查询词典 nutrient

Preliminary research shows that supplemental vitamin A improves the likelihood that the measles vaccine will provide protection. 6 Vitamin A has, since the 1920s, been the subject of much research into the prevention and treatment of childhood exanthems, particularly measles. 7 This nutrient has a critical role in proper immune function , and there is evidence that supplementation with vitamin A reduces the incidence and severity of, and deaths from, childhood measles. 8 9 The World Health Organization has therefore recommended that children with signs of deficiency receive supplementation with vitamin A. The recommended amounts are 100,000 IU for children younger than one year and 200,000 IU for children older than one year, immediately upon diagnosis, and repeated once the next day and once in one to four weeks.
