Until we know more, I will try to figure out what food products have the Roundup chemical in their production, and avoid such products (although it's hard to be sure).
You'll be healthier if you do, but I doubt it would have anything to do with the glyphosate.
Pretty much all the soybeans and corn are grown using glyphosate. So eliminate consuming foods containing soy, or corn, including corn syrup and high fructose corn syrup. Eliminate consuming meats of animals which have been fed corn. Probably leaves you eating wild-caught fish as a readily-available meat source if you want to completely avoid foods produced with glyphosate, I suppose.
It isn't the glyphosate that is actually the problem in what you eat. It's the corn and soybeans themselves. High in carbohydrates/low in nutrients. Although it isn't produced using glyphosate as far as I know, wheat is just as bad, if not worse in harmful health effects as a high carb/low nutrient source of calories. You might as well try staying healthy living on spoonfuls of refined sugar.
