Damage in Minutes, Not Years

1 Cigarette Smoke Causes Damage Within Minutes

Cigarette smoke starts to cause genetic damage within minutes of inhalation into the lungs, say researchers reporting in a journal published by the American Chemical Society. The research is the first human study to detail how particular substances contained in tobacco bring about DNA damage linked with cancer. Writing in Chemical Research in Toxicology, the researchers warn that the reported results "should serve as a stark warning to those who are considering starting to smoke cigarettes." Stephen S. Hecht, Ph.D., says that the study is the first to investigate human metabolism of a polycyclic aromatic hydrocarbon (PAH) from inhaling cigarette smoke with no interference from other sources like air pollution or diet.

Walk Away Diabetes Risk

2 Diabetes Prevention: Take More Steps

Adding more steps to your day can help you ward off diabetes, as well as obesity, suggest researchers in Australia. Published in BMJ, the research is the first to estimate the impact of long-term changes in daily step count on insulin sensitivity. Nearly 600 middle-aged adults using pedometers took part in the five-year study. Researchers found that a higher daily step count during the study period was associated with a smaller body mass index and waist to hip ratio, as well as better insulin sensitivity. The study authors write that the findings "provide further support to promote higher physical activity levels among middle aged adults."

Still Divided, but Less Intense

3 Opposition to Health Care Reform Weakens

An Associated Press-GfK poll has found that opposition to the new health care reform is weakening. CBS News reports that while the nation is still divided over the health care reform law, the opposition is diminishing in strength and intensity. The new poll reveals that strong opposition to the health care law is at 30 percent. Forty percent of those polled support the law, but 41 percent are opposed. In November, opposition stood at 47 percent, while support was 38 percent. Republican support for repealing the health care law has declined from 61 percent in November to 49 percent currently.

Pretty Face = Higher IQ

4 Beautiful People Are Smarter

Pretty people have greater intelligence than ugly folks, particularly if they're men, reports Psychology Today. The evidence for the association between beauty and brains is much stronger than previously thought. Researchers drew on data from the National Child Development Study, which included all babies born in Great Britain during a week in March of 1958. Researchers followed the participants for more than half a century. According to the research, women rated as attractive had a mean IQ of 103.64, while unattractive women had a mean IQ of 92.25. Attractive men had a mean IQ of 105.00, while unattractive men had a mean IQ of 91.39.

No Behavior Change

5 Menu Nutrition Labels May Not Help

"I think it would be really helpful if they put the calories for foods on billboards in big, readable lettering. ie - BIG MAC - 1,000 calories (half your daily allowance). Starbx frappamadness - 800 calories - BIG LETTERS."
- Albert in the comments

Adding nutrition labels to menus may not help combat obesity, suggest researchers who studied one fast-food chain restaurant with menu nutrition labels. The one-year study showed that the menu nutrition labels didn't change consumer behavior, reports MSNBC. The study, published in the American Journal for Preventive Medicine, was conducted in the state of Washington. Additional study is needed to find out if the menu nutrition labels would have a bigger impact if used on a large scale. The findings suggest that health-conscious consumers may already know the calorie content of their food. Within a few months, restaurants with 20 locations or more must add nutrition labels to menus.

O for Heart Attack Protection

6 Gene for Type O Blood May Reduce Heart Attack Risk

Researchers have discovered the gene that leads to developing type O blood appears to reduce the risk of having a heart attack even in the presence of cardiovascular disease. About 13,000 people with heart disease were compared to 7,400 healthy people. They also looked at 5,800 who had a heart attack and 3,600 with the condition who did not and discovered a gene called ADAMTS7 linked to an increased risk of coronary artery disease and also found that the gene that produces type O blood reduces the risk of a heart attack. This does not mean people with type O should not prevent heart disease, but researchers believe that these results will provide them with a better understanding of heart disease and lead to treatments by altering the function of the gene and blood typing.
