Evidence supporting the use of: Beef liver
For the body system: Eyes
Synopsis
Source of validity: Scientific
Rating (out of 5): 4
Beef liver is justified for supporting the eyes due to its exceptionally high content of vitamin A, primarily in the form of retinol, which is the most bioavailable form of this nutrient. Vitamin A is essential for normal vision; it is a critical component of rhodopsin, a protein in the eyes that absorbs light in the retinal receptors. Deficiency in vitamin A can lead to night blindness and, in severe cases, complete blindness. Scientific studies have consistently demonstrated that adequate intake of vitamin A prevents xerophthalmia and other eye disorders associated with deficiency. Beef liver is one of the richest natural sources of vitamin A, providing amounts that far exceed the daily recommended intake in a single serving. Historical evidence also supports its use: in various cultures, animal liver has been used as a remedy for night blindness long before the discovery of vitamin A. Overall, the use of beef liver to support eye health is strongly backed by nutritional science and clinical data linking vitamin A intake to visual function.
