A Comparison of Food Supply from 1984 to 2009 and Degree of Dietary Westernization in Taiwan with Asian Countries and World Continents

Abstract EN

Objective.

To compare quality, quantity, and trends of food supply from 1984 to 2009 and degree of food westernization in Taiwan with Asian countries and world continents by using food balance data.

Methods.

We compiled data from food balance sheets of Taiwan and Food and Agriculture Organization, including five continents and three most populated countries each in Eastern, Southern, and Southeastern Asia over the period 1984–2009.

Quantity of food supply per capita was referenced to Taiwan food guides.

The population-weighted means of food supply from Europe, North America, South America, and Australia and New Zealand continents in terms of energy and nutrient distributions, animal/plant sources, and sugar/alcohol contribution were used as indicators of westernization.

Trends of food supply per capita of six food groups were plotted, and linear regression was applied to evaluate food changes.

Findings.

Taiwan’s food supply provided sufficient quantity in food energy, with the lowest cereals/roots supply and rice to wheat ratio, but the highest meat and oil supplies per capita among the 10 studied Asian countries.

Taiwan food supply showed the most westernization among these countries.

Conclusion.

Food supply of Taiwan, although currently sufficient, indicated some security problems and high tendency of diet westernization.
