High Levels of Exercise Linked to Nine Years of Less Aging at the Cellular Level

Despite their best efforts, no scientist has ever come close to stopping humans from aging. Even anti-aging creams can't stop Old Father Time.

But new research reveals you may be able to slow one type of aging -- the kind that happens inside your cells. As long as you're willing to sweat.

"Just because you're 40, doesn't mean you're 40 years old biologically," Tucker said. "We all know people that seem younger than their actual age. The more physically active we are the less biological aging takes place in our bodies."

The study, finds that people who have consistently high levels of physical activity have significantly longer telomeres than those who have sedentary lifestyles, as well as those who are moderately active. According to Science daily.

Widespread vitamin D deficiency likely due to sunscreen use, increase of chronic diseases, review finds

Results from a clinical review find nearly 1 billion people worldwide may have deficient or insufficient levels of vitamin D due to chronic disease and inadequate sun exposure related to sunscreen use. According to Science daily

The study also found that 95 percent of adults may have vitamin D deficiency or insufficiency. Vitamin D variations among races are attributed to differences in skin pigmentation.

"People are spending less time outside and, when they do go out, they're typically wearing sunscreen, which essentially nullifies the body's ability to produce vitamin D," said Kim Pfotenhauer, DO, assistant professor and a researcher on this study. "While we want people to protect themselves against skin cancer, there are healthy, moderate levels of unprotected sun exposure that can be very helpful in boosting vitamin D."

A brisk walk instead of sitting down: Just ten minutes a day makes a difference

It is not the amount of time spent sitting still that matters. Instead it is the extent of physical activity that is essential in reducing the risk of elderly women developing cardiovascular disease, as shown in a new study. According to Science daily

"We have studied women over 65 as they are among the least active groups of the population, at the same time as they run a high risk of developing cardiovascular disease," says Fawzi Kadi, Professor.

A sedentary lifestyle is associated with health risks such as diabetes and cardiovascular disease. But the study shows that it is the daily amount of physical activity that is crucial to a person's health.

"The study shows how important it is to encourage more physical activity. We are not talking slow everyday pace, but at least one brisk walk or other physical activity requiring some exertion," says Andreas Nilsson, researcher.

Non-O blood group 'linked to higher heart attack risk

People with a non-O blood group have a slightly increased risk of heart attack and stroke, research suggests. According to BBC.

Scientists say it could be because higher levels of a blood-clotting protein are present in people with A, B and AB blood.

The findings could help doctors better understand who is at risk of developing heart disease, the researchers said.

The research, analysed studies involving 1.3m people.

Eating cheese could prevent you from getting liver cancer

Many people avoid regularly eating cheese over fears of what it may do to their waistlines. According to Daily mail

Yet, eating aged cheeses, including cheddar, brie and parmesan, could boost your liver health. 

These cheeses contain a compound, known as spermidine that stops damaged liver cells from replicating.

This may prevent liver fibrosis - the accumulation of scar tissue that occurs in most disease of the organ, and hepatocellular carcinoma (HCC), which is the most common form of liver cancer.
