好文，不过和楼主的说法一点不矛盾：

文章的作者说了草酸再好，有三类人要注意减量：

1. 吃抗生素肠功能被破坏的。

2. 肾病，痛风和风湿病的。

3. 基因病不能吃的。

觉得这第一第二类其实包括了很多人。

反过来说吧，如果你是个健康人，啥问题也没有，随便吃蔬菜水果。怎么判断自己是个健康人呢，我觉得光体检指标不够，还要加一个：面色红润。

 

There are a few situations, however, where someone might need to limit their dietary oxalate intake.

If you have recently been on antibiotics, or have a long history of taking antibiotics, your gut flora responsible for metabolizing oxalates has likely been temporarily wiped out or at least compromised. Juicing tubs of spinach when your gut microbiome doesn’t have the ability to deal with it could lead to a serious health problem.

If you have kidney disease, gout or rheumatoid arthritis.

There are also a couple of rare genetic medical conditions where individuals should avoid oxalates.
