the effects of a 2 year switch from a mixed to a Lactovegetarian Diet on trace element status in hypertensive subjects
European Journal of Clinical Nutrition, 1992Co-Authors: T S Srikumar, Per Arne Ockerman, B Kallgard, Bjorn AkessonAbstract:Trace element status of 20 hypertensive subjects (14 women and 6 men, mean age 52 years) was compared to that of normotensives. The changes in trace element status, body weight and blood pressure after a 2-year switch from a mixed to a Lactovegetarian Diet were also compared between these groups. The concentration of copper in plasma and that of lead in hair were higher in hypertensive subjects than in normotensives, but the concentrations of zinc, magnesium and selenium in plasma, urine and hair were similar to those of normotensives. In the hypertensive subjects, 3 months after the Diet shift there was a decrease in the concentrations of zinc in plasma, hair and urine, that of copper in plasma and hair, of magnesium in urine, of selenium in plasma and hair, and an increase in the magnesium content in plasma and hair. Also the concentrations of mercury, lead and cadmium in hair decreased after the Diet switch. Among the hypertensives, the relative increase of magnesium in plasma was greater than that of normotensives; their relative decreases of selenium and lead in hair were lower, that of cadmium greater and that of copper in urine was lower. Four years after the start of the experiment when most subjects had resumed a mixed Diet, mineral and trace element concentrations in plasma, hair and urine were similar to their baseline levels. Three months after the Diet switch the relative decrease in body weight was more marked among hypertensive women (5%) than in female normotensives (3%), but similar among men of both groups (5%).(ABSTRACT TRUNCATED AT 250 WORDS)

trace element status in healthy subjects switching from a mixed to a Lactovegetarian Diet for 12 mo
The American Journal of Clinical Nutrition, 1992Co-Authors: T S Srikumar, Gunnar Johansson, Janake Gustafsson, Per Arne Ockerman, Bjorn AkessonAbstract:The consequences of a change from a mixed to a lactovcgetarian Diet for 12 mo on trace element concentra- tions in plasma, hair, urine, and feces were studied in 16 women and 4 men. After the Diet shift, intakes of zinc and magnesium did not change but that of selenium decreased by 40%. Three months after the Diet shift, plasma and hair concentrations of zinc, copper, and selenium had decreased but those of magne- sium had increased and the concentrations of mercury, lead, and cadmium in hair were lower. Also, the excretion of zinc, copper, and magnesium in urine, and that of selenium in urine and feces had decreased. Only small changes occurred during the remaining lactovegetanian-Diet period. Three years later trace element concentrations had reverted towards baseline conccn- trations; copper values were similar to baseline concentrations but data for magnesium were slightly higher, and more complex patterns were observed for zinc and selenium. It is concluded that a shift to a Lactovegetarian Diet changes trace element status. Am J C/in Nutr 1992;55:885-90.

change from mixed Diet to Lactovegetarian Diet influence on iga levels in blood and saliva
European Journal of Oral Sciences, 1994Co-Authors: Gunnar Johansson, Lena WiderstromAbstract:IgA concentrations in human plasma, and whole and parotid saliva were measured before and 3 months after a shift to a Lactovegetarian Diet in 20 volunteers (four men and 16 women mean age 44 yr, range 27-61). The major Dietary trends observed were an increased intake of berries and other fruits, vegetables, and dairy products, and a decreased intake of fish, eggs, and meat; biscuits and buns; sweets; alcoholic beverages; coffee; and tea. The consumption of meat, fish, and eggs decreased to zero, showing that the participants had adopted a lacto-vegetarian Diet. There was a decrease in fat, protein, sucrose, and alcohol intake and an increase in total carbohydrate and fiber intake. There was no significant change in energy, retinol equivalent, or zinc intake. Despite this change in Diet, no significant changes were observed between the mixed Diet period and the vegetarian Diet period in IgA in plasma, 253 +/- 52 and 264 +/- 55; whole saliva, 2.5 +/- 0.4 and 2.4 +/- 0.4; or parotid saliva, 0.88 +/- 0.22 and 0.90 +/- 0.20 (mg/100 ml, mean values, 95% confidence interval). Moreover, the Diet change did not alter the secretion rate in whole and parotid saliva, the secretion rate of IgA in whole and parotid saliva, or the protein content of whole saliva. However, the protein content of parotid saliva increased significantly. Thus, this major Diet change was apparently not drastic enough or sustained long enough to cause a change in IgA levels.

faecal elimination of lead and cadmium in subjects on a mixed and a Lactovegetarian Diet
Food and Chemical Toxicology, 1992Co-Authors: Marie Vahter, Gunnar Johansson, Agneta Akesson, B RahnsterAbstract:Abstract Faecal elimination of lead and cadmium in 16 subjects who changed from a mixed Diet to a Lactovegetarian Diet has been studied. The faecal weight increased significantly following the change to the vegetarian Diet, partly because of increased water content. There was a large inter-individual variation in faecal elimination of lead and cadmium during both the mixed-Diet period (range 14 to 118, median 31 μg Pb/day; range 4.5 to 21, median 12 μg Cd/day) and the vegetarian Diet period (range 19 to 136, median 42 μg Pb/day; range 6.1 to 24, median 14 μg Cd/day). There was a tendency towards increased faecal elimination of lead and cadmium following the change to the vegetarian Diet, but the differences were not statistically significant.

calcium balance in young adults on a vegan and Lactovegetarian Diet
Journal of Bone and Mineral Metabolism, 2003Co-Authors: Kathrin Kohlenbergmueller, Ladislav RaschkaAbstract:For people in Western countries, the vegan Diet has the advantage of low energy intake, but the calcium status of this strictly plant-based Diet is still unclear. The aim of this study was to determine the calcium balance of individuals on a vegan Diet in comparison with a Lactovegetarian Diet in a short-term investigation. Seven women and one man, ranging in age from 19 to 24 years, received during the first 10 days a vegan Diet based on plant foods and calcium-rich mineral water and a Lactovegetarian Diet during the following 10 days. Portion size was adapted to the subjects' individual energy requirements. Calcium status was assessed by means of calcium intake in food and calcium output in feces and urine as measured by flame atomic absorption spectrophotometry. In addition, deoxypyridinoline was measured in urine as a marker of bone resorption. The results show a significantly smaller daily calcium intake with an average of 843 ± 140 mg in the vegan versus 1322 ± 303 mg in the Lactovegetarian Diet. Apparent calcium absorption rates were calculated as 26% ± 15% in the vegan and 24% ± 8% in the Lactovegetarian group (NS). The calcium balance was positive both in the vegan Diet (119 ± 113 mg/day) and in the Lactovegetarian Diet (211 ± 136 mg/day) (NS). Deoxypyridinoline excretion showed no significant difference between the two Diets (105 ± 31 and 98 ± 23 nmol/day). The present results indicate that calcium balance and a marker of bone turnover are not affected significantly when calcium is provided either solely by plant foods or by a Diet including dairy products, despite the significantly different calcium intake levels in the Diets. We conclude that a well-selected vegan Diet maintains calcium status, at least for a short-term period.
