title: Controversies about population, clinical or basic research studies related with food, nutrition, physical activity and lifestyle.
abstract: Nutritional studies including food and beverage consumption assessment are needed for different purposes in the field of nutrition, food supply monitoring, toxicology or in the context of intervention strategies that include changes in eating behaviors. Different methods have been used, each with strengths, weaknesses, biases and limitations that must be considered when choosing the most appropriate in each case. The development of new technologies offers exciting developments to improve the validity and accuracy of these methods, as well as their efficiency and commodity. The characteristics of the individuals under study, its environment and the resources available should be considered as well.
