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)

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) and other sources

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
