Sophie Medlin: 肠道与大脑之间存在持续的双向沟通。肠道菌群的健康状况直接影响大脑功能,包括血清素的产生、神经信号的传递以及压力激素皮质醇的分泌。不健康的肠道菌群可能导致血清素不足,影响情绪和认知功能,例如注意力、精力和睡眠质量。此外,肠道菌群会影响下丘脑的活动,进而调节皮质醇的水平。忙碌的生活方式和不健康的饮食习惯(例如饮食单一、缺乏植物性食物)都会损害肠道健康,加剧这些问题。为了优化肠道健康,建议每周摄入至少30种不同的植物,以提供肠道菌群所需的丰富营养。 研究表明,特定益生菌菌株可以增加血清素的产生,改善焦虑和抑郁症状。一些营养素,如ω-3脂肪酸和B族维生素,也具有类似的功效。甚至有研究表明,某些益生菌菌株在改善焦虑和抑郁方面与抗焦虑、抗抑郁药物一样有效。 动物实验表明,肠道微生物组的变化会显著影响行为和精神状态。虽然人类研究的复杂性限制了对自闭症谱系障碍等疾病的直接研究,但已有证据表明肠道微生物组对人类心理健康和认知功能有重要影响。 Ali: 与Sophie Medlin的讨论中,Ali表达了对肠道健康与认知功能之间关系的兴趣,并就相关研究和益生菌的作用提出了问题,体现了对该领域的关注和求知欲。
