Liver benefits

  • 5) High in preformed vitamin A (retinol)

Not only is liver extremely high in vitamin A, but the vitamin A it contains consists entirely or almost entirely of retinol. Retinol is preformed vitamin A, as opposed to pro-vitamin A (e.g. pigmented carotenoid antioxidants) from plant foods.

Compared to provitamin A from plant foods which needs to be converted into the actual vitamin following absorption, preformed vitamin A or retinol from liver does not need to be converted. Not just this, but it has both a higher absorption rate and a higher retention rate, being significantly more bioavailable and thus a better form of vitamin A.

  • 6) Good for high cholesterol

Eating liver can help lower bad LDL (low density lipoprotein) cholesterol and also raise good HDL (high density lipoprotein) cholesterol. The cholesterol lowering properties of liver are owed to a high content of vitamin B3 which studies show both holds benefits for high cholesterol and helps improve cholesterol profile (LDL vs HDL).

The average adult requires 16 mg (milligrams) of vitamin B3 per day. A serving of 100 grams of raw chicken liver, the most accessible of the different types of liver, provides 9.7 mg of niacin which accounts for 60% of daily vitamin B3 values for the average adult. Not just this, but liver is also fairly low in calories and has a modest content of fat which is further good for high cholesterol so long as it’s consumed reasonably.

  • 7) Good food to eat during pregnancy

Liver is one of the best foods to eat in pregnancy. One especially important benefit of eating liver during pregnancy is it helps the baby develop normally. More specifically, liver contributes to the normal development of the brain, spine and spinal cord of the baby in the womb thanks to its generous content of vitamin B9.

How much vitamin B9 in liver? Chicken liver has 588 mcg (micrograms) of vitamin B9 (folate) per 100 grams. The average adult is advised to get 400 mcg of the vitamin a day. This means that a serving of 100 grams of chicken liver provides 147% of daily values for the vitamin.

Studies confirm getting enough vitamin B9 in the diet, whether from foods such as liver or via dietary supplements, helps pregnant women measurably reduce their babies’ risks of neural tube defects which are defects of the brain, spine and spinal cord. Not just this, but the generous content of vitamin B9 in liver is also a source of benefits for the pregnant woman, boosting energy levels and vitality and reducing tiredness in pregnancy.

A keto diet or ketogenic diet is a diet that is low in carbohydrates and high in protein and/or fat. Liver is actually a good food to eat in a keto diet. A serving of 100 grams of raw chicken liver has less than 0.8 grams of carbohydrates, but close to 17 grams of protein and under 5 grams of fat. Whether you are high protein-low fat keto or high protein-high fat keto, liver can represent a good option for a keto meal in both instances.

This means that you can introduce liver into your weight loss diet for added nutrition and variety, without risking weight gain.

At the same time, liver has a great content of protein to help with lean mass acquisition and boost metabolism. Eating higher protein helps with muscle gain which, in turn, burns more calories and supports the weight loss efforts.

  • 11) Eating liver preserves good vision

Liver helps maintain retina and cornea health via a high content of vitamin A and vitamin B2.

One of the most surprising benefits of eating liver has to be its benefits for eyesight. Liver is good for eyesight for two reasons: one, it’s high in vitamin A, and two, it’s high in vitamin B2. Vitamin A exerts important antioxidant activities at the level of the retina, protecting against damage from sunlight which causes loss of visual acuity.

Vitamin B2 is needed for cornea heath and for metabolizing preformed vitamin A, retinol, into retinoic acid, a specific vitamin A metabolite needed to perform various vitamin A function in the body.

  • 12) Lower risks of stroke and cancer if you eat liver

Despite meat, and red meat in particular, including organ meat, being associated with higher risks of cancer and cardiovascular disease, limited intakes in fact exert protective effects against both cancer and cardiovascular disease.

Liver is also naturally extremely high in vitamin A which has scientifically proven immunomodulating activities and antioxidant effects, important for supporting the immune system function and scavenging free radicals, and initiating reparative processes to combat oxidative damage. A deficiency leading to immune system depression increases risks of various cancers.

  • 13) Counteracts skin damage and inflammation

Vitamin A in liver is directly involved in skin cell renewal and skin cell differentiation and exerts antioxidant and antiaging effects. Vitamin A acts as an antioxidant, scavenging free radicals, and combats associated cell damage, initiating reparative processes conducive to a healthier, more youthful skin.

Vitamin B9 in liver also helps with cell division, while vitamin B12 helps with DNA repair. Vitamin B3 is effective against dermatitis, skin thickening, skin inflammation and hyperpigmentation due to sun damage. Vitamin B2 also contributes to skin health, preventing rashes and inflammation of the skin.
