In fact, along with her colleague Connie Bales, Starr recently conducted a small study that found that adding extra protein foods to the diet of obese older individuals who were trying to lose weight strengthened their muscles. Participants in the study were separated into two groups—one group was asked to eat 30 grams of protein per meal in the form of whole foods. That meant they were eating 90 grams of protein a day. The other group—the control group—was put on a typical low-calorie diet with about 50 to 60 grams of protein a day.
After six months, researchers found the high protein group had significantly improved their muscle function —almost twice as much as the control group. “They were able to walk faster, had improved balance, and were also able to get up out of a chair faster than the control group,” Starr says. All 67 participants were over 60 years of age, and both groups lost about the same amount of weight. Starr is now looking into whether high-protein diets also improve the quality of the muscle itself in seniors. She's using CT scans to measure muscle size and fat, and comparing seniors on a high-protein diet to those on regular diets. She says her findings should be available in a couple of months.
事实上,斯塔尔和她的同事康妮·贝尔斯最近进行了一项小型研究,发现在试图减肥的肥胖老年人的饮食中添加额外的蛋白质食物可以增强他们的肌肉。研究参与者被分成两组——一组被要求每餐吃30克天然食物形式的蛋白质。这意味着他们每天摄入90克蛋白质。另一组——对照组——每天吃50到60克蛋白质的低热量饮食。
六个月后,研究人员发现,高蛋白组的肌肉功能得到了显著改善,几乎是对照组的两倍。斯塔尔说:“与对照组相比,他们能够走得更快,平衡能力得到改善,而且能够更快地从椅子上站起来。”所有67名参与者的年龄都在60岁以上,两组的体重减轻幅度大致相同。斯塔尔目前正在研究高蛋白饮食是否也能改善老年人肌肉本身的质量。她正在使用CT扫描来测量肌肉大小和脂肪,并将高蛋白饮食的老年人与常规饮食的老年人进行比较。她说,她的研究结果将在几个月内公布。
