NORFOLK -- Health and environmental concerns have sparked efforts to require genetically-modified foods or GMOs to be labeled.
Last week, senators rejected a provision in a farm bill to give states the power to require labels on GMOs.
Genetically-modified foods started well-intended. One example was to have cows produce more milk to be able to meet the demand of our population; however, there are serious concerns about what this may do to the human body.
"There is indication that the growth hormone that has been added to cows in order to increase their milk supply, which is a genetic modification, might lead to more cases of breast and gastro intestinal cancers, said nutritionist Shaye Arluk.
"I don't think most people realize that about 60-80 percent of the foods that they find in their grocery store every day contains genetic modification," Arluk added.
Arluk says there are three main ingredients found in genetically modified food.
"You can avoid canola oil. You can avoid corn, especially in the form of high fructose corn syrup, and you can avoid soy products."
She says if choosing between canola and olive oil, go with the latter.
"So out of these two, pick the olive oil, absolutely."
Some brands like Silk use labels that show it has a non-GMO verified product.
