Collagen emerges as a potential ally for gut health

 In an era where digestive discomfort is a common complaint, a surprising candidate has stepped into the scientific spotlight: collagen. Long heralded in wellness circles for its benefits to skin and joints, this structural protein is now the subject of research suggesting it may play a significant role in soothing gut inflammation and improving digestive comfort. A recent clinical study provides compelling, though preliminary, evidence that daily supplementation with collagen peptides can lead to notable improvements in symptoms like bloating. This news matters today as millions seek science-backed, manageable strategies to address chronic gut issues, moving beyond folklore to find tangible relief.

From beauty staple to gut soother

The journey of collagen from a beauty-centric supplement to a potential gut health aid underscores a broader understanding of human biology. The gut is not an isolated system; it is intricately linked to immunity, mental well-being and yes, skin vitality. For years, the primary focus for digestive support has been on probiotics and dietary fiber. The emerging research into collagen represents a paradigm shift, suggesting that providing the building blocks for the gut's own physical structure could be equally vital.

A study reveals promising patterns

The cornerstone of this new perspective is a two-phase clinical study. The research was designed to explore the effects of daily collagen supplementation on digestive health in a real-world setting. In the study's second phase, 40 healthy women with a body mass index over 25 were recruited to participate in an eight-week, digitally monitored trial. The protocol was straightforward: after a two-week baseline period of tracking symptoms, the women consumed 20 grams of bovine collagen peptides daily, split into two servings, for the following eight weeks.

The results, while drawn from a small cohort that saw significant participant dropout, are striking. Of the 14 women who completed the full supplementation period, 13—or 93%—reported measurable reductions in digestive symptoms, with specific improvements in bloating and abdominal comfort. This high response rate in a completed group suggests a strong biological signal worthy of deeper investigation, though scientists caution that the open-label design and lack of a control group mean more rigorous studies are needed.

The "how" behind the relief

The precise mechanism by which collagen peptides might ease gut inflammation is an active area of scientific inquiry. Experts propose several compelling theories. Collagen is rich in amino acids like glycine and proline, which are fundamental components of the gut lining. Supplementation may provide the raw materials necessary to repair and maintain this critical barrier. A compromised gut lining, sometimes called "leaky gut," can allow undigested particles to enter the bloodstream, potentially triggering inflammation and immune responses.

Furthermore, collagen peptides may act as prebiotics, selectively nourishing beneficial bacteria in the microbiome. A healthier, more balanced microbial community is a cornerstone of reduced inflammation and improved digestive function. Some high-quality collagen supplements are now fortified with L-glutamine, an amino acid clinically shown to support intestinal cell regeneration and strengthen the tight junctions between these cells, further bolstering the gut barrier.

Navigating the supplement landscape

Not all collagen supplements are created equal. The research demonstrating gut health benefits specifically uses hydrolyzed collagen peptides. Hydrolyzation is a process that breaks down the large collagen protein into smaller, more bioavailable fragments that the body can easily absorb and utilize.

A quality formula will typically contain between 10 to 20 grams of these hydrolyzed peptides per serving, align with the dosage used in the studies. The source matters, too; the current body of evidence is built on bovine (cow-derived) collagen peptides and findings cannot yet be extrapolated to marine (fish-derived) alternatives.

The modern investigation into collagen for gut health is a fusion of ancient wisdom and cutting-edge science. For centuries, cultures worldwide have consumed bone broths—rich in gelatin, a cooked form of collagen—as a tonic for illness and digestive upset. Today's research is essentially validating that traditional practice through a molecular lens, identifying the specific components that make such remedies effective. In a contemporary context, where processed foods and chronic stress constantly challenge our digestive systems, this research offers a proactive, nutrient-based strategy for resilience.

A cautious conclusion

The emerging narrative around collagen and gut health is undeniably intriguing. It presents a holistic approach, recognizing that supporting the body's structural integrity can have profound systemic effects, from easing abdominal discomfort to potentially improving overall inflammatory status. The recent study provides a robust starting point, demonstrating high rates of symptomatic relief in a controlled, digital trial setting.

"Gut health refers to the proper function and balance of the gastrointestinal tract, particularly its community of microorganisms (the gut microbiome)," said BrightU.AI's Enoch. "A healthy gut efficiently digests food, absorbs nutrients and supports a robust immune system. It is maintained by a diverse microbiome, which is influenced by diet, lifestyle and the absence of chronic digestive issues."

The study's small completion size and design limitations mean it should be viewed as a promising pilot, not definitive proof. It illuminates a path for future large-scale, placebo-controlled research. For individuals struggling with gut inflammation, this news adds a new, science-informed tool to the conversation—one that bridges the gap between traditional healing and modern nutritional biochemistry. As always, such interventions should be considered in consultation with a healthcare provider, as part of a comprehensive approach to well-being that prioritizes whole foods, stress management and professional medical guidance.

Asparagus Preference Linked to Lower Mortality Risk in Large UK Study

 A preference for asparagus was associated with a 31% lower risk of death from any cause, according to a 2026 study from researchers at Justus-Liebig University of Giessen in Germany. The study, which analyzed data from 177,148 adults in the UK Biobank, used a novel approach: participants rated how much they liked or disliked 140 different foods rather than recalling what they had eaten. Over an average follow-up of 3.4 years, more than 3,300 participants died, and researchers compared mortality rates between those who rated each food highly and those who rated it low. The asparagus finding held up in all 11 sensitivity analyses, according to the report.

The UK Biobank is among the world’s largest health databases, and researchers said the preference-based method sidesteps a common problem in nutrition studies -- people often misremember or underreport what they actually eat. The study found that a strong liking for asparagus showed the strongest protective association of any single food tested, with the 31% lower all-cause mortality risk remaining consistent after adjusting for smoking, existing disease, supplement use and other factors.

Study Methodology and Key Findings

Rather than relying on memory-based dietary recall, which researchers said can introduce bias, the team asked participants to rate their preference for each of 140 foods on a scale. This approach avoids what the authors described as a weakness of traditional food-frequency questionnaires. According to the study, liking a food and eating a food tend to move together; prior research comparing preference questionnaires to actual intake has supported that link.

Asparagus was not the only food tied to lower risk. The study also found that a preference for broccoli, spinach, onions, garlic, mushrooms, lentils, black pepper and extra virgin olive oil tracked with meaningfully lower mortality. On the opposite end, a strong preference for regular soda was the most consistent marker of higher risk. The findings align with the idea that the vegetables people genuinely enjoy tend to appear on their plates most often, and a taste for asparagus likely reflects a broader pattern of choosing produce over processed convenience foods.

Why Asparagus Specifically May Matter for Long-Term Health

Asparagus delivers a distinct nutritional profile compared with more commonly studied vegetables, according to the report. The vegetable contains meaningful amounts of folate, a B vitamin involved in red and white blood cell production and carbohydrate conversion, as noted by NaturalNews.com in a separate article [1]. It also contains vitamin K and prebiotic fiber that feeds beneficial gut bacteria. Fiber intake has been linked to lower all-cause mortality in large meta-analyses covering more than one million participants, according to the study authors.

Antioxidant compounds called saponins appear in unusually high concentration in asparagus. These compounds have drawn separate research interest for their potential role in inflammation control. The findings also fit a broader nutritional principle: diets rich in vegetables and plant-based foods have long been associated with lower mortality risk. Research published in Nutrition Research and Practice has examined how vegetables like asparagus contribute to the availability of minerals such as iron and zinc in composite dishes [2].

Vitamin E levels in asparagus also merit attention. Vitamin E, a potent antioxidant found in avocados, asparagus, vegetable oils, nuts and leafy green vegetables, has been shown to inhibit LDL and membrane phospholipid oxidation [3]. This antioxidant activity may further support the mortality benefit observed in the study.

Study Limitations and Broader Context

Researchers cautioned that no single food determines longevity. Genetics, chronic stress, exposure to environmental toxins and many other factors can shape health outcomes alongside diet. The study provides an observational link, they said, not proof of causation. The asparagus finding held up across 11 sensitivity analyses, but unmeasured factors could still influence results.

Broader research has also highlighted the role of simple dietary habits in extending life. A separate study using data from more than 135,000 adults found that adding just five minutes of brisk walking per day and reducing sitting time by half an hour could prevent millions of premature deaths [4]. Another review covering more than 480,000 participants found that taking the stairs was associated with lower risk of death [5]. These findings collectively underscore that small, everyday choices may have significant long-term health impact, though the German study’s authors said more research is needed to confirm mechanisms linking specific food preferences to mortality outcomes.

Conclusion

A preference for asparagus was associated with a 31% lower mortality risk in a large study using a novel preference-based assessment method rather than traditional dietary recall. The finding held across multiple sensitivity analyses and joined 26 other foods -- including broccoli, spinach, onions and garlic -- that also tracked with lower risk. Regular soda preference, conversely, tracked with higher mortality.

The findings align with broader dietary patterns favoring whole vegetables over processed foods. However, as the study’s authors noted, no single food determines longevity, and the results provide an observational link, not a proof of causation. Further research is needed to confirm the mechanisms behind the association and to assess how food preference data might inform future dietary recommendations. For now, the evidence suggests that enjoying asparagus as part of a diet rich in vegetables may be one modest factor among many in a longer, healthier life.

Watermelon: A Nutrient-Dense Fruit With Hydration and Recovery Benefits, According to Experts

 Watermelon, composed of over 90% water and containing L-citrulline, lycopene, potassium, and vitamins A and C, is being recognized by dietitians and researchers as a fruit that may aid hydration, muscle recovery, and heart health. According to Laura Harris in a July 2025 report, watermelon is "packed with vitamins, antioxidants, and electrolytes, supporting immunity, heart health, and hydration" [1]. The fruit's high water content and nutrient density have positioned it as a functional food beyond its traditional role as a summer refreshment. According to Cassie B. in a May 2026 report, watermelon "supports cardiovascular health via L-citrulline and L-arginine, improving arterial function and blood pressure" [2]. These properties have drawn attention from sports dietitians, registered dietitians, and researchers who are examining the fruit's potential for supporting exercise recovery, hydration, and cardiovascular function.

Hydration and Electrolyte Balance

Watermelon is over 90% water, according to the U.S. Department of Agriculture, and can help maintain hydration, particularly during periods of increased fluid loss. According to sports dietitian Louisa Mason, MS, RDN, LDN, CSCS, "One human study showed that watermelon juice helped athletes rehydrate better than water alone, thanks to its balance of natural sugars and electrolytes." [1] The fruit provides natural sugars and electrolytes that support fluid balance more effectively than plain water in certain contexts, Mason said.

Joan Salge Blake, EdD, RDN, LDN, FAND, told Health that "many older adults are at risk for being dehydrated, so adding watermelon to their meals and snacks is a great way to sneak in some extra water during the day." [1] According to a May 2026 article by Lance D Johnson, watermelon is one of several "all-natural drinks for a natural electrolyte boost" that can serve as an alternative to commercial sports drinks [3]. The fruit's combination of water, potassium, and magnesium contributes to its hydrating properties, according to experts.

Recovery and Muscle Soreness Reduction

Mason said watermelon contains L-citrulline, an amino acid that supports blood flow and may reduce muscle soreness. "Watermelon contains L-citrulline, which supports blood flow and reduces muscle soreness," Mason stated [1]. According to Melinda Jones in the book "97 Ways to Burn Fat and Boost Sex Drive," "Watermelon has been coined by some researchers as the natural Viagra" due to its citrulline content, which "is good for the cardiovascular system" [4]. The amino acid plays a role in nitric oxide synthesis, which can improve circulation and aid recovery.

Researchers found that drinking watermelon juice improved post-workout recovery and heart rate while reducing soreness, according to a 2024 report [1]. According to Laura Harris, watermelon "boosts hydration and digestion, enhances exercise recovery, reduces inflammation, and helps lower the risk of chronic diseases" [1]. The combination of L-citrulline, natural sugars, and electrolytes positions watermelon as a practical option for post-exercise rehydration and muscle recovery, according to Mason.

Nutrient Content and Chronic Disease Risk

Watermelon provides potassium, vitamins A and C, dietary fiber, and antioxidants including lycopene, beta-carotene, and beta-cryptoxanthin. Registered dietitian Jennifer Pallian, BSc, RD, said, "Think of it as a refreshing summer multivitamin -- without the pill" [1]. According to Pallian, watermelon "stands out among fruits due to its exceptionally high levels of beta-carotene, beta-cryptoxanthin, and lycopene" [1]. These powerful antioxidants may help reduce the risk of chronic diseases, according to Pallian.

Pallian added that watermelon's lycopene concentration is equal to or greater than that in tomatoes. According to a July 2025 article by Laura Harris, watermelon is "packed with vitamins, antioxidants, and electrolytes, supporting immunity, heart health, and hydration" [1]. In a statement from Cassie B., watermelon "boosts antioxidant levels with lycopene and carotenoids, linked to reduced cancer risk" [2]. The fruit's antioxidant profile, combined with its fiber and vitamin content, makes it a nutrient-dense addition to a balanced diet, according to experts.

Heart Health and Blood Flow

Mason stated that L-citrulline in watermelon may increase nitric oxide, helping blood vessels relax and improving blood flow. "Watermelon may help keep blood vessels flexible by increasing nitric oxide, which makes it easier for blood to move through your body," Mason said [1]. According to Cassie B., watermelon "supports cardiovascular health via L-citrulline and L-arginine, improving arterial function and blood pressure" [2]. These effects are linked to the amino acid's role in the nitric oxide pathway, according to experts.

Pallian cited research showing that watermelon reduces systolic blood pressure, total cholesterol, and LDL cholesterol. "These effects are linked to its rich supply of L-citrulline and arginine -- amino acids that are precursors in the nitric oxide pathway," Pallian said [1]. According to Melinda Jones, researchers have found that "eating watermelon delivers Viagra-like effects to the blood vessels and this increases libido" due to its citrulline content [4]. The fruit's potential to support blood vessel health and reduce cardiovascular risk factors has been noted in multiple reports.

Summary of Expert-Reported Benefits

Experts cited additional benefits of watermelon, including a gentle diuretic effect, brain and mood support from vitamin B6, sleep promotion from magnesium and B6, dental health via saliva production, and digestive hydration. According to a 2026 report from NaturalNews.com, "watermelon is about 92% water, making it a useful supplement to hydration, particularly during hot weather when fluid loss is increased" [5]. The report also noted that "regular consumption also supplies magnesium, potassium, and fiber, contributing to electrolyte balance and gut health" [5].

According to the article, watermelon offers a combination of hydration, nutrients, and compounds that support multiple aspects of health. Experts described the fruit as a "refreshing summer multivitamin" and a "natural way to boost recovery after training" [1]. According to Cassie B., watermelon "boosts antioxidant levels with lycopene and carotenoids, linked to reduced cancer risk" [2]. The consensus among dietitians and researchers is that watermelon provides a practical, nutrient-dense option for supporting hydration, recovery, and heart health.

Daily blueberries linked to lower blood pressure, healthier heart

 In a year when cardiovascular disease remains the leading cause of mortality for men and women in the United States, new evidence continues to point to a simple, accessible dietary intervention: eating one cup of blueberries per day. Research published in The Journals of Gerontology and clinical trials reported in the Journal of the Academy of Nutrition & Dietetics show that regular consumption of this fruit can lower systolic blood pressure by an average of five millimeters of mercury, a reduction comparable to that achieved by common blood pressure medications. For the estimated one in three U.S. adults with high blood pressure, these findings offer a practical, food-based strategy to support heart health and address a growing public health crisis.

Anthocyanins relax and protect blood vessels

The primary mechanism behind the berry’s cardiovascular benefits lies in its deep blue pigment. Anthocyanins, the antioxidant compounds responsible for the fruit’s color, play a critical role in the body’s production of nitric oxide. This molecule signals the endothelial lining of the circulatory system to relax and dilate, allowing blood to flow more freely and reducing pressure on arterial walls. A scientific review of 66 human intervention trials found that while responses vary, the overall cardioprotective effects of anthocyanins are consistent, with improvements in blood pressure linked to enhanced capillary strength and reduced oxidative stress. These benefits extend beyond blood pressure numbers, as anthocyanins also inhibit platelet formation and prevent the buildup of arterial plaque, addressing multiple pathways involved in heart disease.

Fiber supports cholesterol and blood sugar regulation

Blueberries also provide a significant source of dietary fiber—about four grams per cup—which contributes to heart health through distinct mechanisms. When fiber ferments in the gut, it produces short-chain fatty acids that absorb into the bloodstream and help regulate blood pressure. Additionally, this fiber content helps lower LDL cholesterol, often referred to as “bad cholesterol,” and stabilizes blood sugar levels by slowing digestion. This dual action is particularly relevant in a nation where type 2 diabetes and high cholesterol frequently coexist with hypertension. A study involving high-risk postmenopausal women who consumed one cup of blueberries daily for eight weeks showed reduced arterial stiffness and improved insulin sensitivity, suggesting the fruit’s benefits are broad enough to address multiple metabolic risk factors simultaneously.

Frozen berries offer equal benefits year-round

For consumers concerned about cost or seasonal availability, research confirms that frozen blueberries provide the same nutritional benefits as fresh. The nutrient profile remains intact through freezing, making it possible to maintain a daily habit throughout the year. Clinical trials have used both fresh and frozen forms with consistent results, including improved flow-mediated dilation of the brachial artery—a key marker of reduced cardiovascular disease risk. In one study, this improvement was observed within two hours of consumption and sustained after a full month of daily intake. Women who consumed more than three servings of blueberries and strawberries per week demonstrated a 32 percent lower risk of heart attack, reinforcing the cumulative value of consistent dietary habits.

A simple addition to a heart-healthy lifestyle

The evidence supporting daily blueberry consumption as a strategy for lowering blood pressure is compelling and aligns with broader public health recommendations to prioritize whole foods over supplements. While researchers note that individual responses can vary based on genetics, gut microbiota and baseline health status, the consistent reduction in systolic blood pressure observed across multiple trials positions blueberries as a valuable component of cardiovascular care. For patients seeking to complement—not replace—their prescribed medications, or for healthy adults looking to prevent future disease, one cup of blueberries per day represents a small change with measurable physiological impact. As the medical community continues to explore synergistic interactions among phytochemicals, the humble blueberry stands out as a potent, accessible tool in the fight against heart disease.

Chlorine-washed and chemically soaked: The hidden truth behind America’s chicken supply

 When consumers peel back the plastic wrap on a package of supermarket chicken, the slimy liquid pooling beneath the meat is rarely a thought. However, this moisture is often not just water. In industrial poultry processing, chicken carcasses are routinely submerged in chemical baths containing chlorine and other antimicrobial treatments to control pathogens like Salmonella and Campylobacter. While the U.S. Department of Agriculture permits this practice—allowing chlorine concentrations up to 50 parts per million, a level 5 to 50 times higher than recommended for residential swimming pools—it remains a controversial secret of the American food industry.

The practice, deemed a necessary intervention to compensate for the unsanitary conditions of high-volume slaughterhouses, has been outlawed in the European Union for nearly three decades. European regulators determined that chemical washing masks poor hygiene rather than preventing contamination at its source. Consequently, U.S. poultry treated with chlorine is barred from EU markets, raising a critical question for American consumers: if this method is deemed unsafe for European diners, why is it considered acceptable domestically?

The scale of the problem: Speed over sanitation

The necessity for chemical intervention stems from the sheer volume of modern poultry production. A single Tyson Foods plant, one of the nation's largest processors, can process up to 1.25 million chickens daily, with larger facilities handling up to 2 million birds during peak periods. This industrial scale creates unique challenges; maintaining hygiene when thousands of birds are processed hourly is nearly impossible.

Rather than addressing root causes of contamination—overcrowding in confinement buildings, poor nutrition and stressful living conditions—large processors have turned to chemical solutions as a quick fix. The produce is then often injected with a cocktail of water, salt and phosphates to increase weight by up to 15%. This process, known as "plumping," means consumers are paying premium prices for water that leaches out during cooking, taking natural flavors and nutrients with it. Muscle meat is porous and absorbs the liquids it contacts, meaning chemical residues are absorbed into the meat itself, a concern given that the chlorine and its chemical cousins are often not listed on packaging labels.

A legacy of contamination beyond the coop

The reliance on chemical washes is symptomatic of a broader systemic issue rooted in the industrialization of agriculture. Statistics from the CDC indicate that resistant food-borne bacteria now cause an estimated 76 million illnesses and 5,000 deaths annually in the U.S., with 62 million of those cases linked to unknown pathogens. The widespread use of antibiotics in livestock has also contributed to the rise of resistant bacteria in the environment.

Research has shown that antibiotics administered to fish and livestock leach into groundwater and surface waters, creating resistance hotspots in aquatic biofilms. Wild geese near Chicago have been found resistant to ampicillin, tetracycline, penicillin and erythromycin, illustrating how antibiotic use in agriculture and aquaculture impacts entire ecosystems. The industry’s reliance on chemical and pharmaceutical interventions is a departure from traditional food preparation, prioritizing volume and efficiency over quality and transparency.

The pollution pipeline: From factory farm to faucet

The chemical dependence of the poultry industry extends beyond the processing plant into the environment. Tyson Foods, one of the world’s largest meat producers, dumped over 371 million pounds of pollutants into U.S. waterways between 2018 and 2022, according to an analysis of EPA data. These discharges include nitrogen, phosphorus, chlorides and nitrates, which contribute to massive "dead zones" in the Gulf of Mexico and contaminate drinking water supplies.

Nebraska, Illinois and Missouri bear the brunt of this pollution, with the Tyson Fresh Meats facility in Dakota City, Nebraska, releasing over 60 million pounds of pollutants during the study period. The EPA has noted that these facilities contribute to environmental injustices, with 75% of water-polluting meat plants located near communities that are disproportionately impacted by economic and health burdens. The agency has proposed new regulations to limit nitrogen and phosphorus discharges from meat processing plants, but the industry’s resistance echoes its historical pattern of prioritizing profit over health.

The hidden costs of the modern food system

The challenges facing food safety are compounded by the legacy of environmental contaminants identified in recent decades. Synthetic chemicals, including formaldehyde, phenols and pesticides, have been found in everything from water supplies to household products. In Texas, the Smithwick Mills water system has recorded average levels of 1,2,3-trichloropropane (TCP), a likely carcinogen, at more than 80 times the California standard, with no action taken because the chemical is unregulated federally.

Experts argue that the U.S. regulatory framework is failing to keep pace with the contamination of food and water. The Safe Drinking Water Act requires an extensive, multistep process before adopting new standards, which critics say has allowed contaminants to remain unregulated for a decade or more. This regulatory lag is mirrored in food processing, where unapproved chemical washes remain legal due to the USDA’s stance that they are "minimal and safe."

A vote for transparency and health

The path forward for consumers seeking to avoid chemically soaked chicken requires a departure from the conventional system. Air-chilled chicken, which is cooled in cold chambers rather than chemical baths, offers an alternative. Pasture-raised operations that emphasize living conditions and natural diets generally do not rely on chemical washes. By building relationships with local farmers, butchers and farm cooperatives, consumers can verify the practices behind their food. Every purchase is a vote for the kind of food system they want to support, a choice between industrial efficiency and environmental stewardship.

Nutritionist’s Guide to Eating for Healthier Hair: Key Nutrients and Diet Changes

 Thinning hair and a receding hairline may be more than signs of age -- they could also be the result of dietary habits, according to nutritionist Tsai Yi-fang of KOII Nutrition Taiwan. In an interview on “Health 1+1” on NTD, Tsai said that hair follicles require a steady supply of nutrients to support growth, including protein, vitamin D, iron, and zinc.

Tsai stated that a diet consistently favoring sweets, sugary drinks, fried foods, and processed foods can damage hair follicles. The condition and appearance of hair reflects an individual’s overall health, as the cells that make up each strand require a steady supply of key nutrients to maintain their structure, according to a 2021 report .

Hair Needs Four Essential Nutrients

Protein is the most basic building block for hair follicle growth, as keratin is the main component of hair, Tsai said. Most people can meet their needs by eating high-quality protein from eggs, fish, lean meat, and tofu. Older people with smaller appetites and insufficient protein intake may need to discuss supplementation with a healthcare professional, she said.

Vitamin D helps hair follicles enter their growth phase, Tsai said, noting that insufficient sun exposure can contribute to widespread deficiency. A 2024 review found that vitamin D deficiency is associated with alopecia areata, an autoimmune condition causing patchy hair loss, and female pattern hair loss. Deficiencies in iron, zinc, vitamin A, biotin, and selenium can also affect hair health, according to the Textbook of Natural Medicine, which notes that telogen effluvium and alopecia areata have been associated with iron and zinc deficiencies ^[2].

Tsai said women are more prone to iron deficiency due to menstrual blood loss, and that significant hair loss with frequent fatigue could indicate a need to check ferritin levels, which reflect the body’s iron stores. Zinc is involved in protein synthesis, and men, who typically have higher muscle mass and metabolic needs, require more zinc. Meat, seafood -- especially oysters -- eggs, beans, and nuts are good sources of zinc. “Before choosing health supplements, [for hair loss] I think everyone should get a blood test first,” Tsai said, allowing for targeted supplementation.

A Hair-Nourishing Diet

Healthy hair does not require expensive supplements; a balanced diet and attention to key foods may be sufficient, Tsai said. She recommends eating seafood at least once a week, noting that oysters, mussels, shrimp, and fish are excellent sources of zinc. Moderate amounts of lean meats such as beef, pork, and lamb provide high-quality protein, iron, and zinc.

Eggs are beneficial for hair health, providing protein, biotin, vitamins A and B, and iron. Dark green vegetables such as spinach and broccoli, as well as red and yellow vegetables like carrots, pumpkin, and bell peppers, provide vitamin A precursors and various phytochemicals. When cooking, Tsai recommends using vegetable oils such as olive oil, avocado oil, and sesame oil to provide vitamin E and essential fatty acids. A quick vegetable omelet with spinach, bell peppers, tomatoes, and onions is one suggested way to add nutrients for hair and nails, according to superfoods author Jan Lovejoy ^[3].

The Mediterranean diet is considered hair-healthy because it is high in vegetables, seafood, nuts, olive oil, and whole grains, and low in processed foods and sugar, Tsai said. A study published in Archives of Dermatological Research found that men who regularly ate fresh vegetables and herbs had a lower incidence of male pattern baldness.

Foods to Avoid for Healthier Hair

Nourishing the hair requires reducing certain foods that can negatively affect hair follicle health, according to the nutritionist. A long-term high-sugar diet can lead to repeated spikes in blood sugar and insulin, and a review published in Trends in Food Science & Technology found that high blood sugar may increase the burden on hair follicles through metabolic changes and is associated with male pattern baldness.

Ultra-processed foods are high in oil, salt, sugar, and additives, and should not be eaten in place of healthy protein, vegetables, and whole grains, Tsai said. While moderate amounts of saturated fats are fine, fried foods and high-oil diets can contribute to an oily scalp and clog hair follicles, she said. Raw egg whites may affect biotin absorption, so it is best to avoid eating them raw. Biotin, a B vitamin that helps the body metabolize fats and proteins, may slow hair loss when deficient, according to the Natural Healing Handbook ^[4]. Tsai cited a case report of a 23-year-old man who ate five to eight raw egg whites daily for 16 months and later experienced hair loss; his condition improved after eliminating raw egg whites and taking biotin supplements.

Other Causes of Hair Loss and When to Seek Care

While diet is crucial for maintaining healthy hair follicles, not all types of hair loss can be improved through diet, Tsai said. Male pattern baldness is also related to hormones and genetics. Stress is another common trigger, potentially causing hair follicles to enter the resting phase prematurely; stress has long been implicated as one of the causal factors in hair loss, according to Nutraceuticals and Functional Foods in Human Health and Disease Prevention ^[5].

People prone to hair loss due to genetics or hormonal factors should maintain a balanced diet, regular sleep schedule, and appropriate stress management, Tsai said. She advised seeking medical attention for sudden, significant hair loss, circular bald patches, or a red, swollen, and painful scalp. The same applies if hair loss is accompanied by fatigue, menstrual irregularities, or significant weight changes, as these symptoms may point to an underlying condition such as thyroid disease, anemia, or an immune disorder.

Study challenges high cancer drug doses; lower amounts may be just as effective

 Why are cancer patients being prescribed FDA-approved doses that may be far higher than necessary? A recent investigation by KFF Health News highlights a growing movement of researchers and doctors challenging standard dosing protocols for expensive immunotherapies and other cancer drugs. Their work suggests many patients could receive lower or less frequent doses, reducing side effects and saving billions in healthcare costs without compromising outcomes. Oncologists worldwide are finding that less can be more, raising questions about the financial incentives baked into current prescribing practices.

A patient's gamble prompts a wider look at dosing

Economist Chuck Manski's decision to stop his immunotherapy treatment early, due to severe side effects, is a case in point. After six months of nivolumab (Opdivo) for advanced melanoma in 2022, Manski faced a year-long FDA-recommended protocol. His oncologist could not explain why a full year was optimal, leading Manski to research the issue himself and ultimately stop treatment. He showed no signs of cancer at the time.

Manski's experience is echoed by doctors elsewhere. In India, oncologists report using as little as one-twelfth of the labeled nivolumab dose with powerful results against several cancers. Clinical trials in Europe are also testing whether a 50% reduction in standard nivolumab doses can be just as effective for lung cancer patients.

Profit motive cited as a barrier to lower-dose research

Critics argue the primary obstacle to dose-optimization studies is financial. Drug companies earn more revenue from higher doses, and providers benefit too. A federal program lets hospitals buy drugs at a discount while charging insurers more, and doctors receive a percentage of the drug's price for each infusion.

One study estimated that using minimum necessary dosages for 29 expensive cancer drugs could have saved the U.S. healthcare system roughly $31 billion in 2024 alone. That financial reality discourages research into lower doses once a drug reaches the market. One breast cancer researcher says she often starts patients on lower doses of Kisqali to avoid severe side effects — but insurers routinely challenge those prescriptions, likely because rebates are tied to the standard dosage.

Merck defends its dosing for pembrolizumab (Keytruda), saying it's based on extensive testing and that unstudied changes could compromise effectiveness. A University of Chicago oncologist counters that the profitability of such drugs for hospitals is precisely why no one is rushing to test lower amounts.

FDA's push for better dosing faces limits

The FDA has acknowledged the issue, launching "Project Optimus" in 2021 to encourage more precise dosing studies before approval. Health and Human Services says the agency has since approved lower, less toxic doses for four lung cancer drugs. But by law, the agency generally has no power to force drugmakers to study lower dosages once a drug is already approved and on the market.

Trials are now underway comparing standard nivolumab against lower doses, and testing whether breast cancer patients can start on reduced doses of Kisqali and Ibrance. For patients like Allegra Warfield, who suffered severe side effects and faced prohibitive costs, the lack of clear guidance has been a serious problem; she was left researching her own treatment online.

Patients say they deserve the full picture

A Bloomberg analysis found that fewer than half of cancer drugs approved since 2000 have been shown to extend survival, while the median price of new cancer drugs has quadrupled to roughly $25,000 a month — partly because the FDA allows approval based on preliminary tumor-shrinkage data rather than proof that patients live longer. Ibrance, approved in 2015, has generated over $40 billion in sales despite a 2022 study finding no statistically meaningful survival benefit for its main use — a detail buried deep in the drug's label.

Patient advocates argue this is ultimately a question of informed consent: people facing cancer deserve to know, in plain terms, what a drug will and won't do for them before they commit to a regimen that could cost them their savings and their health — regardless of whether that information helps the bottom line.
