[Clinical testing of impulse-gustometry as a new method of gustometry (author's transl)].

For the first time in clinical routine testings impulse-gustometry was used in comparison to normal chemical or electrogustometric methods. Loss of taste caused by tympanoplasty, radiation of tumors in head and neck and accompanying facial nerve palsies was tested. The exactly defined location of the stimulus is known advantage in electrogustometry. Impulse-gustometry, however, is able to stimulate different taste sensations like the chemical methods. The sensible sensation, therefore, is eliminated. The stimulating pulses ranged between 0,5 and 2,0 ms at frequencies of 10 to 300 cps. Like with Krarup's method in impulsegustometry there is not always a taste sensation.

Zinc supplementation and its effect on taste acuity in children with chronic renal failure.

Diminished taste acuity (hypogeusia) and zinc deficiency have been reported in children on maintenance haemodialysis and with varying degrees of chronic renal failure. We have studied the effect of 6 weeks' zinc supplementation in 20 children with chronic renal impairment using a double-blind crossover trial. Although we achieved significant increases in serum zinc levels no significant improvement in taste acuity could be demonstrated. These studies provide no support for the belief that routine zine supplements are necessary in children with chronic renal failure.

On the food favoritism of twins.

In the present study, there is a continuation of the authors' earlier investigations concerning food preference/refusal patterns in a group of Hungarian adult MZ and DZ twin pairs. A "Food Like/Dislike Chart" (FLDC), adapted to local nutritional habits, was applied. In order to characterize the degree of intra-pair concordance referring to the food favoritism, the concept of the "Taste Concordance Point" (TCP) was introduced. On the basis of the comparison of the TCP values obtained for the MZ and DZ pairs the conclusion can be drawn that gustatory habits are presumably influenced also by genetic factors. The results allow the possibility of applying TCP to testing zygosity.

Taste perception for phenylthiocarbamide and food choice--a Hungarian twin study.

A total of 98 MZ and 67 like sexed DZ adult twin pairs were studied for taste sensitivity to P.T.C. The MZ pairs were also tested for their food favoritism. A P.T.C. screening test showed a concordance in "tasting" or "non-tasting", within the MZ versus the DZ pairs. For the comparison of food choices of the P.T.C. tasters and non-tasters (members of MZ pairs) a quantity called "Tastership Test Point" (TTP) was constructed. Based on an analysis of the TTP values it may be suggested that taste sensitivity to P.T.C. and food preferences are not completely unrelated characters. These results serve as a contribution to the authors' previous findings obtained in Hungarian adolescents.

Acceptability trials of maize meal fortified with niacin, riboflavin and folic acid.

In Western countries two common and successful measures employed to combat nutritional deficiencies and deficiency diseases are: (i) enrichment of refined cereal products with nutrients lost during milling; and (ii) fortification of common foodstuffs with nutrients the intake of which in the general population is regarded as inadequate. In South Africa in 1978 a committee appointed by the Medical Research Council urged that because of the nutritional situation, particularly among the Black population and more especially relating to pellagra, niacin, riboflavin and folic acid should be added to the staple maize meal. Accordingly, investigations have been undertaken to assess the ability of Blacks to discriminate between fortified and non-fortified maize meals. Studies on groups of adolescents and adults revealed that this ability is not significant, indicating that no problem should be encountered as regards the general acceptability of the fortified product. These findings are in agreement with acceptance by the public overseas of enriched bread and 'corn' products where the latter have been introduced. There is therefore no reason why the milling industry should delay the fortification of all maize meal produced for human consumption.
