How vitamin D helps prevent lung cancer

by: Aurora Geib

Increasing vitamin D may now be a matter of life or death, as recent studies have shown that it may play a vital role in the fight against lung cancer. To date, lung cancer is one of the three most common cancers that kill men and women in developed countries with a statistic of one million deaths every year.

Researchers from the University of California at San Diego discovered a correlative relationship between higher rates of lung cancer and less exposure to the sun.

Cancer and vitamin D

The study compared data from national and international databases and compared the lung cancer rates in 111 countries. It found a correlation with smoking, lung cancer and significant lower UVB exposure. Although the current study focused only on lung cancer, research conducted on other cancers have pointed to the fact that most cancer cases are seen in subjects living far from the equator, suggesting that lower levels of vitamin D also account for a high risk of colon and other cancers.

Hormone Therapy for Prostate Cancer Raises Heart Risks

(HealthDay News) -- Hormone therapy to treat advanced prostate cancer can increase the risk of heart disease, but some types of hormone therapy appear to be safer than others, new research has found.

The study included 30,642 Swedish men with either locally advanced prostate cancer or prostate cancer that had spread (metastatic cancer), who had received hormone therapy as primary treatment for their cancer.

The study findings were scheduled to be presented Tuesday at the European Cancer Organization meeting in Berlin.

In a news release from the European Cancer Organization, the researchers described the types of hormone therapy used: removal of the testicles to eliminate the main source of testosterone production; injections of gonadotropin-releasing hormone agonists to reduce testosterone production by the testicles; and anti-androgen pills that block testosterone from attaching to prostate cells. Most of the patients received one treatment, but 38 percent were given two types of drugs, the study authors noted. Read more…

Want to Lose Weight? Just Eat Less, Diet Study Suggests

(HealthDay News) -- If you want to lose weight, it doesn't seem to matter what type of diet plan you choose. What really matters is that you just eat less.
A study in the Feb. 26 issue of the New England Journal of Medicine compared a variety of diet plans -- which emphasized varying degrees of fat, protein and carbohydrates -- and found that any eating plan that causes you to consume fewer calories will help you lose weight.
"This study has a very practical, useful message," said study author Dr. Frank Sacks, a professor of cardiovascular disease prevention at the Harvard School of Public Health. "It doesn't really matter much the specific type of diet -- see what suits you best. The focus should be on reducing calories. That's what really counts."
Intense debates have raged over what type of diet plan is best. Study results on low-fat diets and high-protein diets have been mixed, with none providing conclusive evidence, according to background information in Sacks' study. Read more…

The Department of Homeland Security plans to build a high-risk virus

The Department of Homeland Security plans to build a high-risk virus research center in the heart of America
by: J. D. Heyes

The Department of Homeland Security (DHS) is set to begin construction on a new high-risk bio-weapons research facility on the campus of Kansas State University in Manhattan, though critics say the decision is fraught with risk because of the potential for damage from nearby earthquake fault lines.

In a statement on its Web site, DHS said it needs the new facility to replace an aging one located at Greenport, N.Y. That facility, known as the Plum Island Animal Disease Center, has been in operation since 1954 and is nearing the end of its useful life.

According to the department, $54 million has been approved for the construction of the proposed National Bio and Agro-Defense Facility. The new facility will feature research on biolevel 3 and 4 viruses - some without any known cures - and other potentially dangerous materials, though department officials have downplayed any potential threats.

Vitamin D May Be Tied to Heart Disease Via Genes

(HealthDay News) -- New research points to the possibility of a genetic link between vitamin D and heart disease.

People with high blood pressure who had a gene variant that reduces vitamin D activation in the body were found to be twice as likely as those without the variant to have congestive heart failure, the study found.

The finding may lead to a way to identify people at increased risk for heart disease, according to Robert U. Simpson, an assistant professor of pharmacology at the University of Michigan Medical School and his research colleagues.

They analyzed the genetic profiles of 617 people. One-third had hypertension, one-third had hypertension and congestive heart failure, and the remaining third served as healthy controls.

The researchers found that a variant in the CYP27B1 gene was associated with congestive heart failure in people with hypertension. The study is in the November issue of Pharmacogenomics. Read more…

Why more thyroid cancer? Fluoridated water, x-rays, and radiation are all to blame

by: Ethan A. Huff

According to a recent report in USA Today, cases of thyroid cancer have risen 6.5 percent over the past several years, and many medical experts are at a loss for explaining why this is occurring. But mainstream science is ignoring all the most obvious factors that contribute to the disease -- fluoride chemicals added to drinking water; excessive medical x-rays; and radiation from cells phones, computers, naked body scanners, and nuclear disasters like Fukushima.

Perhaps one of the most misunderstood organs in the body, the thyroid gland purifies the blood and detoxifies the body by taking up iodine nutrients and using them to cleanse the blood, which in turn lowers the amount of toxins run through the liver. But the thyroid gland's iodine receptors also take up harmful radiation like the kind emitted from modern communication devices, x-rays, and nuclear accidents, as well as toxic fluoride chemicals added to drinking water supplies across the country.

Simple strategies buffer blood sugar

by: Dr. David Jockers

Sweet foods and starches are not genetically congruent to eat on a regular basis. Our ancestors looked at these as rare delicacies. Most people in our society today are raised on a steady diet of sugars, grains and other starches. Here are the best strategies to lower the blood sugar/insulin response when consuming carbohydrate rich foods.

Foods are measured for their effect on blood sugar through the Glycemic Index (GI). The GI ranges from 0-100. Foods that have a GI index under 55 are considered low GI. A range of 56-69 is considered medium GI while 70+ is considered high. It is recommended to eat foods that are low GI and to utilize different strategies to lower and/or buffer these GI responses in your body.

Another way of ranking the blood sugar response of different foods is through the Glycemic Load (GL). The GL measures how long the food will release sugar into the system. Many foods may be high GI but low GL. An example of this would be fruit such as watermelon. Other foods are low GI but high GL such as oatmeal, which releases sugar into the system for an extended period of time. Readmore…
