Peel Me a Grape

1 Resveratrol’s Health Benefits Explained

Resveratrol, a compound in grapes has been touted as a panacea for everything from aging to obesity and now researchers at the UT Health Science Center, San Antonio, explain how the substance works. Resveratrol stimulates the production of adiponectin, a hormone derived from cells that manufacture and store fat. Working with cell and animal models, researchers found that both resveratrol and adiponectin display properties to fight obesity, insulin resistance and aging. “Results from these studies should be of interest to those who are obese, diabetic and growing older," says senior author Feng Liu, Ph.D. "The findings should also provide important information on the development of novel therapeutic drugs for the treatment of [certain] diseases."

Ten Years After

2 95 Percent of 9/11 Survivors Suffer PTSD Symptoms

Almost 10 years after the World Trade Center attack of 9/11, scientists at Columbia University, in conjunction with the NYC Department of Health and Mental Hygiene and the federal Agency for Toxic Substances Disease Registry, found that of the 3271 survivors of the Twin Towers, 95.6 % reported at least one symptom of post traumatic stress and 15 % screened positive for Post Traumatic Stress Disorder (PTSD) three years after the disaster. Other studies have focused on rescue workers, passersby and downtown NYC residents; this is the first study to focus on people who were inside the World Trade Center during the attack. PTSD, the third most common anxiety disorder in the US, involves feelings of helplessness, fear or horror.

Too Much of a Good Thing

3 Fluoride May Cause Spots on Teeth

Fluoride, added to drinking water since 1962, is causing spots or streaks on the teeth of some kids, reports CBS News. While the addition of fluoride to drinking water has dramatically reduced tooth decay by up to 90 percent, a new government report warns that too much fluoride is causing spots on teeth. Excessive fluoride has caused spots or tooth streaking on the teeth of two out of five adolescents, reports the CDC. Young teenagers appear to be affected more than other groups. Excessive fluoride may even cause pits in the teeth, yet other cases are so mild that only dental professionals notice. In response to the report, new recommended fluoride levels in water will be reduced to 0.7 milligrams per liter, instead of the usual range of 0.7 to 1.2 milligrams per liter.

Nothing to Do with Reform Law

4 Blue Shield Raises Health Insurance Rates

Blue Shield, one of the largest health insurers in California, plans to raise their premiums by as much as 59 percent, but they say it has "almost nothing to do with the federal health reform law," reports CNN. Blue Shield has also said that they believe that ultimately the new health reform will slow down costs. The large hike in rates will affect about 193,000 individual Blue Shield policy holders in California. Blue Shield blames the increase on several factors, including more expensive provider prices and healthier people dropping coverage in the bad economy. CNN reports that Blue Shield predicts they'll still "lose tens of millions of dollars" on their individual healthcare policies through 2011.

Inhaling the Road

5 Studded Tires Bad for Health

Microscopic road debris kicked up by studded tires is a hazard for drivers and people living near highways, say Swedish researchers. The research, published in the journal Chemical Research in Toxicology, revealed that airborne particles generated by studded tires could increase inflammation. Doug Brugge, of Tufts University School of Medicine in Boston, told MSNBC that the study is an important reminder that it's not just exhaust that we should be concerned about on the highway. He believes the particles created by studded tires can have "inflammatory and toxic effects." Since studded tires may damage roads, some states have banned them. Other states only allow the use of studded tires during winter months.

Off-Label Prescriptions Increase

6 Lack of Evidence for Uses of Antipsychotic Drugs

Many doctors write prescriptions for atypical antipsychotic medications without strong evidence that the drugs will help, finds a study by Stanford University School of Medicine and University of Chicago. The popular drugs may cause serious side effects, such as heart disease, weight gain and diabetes. Antipsychotic medications are often prescribed "off-label," for uses other than those approved by the FDA. One example is quetiapine (Seroquel), which is approved for schizophrenia and some aspects of bipolar disorder and depression, but is often prescribed for anxiety and dementia. Researchers examining information from surveyed doctors' visits found that off-label antipsychotic use increased from 4.4 million prescriptions in 1995 to 9 million in 2008.

Even Without Weight Loss

7 Mediterranean Diet Can Reduce Risk of Diabetes

Adhering to a Mediterranean-style diet has been shown in a new study to reduce the incidence of Type 2 diabetes by 52 percent in patients at high risk for cardiovascular disease. A Mediterranean diet is primarily plant-based, focusing on more vegetables and whole grains than meat, and includes virgin olive oil and nuts as the primary fat source. Researchers in Spain randomly assigned over 400 participants with a mean age of just over 67 years to either one of two traditional Mediterranean diets or a typical low-fat diet. After four years, the cumulative incidence of Type 2 diabetes was 10 to 11 percent for the Mediterranean diet followers versus almost 18 percent in the low-fat group, although weight changes among the participants were statistically insignificant.

Less Depression in Young Adults

8 Long Term Relationships Good for Mental Health

Despite jokes to the contrary, having long term lasting relationships is good for a person’s mental health. Research published in the British Journal of Psychiatry finds that men and women who are in relationships lasting longer than five years are less likely to be depressed, to consider or attempt suicide, or to be dependent on alcohol or drugs. The benefits exist regardless of marital status, family background and previous mental health problems. And the longer the relationship, the more the rates of depression and addiction declined. The study was conducted in New Zealand and focused on a cohort of 1,000 people between the ages of 25 to 30. Lead researcher Dr. Sheree Gibb says, “Our study suggests that partner relationships are protective for mental health.”

Cholesterol Also a Factor

9 High Fat Diet Increases Risk of Breast Cancer

Scientists have yet to find a single diet that is best for protection against breast cancer, but two components of a Western diet have been linked to the development of mammary tumors and make them grow faster and more aggressive. A study from the Kimmel Cancer Center has found that a diet high in fat (21 percent) and cholesterol predisposes mice to breast cancer tumors. They also found that feeding the mice high fat chow caused larger tumors that grew quickly and metastasized to other parts of the body, particularly the lung. Lead researcher Philippe G. Frank PhD notes that the incidence of breast cancer is five times higher in Western countries than in other developed countries, strongly suggesting an environmental influence.
