Reading Nutrition Labels
A quick glance at a few key spots on the label tells you what a package is really offering, so you can decide what to buy and what to use in your kitchen.

The Why
Why It Matters
Food packaging is designed to sell, but the label on the back is where you get the real information. Learning to read it puts you in charge, so you can choose foods that match what you actually want more or less of. Many whole foods, like fresh produce, barely need a label at all. It is the packaged food that needs a second look.
The Essentials
What to Know
Start with the serving size
Everything on the Nutrition Facts label, from calories to grams of sugar, is based on one serving. That is your reference point. It is worth checking, because a package can hold more than one serving, and the numbers you see may be for a smaller amount than you would actually eat. Serving size is a general measurement, not a rule about how much you should have.
Scan the numbers that matter to you
Read the ingredient list
Ingredients are listed by weight, heaviest first. The first one or two tell you what you are mostly eating. For more nutrient-dense picks, look for recognizable whole foods near the top. For less-processed picks, look for a short list of items you can actually pronounce.
The comparison
140 vs. 140 — one flavored, one plain
Two yogurts, same calories, same 150-gram pot. Redrawn from two retail containers, brands removed; the values are the label’s own and the pink marks are ours.
Flavored · 9 ingredients
Amount per serving: Calories 140, Total Fat 2.5g (3% DV), Saturated Fat 1.5g (8% DV), Trans Fat 0g, Cholesterol 15mg (5% DV), Sodium 75mg (3% DV), Total Carbohydrate 17g (6% DV), Dietary Fiber <1g (2% DV), Total Sugars 16g (Includes 10g Added Sugars, 20% DV), Protein 11g (22% DV), Vitamin D (0% DV), Calcium (10% DV), Iron (0% DV), Potassium (4% DV).
Ingredients: Cultured reduced fat milk, cane sugar, lemon pulp, water, fruit pectin, natural flavors, lemon juice concentrate, guar gum, turmeric (for color).
Plain · 2 ingredients
Amount per serving: Calories 140, Total Fat 8g (10% DV), Saturated Fat 5g (27% DV), Trans Fat 0g, Cholesterol 25mg (9% DV), Sodium 55mg (2% DV), Total Carbohydrate 5g (2% DV), Dietary Fiber 0g (0% DV), Total Sugars 5g (Includes 0g Added Sugars, 0% DV), Protein 14g (27% DV), Vitamin D 0mcg (0% DV), Calcium 180mg (15% DV), Iron 0mg (0% DV), Potassium 230mg (4% DV).
Ingredients: Grade A pasteurized skimmed milk and cream, live active yogurt cultures (L. Bulgaricus, S. Thermophilus, L. Acidophilus, Bifidus, L. Casei).
Neither pot is simply the better one: more sugar and more ingredients in one, more protein and more fat in the other. The label does not rank them; it lets you see the trade-off and choose. If you prefer the plain pot but not its taste, flavor it yourself: fruit or a drizzle of honey. Fruit’s sugars don’t count as “added”; honey’s do, and now the amount is your call.
Where the difference shows
Serving size: every number on the panel describes this amount. Both pots hold 150 g.
Added sugars: its own line, for sugar added in processing. Flavored: 10 g of 16. Plain: none of 5.
% Daily Value: 20% or more of a nutrient in one serving is a lot, 5% or less is a little (FDA). Added sugars on the flavored pot: exactly 20%.
The first two ingredients: listed heaviest first, so those two are most of what you are eating. Cane sugar is second of nine on the flavored pot.
Your Turn
Try This
Next time you shop, pull one packaged food you buy often and give its label a slow read. Notice the serving size first, then let your eyes travel to the numbers and ingredients that matter to you.
