"The hero of any meal"
The term “offal” refers to those parts of an animal that are used as food but are not skeletal muscle: internal organs such as heart, liver, and lungs, as well as all abdominal organs and extremities, such as tails, feet, and head, including brains and tongue. Blood and tripe are also classed as offal.
Offal is a great source of protein, and some organs, especially the liver and kidneys, are very valuable nutritionally. It has been proven that pets consuming these foods as part of a sensible diet have superior health to dogs that do not eat them. However, although organ meats are valuable food, they are not required in huge amounts, as they are very rich in nutrients.
Liver is the most concentrated source of vitamin A and should be fed in small amounts on a regular basis. It contains significant quantities of vitamins C, D, E, K, and all the B vitamins, and is an excellent source of minerals such as zinc, manganese, selenium, and iron. Liver also provides a source of good quality protein and essential omega-3 and omega-6 fatty acids.
Like liver, kidney supplies good quality protein, essential fatty acids, many vitamins such as A, D, E, K, and all the B vitamins, as well as iron and zinc.
Heart is also an excellent source of protein, B vitamins, and iron. Although its vitamin content is not as high, it does contain some essential fatty acids and significant levels of taurine which is extremely beneficial for the dog’s heart.
Tripe’s rich chlorophyll content is advantageous in reducing gastrointestinal problems but also contributes to red blood cell and hemoglobin formation while detoxifying your blood and lymph systems. Containing the essential fatty acids omega-3 and omega-6 (linolenic and linoleic acids), proteins, fats and an ideal phosphorous to calcium ratio necessary to facilitating absorption of either nutrient, green tripe also presents a slightly acidic pH level conducive digestion. Green tripe also provides your dog with probiotic called (lactobacilli) or lactic acid bacteria.
Lung is very low in fat but high in protein. Lung is almost fat free.
