Washington, Feb 19 : A fermented food made from boiled soybeans, which is popular in Asian countries for its ability to protect against heart attacks, has shown promise in preventing the formation of amyloid proteins involved in Alzheimer's disease, say Taiwan researchers.
The study, led by Rita P. Y. Chen has revealed that people in Asia have been eating natto, a vegan food, for more than 1,000 years.
Natto contains an enzyme, nattokinase, which has effects similar to clot-busting drugs used in heart disease.
