1 Overprotective Parents May Slow Kids’ Brain Growth

Stifling your kids? You may be damaging their brains, according to a new Japanese study which found a link between overprotective parents and defects in a part of their childrens’ brains. Kosuke Narita, who led the study, scanned the brains of 50 young people who also filled out a survey about their parental relationships while growing up. Those whose parents were controlling or overprotective, or who had neglectful fathers, showed less gray matter in the prefrontal cortex, which is connected with schizophrenia and other mental illnesses. Scientists attribute this abnormality to the release of an excessive amount of the stress hormone cortisol. The controversial study is being challenged by some researchers for not taking other factors, such as socioeconomic status, into account.

You Are What You Eat

2 Like Salt or Sweets, the Human Tongue Can “Taste”

Scientists have long known that the human tongue can detect the tastes of salt, sour, bitter, sweet and umami (foods rich in protein.) Now, new research published in the British Journal of Nutrition indicates that we can also discern the taste of fat. In addition, scientists found that sensitivities vary from person to person and that those with a low sensitivity to the taste of fat were more likely to be overweight. Researchers believe this new knowledge could help people lose weight. Said researcher Dr. Russell Keast, “We are now interested in understanding why some people are sensitive and others are not, which we believe will lead to ways of helping people lower their fat intakes and aid development of new low fat foods and diets.”
