Chopping and lightly stir-frying your broccoli may increase the amount of a specific antioxidant, called sulforaphane, thereby maximizing the health benefits you get from the vegetable, research suggests.

The paper, published in the Journal of Agricultural and Food Chemistry , raises the question of whether there are “right” and “wrong” ways to cook broccoli.

The study found that cooking inhibits another enzyme called myrosinase, which is essential for sulforaphane production. Therefore, longer, harsher cooking methods result in a greater reduction in su
