Drinking milk helps reduce the risk of cardiovascular disease, and researchers from the University of Reading found that people who drink athletes’ favorite protein supplements can reduce heart disease and stroke risk. The study showed that the risk of heart disease and stroke was reduced by 8% in subjects who had mild hypertension by drinking milk supplemented with whey protein. People who take protein supplements have lower blood pressure and cholesterol levels, and their blood vessels are healthier. The study was published in the Journal American Journal of Clinical Nutrition recently. (WeChat laocai Medical Guide: laocaidy) for the British 18 million hypertensive adults, this is undoubtedly a good news. In Britain, 155000 people die every year from cardiovascular diseases caused by hypertension. Although many long-term studies have shown that drinking milk is good for health, little is known about the effect of milk protein on blood pressure so far. The researchers gave the participants high levels of whey protein, similar to what athletes had taken. They found that whey protein produced a very significant effect in the eight week experiment. Currently, the team is further examining the impact of milk protein on other cardiovascular health markers over a longer period. The effects of a daily protein shake for eight weeks on blood pressure, atherosclerosis, cholesterol, and other cardiovascular health markers were investigated. The study used commercially available whey protein powder mixed with water to test another casein supplement different from milk protein, and the use of a supplement containing maltodextrin as a control group, using a randomized, double-blind, three crossover diet intervention. This experiment measured 38 mild hypertension subjects and found that many markers related to cardiovascular health have undergone positive changes, including: eating protein shakes after 24 hours, blood pressure has decreased significantly. Compared with the control group, the systolic pressure decreased by 3.9 mm Hg and diastolic blood pressure decreased by 2.5 mm Hg; total cholesterol and triglyceride levels decreased, a type of fat are plasma total cholesterol and triglyceride, increase their level of cardiovascular disease will increase the wind. Compared with the control group, total cholesterol decreased by 5% and triglyceride levels decreased by 12% after eating protein shakes. Whey protein supplements help build muscle, and athletes and fitness enthusiasts often use whey protein supplements as part of their training methods. Participants had 214 thousand calories of protein supplements, accounting for about 10% of the recommended daily energy intake. But their weight did not increase significantly during the eight weeks, because the participants were asked to replace other diets with protein. The findings suggest that whey protein, as part of a healthy diet, plays an important role in reducing the risk of cardiovascular disease, but further studies are needed to confirm these results.
喝牛奶有助于降低心血管疾病风险 来自英国雷丁大学的研究小组发现，普通人饮用运动员所钟爱的蛋白补充剂可以降低心脏病和中风风险。研究表明，通过饮用牛奶补充乳清蛋白，患有轻度高血压的参试者心脏病和中风风险降低了8%。服用蛋白补充剂的人血压和胆固醇水平更低，血管也更加健康。这项研究发表于近日的American Journal of Clinical Nutrition杂志上。（老蔡导医微信：laocaidy） 对于英国1800万高血压成年人来说，这无疑是个好消息。在英国，每年有155000人死于高血压引发的心血管疾病。 虽然许多长期研究表明喝牛奶有益健康，但是到目前为止，评估乳蛋白对血压影响的研究较少。 研究人员给予参试者高剂量的乳清蛋白，类似于运动员所摄取的水平。他们发现在八周的实验中，乳清蛋白产生了非常显著的作用。目前，研究小组正在进一步验证牛奶蛋白在更长时期下对其他心血管健康标志物的影响。 实验考察了每天饮用蛋白质奶昔并持续八周对血压、动脉硬化和胆固醇等一系列心血管健康标志物的影响。 该研究利用市售的乳清蛋白粉与水混合，同时测试另一种不同于牛奶蛋白的酪蛋白补充剂，以及使用含有麦芽糊精的补充剂作为对照组，采用随机、双盲、三交叉试验的饮食干预。 该实验测量了38个轻度高血压参试者，发现与心血管健康相关的许多标志物都发生了积极的改变，其中包括： 食用蛋白奶昔24小时之后，血压有明显下降。和对照组相比，收缩压下降3.9毫米汞柱，舒张压下降2.5毫米汞柱； 总胆固醇和甘油三酯水平降低，总胆固醇及甘油三酯都属于血浆的一种脂肪类型，它们的水平升高将增加心血管疾病的风。与对照组相比，在食用蛋白质奶昔后总胆固醇水平下降了5%，甘油三酯水平下降了12%。 乳清蛋白补充剂有助于形成肌肉，运动健将和健身爱好者常常以乳清蛋白补充剂作为他们训练方法的一部分。参试者摄入的蛋白补充剂包含214千卡能量，约占每日推荐摄入能量的10%。不过他们的体重在这八周内没有明显增加，因为参试者被要求以蛋白质代替其他的日常饮食。 研究人员表示，这项研究结果证实乳清蛋白作为健康饮食的一部分，在减少心血管疾病风险中扮演着重要角色，不过还需要进一步研究来证实这些实验结果。相关的主题文章：
