Okay, so I admit that I am drastically overweight and that is mostly because I eat too much at a meal; but today I got an absolute shock. While at the convenience/gas station all these people came out with 52 ounce glasses of soda. Now given that a cola has about 100 calories per 8 ounces, which means that these people are drinking about 650 calories per glass. For a woman who is moderately active, 2000 calories is probably the maximum number of daily calories she should consume. So that drink is about 30% of a woman's calorie needs.
Perhaps the most startling was the little girl (probably 5-6 years old) and her sister who each came out with a 52 ounce drink and a snack. Assuming that the pop was not diet pop, that means they were getting about 45% of their daily calorie needs in the beverage alone.
Like I said, I am really overweight but even I have to wonder at the beverage consumption habits of the US population. Now I know that those drinks were on sale for 79 cents, but just because it is on sale does not mean we need to buy it.
