Not everyone reacts to oat milk

According to gut researcher Martin Steen Mortensen, some people may experience discomfort from oat milk, but it doesn’t affect everyone the same way.
Fermentation in the gut can cause gas

Oat milk contains maltose and beta-glucan, which ferment in the gut. This process can lead to gas formation and bloating in some individuals.
Emulsifiers may impact gut health

Animal studies suggest emulsifiers can negatively affect gut health, but there’s no solid evidence proving the same effect in humans.
Rapeseed oil is not to blame

Experts dismiss the idea that rapeseed oil in oat milk causes bloating. Instead, they highlight its healthy fat content.

Try eliminating oat milk

If you suspect oat milk is causing digestive discomfort, experts suggest avoiding it for a while to see if symptoms improve.
Alternatives to oat milk

If oat milk doesn’t agree with you, try almond or soy milk. Lactose-free cow’s milk can also be a suitable option.
