  • Diseases of the Heart
  • The occurrence of certain cancers
  • Immune system problems
  • Diabetes

Vitamin D is necessary for canines to absorb calcium and phosphorus at sufficient levels.

Mushrooms, especially those that have been exposed to adequate sunlight during their growth, have the highest vitamin D content of any plant food.
