Major social and economic changes in
Brazil
– Modification in the dietary patterns
• Reduction in the
• Increase in the
consumption of
consumption of
traditional foods
processed foods
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 sodas
IBGE, 2011
Changes in the
dietary patterns
Uniformity of food
habits
Impairment of food
diversity
Reduction of food
options
Disruption of local
food market and
production systems
Brazilian Dietary Guidelines
healthy diet
regional foods
Brazilian food diversity
obtaining low cost healthy
local food
contributing to environmental
sustainability
empowering family farming
Objective
To compare the food diversity in the Northern
and Southeastern Brazilian regions
(less densely vs. most densely populated)
Methods
Brazilian Household
Budget Survey
2008-2009
Two-stage cluster
sampling design
North
Northeast
Central
West
Income and location
strata
Data collection: 12
months
Southeast
South
Sample units equally
allocated among the
Brazil: 55.970 domicílios
four quarters of the
survey to reproduce Southeast:14.078 domicílios
North:7.611 domicílios
seasonal variations
Northern region
Amazon ecosystem
42% of the country area
8% of the country population
16 millions inhabitants = 74% in urban areas
Population density: 4 inhabitants/km2
Southeastern region
Devastated subtropical forest: Mata Atlantica
11% of the country area
44% of the country population
80 millions inhabitants = 93% in urban areas
Population density: 84 inhabitants/km²
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
• Local names
• Scientific names
– Taxonomy (Pubmed)

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
in Brazil
