GM, or genetically modified, or GMO (genetically modified organism) means that the organism has had their genetic material altered or changed. DNA molecules from different sources are combined in vitro into one molecule to create a new gene. This DNA is then transferred into an organism and causes the expression of modified or novel traits. (www.wikepedia .com) Long term effects of consuming GMO’s are unknown, and therefore it is best to err on the side of caution and avoid them.
