根据美国肾脏基金会的说法,你的肾脏每天要清理近200夸脱的血液来产生尿液,尿液储存在膀胱中,然后从体内排出。肾脏和膀胱共同构成人体自然排毒和废物清除系统的高效组成部分。各种各样的食物都有助于这些重要器官的功能。在使用食物治疗肾脏或膀胱疾病之前,请咨询你的医生。
钙
高钙含量的食物可以帮助肾脏减少形成肾结石的草酸盐的含量,草酸盐存在于一些植物性食物中,如欧芹、菠菜、可可和浆果。当草酸盐还在消化道中时,钙就会与它结合,阻止它被吸收。根据美国国家肾脏和泌尿系统疾病信息交换中心,如果你有形成肾结石的倾向,你应该每隔一天从饮食中摄入800毫克钙,以确保足够的钙量来预防肾结石。钙的良好来源包括乳制品,如低脂牛奶和酸奶,花椰菜,羽衣甘蓝和带骨鱼罐头,如沙丁鱼和鲑鱼。
柑橘类
根据2011年4月出版的《公共科学图书馆·综合》(PLoS One)杂志上的一项研究,柑橘类水果可以保护肾脏不受炎症和疤痕组织形成的影响。柑橘类fruits are particularly high in pectin, which contains compounds that have been shown to provide diverse health benefits for the kidneys. In the laboratory animal study, drinking water containing citrus pectin protected laboratory animals from kidney injury. Researchers concluded that citrus pectin may prove to be a useful nutrient, when used on a long-term basis, to prevent kidney injury.
间质性膀胱炎
一些对肾脏有益的食物可能对膀胱不利,尤其是当你患有慢性间质性膀胱炎时。间质性膀胱炎包括膀胱疼痛和尿频。酸性食物,如柑橘类和大多数水果,可能蓝莓和梨除外,都不在对膀胱有帮助的食物清单上,据注册营养师朱莉·拜尔说。相反,多吃碱化食物,如芦笋、鳄梨、花椰菜、绿叶蔬菜和南瓜。吃点杏仁,加点香料,比如罗勒,大蒜,牛至和百里香。
膀胱清洗食物
《自然愈合的处方》一书的作者菲利斯·鲍尔奇说,芹菜、欧芹和西瓜具有天然的利尿作用,有助于清洁膀胱和尿道——尿液从膀胱排出的管道。Probiotic-containing foods, such as yogurt, can help to establish healthy bacteria and discourage pathogens. Also, whey powder -- a protein contained in the liquid portion of milk that is removed during the manufacture of cheese -- provides immune-boosting effects. A study published in the February 2010 issue of the "Journal of Dairy Science" reported on antimicrobial, antiviral and pain-relieving effects of whey protein. Balch recommends taking two teaspoons of whey powder with each meal to improve bladder health.
