A recent randomized trial involving 48 healthy adults indicates that adopting a vegan diet for just four weeks can alter DNA methylation patterns, potentially reducing inflammation and slowing biological aging markers. While the study found shifts in immune cell composition and gene activity, experts caution that these preliminary results do not guarantee long-term health benefits or extended lifespan.
A Nature Communications study of about 200 Orthodox Christians who regularly fast from meat and dairy, plus a non-fasting control group, shows that short-term animal-product restriction can alter gene expression and metabolic markers—including FGF21—with signs of adipose tissue beiging and a genotype-linked change in the LBR gene, highlighting a complex diet–genetics relationship and the need for further research.
In a small 4-week, isocaloric study of 48 healthy adults, those on a vegan diet showed a statistically significant ~1.7-year reduction on the PhenoAge biological aging clock, while a GrimAge clock showed a smaller, non-significant shift and a chronological-age clock trended higher. Immune-cell changes (lower neutrophils, higher CD4+ T cells) aligned with blood tests. Genome-wide DNA methylation shifts occurred but most did not survive correction for multiple comparisons, making results preliminary. Limitations include the small sample size and use of a less-clean vegan diet (allowing processed foods); researchers plan longer, more controlled studies to confirm findings.
An inquest into Swansea University student Georgina Owen’s death found that a vitamin B12 deficiency, likely caused by her vegan diet and a six-month lapse in supplementation, contributed to a psychiatric decline and delusional beliefs, culminating in suicide; experts caution that vegans should ensure adequate B12 intake through fortified foods or supplements.
A national Israeli study of nearly 1.2 million infants shows vegan and vegetarian diets support normal growth through age two, with only minor early differences that fade by 24 months when diets are properly planned and access to nutrition counseling is available.
A pooled analysis of 1.8 million adults from nine prospective cohorts across the UK, US, Taiwan, and India found diet‑related differences in cancer risk. Compared with meat eaters, poultry eaters had a lower prostate cancer risk; pescatarians had lower colorectal, breast, and kidney cancer risks; vegetarians had lower risks of pancreatic, breast, prostate, kidney cancers and multiple myeloma but a higher risk of oesophageal squamous cell carcinoma; vegans had a higher risk of colorectal cancer. The authors caution that results may not generalize and could be influenced by residual confounding and misclassification in diet groups.
A new study finds that a low-fat vegan diet leads to greater weight loss than the Mediterranean diet, even when including foods labeled as 'unhealthy' in plant-based scoring systems, mainly due to avoiding animal products and reducing oils and nuts.
A new study suggests that a low-fat vegan diet may be more effective for weight loss than the Mediterranean diet, emphasizing the benefits of replacing animal products with plant-based foods to enhance satiety and reduce calorie intake.
Two British twins conducted a three-month experiment comparing vegan and omnivorous diets, revealing that the vegan diet increased energy and improved gut health, while the omnivorous diet supported muscle growth, highlighting the different impacts of each diet on the body.
Jan Heemskerk, former Dutch Playboy editor, was diagnosed with Parkinson's in 2021 and has since become an advocate for awareness and lifestyle changes, including adopting a vegan diet and engaging in strength training, to manage the disease and highlight environmental factors contributing to Parkinson's.
The article outlines seven common mistakes vegans make that can lead to fatigue, including under-eating calories, neglecting vitamin B12 and iron, consuming processed carbs, ignoring omega-3s, sacrificing sleep, and not monitoring health data. It offers practical tips to address these issues, emphasizing balanced nutrition, supplementation, sleep hygiene, and regular health check-ins to maintain energy and well-being on a vegan diet.
The article shares a personal journey of overcoming fatigue, bloating, and mental fog caused by an improperly managed vegan diet. It emphasizes the importance of focusing on whole, minimally processed foods, ensuring adequate protein, supplementing B12 and iron, gradually increasing fiber intake, and listening to one's body rather than following social media trends. With these adjustments, the author regained energy, clarity, and health, highlighting that veganism is most effective when approached with intention, balance, and self-compassion.
A study funded by the beef industry intended to show the superiority of animal protein over plant protein instead found no significant difference in muscle protein synthesis between the two. The study, which involved 17 women consuming different protein sources, revealed that even "incomplete" plant proteins can effectively stimulate muscle growth. This adds to the growing body of evidence supporting the nutritional adequacy of plant-based diets, despite industry efforts to promote animal protein.
Sam Bankman-Fried, the FTX founder facing a 25-year sentence, may struggle to maintain his vegan diet in prison, particularly if he is sent to a facility with limited vegan options. The judge recommended a low- or medium-security prison, taking into account Bankman-Fried's wealth and autism diagnosis. A prison consultant suggested that his safety could be at risk in a medium-security facility, and food options are likely to be an issue regardless of the prison's security level.
A groundbreaking study by the Physicians Committee for Responsible Medicine reveals that a low-fat vegan diet can reduce insulin needs and improve insulin sensitivity, glycemic control, cholesterol levels, kidney function, and weight for people with type 1 diabetes. The 12-week study, the first of its kind, showed that participants on the vegan diet reduced insulin needs by 28% and increased insulin sensitivity by 127%, while also experiencing weight loss and improved cholesterol levels. The findings suggest that a low-fat vegan diet may be beneficial for managing blood sugar levels and reducing cardiovascular risk in individuals with type 1 diabetes.
