Superfoods have recently become a buzzword in the food and nutrition world. They don't have to be some long-lost food that an ancient civilization used to consume and is just now being rediscovered. Superfoods are generally regarded as nutrient-dense foods that have certain health benefits if you eat them regularly. The benefits can range from improving the function of the digestive system to preventing cancer and heart disease. And it doesn't have to be something you have to go out of your way for at the store - a lot of these foods can be found in the produce section of your local grocery store! But what about your dog? Can he benefit from these superfoods, too? Which ones are safe for him to eat?
