What You Eat Can Make You Smarter
I was catching up on my foodie reading today and I came across an interesting theme… research that studies the correlation between what foods are in our diet and how that affects not only our physical health but our brain capacity as well. Can what we eat really make us smarter?
As a small child, I was a big fan of fruit. I didn’t eat a lot of meat early on, but fruit was always popular with me, and still is. So of course I was interested to read more about an article that said primates who ate fruit had bigger brains. If monkeys of similar social groups developed larger brains just because they ate fruit instead of leaves, I should go to the head of the class.
In case you don’t want to read the entire article, the gist is this: searching for hard-to-find fruit over leaves that were abundant and closer to ground level meant fruit eaters were more innovative and critical thinking than their lazier leaf eating neighbours. It made perfect sense when I thought about it.
The bad news is that eating more fruit doesn’t do you or I much good as this kind of development takes evolutionary time to realize the effects. Generations of fruit-eating progeny are required before we would see results. Maybe your great great great great grandchildren would be smarter, but you’re just not getting scurvy.
There is good news, though. The other research article I read was about healthy snacks versus nibbles that had less nutritional value. Did you know that if we have to wait for our food we choose to eat more healthy? Perhaps that is the real reason fast food is mostly junk – if it took longer we would be eating a salad. The researchers called it a time tax on less healthy food choices. They used vending machines at a university, with a 25 second delay on less healthy items and no delay on healthy ones.
Since the experiment did show a positive result, there is talk of extrapolating the concept for more food activities. One suggestion was that grocery store shoppers who chose more healthy options could be streamlined to a faster checkout than those with less healthy items in their cart.
Is this discrimination? Should we be allowed to be unhealthy if we choose? We know people don’t like taxes on “undesirable behaviour” (such as the taxes on alcohol and tobacco). Perhaps positive reinforcement is a less offensive option to encourage our society to “do the right thing”. I guess the catch is, who decides what the right thing is? Today we’re talking about being healthy. Tomorrow what will be the encouraged choice?
