Will drinking a glass of turmeric milk every night help in getting full body fair complexion like britishers ?

No, but...: No, drinking various flavorings of milk doesn't alter one's complexion. However, milk is part of a healthy diet. Dairy has lots of calcium and vitamin D. So, if one already eats enough animal fats, buy the nonfat milk. Also, if one drinks sugary drinks, and then switches over to nonfat milk (not chocolate nor strawberry-flavored milk), her generally nutrition improves and may get healthier skin.
