Healthy Veggies

White potatoes don't make you fat, carrots aren't made of sugar--and other myths about the produce you grew up on, dispelled

If the low-carb diet craze of the early 2000s left you believing that potatoes equal pounds and corn and carrots are no better than candy, it's time to wake up and taste the produce. Truth is, even vegetables you may think of as nutritional duds are packed with vitamins, minerals, and phytochemicals, not to mention varied colors, flavors, and textures. If you've been avoiding these "produce outcasts," your diet--and health--are missing out. Here, we debunk the biggest myths about a few unfairly maligned vegetables--and provide easy and healthful ways to eat more of them.

1. White potatoes make you fat

 

One medium baked potato has only 161 calories, plus 4 g of filling fiberAdded bonus: Chilled, cooked potato is packed with resistant starch, a fibrous substance that could help you lose weight. (For more information on resistant starch, visit prevention.com/resistantstarch.) "If you keep portion sizes in check--no more than one medium potato in a given meal--and eat the fiber-rich skin, potatoes make a satisfying, low-cal, nutrient-rich side dish," says Michelle Dudash, RD, a Gilbert, AZ-based nutritionist. They also:

Fight disease
When scientists from the USDA's Agricultural Research Service tested more than 100 potato varieties, they discovered 60 different vitamins and phytochemicals. For starters, they found flavonoids (which are credited with improving heart health and protecting against lung and prostate cancers) including quercetin, which may boost immunity.

Help maintain healthy blood pressurePotatoes are loaded with kukoa-mines, plant chemicals that help lower blood pressure, found the USDA researchers. In addition, one medium baked potato (including the skin) provides 20% of your daily potassium, a known hyper-tension fighter.

Try this: To make a fat-burning potato salad, boil new potatoes in water until cooked through. Cut into 1 2-inch slices and then quarter. Toss with olive oil, red wine vinegar, Dijon mustard, and chopped fresh parsley, and chill. Or for a hearty meal, skip the sour cream, butter, and cheese, and top a baked russet potato with vegetarian chili.

2. Iceberg lettuce has no nutrients

 

It has plenty of good-for-you compounds
Just because darker varieties have a few more is no reason to banish it! Iceberg also:

Boosts bones
Just 1 cup of shredded iceberg lettuce delivers nearly 20% of your daily dose of vitamin K, a nutrient many women don't get enough of. When Harvard University researchers tracked the diets of more than 72,000 women, those who ate one or more servings a day of any type of lettuce (they're all rich in the vitamin) had the lowest rates of hip fracture.

Protects your sight
Iceberg lettuce is a good source of vitamin A (just 1 cup supplies 15% of your daily dose), needed to keep your vision sharp.

Inches you toward "five-a-day"
If iceberg is your favorite lettuce, don't hesitate to use it as the base of a tossed salad. "Any lettuce that keeps you eating salads is a great vehicle for getting more produce into your day," says Dawn Jackson Blatner, RD, a spokesperson for the American Dietetic Association. Remember: Even the most nutrient-rich lettuce does you no good if it ends up in the trash.

Try it: Grilled! For a unique, smoky flavor, halve or quarter a head of lettuce and grill just long enough for the telltale marks to form (about 4 to 5 minutes). Remove from heat, core, chop, and dress. For an Asian twist, toss with sesame oil, grated fresh ginger, minced garlic, and rice wine vinegar.

 

3. Carrots are loaded with sugar

One cup of chopped raw carrots contains just 52 calories and a mere 12 g of carbohydrates
Only half of the carbs are from natural sugar (the rest are from heart-healthy fiber and complex carbohydrates). That's fewer than you'd get in a cup of milk or a medium-size piece of fruit. Plus, the sugar in carrots comes packaged with vitamins, minerals, and fiber, unlike the excessive empty calories you'd get from foods with added sugar, such as a candy bar or cookies. They also:

Benefit blood sugar
Fiber and beta-carotene, which are both linked to improved blood sugar control, are abundant in carrots. Improve your eyes A half-cup has more than four times the amount of vision-boosting vitamin A that you need in one day.

Promote colon health
Carrots are packed with falcarinol, a phytochemical that may help protect you against colon cancer.

Try this: Toss grated carrots into marinara sauce and simmer for added depth and a meaty texture (minus the fat found in beef), shred into tuna salad, or roast slices and add them to pizzas or sandwiches.

4. Celery is just water

Before the 1500s, celery was used as a medicine to treat a laundry list of ailments
Its devotees were on to something--the crunchy veggie has a unique combination of disease-preventing vitamins, minerals, and phytochemicals. It also:

Keeps your blood pressure down
Celery contains pthalides, rare compounds that lower your blood pressure by relaxing artery walls.

Lowers cancer riskThis veggie packs a dose of apigenin, a potent phytochemical that protects against cancer by inhibiting gene mutations.

Helps you stay slim
Celery sticks can satisfy an urge to munch with virtually no calories--one large rib has just 10 calories and 1 g of filling fiber.

Try this: Make a mirepoix--a flavorful base for soups, stews, and sauces often used in French cooking. Combine equal amounts of finely chopped celery, onions, and carrots. Sauté in olive oil until just softened, and proceed with your recipe.

5. Corn is nothing more than carbs

Sure, corn has carbs. But they're the best kind--high-quality complex carbs
The whole plant has little in common with high fructose corn syrup, a sweetener made from corn that has had all the nutrition and fiber processed out of it. Corn does double duty as both a veggie and a whole grain, so it's loaded with fiber (one large ear has 15% of the fiber you need in a day). It also:

Helps your heart
Corn kernels have heart-healthy folate, a B-vitamin that keeps blood levels of potentially dangerous homocysteine in check--one ear has more than 10% of your needs for the day.

Gives you energy
One ear of corn has more than 25% of the RDA for the mineral thiamin, which helps your cells convert carbohydrates from food into energy.

Preserves your vision
This veggie's also a top source of zeaxanthin and lutein, plant chemicals that keep your eyes healthy by preventing age-related macular degeneration.

Try this: For a simple corn salsa, toss together fresh or thawed frozen corn kernels; finely chopped jalapeño chile pepper; chopped fresh cilantro, tomato, and onion; and a pinch each of chili powder or ground cumin. Serve on top of mixed greens or grilled fish or chicken.
