I don’t think this can be blamed on vegetable oil. Over the past 30 years, the food industry has focused on maximizing profits. To increase consumption, they’ve employed the most astonishing tricks, like adding sugar to meats. We don’t even know if the increase in fast food chains over the last 30 years is proportional to the growth of the population. Then there’s GMO grain, etc… They’re feeding us garbage. That’s it.
