[Changes in lipid availability in Venezuela, 1970-1992]

Area of Science:

• Nutrition Science
• Food Science
• Public Health

Background:

• Venezuela experienced significant economic shifts between 1970 and 1992.
• Dietary patterns and nutritional intake are influenced by socioeconomic factors.
• Understanding lipid consumption trends is crucial for public health assessments.

Purpose of the Study:

• To quantify and analyze changes in Venezuelan feeding and nutrition, focusing on lipid availability from 1970-1992.
• To investigate the relationship between Venezuela's economic evolution and dietary lipid patterns.
• To identify food groups contributing most to external lipid dependence and saturated fatty acid/cholesterol intake.

Main Methods:

• Reviewed and adjusted Food Balance Sheets (Hojas de Balance de Alimentos) for methodological consistency (1970-1979).
• Estimated daily per person availability of food for human consumption (DCH) for 1991-1992.
• Analyzed lipid DCH evolution across seven stages, correlating with economic indicators and food purchasing power (PCA).

Main Results:

• Visible Fats, Milk, and Meats were primary sources of saturated fatty acids (89-91% of total DCH).
• Eggs, Meats, Fish, and Dairy were key cholesterol sources (82-89% of total DCH).
• Lipid-originated calories remained under 30%, saturated fats under 10%, cholesterol under 300 mg/p/d, and P/S and M/S ratios near 1.

Conclusions:

• Dietary lipid profiles in Venezuela showed dynamic changes influenced by economic conditions.
• Specific food groups significantly contributed to saturated fat and cholesterol intake.
• Overall lipid intake patterns were found to be favorable for human health during the study period.
