RFK, Jr. would face a 'trifecta' of challenges in turning the tide on obesity epidemic: 'Not an easy fix'

Kennedy insists America's food supply is at fault - a culmination of seed oils, dangerous dyes, preservatives and other chemicals largely absent from foods in other developed nations. 

Fox News medical contributor Dr. Nicole Saphier said a "trifecta" of issues have fueled the crisis, and fixing it won't be so easy.

"This is not going to be an easy fix. It is much more complicated than just telling people 'eat healthier and do a little bit more exercise,'" she said.

For new mothers, she suggested, breastfeeding is a healthy option to control not only your own weight, but also to prevent weight-related problems for your child.

Beyond babyhood, families and communities should focus more on creating healthy environments for outdoor play, getting education about nutrition back in schools and promoting exercise.

"We also need to get these unhealthy foods out of our supermarkets, not necessarily by banning them, but we need to make sure that people, if we are consuming them, we either need a warning [on the package] or they need to make them healthier. Frankly, we need a more affordable, healthy option," she said.

"Obesity and overweight rates have have doubled since 1990… and it really boils down to several things: the ultra-processed foods in our diet, which, as RFK Jr. likes to point out, are not available elsewhere in the world. It's just here in the United States that we see these so much," Saphier said.
