More Is Better

1 Exercise Reduces Heart Disease Risk

Exercise reduces heart disease risk and the greater the amount of time spent on physical activity, the greater the benefits finds a review published in the journal of the Am. Heart Assn. US guidelines recommend 2 1/2 hours of exercise per week and found that those who comply had a 14% lower risk of heart disease than those who don’t exercise. But even people who exercise less than that have a lower risk of heart disease than those who don’t exercise at all. "The overall findings of the study corroborate federal guidelines -- even a little bit of exercise is good, but more is better -- 150 minutes of exercise per week is beneficial, 300 minutes per week will give even more benefits," said Jacob Sattelmair, ScD, Harvard School of Public Health.

Fewer Baby Colds

2 Fish Oil During Pregnancy May Protect Infants

Taking fish oil supplements while pregnant may protect babies against colds during their first months, suggest researchers from Emory University. Preliminary study findings show that infants whose mothers took an omega-3 fatty acid found in fish oil (DHA or docosahexaenoic acid) were sick less often and for a shorter time than infants whose mothers didn't take DHA. Researchers followed 851 Mexican women starting in their second trimester until infants were six months old. Half were given 400 milligrams a day of DHA beginning in the second trimester. The other half took placebos. Babies whose moms were given DHA had shorter periods of respiratory symptoms when they were sick, but more research is needed before doctors will call for DHA as an essential part of the pregnancy diet.

Better to Eat Right, Exercise

3 Colon Cleansing Has No Benefit, Serious Risks

A review of the available literature conducted by Georgetown University doctors has concluded that there is no scientific evidence to back the claim that colonic irrigation or colonic hydrotherapy offers any benefits such as enhancing well-being. However, the practice of flushing the colon with water and chemicals does present some serious risks, such as electrolyte imbalance and renal failure. Some preparations are also linked to aplastic anemia and liver toxicity. Other side effects can include cramping, bloating, nausea, and vomiting. The review, published in The Journal of Family Practice, included 20 studies published in the last decade. Lead author Ranit Mishori MD also notes that “colon hygienists” have no significant medical training.

May Lead to Better Screening

4 Dyslexics Have Difficulty Recognizing Voices

A new study shows that people with dyslexia may have difficulty with voice recognition. Researchers had the English-speaking participants, half of whom had dyslexia, listen to and try to correctly match voices to a clown, mechanic and soccer player. Those with dyslexia were able to match the voice with the character only 50 percent of the time compared to 70 percent in those without the disorder, regardless of whether the character spoke English or Chinese. Dyslexic’s brains have a problem in phonological processing which impairs the ability to distinguish or manipulate sounds that are associated with written words and speech. This study has led researchers to wonder if a test can be designed to screen kindergartners for the disorder.
