You have probably heard that carrots were invented to help pilots see at night, that MSG causes headaches, or that searing meat “locks in” the juices. These food and drink facts get repeated at dinner tables until they feel settled. Then you look for the primary source and find either a wartime propaganda office, a single flawed study, or nobody at all. Below are fifteen claims worth testing — some turn out true, some turn out exaggerated, and a few are simply unknown. Each entry points you to a real, checkable place to start.

Why food and drink facts deserve a second look
Food folklore spreads faster than almost any other kind of claim, because it arrives attached to something we do every day. The American Council on Science and Health and similar bodies have documented how a single small study can become a decade of headlines. Meanwhile, most people never read past the summary. The tools below are the ones I use when a claim sounds too tidy — the places where you can find the original study, the correction, or the honest “we don’t know yet.” None of them require a science degree, and all of them are free.
15 food and drink facts worth checking
1. Snopes : The fact-check starting point for viral food claims
What it is: A long-running fact-checking site with a deep archive of food and drink rumors, from “microwaves destroy nutrients” to “bananas are radioactive.”
Category: Fact-checking
Why it stands out: Each entry lists its sources and ratings, so you can see whether a claim is true, false, or a mixture — the last category is the most common and the most useful.
Best for: Anyone who just received a forwarded message about a food scare.
2. World Health Organization : Official positions on additives, sugar, and processed meat
What it is: The UN health agency’s public pages and fact sheets on nutrition and food safety.
Category: Public health
Why it stands out: When people say “the WHO says bacon causes cancer,” you can read the actual 2015 IARC classification — which placed processed meat in Group 1 based on strength of evidence, not level of risk.
Best for: Untangling headlines that oversimplify a hazard classification.
3. USDA FoodData Central : Real numbers behind nutrition claims
What it is: The US government’s searchable database of nutrient values for thousands of foods.
Category: Nutrition data
Why it stands out: It distinguishes between lab-analyzed and label-derived values, which matters when a recipe blog claims a suspiciously round calorie count.
Best for: Checking whether a food really contains as much protein or fiber as claimed.
4. Harvard T.H. Chan Nutrition Source : Plain-language summaries of nutrition research
What it is: A university-run site that translates nutrition studies for general readers.
Category: Nutrition science
Why it stands out: It is careful about uncertainty — pages on eggs, coffee, and salt openly note where evidence conflicts rather than picking a side.
Best for: Readers who want nuance without a journal subscription.
5. Retraction Watch : Find out when a famous food study was withdrawn
What it is: A blog and database tracking retracted scientific papers.
Category: Research integrity
Why it stands out: Some widely cited diet studies have been retracted years after the headlines; searching a study’s authors here is a fast sanity check.
Best for: Anyone citing an old study they found on page one of search results.
6. PubPeer : Post-publication comments on specific papers
What it is: A platform where researchers leave comments on published studies.
Category: Research integrity
Why it stands out: Comments often flag image duplication or statistical oddities that never made the news. It is not a verdict, just a conversation — treat it as a prompt to dig further.
Best for: Checking a specific paper before you repeat its finding.
7. Google Scholar : Trace a claim back to the original study
What it is: A search engine for academic literature.
Category: Research search
Why it stands out: The “cited by” link shows you who has challenged a paper since publication — often the fastest route to a rebuttal.
Best for: Finding the source behind a statistic quoted in an article.
8. Our World in Data : Charts that show whether a food trend is real
What it is: An open research publication with long-run data on food supply, diets, and agriculture.
Category: Data visualization
Why it stands out: Every chart links to its underlying dataset, so you can check whether “meat consumption is falling” holds up across countries or only in one.
Best for: Big-picture claims about what the world eats.
9. FDA Food Safety : Official guidance on storage and handling
What it is: US regulator pages on foodborne illness, recalls, and safe storage.
Category: Food safety
Why it stands out: It settles practical disputes — like whether leftovers are safe after four days — with stated temperature and time thresholds rather than folklore.
Best for: Kitchen arguments about the fridge.
10. EU RASFF : The alert system behind European food recalls
What it is: The EU’s rapid alert system for food and feed, with a public search window.
Category: Food safety
Why it stands out: It shows real recall notifications by product and country — useful for checking whether a specific imported product has been flagged.
Best for: Readers outside the US who want non-American regulatory data.
11. Open Food Facts : Crowdsourced ingredient and nutrition labels
What it is: A volunteer-built open database of packaged food products worldwide.
Category: Open data
Why it stands out: You can scan a barcode and see the label as entered by contributors — handy for comparing sugar content across similar products. Coverage varies by country, so treat gaps as gaps, not absences.
Best for: Comparing products without standing in the aisle.
12. Serious Eats Food Science : Tested explanations of cooking claims
What it is: A food publication known for kitchen testing and food-science explainers.
Category: Culinary science
Why it stands out: Claims like “salting pasta water makes it boil faster” get tested rather than repeated, and the results are explained in plain terms.
Best for: Home cooks who want to know why a technique works.
13. The Nutrition Source Glossary : Decode the vocabulary of food claims
What it is: A reference section defining terms like “whole grain,” “added sugar,” and “ultra-processed.”
Category: Reference
Why it stands out: Many food arguments are really definition arguments; once “processed” is defined, half the dispute dissolves.
Best for: Settling debates that turn on wording.
14. Internet Archive : See what a food page said before it changed
What it is: A nonprofit digital library with a Wayback Machine for old web pages.
Category: Archiving
Why it stands out: Brand and agency pages quietly revise health claims; archived snapshots let you compare versions and see what was removed.
Best for: Tracking how a claim evolved over time.
15. Wikipedia’s Citation Needed : A reminder to check the footnote, not the sentence
What it is: Wikipedia’s own documentation on why unsourced statements get flagged.
Category: Media literacy
Why it stands out: It is a short, honest read on how claims enter an encyclopedia — and a good habit-builder: click the footnote before you trust the line.
Best for: Building a checking reflex in under five minutes.
Bonus mentions
The Food Timeline : Dated food history references
A librarian-built chronology of when dishes and ingredients appeared, with citations. Contested dates are noted rather than smoothed over.
EFSA : Europe’s food safety science authority
Useful when a claim cites “European regulators” — the actual opinions are published and searchable.
NHS Eat Well : Practical, non-commercial nutrition guidance
Plain pages with no product ties, good for baseline advice on salt, sugar, and portion size.
FDA Enforcement Reports : Search actual recall records
Check whether a specific product was really recalled, and when.
Where to start checking
Most food and drink facts are not lies — they are half-truths that lost their qualifiers somewhere between a journal abstract and a group chat. The habit that fixes this is small: find the primary source, read the date, and notice whether it says “associated with” or “causes.” When a claim is contested, say so. When it is unknown, say that too. That is more honest than most headlines manage.
Check it twice, then share it.

Marta writes about the everyday facts people repeat without checking, from kitchen science to common sayings. Her angle is simple: find the original source, show what it actually says, and explain where the popular version drifted. She favors short pieces that end with a clear takeaway you can use the next time the topic comes up.
