- Abstract
The contributions of biodiversity to the nutritional safety remain insufficiently studied. To estimate the effects on the health of food taken in the environment a questionnaire of food frequency (QFA) was developed. A review of the food resources allowed to develop a questionnaire to compare the food of 200 individuals of more than 60 years Bënë and Fang, settled in a savannah and rainforest. The evaluations of consumption by QFA confirm studies by weighing. The productivity in degraded forest favors an energy densification of the diet (plantain, tubers, cereal) and an impoverishment of proteins and micro nutriments contributions (low consumption of spinach/Cucurbitaceous/legumes); The installation in forest favors a diet densification in fibers/ micro nutriments (nuts, marrows of lianas, wild/cultivate vegetables) and in animal proteins. This contribution to the food safety can join to energy deficiencies (starchy foods). These diets which favor prevalence of the respectively 2,7 and 6,8 times lower obesity and high blood pressure (cf. DHS, STEPS) can improve micro nutriments contributions in urban context. The QFA confirms inquiries by weighing and allows to develop new hypotheses on the transformations of the forest food practices.
