Week 13: Free Radicals and Antioxidants

Do we rely too heavily on supplements to provide antioxidants?

In my opinion, yes. Many people would rather pop a pill than eat some plants. Also many of the plants that are eaten are not the most nutritious like iceberg lettuce or white potatoes, or they are grown in a way that depletes their nutrition such as with the use of pesticides and chemical fertilizers. Supplements are generally trying to be as nutritious as a plant but I would argue that it is impossible to do since we still don't know how the thousands of different vitamins, antioxidants and other phytochemicals interact with each other within the plant, not to mention the fiber, plant sugars and naturally distilled water found in plants.

How might we deal differently with the effects of environmental pollutants?

I think the better plan would be to not worry so much about the effects, and try to do something about the source. We don't really know how to deal with toxic chemicals once they are out in the world, but if we could stop making them in the first place, I think that would be a good plan. Of course, it would mean that we would have to stop producing things that create toxic chemicals as a waste product. And that's almost everything, including the computer I am writing this blog on right now...

Class discussion: hands free faucet = gross!

It was in one way insanely shocking to learn about how the hands free faucets harbored more germs than the traditional faucet, and at the same time, I was not surprised at all. It reminds me of all the things we do to try to defeat nature that blow up in our faces. It was brought up in class that we act like we are separate from nature by trying to eliminate germs and dirt and trees. We always seem to find out in the end that all of those things were maintaining a balance necessary for us to thrive. No matter how much we fight it, we are still human-animals that live as a part of our ecosystem just like the trees, squirrels and germs.
