NUTRITIONAL RESEARCH

Of interest to tho housewife and planner of tho family menus is the recent announcement of the TO. search findings of Dr. R, Gordon ARnew that sound teeth 10 pri- narily a matter of correct eating. OfPorinR the first 100 per cent proof that tooth decay is primarily caused by tho lack of two esBens tlnn food clements, namely phos. phorus and vitamin D In the diet, pr, Agnew's work is hailed by medical and health authorities ns one Of tho moro important chap: tors in tho history of nutrltional research.
 Chinese Have Perfect Teeth
 Tho findings arc based on ten years of resonrch and experiment, begun in 1929 in connection With pr, Agnew's work on tho faculty of tho College of Dentistry of West China Union University in Chengtu. Examinations showed that the tooth Of certain Chinese tribal people were on tho whole much soundor than tho teeth Of tho average person in this coun- try, and this ln spite of tho fact thut ~thc dniiy brush drill was unknown,
 In unnlyslng somo 5000 diets of Chinese tribnl people, pr. and Mrs, Agncw, nlR co-worker in the rc- sonrchos,, found thnt while there wero variations in whnt tho m. tivcs nte in different parts of tho country, ndoqun;e phosphorus wna Invariably present, Among the Thibotnn tribes, In particular, where tooth decay wns notably ina Frequent, while their dict wllA highly restricted, tho eating of whole, corn, m important nrticlo Of their hnily food, supplied thom with plenty of phosphorus and their out.of-door life assured thom with sulIlclont amount of vita. min D from It's source, the sun,

 Feeding the Teeth
 What tho housewife, anxious to Dlnn balanced meals for hor ram ily which will give them tho ole' mcpts essential to tooth henltl' wants, Of course, is to know which foods she should include In tho daily diet. The phosphorus foods, nrc GEE yolh, milk meats. lcnfy vegetables, and tho seeds, grnins, roots and tubcrs. pr. McCulium advises II quart of milk daily eggs cevernl times q week, q lcafy veg. etabia at least once day. q salad twice . day. and m adequate ad- dItionai amount Of vltamin D daily.
 Vitamin D Is not present in cf' fective amounts In ordinary ioouH; however. with the exception small amounts in egg yolk and summer milk, so that additional sources should he included in the diet. The natural source Is Of course found in tho skin. when rctivtcd by tho ultra n-vioict rays of the sun, but since in this lati- jude the sun-s ultraviolet is sel- com strong enough to afford sufI,cient supply of tho vitamin from this natural source. t must i,c supplemented. Naturally vita min D Is found chiefly In fish oils. certain foods. however. notably anfik and bread. can now be scien- tt,icaIiy enriched with vitamin D so that the housewife may supply ,ln her meni-planning the extra faily amount of vitamin D which the family requires without any great variation in her regular rlcnus.
