Does a vegetarian diet control Wilson's disease?

The literature indicates that copper (Cu) is less bioavailable from a vegetarian as compared to mixed diet. Further, several groups, including ours, find rather marginal average Cu intake in the typical American diet. For example, our data indicate that Wilson's disease patients on a typical American diet ingest only about 25% more Cu than is required. This suggests that a vegetarian diet, if it reduced bioavailability by about 25% or more, would be an adequate maintenance therapy for Wilson's disease.

Bile acids and pH values in total feces and in fecal water from habitually omnivorous and vegetarian subjects.

Twenty habitually omnivorous subjects and 19 habitually lactoovovegetarian subjects aged 59-65 y collected feces during 4 consecutive days. The concentrations of bile acids in total feces did not differ between the omnivores and vegetarians, but the bile acid concentrations in fecal water were significantly lower in the vegetarians. The concentration of the colorectal cancer-predicting bile acid deoxycholic acid in fecal water was explained by the intake of saturated fat and the daily fecal wet weight (r2 = 0.50). Fecal pH did not differ between the omnivores and vegetarians.

Treatment of proteinuric patients with a vegetarian soy diet and fish oil.

Our aim was to determine whether a longer period of treatment with a vegetarian soy diet with addition of fish oil supplements would accentuate the beneficial effects on hyperlipidemia and proteinuria of nephrotic patients we found in a previous study. After an 8-week baseline period on free diet, patients were randomly allocated either on soy diet alone (SD) or to SD plus 5 g/day of fish oil (SD + FO) orally for two months. Then they crossed over to the other treatment for two additional months. They finally resumed eating the free diet for 3 months.

Apparent absorption of copper and zinc from composite vegetarian diets in young Indian men.

In order to identify the factors affecting apparent absorption of copper and zinc in vegetarian subjects, percent absorption of copper and zinc was estimated during 6 metabolic experiments, each of 2 weeks duration, carried out on 6 healthy young men. They were observed at 3 levels of energy, i.e. 9.2, 10.5 and 12.1 MJ/day. Intakes of zinc were in the range of 20.6-27.1 mg/day and the observed values of apparent absorption (intake-fecal output) were 11.2-20.3%. In case of copper, intakes were 2.7-5.2 mg/day while the apparent absorption was to the tune of 10.6-21.7%.

Good nutrition for the vegetarian mother.

A pregnant or nursing vegetarian mother needs to be aware of the need to vary her diet because the nutrients that she would otherwise get from meat or fish are more widely scattered in foods of plant origin. Diets which exclude dairy products require more careful planning. Particular attention needs to be made to the mother's intake of iron, calcium, vitamin B12 and vitamin D. Vegetarian mothers do not show a higher incidence of complications of pregnancy, but there are some links between vegetarians and lower birthweight and earlier labour.

The influence of a vegetarian diet on the fatty acid composition of human milk and the essential fatty acid status of the infan

Vegan and vegetarian diets supply higher amounts of linoleic acid than those of omnivores. Intakes of alpha-linolenic acid (18:3n-3) are variable, depending on the oils used, but are generally high in vegans. Docosahexaenoic acid (22:6n-3) (DHA) is absent from vegan and many vegetarian diets. Cord plasma and cord artery phospholipid levels of Hindu vegetarians contained less DHA and more docosapentaenoic acid (22:5n-6) compared with those of omnivore control subjects.
