在生酮饮食中，摄入足量的钾可以帮助预防酮流感的症状，例如肌肉痉挛（以及与钾缺乏相关的其他副作用）。

钾有助于肌肉收缩，神经功能等。钾是一种重要的电解质，我们首先应该通过饮食来补充钾，而不是直接寻找钾的补充剂！

1 菠菜

菠菜是一种营养价值很高的绿叶蔬菜。一杯(约180克)煮熟的菠菜就能提供18%的RDI(recommended dietary intake推荐每日营养摄入量标准)钾。

菠菜不仅是一种生酮中可以食用的蔬菜，它还提供近4倍的维生素a RDI, 10倍的维生素K RDI。同时，菠菜等绿叶蔬菜也富含抗氧化剂。

2 牛油果

牛油果质地绵滑、多脂，味道鲜美，富含纤维、抗氧化剂、叶酸、维生素C、K和B6。

牛油果是钾的极佳来源，一个中等大小的牛油果能提供20%的RDI。

鳄梨中的营养成分可能对健康有积极的影响。鳄梨已被证明对体重管理，代谢综合症和心脏健康有益。

3 鲑鱼

鲑鱼不仅富含促进健康的omega-3脂肪和蛋白质，还富含钾。半条野生鲑鱼片(约187克)含967毫克钾，是RDI的18%。

富含脂肪的鱼的饮食对健康有很多好处，包括降低患心脏病的风险。

4 西红柿

很多人都喜欢的西红柿也富含了钾，西红柿还含有维生素E，B6，A和C，以及铜。

还含有番茄红素等植物化合物，可能有助于减少炎症和前列腺癌的风险。

5 蛤蜊

仅100克的蛤蜊就能提供18%的RDI钾。蛤蜊还富含其他营养素，如硒、铁和维生素B12。

蛤蜊还富含蛋白质和健康的omega-3脂肪。这些美味的小贝类对你的健康也有好处，蛤蜊可以减少炎症和相关疾病。
