Think you could stomach some sweet, summer strawberries injected with fish genes?

Would you take medication made from rice injected with human genes?

No, I thought not.

How do you feel about goats producing spider-web-like milk stronger than Kevlar? Or engineered salmon that continue to grow larger? It’s about as far from natural as you can get.

Well, that’s exactly what Genetically Modified (GM) foods are – unnatural hybrids, made by adding genes from one species into another, entirely unrelated, species.

Scarily, genetically modified food is everywhere. According to the National Geographic, over 60% of food in US supermarkets directly or indirectly contain GM ingredients. Other sources say that figure is closer to 80%.

And many people don’t even realize how widespread this freak food is. We have US labeling laws to thank for this because they don’t require GM ingredients to be highlighted.

Even though they have only been around since 1994, GM crops sure have left their mark. Theythreaten our ecosystems, contaminate organic farm produce, and have been shown to cause harm to humans and animals.

Unfortunately, until laws are changed, the best option is to avoid or strictly limit your consumption of GM foods.
