Your Grip Strength is a Powerful Predictor

Grip strength is a simple and robust predictor of death risk.

A large, international study has revealed that for each 5 kilogram decrease in grip strength, over all mortality risk increased by 16%, cardiovascular mortality by 17%, and a 9% increase in stroke risk. The findings were consistent across nationalities and economic levels.

PositiveTip: Keep up the strength exercises. They could lower your risk of premature death.

The Myth of Resveratrol

Think again before you spend on resveratrol!

Resveratrol, a polyphenol antioxidant found in the skin of grapes, cocoa powder, dark chocolate, peanuts, and some berries has been hailed as the possible agent responsible for the benefits of red wine. However, research found it did not correlate with longevity or lower risk of cardiovascular disease or cancer. In fact, adjusted hazard ratios favored those with the lowest intakes, and there were no significant findings for all measured biomarkers.

PositiveTip: Eat a balanced diet, get plenty of physical activity, and live a positive lifestyle for the best health.

Cardiovascular Events and Cannabis Use

Dearth rate was 25% in adverse events associated with cannabis use.

A small, 5-year French study of cannabis-related reports of adverse events found an association with cardiovascular complications. The death rate was 25.6% and the average age was 34 years old. This is difficult to study because of the extreme variation in THC concentrations, the frequent use of other drugs, and the lack of strong control groups. More research is needed to determine if this association is causal.

PositiveTip: Though widely believed that cannabis use is harmless, evidence suggests it may be very risky.

Childhood Obesity May Damage Heart Early

Obese children with risk factors had a "vascular age" similar to a 45 year old healthy adult.

It it is recognized that childhood obesity increases the risk of cardiovascular disease later in life. However, increasing evidence strongly suggests it is also linked to cardiovascular damage during childhood. In reviewing the evidence, researchers found obesity during the growing years was associated with measurable alterations to the structure and function of the cardiovascular system.

PositiveTip: Prevention of obesity in children is vital for their immediate and future health.
