Now Round Up is being used on non GMO crops like oats and wheat to make harvesting easier on the machines they spray the crops to kill them before harvest...also beans.
How does round up work? It kills life. The active ingredient in Round Up is a form of Oxalates, which is a poison found in many plants.
Spinach, almonds, beets, sweet potatoes, most nuts, grains and seeds are pretty high in oxalates.
Trying to be healthy? That green smoothie made with spinach and almond milk can backfire over time. Nut milks and butters, juiced fruits and vegetables can damage the gut biome over time and that leaky gut allows those toxic oxalates into the blood stream to cause inflammation all over the body when the oxalates lodge in the joints and tissues.
Oxalates form glass like shards when they bind to minerals in the diet making them unavailable and they steal needed sulfur.
Oxalates cause most kidney stones.
Autistic children known for their gut troubles do very well on a low oxalate diet.
Oxalates contribute to most chronic illness and most have no idea what they are or how they work, including most doctors.
They accumulate over time and dumping can happen once they are removed from the diet.
Might be the single biggest thing you can do for your health, learn more about oxalates.
Some good info here in a way that is easy for most to understand this issue.
