“Here’s an interesting report that didn't make it into this issue of the Digest. Obesity and aging increase a person's risk of many diseases, including cardiovascular diseases and type 2 diabetes. This review presents the hypothesis that obesity accelerates the process of cardiac aging, exacerbating clinical outcomes of older adults with obesity.”

“Age acceleration can result from intrinsic factors, such as normal metabolism and genetics, or extrinsic factors, such as diet, smoking, and exercise. Learn how epigenetic changes influence biological aging in our overview article. Read study abstract.”

“Brain aging begins long before memory problems appear, but researchers still debate when lifestyle changes can measurably influence brain structure. A randomized clinical trial tested whether an aerobic exercise program that matches common activity recommendations can alter an MRI-derived estimate of brain aging in early and midlife adults.”

“After accounting for age, predicted testosterone fell from about 500 to 300 ng/dL as waist circumference increased from 80 to 120 cm, from about 900 to 250 ng/dL as body fat rose from 5% to 45%, and from about 700 to 230 ng/dL as visceral fat area increased from below 50 to above 300 cm2.”

“A new study suggests that transplanting fecal microbiota from aged mice donors impairs cognitive function in younger mice recipients. Aging is the collective physiological, functional, and mental changes that accrue in a biological organism over time.”

“Researchers used magnetic resonance imaging to determine the volume of the participants' gluteus maximus and gluteus medius muscles, which are situated in and around the buttocks, as well as the percentage of fat infiltration within those muscles.”

“While brain aging is an inevitable part of growing older, lifestyle factors, particularly diet, can influence the rate at which this aging occurs. A recent study found that older adults with diets rich in omega-3 fatty acids, antioxidants, and vitamins demonstrate slower brain aging and better performance on cognitive tests.”

“Glutathione levels decrease with aging. Findings from a new study suggest that supplemental glycine and cysteine restore glutathione levels and correct several markers of aging. Glycine and cysteine (commonly provided as N-acetylcysteine, or NAC) are amino acids.”

“They also found that daily smoking played a role in the relationship between the genetic risk score for smoking initiation and the total gray matter volume. These findings suggest that smoking cigarettes reduces drives brain volume losses, effectively aging the brain prematurely.”

“Having sufficient muscle mass markedly reduces a person's risk of dying prematurely, and actively challenging those muscles, through regular physical activity and exercise, may extend a person's life by several years. Learn more in this clip featuring Dr. Stuart Phillips.”
