<div><p>There has been a lot of speculation as to what is causing the obesity epidemic in today's youth. </p><p>Of course, the obvious junk food is a key factor, the lack of exercise too. But one researcher at the University of Leeds, Professor Benton, says there's a <a href="http://www.bbc.com/news/business-39254804">link </a>between global trade and the obesity rate and it all centers around one thing. </p><p>That thing? Oil. </p><p>Professor Benton says recent trade agreements have made it easier to export and import types of cooking oils, which then makes them more common in the foods we eat. These oils are contributing factors to our collective weight problem. </p><p>"The poorest anywhere still struggle to get sufficient calories and are underweight, but in our rich countries, poverty often does not stop people being able to eat (and drink) calories, but it does stop them having a nutrient-rich diet," <a href="http://www.bbc.com/news/business-39254804">says </a>Professor Benton. </p><div><figure><amp-img src="https://www.shared.com/content/images/2017/03/fries.jpg" srcset="https://www.shared.com/content/images/2017/03/fries_GH_content_550px.jpg 550w, https://www.shared.com/content/images/2017/03/fries_GH_content_650px.jpg 650w, https://www.shared.com/content/images/2017/03/fries_GH_content_750px.jpg 750w, https://www.shared.com/content/images/2017/03/fries_GH_content_850px.jpg 850w, https://www.shared.com/content/images/2017/03/fries_GH_content_950px.jpg 950w" sizes="89vw" title="" alt="" height="9" width="16" layout="responsive"></amp-img><figcaption class="op-vertical-center"><cite>Team Better</cite></figcaption></figure></div><p><!-- [invalid-shortcode] --></p><p>Professor Corinna Hawkes, director of the Center for Food Policy at University of London, agrees with Professor Benton's theory. </p><p>"Because it became much easier and cheaper for the processed food industry to import it there was no disincentive for using it," she <a href="http://www.bbc.com/news/business-39254804">says</a>.</p><p>Professor Hawkes also notes, however, that trade in fruits and vegetables has also increased, making them more readily available.

The diets we have been eating are targeted towards active, moving people. If we started to eat less in comparison to how much we move, the obesity problem would fix itself. </p><div><figure><amp-img src="https://www.shared.com/content/images/2017/03/exercise.jpg" srcset="https://www.shared.com/content/images/2017/03/exercise_GH_content_550px.jpg 550w, https://www.shared.com/content/images/2017/03/exercise_GH_content_650px.jpg 650w, https://www.shared.com/content/images/2017/03/exercise_GH_content_750px.jpg 750w, https://www.shared.com/content/images/2017/03/exercise_GH_content_850px.jpg 850w, https://www.shared.com/content/images/2017/03/exercise_GH_content_950px.jpg 950w" sizes="89vw" title="" alt="" height="9" width="16" layout="responsive"></amp-img><figcaption class="op-vertical-center"><cite>Texas Rock Gym</cite></figcaption></figure></div><p><!-- [invalid-shortcode] --></p><p>What do you think the leading cause of obesity is?
