Conflict of interest in the training and practices of nutritionists: regulation is necessary/ Conflito de interesses na formacao e pratica do nutricionista: regulamentar e preciso

Transnational "Big Food" companies use advertising strategies to influence nutritionists, professors and students of nutrition. There are, however, conflicts of interest in this relationship. The scope of this study is to conduct a narrative review on the influence of the food industry in training in nutrition. It was revealed that industries seek to induce the recommendation, the prescription and the consumption of products by students and nutritionists through strategies such as sponsorship of scientific meetings, travel funding and the distribution of promotional gifts. However, acceptance of these gifts can generate a moral obligation to reciprocate, thereby jeopardizing the judgment of information and decision on professional conduct. At the University, the advertising occurs mainly through sponsorship of events and research funding, donation of materials and structures and publicity in the classroom. Regulating the conduct of the private sector in the academic arena is essential and, in this perspective, the implementation of regulatory measures to limit the inclusion of the food industry in undergraduate courses in nutrition is recommended to ensure that nutritionists will be better prepared to perform their tasks in and ethical and unbiased manner.
