Resistant starch rice wx/ae WE-Mai

In recent years, many health foods and functional foods have been developed to help prevent lifestyle diseases like Type 2 diabetes, heart disease etc. Resistant starch rice wx/ae WE-Mai is one such food, based on the staple of the Japanese diet.

WE-Mai has been developed from a cross between two mutant strains of rice, waxy (wx) (EM21) and amylose-extender (ae) (EM16), which are mutant strains produced by treatment with N-methyl-N-nitrosourea. WE-Mai is not genetically modified, but is developed from rice strains that have been bred and isolated, so it is perfectly safe.
