Effects of whey peptides on cardiovascular disease risk factors. 乳清肽对心血管疾病危险因素的影响。

Joel J Pins, Joseph M Keenan
{"title":"Effects of whey peptides on cardiovascular disease risk factors.","authors":"Joel J Pins,&nbsp;Joseph M Keenan","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Previous studies have shown that peptides derived from milk proteins can improve blood pressure. Therefore, the authors tested the blood pressure-lowering effects of a hydrolyzed whey protein supplement rich in bioactive peptides. In a 6-week controlled study, 30 prehypertensive or stage 1 hypertensive subjects (blood pressure >or=120/80 mm Hg and <or=155/95 mm Hg) were randomized to receive 20 g/d of either a hydrolyzed whey protein (active treatment) or an unmodified whey protein (control treatment). Blood pressure, blood lipids, safety measures, side effects, and diet were evaluated throughout the trial. After completion of treatment, a 4-week follow-up was conducted. There was a mean reduction of 8.0+/-3.2 mm Hg in systolic blood pressure (P<.05) and of 5.5+/-2.1 mm Hg in diastolic blood pressure (P<.05) in the treatment group compared with the control group. Low-density lipoprotein cholesterol and high-sensitivity C-reactive protein were significantly improved by treatment. Whey-derived peptides might be a viable treatment option for prehypertensive and/or stage 1 hypertensive populations.</p>","PeriodicalId":520663,"journal":{"name":"Journal of clinical hypertension (Greenwich, Conn.)","volume":" ","pages":"775-82"},"PeriodicalIF":2.8,"publicationDate":"2006-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26406335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
