The trouble with sugar is that it’s everywhere—it’s in ketchup, soft drinks (even those labeled “green tea”), cereals, sweets, and salad dressings. It’s easy to consumer too much sugar and too much sugar can make you look old. Sugar in the blood can combine with proteins, such as found in the skin’s collagen, and make your normally supple skin more fragile and brittle. Too much sugar can make you fat (not your best look) and contributes to inflammation, which makes your joints ache. Overdoing sugar can also give you a headache which makes those nasty lines in your forehead even more prominent.
