The inclusion of omega-3 fatty acids in our dietary intake is important for performance and recovery and may reduce the risk of various health issues. Studies have shown the omega-3 fatty acid status of US service members is low. The purpose of this study was to evaluate whether offering fish and omega-3-enhanced foods would increase the Omega-3 Index (O3I). We hypothesize cadets will increase O3I with enhanced omega-3 options more than fish alone. Food service venues at 3 US service academies offered fish and other omega-3 foods to cadets for 12 weeks. Questionnaires were used to collect information on the dietary habits and omega-3 food intake of participants. The O3I of each participant was measured at baseline, mid- (6 weeks), and after data collection (12 weeks) time points. Following the 12 weeks, we found a significant increase in O3I. More specifically, the intake of other omega-3 foods, smoothies (3 per week) and toppings (3 per week), increased O3I in cadets. This study identified a strategy encouraging omega-3 food intake and improving O3I among cadets. These results help us understand how we can more effectively impact military service member nutrition for optimal health and performance.
在我们的饮食中摄入欧米伽 3 脂肪酸对于表现和恢复很重要，并且可能降低各种健康问题的风险。研究表明，美国军人的欧米伽 3 脂肪酸状况较低。本研究的目的是评估提供鱼类和欧米伽 3 增强型食品是否会增加欧米伽 3 指数（O3I）。我们假设，与仅吃鱼相比，提供增强型欧米伽 3 选项会使学员的 O3I 增加。3 所美国军事院校的餐饮场所为学员提供鱼类和其他欧米伽 3 食品 12 周。调查问卷用于收集参与者饮食习惯和欧米伽 3 食物摄入量的信息。在基线、中期（6 周）和数据收集后（12 周）的时间点测量每个参与者的 O3I。在 12 周后，我们发现 O3I 显著增加。具体来说，其他欧米伽 3 食物、冰沙（每周 3 份）和浇头（每周 3 份）的摄入增加了学员的 O3I。本研究确定了一种鼓励欧米伽 3 食物摄入并提高学员 O3I 的策略。这些结果帮助我们了解如何更有效地影响军人的营养，以实现最佳健康和表现。
