Changes in food consumption in Brazil

Area of Science:

• Nutrition Science
• Public Health
• Food Science

Background:

• Eating habits in Brazil have evolved significantly over recent decades.
• Data from national surveys (1961-1988) track these dietary shifts.
• Socioeconomic and epidemiological factors influence food consumption patterns.

Purpose of the Study:

• To analyze changes in Brazilian food consumption and macronutrient intake.
• To identify trends in staple food, protein, and fat consumption.
• To highlight the need for studies on the health impacts of these dietary changes.

Main Methods:

• Analysis of data from Family Budget Surveys and the National Study of Family Expenditure.
• Examination of macronutrient contributions from carbohydrates and fats.
• Assessment of shifts between animal and vegetable protein sources.

Main Results:

• Decreased consumption of staple foods (beans, rice, manioc flour), pork, lard, and butter.
• Increased intake of chicken, eggs, dairy products, and vegetable oils.
• Shift in urban areas towards higher fat, lower carbohydrate diets, with more animal protein and vegetable fats.
• Increased consumption of industrialized foods linked to income.
• Recent trends show reduced intake of fatty/fried foods and sugar, with increased fruit and vegetable consumption in São Paulo.

Conclusions:

• Brazilian dietary patterns have transformed, marked by a move away from traditional staples towards processed and animal-based products.
• Growing health consciousness is driving a recent shift towards healthier food choices, including more fruits and vegetables.
• Further research is crucial to understand the nutritional and health consequences of these evolving eating habits in the Brazilian urban population.
