For decades, nutrition debates have often centered on whether people should cut carbohydrates or cut fat. A new study examined how low-carbohydrate and low-fat diets were associated with heart disease risk when the quality and sources of the foods people ate were taken into account. The researchers analyzed data from 198,473 men and women in three long-running health studies in the United States. Participants were free of diabetes, cardiovascular disease, and cancer at the start, and completed detailed diet questionnaires about every four years over periods spanning more than 30 years. Rather... cardiovascular diet heart disease carbohydrates fat
Read more[toc position='left'] Biological aging clocks are among the most important tools in modern longevity science. They attempt to answer a deceptively simple question: can we measure how fast a person is aging biologically, rather than just counting the number of years they have been alive? The answer is yes—but with important caveats. Epigenetic clocks use patterns of DNA methylation, a chemical tagging system on DNA, to estimate different aspects of aging. Some clocks estimate chronological age. Others predict disease risk, mortality risk, or the current pace of biological aging. This means biol... epigenetics aging telomeres genetics stem cells omega-3 dna damage biomarkers vitamin d senescence multivitamin

Watch now[toc] Alcohol is one of the most heavily used and abused drugs. It's also a very controversial topic, in part because alcohol plays such a large role in societies and cultures around the world. For many, it's a normal part of daily life. There is also a lot of confusion about alcohol. There's no doubt that alcohol can have a personal and public health impact. On the other hand, research in the last few decades suggests that not only may a moderate intake of alcohol not be harmful, but it might also be protective against certain diseases. This idea is heavily debated, and conflicting evidence h... cancer cardiovascular alcohol brain alzheimer's diabetes breast cancer
Read moreEating walnuts prevents premature death and extends life expectancy. Walnuts are a nutrient-dense food, rich in omega-3 fatty acids, protein, fiber, and many vitamins and minerals. Evidence suggests that consuming walnuts as part of a healthy diet improves cognitive function (https://www.sciencedirect.com/science/article/abs/pii/S1043661817311751) and cardiovascular health (https://academic.oup.com/jn/article/144/4/547S/4571627?login=true) and reduces the risk of developing certain types of cancer (https://www.tandfonline.com/doi/abs/10.1080/01635581.2014.956246).

Read moreMaintaining a systolic blood pressure of 120 or less may protect against dementia and cognitive decline. Nearly two-thirds of adults living in the United States have hypertension (high blood pressure), defined as having a systolic pressure of 130 or higher or a diastolic pressure of 80 or higher. Hypertension damages small blood vessels in the eyes, kidneys, and other tissues (https://www.sciencedirect.com/science/article/abs/pii/S027263868580072X), increasing the risk for disease and dysfunction. A 2019 study found that intensive blood pressure control in patients with hypertension reduces t... brain aging dementia blood pressure
Read moreCurrent dietary guidelines for people living in the United States recommend following a health dietary pattern that is rich in nutrient-dense foods to promote health and prevent chronic disease. Findings from a recent study demonstrate that including mushrooms as part of a healthy dietary pattern provides many essential nutrients. Mushrooms are edible fungi, generally categorized as vegetables in the human diet. They are rich sources of many vitamins and minerals, including B vitamins, potassium, and selenium. When grown in the presence of ultraviolet light, mushrooms are good sources of vita... nutrition micronutrients

Early nutritional deficits are intrinsically linked to impaired mental and physical growth. Consequently, the risk of developing metabolic and cardiovascular diseases such as obesity, diabetes, and hypertension in childhood and later life is likely determined by early feeding and nutritional status. Breastfeeding is the biologically superior way to feed an infant. The American Academy of Pediatrics recommends exclusive breastfeeding for the first six months of an infant's life ... cancer breast cancer circadian rhythm nutrition brain microbiome heart disease diabetes inflammation alcohol stem cells immune system development intelligence
