Effect of Dietary Carbohydrate on the Glucose Tolerance Curve in the Normal and the Carbohydrate-Induced

.LVI to the effect on the body lipid of i 0 tercha nging the dietary carbohydrate from starch to sucrose. The sutbject of the presciit paper is on a different aspect of this ttietary change on the body metabo-lism, nanielv, the glucose tolerance, which iiiay to niy mind, be the underlying cautse foi the changes observed in the lipid me-tabolism. in a 1958-1960 diabetic survey we found that Yemenite Jews have a very low prey-alence of diabetes during the first years aftei their arrival in Israel; however Yem-enite Jews residing in the country for 25 years or more have manifested the disease with a considerably higher frequency, com-parably as high as among immigrants from Western countries (1). In a dietary survey made among the Yemenite Jews (new-comers anti old settlers) the main change in the diet has been the diminished con-suimption of bread and increased intake of sugal- by die old settlers (2). The glucose tolerance of the organism can be affected by previous states of nit-trition (3-5). We have fed rats (6) on fully supplied diets of vitamins and proteins bitt changed the type of carbohydrate, starch versus sucrose. After feeding thi
