Eating junk food while pregnant may make your child a junk food addict

A healthy diet during pregnancy is critical to the future health of your children. New research suggests that pregnant mothers who consume junk food cause developmental changes of the opioid signaling pathway in the brains of their unborn children. Consequently, these children are less sensitive to opioids released upon consumption of foods high in fat and sugar, and need to eat more to achieve a “feel good” response.
