Why Do Beyond Burgers Give Me An Upset Stomach (Or Even Diarrhea)?

W

I’ve been seeing more and more stories of people complaining about stomach issues after having a beyond burger.

While I don’t have a definitive answer as to why, I do have a guess.

Take a look at the ingredients list (I removed the vitamins and coloring ingredients):

water, pea protein isolate, expeller-pressed canola oilrefined coconut oil, rice protein, mung bean protein, natural flavors, methylcellulose, potato starch, sunflower oil, salt, potassium chloride, apple extract, vinegar, lemon juice concentrate, sunflower lecithin

Pea protein and the other proteins are pretty unlikely to give you any stomach issues. You’ll find those in most vegan protein powders, so you can always try a few shakes if you’d like to test it.

The only ingredients I can really see causing an issue is all the oil.

Beyond Burgers Have a LOT of Fat

If you’ve ever cooked one on a frying pan, this shouldn’t be a surprise. You don’t need to add any oil yourself because quite a bit comes out.

Oil in small amounts is fine, but eating a lot of fat in a short amount of time is known to cause stomach problems (unless you’re on a diet like keto and are used to it).

The beyond burger has 40 grams of fat per burger, which is the same amount of fat as in 0.7 cups of cashews, which is quite a bit.

Even just one burger might give you stomach issues if you typically don’t eat too much fat (I really wouldn’t recommend adding any mayo to it as well).

If you only have issues after eating 2-3 beyond burgers, try limiting how much you have next time and see if you feel better.
