Could a vegetarian diet reduce exercise-induced oxidative stress? A review of the literature.

Oxidative stress is a natural physiological process that describes an imbalance between free radical production and the ability of the antioxidant defence system of the body to neutralize free radicals. Free radicals can be beneficial as they may promote wound healing and contribute to a healthy immune response. However, free radicals can have a detrimental impact when they interfere with the regulation of apoptosis and thus play a role in the promotion of some cancers and conditions such as cardiovascular disease.

A vegetarian dietary pattern as a nutrient-dense approach to weight management: an analysis of the national health and nutrition examination survey 1999-2004.

BACKGROUND:Population-based studies have shown that vegetarians have lower body mass index than nonvegetarians, suggesting that vegetariandiet plans may be an approach for weight management. However, a perception exists that vegetarian diets are deficient in certain nutrients. OBJECTIVE:To compare dietary quality of vegetarians, nonvegetarians, and dieters, and to test the hypothesis that a vegetarian diet would not compromise nutrient intake when used to manage body weight.

Health aspects, nutrition and physical characteristics in matched samples of institutionalized vegetarian and non-vegetarian elderly (> 65yrs).

BACKGROUND:Epidemiological studies indicate that a well balanced vegetarian diet offers several health benefits including a lower prevalence of prosperity diseases in vegetarians compared to omnivores. It was the purpose of the present study to compare nutritional and physical characteristics in matched samples of institutionalized vegetarian (V) and non-vegetarian (NV) elderly. METHODS:Twenty-two female and 7 male V (females: 84.1 ± 5.1yrs, males: 80.5 ± 7.5yrs) and 23 female and 7 male NV (females: 84.3 ± 5.0yrs, males: 80.6 ± 7.3yrs) participated.

Clinical practice: vegetarian infant and child nutrition.

The aim of this review is to give insight on the benefits and risks of vegetarianism, with special emphasis on vegetarian child nutrition. This eating pattern excluding meat and fish is being adopted by a growing number of people. A vegetarian diet has been shown to be associated with lower mortality of ischaemic heart disease and lower prevalence of obesity. Growth in children on a vegetarian diet including dairy has been shown to be similar to omnivorous peers.

Assessment of the influence of vegetarian diet on the occurrence of erosive and abrasive cavities in hard tooth tissues.

INTRODUCTION:The aim of the study was to determine the potential relation between vegetarian diet and tooth erosion and abrasion. MATERIAL/METHODS:The examination included 46 vegetarians and the same number in the control group. Clinical research was carried out in order to detect the presence of abrasive and erosive changes and the level of hygiene in oral cavities. The questionnaire survey concerned dietary and hygienic habits. Statistical analysis of the data was conducted with Chi-square test and Mann-Whitney U test.

A worksite programme significantly alters nutrient intakes.

OBJECTIVE: To examine whether a worksite nutrition programme using a low-fat vegan diet could significantly improve nutritional intake. DESIGN: At two corporate sites of the Government Employees Insurance Company, employees who were either overweight (BMI > or = 25 kg/m2) and/or had type 2 diabetes participated in a 22-week worksite-based dietary intervention study. SETTING: At the intervention site, participants were asked to follow a low-fat vegan diet and participate in weekly group meetings that included instruction and group support (intervention group).
