      The Risks of Being Left Handed

      December 11, 2011 /

      Left handedness has been a fascination of scientists for centuries.

      Curiosity ranged from fear to questions about how the brain works and what is different about left handed brains.

      New research explores what might cause left handedness and what, if any health risks may accompany this trait and whether or not the cause is in the genes or in the environment.

      Handedness, as the dominance of one hand over the other is called, provides a window into the way our brains are wired, experts say. And it may help shed light on disorders related to brain development, like dyslexia, schizophrenia and attention deficit hyperactivity disorder, or ADHD, which are more common in left-handed people.

      Other recent research suggests that mixed-handedness—using different hands for daily tasks and not having a dominant one—may be even more strongly linked than left-handedness to ADHD and possibly other conditions.

      About 10% of people are left-handed, according to expert estimates. Another 1% of the population is mixed-handed. What causes people not to favor their right hand is only partly due to genetics—even identical twins, who have 100% of the same genes, don’t always share handedness.

      King Kale! In Season and Ready to Boost Your Health

      December 11, 2011 /

      It might not make your mouth water to look at it but kale is a major “super food.”

      One of the worlds healthiest foods, kale is both delicious and nutritious.

      Why has kale gotten an edge on all the other dark leafy greens? Tamara Duker Freuman, a dietician and nutritionist with a fantastic blog called What I’m Eating Now, says kale scores a perfect 1,000 on the Aggregate Nutrient Density Index, a food-rating system that measures nutrients per calorie. “While I view the term ‘superfood’ with more than a healthy dose of skepticism (it’s more of a marketing term than a nutrition term), I would be hard-pressed to come up with a food more deserving of the title,” Duker Freuman says of kale.

      Nutritionally, kale has Vitamins K, A and C, and calcium and iron going for it. The distinctive crunch of baked or fried kale is also likely to appeal to people of all ages, says Duker Freuman.

      Here is a delicious recipe for Kale and potato soup; Perfect for cold weather.

      Amazing, Awesome, Avocado!

      December 11, 2011 /

      Avocados have gotten a bad name in the past but undeservedly so.

      High fat and calorie content made avocados a dieters nightmare until recent research revealed the tremendous health and yes, weight loss benefits of this protein rich, belly-fat busting wonder.

      Protein

      Avocadoes provide all 18 essential amino acids necessary for the body to form a complete protein. Unlike the protein in steak, which is difficult for most people to digest, avocado protein is readily absorbed by the body because avocadoes also contain fiber. If you are trying to cut down on animal sources of protein in your diet, or if you are a vegetarian, vegan or raw foodist seeking more protein, avocadoes are a great nutritional ally to include not merely as an occasional treat, but as a regular part of your diet.

      Beneficial Fats

      Avocadoes provide the healthy kind of fat that your body needs. Like olive oil, avocadoes boost levels of HDL (the “good” cholesterol). HDL cholesterol can help protect against the damage caused by free radicals. This type of cholesterol also helps regulate triglyceride levels, preventing diabetes. A study published early this year in the Canadian Medical Association Journal found that a vegetarian diet, which includes HDL fats, can reduce levels of LDL (the “bad” cholesterol) as effectively as statin drugs.

      More Detailed Warnings Necessary on Yaz Birth Control

      December 11, 2011 /

      Yaz birth control pills have come under scrutiny lately.

      The FDA has indicated concern in recent months as some studies, including its own, have shown an elevated risk as the newer synthetic form of progestin called drospirenone, can make women more prone to blood clots.

      Currently, the labels suggest that these contraceptives have blood clot risks similar to those of other birth control pills that combine estrogens and progestins.

      Morgan Liscinsky, an F.D.A. spokeswoman, said the panel “definitely felt that stronger labels were needed, that the labels need to be updated to reflect current data and acknowledge that it is conflicting.”

      Do Men Really Think About Sex All the Time?

      December 11, 2011 /

      Well, men think about sex just about as often as they think about food and sleeping.

      And while women don’t think about sex as often they are not far behind men. And thoughts of food and sleep are proportionately less, as well.

      “The story about this paper that’s been reported in the press has been ‘Men think about sex 19 times a day!’ ” said Terri Fisher, a psychology professor at Ohio State University at Mansfield, and the study’s lead author. But that isn’t all that much when you consider the study’s participants were college students, those repositories of raging hormones and unfettered urges.

      “The more interesting finding is that male college students think just as much about food and sleep as they do about sex,” Dr. Fisher said.
