Foods That Keep You Healthy from Head to Toe
You Are What You Eat, So Eat Right
-- By Sarah Haan, Registered Dietitian
There are many motivations for sticking with a healthy diet. Eating more of the good stuff (and less of the junky stuff) can help you prevent cancer, extend your lifespan, protect your heart and manage your weight. But one thing we don't always remember is that your diet affects not just your weight, but your body from the top down, the inside to the outside. Your body transforms the foods you eat into the cells that make up your hair, nails, skin and bones, along with your brain, heart, blood and joints. You literally are what you eat.
Here are some of the key nutrients that keep your body in tiptop shape from head to toe.
At its staggering growth rate of 0.4 millimeters per day, it takes more than 2 years to grow 12 inches of hair. Add lean meats and beans to your diet to make the most of every millimeter. These foods will also give you zinc to help keep your body in hormone balance and prevent hair loss. B-vitamins from leafy greens, peas, tomatoes and carrots also support cell growth for healthy hair.
Boost your brainpower by noshing on foods with high ORAC (Oxygen Radical Absorption Capacity) scores—a sign that the food is rich in disease-fighting antioxidants. Plums, cherries, avocadoes, berries, navel oranges and red grapes top the ORAC charts. (Glance through the alphabetical list for more disease-fighting ratings at oracvalues.com.)
Considering your brain is about 80% water, drink at least 64 ounces of water per day. Essential fatty acids (named "essential" because your body cannot make them) help you grow brain cells and stay sharp, so feed your brain with regular doses of fish, nuts, seeds, avocado, and olive oil.
Good nutrition can keep your peepers peppy throughout the years. The antioxidants for brain health also help the eyes, but really keep your eye on including foods with lutein and zeazanthin (pronounced zay-a-za-thin). These carotenoids, found in spinach, collard greens and kale, protect the retina from macular degeneration.
Teeth & Bones
Everyone knows you need calcium for bone health, but are you getting enough? Most adults need between 1,000 and 1,200 milligrams of calcium daily. Low-fat milk, cheese, yogurt, almonds, spinach and soybeans are all good sources of dietary calcium. And calcium doesn't act alone! Its partner-in-crime is vitamin D, which is necessary for proper calcium absorption. Some fish and eggs provide this key vitamin, but there are not many natural food sources of this bone builder. Instead, vitamin-D is often added to milk, margarine and some breads and cereals.
Put a wiggle in your walk with gelatin and vitamin C. These nutrients are key precursors to collagen, the material that cushions our joints and keeps our tendons and connective tissue strong. Gelatin can be found in powdered supplement form or in your basic Jell-O mix. Boost your vitamin C intake with fruits and veggies, especially strawberries, oranges, pineapple, cauliflower and green peppers.
Soy and flaxseed both pack double punches when it comes to heart protection. Soymilk, edamame, tofu and other soy products are packed with cholesterol-lowering phytochemicals and heart healthy soluble fiber. Flaxseed is also another source of soluble fiber that comes with a side of omega-3 fatty acids, which may help reduce your risk of heart disease. Sprinkle some ground flaxseed in your oatmeal or yogurt, or even add it to your favorite baking recipe.
Protect your gut with probiotics. These powerful little bacteria support the natural environment in your intestine and combat disease-causing microorganisms. You can find yogurt, kefir and milk supplemented with probiotics. They are often under the name L. Acidophilus.
Fiber is also essential to a healthy gut. Whole grains, especially oats and bran, beans, nuts, fruits and vegetables can help you reach your goal. Getting your daily 20-35 grams of fiber keeps your gut and colon health moving in the right direction.
We'll wrap it all up, literally, with nutrition for the skin. It is important to nourish your body's largest organ. Maintain disease-free and healthy looking skin with alpha-lipoic acid (ALA). This antioxidant is more powerful than vitamins C and E, and protects your skin cells from damage and many of the elements it's exposed to each day. Get your fair share of ALA with spinach, broccoli and beef. Vitamins C, E, K, and A, as well as B-vitamins are also important for radiant, nourished skin. Enjoying a variety of colorful fruits and vegetables can help you reach the recommended amount of these vitamins.
