A study of 110 non-insulin dependent diabetics and 110 controls failed to find evidence that chronic consumption of cassava flour containing significant amounts of cyanide, predisposes to diabetes mellitus. (AU)

The extent of blood glucose increases produced by products of cassava and wheat flour were compared in experiments performed in cats and rats. In normal anaesthetized cats, a meal of 500 mg grated cassava preparation produced a mean maximum blood glucose increase which is 200 percent less than the mean maximum blood glucose increase produced by a meal of 500 mg wheat flour preparation. In diabetic rats, a 20 gm homogenous mixture, consisting of 50 percent cassava bammmy and 50 percent rat chow that was eaten within a 24-hour period, produced a mean blood glucose increase which is 221 percent less than the blood glucose increase produced by a 20gm homogenous mixture, consisting of 50 percent wheat flour bread and 50 percent rat chow and eaten over a similar period of time. The lower glycaemic reponses of the cassava preparations therefore represent significant advantages over wheat flour preparations, for its (cassava preparation) inclusion in the diet of the diabetic (AU)

Threonine and C(1) units from methionine contribute to form an intermediate in the biosynthesis of L-á-(methylenecyclopropyl)-alanine, the toxic amino acid hypoglycin in Blighia sapida. Thereafter, the pathway followed duplicates that for leucine biosynthesis, utilizing identical or analogous enzymes

A procedure for detection and measurement of Hypoglycin A in biological material is described, based on reaction of the amino acid with 1-dimethylaminonaphthalene-5-sulphonyl chloride (Dansyl chloride). The desired flourescent derivative can be separated from others by paper chromatography and measured by flourimetry after elution. Less than 0.2 microgram of hypoglycin A is detectable on chromatograms (AU)

In and around settlements of Lowland Amerindians in Suriname 116 species of food crops were found. Some carbohydrate sources, fruits, nuts and spices are common crops in these settlements. In addition, several vegetable foodstuffs are bought in shops. On the whole the nutritional status of the Amerindians is quite good
