Spring Naturals super-premium line of dry dinners have been deemed low glycemic and diabetic friendly by the Glycemic Research Institute. Cat foods with a high glycemic index lead to elevated blood glucose levels. This in turn can increase the risk of epilepsy, hypothyroidism, allergies, yeast infections, cancer and diabetes. Diets formulated with low glycemic ingredients are digested slower than high glycemic foods, allowing all of the nutrients to be properly absorbed. When food is digested slower and the nutrients are properly absorbed, pets will remain fuller longer, which helps maintain weight control. The dry formulas submitted to the Glycemic Research Institute for testing were Spring Naturals Grain Free Turkey Dinner, Grain Free Turkey & Salmon Dinner, Grain Free Chicken Dinner, Grain Free Tuna & Chicken Dinner, and Grain Free Tuna Dinner.
