Bad health advice is not new. What is new is how fast it moves, how polished it looks, and where it comes from. In 2025 and 2026, some of the most widely shared health claims in America came from social media feeds, AI chatbots, supplement ads, and, more and more, from people at the very top of the federal health system.
This article lays out what is happening, what it costs, what the evidence actually says, and how to find a doctor who follows it. It is also the reason DoctorDirectory.ai exists.
What medical misinformation is, and why it spreads
Medical misinformation is health information that is false, misleading, or missing the context you need to make a safe choice. When someone spreads it on purpose, to sell something or win an argument, it is called disinformation.
In 2021 the U.S. Surgeon General called health misinformation an "urgent threat" to public health. The World Health Organization uses the word "infodemic" for the flood of true and false information that hits during a health crisis.
It spreads because it is built to. A scary claim gets more clicks than a careful one. A product with a "secret the doctors won't tell you" sells better than a statin. And more people now get health advice from places with no editor at all. In a June 2026 KFF poll, 31% of U.S. adults said they use social media for health information at least once a month, and 29% said they use AI chatbots, up from 17% in 2024.
What misinformation costs
Misinformation is not just annoying. It costs money and lives.
- Money. Researchers at the Johns Hopkins Center for Health Security estimated that COVID vaccine misinformation cost the U.S. between $50 million and $300 million a day in 2021, through illness, hospital care, and lost work.
- Measles. As of October 29, 2026, the CDC had counted 4,852 confirmed measles cases in the U.S. this year, more than double all of 2025 (2,289) and the highest count in more than three decades. Three people have died. Measles was declared eliminated in the U.S. in 2000. Two doses of the MMR vaccine are about 97% effective.
- Trust. When people stop trusting good advice, they also stop acting on it. That is how preventable diseases come back.
When the misinformation comes from the top
For most of the last 50 years, federal health agencies were where doctors and patients went for the evidence. Since 2025, that has become harder. Here is what has happened, in the officials' own words where we have them. We link to the reporting so you can read it yourself.
Vaccines
- The vaccine advisory panel was replaced. In June 2025, Health and Human Services Secretary Robert F. Kennedy Jr. removed all 17 members of the CDC's vaccine advisory committee (ACIP), saying "a clean sweep is necessary to reestablish public confidence in vaccine science." Several of the new members were known vaccine critics.
- COVID shots. In May 2025, Kennedy announced in a video that the CDC would no longer recommend COVID vaccines for healthy children and pregnant women, without a vote by the advisory panel.
- Measles. During the 2025 Texas outbreak, Kennedy promoted vitamin A and cod liver oil. He also said MMR protection "wanes very quickly" and that the vaccine contains "aborted fetus debris." Experts told Reuters neither claim is true. To be fair, he has also called the MMR vaccine crucial. Mixed messages are part of the problem: people hear the doubt.
- Autism. In November 2025, the CDC's vaccine safety page was changed to say that "'Vaccines do not cause autism' is not an evidence-based claim." No new research was cited. Large studies, including more than a million children, have found no link between vaccines and autism.
- The childhood schedule. In December 2025, the new panel voted to end the universal hepatitis B shot at birth for babies of mothers who test negative. In January 2026, the CDC cut the list of diseases on the routine childhood schedule from 17 to 11, without a panel vote. On March 16, 2026, a federal judge put those changes on hold in a lawsuit brought by the American Academy of Pediatrics and others.
- Research. In August 2025, HHS canceled 22 mRNA vaccine projects worth about $500 million. That same month the White House fired the CDC director less than a month after she took office, following disagreements over vaccine policy.
Food and saturated fat
The new Dietary Guidelines for Americans, 2025 to 2030, came out on January 7, 2026, under the slogan "eat real food." Some of it is solid: eat more vegetables, fruit, and whole foods, and cut back on highly processed food and added sugar.
The trouble is the message about fat. The official text still says saturated fat "should not exceed 10% of total daily calories." That limit did not change. But the same guidelines name "butter or beef tallow" as cooking options, encourage full-fat dairy, and put red meat front and center. Kennedy announced, "We are ending the war on saturated fats." Months earlier he had praised a fast-food chain's switch to beef tallow fries. In January 2026, a new law brought whole milk back to school lunches.
Here is why heart doctors worry. Saturated fat raises LDL cholesterol, and LDL cholesterol causes heart disease, the leading cause of death in America. Harvard nutrition researchers point out that one tablespoon of butter has about 7 grams of saturated fat, about a third of the daily limit for many adults. The American Heart Association praised parts of the guidelines but warned that the advice on red meat and salt "could inadvertently lead consumers to exceed recommended limits for sodium and saturated fats." The AHA still recommends plant oils like olive oil over animal fats.
You will see claims online that the government now says to eat all the bacon, butter, and lard you want. That is not what the guidelines say. But when officials cheer for butter and tallow while the fine print keeps a limit, most people remember the cheer.
Peptides
Peptides are short chains of amino acids. Some are proven, approved medicines: insulin and the GLP-1 drugs used for diabetes and weight loss are peptides. But a large online market sells unapproved "research peptides," like BPC-157, for injuries, aging, and muscle, often with no prescription and no proof.
- In October 2024, before taking office, Kennedy posted that the FDA's "aggressive suppression" of "peptides, stem cells, raw milk," and other products would end.
- In March 2026, he told a podcast audience, "I'm a big fan of peptides," said he had used them himself, and said the FDA would lift limits on about 14 of them.
- On July 23, 2026, an FDA advisory committee voted 8 to 6 to let pharmacies compound BPC-157, against the advice of FDA's own staff. The vote does not make it approved or proven. It is not a final rule.
The human evidence for BPC-157 is close to nothing: a few small studies, and no good trials showing it heals injuries in people. "Popular" and "allowed to be compounded" are not the same as safe and effective. A product you inject should have to prove itself first.
Tylenol, fluoride, and raw milk
- Tylenol and autism. In September 2025, the President linked acetaminophen use in pregnancy to autism. The FDA's own letter to doctors called the link unproven, and the American College of Obstetricians and Gynecologists called the claim "irresponsible" and "not backed by the full body of scientific evidence." Untreated fever in pregnancy carries its own risks.
- Fluoride. Kennedy has called fluoride "industrial waste." Utah and Florida banned it in public water in 2025, and the FDA moved to pull fluoride drops and tablets prescribed for children. Community water fluoridation has helped prevent tooth decay for 80 years.
- Raw milk. Kennedy drinks it and has promoted it. The FDA's own guidance still says "raw milk puts all consumers at risk" of infections like Salmonella, E. coli, and Listeria.
Dr. Oz
Dr. Mehmet Oz now runs the Centers for Medicare and Medicaid Services. On TV, his record was uneven. In 2014, senators scolded him for calling green coffee extract a "miracle" weight loss product; he admitted his language was "flowery." A BMJ study that year found the evidence supported only 46% of the recommendations on his show. In 2020 he promoted hydroxychloroquine for COVID. To his credit, in February 2026 he urged Americans during the measles surge: "Take the vaccine, please." That is the right message, and we wish it were the only one coming from Washington.
The wellness industry: big money, thin proof
The Global Wellness Institute puts the global wellness economy at $6.8 trillion in 2024, close to $7 trillion, and expects it to reach $9.8 trillion by 2029. Much of that is fine: gyms, healthy food, travel, and skin care. But inside it is a huge market for products that promise to cure, detox, reverse aging, or fix your hormones, with little or no proof.
That market depends on a gap in the law. The FDA says plainly: "FDA does not have the authority to approve dietary supplements before they are marketed." A company can start selling a supplement without showing it works or is safe. The Federal Trade Commission steps in after the fact, like when it made one company refund customers over unproven weight loss and health claims. By then, the money is spent.
Our founder, Dr. Mohammed Alo, a cardiologist, breaks this market down in The Ultimate Guide to Wellness Scams: What the $7 Trillion Industry Is Hiding. Supplements alone were a $192 billion market in 2024, a category he flags for high scam exposure. And the FTC has made wellness companies pay: Herbalife paid $200 million to consumers in 2016 over misleading claims about what its sellers could earn, and the makers of Lumosity paid $2 million to settle FTC charges that their brain-training ads were deceptive. He covers it on video too: the wellness scam industry. The pattern is always similar. A real fear, a simple villain, a product to buy, and a story about doctors hiding the truth.
Who people trust now
Here is the good news. When trust in agencies drops, most people still trust their own doctor.
- In KFF polling from 2026, 86% of adults said they trust their own doctor for reliable health information, compared with about half who trust the CDC. (KFF)
- In a spring 2026 poll by the Harvard T.H. Chan School and the de Beaumont Foundation, only 38% agreed that federal health agencies' recommendations follow the best available science.
- Having a trusted doctor protects people from myths. In a KFF poll published June 2026, 46% of adults without a trusted doctor thought a common COVID vaccine myth was probably true, compared with 24% of those with one.
- Most people still believe in proven vaccines: in KFF's fall 2026 poll, 82% said the benefits of the MMR vaccine outweigh the risks. But 48% of parents wrongly think spacing out shots is healthier.
That is why the doctor you choose matters so much. Your doctor may be the one trusted voice left between you and the noise.
What following the evidence actually does
Guidelines are not opinions. They are summaries of what large, careful studies have found. When doctors follow them, people live longer.
- Cholesterol. In a review of 26 trials with about 170,000 people, each drop of 1 mmol/L (about 39 mg/dL) in LDL cholesterol on a statin cut major heart attacks and strokes by 22% and deaths from any cause by 10% (Lancet, 2010).
- Blood pressure. In 123 trials with more than 600,000 people, every 10-point drop in the top blood pressure number cut major heart events by about 20% and deaths by 13% (Lancet, 2016).
- Vaccines. Worldwide, vaccines have saved an estimated 154 million lives in 50 years, most of them babies. In the U.S., the CDC estimates routine childhood shots given to children born from 1994 to 2023 will prevent about 1.1 million deaths.
Evidence-based doctors also say "we don't know yet" when the evidence is not in, and they change their advice when better studies come out. That is not weakness. That is how science is supposed to work.
How to spot health misinformation
Be careful when a health claim:
- Promises a cure, a "reset," or results that sound too good to be true.
- Says doctors, drug companies, or "Big Pharma" are hiding the truth.
- Comes with a product, a discount code, or a supplement to buy.
- Uses one person's story instead of studies with many people.
- Tells you to stop a medicine your doctor prescribed.
- Is labeled "natural," as if natural means safe. Lead and arsenic are natural too.
- Cites "a study" without a link, or a study in mice or a test tube.
When in doubt, ask a doctor who follows the evidence. Our guide on how to know if your doctor is a quack covers the warning signs in a clinician.
Why DoctorDirectory.ai exists
We built DoctorDirectory.ai because patients deserve a simple way to find doctors who practice evidence-based, guideline-based medicine, at a time when bad advice is everywhere.
- We vet every listed doctor. We check their license, board certification, every state medical board, court and FTC records, and their own website and public posts. See how we vet.
- Some people can never be listed. Clinicians who spread anti-vaccine claims, sell unproven peptides or treatments, have lost their license, or have faced FTC action for health claims are not eligible. A physician makes the final call, and we check again after listing.
- No reviews and no star ratings. Star ratings measure wait times and bedside manner, not whether a doctor follows the science.
- Not pay to play. Vetting is free and cannot be bought. Paid features never change who is listed or how we vet.
Doctors who stick to the evidence are doing hard, unglamorous work right now. They deserve to be found. You deserve to find them. Search for a vetted doctor near you.
If you are a physician who practices this way, check if you are listed and claim your free profile.
Common questions
Is BPC-157 safe?
No one knows, which is the problem. BPC-157 has almost no testing in people. It is not FDA approved. An FDA advisory committee voted in July 2026 to let pharmacies compound it, against the advice of FDA staff, but that vote did not prove it safe or effective. Talk to a doctor before injecting anything that has not been tested in people.
Did the new dietary guidelines remove the limit on saturated fat?
No. The 2025 to 2030 guidelines still say saturated fat should be no more than 10% of daily calories. They also list butter and beef tallow as cooking options and encourage full-fat dairy, which makes that limit hard to meet. Heart experts still recommend plant oils like olive oil over animal fats.
Are childhood vaccines still recommended?
Yes. A federal judge put the 2026 cuts to the childhood schedule on hold in March 2026, and the American Academy of Pediatrics continues to recommend the full schedule. Ask your child's doctor about anything you are unsure of.
How can I tell if health advice online is wrong?
Watch for promises of a cure, claims that doctors are hiding the truth, a product to buy, and stories in place of studies. Check whether major medical groups agree, and ask a doctor who follows the evidence.
How does DoctorDirectory.ai choose which doctors to list?
We check each doctor's license, board certification, state medical board records, court and FTC records, and their own public posts and website. A physician makes the final call. Vetting is free, and no one can pay to be listed or to skip a check.
