4. Yoo-hoo
pH level: 6.01
We are halfway through our list of least acidic drinks for stomach ulcer patients. And at the 5th place, we have Yoo-hoo. It certainly does not need any introduction, since this chocolate drink has been in operation since the 1920s. If you love chocolate flavored drinks, then you have definitely heard of Yoo-hoo. The good news is, you do not have to stop drinking Yoo-hoo if you have a stomach ulcer. As you can see, Yoo-hoo has a pH level of 6.01. At this level of pH, it is still considered to be acidic, but to be honest, it should not make your ulcer worse.
