Major social and economic changes in Brazil

– Modification in the dietary patterns

Brazilians combine the traditional diet, based on rice and

beans, with processed foods

low in nutrients and high in sugar, fat and sodium, like

cookies and sodasIBGE, 2011

• Reduction in the consumption of traditional foods

• Increase in the consumption of processed foods

Changes in the dietary

patterns

Impairment of food diversity

Reduction of food options

Disruption of local food market and production systems

Uniformity of food habits

Objective

To compare the food diversity in the Northern and Southeastern Brazilian regions

(less densely vs. most densely populated)

Methods

Brazil: 55.970 domicíliosSoutheast:14.078 domicílios

North:7.611 domicílios 

Brazilian Household Budget Survey

2008-2009

Two-stage cluster sampling design

Income and location strata

Data collection: 12 months

Sample units equally allocated among the four quarters of the survey to reproduce seasonal variations

Data collection

• Food and beverage acquisition for consumption

• Monetary and • Non monetary (donation, production, etc)

– Informed by the person that was responsible by the household expenses

• Recorded in a notebook• Data entry in the households

– specific software– personal interview

Data treatment

• Only fresh foods Cereals Leafy Vegetables Fruity Vegetables Roots and tubers Fruits Coconuts and seeds Red meats Poultry Freshwater fish Marine fish

Number of species

Household availability: number of species in the Brazilian Northern and Southeastern, 2008-2009

Future developments of the research

• Identify the origins of the foods

• To estimate the prevalence of acquisition

• To relate with individual food consumption data

• The major problem to describe food diversity in Brazil is the broad variation of common names for single foods

Information on dietary habits is important to guide food and nutrition policies elaboration
