They provide this nutrient through the alpha-linoleic-acid (ALA), which is an essential fatty acid that cannot be made by the body and must be taken in through the diet."

"Like all omega-3 fatty acids, ALA is a cardioprotective fatty acid that is found in the outer membrane of every cell in the body," says Best. "Its presence is important for immune function, healing, lung and heart health. Therefore, when you consume Brussel sprouts you are providing your body with a healthy plant fatty acid and simultaneously protecting against acute and chronic illnesses."

"Just half a cup of cooked Brussel sprouts provides you with 135 milligrams of ALA fatty acid," says Best. "Its low carbohydrate nature also makes this vegetable ideal to add bulk to a low-calorie diet for weight loss."
