Nutritional Label dont reach 100% total when adding all component?

3 min read

Asked by: Rhonda Lee

Why do the totals of the nutrients not add up to 100 g?

If you are asking why the number of grams of each substance doesn’t add up to 100g, then that’s because not all of the material in the food is accounted for. A large portion of the mass of food tends to be water, but water content is not disclosed on the label. Dried food still has water in it, just much less.

Why do nutrition labels not add up?

The more significant mistakes come from eyeballing portion sizes or estimating calories from foods eaten out. Plus, foods are only required to come within 20 percent of the calorie content listed on the label. This fact means they can contain as much as 20 percent over or under what you track.

Why is there a percentage (%) provided on the nutrition label?

That myth? The notion that we need 100% of our daily value — or Recommended Dietary Allowance (RDA) — of every vitamin and mineral to attain optimal health. As journalist Catherine Price explained in her recent book Vitamania, that simply isn’t so.

What does 100% DV mean?

When you get 100% of a nutrient’s Daily Value, it means that you are getting enough of the nutrient to meet the average daily need for a generally healthy adult. “100% DV” means that there is enough of the nutrient to cover the general biochemical need for that nutrient in the human body for one day.

  1. dividing the amount of a nutrient in a serving size by its daily value, then.
  2. multiplying that number by 100.
