[A study of taste-sensitivity in pre-school children with special reference to its time-course according to their growth].

Sensitivity to drops of sweet, salty, sour and bitter tasting test liquids was evaluated in 47 kindergarteners (20 males, 27 females). The results revealed that ability for taste discrimination in pre-school children was related to growth and development processes, and was strongly affected by environmented factors mainly dietary lifestyle. Pre-school children showed no sex difference in sensitivity to these 4 kinds of tastes, but displayed gradually increasing sensitivity to sweet and salty tastes from age 3, 4 to 5 on, and gradually decreasing sensitivity to sour taste, while no age-related change was found with regard to bitter taste. Examination of its relationship to dietary habits revealed that taste discrimination became gradually sensitive and to a greater extent at age 3 to 5 for the group that was more careful with weaning and current diets and the group with some family member(s) practicing therapeutic diet treatment, compared with other groups.

[A study on the relationship of taste-sensitivity to salt-restriction in adults].

A survey of the extent of the practice of salt-restriction, duration of such salt restriction, and the ability to discriminate between different degrees of salt content, was performed in a town located in Tottori prefecture Subjects were 20 families (55 persons) where both parents and their adult children had a previous history of hypertension, 38 families (111 persons) where either or both parents had a previous history of hypertension, and 33 families (99 persons) where both parents and their adult children had no history of hypertension. Sensitivity to salt-taste and the relation between the practice of salt-restriction and sensitivity to salt-taste were analyzed. The results are summarized as follows: 1. For persons with histories of hypertension current practice of salt-restriction was significantly greater degree of preference for salt-taste was lower, and the duration of salt-restriction period was longer than those persons without a history of hypertension. 2. Families where both parents and their adult children had histories of hypertension had the highest percentage of these practicing salt-restriction and the largest representation of those who practiced it for a long duration. 3. Those who restricted salt use for a long time also showed a low preference for salt-taste. 4. The sensitivity to salt-taste was much higher in persons who had histories of hypertension than others. 5. Sensitivity to salt-taste was much higher in families where both parents and their adult children had histories of hypertension than others. 6. In families where both parents and adult children had histories of hypertension, significant relationship were observed between parents and their adult children and between husbands and wives in sensitivity to salt-taste.(ABSTRACT TRUNCATED AT 250 WORDS)

Effects of alcohol drinking and cigarette smoking on serum alpha- and beta-carotene concentrations in healthy adults.

The effects of alcohol and cigarette consumption on serum concentrations of alpha-carotene and beta-carotene in 312 healthy male adults, aged from 20 to 58 years, were investigated. Serum concentrations of beta-carotene were lower in alcohol drinkers (17.8 micrograms/dl; 0.33 mumol/l) than in nondrinkers (23.2 micrograms/dl; 0.43 mumol/l). Serum concentrations of alpha- and beta-carotenes were higher in nonsmokers (alpha-carotene: 7.4 micrograms/dl; beta-carotene: 22.6 micrograms/dl) than in current smokers (alpha-carotene: 5.9 micrograms/dl; beta-carotene: 18.4 micrograms/dl). In simple correlation and multiple regression analyses, smoking, smoking and alcohol drinking were inversely correlated with serum concentrations of alpha- and beta-carotenes in healthy adults. In contrast, serum concentrations of alpha- and beta-carotenes rose significantly with an increasing intake frequency of green-yellow vegetables or fruits. In addition, the effect of alcohol drinking on the serum beta-carotene concentration was more pronounced that that of smoking.

Quantitation of serum carotenoid concentrations in healthy inhabitants by high-performance liquid chromatography.

Serum carotenoid concentrations in healthy subjects by age and sex were investigated, as determined by two high-performance liquid chromatography (HPLC) methods. Serum 'carotene' concentrations were 0.655 +/- 0.499 mumol/l 35.2 +/- 26.8 micrograms/dl) for 227 males, and 1,395 +/- 0.780 mumol/l (74.9 +/- 41.9 micrograms/dl) for 370 females. In addition, serum concentrations of alpha-carotene, beta-carotene, and lycopene were obtained from another sample included 356 males and 567 females living in the same area. alpha-Carotene for 356 males was 0.085 +/- 0.096 mumol/l (4.6 +/- 5.2 micrograms/dl), beta-carotene was 0.555 +/- 0.491 mumol/l (29.8 +/- 26.4 micrograms/dl), and lycopene was 0.372 +/- 0.273 mumol/l (20.0 +/- 14.7 micrograms/dl), respectively. Serum concentrations of alpha-carotene, beta-carotene as well as concentrations of lycopene in these inhabitants were significantly higher for females than for males (p less than 0.001).
