NEW YORK (CBSNewYork) — From vegans and vegetarians to those who go gluten free and paleo, there’s no shortage of incompatible eating habits.

As CBS2’s Cindy Hsu reported, these dietary differences are causing heartburn for couples in and out of the kitchen.

“When I was buying milk he’d say, ‘Why do you have to buy almond milk, can’t we drink regular milk?” Grace Farren explained.

“He found out that I was a vegan and he refused to call me, to even explore who I was as a person,” Benay said.

“One thing I say is just lighten up,” Slayton suggested.

Slayton said you can find common ground, especially over ingredients.

That’s worked for meat eater Jennifer Chiminiello and her vegan husband of 13 years, Robert.

“We have some recipes that are amazing,” they explained.
