Abstract: ［Abstract］Objective To learn dietary and nutritional status of the toxic diffuse goiter（GD） patients in Yunnan region， to investigate dietary nutrition intake levels of GD patients. Methods By using food frequency method and self-programmed food frequency table， GD patients' dietary nutrition was investigated. We calculated GD patients' intake of all kinds of food and a variety of nutrients per capita per day， and compared them with the suggested values in Chinese residents balanced diet pagoda and dietary nutrients reference intakes（RNIs）; measured the patients' body weight， height and calculating body mass index in the field. Results （1）Dietary structure: GD patients' food intake kinds were various in Yunnan region，the intakes of cereals， tuber crops， meat， poultry， oils and fats and nuts were high; the intakes of vegetables， homonemeae， fruits， eggs， fish and shrimp， milk and milk products were low. （2）Energy and nutrient intake: the energy contribution from fats exceeded the recommended value， the energy contribution from carbohydrates was lower than the recommended value， the intakes of dietary fiber， vitamin A， thiamine， riboflavin， calcium and sodium were low， the intakes of vitamin E， phosphorus and iron were high. （3） Physical examination: GD patients' marasmus rate， overweight rate and obesity rate were 25.2%， 7.0% and 1.7%， respectively. There was no statistically significant difference between males and females（P＞0.05）. Conclusion　GD patients' food intake kinds are various in Yunnan region， but the dietary structure is unreasonable.
