Retinol activity equivalent (RAE) is the unit used to measure the vitamin A content of foods, as it takes into account the conversion of different forms of vitamin A (such as beta-carotene) to active retinol in the body. Active retinol unit (ARU), retinol functional equivalent (RFE), and functional retinol unit (FRU) are not commonly used units for measuring vitamin A content in foods.
