Aging, Activity and Telomeres

Researchers analyzed data from nearly 1500 women, ages from 64 to 95. Results reported that elderly women with less than 40 minutes of moderate-to-vigorous physical activity per day, and who remain sedentary for more than 10 hours a day, have shorter telomeres – tiny caps on the ends of chromosomes of DNA strands.

Telomeres protect chromosomes from deterioration and progressively shorten with age. As a cell ages, its telomeres naturally shorter and fray, but unhealthy lifestyles such as obesity and smoking may accelerate this process. Shortened telomeres are associated with heart disease, diabetes and major cancers. This study was funded, in part, by the National Institute on Aging and conducted at the University of California San Diego School of Medicine.

Tea May Protect Against Coronary Artery Disease

A review of randomized trials published in the journal Clinical Nutrition ESPEN, concluded that regular intake of green tea may help reduce the risk of cardiovascular disease.

Regular tea consumption was associated with lower blood pressure and enhanced bioavailability of nitric oxide, which indicate a beneficial effect for tea on endothelial function. In some studies, tea was associated lower markers of oxidative stress and inflammation (C-reactive protein and oxidized low -density lipoprotein (LDL).

NOTE: ENDOTHELIAL= the tissue which forms a single layer of cells lining various organs and cavities of the body, especially the blood vessels, heart, and lymphatic vessels.

More Good News for Garlic Lover

Garlic supplementation Improves metabolic syndrome. Phytother Res. 2021, May 11.

I am not a promoter of supplements except in situations when you don’t want to smell like a raw garlic bulb every day.

Editors Note: Metabolic syndrome is becoming a marker for good health especially in the older population; however its presence can occur even in younger people. It is diagnosed as having three of the following disorders: high triglycerides, high blood pressure, elevated blood sugar and low levels of HDL cholesterol. These disorders collectively are thought to contribute to a higher risk of developing diabetes and/or heart disease

A randomized clinical trial included 90 men and women with metabolic syndrome were supplemented with tablets containing 1600 mg of garlic powder daily for three months, or a placebo.

In the garlic group, results were as follows:

All parameters were reduced along with appetite, fatty liver index,and waist circumference. Additionally,  beneficial HDL cholesterol was significantly higher than at the beginning of the study compared to the placebo group. 

“Then, there is cancer. Compounds in garlic have been shown in many laboratory studies to be chemoprotecive. Epidemiological studies shows a decreased risk in stomach and colon cancer in areas where consumption of garlic is high. An article In the Journal of Nutrition stated that “evidence continues to point to the anticancer properties of fresh garlic extracts, aged garlic, garlic oil.”
