Neurodegenerative diseases like Alzheimer's disease and frontotemporal lobar degeneration are characterized by the abnormal buildup of tau, a protein that damages brain cells and drives cognitive decline. A recent study found that tau-related disorders in both fruit flies and humans are closely linked to neuronal accumulation of glycogen—the stored form of glucose—and that breaking down this glycogen substantially reduces tau-related brain damage. In this study, researchers used fruit flies genetically engineered to produce a harmful form of human tau protein, as well as neurons derived from h... alzheimer's blood sugar brain dementia metabolism
Read moreMeal timing may influence more than just hunger—it can affect our sleep, mood, and day-to-day functioning. Time-restricted eating, a strategy that limits food intake to a specific window each day, has shown promise for weight loss and improved metabolic health, and may also support other aspects of well-being. A recent study found that people who followed time-restricted eating lost about 3 kilograms (roughly 6.5 pounds) more than those who didn't, regardless of whether they ate early, late, or chose their own schedule. Researchers provided 197 adults who had overweight or obesity with guidanc... time-restricted eating weight loss
Read moreNitrates from vegetables—especially leafy greens and beets—are generally beneficial, due to their synergistic effects with antioxidants and other protective compounds. In contrast, nitrates in processed meats can form harmful byproducts during cooking or digestion and are linked to higher risks of chronic disease. A recent study found that people who eat more nitrate from vegetables show fewer signs of early brain changes associated with Alzheimer's. Researchers analyzed data from more than 500 cognitively healthy older adults living in Australia. They estimated nitrate intake from food freque... alzheimer's diet
Read moreBody art is more popular than ever, with roughly one-third of people in the U.S. having at least one tattoo. However, tattoo inks often contain harmful chemicals, including carcinogenic pigments and metals. A recent study found that people with tattoos are 21% more likely to develop malignant lymphoma. Researchers conducted a case-control study among roughly 1,400 people diagnosed with malignant lymphoma ("cases") in people aged 20 to 60 over 10 years. They matched the cases with age- and sex-matched people without cancer ("controls") from the general population. Then, they gathered informati... cancer immune system
Read more[toc position='right'] When we engage in high-intensity exercise, our muscles become mini biochemical laboratories (https://www.youtube.com/watch?v=YXl1evV_spo), synthesizing compounds like lactate and myokines that circulate throughout the body and travel to our organs, where they exert a variety of signaling effects, including the synthesis of brain-derived neurotrophic factor (BDNF) (https://bdnfprotocols.com/)in the brain. Some of these molecules have anti-cancer properties. Vigorous exercise is also the most potent way to increase your VO2 max, also known as cardiorespiratory fitness, wh... exercise brain bdnf aerobic cardiovascular mortality aging exercise snacks
Read more[toc position='left'] Introduction Magnesium is an essential dietary mineral. It plays critical roles in myriad physiological processes, serving as a cofactor to more than 300 enzymes in the human body and maintaining the integrity of cellular structures and DNA. Magnesium deficiency is widespread, affecting more than half of people in the U.S. and increasing the risk of many chronic conditions, including cancer, metabolic disorders, and neurodegenerative diseases. At a glance, magnesium participates in: Enzymatic reactions, serving as a cofactor for more than 300 enzymes involved in variou... magnesium brain nutrition supplements micronutrients

Watch nowSedentary behavior is associated with an increased risk of many chronic diseases. Evidence suggests that "exercise snacks" – brief, isolated intervals of vigorous exercise, each lasting less than one minute and typically performed multiple times throughout the day – may counter the harmful effects of sedentary behavior. A 2022 study found that vigorous stair-climbing increased participants' peak oxygen uptake by approximately 5 percent. The study involved 24 healthy, sedentary young adults. For six weeks, half of the participants engaged in three bouts of vigorous stair climbing (60 steps in ... exercise aging diabetes aerobic exercise snacks
Read moreMelamine, its derivatives, and other nitrogen-containing compounds are ubiquitous in the environment. Despite their known toxicity, these compounds are used in a variety of household products (https://ec.europa.eu/health/scientific_committees/consumer_safety/docs/sccs_o_090.pdf), including dishware, cleaning products, cosmetics, tattoo ink, and many others. Findings from a recent study suggest that pregnant females are exposed to a wide variety of these compounds via common household products. Toxic environmental exposures can have serious, harmful effects on pregnant females and developing f... pregnancy development pollution environment tobacco
Read moreThe average life expectancy of people living in the United States is roughly 79 years. Several factors influence how long a person lives, however, such as diet, physical activity, and smoking. A new study suggests that mental stress shortens life expectancy by nearly three years. Mental stress can affect the immune, digestive, cardiovascular, sleep, and reproductive systems, eliciting a wide range of symptoms, including headaches, sleeplessness, sadness, anger, or irritability. Prolonged stress can promote continued strain on the body, contributing to serious health problems, such as heart di... diet aging depression blood pressure dairy
