This “Glyphosate Replacement” May Be Even Deadlier.
A shocking report reveals that diquat, the herbicide now replacing glyphosate in many Roundup products, is about 200× more toxic and has been shown to damage organs, kill beneficial gut bacteria, and disrupt your gut lining—according to a Friends of the Earth analysis of EPA data.
The Collapse of Bees Is the Collapse of Our Food System.
USDA scientists have linked the worst U.S. honeybee die-off on record—a staggering ~60% colony loss—to pesticide-resistant Varroa mites spreading deadly viruses, notably deformed-wing viral strains A & B, and acute bee paralysis virus. Mites resistant to the last line pesticide, amitraz, failed to stop the viral spread—signaling a massive warning for bee health and ecosystems.
Tirzepatide Could Supercharge Weight Loss And Block Tumors.
A mouse study presented at ENDO 2025 by University of Michigan researchers found that tirzepatide (marketed as Mounjaro/Zepbound) caused ~20% weight loss in obese mice and dramatically slowed breast tumor growth, linking fat loss directly to improved cancer outcomes.
Women May Benefit Even More From Creatine Than Men.
A 2021 review in Nutrients by Smith‑Ryan et al. highlights that women have 70–80% lower natural creatine stores than men, making supplementation especially impactful for their health and performance.
Gluten Sensitivity Might Be Hiding Behind Your Skin Problems.
A recent EMJ Dermatology review shows that even without celiac disease or positive blood tests, non-celiac gluten sensitivity (NCGS) can still cause persistent skin issues like dermatitis herpetiformis, eczema, urticaria, psoriasis, and chronic rashes—symptoms that often improve after adopting a gluten-free diet.
Doctors Just Found 4 Hidden Roads to Alzheimer’s.
UCLA researchers uncovered four distinct “roadmaps” leading to Alzheimer’s by analyzing longitudinal health records from nearly 25,000 patients and validating findings in the All of Us cohort. These sequential diagnostic patterns predicted dementia better than any single risk factor.
Your Gut Bacteria May Be Making You Fat—Even On a Healthy Diet.
A July 2025 study from researchers in Japan found that certain gut bacteria may block weight loss—even when you eat well. People who ate a healthy diet but failed to lose weight had higher levels of Collinsella, a microbe linked to obesity and fat storage.
Religious Belief Cuts Risk of Depression, Anxiety, and Even Death.
A growing body of research from 2020 to 2025 shows that religion and spirituality offer powerful protection against depression, anxiety, and even chronic illness.
AI That Diagnoses Better Than Doctors Is Already Here.
A 2025 Microsoft study revealed that its AI system, MAI-DxO, correctly diagnosed 85% of complex medical cases—four times more accurately than experienced physicians.
Your Personality Type Could Be Sabotaging Your Fitness Goals.
A July 2025 UCL study in Frontiers in Psychology found that when people choose exercise types suited to their personality, they enjoy workouts more and experience greater stress relief than mismatched routines.
Betaine Shrinks Fat, Revives Gut, and Reboots Metabolism.
A 2025 animal study in Frontiers in Nutrition by Wang et al. found that giving high-fat–fed rats betaine (1.5% in drinking water) for 8 weeks led to less body fat, improved blood lipids (lower triglycerides, higher HDL), and better glucose tolerance—all without cutting calories.
Chronic Inflammation Doubles Your Risk of Depression & Anxiety.
A 2025 pooled cohort study of 1.56 million UK adults found that those diagnosed with autoimmune or chronic inflammatory conditions had a 86% higher likelihood of experiencing affective disorders (depression, anxiety, bipolar) compared to people without these conditions.
One Psilocybin Trip Can Deliver Two Years Of Depression Relief.
A 2025 study reported in ScienceDaily highlights that a single dose of psilocybin produced significant and sustained reductions in depression for cancer patients—lasting up to 2 years after treatment.
Oversleeping After Concussion Could Slow Recovery.
A 2025 cohort study of 291 Canadian youths (ages 10–18) found that sleeping more than 9.9 hours per night in the first two weeks after a concussion was linked to more severe symptoms and a higher risk of lingering effects at four weeks.
Early Plastic Exposure May Be Fueling Childhood Asthma.
A 2025 pooled cohort study involving 5,306 children from Australia, the U.S., and Canada, published in Journal of Exposure Science & Environmental Epidemiology, found that exposure to plastic-derived chemicals before age 5—such as phthalates and BPA—was linked to significantly higher rates of asthma and wheezing in childhood.
Could your Refrigerator Be Fueling Weight Gain?
A 2025 study by Zheng et al. used data from over 16,000 Chinese adults between 1997–2011. They found that simply owning a refrigerator was linked to a 39% increase in daily calorie intake, a rise in fat and protein consumption, and more processed food in the diet—alongside higher obesity risk, especially among older adults and men.
Waist-to-Height Ratio Beats BMI at Predicting Heart Failure Risk.
A 2025 analysis within the Malmö Preventive Project (1,792 adults, ~13 years follow-up) found that a higher waist‑to‑height ratio (WtHR)—not BMI—was strongly linked to incident heart failure.

Strong Antibiotics Could Make Pneumonia Worse.
A new study from The Lancet Infectious Diseases (2025) found that using broad-spectrum antibiotics to treat pneumonia may actually increase mortality risk in certain patients. These antibiotics can disrupt the microbiome, trigger harmful inflammation, and contribute to antibiotic resistance.
Weak Grip? You Might Be At Higher Risk For Asthma.
A 2025 study in Frontiers in Nutrition by Wen et al. found that low handgrip strength (HGS) and low relative handgrip strength (RHGS) were strongly linked to increased odds and risk of asthma—by up to 50% for those at the lowest quartile of grip strength.
