Multiple Benefits for Early Rising Active Seniors


A New Look at Saturated Fat


For decades, conventional wisdom has been that consuming saturated fat is a surefire way to sabotage cardiovascular health, clog arteries and advance the path to a heart attack. A new paper published in the European Journal of Preventive Cardiology


Older adults that consistently get up early and stay active throughout the day are happier and perform better on cognitive tests than those with irregular activity patterns, according to a new study led by researchers at the University of Pittsburgh. The researchers studied 1,800 adults 65 or older and divided them into four subgroups of activity patterns: earlier rising/robust, shorter activity duration/less modellable, shorter active periods/very weak and later activity offset/ very weak. Both groups with weak rhythms had twofold odds of clinically significant depression symptoms and cognitive performance deficits. As we age, disruption in activity patterns may be common. More research is needed into why earlier and robust patterns appear to be protective and whether modifying disrupted patterns improves health outcomes.


Two Cups of Tea May


Avert Early Death A few cups of black tea a day might help to avoid an early death, a study published in Annals of Internal Medicine suggests. Among nearly half a million adults


ranging from 40 to 69 years old, those that consumed two or more cups of tea a day saw a modest, but lower risk for all causes of mortality over a median follow-up of more than 11 years. Participants of the large cohort study, called UK Biobank, self-reported tea intake from 2006 to 2010, while researchers noted mortality from all causes, including cardiovascular disease, ischemic heart disease, stroke and respiratory disease. The researchers concluded that drinking more than two cups of tea per day can be part of a healthy diet.

looked at the relationship between consuming saturated fat and the development of cardiovascular disease by conducting a review of articles published between 2010 and 2021 on the subject. The researchers found there is no scientific ground to demonize saturated fat as a cause of cardiovascular disease, and saturated fat naturally occurring in nutrient-dense foods can be safely included in the diet.


Glycine and NAC May


Delay Aging A new clinical trial by researchers at Baylor College of Medicine, in Houston, found that a


combination of N-acetyl cysteine and


glycine (GlyNAC) boosted glutathione—often referred to as the body’s master antioxidant—and improved or reversed many signs of aging. Twenty-four older adults and 12 young adults were studied. The older group was randomized to receive either GlyNAC or a placebo for 16 weeks, and the younger adults received GlyNAC for two weeks. Participants were studied before, after two weeks and after 16 weeks of supplementation to assess glutathione concentrations, oxidative stress, mitochondrial fatty-acid oxidation, molecular regulators of energy metabolism, inflammation, endothelial function, insulin resistance, aging hallmarks, gait speed, muscle strength, walking (via a six-minute test), body composition and blood pressure. Supplementing with GlyNAC in the older adults was found to improve or correct these markers. Researchers concluded that this nutritional supplementation was a safe, well-tolerated and effective method for improving or reversing multiple, age-associated abnormalities to promote health in aging adults.
