West African countries have made impressive progress in fighting against malnutrition and hunger and ensuring food quality and varying food choices. This paper aimed for the first time to evaluate the determinants of diet choice by the populations of West Africa, especially those of Benin, Togo, and Nigeria. The data collected from 473 people relate mainly to their socioeconomic and cultural characteristics and the factors determining the choice of the diet for which they have opted. These data were analyzed using the Tobit model based on the Heckman method. The statistical analysis of the results obtained allowed us to deduce that the populations studied generally opt for a flexitarian, vegetarian or vegan diet. The age, level of education, religious and ancestral beliefs, social framework, monthly income, perception of the costs generated by each diet, perception of the consumption of products of animal origin such as meat and fish have a significant influence on the choice of diet. The intensity of the chosen diet was determined by variables such as sex, level of education, social framework, perception of consumption of animal products, and meat and fish. Diet being a determining parameter of our state of health, it is imperative to make people aware of the different diets so that they can identify and adopt the one that suits them best.

Food safety has always been and continues to be a major concern for all countries of the world. This concern is all the more perennial in the developing countries like Benin with a low economic level and still rudimentary and extensive agriculture. To reduce a little bit of food insufficiency, is developed urban and peri-urban agriculture based mainly on market gardening. This study focused particularly on the production of onion in southern Benin. It aims to analyze its performance, to understand the importance of this activity but also to see what are the obstacles faced by these producers. Three municipalities were investigated: Grand-Popo, Cotonou and Sèmè-Kpodji. A total of 60 farmers were surveyed at 20 per municipality. Quantitative and qualitative tools were combined for the analysis of data collected through individual and group interviews. A joint analysis approach was used to achieve specific objectives. It consists to combine speech analysis, participant observation with statistical tools such as the frequency distribution, the regression model and calculation of performance indicators. It follows from all of these analyzes that onion production is profitable from a financial point of view. This performance is enhanced by factors such as age, experience and membership of a producer group. Similarly, the farmers claimed for majority that onion occupies a special place in their market garden production. This production improves their socio-economic and food situations. However, the constraints that undermine the more onion production and thus constitute important producer concerns are financial, institutional, organizational, property constraints and those directly related to production. Farmers therefore, expect a little more effort from agricultural policies to improve the development of this sector.
