US researchers have created a15-point checklist that can predict the risk of developing alzheimer’s within six years in people who are 65 or older. The risk included predictable factors like older age, low score on cognitive tests, having ApoE4 gene linked to the disease, abnormal MRI findings, thicker carotid artery measurement and other vascular indications. The list also had a surprising risk being under weight, abstaining from alcohol, a history of heart bypass surgery or being slow in doing physical task like buttoning a shirt. a score of eight or higher meant a great risk of developing dementia within the next six years. The study looked at 3,375 people with an average age of 76 who did not have dementia. Fifty six percent of those with high score developed dementia within six hours, compared to 23 percent with ordinary scores and four percent with low scores.

A US study in science has found difference in the brains of people who choose healthy food and those who don’t. The researchers looked at the MRI brains scans of volunteers as they were shown photos of a variety of foods and decided which ones would like to eat. Two sides of the brain work together to give some people the self-control needed to reject unhealthy foods. In people with no self-control, the area of the brain called venromedial prefrontal cortex(VMPFC) consider only the taste factor. But in people with good self control, another area of brain called the dorsalateral prefrontal cortex(DLPFC) becomes active, incorporating health consideration into their decisions helping them pass the chocolate.

A study in the journal obstetrics and gynecology has found that women who keep their ovaries during hysterectomies for benign disease tend to live longer. The study analyzed data on 29,380 women: 16,345 of them had both ovaries removed along with the uterus during hysterectomy, and 13,035 kept their ovaries during hysterectomy. Breast cancer and ovarian cancer are main cause of death among women. Women who had their uterus and ovaries removed before age 50 and did not take estrogen, had an even greater risk of heart disease, strike and death. Since heart disease is a leading killer of woman, the study recommends keeping the ovaries unless you have a strong family history of ovarian cancer or breast cancer.

Newborns, who need support for breathing or resuscitated at birth, may be at risk of having a low IQ. Children, who had to be resuscitated but they did not require any further care, had more risk of having low IQ which is said to be approximately 65 percent and those who were resuscitated and also needed further treatment like neo natal care for brain damage, were more than six times likely to have low IQ even these new born babies are more adaptable to physiological difficulties before or during birth may damage the nerves which are very important for certain specific functions. Thus providing the best for them is needed.

A color coded nutrition labeling system similar to traffic signal, helps consumer identify healthy foods, compared to daily intake system, in which the information is provided numerically. An Australian study at European congress on obesity included 790 people who were randomly exposed to variety of foods, which had a traffic signal light labeling or percentage daily intake labeling. It used red, amber or green dots to rate the nutritional content of the food. The people who participated were five times more likely to identify healthy foods with traffic light labeling than with the percentage daily intake system. This system makes things easier. Hence this is the best.

Men being the weaker sex as women can fight infections better than their opposite sex. a Canadian study in the proceedings of the national academy of science has found that women have very strong immune system, the sex hormone estrogen present in female gives women a more powerful inflammatory response than men, helping them to fight infections. Estrogen seems to block the production of an enzyme called caspase-12 which impedes the inflammatory process, the body’s first line of defense against bacteria and virus, but researchers say that nature devised the strategy to protect the reproductive role of female body, to keep the human race going. Its just dropped the mechanism from the male sex.

A US-based study of 34,480 pregnancies in the journals PLoS medicine has found that taking folic acid supplement at least a year before conception can reduce the risk of premature birth before 28 weeks by 70 percent and before 32 weeks by 50 percent, compared to women who did not take the supplement. The benefits were not seen in those who took the supplement for less than a year before conception. Folic acid supplement are recommended for women because it is known to reduce neutral tube birth defects, such a spina bifida. Another study in the British medical journal has found that folic acid protects against congenital heart defects. There was a six percent drop per year in heart defect among newborns in Canada, since 1988, when the mandatory addition of folic acid to bread, pasta and other grain product began.
