The aim of this study was to investigate trends in nutrients and sources of dietary intake for Taiwanese people from the Nutrition and Health Survey in Taiwan (NAHSIT) 1993-1996 to 2005-2008. Twenty-four hour dietary recall data were obtained from the 2005-2008 NAHSIT. The results showed that intake of cereals and grains, and dietary fiber has decreased, whereas intake of carbohydrate rich convenience foods has increased. As a result, 10-20 g of dietary fat is now obtained from carbohydrate rich foods. A greater proportion of Taiwanese are choosing low-fat meat products, however, excessive intake of meat by men and women aged 19 to 64 years is resulting in excessive intakes of protein, cholesterol and saturated fat. Men and women aged 19 to 30 years had insufficient intakes of fruit and vegetables. Consumption of fruit, dairy/products, and nuts was low in all age groups. We recommend strengthening public nutrition education and changing diet related environment to improve dietary quality and food group distributions. Issues of concern include excessive intakes of energy and the soybean/fish/meat/eggs food group in all subjects, high amount of processed foods and refined-carbohydrate rich foods in men aged 19 to 64 years and women aged 19-30 years, as well as intakes below the DRI for a variety of nutrients in elderly persons.
