Healthier with little effort

My idea, not original, is to add vitamin D to milk, at least during the darker parts of the year, and--here's the original part--not charge extra. In many countries, vitamin D is added to milk by law. It would seem, therefore, not to be an expensive process. Although another company offers very skim milk with supplemented vitamin D, and charges a high price for it, Q Meierienne could be the unique company in Norway to offer not only "real" whole milk but "real" whole milk with added vitamin D! You could call it, subject to restrictions by the advertising and health authorities, "Sunshine in a carton". The obvious advertising slant would be a kitchen on some dark, dreary winter morning, a sleepy child pours a glass of milk and--surprise--a brightly shining stream of milk lights up his/her face as he/she pours. And then some useful and truthful about vitamin D deficiency among, in particular, minority and elderly people.
