Every ingredient explainer and product breakdown on the site, in one place. Explainers are grouped by what the ingredient does; products are listed at the bottom.

Most packaged drinks and snacks run on about a dozen additives: three or four sweeteners, a handful of dyes, two preservatives, two acids, and caffeine. Learn those and you can read nearly any label. Each explainer below covers one ingredient — what it is, why it’s in the product, what the research says, where regulators have acted, and whether it belongs on your list of things to worry about. The product breakdowns apply the same method to a specific can or bag, line by line, with a verdict.

Sweeteners

The ingredient that matters most on almost every label, in two forms: sugar in its various names, and the artificial sweeteners that replace it in anything marked “zero.”

Colors and dyes

Purely cosmetic. Nothing tastes different without them, which is why every argument about them is really about whether appearance is worth any risk at all.

Preservatives and acids

The ingredients that keep a drink shelf-stable and give it bite. One of them is the most direct, well-documented harm in any cola.

Caffeine and taurine

What’s actually in an energy drink, separated from what gets the credit.

Questions and comparisons

The questions people actually type — one drink against another, a quick yes or no, or “which ones don’t have X” — answered from the labels, with the full breakdowns linked for the detail.

How to read any label in thirty seconds

  1. Ingredients are listed by weight. The first two or three are most of what’s in the package. If sugar, corn syrup, or dextrose is in the top three, that’s the story.
  2. Sweeteners tell you what kind of product it is. Sugar or corn syrup means calories; aspartame, sucralose, or acesulfame potassium means “zero” — and usually a preservative added to compensate.
  3. Colors are at the end. A name with a number (Red 40, Yellow 5, Blue 1) is a synthetic dye. “Caramel color” is a different thing with its own question.
  4. Phosphoric acid means cola; citric acid means everything else. Both are acidic enough to matter for teeth; phosphoric has the bone research.
  5. Check caffeine from all sources. Energy drinks are required to state it because guarana and tea extracts add caffeine the ingredient list doesn’t total for you.
  6. “Natural flavors” tells you almost nothing. It means plant- or animal-derived, not simple or disclosed.

Every post follows the same process: the label is photographed, each ingredient is checked against FDA and EFSA documents and the peer-reviewed research, and the sources are linked at the bottom. How we research →
