Creating Powerful Health — Take Control of Your Health

Cancer, Mental Agility and Vitamin D

Researchers studying the preventive effects of vitamin D on cancer have proposed a new model of cancer development that hinges on a loss of cancer cells’ ability to stick together. The model, dubbed DINOMIT, differs from the older model of cancer development, which suggests genetic mutations as the earliest driving forces behind cancer. “The first event in cancer is loss of communication among cells due to, among other things, low vitamin D and calcium levels,” said epidemiologist Cedric Garland. “This loss may play a key role in cancer by disrupting the communication between cells that is essential to healthy cell [...]

Can Exercise Cut Your Cancer Risk?

New research makes a strong case for exercise as a way to help prevent cancer both for men and women. Let’s consider the results of two related studies. Men – Those with stronger muscles from regular weight training are up to 40 percent less likely to die from cancer, according to new research. These findings suggest that muscular strength is as important as staying slim and eating healthy when it comes to protecting your body against deadly tumors. A team of experts tracked the lifestyles of over 8,500 men for more than two decades. Each volunteer had regular medical check [...]

Plastic Water Bottles Pulled From Shelves

Worries about the hormone-mimicking chemical bisphenol A (BPA) used in Nalgene plastic water containers have led a major Canadian retailer to remove Nalgene, along with other polycarbonate plastic containers, from store shelves in early December. There is little dispute that the chemical can disrupt the hormonal system, but scientists disagree on whether the low doses found in food and beverage containers can cause harm. The FDA and the plastics industry have argued that BPA-based products do not pose a health risk. However, an expert panel of researchers recently reported that the potential for BPA to affect human health is a [...]

The FDA and Food Safety

After the first reports of a salmonella outbreak this spring, it took a full 89 days before jalapeño and serrano peppers came under suspicion as the culprit. During that period, more than 1,440 victims were hospitalized. Even as bacterial outbreaks have become more high-profile, and the financial fallout from recalls more severe, the government has been handing off many food-safety responsibilities to private industry. Food safety today is a business. For most Americans, the FDA is still the public face of food safety. But in reality, oversight of farms and food plants has gradually changed hands. There is now a [...]

Can Thinking Make You Fatter?

A research team has demonstrated that intellectual work induces a substantial increase in appetite and calorie intake. This discovery could help to explain, in part, the current obesity epidemic. The team measured the spontaneous food intake of 14 students after each of three tasks: relaxing in a sitting position, reading and summarizing a text, and completing a series of memory, attention, and vigilance tests on the computer. Each session of intellectual work required only three calories more than the rest period. However, despite the low energy cost of mental work, the students spontaneously consumed 203 more calories after summarizing a [...]

Can You be Fat and Fit?

Is a person’s weight really a reliable indicator of overall health? Some medical research is showing that it isn’t. Last week a report in The Archives of Internal Medicine compared weight and cardiovascular risk factors among a representative sample of more than 5,400 adults. Half of the overweight people and one-third of obese people in the study were “metabolically healthy.” That means that many overweight and obese adults may have healthy levels of “good” cholesterol, blood pressure, and blood glucose. At the same time, about one out of four slim people in the study actually had at least two cardiovascular [...]

How to Do Breast Checks

Is there a right way to check your breasts for early signs of cancer? Many women remain confused as experts now say there is no evidence that rigorous monthly “self-examination” — widely recommended in the United States — reduces breast cancer deaths. Plus, it can lead to unnecessary biopsies. Two large studies looking at a total of more than 388,000 women found that death rates from breast cancer were the same among women who rigorously self-examined as those who did not, while there were almost twice the number of biopsy operations in the self-examination group. According to some experts, the [...]

Vitamin D Deficiency, a Risk Factor for Cancer?

In this video, Dr. Mercola interviews Dr. William Grant, Ph.D., internationally recognized research scientist and vitamin D expert, reveals the important role vitamin D plays in your health. Dr. Grant, whose background is in atmospheric sciences, has applied the ecologic approach to the study of dietary and environmental links to chronic disease. He has worked at the level of senior research scientist at such notable institutions as SRI International, the Jet Propulsion Laboratory, and the NASA Langley Research Center. More recently, Dr. Grant has uncovered exciting potential for the use of vitamin D in the prevention and treatment of a [...]

A Simple Way to Get Smarter

The latest research suggests that while you are asleep, your brain is busily processing the day’s information. It combs through recently formed memories, stabilizing, copying, filing, and making them more useful for the next day. A night of sleep can make memories resistant to interference from other information and allow you to recall them more effectively. It also lets your brain sift through newly formed memories, possibly even identifying what is worth keeping and what to let go of. During sleep, your mind analyzes collections of memories, helping you discover hidden relations between seemingly random pieces of information, and helps [...]
