Non-GMO grocery shopping guide

Studies have shown that genetically modified (GM) vegetables can cause cancer in laboratory rats. GM corn is also linked to lab-rat organ failure. Best to avoid GMOs (genetically modified organisms), say some folks. Non-GMOShoppingGuide.com offers these shopping tips:

• Buy products labeled “organic.” Certified-organic products are not allowed to intentionally include any GM ingredients.

• To be “doubly sure,” the site says, look for products that bear the “Non-GMO Project Verified” seal.

• Buy dairy products stating that they have no rBGH (recombinant bovine growth hormone) or rBST (recombinant bovine somatotropin), or are labeled “artificial hormone-free.”

• If unsure, avoid products made with any of the eight GMO food crops, which include corn, soybeans, canola, cottonseed and sugar beets. In the case of nonorganic sugar, if it is made in North America, “it is almost certainly a combination of sugar from both sugar cane and GM sugar beets.”
