Dietary Surveys methodologies 2: Requirements (handout) Paton et al 1902, 1913: 3500 Cals per ‘man’ (Atwater’s moderately active) Paton et al 1926: City slum child on 2600 per ‘man’ per day grows after 18 months as fast as country children. Lusk’s standard of 3000 might be reduced to Cathcart 1931: suggest ‘that all families be classified on an arbitrary 2,500 Cal. Scale, and that in the case of manual workers a special addition be made to the male parent’s allowance’ Orr 1936: man values abandoned in favour of ‘a per head basis calculated on the requirements of children, adolescents, and adults, and weighted according to the distribution of these in the total population’. Average per head 2810 Cals. (Stiebeling’s optimal requirements, included requirements for other nutrients) Rowett 1955: used scales devised by the Institute in 1937 and the BMA 1950 scales

Examples of allusions to the capacity / effectiveness of parents ‘The household consists of... an Irishman... the mother also Irish... and four children... The house has two rooms. It is dirty and ill- kept. The table is always littered with crumbs, and tea, and dirty crockery... The meals are irregular. The children drink tea five or six times a-day, and get a piece of bread whenever they ask for it... Things are bought in small quantities...’ (Edinburgh 1902 report)

Extract from ‘A study of social and economic factors in the causation of rickets’, ‘Twenty-nine percent of the mothers of the markedly rachitic children were careless. They were not wilfully neglected, but still the children did not receive sufficient attention. Either the children were not kept clean, their feeding appeared to be irregular and unsatisfactory, or they were allowed to sit for hours at a time on a cold floor or chair...’

Extract from: Studies in nutrition; an enquiry into the diets of families in Cardiff and Reading’ (1932): ‘Smallness of income is only partially responsible. Far more important on the whole than the size of the income is improvidence on the part of one or both parents or simply general incapacity.’

George M’Gonigle in Enough to Eat? ‘... the average working class housewife by rule of thumb methods knows pretty well which foodstuffs to buy to feed her family properly. Though she doesn’t know the difference between a vitamin and a bus ticket our investigations shows quite clearly that as her income increases she approaches more and more nearly to a really satisfactory diet’

Mellanby / Orr on Vitamins/Minerals and infections Hopkins on ‘partial deficiencies’ Mellanby: ‘nothing has been more prominent in recent work … than the part played by correct feeding in increasing the individual resistance to infection... I need only allude to the recent accumulation of facts showing the importance of vitamin A in increasing the resistance of the animal...’ E. Mellanby, ‘Duties of the State in Relation to the Nation's Food Supply’, British Medical Journal, 1927 Orr: ‘The influence which long-continued deficiency of mineral matter … may have upon the incidence of disease, due to microbic infection, is well worthy of consideration …’ J. B. Orr, ‘The importance of Mineral Matter in Nutrition’, Transactions of the Highland and Agricultural Society of Scotland, 1923 Hopkins: ‘it may be said... beri-beri or pellegra or any diseases like them are unknown in this country; and scurvy is … very rare. But disturbances in health may exist without arriving at the extreme stage when the appearance of a severe set of symptoms leads to the recognition of actual disease.’ F. G. Hopkins, ‘The Practical Importance of Vitamins’, British Medical Journal, 1919

First appearances of ‘protective foods’ in the medical weeklies (handout) BMJ 1922 editorial :... diets should be supplemented by vitamin-rich foods, of which the most important are milk and milk products, green vegetables, and fruit-substances which McCollum designates as “protective” foods. Lancet 1923: on a paper by Dr Harold Scurfield, MoH for Sheffield on the nutritional value of watercress: There was just the danger that people would get sick of the talk about vitamins before they had absorbed the comparatively simple teaching of the newer nutrition- viz., that they needed to include more of the “protective foods” - i.e., milk, green vegetables, and fruits-in their dietaries.

First uses of ‘protective foods’ The Times and Hansard (handout) We are being reminded that milk is a perfect food, that it is rich in vitamins, and that it is the only suitable nourishment for young children or suckling babies; it is also a very useful food for adults, and we are doing all that we can to see that this country produces good, pure milk at a cheap price. This food is so valuable that it has been called one of the "protective" foods, the other being green vegetables, because it does not matter how unsuitable or peculiar the diet of an individual may be, or however much a food crank he may be, provided he includes milk and green vegetables in his diet, he will not go far wrong.

Hopkins on practical application of vitamins in medicine “If the practitioner, when considering whether diet may not be the cause of ill ‑ health has in his mind the idea of specific deficiencies he will no longer reject the possibility when general underfeeding or ill digestion alone have been excluded. Realising that details must be considered, he will, in my opinion, be able to ascribe more to diet than hitherto, and at the same time extend his list of cases diagnosed...” F. G.
