Eat Low Glycemic Carbohydrates
The Glycemic Index (GI) measures how quickly carbohydrates in food become sugar in the blood. Foods high on the GI cause spikes in blood sugar and dips later on, which cause you to crave more sugar. Foods with a low GI rating will stabilize your cravings and blood sugar. Fresh, whole foods are best for maintaining your blood sugar. Low GI foods like green vegetables such as spinach, broccoli, and asparagus are full of antioxidants that promote healthy skin as well.
Limit Refined Sugar
Controlling sugar is the biggest trick to shedding years by just changing your diet. Knowing how they affect you and where they most often hide is key. Most processed, packaged foods contain sugars that cause a process called glycosylation. This causes the skin to become discolored and stiff over time. If a foods list of ingredients has sugar in the top 3, then avoid it. Remember that different types of sugar like dextrose, high fructose corn syrup and caramel may be listed instead of sugar, so beware.
Eat Antioxidant Rich Foods
Free radicals, or oxygen based molecules from toxins are the biggest culprit to advancing the aging process of your skin. Antioxidants can repair the damage done and help reduce wrinkles and chance for skin cancers. Some of the more powerful antioxidants can be found in the omega-3 fatty acids of fresh cold water fish like salmon and sardines. Other good sources are quercetin, found in broccoli, onions, cranberries, and apples, lycopene in tomatoes, watermelon, and pink grapefruits, and beta-carotene in carrots, sweet potatoes, pumpkins, and squash.
Water can literally plump the skin from the inside out and reduce the appearance of fine lines and wrinkles. Be sure to drink at least 8 tall glasses of water a day, more if possible. Drinking plenty of water will also help detoxify your body and flush out any excess wastes.
