1) Diet Coke is healthier than Coke. (Sorry to any Yankees - I'm from the South. Everything's a Coke, even if it's a Mountain Dew.)
So it is true that Diet Coke has about 120 less calories than Coke. But what is exactly healthy about artificially colored, flavored, and sweetened carbonated water? Nothing. You're better off to drink something else.
2. Juice has less fat than milk, so you should drink more juice than milk.
Did you know that a glass of juice contains more calories than a glass of 1% milk? Well, it's true. Juice is composed of mainly sugar and some vitamins, while milk contains protein, calcium, potassium, and Vitamin D. So as long as you are not indulging in the full fat version, stick to the moo juice.
3. Bottled water is better for you than tap water.
Hate to break it to you, but they're basically the same thing, except tap water contains more fluoride, which is healthier for your mouth. Drinking occassional bottled water is not bad for you, but it will damage your wallet quickly. (If you insist on sticking to bottled water, make sure you buy a brand that contains fluoride.)
4. The main beverage that you should stay away from is coffee.
In general, there is no harm to your health if you drink coffee in small to moderate amounts. Now, doctors are saying that small amounts of caffiene can actually boost your metabolism and may aid in weight loss. Just remember that as always, MODERATION is the key. In fact, coffee contains less caffiene than most soft drinks. In addition to limiting your coffee cups, go easy on the cream and sugar. Use skim milk and a natural sweetener such as stevia instead.
The Bottom Line...
If you trade one calorie-laden beverage for water every day, you may drop as many as 15 pounds over a year. So guzzle that water! Also, get yourself in the habit of checking the Nutrition Facts before you drink something. Remember that ALL calories count - no matter whether you eat them or drink them!
