General education about U.S. FDA food labels, not personal medical advice or a compliance checklist. All example numbers and ingredient lists on this page are invented for teaching, not measured products. Photos illustrate food categories; they do not establish nutrition. Your needs may differ, especially for diabetes, kidney disease, pregnancy or childhood. Follow your care team’s guidance.
Here’s what to look for—and why each part matters. Start at the top before looking down the right-hand percentage column.
Ingredients: Whole grain oats, wheat bran, sugar, salt
How many servings are in the package.
This matters because… One package is not always one serving. A family bag, can or bottle may contain several.
Here’s what to look for: Eating two servings? Multiply every nutrient and the calories by two.
The labeled amount, shown in a familiar measure and grams or milliliters.
This matters because… Serving size reflects what people typically eat or drink—not a recommendation. Every number below uses this amount.
Here’s what to look for: Match the portion first. A tiny serving can make a product look lighter than it really is.
The energy in one labeled serving.
This matters because… They help you understand portion impact, but they cannot tell you everything about a food’s quality.
Here’s what to look for: FDA’s teaching guide calls 100 calories moderate and 400 or more high for an individual packaged food. These are not personal targets.
How much a serving contributes to a daily nutrient reference amount.
This matters because… 5% DV or less is low; 20% DV or more is high. The footnote uses a 2,000-calorie reference, not everyone’s calorie needs.
Here’s what to look for: For nutrients to limit, lower often helps. For fiber, a higher percentage may be useful. A percentage is not a personal prescription.
All fat in a serving, including saturated, trans and unsaturated types.
This matters because… Fat adds energy. The type of fat matters as well as the total.
Here’s what to look for: Look at saturated fat too; a food rich in unsaturated fat is not automatically a weaker choice.
A fat found in foods such as butter, fatty meats and some dairy products.
This matters because… Limiting saturated fat is part of heart-conscious eating patterns.
Here’s what to look for: Compare similar products and choose less saturated fat when practical.
A separate fat line without an established %DV.
This matters because… Less than 0.5 g per serving may round to 0 g. Naturally occurring trans fat is still possible.
Here’s what to look for: Partially hydrogenated oils are no longer generally recognized as safe in U.S. foods. Check ingredients where relevant; 0 g is not proof of absolute zero.
Dietary cholesterol, measured in milligrams (mg).
This matters because… Some people monitor it with their care team. Do not judge heart-health fit by this number alone.
Here’s what to look for: Consider saturated fat and the whole eating pattern alongside cholesterol.
A mineral listed in mg—not the weight of salt.
This matters because… Bread, soup, sauces, condiments and frozen meals can contribute more than expected.
Here’s what to look for: The general label DV is 2,300 mg. A soup at 800 mg is about 35% DV for one serving, and twice that for two.
The big picture: starches, dietary fiber and sugars are included here.
This matters because… For blood-sugar awareness, portion and total carbohydrate matter—not added sugar alone.
Here’s what to look for: Use your care team’s approach to carbohydrate. Do not assume a low-sugar product is automatically a personal diabetes fit.
A carbohydrate found in foods such as whole grains, beans, vegetables and fruit.
This matters because… Fiber is generally a nutrient to get more of and can support a satisfying eating pattern.
Here’s what to look for: The general label DV is 28 g. Compare fiber across similar portions.
Naturally occurring sugars plus added sugars.
This matters because… Milk and fruit can contain sugar even when none is added. Total sugars has no established %DV.
Here’s what to look for: Read the added-sugars line underneath. Do not add those grams to total sugars again.
Sugars added during processing or preparation, including honey or syrups used to sweeten foods.
This matters because… Two products can have similar total sugar but very different amounts of added sugar.
Here’s what to look for: The general label DV is 50 g. “Includes 10 g Added Sugars” means those 10 g are already inside the total sugars.
The grams of protein in one serving.
This matters because… It can help you compare yogurt, cereal, breads, snacks and meal options for balance.
Here’s what to look for: A %DV is often not shown on ordinary adult food labels. Its calculation involves protein quality, so grams are the practical comparison here.
Four required vitamins and minerals on current standard labels.
This matters because… They give a broader picture beyond calories. Other nutrients may appear too.
Here’s what to look for: Not every food must be high in every nutrient. Kidney-related potassium limits need personal guidance.
Explains how a serving contributes to a daily diet and mentions 2,000 calories.
This matters because… It provides context for the percentage column.
Here’s what to look for: Label reference amounts are not individualized recommendations. There is no %DV for calories, total sugars or trans fat.
A label only makes sense if you first know the serving size. Check the number of servings in the container, then think about the amount you will actually eat.
Our teaching cereal has eight 1-cup servings. Two cups mean twice the calories, sodium, carbohydrate, fiber, sugars and protein—not twice the serving size written on the package.
5% or less is low. 20% or more is high. In between is neither.
Low %DV
High %DV
Use the guide to compare nutrients, not to grade an entire food. Lower sodium or saturated fat may help a goal; higher fiber may be useful. The same percentage means different things for different nutrients.
A quick glance can tell you a lot, but calories alone miss fiber, protein, fat quality, sodium and added sugars. Foods with different textures and portions are not always meaningful direct comparisons.
Generally, ingredients appear in descending order by weight, from most to least. This does not tell you exact percentages. The first few ingredients offer useful clues.
For allergies, check the ingredient list and any “Contains” statement each time. The nine major U.S. allergens are milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and sesame. Advisory “may contain” statements are voluntary; their absence is not a safety guarantee.
These unbranded food photos and mock label formats explain what makes each package tricky. Real packaging may differ.
The familiar vertical panel uses one labeled serving. The large calories line and right-hand %DV column help you scan.
Some packages show per serving and per package or unit. Use the column matching the amount eaten; not every multi-serving food requires both.
Check whether the whole bottle is one serving. A bottle that looks single-use can still need a closer look.
Space-saving tabular or linear formats may look different. Read carefully for portion and omitted lines; do not assume an absent value means zero.
A serving is not the entire family bag or box. Count the portions actually eaten.
Some trays are one serving; others contain more. Check sodium and saturated fat alongside protein and fiber.
Pure single-ingredient sugars and syrups have a special FDA format: added-sugars %DV is still shown, but grams need not appear in the usual “Includes” line. An explanatory footnote may be used. This does not mean no added sugar.
Plain milk-based yogurt can contain natural milk sugar. Flavored versions may add sugar; check both sugar lines.
One slice versus two slices changes the basis. Whole-grain claims do not replace the fiber and sodium numbers.
A can may contain two or more servings. Check whether figures are for condensed or prepared soup.
A small bag is not always one portion. Bars and crackers vary in fiber, sodium and added sugar.
Cup measures and gram weights vary. Check whether a second column adds milk; compare cereals on the same basis.
Start with serving size. Then use several numbers together, rather than searching for one perfect food.
This is one of the biggest surprises: bread, sauce or a frozen meal may contribute sodium without tasting especially salty.
In the teaching soup comparison, 800 mg per cup is about 35% DV; 350 mg is about 15% DV. The second is lower, but not “low” by the 5% DV guide.
Naturally present sugar in milk or fruit appears in total sugars. Added sugars are included within that total, not stacked on top of it.
If a yogurt lists 20 g total sugars and includes 12 g added sugars, the total is still 20 g—not 32 g. The remaining 8 g is not classified as added in this teaching example.
Whole grains, beans and fruit can provide fiber. Packaging color and words such as “grain” do not tell you the grams.
Yogurt, eggs, lentils and nuts illustrate different protein foods, not measured equivalents. A label makes it easier to compare packaged options.
Once you know this sequence, comparing products gets much easier. If servings differ, compare a common amount or the portion you intend to eat.
All comparisons are invented teaching examples. Each pair uses the same weight and intended portion.
At 40 g per slice, Bread B has 90 mg less sodium, 2 g more fiber and 2 g less added sugar. It is a stronger fit for these goals; check actual labels and allergens.
Bread A · soft multigrain
Ingredients: Enriched wheat flour, water, sugar, whole wheat flour, yeast, salt
Bread B · whole wheat
Ingredients: Whole wheat flour, water, yeast, sunflower oil, sugar, salt
At 170 g, plain Yogurt B has 0 g added sugar and 17 g protein. Its 6 g total sugars is not the same as added sugar.
Yogurt A · sweetened
Ingredients: Cultured low-fat milk, sugar, strawberries
Yogurt B · plain
Ingredients: Cultured nonfat milk
At one cup, Soup B has 450 mg less sodium. Even that lower amount is about 15% DV—not “low” by the 5% guide.
Soup A · regular
Ingredients: Water, tomatoes, cream, wheat flour, salt, sugar
Soup B · lower sodium
Ingredients: Water, tomatoes, beans, olive oil, onion, salt
At 40 g, Cereal B offers 4 g more fiber and 9 g less added sugar. The calorie difference alone would miss most of this story.
Cereal A · sweet crunch
Ingredients: Corn flour, sugar, salt
Cereal B · oat cereal
Ingredients: Whole grain oats, wheat bran, sugar, salt
For 30 g, Crackers B provide less sodium and more fiber. “Six crackers” only compares fairly here because the weights also match.
Crackers A
Ingredients: Enriched flour, oil, salt, sugar
Crackers B
Ingredients: Whole wheat flour, sunflower oil, salt
For 125 g, Sauce B has 340 mg less sodium and no added sugar. Tomatoes still contribute naturally present sugar.
Sauce A
Ingredients: Tomatoes, sugar, oil, salt
Sauce B
Ingredients: Tomatoes, onion, olive oil, garlic, herbs, salt
For equal 300 g trays, Meal B has less sodium and saturated fat with more fiber and protein. Personal calorie and carbohydrate needs still matter.
Frozen meal A
Ingredients: Pasta, chicken, cream, cheese, salt
Frozen meal B
Ingredients: Brown rice, chicken, broccoli, beans, olive oil, salt
A quick scan, then slow down if something needs a closer look.
Check the portion before choosing the product.

A stronger choice is a better fit for a particular goal, not a perfect food. Different products can suit different needs. The mock comparisons below show tradeoffs without advertising brands.
A label is a comparison tool, not a diagnosis or a personal meal prescription. Low added sugar alone does not prove a food is diabetes-friendly.
For blood-sugar planning, look at total carbohydrate for the portion you will eat. Your care team may help you balance meals, medication and personal carbohydrate goals. For kidney disease, sodium, potassium and protein may need tailored guidance.
Reading a nutrition label is not about perfection. It is about knowing more, comparing more wisely, and making choices that better support your goals. With Healthy Heart Choices, every label becomes another opportunity to choose with confidence.
