In a post on Reddit on Tuesday, user u/Alone_Country8300 explained that he had argued with his wife over his mom’s eating habits.

Studies trying to pin down how common picky eating is have come back with varying results, with some suggesting just 6 percent of people can be classed as “fussy” when it comes to food, while others say the number is more like 50 percent of the population.

Signe Svanfeldt, lead nutritionist at healthy eating app Lifesum, told Newsweek: “Fussy eating can happen in different life stages. Typically, fussy eating only lasts in children or adolescents, but it could last a lifetime. Some people might just have an aversion to one specific food, while others might be very picky and only have a handful of options they consider eating.”

Whether these eating habits can cause issues or not depends on the number of foods that are being excluded, says Svanfeldt: “If there are just a few food items that you prefer not eating, it’s most likely not something to worry about—as long as the diet you have is varied and balanced, and provides you with enough energy, then you are likely getting enough nutrients. If, however, a lot of food groups are excluded from the diet, it can be challenging to get enough nutrients in the, which can lead to nutrient deficiencies.”

On Reddit, the man explained that he didn’t feel his mom’s food preferences were that bad and wrote: “My mom is not a picky eater. She will eat almost anything unless it has ketchup on or in it. Also growing up I was never made to eat anything—my body, my choice, and she would make me a second meal.”

While he admitted that he wasn’t sure his wife knew about the ketchup thing, the pair have a fractured relationship as it is.

“The two of them cannot stand each other, so I have greatly cut back on how often I see my mom,” said the Redditor. “But recently she was invited over to meet our daughter and my wife asked if she wanted to stay for dinner.”

His mom agreed to stay, but when she realized they were having meatloaf with a ketchup topping, she only took some potatoes and zucchini.

When the man’s mom sat down to eat her food, his wife was not impressed. “My wife blew up and demanded she take the meatloaf. My mom said if she put any on her plate she would throw it,” wrote the Redditor. “I told them both firmly to stop and my wife demanded I defend her. I told her to just leave my mom alone and let her eat what she wants.”

Left in the middle, the man explained how his wife yelled at him to defend her while his mom walked out of the house.

“My wife did not speak to me for the rest of the night,” he said. “The way I see it, everyone should be able to turn down food for any reason, and everyone is entitled to some foods they absolutely will not eat.”

Online though, Reddit users overwhelmingly backed the man for siding with his mom. One commenter wrote: “That’s a big red flag on your wife’s part. She’s not respecting your mom’s personal boundaries, choices, and autonomy.”

Another Redditor said: “Your wife is unhinged. I’m sorry she’s treating your mother this way. She’s going to do this to your children too. You know that, right? Better get this figured out now.”

“Food preferences are a very sensitive and personal topic, and it can be triggering to have others intruding on one’s way of eating. You can, however, support your friends and family by encouraging them to widen their eating habits,” said Svanfeldt who encourages taking steps like having a relaxed discussion about it, encouraging people to take small bites of a food item—but respecting if they don’t want to.

She also suggests speaking to friends and family before inviting them for a meal, asking them what foods they like and dislike, and deciding on what to cook together.

“As long as the preferences aren’t causing any harm to your body (i.e. having a too restricted diet), the people around you simply have to respect the way you choose to eat,” said Svanfeldt.
