Genetically modified (GM) foods have attracted a great deal of controversy. While some consumers and organizations regard GM foods as safe, many other consumers and organizations remain concerned about their potential health risks. The results of three studies suggest that consumers respond differently to persuasive messages regarding GM foods on the basis of their preexisting attitudes. Weak anti-GM consumers tend to comply with a variety of pro-GM messages. In contrast, strong anti-GM consumers exhibit message-opposing behavior. Moreover, they respond just as negatively to a safety message (claiming that GM foods are safe) as to a risk message (claiming that GM foods are unsafe). The mechanism underlying these effects is consumers’ perceived health risk. A benefit message claiming that GM foods are beneficial (e.g., more nutritious than their conventional counterparts) is a better alternative for strong anti-GM consumers. Finally, the results suggest that persuasive messages do not significantly change pro-GM consumers’ evaluations of these foods.

Background: The use of genetically modified foods and organisms has continued to gain popularity globally, especially in the areas of improved food security and medical research. However, the global acceptance and consumption of these foods are marred by skepticism and controversy due to concerns about their long term health and environmental effects. This study was undertaken to assess the knowledge and perception of genetically modified foods among medical doctors of the Jos University Teaching Hospital in Nigeria.Methods: A cross-sectional study was conducted in May 2018 among 230 medical doctors who were selected using a stratified sampling technique. Data were collected using a semi-structured self-administered questionnaire and analyzed using the Statistical Package for Social Sciences version 23. Results: Only 19.5% of the 230 respondents were found to have good knowledge of genetically modified foods, while 87% expressed concerns related to possible health risks from the consumption of these foods. A low proportion (31.7%) of the respondents indicated willingness to consume genetically modified foods.Conclusion: There was a low level of knowledge of genetically modified foods, heightened concerns about possible adverse health risks associated with their consumption and a low willingness to consume such foods among medical doctors in the Jos University Teaching Hospital. Therefore, there is the need to further educate doctors on the benefits and safety of genetically modified foods.

When it comes to experimentation, informed consent must be given. How will North Americans feel when they find out they have been unknowingly participating in the consumption ofgenetically modified (GM) foods? GM foods develop global controversies, and have since their introduction into the international food market. Top stories in the news today cover the concerns of GM products facing the environment and its biodiversity; however, they seem to neglect the health risks for humans. This is because most GM food providers do not want possible health risks to get in the way of profit. Therefore, the vault must be opened: Genetically modified foods need to be avoided because of the detrimental health risks associated with their consumption. The health risks regarding genetically modified foods are extremely important because they can be easily prevented if the globe comes together to promote a natural world. It will undoubtedly be difficult because of the invasion of GMOs that has already taken place, but refusing to purchase GM products, at least until they are proven to be safe, is an ideal place to start.
