An experimental study of sensitization to peanut has shown that this can be induced in guinea pigs by crushed peanuts ingested daily for three weeks although peanut oil, which is found in some preparations of vitamin D, did not sensitize the guinea pigs, when compared with a control group and a group of guinea pigs that had received only a "flash" dose of 1 ml peanut oil by the oral route.
