跟直接吃全果和蔬菜相比，榨汁并不会更健康。
在通常情况下，榨汁需要使用机器从新鲜果实或蔬菜中提取汁液。汁液中含有果实的大部分维生素、矿物质和植物素。不过，全果和蔬菜中所含有的健康纤维往往会在榨汁过程中流失。
有些人认为身体从果汁中吸收营养的效率比从全果和蔬菜中吸收营养的效率更高。但通常情况并非如此。
还有些人尝试只含新鲜果蔬榨汁的短期饮食。这些饮食方法被称为果汁排毒或禁食。其中一些饮食法可能声称有助于排除毒素、促进消化或减重。不过，其效果并没有强有力的科学证据支持。果汁排毒法不会给您足够的营养，甚至可能会带来其他健康风险。果汁排毒过程中减掉的体重，在恢复正常饮食后，可能很快会反弹。
榨汁可以促进均衡饮食。比如，榨汁可能帮助您食用您不喜欢的水果和蔬菜。
榨汁也可以减轻消化系统消化纤维的负担。对于有某些健康状况或接受某些治疗的人，榨汁可能会有所帮助。除非医疗护理专业人员建议，否则不要减少纤维摄入。纤维是保持消化道健康的关键，可以帮助您建立饱腹感。
一般来说，可以考虑用搅拌机代替榨汁机来制作果汁。将果实和蔬菜的可食用部分在一起搅拌，可以得到一杯富含植物中的健康元素和纤维的饮料。
如果您尝试榨汁，请尽可能确保制作的果汁能一次性喝完。鲜榨果汁可能很快就会滋生有害细菌。如果您购买新鲜果汁商品，请选择巴氏杀菌产品。
