Zinc (Zn) is an essential trace element in the body, and its deficiency causes adverse effects on taste, wound healing, and immunity. Insufficient Zn intake is an issue in our country, which can lead to health problems. Breakfast has been reported to play an important role in nutrient intake and health. To determine the association between breakfast intake and Zn intake, 395 local government employees (193 men and 202 women) were evaluated using a self-administered questionnaire on their lifestyle, health status, and dietary history. The participants were categorized according to their frequency of breakfast intake into two groups : those who regularly skipped breakfast and those who did not. Zn intake was evaluated using the density with energy adjustment (mg/1,000 kcal). Zn intake was higher in females than in males (4.4±0.7 mg/1,000 kcal in males vs. 4.7±0.7 mg/1,000 kcal in females, p<0.0001). In males, Zn intake was significantly lower in the group that skipped breakfast than in the group that didn’t skip breakfast (p＝0.024), but not in females, even after adjusting for age, marital status, work status, physical activity, and smoking habits. In conclusion, our results suggest that skipping breakfast might associate with Zn intake for male workers.
