西柚，即「朱栾」，又称「葡萄柚」，芸香科，原产地西印度群岛。成熟时果皮呈黄色，果肉淡红白色。假如皮粗硬的，味道和水分都会不足。</p>
目前，市场上常见的西柚有3个主要品种。果肉白色的为马叙葡萄柚(Marsh)，又称无核葡萄柚，是多倍体，品种内也有果肉红色的品系;果肉白色的是邓肯葡萄柚，果较大，果皮较厚，种子较多，果肉略带苦味;果肉红色的是汤姆逊葡萄柚(Thompson)。此外，还有的品种果肉为淡黄色或粉红色或近无色透明。</p>
西柚被认为是柚与甜橘杂交的品种。西柚富含果胶，有降低胆固醇的作用，其黄酮类成分也被广泛认为具有抗癌作用。</p>
美国是世界上最大的西柚生产国，中国和南非名列第二和第三。</p>
西柚汁可以作用于某些药物，提高人体对药物的吸收率，这种现象必须高度重视。对于有些需要服药的病患者，假如无法评估西柚对于你正在服用的药物有什么影响，最好的办法是停止食用西柚。</p>

<strong>RDI</strong>是美国的一个标准，指每日需摄入的营养成分，按统计表明足以满足97-98%美国健康人的需求。这个标准也被许多其它国家借鉴。西柚中维生素C含量很高，每100克西柚中的维生素C高达<strong>RDI</strong>的56%。此外，泛酸达到6%，硫胺素、叶酸、维生素B6均达到3%，尼克酸和核黄素分别达到2%和1%。在矿物质方面，每100克西柚中钾达到<strong>RDI</strong>的3%，镁2%，其它铁、锌、磷、钙均为1%。</p>
</div>
此外，西柚中含有宝贵的天然维生素P和可溶性纤维素，是含糖分较少的水果。维生素P，又称芦丁，在对维生素C的消化吸收上是不可缺少的物质。它能减少血管脆性，降低血管通透性，增强维生素C的活性，预防脑溢血、视网膜出血、紫癜等疾病。血管脆性，降低血管通透性，增强维生素C的活性，预防脑溢血、视网膜出血、紫癜等疾病。成年人，尤其是工作繁忙，心情郁闷的人群以及中老年人都需要补充维生素P。</p>
维生素C的主要作用是提高免疫力，预防癌症、心脏病、中风，保护牙齿和牙龈等。维生素C可参与人体胶原蛋白合成，促进抗体的生成，以增强肌体的解毒功能。</p>
<strong>西柚的营养价值</strong></p>
高血压患者常服用降压药，以排除体内多余的钠，维持身体正常的生化代谢平衡，但同时往往又使体内必需的钾流失。而钾对于维护心脏、血管、肾脏的功能，是非常重要的。西柚是少有的富含钾而几乎不含钠的水果。因此，是高血压、心脏病及肾脏病患者的最佳食疗水果。</p>
当人体过多地摄取高脂肪、高热量食物时，营养过剩，血脂增高，大量脂质尤其是低密度脂蛋白黏附于动脉血管内壁，引起动脉硬化，导致心、脑、肾等重要脏器供血不足，引起心脏病或大脑及肾病等病变。西柚含有丰富的果胶成分，可降低低密度脂蛋白胆固醇的含量，减轻动脉血管壁的损伤，维护血管功能，预防心脏病。</p>
研究表明西柚有助降低胆固醇。</p>
西柚还含有天然叶酸。叶酸不但对早期妊娠非常重要，在整个怀孕期也同样必不可少。孕期随着胎儿身体组织迅速成长，孕妇需要大量叶酸来满足胎儿的需要。叶酸缺乏不仅会使妊娠高血压症、胎盘早剥的发生率增高，更会导致孕妇患上巨幼红细胞贫血，出现胎儿宫内发育迟缓、早产及新生儿低出生体重。因此，西柚也是孕期妇女首选的水果。</p>
西柚籽提取物对细菌和真菌有很强的抗菌性能。</p>
西柚中含有大量的亚精胺，可能与寿命有关。 亚精胺是细胞生长和成熟必要的，细胞老化后亚精胺的水平下降。 科学家发现：给蠕虫、果蝇喂食亚精胺使其寿命大大延长。 此外，添加亚精胺到小鼠饮食中降低了衰老的分子标记。在亚精胺培养液中的人体免疫细胞可以生活更长的时间</p>
西柚有助加快骨骼的生长。研究人员将西柚甙连同骨胶原植入兔子骨骼中的受损部分，经比对后发现西柚甙可刺激细胞中的造骨基因，促进骨骼生长及增生达四倍，是一种安全的骨诱导剂。</p>
<strong>西柚的食用方法</strong></p>
西柚除了作为水果食用和加工成为糖果和甜食以外，还有一些典型的食用方法。</p>
<strong>西柚虾沙律</strong></p>
材料：素虾仁1斤，西柚、鳄梨各1个，生菜1棵，沙律酱2汤匙，番芫荽少许。</p>
做法：</p>
1、素虾仁煮熟。
2、西柚去皮，切片;鳄梨取肉，切片。
3、生菜洗净，沥干水分，撕成大片。
4、生菜叶垫碟，排上西柚片、鳄梨片及素虾仁即成。沙律酱伴食，番芫荽装饰。</p>
<strong>西柚茶</strong></p>
一个西柚，洗干净了以后把它切成一小块一小块的然后浸泡在蜂蜜里。</p>
为了最大限度的保留西柚的果汁，把西柚切成六角，然后再把西柚汁尽可能多的挤在瓶子里。接下来将西柚皮和果肉用刀分开。</p>
西柚皮最好用榨汁机榨一下，没有榨汁机的话，也可以把皮尽切成尽可能小的块。都弄好以后，放入蜂蜜，搅拌均匀。西柚的果肉是红色的，做成西柚茶以后是粉红色的十分好看。喝的时候，你会发现来西柚皮也是这样的甘甜可口。</p>
<strong>西柚的食用禁忌</strong></p>
对于不必服食任何药物的健康人来说，西柚是一种非常好的水果。</p>
1989年美国化学家Bailey等首先报道了西柚汁影响处方药物菲洛地平的口服生物利用率，这一发现引起了广泛关注。在相当数量的人死于药物过量后，西柚和苦酸橙与他汀类药物的相互作用才广为人知。进一步研究表明西柚汁并不是直接与这些药物发生作用，而是通过对一些氧化代谢酶的调控来其作用的，这种酶就是细胞色素P450。尽管不同药物在化学成分好药理特性上有差异，但是它们在人体内的代谢途径都是通过肠道内的CYP3A4调控进行的，CYP3A4可部分地催毁药物，加速药物成分在肠道内的分解，以致降低药物的生物利用率。早期的研究认为是柚汁中的富含成分黄酮类、柚甙在起这种作用，但进一步研究发现柚汁中一种含量比柚甙要少得多的呋喃香豆素衍生物才是与CYP3A4发生作用的主要活性成分，这些呋喃香豆素衍生物通过选择性抑制CYP3A4酶的活性，减少了药物成分在肠道内的分解，导致药物以通常数倍乃至十几倍的量进入血液，从而提高人体对药物的吸收水平，延长药物的使用周期，提高药物疗效。但是，并非药物的生物利用率越高越好，过高反而增加其毒副作用;而有些价格昂贵的特效药物，又往往需要提高其生物利用率，以降低服药成本。</p>
西柚汁的影响可能是第一个有记载的，但苹果和橙汁也对抗肿瘤化疗药依托泊苷 有作用，苹果和橙汁也对β-受体阻滞药类高血压药有作用，苹果和橙汁还对环孢霉素的作用产生影响，环孢霉素是用于器官移植病人以防止对移植器官的抗拒的。有些柑桔型碳酸饮料中含有的西柚汁多到足够引起病人服用药物，非凡是环孢霉素时的相互作用。</p>
不像其他水果，西柚含有大量柚皮苷，柚皮苷对CYP3A4酶的影响要在较长时间以后才能被观察到，最长可达72小时。更成为问题的是只要4盎司的西柚就含有足够的柚皮苷来抑制CYP3A4酶作用物。</p>
随着研究的进展，受西柚影响的药物的名单还在不断增加中，西柚汁会影响那些药物的生物利用率?这种影响是有利的还是不利的?影响程度如何?如何根据进食西柚来调整服药量?这些知识超出了本文讨论的范围，也不是一般病家所能搞清楚的。建议你假如在服药的同时也打算吃西柚的话，一定要首先向医生和药物专家咨询，以避免出现意料之外的后果。假如无法评估西柚对于你正在服用的药物有什么影响，最好的办法是停止食用西柚。</p>
