A vegan lifestyle may lead to serious nutritional deficiencies: study

With the rising awareness about health and environmental concerns, more and more people are opting for a plant based or vegan diet. Now while this might be done in a good spirit, many nutritionists believe the vegan lifestyle poses a risk of lowering the intake of essential nutrients that are important for the brain health.A recent study studied this phenomenon. The study was published in the journal, BMJ. The article in the study said moving away from diets rich in animal products could have “unintended consequences.”The essential dietary nutrient is critical for brain health, particularly during foetal development, and also influences liver function.But the amount produced by the liver is not enough to meet the requirements of the human body and therefore it must be obtained from dietary and supplement sources.The primary sources of dietary choline are found in beef, eggs, dairy products, fish and chicken.Smaller amounts can be found in nuts, beans and cruciferous vegetables, such as broccoli.Dr Emma Derbyshire, of Nutritional Insight, a consultancy specialising in nutrition and biomedical science, said the Government had failed to recommend or monitor levels of the nutrient.Writing in the online journal BMJ Nutrition, Prevention & Health, she said: “Given the important physiological roles of choline and authorisation of certain health claims, it is questionable why choline has been overlooked for so long in the UK. Choline is presently excluded from UK food composition databases, major dietary surveys, and dietary guidelines.”Supplementation strategies should be considered, particularly during pregnancy, when choline intakes are critical to infant development.She added: “The mounting evidence of choline’s importance makes it essential that it does not continue to be overlooked in the UK. This is now more important than ever given that accelerated food trends towards plant-based diets/ veganism could have further ramifications on choline intake/status.”
