(https://www.foundmyfitness.com/newsletter) Protein is still (somehow) controversial. Should we restrict protein in favor of longevity and reducing cancer risk, or should we maximize our intake in favor of building muscle mass and enhancing performance? The answer lies somewhere in the middle. But one thing is for certain—the current recommendations don't accurately reflect the scientific evidence. That's why I sat down with Dr. Peter Attia as a guest on his ... aging cancer muscle strength protein exercise
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

That's what researchers observed when they gave dogs rapamycin—a drug traditionally used to treat certain cancers and prevent organ transplant rejection. The findings were striking: The dogs exhibited marked improvements in heart function, effectively reversing the age-related changes typically seen in aging. While these findings are remarkable, they add to a growing body of research indicating that rapamycin might enhance healthspan and promote longevity in various sp... aging autophagy metabolism immune system cancer drug

In recent decades, scientists have begun exploiting the body's responses to light with photobiomodulation, a non-invasive, light-based therapeutic technique. Photobiomodulation employs specific wavelengths of light (measured in nanometers, nm) to stimulate biological processes within cells and tissues, triggering a cascade of physiological responses. A growing body of evidence suggests that photobiomodulation has potential... bone skin brain depression arthritis

Senescence is a vital cellular process involved in embryonic development, wound healing, and cancer immunity; [ref doi='10.1242/dev.151837'] however, the accumulation of senescent cells is associated with diseases of aging such as cancer, cardiovascular disease, type 2 diabetes, Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, sarcopenia, and glaucoma.[ref doi='10.1016/j.cell.2017.05.015'] [ref doi='10.3390/ijms19102937'] ... neurodegeneration senescence aging

Common examples of aerobic exercises are walking, running, swimming, dancing, and other activities that increase heart rate and breathing. Exercise elicits a wide range of physiological changes in the body that improve cardiovascular, neurological, and metabolic health.

BDNF serves as a cell signaling protein, plays vital roles in numerous signaling pathways associated with a variety of disorders ranging from depression, (https://www.foundmyfitness.com/topics/depression) schizophrenia, and addiction to obesity and diabetes, and may serve as a hormone. It is perhaps best known for its influence on the formation, growth, survival, and development of neurons and for its role in mediating th... exercise omega-3 meditation brain alzheimer's parkinson's fasting memory interesting
Read more[toc position='left'] N-glycolylneuraminic acid, or Neu5Gc, is a sialic acid – a nine-carbon sugar molecule – produced by most nonhuman mammals. Sialic acids serve diverse roles, such as mediating cell-to-cell interactions, triggering cell signaling cascades, and binding to pathogens.[ref doi='10.1016/j.molmed.2008.06.002'] Humans do not produce Neu5Gc; however, trace amounts of the compound are commonly present in human urine, suggesting that Neu5Gc is obtained in the diet. Foods highest in Neu5Gc include red meat and milk. It is rarely present in fish or poultry, but eggs are rich in Neu5Ac... diet nutrition cancer inflammation
Read more[toc position='left'] Nicotinamide adenine dinucleotide (NAD+) is a cofactor (a molecule that assists enzymes in chemical reactions) that plays an essential role in multiple physiological processes, such as energy metabolism, DNA repair, and immune activation. It is necessary for the activity of sirtuins, a class of enzymes involved in longevity, and poly-ADP-ribose polymerases (PARPs), a family of DNA-repair enzymes. Cellular NAD+ production declines with age, however, and its depletion likely drives the onset and progression of multiple age-related conditions such as metabolic dysregulation ... metabolism mitochondria aging dna damage circadian rhythm nad+
Read more[toc position='left'] Bathing oneself in heat for the purposes of purification, cleansing, and healing is an ancient practice, dating back thousands of years and observed across many cultures. Variations of its use are seen today in the banyas of Russia, the sweat lodges of the American Indians, and, most famously, the saunas of Finland. Sauna use, sometimes referred to as "sauna bathing," is characterized by short-term passive exposure to extreme heat. This exposure elicits mild hyperthermia – an increase in the body's core temperature – that induces a thermoregulatory response involving neu... exercise inflammation sauna aging performance depression bisphenol a heat stress interesting alzheimer's
