M&S to put vitamin D in all their bread products
Marks and Spencer is to add vitamin D to its entire packaged bread range after finding that customers are concerned they are not getting their recommended daily amount.
Every loaf of bread and every bread roll in the M&S bakery range will be made with yeast that naturally produces vitamin D, providing a minimum of 15pc of the daily requirement in two slices.
The yeast will have been exposed to UV light, naturally increasing its vitamin D content, which in turn is transferred into the bread.
The range will be rolled out from next week.
Vitamin D is mostly obtained from the action of sunlight on the skin. Natural dietary sources include oily fish such as salmon, sardines and mackerel and eggs.
It is generally only added to breakfast cereals, margarine and sometimes yogurts and drinks.
