“…This type of study must be recognised for having a signalling function. In the case of a shift of children's diets towards lower intakes of meat and/or dairy, nutritional status analyses are needed to confirm adequacy of intakes of Zn, thiamin, vitamin B 12 and probably Fe by the true prevalence of marginal nutritional statuses. Starting from the current consumption patterns of Dutch children, the choice of savoury (e.g.…”

“…Meat and dairy foods were replaced by plantbased foods. Habitual intakes of energy, SFA, protein, fibre, Ca, Fe, Zn, thiamin and vitamin B 12 were evaluated for a reference as well as a 'less meat and dairy' and a 'no meat and dairy' scenario.…”

Objective: Food has a considerable environmental impact. Diets with less meat and dairy reduce environmental impact but may pose nutritional challenges for children. The current modelling study investigates the impact of diets with less or no meat and dairy products on nutrient intakes. Design: Energy and nutrient intakes were assessed for observed consumption patterns (reference) and two replacement scenarios with data from the Dutch National Food Consumption Survey -Young Children (2005)(2006). In the replacement scenarios, 30 % or 100 % of the consumed dairy and meat (in grams) was replaced by plant-derived foods with similar use. Setting: The Netherlands. Subjects: Children (n 1279) aged 2-6 years. Results: Partial and full replacement of meat and dairy foods by plant-derived foods reduced SFA intake by 9 % and 26 %, respectively, while fibre intake was 8 % and 29 % higher. With partial replacement, micronutrient intakes were similar, except for lower vitamin B 12 intake. After full meat and dairy replacement, mean intakes of Ca, Zn and thiamin decreased by 5-13 %, and vitamin B 12 intake by 49 %, while total intake of Fe was higher but of lower bioavailability. With full replacement, the proportion of girls aged 4-6 years with intakes below recommendations was 15 % for thiamin, 10 % for vitamin B 12 and 6 % for Zn. Conclusions: Partial replacement of meat and dairy by plant-derived foods is beneficial for children's health by lowering SFA intake, increasing fibre content and maintaining similar micronutrient intakes. When full replacements are made, attention is recommended to ensure adequate thiamin, vitamin B 12 and Zn intakes.

“…Levels of trace elements in hair have been shown to reliably reflect long term nutritional status [15]. Dietary sources of zinc are mainly from high protein foods such as red meats and seafood, and as such the vegetarian diet is prone to lead to deficiency [30]. High levels of selenium are found in brazil nuts, kidney, seafood and cereals, although this is soil dependent and it has been reported that European intake of selenium is falling [31].…”

Purpose There is increasing concern that environmental chemicals have a direct effect on fertility. Heavy metals such as mercury have been shown to affect various organ systems in humans including nervous system and skin, however they could also act as endocrine disrupting chemicals adversely affecting fertility. Metals such as zinc and selenium are essential micronutrients with diverse functions that may be important for reproductive outcomes. We measured mercury, zinc and selenium levels in the hair, a reliable reflection of long term environmental exposure and dietary status, to correlate with the outcome of ovarian hyperstimulation for in vitro fertilisation (IVF) treatment. Methods We analysed the hair of 30 subfertile women for mercury, zinc and selenium using inductively coupled mass spectrometry. Each woman underwent one cycle of IVF treatment. Correlation between the levels of these trace metals and treatment outcomes was investigated.Results Thirty women were recruited with mean (±SD) age of 32.7(4.4) years and BMI of 25.4(5.0)kg/m 2 . Hair mercury concentration showed a negative correlation with oocyte yield (p<0.05,βcoefficient 0.38) and follicle number (p=0.03,β coefficient0.19) after ovarian stimulation. Zinc and selenium levels in hair correlated positively with oocyte yield after ovarian stimulation (p<0.05,β coefficient0.15) and (p=0.03,β coefficient0.21) respectively. Selenium levels in hair correlated significantly with follicle number following stimulation (p=0.04, βcoefficient0.22). There was no correlation between mercury, zinc and selenium in hair and their corresponding serum levels. Conclusion These data suggest that mercury had a deleterious effect whilst there was a positive effect for zinc and selenium in the ovarian response to gonadotrophin therapy for IVF. Hair analysis offers a novel method of investigating the impact of long-term exposure to endocrine disruptors and nutritional status on reproductive outcomes. Keywords IVF . Heavy metals . Endocrine disruptorsSubfertility affects approximately 1 in 6 couples in the developed world [1], a prevalence that is likely to increase as more women delay childbirth to a later age [2]; approximately 28% of couples investigated for subfertility have a diagnosis of 'unexplained subfertility' [3]. Current treatment largely consists of assisted reproductive techniques (ART) such as IVF or IVF-ICSI, often regardless of the underlying cause. The average success rate of 25-30% for ART in Europe remains unchanged over recent years [4], prompting the search for additional factors which may influence fertility treatments and optimise success, and the identification of adverse factors such as endocrine disrupting chemicals.Capsule Mercury concentration in hair had a deleterious effect where as zinc and selenium had a beneficial effect in ovarian response to gonadotrophin therapy for IVF.

“…There is evidence that well-planned vegetarian diet provides numerous health benefits and is appropriate for all stages of life cycle [2]. Considering health hazards of consumption of protein rich diet deriving from animal sources, proportion of vegetarian or people consuming vegetable-based diet is increasing globally [3], [4], [5], [6]. Global health economy is recently experiencing high burden of chronic diseases as cardiovascular diseases, cardiovascular disease as well as endocrine disorders like diabetic mellitus with sufferings from malignancy [7], [8], [9], [10].…”

Abstract:A cross sectional comparative study was carried out to compare the nutritional status between the vegetarian and non-vegetarian individuals. The study was conducted among 100 respondents (50 vegetarian and 50 non-vegetarian) at Tangail sadar upazilla in Tangail district to assess their nutritional status by collecting anthropometric and socio-demographic data, dietary intake pattern as well as hygienic and clinical information. Among the respondents all the vegetarian were Hindu and majority of the non-vegetarian were Muslim (70%). The study found that nutritional status of 72% vegetarian and 62% nonvegetarian were normal. According to this study 4% vegetarian and 12% non-vegetarian respondents were underweight and 26% non-vegetarian and 24% vegetarian respondents were overweight respectively. Mean heights of vegetarian respondents was 161.62cm and mean weight 59.78 kg whereas mean height and weight of the non-vegetarian respondents were 158.62cm and 57.14 kg respectively. The study observed the food habits of the respondents. Vegetarian respondents consumed more leafy and non-leafy vegetables, pulses, and dairy based products avoiding egg, meat, and fish. Besides 64% non-vegetarian consumed fish and 24% consumed egg daily and 64% consumed meat weekly. The study findings strengthen the notion that the nutritional status of the vegetarian respondents are better than non-vegetarian due to their health consciousness and food intake pattern.
