“…Higher carbohydrate (when expressed either as an absolute amount or as a percent of total daily calories) and fiber intake among vegetarians in comparison to omnivores in the present study is consistent with findings in other studies [10,39,41,42,43,44]. As these studies have been conducted in the general population, the present study contributes to the literature by demonstrating that this dietary pattern can be extended to endurance athletes as well.…”

Cardiorespiratory Fitness and Peak Torque Differences between Vegetarian and Omnivore Endurance Athletes: A Cross-Sectional Study

In spite of well-documented health benefits of vegetarian diets, less is known regarding the effects of these diets on athletic performance. In this cross-sectional study, we compared elite vegetarian and omnivore adult endurance athletes for maximal oxygen uptake (VO2 max) and strength. Twenty-seven vegetarian (VEG) and 43 omnivore (OMN) athletes were evaluated using VO2 max testing on the treadmill, and strength assessment using a dynamometer to determine peak torque for leg extensions. Dietary data were assessed using detailed seven-day food logs. Although total protein intake was lower among vegetarians in comparison to omnivores, protein intake as a function of body mass did not differ by group (1.2 ± 0.3 and 1.4 ± 0.5 g/kg body mass for VEG and OMN respectively, p = 0.220). VO2 max differed for females by diet group (53.0 ± 6.9 and 47.1 ± 8.6 mL/kg/min for VEG and OMN respectively, p < 0.05) but not for males (62.6 ± 15.4 and 55.7 ± 8.4 mL/kg/min respectively). Peak torque did not differ significantly between diet groups. Results from this study indicate that vegetarian endurance athletes’ cardiorespiratory fitness was greater than that for their omnivorous counterparts, but that peak torque did not differ between diet groups. These data suggest that vegetarian diets do not compromise performance outcomes and may facilitate aerobic capacity in athletes.

“…There was a large fall in intake from rural Negroes to Caucasians. Our data on rural and urban Negroes, and on Caucasians, agree with values reported by others (Lubbe, 1971;Hardinge et al, 1958). However, differences in mean intake between urban Negroes, Coloureds, Indians and Caucasians were not large.…”

SummaryInformation on appendicectomy-prevalence was secured on 15,317 16-20-year-old South African pupils and students-Negroes, Coloureds (Eurafricans), Indians and Caucasians. Data were also obtained on crude fibre-intake, frequency of defaecation, and transit-time of digesta.Among students, 18-20 years, appendicectomy was very uncommon in rural Negroes (0-5%.) and periurban Negroes (0-9y/), slightly more common in urban Negroes (1F4y.), but very common in Caucasians (16-5%); prevalences in Coloured and Indian groups were low (1F7 and 29%y). Rural Negroes had a far larger fibre-intake, greater frequency of defaecation, and much shorter transit-time; yet, in the four ethnic groups in urban areas, despite wide differences in appendicectomy-prevalence, data on these variables were similar. Differences in other aspects of the bowel milieu int6rieur must therefore be sought. Corresponding studies were made on 1325 Caucasian pupils in Homes; their diet is less sophisticated (in respect of fibre, sugar and fat-intakes) than that of the general population. Pupils had slightly greater defaecation-frequency, lesser transit-time, and an appendicectomy-incidence only 23%/ of that of an appropriate control-group. The conclusion is reached that the causes of appendicitis are wholly environmental.

“…Within the same population groups can be identified with very particular dietary habits, for example vegetarian communities [55, 137,292]. Dietary habits may differ greatly between different regions, and the assessment of differences between traditional diets is easier and more reliable than differences in dietary habits of individuals within the same population.…”

“…Compared to the general American population lacto-ovo-vegetarian and pure vegetarian Americans were found to have 15% and 29% lower serum cholesterol levels [137]. The comparison of a vegetarian community from the Boston area with agedmatched persons from Framingham found 38% lower LDL cholesterol levels in the vegetarians [55,292].…”
