How We Research a Post

Every FittBeat post follows the same process. It’s listed here so you can judge for yourself how much to trust what you read.

1. We start with the physical label

We buy the product and photograph the ingredient panel and nutrition facts. Ingredient lists on manufacturer websites and retailer listings are often out of date — formulas change, regional versions differ, and “zero sugar” variants get quietly reformulated. The label on the shelf is the source of truth, and the post states which size and flavor it reflects.

2. Every ingredient gets looked up individually

For each ingredient we check, in this order:

• The FDA’s food additive status and any current regulatory action (petitions, revocations, phase-outs)
• The European Food Safety Authority’s most recent scientific opinion, because the EU often reviews additives more recently and more strictly than the FDA
• Peer-reviewed research, with randomized controlled trials and meta-analyses weighted far above animal studies, cell studies, and observational data
• The manufacturer’s own stated amounts (caffeine, taurine, sodium), where disclosed

We say which kind of evidence each claim rests on. “Caused tumors in mice at high doses” and “linked to hyperactivity in a randomized trial of children” are very different findings, and the post treats them differently.

3. We rank the concerns

Each post ends with a verdict and a ranked list of what actually matters in that product. The ranking is by strength of evidence and size of effect, not by how alarming the ingredient sounds. That’s why sugar usually comes first and the unpronounceable emulsifier usually comes last.

4. We link our sources

Posts cite the specific FDA notices, EFSA opinions, and studies they rely on. If a claim isn’t sourced, treat it as our reading of the evidence rather than a settled fact.

5. We date and update

Every post carries a “last reviewed” date at the top. We re-check posts when a product reformulates, a regulator acts, or a significant study is published, and we note what changed. Older posts that no longer meet this standard are rewritten or removed.

What we don’t do

• We don’t take payment or free product from the brands we cover.
• We don’t give medical advice. The posts are informational; your doctor or a registered dietitian knows your situation.
• We don’t use AI-generated images of products. Label cards on the site are our own graphics built from the real ingredient list; product photos are ours.
