提起核桃，不少人还能回忆起小时侯，每当考试前吃核桃“补脑”的情景。其实，小小的核桃不但能健脑、美容，最新研究还发现，常吃核桃可以降低人体胆固醇，保护心血管。
1、减少患乳腺癌的风险
大学医学院的试验显示，实验鼠每天食用2盎司约60g的核桃，比不食用的老鼠，患乳腺癌和肿瘤的几率要小。
2、减少患抑郁症几率
核桃中富含丰富的ω-3脂肪酸，可以减少患抑郁症、注意力缺失多动症(ADHD)、癌症和老年痴呆症等的几率。
3、降低患糖尿病的风险
一项研究显示，每周坚持食用5次坚果的女性患2型糖尿病的风险减少近30%。坚果中的不饱和脂肪有益于胰岛素分解。
4、含抗氧化剂促进心脏健康
一项新研究显示，核桃中含有的高质量抗氧化剂，能很好的保护心脏机能健康，预防心脏功能疾病。
5、减除压力
去年一篇研究表明，核桃中的核桃油具有减除血液静压的作用，饮食习惯的改变能更好的帮助我们的身体应对外界压力。
一项最新实验证明，每天坚持吃核桃可以降低人体胆固醇。中华中医药学会络病分会委员、北京中医医院心血管科主任刘红旭说，核桃主要富含脂肪，其所含脂类有亚油酸甘油脂、亚麻酸及油酸甘油脂，对减少胆固醇在血中升高有益，对动脉硬化、心脑血管病患者的保健很有帮助。
中医自古就把核桃称为“长寿果”，认为核桃能补肾健脑，补中益气，润肌肤、乌须发。北京中医药大学养生室教授张湖德说，核桃最适合脑力工作者，尤其是白领女性吃，因为这部分人往往用脑过度，很耗伤心血，常吃核桃能够补脑，改善脑循环，增强脑力。同时还有乌发、使皮肤光润的作用，因为“发者血之余”，血旺则发黑，而且核桃中富含多种维生素，可以提高人体皮肤的生理活性，所以对女性而言是美容佳品。据说著名的京剧表演艺术家梅兰芳生前每天都吃核桃粥，因而皮肤舒展细嫩，面色光润。
我们把核桃的硬壳打开后，会发现核桃仁的形状很像人的大脑，很多人就是因此进一步了解核桃是能补脑的。张教授说：“这在中医学里叫做‘同类相求’或者‘以类取象’，中医本身就是一门经验科学，是根据长期的实践经验总结出的规律。事实证明，核桃确实对补脑功效非常好。”
现代营养学研究认为，核桃除去约50%的壳等废弃物后的净仁，含有63%的亚油酸、16.4%的亚麻酸，以及丰富的蛋白质、磷、钙和多种维生素，含有大量的不饱和脂肪酸，能强化脑血管弹力和促进神经细胞的活力，提高大脑的生理功能。而且，核桃含磷脂较高，可维护细胞正常代谢，增强细胞活力，防止脑细胞的衰退。在日本，有的营养学家倡导学龄儿童每天吃2～3个核桃，对那些焦燥不安、少气无力、厌恶学习和反应迟钝的孩子很有帮助。
核桃怎么吃最健康？
核桃是个宝疙瘩，可也讲究吃法和宜忌。刘主任认为，应该适量、长期、坚持服用。核桃仁所含的脂肪，虽然是有利于清除胆固醇的不饱和脂肪酸，但脂肪本身具有很高的热量，如果过多食用又不能被充分利用的话，就会被人体做为胆固醇储存起来，结果适得其反。一般来说，每天服用核桃仁的重量，应在40克左右，大约相当于四五个核桃。同时应该适当减少其它脂肪摄入，以避免热量摄入过高。张教授说，核桃火气大，含油脂多，吃多了会令人上火和恶心，正在上火、腹泻的人不宜吃。很好的一种吃法是把核桃仁和红枣、大米一起熬成核桃粥喝，因为核桃可以补“先天之本”，大米、红枣可以补“后天之本”，这样搭配起来，保健效果最佳。
Mention of walnut, many people can remember when I was a child, when eating walnuts \"brain\" before the exam.
