Switch to eating more and more organic and grass-fed meats and wild-caught fish and seafood. Conventionally raised animals are usually fed GMO Corn and GMO soy-based diets and farm-raised fish are often fed GMO feed, too. Organic and grass-fed meat and wild-caught fish are the way our sources of animal protein were until 60 to 70 years ago or so. Find local grass-fed meats at your local farmer’s market. You can also purchase organic grass-fed meat and wild-caught fish at good sale prices periodically at natural food stores.
