Maternal diet sets up junk food addiction in babies
Date:4/30/2013

Research from the University of Adelaide suggests that mothers who eat junk food while pregnant have already programmed their babies to be addicted to a high fat, high sugar diet by the time they are weaned.

In laboratory studies, the researchers found that a junk food diet during pregnancy and lactation desensitised the normal reward system fuelled by these highly palatable foods.

Led by Dr Bev Mhlhusler, Postdoctoral Fellow in the University's FOODplus Research Centre, this is the first study to show the effects of maternal junk food consumption at such an early stage in the offspring's life. The study was published recently in The FASEB Journal.

Opioids are produced by the body as a reward response, including in response to fat and sugar. These opioids stimulate the production of the "feel good" hormone dopamine, which produces a good feeling.

"We found that the opioid signalling pathway (the reward pathway) in these offspring was less sensitive than those whose mothers were eating a standard diet," Dr Mhlhusler says.

This means that children being born to a mother who ate a diet dominated by junk food would need to eat more fat and sugar to get the same good feeling, increasing their preference for junk food. It would also encourage them to overeat.

"In the same way that someone addicted to opioid drugs has to consume more of the drug over time to achieve the same 'high', continually producing excess opioids by eating too much junk food results in the need to consume more foods full of fat and sugar to get the same pleasurable sensation," says Dr Mhlhusler.

"Mothers eating a lot of junk food while pregnant are setting up their children to be addicted.

"Although our research shows that many of the long-term health problems associated with maternal junk food diets can be avoided if offspring carefully follow a healthy diet after weaning, they are always going to have a predisposition for overconsumption of junk food and obesity. It's going to make it much more difficult for them to maintain a healthy body weight."

Dr Mhlhusler says it is important to try and understand the effects of the maternal diet at a very early stage in the offspring to see what systems could be targeted, if any, to reverse the problem.

Initial findings from further work, however, have suggested the alterations to the opioid receptors are permanent.

"The take-home message for women is that eating large amounts of junk food during pregnancy and while breastfeeding will have long-term consequences for their child's preference for these foods, which will ultimately have negative effects on their health," Dr Mhlhusler says.
