Don't Eat THIS Food In Excess, From Lisa Drayer (VIDEO)

We all know that sugar contributes excess calories, which causes weight gain, and is associated with diseases like diabetes. But according to Lisa Drayer, MA, RD, author of The Beauty Diet says that sugar can also lead to to wrinkles and acne. Make sure you're aware of how much sugar you're eating each day. Sugar is found in foods that you wouldn't think of as being "sweet," like tomato sauce, ketchup, and salad dressing. Have no more than 6 teaspoons of sugar (around 100 calories) each day, and be sure to check the labels on the foods you're consuming to see how much sugar they contain.
