Health Effects of a Vegan Diet

Abstract

This qualitative study aims to understand the health-related aspects of vegan individuals' nutritional preferences and to evaluate the participants' experiences within the framework of the Theory of Planned Behavior. In line with this purpose, interviews with 63 vegan participants addressed the reasons why individuals decided to go vegan, deficiencies encountered in their diet, use of supplements, health effects, social perceptions and sustainability. The study determined that emotional reasons and sensitivity to animal rights were effective in most participants' decisions. It was observed that there were difficulties in accessing dairy products, especially cheese and it was determined that the most commonly used supplements were B12 and vitamin D. When the health aspect of vegan nutrition was evaluated, it was revealed that increased energy and general well-being were the most frequently reported positive effects, but negative effects such as weight gain, iron and B12 deficiency were also experienced. It was understood that the common perception in society regarding vegan nutrition is inadequate nutrition. It was determined that individuals had expectations for increased awareness and product variety for this diet to be sustainable. The study concluded that individuals continued this lifestyle with strong attitudes.
