What is the primary health concern with consuming genetically modified foods?

The primary health concern with consuming genetically modified foods revolves around the potential for these foods to cause food-related allergies. The modification processes that create genetically engineered organisms can result in the introduction of new proteins into the food supply. These novel proteins have the potential to provoke immune reactions in some individuals, leading to allergic responses.

This concern is particularly significant for those who may have existing sensitivities or allergies, as a genetically modified organism might introduce allergens that were not present in the original, non-modified food. Regulatory bodies often assess the allergenic potential of these new proteins before approval, but the possibility remains a topic of continued research and debate in the fields of nutrition and food safety.

While the other health concerns listed, such as risks of cancer, increased cholesterol levels, and hormonal imbalances, have been subjects of investigation, none have been conclusively linked to genetically modified foods to the same extent as the allergy concern. These other options may arise from different factors unrelated to genetic modification or may not have sufficient scientific evidence backing them as primary concerns.
