A Japanese study of broccoli sprouts and liver function has found the sulforaphane-rich food to be highly beneficial. An extract from broccoli sprouts given to male participants was shown to improve hepatic abnormalities and overall liver function significantly.
For the study, the researchers conducted a double blind, randomized placebo-controlled trial of males with fatty liver disease. The subjects received either extract of broccoli sprouts in capsule form, or a placebo. The capsules contained glucoraphanin, a precursor for the sulforaphane in broccoli sprouts.
