Frequently Asked Questions

What is the most important thing on a nutrition label?

The serving size is the most important element because all other numbers are based on it. Many packages contain multiple servings, so if you eat the whole package, you must multiply all values by the number of servings.

What does %DV (Daily Value) mean?

Daily Value percentage shows how much a nutrient in one serving contributes to a daily diet based on 2,000 calories. 5% DV or less is considered low, while 20% DV or more is considered high. Use this to quickly assess if a food is high or low in specific nutrients.

Why are ingredients listed in a specific order?

Ingredients must be listed in descending order by weight. The first ingredient makes up the largest proportion of the food. If sugar or an unhealthy ingredient appears in the first three ingredients, the product may not be as healthy as it appears.

How do I identify hidden sugars on labels?

Sugar has over 50 different names including high fructose corn syrup, dextrose, maltose, sucrose, agave nectar, and rice syrup. Look for words ending in "-ose" and any type of syrup. The "Added Sugars" line shows sugars not naturally present in the food.
