Regular Exercise Reduces a Large Number of Health Risks

Regular exercise can reduce the risk and symptoms of more than 20 physical and mental health conditions, and can also slow down how quickly your body ages.

A review of research, which summarized the findings of 40 papers published between 2006 and 2010, found that exercise affects conditions including cancer, heart disease, dementia, stroke, type 2 diabetes, depression, obesity and high blood pressure.

Science Daily reports:
“… [A]part from not smoking, being physically active is the most powerful lifestyle choice any individual can make to improve their health.”

A separate study also found that women who exercise for 150 minutes a week or more could be reducing their risk of endometrial cancer, whether or not they are overweight.

Researchers examined data collected from a case-control study that included almost 700 women with endometrial cancer and compared them to a similar number of age-matched control women. Those who exercised for 150 minutes a week or more had a 34 percent reduced risk of endometrial cancer.

Newswise reports:
“This association was more pronounced among active women with a body mass index (BMI) less than 25, or underweight women, where the reduction in risk was 73 percent compared with inactive women with a BMI more than 25, or what is commonly considered overweight.

Although BMI showed a strong association with endometrial cancer, even women who were overweight, but still active, had a 52 percent lower risk.”

Coke’s New ‘Healthy Front’ May Be Just a Big Bluff

Diet Coke and the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health have joined forces to raise awareness about women’s risk of heart disease. Diet Coke’s Red Dress Program will take center stage at high-profile events.

……..

The Center for Science in the Public Interest points out that Coca-Cola, whose products are not exactly heart healthy, is a strange partner for the NHLBI.

Are such partnerships a benign win-win? History suggests otherwise.

In 1984, Kellogg cooked up a partnership with the National Cancer Institute to put health claims for fiber on the boxes of All-Bran cereals. In doing so, Kellogg (and NCI) went around the FDA and undermined that agency’s control over health claims on food packages — leading to problems that the agency is still struggling to fix.

Grape Seeds May Prevent Worst Health Disasters

For years, scientists have given two thumbs up to grape seed extract as a powerful disease fighter. Now, findings by the American Association for Cancer Research show it may be powerful enough to blast away leukemia cells!

As its name implies, grape seed extract is pressed from the seeds of grapes. Laboratory studies have shown that grape seeds contain helpful antioxidants that prevent cell damage caused by free radicals.

Grape seed extract has also been shown to strengthen the heart and blood vessels… reduce high blood pressure… improve symptoms of diabetes… lower high cholesterol… and may even help treat and prevent cancer!

According to a statement from the association, a study revealed that after laboratory leukemia cells were exposed to grape seed extract, 76 percent of the cancer-laden cells were completely eliminated! Even more amazing was the fact that other cells were not harmed.

“What everyone seeks is an agent that has an effect on cancer cells but leaves normal cells alone, and this shows that grape seed extract fits into this category,” said Xianglin Shi, one of the researchers and a professor in the Graduate Center for Toxicology at the University of Kentucky.

“These results could have implications for the incorporation of agents such as grape seed extract into prevention or treatment of hematological malignancies and possibly other cancers,” Shi said.

However, the results of the study do not suggest that people should go overboard in eating grapes in hopes of staving off cancer. “This is very promising research, but it is too early to say this is chemo-protective,” Shi added.

Green Tea May Help Reduce Risk of Certain Cancers

Researchers in Japan have said drinking green tea may be an important health resource to reduce the risk of developing certain types of cancer.

The study appearing in the American Journal of Epidemiology suggests drinking five or more cups of the antioxidant-rich beverage can reduce the risk of developing blood cancer by 42 percent. The same amount of green tea was also associated with a 48 percent lower risk of lymph system cancer, according to Reuters.

Researchers followed 19,749 men and 22,012 women with no previous history of cancer over a period of nine years for the study.

WebMD notes that previous research has linked the tea to fighting heart disease, lowering cholesterol and preventing diabetes and dementia.

“Taken altogether, the evidence certainly suggests that incorporating at least a few cups of green tea every day will positively affect your health. It’s not going to cure anything and it shouldn’t be consumed as a drug, but it can complement the rest of the diet,” Tufts University scientist Dr. Diane McKay tells WebMD.

Researchers involved with this study say further work is needed to confirm the health benefits of drinking green tea, and to determine whether daily consumption might prevent certain cancers.

Algae May Harbour SARS Cure

Products from Amazon.com

A protein from algae might help in treating Severe Acute Respiratory Syndrome (SARS) infections, suggests a new study.

click & see the pictures
Researchers from University of Iowa have found that mice treated with the protein, Griffithsin (GRFT), had a 100 percent survival rate after exposure to the SARS coronavirus (SARS-CoV), as compared to a 30 percent survival for untreated mice.

GRFT is believed to exert its anti-viral effects by altering the shape of the sugar molecules that line the virus‘ envelope, allowing it to attach to and invade human cells, where it takes over the cells’ reproductive machinery to replicate itself.

Without that crucial ability, the virus is unable to cause disease.

“While preliminary, these results are very exciting and indicate a possible therapeutic approach to future SARS or other coronaviral outbreaks,” said Christine Wohlford-Lenane, senior research assistant at the department of pediatrics University of Iowa and the lead author of the study.

GRFT not only stop the virus from replicating, but also prevented secondary outcomes, such as weight loss, that are associated with infection.

“We are planning future studies to investigate prophylaxis, versus treatment interventions with GRFT, in the SARS mouse model in collaboration with Barry O’Keefe at the National Cancer Institute,” she said.

“In addition, we want to learn whether mice protected from SARS by GRFT develop protective immunity against future infection,” she added.

The research was presented at the American Thoracic Society‘s 105th International Conference in San Diego.
