Synopsis
Source of validity: Scientific
Rating (out of 5): 5
Liver is scientifically validated as an effective treatment for night blindness, primarily due to its exceptionally high vitamin A content. Night blindness, or nyctalopia, is commonly caused by a deficiency in vitamin A, a nutrient essential for the formation of rhodopsin, a pigment in the retina required for vision in low-light conditions. The association between liver and improved night vision has deep historical roots; ancient Egyptian and Greek texts describe the use of cooked or raw animal liver as a remedy for night blindness, sometimes even applying liver juice directly to the eyes. Modern scientific understanding confirms the biological basis for these traditional practices: liver, especially from beef or cod, is among the richest sources of preformed vitamin A (retinol). Clinical studies have demonstrated that supplementation with vitamin A rapidly reverses symptoms of night blindness caused by deficiency. The World Health Organization and numerous medical guidelines recommend vitamin A-rich foods, including liver, for the prevention and treatment of night blindness, particularly in populations at risk of deficiency. Thus, both historical tradition and robust scientific evidence support the use of liver for this condition, with the evidence base warranting the highest rating.
