tness is beneficial to cognitive function (HartmanStein, et al., 2020) Nutrition or A Waist is a Terrible Thing to Mind • Caloric restriction appears to delay normal agerelated degeneration of almost all physiological systems. (NIA, 2020). In animal studies it was found that calorie restricted diets are more important to an extended life span than maintaining a healthy weight and exercising (Mayo Clinic, 2020) • Exactly why this happens is not known but it is hypothesized that cutting down on calories slows metabolism. Since free radicals are a byproduct of metabolism, fewer free radicals are generated and oxidative damage to cells is lessened • Calorically restricted animals also have somewhat lower body temperatures which may lower geic damage to cells • There is also less free glucose circulating in the systems of calorically restricted animals which may reduce the potential for protein crosslinking, a biochemical process implicated in cellular aging • As we age, our basal metabolic rate decreases so that we need fewer calories each day to maintain normal weight. (Madsden, et al., 2020。 Mayo Clinic, 2020). As metabolism slows, calories which were hitherto used to fuel your body‟s energy needs are now stored as fat (Medline Plus, 2020) Limit Your Vices • Cigarette smoking is one of the single most damaging factors to the body overall. Cigarette smoking causes 90% of lung cancers and people who stop no matter how long they have been smoking immediately lower their risk of getting lung cancer • Cigarette smoking has been shown to be a factor in the increased risk for cartilage loss and knee pain in men with knee osteoarthritis (Amin, et al., 2020) • Cigarette smoking also results in lowered immunity to infections and it suppresses normal healing processes • It is remended that alcoholic drinks be limited to no more than 2 drinks per day for men and 1 drink per day for women. Excessive alcohol intake causes many adverse effects if it is taken in large amounts over time. Among other things, it can increase blood pressure, decrease immunity and cause memory loss • Research has shown a direct link between sleep deprivation and memory loss. Sleep needs change little throughout adulthood. At least 6 hours of sleep each night are required for memory to perform at its peak and regular sleep habits also make you less fetful • Depression。
