Both are rich in fiber, vitamins and minerals, and low in calories. Each does have specific nutritional strengths, however.
Spinach is richer in iron, folate and vitamin A, but broccoli provides more vitamin C and calcium.
In addition, broccoli and other cruciferous vegetables, such as Brussel sprouts and kale, contain glucosinolates. Glucosinolates are a group of phytonutrients thought to detoxify carcinogens and increase human resistance to cancer. But, before going overboard on either broccoli or spinach, remember that variety is the spice of life and key to good nutrition. Copyright 1999 Baylor College of Medicine. All Rights Reserved.
