Study Finds Exercise Prolongs Lifespan

A study published Tuesday in the online edition of the American Heart Association’s journal Circulation suggests that frequent exercise can reduce the risk of death in men.

To examine the link between fitness and mortality, Veterans Affairs (VA) researchers gathered fitness data on 15,660 male VA patients undergoing treadmill testing for various medical reasons. The men, who had an average age of 60, where then assigned to one of four groups based on their level of fitness.

According to the results, mortality risk directly correlated with fitness level, with men in the highest fitness category being the least likely to die when compared to their less fit counterparts. For example, across the eight year study period, 44% of the men in the least fit group died, compared to 30% in the moderately fit group, 15% in the highly fit group, and 8% in the very highly fit group.

The Hype Over Human Growth Hormone

A lot of questions hit the MDA doorstep about HGH, Human Growth Hormone, and with good reason. It’s been touted in some circles as a bottled fountain of youth among other grandiose claims. Countless companies have jumped on that bandwagon, peddling worthless products with HGH labels.

We love to take on the propagandists and snake oil sales industries, and today will be no exception. Shall we begin?

The Basics of HGH
The natural HGH coursing through your body right now is, indeed, a perfectly remarkable anabolic hormone. It’s produced by the pituitary gland throughout life, but the levels gradually decline with age. The hormone is key for children’s growth and the health of the body’s organs. It stimulates the growth of muscle, bone and cartilage and enhances immune function. HGH is prescribed for children who are abnormally short in stature and for adults with diagnosed pituitary deficiency.

Study Finds Fitness Best Determinant of Future Cancer Risk

A study in the most recent edition of Obesity for the first time finds that fitness is more important than fatness in decreasing cancer mortality in men.

For the study, researchers from the not-for-profit Cooper Institute in Dallas tracked 38,410 men who completed a comprehensive baseline physical examination at Cooper Clinic in Dallas that included a maximal treadmill exercise test and measures of body mass index (BMI), percent body fat, and waist circumference. The men were then followed for an average of 17.2 years, during which 1,032 deaths from cancer occurred.

According to the researchers, there was a direct correlation between all measures of adiposity (body fat) and cancer mortality, with leaner men registering a significantly lower risk of cancer mortality than their fatter counterparts. In addition, the researchers also found a strong inverse relationship between cardio-respiratory fitness level and cancer mortality, with less fit men having a higher risk of cancer mortality than their fitter counterparts.

Healthy Tastes Great!

Smart Fuel: Sea Vegetables

Is it a plant? Is it an animal? Who cares when it tastes this delicious!

Classified as an algae (so neither plant nor animal!), the sea vegetable family counts ultra-healthy seaweed, sea lettuce, nori and kelp among its many relatives. Mimicking the mineral content of the ocean – which incidentally mimics the mineral content of human blood – sea vegetables are, pound for pound, the most nutrient dense food in existence.

On the minerals side, sea vegetables provide each of the 56 minerals required by the body for optimum physiological function. In addition, these minerals are made available in colloidal form, meaning that they are small enough to be easily absorbed by the body.
