Restricting carbs can zap energy levels and compromise the quality of workouts
Not since the public outcry against fat has there been such uproar about
popular nutrition--the message in the mainstream media seems clear:
It's protein you want not carbs! With all the hype, no wonder so many of
us are second-guessing our eating habits. In truth, the message about
carbohydrates has been so over-simplified that many people are skimping
on the most critical energy source the body has.Restricting carbohydrates can zap energy levels, compromising the quality of workouts and negating the benefits of a fitness program.
Here's the simple truth: There are many high-carbohydrate foods beneficial to both your health and athletic performance. The key is choosing the right carbs.
1. Rolled Oats
Heart disease still tops the charts as the No. 1 cause of death among women, so it's no surprise that the Food and Drug Administration recommends women on a 2,000-calorie daily diet eat about 30 grams of fiber a day.
With a mere half cup of cooked oats providing four grams of dietary fiber, adding rolled oats to your diet will help you meet this recommendation.
Fiber not only helps reduce risk for heart disease, it slows glucose absorption into the bloodstream, helping maintain peak energy levels and curb appetite. Rolled oats are also an excellent source of B vitamins (great for stress management and energy production) and contain a significant amount of zinc for immune function.
2. Lentil Soup
Lentils produce a low-glycemic response, meaning you won't experience a spike in blood sugar followed by an energy-sapping crash. Also loaded with dietary fiber (eight grams per half-cup serving), lentils provide the feeling of satiety, helping mute those intense cravings for sweets. Lentils also are packed full of folic acid, a nutrient essential for keeping cardiovascular risk low and guarding against birth defects.
3. Fresh Figs
Just three figs provide a whopping 30 grams of good carbohydrates along with a multitude of B vitamins, calcium and potassium to help ensure peak muscle function and optimal bone health. Figs also are an excellent source of soluble pectin fiber, shown to lower cholesterol and ultimately reduce cardiovascular risk. For a tasty snack, try serving quartered fresh figs with a dollop of reduced-fat ricotta cheese or flavored yogurt.
4. Roasted Chestnuts
In comparison to other calorie- and fat-dense nuts, chestnuts contain less than one gram of fat per ounce while providing a hefty dose of fiber, vitamin C and folic acid, nutrients important for immune function, formation of collagen and reduced risk for cardiovascular disease. Chestnuts are tasty in stuffing, pilaf, vegetable side dishes and soups. Or try them as a snack by themselves.
5. Blueberries
A one-cup serving and a mere 80 calories later, you get 20 grams of energy-enhancing carbohydrates, four grams of appetite-curbing fiber as well as a significant amount of vitamin C, a potent antioxidant that keeps the immune system revved. Blueberries have the highest ORAC (oxygen radical absorbance capacity) score of any fresh fruit, which means they can destroy free radicals in the body before they cause damage to healthy cells.
In addition, the dye that makes blueberries "blue" has been shown to improve memory, balance and coordination. Blueberries are a tasty addition to cereals, salads and smoothies. In the colder months when fresh blueberries are less prevalent, opt for the frozen variety.
6. Low-fat Plain Yogurt
Yogurt has always been touted as a nutritional powerhouse, partly because it's loaded with calcium, a critical nutrient considering osteoporosis affects 20 million women each year. Rich in vitamin B-12, yogurt also helps prevent fatigue. And plain yogurt just may be the perfect recovery food for athletes, as it promotes glycogen replenishment and muscle recovery.
Give yourself an energy boost after your next workout by slicing a ripe banana into a cup of plain yogurt. Make sure your yogurt contains active cultures called probiotics, hugely beneficial to immune function.
7. Rice Bran
The USDA reports more people are eating refined white bread, which lacks quality nutrients due to processed flours. Rice bran boasts superior nutritional credentials, with five grams of carbohydrates and more than two grams of fiber in a mere two tablespoons.
Furthermore, it provides 23 percent of the RDA for magnesium, a nutrient directly responsible (along with calcium) for the production of adenosine triphosphate (ATP), for energy during metabolism, as well as conversion of glycogen to glucose for use as the body's fuel during exercise.
Rice bran can replace up to half the flour in any quick bread or muffin recipe and be added to recipes for meatloaf and casseroles. If you don't plan on baking in the near future, try sprinkling rice bran on cereal, salad or yogurt.
8. Whole Wheat Pasta
Despite some concerns about the glycemic response of large portions of pasta, this common carbo-loading meal can be a healthful addition to your diet. Whole wheat pasta provides nearly 40 grams of energy-rich carbohydrates per one cup (cooked) serving. In addition, whole wheat pasta provides five grams of dietary fiber, most of it insoluble fiber, shown to reduce risk for breast cancer.
To ensure you are buying the healthiest whole wheat pasta, look for at least four grams of dietary fiber and five grams of protein per two ounces dry (or one cup cooked) serving. Be sure to watch portions and try to add a protein (chicken, ground sirloin) to your plate to avoid craving that second pasta portion. And, of course, add some veggies for color, fiber and an array of health-enhancing nutrients.
9. Sweet Potatoes
Despite this vegetable's impressive nutritional profile and appealingly "sweet" flavor, consumption of sweet potatoes is on the decline. A look at the facts might change your mind about this nutrient-dense veggie: A four-ounce sweet potato contains a mere 143 calories with a whopping 28 grams of carbohydrates and more than 100 percent of your daily requirement for beta-carotene.
A sweet potato also packs in more than a quarter of your daily needs for vitamins C and E, nutrients shown to prevent cell damage in athletes competing in extreme environments (altitude, heat, cold, pollution), as well as enhance muscle recovery after intense training. Sweet potatoes are also an excellent source of iron. Expand your intake of sweet potatoes beyond Thanksgiving by stirring them into chili, adding some to your favorite potato salad recipe, and adding shredded raw sweet potato into hamburger, meatloaf and meatball mixtures. Also, try using mashed sweet potato as a ravioli stuffing.
10. Oranges
Considered by many to be winter's most delicious fruit, oranges are rich in natural sugars for a quick energy boost, yet provide three grams of fiber for sustained energy. In addition, just one navel orange meets an entire day's requirement for vitamin C, while providing immune-enhancing flavonoids, helping to keep colds and flus at bay.
Your heart will also benefit from the folate in oranges. Opt for the whole orange (rather than juice), and be sure to eat the spongy inner layer that lies right under the colorful part of the skin to ensure you are receiving energy-sustaining fiber. Besides using oranges as a tasty, convenient snack, try adding sections of oranges to salads or smoothies, or using the juice as a marinade for meat.
Understanding Glycemic Index
The rate at which carbohydrates raise blood sugar and consequent insulin is measured by glycemic index. Carbohydrate-rich foods with a high-glycemic value enter the bloodstream rapidly, leading to a quick rise in blood glucose and the release of insulin.
A survey conducted at Harvard University's School of Public Health determined that 16 of the top 20 carbohydrates eaten by Americans are high glycemic. In fact, high-glycemic snack foods comprise 25 percent of the total caloric intake in the United States. Among the most popular are french fries, white bread, cereals with added sugar, soda, pizza and muffins.
In contrast, low-glycemic foods, which tend to be higher in fiber or contain protein, are converted into glucose slower than high-glycemic foods and, therefore, less insulin is needed to regulate blood sugar. About 50 to 70 percent of an athlete's total daily calorie intake should be from low-glycemic carbohydrates (three to five grams per pound of lean body weight). And no more than 10 percent of the calories eaten at rest should be from high-glycemic foods.
Good Choices: Enjoy sweet potatoes, old fashioned oatmeal, energy bars (Clif, PowerBar), beans, low-fat dairy foods, most fruits, 100 percent whole wheat or whole grain bread, oatmeal, nuts, whole wheat pasta, green peas, hummus and rice bran.
Foods to Avoid: Steer clear of sugared soft drinks, processed grains (white bread), french fries, pastries, scones, sugared cereals, syrup, whipped cream, chips and movie popcorn.
