, 400 Calories or more is high) provides a general reference for calories when you look at a Nutrition Facts label. This guide is based on a 2,000 calorie diet. Eating too many calories per day is linked to overweight and obesity.
The Nutrients: Look at the top of the nutrient section in the sample label. It shows you some key nutrients that impact on your health and separates them into two main groups (Limit, and Increase): 1. The nutrients listed first are the ones Americans generally eat in adequate amounts, or even too much. Limit these Nutrients. Eating too much fat, saturated fat, trans fat, cholesterol, or sodium may increase your risk of certain chronic diseases, like heart disease, some cancers, or high blood pressure. Health experts recommend that you keep your intake of saturated fat, trans fat and cholesterol as low as possible as part of a nutritionally balanced diet. 2. Most Americans don't get enough dietary fiber, vitamin A, vitamin C, calcium, and iron in their diets. Get Enough of these Nutrients. Eating enough of these nutrients can improve your health and help reduce the risk of some diseases and conditions. For example, getting enough calcium may reduce the risk of osteoporosis, a condition that results in brittle bones as one ages. Eating a diet high in dietary fiber promotes healthy bowel function. Additionally, a diet rich in fruits, vegetables, and grain products that contain dietary fiber, particularly soluble fiber, and low in saturated fat and cholesterol may reduce the risk of heart disease. You can use the Nutrition Facts label not only to help limit those nutrients you want to cut back on but also to increase those nutrients you need to consume in greater amounts.
Footnote: Note the * used after the heading "%Daily Value" on the Nutrition Facts label. It refers to the Footnote in the lower part of the nutrition label, which tells you "%DVs are based on a 2,000 calorie diet". This statement must be on all food labels. But the remaining information in the full footnote may not be on the package if the size of the label is too small. When the full footnote does appear, it will always be the same. It doesn't change from product to product, because it shows recommended dietary advice for all Americans--it is not about a specific food product. Look at the amounts in the footnote--these are the Daily Values (DV) for each nutrient listed and are based on public health experts' advice. DVs are recommended levels of intakes. DVs in the footnote are based on a 2,000 or 2,500 calorie diet. Note how the DVs for some nutrients change, while others (for cholesterol and sodium) remain the same for both calorie amounts.
Another way to see the Daily Values (DVs) relate to the %DVs and dietary guidance (depends on the label): For each nutrient listed there is a DV, a %DV, and dietary advice or a goal. If you follow this dietary advice, you will stay within public health experts' recommended upper or lower limits for the nutrients listed, based on a 2,000 calorie daily diet. 1. The nutrients that have "upper daily limits" are listed first on the footnote of larger labels and on the example above. Upper limits means it is recommended that you stay below - eat "less than" - the Daily Value nutrient amounts listed per day. For example, the DV for Saturated fat is 20g. This amount is 100% DV for this nutrient. The goal or dietary advice is to eat "less than" 20 g or 100%DV for the day. 2. Lower Limits Eat "at least."
The % Daily Values (%DVs): The %DV helps you determine if a serving of food is high or low in a nutrient. Note: a few nutrients, like trans fat, do not have a %DV--they will be discussed later. The label helps interpret the numbers (grams and milligrams) by putting them all on the same scale for the day (0-100%DV). The %DV column doesn't add up vertically to 100%. Instead each nutrient is based on 100% of the daily requirements for that nutrient (for a 2,000 calorie diet). This way you can tell high from low and know which nutrients contribute a lot, or a little, to your daily recommended allowance (upper or lower). The Quick Guide - 5%DV or less is low and 20%DV or more is high. This guide tells you that 5%DV or less is low for all nutrients, those you want to limit ( e.g., fat, saturated fat, cholesterol, and sodium), or for those that you want to consume in greater amounts (fiber, calcium, etc). As the Quick Guide shows, 20%DV or more is high for all nutrients.
Trans Fat: Experts could not provide a reference value for trans fat nor any other information that FDA believes is sufficient to establish a Daily Value or %DV. Scientific reports link trans fat (and saturated fat) with raising blood LDL ("bad") cholesterol levels, both of which increase your risk of coronary heart disease, a leading cause of death in the US. Health experts recommend that you keep your intake of saturated fat, trans fat and cholesterol as low as possible as part of a nutritionally balanced diet.
Protein: A %DV is required to be listed if a claim is made for protein, such as "high in protein". Otherwise, unless the food is meant for use by infants and children under 4 years old, none is needed. Current scientific evidence indicates that protein intake is not a public health concern for adults and children over 4 years of age.
Sugars: No daily reference value has been established for sugars because no recommendations have been made for the total amount to eat in a day. Keep in mind, the sugars listed on the Nutrition Facts label include naturally occurring sugars (like those in fruit and milk) as well as those added to a food or drink. Check the ingredient list for specifics on added sugars. For Example a plain yogurt may have 10g of sugars, while a fruit yogurt may have 44g of sugars in one serving. So look at the ingredient lists for the two yogurts. Ingredients are listed in descending order of weight (from most to least). Note that no added sugars or sweeteners are in the list of ingredients for the plain yogurt, yet 10g of sugars were listed on the Nutrition Facts label. This is because there are no added sugars in plain yogurt, only naturally occurring sugars (lactose in the milk). The fruit yogurt contained large amounts of corn syrup, and high-fructose. Other names for added sugars include: corn syrup, high-fructose corn syrup, fruit juice concentrate, maltose, dextrose, sucrose, honey, and maple syrup.
