What you will learn about Reading Nutrition Labels With Confidence
The 7-day sprint
- What the Label Is Actually Telling You. The Nutrition Facts panel reports nutrients for one serving of the food, measured against a one-day reference diet, in a fixed order set by federal rule.
- Serving Size Is the Unit of Everything. Every number on the panel is per serving, so the serving size and the servings per container are the first two things you read, not the last.
- Percent Daily Value and the 5/20 Rule. The %DV converts grams, milligrams, and micrograms onto one 0 to 100 percent scale for a whole day, and 5 percent or less is low while 20 percent or more is high.
- The Three Nutrients to Get Less Of. Saturated fat, sodium, and added sugars are the limit list, and the label gives you a Daily Value ceiling for each.
- The Nutrients to Get More Of, and the Ones With No %DV. Dietary fiber, vitamin D, calcium, iron, and potassium are the aim high nutrients, while trans fat, total sugars, and usually protein give you grams instead of a percentage.
- The Ingredient List and the Nine Allergens. Ingredients are listed in descending order by weight, and the nine major food allergens must be named in plain language every single time they are present.
- Front-of-Pack Claims and the Head-to-Head Comparison. Front-of-pack words like low sodium, good source, light, and reduced have legal definitions, but they are set on a reference amount that may differ from the serving size, so the panel always gets the final word.
The 80/20: the 7 concepts that matter most
- Read serving size and servings per container first
- The 5/20 rule for percent Daily Value
- Know the limit three and the aim-high five
- Added sugars sits inside total sugars
- The ingredient list is ranked by weight
- Front-of-pack claims are legal terms, not opinions
- Compare like with like, and use grams when %DV is missing
The core idea, explained like you are 5
Every number on a nutrition label is stated per serving and scored against one whole day of eating, so serving size and percent Daily Value are the two keys that unlock the entire panel.
Then the quiz and the ladder
10 questions that correct you when you are wrong, and beginner, intermediate, advanced levels, each with a practical exercise.
