Here's a little fact that many people aren't aware of. There is an ingredient on you can of soda that has a contributing factor in your weight gain.
If you look on the ingredient label on your can of Coke, you will notice that it contains almost 50 mg of sodium. Now, that amount of sodium is well below the daily recommended limit of no more than 2,300 mg per day.
However, salt alone isn't the only part of this story. Coke also contains caffeine. In addition to it's characteristics as a stimulant, it is also a diuretic. That means that is causes you to pass free water from your body. That's why nutritionists recommend that you drink water, not colas, coffee, or tea. Too much of these items without other sources of liquids could lead to dehydration.
So, what happens when you decrease the free water in your system and then add salt? You get thirsty.
The result of this is that you will drink more soda. It's a vicious cycle. The more you drink, the more thirsty you feel, which causes you to drink more, which makes you more thirsty.
Now, that's bad enough, but the real health danger is what else is in your can of Coke, high fructose corn syrup (HFCS). HFCS causes a number of health risk, besides pushing the calorie count up.
Those extra calories result in more weight gain, and an increase in dense-LDL, which is directly related to heart disease.
As always, your best bet for healthy eating is to choose water as your beverage of choice. It has zero calories, not dangreaous side effects, and it's something your body needs to function properly.
It's all about making better food choices.
