Phytonutrients are compounds that give vegetables and fruits their vibrant colours, distinct tastes and smells. Phytonutrients have anti-inflammatory, antioxidative and anti-cancer properties. Red ones (watermelon, cranberries, red bell peppers) have antioxidative properties, orange and yellow (carrot, pumpkin, banana, yellow zucchini) are heart-protective and green ones (broccoli, spinach, kale, cabbage) have cancer-blocking chemicals, etc. While prepping vegetables, boil and blend them before feeding your dog. Including mashed and blended vegetables in your homemade dog food will allow for optimal absorption of nutrients.
