Your Complexion Reveals How Good Your Diet and Health Is Researchers have found that your complexion affects how healthy, and therefore how attractive, you appear. What’s more, your diet may be crucial to achieving the most desirable complexion. Using specialist computer software, study participants were asked to manipulate the skin color of male and female Caucasian faces to make them look as healthy as possible. They chose to increase the rosiness, yellowness and brightness of the skin. Skin that is slightly flushed with blood and full of oxygen suggests a strong heart and lungs, supporting the study's findings that rosier skin appeared healthy. Smokers and people with diabetes or heart disease have fewer blood vessels in their skin, and so skin would appear less rosy. But the preference for more golden or 'yellow-toned' skin as healthier might be explained by the 'carotenoid pigments' obtained from vegetables in the diet. These plant pigments are powerful antioxidants that soak up dangerous compounds produced when your body combats disease. They are also important for your immune and reproductive systems and may help prevent cancer. |

Scientists have pinpointed the gene that keeps women 'female', paving the way for a drug that allows menopause to be put on hold.
In landmark research, British and German scientists showed that a single gene is responsible for keeping ovaries what they are. When it is switched off, the ovary starts to turn into a testicle and makes the male sex hormone testosterone. A better understanding of the way the ovary develops could help unravel the condition of premature menopause, a distressing condition that affects hundreds of thousands of British women. It could also one day lead to a drug that puts the ovaries on 'pause', delaying menopause and preserving a woman's stock of eggs until she feels ready to have a family.

Portion Control: The Key to Weight Loss Trying to lose weight? Want to get rid of that gut? Forget about all of those fad diets that severely restrict the number of calories or types of food you can consume. Studies have shown over and over again that they are ineffective in the long-term because not only will you gain back the weight you lost, but you'll probably pack on a few more pounds than you started out with. When trying to lose or maintain your weight, no foods are forbidden so long as you practice portion control and exercise regularly. You see, portion control is the key to weight loss. It is important to enjoy a variety of foods. When you eliminate certain types of food completely, they become more tempting, which may push you to binge on them given the opportunity. |

Lonely Rats More Prone to Breast Cancer CHICAGO (Reuters) - Lonely, stressed-out rats were far more likely to develop breast tumors than rats living in a social group, a finding that suggests loneliness can have a profound effect on health, researchers said on Monday. They said rats that were separated from a social group shortly after birth had a three times higher risk of developing breast tumors than did rats living in a social group, and the tumors in the isolated rats were more deadly. "The leading suspect is poorly regulated stress," Gretchen Hermes, a researcher at Yale University in New Haven, Connecticut, who led the study, said in a telephone interview. Hermes said many studies have suggested loneliness has a negative impact on human health. |

Man-oh-pause For decades, people in the medical profession have been squabbling about whether or not there is a male equivalent of the female menopause. Surely a quick survey of women living with guys in their 50s would have settled the debate in no time. The doctors would have discovered that there is little doubt that hormonal changes wreak havoc with the lives of a significant number of men from around that age. It’s good to know then, that the idea that at least some of the “grumpy old men” out there have a valid medical gripe and aren’t just blaming a fictitious mid-life crisis for their outrageous behaviour is now gradually gaining scientific recognition. |
