ABSTRACT

The aim of this paper is to evaluate dietary habits and behavioural factors related to atherosclerosis in Slovak Romany, the large minority, characterized by high cardiovascular morbidity. The study involved 150 Romany volunteers (68 males, mean age 42.1 +/- 13.9 y and 82 females, mean age 40.9 +/- 13.7 y). Dietary data were obtained by a validated food-requency questionnaire and a single 24-hour dietary recall. The nutrient intake and health behaviour of the Romany population is not consistent with current guidelines for atherosclerosis prevention. The mean intake of fat is higher than the recommended dietary allowance (RDA), especially in males (155.3 % of RDA). In females the intake of alpha-linolenic acid is low, in males the cholesterol content of the food exceeds the acceptable value. The mean intake of protein is higher than the recommendation (males 153% of RDA, females 122.2%), with a high proportion of animal protein. In both sexes the mean intake of vitamins is below the RDA. In comparison to the general population the diet of the Romany males contains significantly more animal protein (p < 0.05), less plant protein (p < 0.05) and folate (p < 0.01). In the diet of the Romany females a significantly lower intake of plant protein (p < 0.05) and vitamin E (p < 0.05) was observed, as well as a lower intake of linoleic acid and iron in both sexes. The cumulation of ten selected cardiovascular risk factors showed that particularly the Romany males could be considered as having more atherogenic profile.

ABSTRACT

Cadmium is a toxic element ubiquitous in the environment, which damages biological systems in various ways. The major source of cadmium exposure is food. High cadmium content in the soil leads to high cadmium concentrations in certain plants such as grains (above all surface layers and germs), oil or non-oil seeds, fruit and vegetables. These food commodities are the crucial components of a vegetarian nutrition. Blood cadmium concentrations were measured in two non-smoking population groups: the vegetarian group (n = 80) and the non-vegetarian (control) group of general population on traditional mixed diet (n = 84). The significantly higher blood cadmium content (1.78 +/- 0.22 vs. 0.45 +/- 0.04 microg/l) was measured in vegetarian group. Healthy risk values > 5 microg/l were found in 6 vegetarians vs. no non-vegetarian. The highest cadmium concentration (3.15 +/- 0.77 microg/l) was measured in vegan subgroup (plant food only, n = 10) and that value decreased with increasing animal food consumption (1.75 +/- 0.36 microg/l, lactovegetarian and lactoovovegetarian subgroup/added dairy products and eggs, n = 41/, 1.34 +/- 0.21 microg/I, semivegetarian subgroup /as a previous subgroup and added white meat, n = 291). Risk vegetarians vs. non-risk vegetarians consume significantly higher amounts of whole grain products, grain sprouts and oil seeds. Blood cadmium content is directly influenced by age (r = 0.32, p < 0.001), by whole grain product intake (r = 0.66, p < 0.001) and by duration of vegetarianism (r = 0.5, p < 0.001). Oxidative stress plays a major role in chronic cadmium induced hepatic and renal toxicity as well as in other consequences of cadmium injuries. Vegetarians have significantly higher plasma concentrations of natural antioxidants. The sufficient antioxidative protection against cadmium induced free radical formation in vegetarians may inhibit the harmful effects of greater cadmium intake from plant food.
