Replace "Health Benefits" with "Nutritional Benefits" and it's ok. You certainly won't starve eating non-organic food. And you'll get pretty much the same level of basic nutritional elements (vitamins etc.).
But you will get more pesticide contamination, more genetically modified food, more additives and a few other nasty bits and pieces. And you will create more impact on the environment.
And keep in mind that this was a meta-study, just looking at existing publications. Their selection criteria pretty much guaranteed the domination of conventional food studies carried out by the industry.
No need to expand anything. People just need to eat less meat. There's a conversion factor of around 8 to 15 converting plant-based food into any kind of meat. You loose around 90% of your nutrional energy by that conversion. We could easily feed the world if the industrial nations wouldn't insist on their daily hamburgers and steaks.
