Nutrients In Broccoli Important For Dogs

With a wide array of beneficial nutrients for your dogs diet and particular concentrations of vitamins and minerals, it’s no wonder it’s a favored superfood in a dog’s diet. Here are some of the key nutrients broccoli provides:

  • Calcium
  • Potassium
  • Proteins
  • Vitamin A
  • Vitamin D
  • Antioxidants
  • Glucosinates
  • Biochemical nutrients

Broccoli is referred to as a superfood because it’s chock full of fiber and important nutrients including calcium, potassium, protein, beta-carotene, and vitamin C, as well as vitamins A and D. This makes it a powerful ally in the fight against inflammation and it supports the health of organs like skin, eyes, and heart. It also has anti-allergy and anti-microbial properties.

Beyond promoting good overall health, broccoli also contains antioxidants. It is rich in glucosinates, which break down into biologically active compounds that have anticancer properties. These compounds make carcinogens inactive, protect cells from DNA damage, prompt cell death in tumors, and prevent the formation of tumor blood vessels.

As if that’s not enough, broccoli contains at least three biochemicals that help to protect against cancer and support the immune system.
