HC Deb 21 January 1941 vol 368 c54W
Sir E. Graham-Little

asked the Secretary of State for Air what is the annual expenditure incurred in providing members of the Air Force with a patent product intended to restore to the dietary the vitamin A, which is important in preventing night-blindness, and which is contained in the wheat germ removed in milling from the flour supplied to the fighting forces?

Sir A. Sinclair

There is no general issue of any patent product containing vitamin A, and I am advised that the dietary of the Royal Air Force does not require it. Experiments are, however, being made to determine the value of such a product to personnel engaged on night flying.
