Here’s Why Women Should Avoid Fried Food Before Pregnancy

2 minute read

So much for those burger-and-fries cravings.

A new study published in Diabetologia found that women who eat more fried food before conceiving are at greater risk for developing gestational diabetes—the kind that starts or is first noticed during pregnancy. Researchers looked at diet questionnaires from about 15,000 women enrolled in the Nurses’ Health Study II.

Once they adjusted for BMI, researchers found that women who ate fried food seven or more times a week had an 88% greater risk for gestational diabetes than those who ate fried food less than once a week.

Interestingly, the association was particularly strong with fried foods eaten away from home compared to home-cooked fried food. Restaurants tend to reuse their oil for multiple fryings, a practice that deteriorates oils through oxidation and hydrogenation. “Refrying may produce more of those detrimental chemicals,” says co-author Cuilin Zhang, MD, an investigator at the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Frying also creates inflammatory compounds that may contribute to cell damage and diabetes—which Zhang suspects are related to the fried food.

No one would argue that a chicken nugget is a health food, but that kind of dining may be more hazardous when you’re getting ready to eat for two.

Answer: A 1/2 cup of ice cream
Answer: A half cup of ice cream If you eat what you’re craving, you’re more likely to feel satisfied and eat less. And scoop for scoop sorbet contains twice the sugar with none of the filling dairy protein and fat.Getty Images (5); Gif by Mia Tramz for TIME

Answer: Butter
Answer: Butter Serving size for spray butters (even low-calorie ones) are around a 1/3 second spray. What on earth does that mean? You're better off using a small amount of real butter as opposed to guessing how much you're using of the mystery melange of up to 20 ingredients.Getty Images (1); Gif by Mia Tramz for TIME
Which is better for you: A sirloin burger or a turkey burger?

Answer: Sirloin burger Restaurant turkey burgers are often made with dark meat and the skin, so they’re not necessarily better for you (and for the record, they aren't low-fat). You can get a sirloin burger that’s 95% lean meat and gives you 20 g of protein. Just be careful with the toppings.Getty Images (1); Gif by Mia Tramz for TIME

Answer: Eggs
Answer: Eggs In the morning, you want a meal that will fill you up. Eggs offer protein and fat for satiety, but Special K cereal really only offers carbs and, well, air. If you want carbs to kick off the day, you're better off pairing eggs with a slice of 100% whole grain toast. Getty Images (1); Gif by Mia Tramz for TIME
