I'm not a big fan of sour foods. What's your opinion on the benefits of eating sour foods?

I think it depends what kind of sour food you're talking about. For example, lemonade is delicious and refreshing, but if you drink too much of it, it can cause stomach upset. On the other hand, kombucha is a fermented tea that contains probiotics and antioxidants, which are good for health.
