GMO’s – Good or Bad?

I recently listened to a very interesting podcast about bananas on Freakonomics. It highlighted how modern farming techniques have made producing bananas fairly inexpensive. Bananas are one of the most popular fruits in the world. However, this plentiful fruit is at risk of extinction due to a fungus. This risk is partly due to our production efficiencies that make it so affordable.

The podcast highlighted something I hadn’t thought of before. You go to the grocery store. How many kinds of apples are there? Probably at least half a dozen. How many kinds of bananas? One. The whole world (for the most part) consumes one variety of banana. However, this variety is threatened by a fungus that could literally wipe out all the banana plantations. For THIS variety of banana.

Interestingly, some scientists have found a solution. They have successfully modified the DNA of some banana plants to be resistant to this fungus. The scientists have put one gene from a wild banana plant into the current banana plant used and found that it is immune. One gene. Brilliant, right? Except, this hasn’t taken on like wildfire because of the widespread concern over GMO’s in our food.

Now, I’m not telling you that you have to be for or against GMO’s. I think everyone is entitled to an EDUCATED opinion. But I would strongly encourage you to learn more about what we actually do and do not know about GMO’s related to our food supply.

It reminds me of a speech I heard from a food scientist years ago. He talked about how as healthcare professionals we (often) tell people to stay away from food additives. But then we complain about the cost of fresh foods and it being unavailable for all people. He pointed out you can’t have it both ways. The scientists came up with the additives to lower the cost of food and increase availability.

I just think it is important to understand both sides. You don’t want GMO bananas? That’s fine. But don’t complain when they are basically non existent or very expensive in a few years.

For the record, I don’t have a firm opinion on GMO’s. I think there is a lot of information out there, good and bad. And a lot we don’t know yet. I just post here to remind us that when we form one opinion, we have to accept the ramifications.
