“…That they have had an imbalanced diet of long duration is very possible and it could result finally in decreased retinol and retinol transporting protein levels. Such considerations about dietary factors are supported by the findings of other authors, who found certain parts of the population to be chronically undernourished [5,34]. Furthermore, Graham ct al.…”

The serum levels of retinol, RBP (retinol-binding protein) and PALB (prealbumin) were found to be significantly lower in patients with malignant tumors of the head and neck region than in controls. In tumor tissues as well in normal laryngeal mucosa, specific binding sites for retinol and retinoic acid were found. Whereas retinol-binding (CRBP = cellular retinol-binding protein) could only be detected in a few cases, binding for retinoic acid (CRABP = cellular retinoic acid-binding protein) was present in all specimens investigated. The presence or lack of binding sites was not dependent on the actual serum retinol levels. With regard to the antineoplastic role of vitamin A, the reduced serum levels are considered as a possible factor in tumor development and growth. CRBP and CRABP are assumed to be mediating factors for the retinol and retinoic acid action. Since the presence of CRABP is a constant finding, we propose that retinoic acid and its synthetic derivatives with high affinity for CRABP could be appropriate antineoplastic drugs in these tissues.

“…Foods of animal origin generally have a lower vitamin B 6 :protein ratio than vegetable foods [6], whereas animal protein may increase the vitamin B 6 re quirement as compared to protein from plants [28]. Our results also indicate different effects of animal and vegetable protein on the vitamin B 6 status (PLP as well as EAST-AC) and may partly be due to differences in the amino acid composition in these products [29,30].…”

“…On the other hand, our results show that dietary fiber is strongly (r = 0.77) associated with intake of vitamin B 6 , indicating that more vitamin B 6 is ingested with fiber-rich diets. Moreover, vitamin B 6 re quirement depends on the protein content of the diet [6][7][8]. Dietary fiber intake was much more strongly related to intake of vitamin B 6 than to total protein intake.…”

“…Since the customary vegetarian diet is relatively high in fiber [14], insufficient amounts of nutrients may be available from that diet. Schultz and Leklem [15], studying the bioavailability of vitamin B 6 among middle-aged and elderly vegetarian and non vegetarian women by just comparing the vitamin B 6 status of these groups, did not find an adverse effect of crude fiber on vitamin B 6 status. However, a food con sumption pattern consists of a complex set of interrelated nutrients [16].…”

“…Kant et al [5] found lower plasma pyridoxal-5'-phosphate (PLP) levels among elderly people than among younger adults, but no significant differences in vitamin B 6 intake among the age groups were observed (neither in absolute amount nor expressed per gram protein). Since the vitamin B 6 requirement depends on the protein content of the diet [6][7][8], a higher consumption of fruits, vegetables, and potatoes results in a higher vitamin B 6 :protein ratio of the diet and hence is considered to be preventive against a marginal vitamin B 6 status [4]. However, most of these products are rich in dietary fiber, and little is known about the possible inhibitory effect of dietary fiber on the utilization of vitamin B 6 [9][10][11][12][13].…”

To obtain more insight into the effect of dietary fiber on vitamin B6 status among elderly people, we studied dietary interrelationships as well as associations between dietary intake and plasma pyridoxal-5'-phosphate (PLP) and cofactor stimulation of aspartate aminotransferase in erythrocytes (EAST-AC) among 441 nonvegetarian (aged 65-79) and 32 vegetarian elderly (aged 65-94). EAST-AC was found to be inversely related with intake of vitamin B6 and dietary fiber in bivariate regression analyses. After adjustment for age, intake of energy, protein, and fiber, the intake of vitamin B6 was still inversely related with EAST-AC. The association between EAST-AC and dietary fiber disappeared in the multivariate analysis, whereas total protein intake proved to be positively related with EAST-AC in the multivariate analysis only. The differences between bi- and multivariate analyses are most likely due to the observed interrelationships between intake of vitamin B6, fiber, and protein. It is concluded that dietary fiber does not have a significant impact on the vitamin B6 status among Dutch elderly people, since only protein (positively) and vitamin B6 (inversely) intake appeared to be related with EAST-AC in the multivariate analysis.
