“…Potential and attainable yield for the main cassava growing areas of Brazil were estimated by Visses et al (2018) using an adapted version of the FAO Agroecological Zone crop simulation model (model 13) ( Doorenbos and Kassam, 1979 ). This is a dynamic, empirical model.…”

“…Tubers are also an important part of the Brazilian diet and are often consumed as a side dish or bread substitute using tapioca. Cassava, also known as mandioca, is an important crop in Brazil, and it is often consumed whole, as part of cooked stews, and in the form of grits or flour, as a side dish [ 2 ]. Cassava flour is incorporated into traditional Brazilian dishes such as ‘Farofa’ and ‘Tutu de Feijao,’ while Cassava starch is used for making a traditional dish called ‘Pao de Queijo.’…”

Background Although tubers play a significant role in Brazilian agriculture, very little is known about the intake of tubers among the Brazilian population. The objective of this study was to characterize the intake of tubers across Brazil. The types of tubers consumed were quantified, and the impact of geographic and sociodemographic factors was assessed. Methods This cross-sectional study is based on dietary intake data of 33,504 subjects obtained from the Brazilian National Dietary Survey. All tuber containing foods were identified, and the contribution of different tubers to overall tuber consumption in Brazil was quantified. Descriptive analyses assessed the impact of macroregion and sociodemographic characteristics on tuber consumption, and differences in intake were assessed using statistical tests. Lastly, the dietary intakes of tuber consumers and non-consumers were compared after adjusting for energy and covariates to determine if there were any major differences in dietary intakes between the two groups. Results Fifty-five percent of the Brazilian population consumed tubers, which differed by macroregion. The intake of tubers among consumers also differed between macroregions. Overall, rural areas reported significantly higher mean daily intakes of tubers (122 g/day) among tuber consumers than urban areas (95 g/day). Mandioca and potato were the most commonly consumed tubers (59 and 43% prevalence, respectively, on any of the 2 days), while the highest daily intakes amongst tuber consumers across Brazil were noted for sweet potato (156 g/day) and potato (95 g/day). On a macroregion level, among tuber consumers, mandioca had the highest prevalence of consumption in the North (94%), Northeast (83%), and Central-West (68%), while consumption of potatoes was most prevalent in the Southeast (63%) and South (62%). Compared to women, small but significantly higher tuber intakes were noted for males (108 vs. 85 g/day). There were no significant differences in intakes among income quintiles. After adjusting for energy and other covariates, nutrient intakes between tuber and non-tuber consumers were not meaningfully different, with the exception of sodium (+ 6.0% comparing non-tuber to tuber consumers), iron (+ 6.1%), zinc (+ 5.7%), vitamin C (+ 8.3%), riboflavin (+ 9.0%), and folate (+ 7.9%). Conclusions Tuber consumption is influenced by regional and sociodemographic characteristics of the Brazilian population. When looking at energy-adjusted nutrient intakes, diets of tuber consumers have resulted in somewhat lower intakes of some micronutrients, namely riboflavin, folate, vitamin C, iron, sodium, and zinc.

ResultsFifty-five percent of the Brazilian population consumed tubers, which differed by macroregion. The intake of tubers among consumers also differed between macroregions. Overall, rural areas reported significantly higher mean daily intakes of tubers (127 g/day) among tuber consumers than urban areas (96 g/day). Mandioca and potato were the most commonly consumed tubers (59 and 43% prevalence, respectively, on any of the two days), while the highest daily intakes amongst tuber consumers across Brazil were noted for sweet potato (156 g/day) and potato (95 g/day).

Compared to women, small but significantly higher tuber intakes were noted for males (108 vs. 85 g/day). Amongst tuber consumers, children aged 10 to 12 consumed fewer tubers than the individuals aged 19 onwards. The highest mean daily intakes were noted amongst tuber consumers in the first income quintile (low earners) and lowest in the fifth quintile (high earners) (P<0.001). After adjusting for energy and other covariates, nutrient intakes between tuber and non-tuber consumers were not meaningfully different, with the exception of sodium (+6.0% comparing non-tuber to tuber consumers), iron (+6.1%), zinc (+5.7%), vitamin C (+8.3%), riboflavin (+9.0%), and folate (+7.9%).ConclusionsTuber consumption is influenced by regional and sociodemographic characteristics of the Brazilian population.
