Are you looking for a quick way to compare similar foods for their nutrient value? Then check the % Daily Values on today’s Nutrition Facts labels.
The % Daily Values (% DVs) are the recommended amounts of certain nutrients that you should eat each day to stay healthy. These percentages are nutrient reference values of foods, and they show how foods fit into your overall daily diet.
Sample Label for Macaroni & Cheese:
Serving Size 1 cup (228g)
Servings Per Container 2
Amount Per Serving
Calories from Fat 110
Note: The % DV column doesn’t add up vertically to 100%.
You do not need to know how to calculate percentages to use the % Daily Values, because the label does the math for you. It helps you interpret the numbers (written on the left in grams and milligrams) by putting them all on a 0-100% scale for the day. For example, the macaroni and cheese provides 12g of total fat, which is 18% of the daily maximum recommended amount of 65 grams, based on a 2,000 calorie diet.
Daily Value can be compared to a fundraising level. The % Daily Value is how much is given toward a recommended level by eating one serving of a food.
Let’s say that you ate two servings rather than one serving of the food in the example above. You consumed double the amount of fat, or 40% of the recommended maximum level for the entire day. That leaves you with 60% of your fat allowance from all the other foods you eat that day, including snacks and drinks.
You can still eat a healthy diet by using the % DV as a guide and making dietary trade-offs throughout the day. For example, balance a high-fat food (unhealthy saturated or trans fat) with low-fat foods at other times of the day. In other words, choose a food with a high % Daily Value of that nutrient and several foods with a low % Daily Value. (e.g. 11 grams of fat, 3 grams of fat, 0 grams of fat)
Each nutrient is based on 100% of the daily requirements for that nutrient in a 2,000 calorie diet. You may need more or less than that amount, depending on your age, gender, and activity level.
Even if you don’t know how many calories you consume in a day, you can still use the % Daily Value as a general guide. It doesn’t matter whether you consume more or less than 2,000 calories daily.
These percentages show you whether the nutrients in a serving of food contribute a lot or a little to your daily intake. The fast way to determine which nutrients contribute a lot or a little to your daily recommended allowance is to use this guide:
Low % Daily Values: You should consume foods with 5% DV or less of these nutrients often:
*Total fat includes all types of fat.
Limit these nutrients, because recommended amounts are the maximums you should consume. Aim for % Daily Values that add up to 100% or less of these nutrients each day.
High % Daily Values: Eat plenty of foods that contain 20% DV or more of these nutrients:
Select foods totaling 100% or more of the Daily Values for these nutrients each day. Recommended amounts are the minimums you should consume.
Be aware that 100% Daily Value for some nutrients isn’t always the optimal amount for you. You may need more or less. For example, the % DV for calcium on food labels uses 1,000 milligrams for calculations. However, the Dietary Reference Intake (DRI) for calcium recommends an intake of 1,000 to 1,300 mgs per day, depending on gender and age.
Remember that you are aiming to reach 100% or more of the Daily Value for the vitamins and minerals in all the foods you eat. However, you should aim for 100% or less of the Daily Value for total fat, saturated fat, cholesterol and sodium.
The % DV makes it easy for you to compare one product or brand to a similar product. Just make sure that you are comparing similar serving sizes or weights (e.g. gram, milligram, ounces). Since the serving sizes are generally consistent for similar types of foods, you easily can see which foods are higher or lower in nutrients. However, some cereals are an exception.
Using the % DV, you quickly can distinguish one claim from another. For example, you don’t need to memorize definitions for nutrient claims such as "reduced fat," "light," "nonfat," "low fat," etc. To see which food product is lower or higher in a nutrient, just compare the % DV for Total Fat.
