What about the Liver?
People usually ask about the safety of liver. It is the liver’s job to neutralize toxins in the body from drugs or other chemicals, so obviously the best choice for liver is the grass fed kind, without added antibiotics or hormones. But don’t let that scare you away from liver: it filters toxins but doesn’t store them. Muscle meats are typically higher in unwanted toxins than liver.
Liver is also known to be one of the most concentrated sources of natural vitamin A of any food. Natural vitamin A works to aid digestion, keeps sex organs/reproductive organs healthy, and is a powerful antioxidant.
Liver is a great source of Folic Acid, B vitamins and especially vitamin B12, which help with fatigue, mental ability and nerve health, as well as preventing anemia.
Liver also contains one of the best, most usable sources for the body, of iron. Iron is necessary for many functions in the body including formation of hemoglobin, brain development and function, regulation of body temperature, muscle activity and catecholamine metabolism, to name just a few. A lack of iron will have a direct effect on the immune system; it diminishes the number of T- cells and the production of antibodies.
Iron is essential for oxygen to the blood cells. The primary function of iron is oxygen transport and cell respiration. For an anemic person, fatigue is one of the most noticeable symptoms. The iron in liver is one of most easily absorbable and usable sources of iron.
Do you have a performance dog? Liver contains an anti-fatigue factor, which is likely to do with improving the oxygen-carrying capacity of the blood cells; increasing endurance and strength in athletes of all species.
Liver contains many nitrogen containing compounds that are building blocks for DNA and RNA. In combination with the B vitamins, this makes it extremely helpful to people with Alzheimer’s or other types of dementia. Dogs can suffer from dementia as well, so be generous with the liver.
While liver is highly nutritious, its precious nutrients are very much affected by heat, so never cook it or the digestive enzymes and nutrients will be lost.
Get liver into your dog’s regular diet at least once a week if possible for maximum benefit of its high levels of nutrients. But don’t overdo it – if you feed liver as up to 5% of your dog’s diet, you’ll be doing great.
