During an endurance run (1,000 km in 20 days) it was investigated whether an ovo-lacto-vegetarian diet (OLVD) could cover the nutritional requirements of endurance athletes. A regular western diet (RWD) was used as reference. Both diets were offered with an energy content of 4,500 kcal per day and an energy percentage of carbohydrate:fat:protein of 60:30:10. The runners were divided into two dietary groups according to their usual dietary habits. The results of the 55 participants who completed the race show that runners from both groups had the same intake of energy, carbohydrate, fat and protein. Runners of the OLVD group consumed more dietary fiber and polyunsaturated fatty acids as well as less cholesterol. With the exception of sodium chloride and cobalamin, the intake of the calculated minerals and vitamins was higher in the OLVD and exceeded the official recommendations. This study shows that an OLVD with a high nutrient density is adequate to cover the nutritional requirements of endurance-athletes. The intake and absorption of iron should be monitored closely in all diet groups.
在一次耐力跑（20天内跑1000公里）过程中，研究了蛋奶素食饮食（OLVD）是否能满足耐力运动员的营养需求。以常规西方饮食（RWD）作为对照。两种饮食的能量含量均为每天4500千卡，碳水化合物、脂肪、蛋白质的能量占比均为60:30:10。跑步者根据其日常饮食习惯被分为两个饮食组。完成比赛的55名参与者的结果表明，两组跑步者的能量、碳水化合物、脂肪和蛋白质摄入量相同。OLVD组的跑步者摄入了更多的膳食纤维和多不饱和脂肪酸，胆固醇摄入量则较少。除氯化钠和钴胺素外，OLVD组计算得出的矿物质和维生素摄入量更高，且超过了官方建议值。这项研究表明，营养密度高的OLVD足以满足耐力运动员的营养需求。所有饮食组都应密切监测铁的摄入量和吸收情况。
