Dietary Change in Ribeirinha Women: Evidence of a Nutrition Transition in the Brazilian Amazon?
Year: 2010
Type: article
Study design: Observational Study
Abstract: Research suggests Brazil is undergoing a nutrition transition.However, few studies have examined its occurrence in rural communities in the Amazon.Since the nutrition transition is driven by changes in diet and activity patterns, I compared the dietary intakes of n=54 women collected in 2009, with data on n=23 women in the same communities in 2002.Data were collected over three consecutive days in both 2002 and 2009 using the weighed inventory method.Intakes of energy and all macronutrients were 13-30% lower in 2009.In 2002 mean energy intake was 1805 kcal (32.9g fat, 330g carbohydrates, and 47.6g protein).In 2009 mean energy intake was 1335 kcal (26.4g fat, 232.1g carbohydrates, and 41.9g protein).Energy from fat and protein increased, while energy from carbohydrates decreased.In 2002 local foods provided 65-84% of energy and all macronutrients; in 2009 48% of total energy, 66% of fat, 45% of carbohydrates, 42% of protein came from purchased foods.Manioc products were still the primary source of energy (46.9%) and carbohydrates (65.3%).Local fish was still the primary source of protein (31.4%).The primary source of dietary fat in 2009 was not local fruit, as in 2002, but oil and margarine (23.9%).All local foods except game meat contributed less to the diet in 2009 as intake of purchased foods (beans, rice, baked goods, sugared coffee, oil and margarine, preserved meat, pasta, milk) increased.One factor contributing to the consumption of purchased foods may be receipt of cash from the Bolsa Família program: all receiving households reported spending part of their benefit on food.
