This book criticizes the 'wildcat schemes' proposed by the Food Ministry in adding vitamin and nutrient supplementation to basic foods. Harris argues that the addition of calcium to bread. He attempts to explain in plain language the medical facts about calcium deficiency (so rare a disease, he argues, that adding calcium to everyone's bread in order to attempt to eliminate it is like burning down a house in order to roast a pig). He additionally explains that adding calcium alone as a supplement does nothing if there isn't adequate Vitamin D to help with absorption.
