Do sardines actually make your skin glow?

The biology is plausible but the direct evidence is limited. Sardines are rich in omega-3 fatty acids, vitamin B12, selenium, and vitamin D — nutrients with established skin benefits including supporting the skin barrier, reducing inflammation, and supporting collagen production. However, no direct clinical trials have specifically measured skin improvement from eating sardines. The skin benefits come from the nutrients, not sardines specifically — any omega-3-rich food or quality supplement achieves similar results.

Does drinking chlorophyll water clear acne?

Fiction. There is no scientific research backing the claim that drinking chlorophyll water clears skin. The limited positive evidence that exists is for topical chlorophyllin — a chemically modified form applied directly to skin — not for oral consumption. Dermatologists suggest that any improvement people notice from drinking chlorophyll water is more likely from drinking more water overall, since proper hydration genuinely helps skin health.

Is beef tallow actually nature's Botox?

No. There is no verifiable scientific evidence that beef tallow functions as a Botox alternative. Botox works by blocking nerve signals to paralyze specific facial muscles — nothing applied topically can achieve this. Beef tallow has legitimate moisturizing properties for very dry skin, but it cannot fade dark spots, treat acne, or replace retinol. People with oily or acne-prone skin may find it clogs pores and worsens breakouts.

Is raw milk more nutritious than pasteurized milk?

Fiction — and a dangerous one. Both raw and pasteurized milk contain identical nutritional profiles. Pasteurization kills harmful bacteria without meaningfully altering nutritional content. From 1998 to 2018, the CDC documented 202 outbreaks linked to raw milk consumption causing 2,645 illnesses and 228 hospitalizations. A 2017 study found unpasteurized dairy causes 840 times more illnesses than pasteurized products. Raw milk can carry Salmonella, E. coli, Listeria, and Campylobacter — posing particular danger to pregnant women, children, and immunocompromised individuals.

Is mouth taping safe for better sleep?

Mostly fiction with a serious safety warning. A 2025 systematic review of 10 studies published in PLOS One found minimal evidence that mouth taping improves sleep apnea or sleep quality. More critically, mouth taping poses a genuine asphyxiation risk for anyone with nasal obstruction — including deviated septum, chronic congestion, or undiagnosed sleep apnea. People with moderate or severe sleep apnea can make their condition significantly worse. Researchers explicitly state the trend is 'guided by poor evidence and can lead to risk of serious health harm.'

Does fibermaxxing actually work for blood sugar control?

Largely fact. Eating fiber before carbohydrate-heavy meals creates a viscous gel in the digestive tract that slows glucose absorption and blunts blood sugar spikes. A 2025 Nature Medicine study confirmed fiber preloading measurably alters postprandial glucose responses. This is one of the few viral wellness trends with solid science behind it. Caveat: dramatically increasing fiber intake too quickly causes digestive distress — increase gradually and drink adequate water. 95% of people are not meeting recommended daily fiber intake, so almost any increase delivers benefits.

Does castor oil actually grow hair?

Mostly fiction for hair growth specifically. There are no high-quality clinical studies proving castor oil increases hair growth speed or density. Castor oil does have legitimate benefits as a moisturizer and scalp conditioner — it can reduce breakage, hydrate the scalp, and improve hair appearance. But it cannot reverse genetic hair loss, reactivate dormant follicles, or deliver the dramatic density changes shown in TikTok before-and-after videos. The FDA approves castor oil for one use: as a stimulant laxative. Liver detox and immune system claims are unsupported by evidence.

Does okra water help with weight loss?

Partial fact. Okra contains soluble fiber and mucilage that can slow digestion, promote fullness, and support blood sugar regulation — and a 2024 meta-analysis found okra consumption significantly reduced fasting blood glucose. However, okra water contains only trace amounts of these beneficial compounds compared to eating the whole vegetable. The weight loss claim is overstated — being low-calorie is not the same as being a fat-loss solution. Eating okra delivers more benefit than drinking the water it soaked in.

TikTok Health Hacks Fact or Fiction

Welcome to the first installment of what is going to be a recurring series on this blog, because the misinformation machine never sleeps and frankly neither do I.

Here's the premise: social media — specifically TikTok and Instagram — has become one of the most powerful health communication platforms in the world. Social media influencers with no medical training are pushing extreme diets, detox teas, DIY hormone resets, and viral wellness hacks to millions of followers with zero accountability. Some of what goes viral is genuinely useful. A lot of it is harmless but overhyped. And some of it is actually dangerous.

This post is not here to shame anyone for trying something they saw online. We have all been there — it is 11pm, an algorithm has decided we need to know about okra water, and suddenly we are very interested. The goal here is to give you the actual science so you can make an informed decision rather than an impulsive one.

No judgment. Just research. Let's go.

TikTok health hacks fact or fiction

🐟Eating Sardines Will Make Your Skin Glow

✅ FACT — With Important Nuance

This one blew up after Victoria's Secret model Anok Yai revealed backstage at the 2025 fashion show that sardines are her secret to glowing skin. And unlike most celebrity wellness claims, this one actually has biological plausibility behind it.

A 100-gram serving of sardines contains more than 370% of the recommended daily value of vitamin B12, 96% of the recommended daily value of selenium, 24% of vitamin D, and 982 milligrams of omega-3 fatty acids per serving — more than some omega-3 supplements provide. Hypebae

Here's why that matters for skin specifically. Omega-3 fatty acids help your body produce more ceramides — the fats that hold your skin barrier together — and they dial down inflammation. Vitamin D supports skin cell growth and repair. Protein is essential for collagen production. These are not minor players. These are the exact nutrients that dermatologists recommend for skin health. Northeastern University

A 2025 systematic review found that topical omega-3 use showed positive effects on improving skin conditions, reducing irritation and inflammation, enhancing wound healing, and improving hydration across almost all studies reviewed. And while that research is on topical application, the dietary connection is clear: participants who applied EPA and DHA-rich sardine oil to their skin after UVB exposure experienced around 25% less skin redness compared to a control group. Oregon State University Linus Pauling Institute

The honest caveat: there are no direct clinical trials specifically on eating sardines and observing skin improvement. The dermatologists are divided — some call it conclusive, others call it promising-but-unproven. The ingredients in sardines have meaningful evidence for skin benefits. Whether sardines specifically are the delivery mechanism, or whether any omega-3-rich food achieves the same result, is less clear.

The verdict: The biology checks out. The specific sardine claim is extrapolated from solid nutrient science rather than direct sardine-skin trials. Eat them if you like them — they are one of the most nutrient-dense, affordable foods available. Don't eat them if you hate them and expect a miracle. Your skin will not know the difference between a sardine and a high-quality omega-3 supplement.

Pro tip: Canned sardines in olive oil are cheap, shelf-stable, and pack more omega-3s than most supplements. A $2 can is genuinely one of the most nutritious things you can put in your body.

🌿Drinking Chlorophyll Water Will Clear Your Acne

❌ FICTION

This one has been circulating for years and keeps coming back because the before-and-after photos are compelling and the green color looks dramatic and medicinal. Neither of those things is evidence.

There is no scientific research backing the claim that drinking chlorophyll water clears your skin. The claims are primarily based on anecdotal testimonials.

Here's what the research actually says: the claims surrounding chlorophyll water for acne are loosely tied to lab studies showing antioxidant and anti-inflammatory properties, and to small trials of topical chlorophyllin for wound healing — not oral supplementation. Read that carefully. The limited positive evidence that exists is for a chemically modified version of chlorophyll (chlorophyllin) applied directly to skin — not for drinking it. Healthgrades

Preliminary studies suggest that liquid chlorophyll can be detoxifying and anti-inflammatory — however, there is no real evidence to support this applied to oral consumption. It is more likely that people seeing results from this trend are experiencing the benefits of drinking more water. Proper hydration helps with acne, keeps you fuller longer, and helps with fatigue. Healthgrades

In other words: the water is doing the work. Not the chlorophyll.

There is also a significant biological barrier here that nobody on TikTok mentions: chlorophyll is a large, complex molecule. When you consume it orally, your digestive system breaks it down. What reaches your bloodstream — if anything meaningful does — is not the same compound that has anti-inflammatory properties in a lab setting. The focus on being "natural" and tapping into hopes for clear, youthful skin pushes a narrative — but true health starts from the inside out through fundamentals like sleep, hydration, and nutrition. McGill Office for Science and Society

The verdict: Save your money. Drink more water — actual, plain water. If you want something that genuinely helps acne from the inside, the omega-3 research is far stronger than the chlorophyll data.

🥩 Beef Tallow Is "Nature's Botox" and Will Fade Acne and Dark Spots

❌ MOSTLY FICTION — PARTIAL FACT FOR DRY SKIN ONLY

This one is everywhere right now, and it has three distinct claims embedded in it that deserve to be addressed separately.

Claim 1: Beef tallow is "nature's Botox." There is no verifiable scientific evidence supporting the efficacy of beef tallow as a Botox alternative. The term "nature's Botox" is a misleading framing — topical application of natural ingredients cannot penetrate the skin deeply enough to relax or paralyze underlying facial muscles the way Botox injections do. Botox works by blocking nerve signals to specific muscles. Nothing you put on the surface of your skin achieves this. The "nature's Botox" claim is marketing language, not biology. National Geographic

Claim 2: It will fade acne and dark spots. Beef tallow is highly occlusive — meaning it forms a protective film on the skin that locks in moisture. For people with very dry or dehydrated skin, this can deliver noticeably softer skin within days. However, it cannot replace targeted skin treatments for concerns like wrinkles, dark spots, or breakouts. For acne-prone or oily skin, the occlusive nature of tallow can actually make things worse by clogging pores. A 2024 literature review concluded that beef tallow offers hydrating and moisturizing properties, but the short and long-term negative side effects are unknown, and the anti-acne and dark spot claims are not supported by evidence. National Geographic

Claim 3: It's a retinol replacement. No. Tallow and retinol do completely different things. Retinol is a vitamin A derivative that speeds up cell turnover — the process by which old skin cells are shed and replaced with new ones. This mechanism is what gives retinol its decades of clinical evidence for reducing wrinkles, fading dark spots, improving texture, and treating acne. Tallow moisturizes. It does not accelerate cell turnover. National Geographic

Board-certified dermatologist Dr. Rajani Katta puts it plainly: "This is a trend where the popularity has gotten ahead of the science." Dermatology Times

The verdict: If you have very dry skin and want a natural moisturizer, tallow may help — but so will dozens of better-researched alternatives with known safety profiles. For acne, dark spots, or anti-aging: it will not do what the TikTok videos claim. And please, for the love of everything, do not swap your retinol for beef fat.

🥛 Raw Milk Is More Nutritious Than Pasteurized Milk

❌❌❌ DANGEROUS FICTION — And We Need To Talk About This One

This is the entry on this list that I feel most strongly about, because it is not just misinformation — it is dangerous misinformation that has been amplified by wellness influencers across the political spectrum and is currently contributing to real public health harm.

Let's start with the nutrition claim, because it is the simplest to dispatch: both raw and pasteurized milk contain the same amounts of nutrients. Pasteurization effectively kills raw milk pathogens without any significant impact on milk nutritional quality. The FDA has published a fact sheet that debunks each of the misconceptions associated with raw milk. FDA

Same calcium. Same vitamin D. Same protein. Same everything. The nutritional argument for raw milk is not supported by evidence.

Now the safety issue: from 1998 through 2018, the Centers for Disease Control and Prevention documented 202 outbreaks linked to raw milk consumption, resulting in 2,645 people becoming ill and 228 people hospitalized. A 2017 study found that unpasteurized dairy products cause 840 times more illnesses and 45 times more hospitalizations than pasteurized products. American Academy of Pediatrics

840 times more illnesses. Let that number sit for a moment.

Raw milk can carry dangerous germs including Salmonella, E. coli, Listeria, and Campylobacter. These germs can seriously injure anyone who drinks raw milk — but they are especially dangerous to people with weakened immune systems, children, older adults, and pregnant women. Pregnant women run a serious risk of becoming ill from Listeria found in raw milk, which can cause miscarriage, illness, or death of the newborn baby. FDA

Pasteurization — first developed by Louis Pasteur in 1864 — kills harmful organisms responsible for listeriosis, typhoid fever, tuberculosis, diphtheria, Q fever, and brucellosis. These are not historical diseases. These are diseases that still exist and that raw milk can transmit. FDA

The claim that raw milk contains beneficial probiotic bacteria is also false. The bacteria present in raw milk are typically not probiotic and can include harmful pathogens. American Academy of Pediatrics

The verdict: Do not drink raw milk. Do not give it to your children. The nutritional argument is fiction and the safety risk is real, documented, and significant. This is one of the few entries on this list where I am not hedging.

🫙 Okra Water Can Suppress Appetite and Support Weight Loss

🟡 PARTIAL FACT

Okra water is made by soaking okra pods in water overnight and drinking the resulting slightly viscous liquid. The claims range from appetite suppression to blood sugar regulation to weight loss.

Here's the nuanced truth.

When okra is soaked in water, mucilage — the gel-like substance that makes okra slimy — leaches out into the water. This mucilage contains soluble fiber, which creates a viscous gel in the digestive tract that can slow gastric emptying, promote feelings of fullness, and help blunt blood sugar spikes. These are real mechanisms with real research behind them.

A 2024 meta-analysis including eight studies and 521 participants found that okra consumption significantly decreased fasting blood glucose and HbA1c compared to placebo — meaningful findings for blood sugar management. nih

However, there is an important distinction the viral content glosses over: drinking okra-infused water is not the same as eating the vegetable. Whole okra provides substantially more fiber and nutrients than okra water, which contains only trace amounts of the mucilage that actually delivers the benefit. Eating vegetables beats drinking them from a nutritional standpoint. nih

On the weight loss claim specifically: okra water should not be considered a magic solution for fat loss. Being low-calorie is not the same as being filling or nutritionally complete. If you are drinking it instead of higher-calorie options, that swap may support weight loss efforts — but that is hydration doing the work, not okra magic. noom

The verdict: Partially true — okra has legitimate fiber and blood sugar benefits, and okra water contains trace amounts of those properties. But the weight loss claim is overstated, and eating the actual vegetable is dramatically more effective than drinking the water it soaked in. If you like okra, eat okra. If you don't, there are better fiber sources.

👄 Mouth Taping Will Improve Your Sleep and Stop Snoring

❌ MOSTLY FICTION — With A Danger Warning

This one has been endorsed by celebrities including Gwyneth Paltrow and Ashley Graham, which is exactly the kind of credential that should make you more skeptical, not less.

The premise: tape your mouth shut while sleeping to force nasal breathing, which supposedly improves sleep quality, reduces snoring, fixes sleep apnea, and even changes jaw structure.

A 2025 systematic review published in PLOS One — evaluating 10 previously published studies — found minimal evidence that mouth taping improves sleep apnea, with only slight improvement seen in a subset of patients with mild apnea. The review concluded that existing evidence does not support nighttime mouth taping as a treatment for sleep-disordered breathing. PLOS

But here's the part that matters most: mouth taping can pose a serious risk of asphyxiation for individuals with any kind of nasal obstruction. If your nose cannot handle all your breathing — due to a deviated septum, chronic congestion, swollen turbinates, or enlarged tonsils — taping your mouth shut creates a genuine suffocation risk. People with moderate or severe obstructive sleep apnea face particular danger, as mouth taping can make existing sleep-disordered breathing worse by restricting airflow and putting additional stress on the respiratory system. PLOS

The researchers were unambiguous: "Many people are not appropriate for mouth taping, and in some cases it can lead to risk of serious health harm." PLOS

The problem is that many people with undiagnosed sleep apnea — who would be at highest risk from mouth taping — do not know they have it. You could be one of them.

The verdict: The evidence for benefit is weak. The evidence for potential harm is real and peer-reviewed. If you are concerned about mouth breathing or snoring, see a sleep specialist or an ENT. Do not seal your airway shut based on a TikTok trend endorsed by someone who sells overpriced wellness products.

🫚 Castor Oil Will Grow Your Hair, Clear Your Skin, and Detox Your Liver

🟡 PARTIAL FACT — With Significant Caveats

Castor oil is genuinely one of the most overpromised substances on the internet right now. The claims range from reasonable to truly unhinged — including people putting it in their eyes, which ophthalmologists have specifically warned against.

Let's separate what the evidence actually supports:

What castor oil legitimately does: Castor oil is rich in ricinoleic acid, an omega-9 fatty acid with natural emollient properties that helps hydrate and smooth the skin. It can moisturize the scalp, reduce breakage, seal in hydration, and add shine to hair. As a moisturizer and scalp conditioner, it has plausible biology behind it and a long history of use across multiple cultures. iRestore

What castor oil does not do: There is no clinical evidence proving castor oil speeds up hair growth, reverses genetic hair loss, or significantly increases hair density. No high-quality clinical studies prove that castor oil increases hair growth speed. Most claims are anecdotal and based on personal experiences rather than scientific trials. The before-and-after TikTok videos showing dramatic hair regrowth are not evidence — they are content. iRestore

The liver detox claim is even more problematic. The FDA approves castor oil for exactly one use: as a stimulant laxative. It is probably best known as a natural treatment for occasional constipation. Claims about liver detoxification, immune system boosting, and systemic health benefits through castor oil packs have little to no scientific backing. Today Show

The verdict: As a moisturizer and scalp conditioner for dry hair and skin — sure, it has biological basis and a long track record. As a hair growth miracle, liver detox, or cure for anything beyond constipation — the evidence is not there. Use it for what it actually does. Don't put it in your eyes.

🌾 Fibermaxxing — Eating Fiber Before Carbs to Blunt Blood Sugar Spikes

✅ LARGELY FACT — And One of the Better Trends on This List

This one went viral partly because actress Kristen Bell's co-star revealed at the 2025 Emmys that Bell strategically eats fiber before carb-heavy meals to stabilize blood sugar. Unlike most celebrity wellness claims, this one is grounded in actual science.

A growing body of evidence suggests that changing the order in which you eat — starting with fiber and protein before carbohydrates — can help stabilize blood sugar levels. The mechanism is straightforward: soluble fiber forms a viscous gel in the digestive tract that slows the absorption of glucose from carbohydrates eaten afterward, reducing the spike. Nature Medicine

Research shows that fiber can support immune function, inflammation control, blood glucose and insulin regulation, and even mood, cognition, and stress response. A 2025 Nature Medicine study examining preloading a rice meal with fiber, protein, or fat found that fiber preloading measurably altered postprandial glucose responses — with considerable individual variation. Nature Medicine

The nuance worth knowing: too much fiber too quickly can be very problematic from a gastrointestinal perspective. If you currently eat very little fiber and dramatically increase your intake overnight, you will likely experience bloating, cramping, and other digestive distress. The recommendation is to increase fiber gradually and drink adequate water alongside it. Nature Medicine

Also worth noting: 95% of people are not getting enough fiber in their diets as it stands. The baseline is very low. Almost any increase in fiber intake is going to have positive effects — whether you eat it strategically before carbs or just eat more of it generally. NutraIngredients

The verdict: This is one of the few viral wellness trends where the underlying science is solid, the mechanism is well-understood, and the behavior change is both safe and achievable. Start your meal with vegetables, legumes, or a fiber supplement before the pasta. Your blood sugar will thank you — and so will everything else, given how central fiber is to gut health, cardiovascular health, and metabolic function.

The Through-Line

Here is what every entry on this list has in common: the claim preceded the evidence. Something looked good on camera, got shared by someone with a large following, and spread faster than any fact-check could keep up with. That is not unique to health content — it is just how social media works. The difference is that health misinformation has real consequences.

The rule I use before trying anything I see online: who is making this claim, what are their credentials, and where is the research? If the answer is "an influencer, no credentials, and a before-and-after photo" — that is not enough. If the answer is "a board-certified dermatologist citing a peer-reviewed study" — now we're talking.
