Evidence: Strong
Key takeaways
- Start with the serving size. Every number on the label depends on it.
- Use % Daily Value as a quick guide: 5% or less is low, 20% or more is high.
- Look for more fiber and less added sugar, sodium and saturated fat.
- Then flip to the ingredient list: shorter lists of recognizable ingredients usually mean less processing.
You don’t need a nutrition degree to shop smarter. Once you know where to look, you can read a food label in about a minute and tell whether a product fits what you want. Here’s the fast, five-step method we use, based on the FDA’s own guidance.
Step 1: Check the serving size (5 seconds)
Every number on the Nutrition Facts panel is for one serving, and the serving size is often smaller than what people actually eat. If a bag of chips lists 2.5 servings and you eat the whole bag, multiply everything by 2.5.
Step 2: Glance at calories (5 seconds)
Calories tell you how much energy is in one serving. They matter, but they don’t tell you about quality, so don’t stop here.
Step 3: Use the % Daily Value shortcut (15 seconds)
According to the FDA, the % Daily Value (%DV) shows how much a nutrient in one serving contributes to a total day’s diet. The quick rule: 5% DV or less is low, 20% DV or more is high.
- Aim high (20%+) for dietary fiber, vitamin D, calcium, iron and potassium.
- Aim low (5% or less) for saturated fat, sodium and added sugars.
Step 4: Find the Added Sugars line (10 seconds)
The label lists Added Sugars on its own line, separate from total sugars. The FDA’s Daily Value for added sugars is 50 grams. Natural sugars in plain milk or fruit aren’t counted here, so this line shows what was added during processing. Learn the many names sugar hides behind in our guide to hidden sugar on labels.
Step 5: Read the ingredient list (25 seconds)
Ingredients are listed by weight, from most to least. A few quick checks:
- What’s first? The first few ingredients make up most of the product.
- How long is the list? Long lists full of ingredients you wouldn’t cook with often signal an ultra-processed food.
- Any additives you avoid? Look for synthetic dyes like Red 40, sweeteners, or “fragrance” in non-food products.

Why we rated this “Strong”: This method follows the FDA’s official guidance for using the Nutrition Facts label, and the nutrients to limit or seek out reflect long-standing dietary recommendations. How we rate evidence
Ignore the front of the package
Claims like “made with real fruit,” “lightly sweetened,” or “natural” are marketing. The Nutrition Facts panel and ingredient list are where the facts are. See what “natural” on a label really means.
Cleaner swaps to try

- Breakfast: cereals with 3+ grams of fiber and low added sugar
- Snacks: options with short ingredient lists you recognize
- Sauces: compare brands for sodium and added sugar per serving
The bottom line
Serving size, %DV, added sugars, then ingredients. Practice it a few times and it becomes automatic. It’s the single most useful habit for choosing cleaner foods. More label skills in our Ingredient Decoder.
