A recent study published in Neurology on 11 February 2025, led by researchers from Brigham and Women’s Hospital, has investigated the relationship between long-term red meat consumption and the risk of dementia and cognitive decline in U.S. adults. The study utilised data from the Nurses’ Health Study and the Health Professionals Follow-Up Study, encompassing approximately 170,000 participants…
Introduction Chronic pain is a widespread issue that significantly impacts quality of life and healthcare systems. While obesity is a well-documented risk factor for chronic pain, recent evidence suggests that other factors, such as diet quality, may also play a role. A recent study explores the relationship between diet quality and body pain in adults,…
Earlier this year I wrote about the results of a large study evidencing the association between artificial sweeteners and cancer risk. Debras et al. used the same cohort (Nutrient-Sante) of over 100,000 participants. But this time, they looked at the association between artificial sweeteners and cardiovascular disease risk. The study was published in The British…
Unfortunately there is currently an absence of curative and preventative interventions for Alzheimer’s Disease (AD). Last year, Panza et al. reviewed the research on the links between vitamin D and AD. Low vitamin D levels have been associated with an accelerated decline in cognitive functions. They have also been associated with the development of chronic…
Valter Longo et al. recently published a paper that examined research on the relationships between nutrition, health and longevity. Here are some of the main components of a longevity diet: mid to high carbohydrate intake (45-60%) – mostly non-refined fat intake (25-35%) – mostly plant-based low protein intake (10-15%) – mostly plant-based but includes regular…
Our immune system protects us from pathogens like viruses, bacteria, cancerous cells, etc. and it can be separated into 2 distinct branches: the innate immune system and the adaptive immune system. Our innate immune system uses cells such as macrophages, neutrophils and mast cells to mount a fast, generic response to pathogens. Inflammation is the…
About a year ago Sutton et al. published a study that showed that intermittent fasting has benefits that are independent of food intake and weight loss. Their trial tested the effects of 5 weeks of “early time-restricted feeding” (eTRF) on 8 men with pre-diabetes. The subjects were asked to start breakfast between 6:30-8:30 and to…
A few months ago Lopez-Minguez et al. reviewed studies looking at the effect of meal times on obesity and metabolic risk. Their findings are summed up in the following points: skipping breakfast is linked to obesity eating a large breakfast (within 2hrs of waking) decreases the probability of being obese by 50% a late lunch…
Faraco et al. recently discovered mechanisms by which salt-rich diets can lead to cognitive dysfunction in mice. An increase in dietary salt led to a deficiency of nitric oxide in cerebral blood vessels. As nitric oxide is a vasodilator, the reduced levels resulted in decreased cerebral blood flow. In addition, nitric oxide deficiency causes the…
Research published earlier this month in the European Journal of Nutrition questions the health benefits of the Paleolithic diet. The Paleo diet claims to mimic the diet of our ancestors. It’s high in meat, fruits, vegetables, nuts and seeds but avoids dairy, legumes and grains. Genoni et al. studied a group of about 100 people…
