Wow! Like mothers don’t suffer enough guilt.

Now a new study says that if you eat junk food during pregnancy or while you’re breastfeeding, you could cause your child to become obese.

Researchers from the Royal Veterinary College, London, say that pregnant and breastfeeding women shouldn’t eat fatty, salty and sugary foods under the mistaken belief that they’re eating for two.

As published in the British Journal of Nutrition, the study involved rats which ate a diet of processed junk food like muffins, biscuits, doughnuts, crisps and sweets during pregnancy and lactation vs. rats which ate regular feed.

The rats with the junk food diet gave birth to little rats which overate and preferred foods rich in sugar, salt and fat when compared to the offspring of the rats on a regular diet.

The scientists believe these results may apply to humans, too.

They suggest that eating a lot of junk food when you’re pregnant and breastfeeding could cause your children to overeat and develop a taste for junk food.

This could contribute to childhood obesity and make it even harder to teach kids to eat healthier foods.
