The U.S. market for anti-aging products -- estimated at about $80 billion -- is expected to climb to more than $114 billion by 2015. But perhaps midlifers who have that "forever young" mindset should save their money. Experts say you can eat your way to a younger, healthier you. In general, you should replace fattening starches with whole grains and cover at least half your plate with fruits and vegetables.
Here are seven foods that experts say could make you look and feel 10 years younger. What do you think? Let us know in comments.
Even just one orange a day can help you feel younger. Not only is this delicious fruit packed with vitamin C, but it also boasts skin-firming collagen.
Just a half-cup of broccoli a day can make you feel energized while also boosting your immune system. Why? Because broccoli contains more than 2/3 of the daily recommended dose of vitamin C. Broccoli also has the nutrient sulforaphane, which helps with liver detoxification, and has properties that help fight cancer.
3) Low-fat yogurt
Low-fat yogurt has a variety of health benefits. It provides the calcium and phosphorus that can boost tooth enamel, which will make your smile even brighter. In addition, yogurt consumption appears to help reduce skin wrinkling.
4) Bell peppers
Bell peppers are chock-full of antioxidants, especially the brightly colored red, yellow and orange ones. Indeed, these peppers can boost immune function, ward off sun damage and even reduce your risk of several types of cancer.
All types of berries are good for you -- cranberries, strawberries, blackberries, blueberries, raspberries -- but the darker ones are the best as they usually have the highest concentration of antioxidants. Berries also have a lot of vitamin C, which is good for your skin.
6) Sweet potatoes
Sweet potatoes offer an abundance of benefits, everything from antioxidants to anti-inflammatory agents. They also have vitamins A, C and E, which can help you maintain a lovely complexion and beautiful hair.
Carrots pack a lot of beta-carotene, which not only helps with skin-cell renewal, but acts as a powerful antioxidant. Antioxidants are great for getting rid of free radicals that can make your skin age faster.

Do Not Eat: Fried Food
Fried food is loaded with fat and calories while offering zero nutritional value. It's a lose-lose! Sure, fries and chips TASTE good, but healthier items also taste good. Just say no to the deep fried items on your menu. You'll be thinner, healthier and won't have greasy fingers.
Try This Instead: Broiled
If you simply must have a French fry, then make them at home in your oven. Use sweet potatoes, as these are a more complex carbohydrate. Cut into matchsticks, drizzle with a tablespoon of olive oil along with a dash of salt, then place in your oven on broil. Turn every five minutes until the fries are tender on the inside and crispy on the outside.
Do Not Eat: White Bread
White bread products have minimal nutritional value and are quickly converted by your body into sugar. So you may as well eat a cupcake. Even breads that are technically wheat, but are as soft and smooth as white bread, should be avoided. Don't be afraid to discard the bread from your sandwich or to push away that bread basket. Your waist will shrink and you'll lose that bloated feeling that high carbohydrate meals give you.
Try This Instead: Sprouted Grain Bread
If you must have bread, then stick with sprouted. Sprouted grain bread is a lot easier on your digestion and is packed full of nutrients. Two delicious brands are Food For Life's Ezekiel bread, and Manna Organics. Sprouted grain breads are often kept in the freezer section since they don't contain preservatives to prolong shelf life.
Do Not Eat: Creamy Salad Dressing
You were so good to order a salad, but then canceled out the low-cal benefits by drenching the salad in fattening creamy dressing. Just a few tablespoons of creamy dressing contain more than 20 grams of fat and hundreds of calories.
Try This Instead: Vinegar Dressing
Vinegar-based dressings pack amazing flavor in with minimal fat and calories. You can even mix your own dressing at home. Take high quality vinegar, fresh lemon juice, salt and pepper, your choice of dried herbs, and a bit of olive oil.
Do Not Eat: White Rice
Just like white bread, white rice has minimal nutritional value, and the glycemic load will quickly prime your body for storing fat.
Try This Instead: Brown Rice
Brown rice has three times the amount of fiber, more B vitamins as well as other nutrients and will keep you feeling fuller for longer. That should be enough to convince you to swap your large pile of white rice out for a small pile of brown rice.
Do Not Eat: White Sugar
Sugar and high fructose corn syrup are the epitome of anti-fitness food. Nothing will destroy your progress, expand your waist and plummet your energy levels like sugar. If you only take away one do-not-eat food from this slideshow, please let it be sugar.
Try This Instead: Fruit
Don't turn to artificial sweeteners to get your sweet fix, instead turn to nature's wholesome source of sugar: fruit. Eat organic fruit that is seasonal and locally grown. Stay away from dried fruit and fruit juices, as these are high in simple calories.
