Broccoli is one of the very low-calorie vegetables; provides just 34 calories per 100 g. Nonetheless, it is rich in dietary fiber, minerals, vitamins, and anti-oxidants that have proven health benefits. Total antioxidant strength oxygen radical absorbance capacity (ORAC) of broccoli is 1632 µmol TE/100 g.
Fresh Broccoli is a storehouse of many phytonutrients such as thiocyanates, indoles, sulforaphane, isothiocyanates, and flavonoids like beta-carotene cryptoxanthin, lutein, and zeaxanthin私人电影网.
