Introduction

the chicken egg is a food of high nutritional value and it is important to understand the relationship between egg consumption other common foods of animal and vegetable origin.

Objective

determine the relationship between common foods and egg consumption globally during the years 1961 to 2009.

Materials and Methods

Using FAO databases, per capita consumption of major food groups was extracted and the principal component analysis (PCA) was applied to detect the total percentage of variability and the level of association between groups with predominant animal source intake and those with predominant vegetable and egg source intakes.

Results:

In the 1960’s the egg contributed 14.5 % of intake in its food group, while in the decade 2000, the egg’s contribution to its food groups was just 4.8 %.

Conclusion

Egg consumption trends worldwide have changed over time; in the 1960s and 1970s the egg is ranked as the fifth most consumed food in the world, while in the 2000s it ranked eighth.
