A new study in rats reveals black soya beans that a diet rich in could help control weight, lower fat and cholesterol levels, and help in the prevention of diabetes. Researchers have shown that rats fed with 10 percent soya had gained half as much weight as those without. Total blood cholesterol fell by 25 percent and LDL (so-called bad) cholesterol fell by 60 percent. Preventing obesity this way may also aid diabetes prevention.
A once-a-day, short-term treatment with a drug compound substantially improved learning and memory in mice with Down syndrome symptoms, say researchers at the Stanford University School of Medicine and Lucile Packard Children?s Hospital.
