Percent Daily Values (%DVs) are the percentage of the daily values found in a specific serving of a food and based on the Daily Value recommendations for key nutrients, and for a 2000 calorie diet. %DVs help you determine if a serving of food is high or low in a nutrient. Also, %DVs make it easier to compare the amount of nutrients in a food and know which nutrients contribute a lot or little to your daily recommended allowance.
