Side-by-side differences between foods, varieties, formats and methods, with comparable data and the context needed to interpret it.
Calories on Nutrition Facts are tied to the labeled serving. If a package holds 2.5 servings and you eat all of it, the package contributes about 2.5 times the listed calories and nutrients unless a second column already shows per-container values.
Percent Daily Value turns grams and milligrams into context: it estimates how much one serving contributes to a standard daily reference. FDA’s quick guide is that 5% DV or less is low and 20% DV or more is high, but your personal needs can differ.
On U.S. food labels, “good source” and “excellent source” are regulated nutrient-content claims, not casual praise. A good source generally supplies 10–19% of the Daily Value for the named nutrient per reference amount, while high/excellent source generally begins at 20%.
“Low fat,” “reduced fat,” and “fat free” are regulated U.S. nutrient-content claims with different logic. Low and fat free use absolute limits; reduced fat compares a product with a reference version. None automatically means low calorie or nutritionally superior.
Low sodium, reduced sodium, and no salt added are not synonyms. One sets an absolute sodium ceiling, one requires a percentage reduction from a reference food, and one says salt was not added during processing. The Nutrition Facts milligrams show the actual amount you will eat.
MSG contains sodium because it is monosodium glutamate, but sodium makes up a smaller fraction of its weight than it does in table salt. Used to replace part—not necessarily all—of the salt in a savory recipe, MSG can preserve umami while lowering total sodium.
Whole grain describes the intact grain components—bran, germ, and endosperm—in their original proportions. Whole wheat is the wheat-specific version. So whole wheat is whole grain, but a whole-grain food can use oats, rye, brown rice, corn, or other grains instead of wheat.
“Multigrain” describes variety: more than one grain is used. “Whole grain” describes processing: bran, germ, and endosperm remain in the grain ingredient. A bread can be both, but multigrain on its own does not guarantee that any particular grain is whole.
USDA organic production excludes genetic engineering, but “organic” is a broader certified production standard. A non-GMO claim speaks to genetic engineering; by itself it does not tell you whether the food met USDA organic rules for certification, allowed inputs, or other production practices.
Erythritol, xylitol, and sorbitol are different polyols, not interchangeable versions of one ingredient. Erythritol contributes very little energy; xylitol is about as sweet as sugar, while sorbitol is less sweet and strongly humectant.
Replacing sugar can lower added sugar and sometimes calories, but it is not a one-function swap. Sugar also supplies bulk, holds water, promotes browning, affects spread, and keeps frozen desserts softer.
Coconut sugar may contain trace minerals and small amounts of plant compounds, but nutritionally it is still a concentrated added sugar. A teaspoon has roughly the same calories and grams of sugar as regular sugar.
