Sarah Berry:坚果富含脂肪,但对健康有益,这与人们的普遍认知相反。坚果富含多种营养物质,包括纤维、维生素E、镁和硒等。坚果有助于降低坏胆固醇和甘油三酯水平,从而降低患心脏病和中风的风险。坚果中的生物活性物质,例如多酚,具有抗氧化和抗炎作用,可以保护细胞免受自由基损伤,并降低氧化型LDL胆固醇的水平。研究表明,食用坚果可以降低炎症标志物水平,改善胰岛素敏感性、降低空腹血糖,并改善血管功能。一项研究表明,食用杏仁可以改善血管功能。初步研究表明,坚果可能有助于预防老年痴呆。坚果富含膳食纤维,有助于降低多种慢性疾病的风险,甚至可以延长寿命。完整的坚果中的脂肪不易被消化吸收,因此实际吸收的卡路里比标签上标注的要少。不同个体从相同数量的坚果中吸收的卡路里差异很大。研究表明,坚果不会导致体重增加。建议将坚果作为零食,并食用多种类型的坚果。 Jonathan Wolf:英国人每天坚果摄入量平均仅6克,远低于推荐量。人们担心坚果热量高会引起体重增加。与其他高纤维食物相比,坚果的卡路里吸收率更低。加工处理后的坚果更容易被消化吸收,卡路里吸收率更高。食用完整的坚果,维生素E等其他营养物质的吸收率可能会降低。总结坚果对健康有益。

Shownotes Transcript

In today’s short episode of ZOE Science & Nutrition, Jonathan and Sarah ask: If nuts are so full of fat, can they really be good for us?

There is no shortage of variety when it comes to the mighty (yet humble) nut and the ways we consume them. Dried, chopped, made into butter or roasted (over an open fire, anyone?) these little guys provide the nutrients our brains and bodies need in surprisingly high quantities. From industrially farmed to indigenously hand-harvested, the story of these nuts is, well…nuts!
