FDA food labeling, explained

Plain-English, FDA-sourced guides to the Nutrition Facts label, serving sizes, and the labeling rules that matter to small food businesses. Each one links straight to the tools that do the work.

Label basics

How to read a Nutrition Facts label

The Nutrition Facts label packs a lot into a small box. Here is how to read every line — serving size, calories, the % Daily Value, and the nutrients to get more or less of — using the FDA's own guidance.

Added sugars on the Nutrition Facts label

Added sugars is one of the most useful lines on the modern label — and one of the most misunderstood. Here is what it counts, how it differs from total sugars, its Daily Value, and why honey and maple syrup get a special rule.

FDA Daily Values: the full reference table

The % Daily Value on every food label is calculated against a fixed set of reference amounts: the FDA Daily Values. Here is the complete table for adults and children over 4, what each value means, and what the 2016 update changed.

What 'gluten-free' means on a label

'Gluten-free' is a voluntary claim, but one with a precise FDA definition behind it. Here is exactly what it means, the 20-ppm threshold, and why 'wheat-free' is not the same thing.

'Natural' vs. 'organic' on food labels

'Natural' and 'organic' sound similar but mean very different things on a label — one is barely defined, the other is tightly regulated. Here is what each actually tells you.

Trans fat, '0 g,' and the PHO removal

Trans fat is the one nutrient the label tells you to keep as low as possible — and the one where '0 g' can mislead. Here is how the rounding works, why there's no %DV, and how the FDA pulled artificial trans fat from the food supply.

Food date labels: 'best by,' 'use by,' 'sell by'

Most people think food date labels are a federal safety rule. With one exception, they're not — they're voluntary, inconsistent, and mostly about quality, not safety. Here is what each phrase really means.

'Product of USA' and country-of-origin labels

'Product of USA' on a pack of meat used to mean surprisingly little. A USDA rule that took effect in 2026 changed that — but it's voluntary, and it doesn't tell you the origin of every product. Here is what the label now means.

Front-of-package labeling (proposed)

The FDA has proposed putting a small nutrition summary on the front of most food packages. It could change how you shop at a glance — but as of now it's a proposal, not a requirement. Here is what's on the table.

Compliance

Nutrition labeling for small food businesses

If you make and sell packaged food, the first question is simple: do you legally need a Nutrition Facts label? This guide walks through the FDA requirement, the two small-business exemptions, the claims that void them, and what you still have to put on the package either way.

Serving sizes and RACC, explained

One of the most misunderstood parts of a food label is the serving size. It is not a marketing decision — it is set by an FDA reference amount called the RACC. Here is how it works, and why getting it wrong is a common labeling violation.

Allergen labeling and the 9 major allergens

U.S. law requires packaged food to clearly declare nine major allergens. Here is the full list — including sesame, the newest addition — how the law (FALCPA and the FASTER Act) works, and exactly how allergens must appear on a label.

Nutrient content and health claims, explained

'Low fat.' 'Good source of fiber.' 'May reduce the risk of heart disease.' Every nutrition-related claim on a food label is regulated, and using one without meeting the FDA's definition is a misbranding violation. Here is how the two main claim types work.

The rest of the food label: ingredients, identity, and net quantity

The Nutrition Facts panel gets the attention, but several other things are mandatory on a packaged food label. Here is how to get the statement of identity, net quantity, and ingredient list right — the parts even a Nutrition-Facts-exempt business still has to include.

Supplement Facts vs. Nutrition Facts

Dietary supplements don't use the Nutrition Facts panel — they use Supplement Facts, under different FDA rules. Here is when each applies, how the panels differ, and the claim rules unique to supplements.

Dual-column labels: when and why

Some packages show two columns of nutrition — per serving and per container. That isn't a design choice; it's an FDA rule tied to how much of the RACC the package holds. Here is exactly when dual-column labeling kicks in.

Menu labeling: calories on chain menus

If you've noticed calorie counts on chain-restaurant menus, that's a federal rule — not a courtesy. Here is who has to post them, what else they must disclose, and how vending machines fit in.

The updated 'healthy' claim

In 2024 the FDA rewrote what 'healthy' means on a food label for the first time since 1994. The new rule shifts from single-nutrient math to food groups — and it changes which foods can wear the word.

FDA or USDA: which agency regulates your food label

Before you design a single label, you need to know which federal agency regulates your product — because the FDA and USDA don't just have different rules, they have different processes. Most packaged foods answer to the FDA. But add enough meat or poultry and your product crosses into USDA territory, where labels must be approved before you can sell.

Bioengineered (BE) food disclosure, explained

The label term 'bioengineered' replaced the old patchwork of state GMO-labeling laws. Since January 1, 2022, the USDA's National Bioengineered Food Disclosure Standard has required food companies to disclose when a product contains bioengineered ingredients. Here's who it applies to, how to disclose, and who's exempt.

Cottage food laws: selling homemade food legally

If you want to sell cookies, jam, or granola made in your own kitchen, cottage food laws are what make it legal. They're a state-by-state framework — not an FDA program — so the details vary, but the shape is remarkably consistent. Here's what qualifies, what your label must say, and where the limits are.

How to write a compliant ingredient list

The ingredient list looks simple — just list what's in the product — but it's one of the most-cited areas in FDA warning letters. The rules under 21 CFR 101.4 govern the order, the names, and a handful of details that trip up new brands. Here's how to get it right.

Nutrition label formats for small packages

The tall vertical Nutrition Facts panel doesn't fit on a stick of gum or a spice jar. FDA's rules under 21 CFR 101.9 give small packages alternative formats — and the very smallest can skip the panel altogether. Here's how package size decides your format.

Principal display panel and information panel, explained

FDA labeling isn't only about which pieces of information you include — it's about where each one goes. The rules split your package into two regulated zones: the principal display panel and the information panel. Put the right element in the wrong place and it's a violation. Here's the map.

Do alcoholic beverages need a Nutrition Facts label?

Ever wonder why your beer has no Nutrition Facts panel but a hard seltzer might? Alcohol sits under a different regulator than food. Most alcoholic drinks answer to the TTB, not the FDA — but an important slice falls under FDA rules and does need a Nutrition Facts label. Here's the split, and the change that may be coming.
