“BDNF and type 2 diabetes Type 2 diabetes is a metabolic disorder characterized by high blood glucose levels due to acquired resistance to insulin, a hormone produced by the pancreas. BDNF administration reduces blood glucose levels in mouse models of type 2 diabetes.”

“Introduction Light does much more than help us see. It tells the brain what time it is. That signal coordinates sleep and wakefulness, hormone release, metabolism, mood, and hundreds of other processes that follow a roughly 24-hour rhythm.”

“A meta-analysis of 51 studies found lower levels of arachidonic acid (an omega-6 fatty acid) and DHA as a percentage of plasma lipid in men compared to women, suggesting that gender-specific differences occur in long-chain fatty acid metabolism, possibly modulated by sex hormones.”

“The same shift in hormones may occur in humans deprived of sleep. Thirteen young adults (average age, 21 years) completed two testing days in random order in which they experienced one night of sleep deprivation and one night of normal sleep.”

“Ghrelin, a hormone produced in the gut that signals hunger, acts on cells in the hypothalamus to stimulate appetite, increase food intake, and promote growth. It is often referred to as the "hunger hormone."”

“00:08:06 - How the suppression of the IGF-1 pathway, typically a hallmark of prolonged fasting and caloric restriction studies and potentially needed for some of the benefits, may fail to be achieved in human caloric restricters that eat too much protein. 00:09:34 - How certain macronutrients influence the insulin/IGF-1/growth hormone axis interact to modulate aging in many cell types.”

“Vitamin D, like other steroid hormones, can enter a cell's nucleus and regulate numerous genes. Vitamin D serves as a major regulator of immune function and may play a particularly important role in preventing respiratory tract infections.”

“Multiple age-related inputs can keep innate immune pathways active, including the senescence-associated secretory phenotype, mitochondrial damage and oxidative stress, debris released by injured cells, visceral adipose tissue inflammation, chronic infections, increased intestinal permeability, and dysbiosis.”

“Obesity has long been associated with a higher risk of developing Alzheimer’s disease, but scientists don't fully understand what drives this link. However, some research indicates that leptin, a hormone that regulates appetite and body weight, may be vital in protecting brain health.”

“Many food-contact chemicals include bisphenol A, phthalates, and other toxic substances that promote cancer, impair fertility, and disrupt hormone signaling. Although many of these compounds accumulate in the body over time, some are preferentially excreted in sweat.”
