[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
Read more[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

Watch now[toc position='left'] The blood-brain barrier comprises various membranes that separate the central nervous system (CNS) and the peripheral circulatory system. The purpose of this barrier is to allow the passage of nutrients and cell signals from the bloodstream to nerves and supporting cells in the CNS while excluding harmful substances. Genetic predispositions, environmental exposures, and aging may weaken the integrity of this barrier, allowing endotoxins and inflammatory immune cells to infiltrate the brain, contributing to accelerated brain aging and the risk of neurodegenerative diseases... omega-3 immune system blood-brain barrier brain alzheimer's gut obesity
Read more[toc position='left'] Thymic involution is the process by which the thymus shrinks with age and produces fewer T cells, impairing immunity and increasing the risk of infection in older adults. In addition, thymic involution increases the risk of cancer and autoimmunity with age. However, research has identified some of the mechanisms of thymic involution and highlighted possible strategies to improve immunity: By activating PPAR-gamma, a protein that regulates fat metabolism, caloric restriction reduced the rate of thymic involution in mice and increased the number and diversity of circulatin... thymic involution immune system thymus autoimmunity
Read more[toc position='left'] Background Collagens are major structural proteins in numerous body tissues, including tendons, ligaments, cartilage, skin, blood vessels, muscles, gut tissue, and dentin.[ref doi='10.1101/cshperspect.a004978'] They are the most abundant proteins in the body, comprising 30 percent of the total protein mass. The human body continuously manufactures collagens to maintain tissue structural integrity. However, aging drives a progressive decrease in protein synthesis and reduced capacity to produce new collagen.[ref doi='10.1016/S0047-6374(01)00337-2'] Collagens are also highl... interesting nutrition aging metabolism autoimmunity
