Food Matters: A guide to conscious eating – Mark Bittman.
This book focuses on how best to navigate current supermarket (& farmer market) choices so that what goes in your mouth is healthy for you and healthier for your environment.
The most interesting take-away so far:
To produce one calorie of corn takes 2.2 calories of fossil fuel. It requires 40 calories to produce one calorie of beef protein.
To give you an idea of how much more energy goes into junk food than comes out, consider that a 12-ounce can of diet soda – containing just one calorie – requires 2,200 calories to produce, about 70 percent of which is in production of the aluminum can.
Yikes! Even removing the packaging from the equation to “level the playing field” still equates to 660 calories to produce one calorie of soda.
NOTE: I didn’t get all the way through this book before it was due back to the lender, so I’ll have to sign up to get my hands on it again!
