You could almost use any aspect in life as an example because science is all around us. One example I recently stumbled upon was an active ingredient in many cereals that are out there today. I have always been told be careful what you eat, but Mainly I think of that as fruits and veggies over grease and processed foods. I recently bought a box of Lucky Charms cereal, one of my child hood favorites. I noticed that the second ingredient on the nutrition list was sugar...and the 11th was trisodium phosphate. That one took me by surprise. Because of my science background, I knew that was some type of chemical, so I looked it up. It happens to be an active degreasing agent that is used as a paint thinner and can be found at any hardware store. Doing a little more research I realized why they put it in, it not only cuts down on the greasy taste, it also acts as an anti-molding agent to preserve the cereal.
While the FDA may approve the small amounts in the cereal, I still remain take caution when putting that in my system. Maybe in one serving size it may not be hazardous, but I never just eat one cup of cereal. And over a life time of eating it, what then? My advice to everyone is to understand that science literacy can truly prolong and better your life and the decisions you make.
