Glyphosate is sprayed onto crops, which means that it can end up in our food. You're potentially eating food containing glyphosate if it isn't organic. The best way to avoid glyphosate exposure is to choose organic, high-quality crops that won't have been sprayed with chemical products during growth. Organic soil is also a lot higher in minerals, which is an advantage to both you and the environment.
If you can't afford to eat organic, try to eat locally-grown produce as much as possible, which is far less likely to have been doused in glyphosate.
