A study by US scientists suggests that a Soya based drink a day may help post menopausal women to reduce fat.
Abdominal fat is particularly bad for health as it raises risk of heart attacks and diabetes. The scientists looked at the effect of soya, a vegetable protein supplement on the health of 15 women who had gone through menopause.They asked 9 of the women to drink a 120 calorie soya shake a day while 6 were given a dummy shake.
After three months, there was a little difference in weight between the two groups. While those on soya shakes had lost abdominal fat during the course of the study, the other women had put it on.
Writing in the journal Fertility and Sterility, the researchers said the finding would help in improving the health of women who often put on extra fat after menopause. The shakes contain more soya than people would normally eat in their diet and supplements would be needed to get the same effect at home.

A new study has revealed that purified capsaicin, a drug derived from chilli peppers may reduce acute post surgery pain. Researchers at the Juliana Maria Center, Copenhagen, Denmark, conducted tests on patients and found that the drug reduced pain for atleast three days following groin hernia surgery.
The study presented at the American Society of Anesthesiologists 2007 Annual Meeting in San Francisco, included 41 men undergoing open (not laparoscopic) groin hernia repair with mesh. Half of the men received 1,000 micrograms of ultra purified capsaicin, an odorless, flavorless substance directly into their wounds during surgery. The remaining patients were given a placebo.
All of the study participants received ibuprofen and acetaminophen. After the research, it was found that patients in the capsaicin group had significantly lower pain scores during the three days following surgery, compared to the patients who had received the placebo.
There were no significant differences in average pain scores after this period.The findings showed pain relief “without any clinically important side effects,” said study author Eske K Aasvang, MD, anesthesiology research fellow, Juliana Marie Centre, Copenhagen, Denmark. “The potential for a much longer duration potentially weeks of pain relief induced by a single administration of ultra purified capsaicin should be investigated in patients with severe postoperative pain,” said Dr. Aasvang.

Sugar, Carbs, Fat- these are contributors to unwanted weight. And now adding to this is lack of sleep.
According to a recent study carried out by researchers in the US, people who get less sleep at night are more likely to choose food the next day that will put on extra pounds.
“It’s possible people are less motivated to make healthy food choices when they are really tired,” said Tony Wells, a graduate student who co-wrote the study with Dr. Dean Cruess in the Psychology and Health journal.
In fact, the researchers at the University of Pennsylvania came to the conclusion after recording the sleep hours and food intake of 50 undergraduates over a period of four days and calculating the number of calories in meals. In the first night, the participants slept for eight hours while in the second night, they slept for four hours or less. On the following day, the researchers found that the sleepy students mainly chose foods based on convenience, whatever was easiest to prepare or buy.
