The 3 Veggies with the Least Nutritional Value on Shine

The 3 Veggies with the Least Nutritional Value on Shine

Amy Paturel, SELF magazine

We're not here to demonize any form of produce. After all, every veggie has at least some nutritional value -- and we all need to include more vegetables in our diets, not less!

But if you're wondering whether to use iceberg or romaine in your signature summer salad, you may want to check out our list of the veggies with the least nutritional value:

1. Celery: Sure, you can nosh on 8 inches of celery for only 6 calories, but are you really getting any nutrients in return? The answer: Yes, but you'd have to go beyond an 8-inch stalk, which provides a mere 1.6 percent of our daily requirement for calcium and 2 percent of our daily requirement for vitamin C. It does, however, boast a decent amount of fiber and vitamin K. A better alternative: Carrots, which are loaded with eye-protecting beta carotene. Toss them into salads for a low-calorie crunch; braise them as a sweet summer side dish or slice them thin and add them to your favorite stir-fry.

2. Cucumbers: The cucumber is another low-calorie veggie. One cup of sliced cucumber weighs in at only 16 calories. But it's slim on nutrients, too. In fact, cucumbers contain 5 percent or less of our daily requirement for potassium, manganese, magnesium and vitamin C. On the plus side, cucumber extracts (not the whole cucumber) do have a number of disease-fighting antioxidant compounds, like tannins and flavonoids, says Registered Dietitian and Chef Consultant Michelle Dudash. A better alternative: Purslane, a peppery herb that's high in heart-healthy alpha linolenic acid (a type of omega-3). It's also higher in beta carotene than spinach. Toss it in salads, fold it into omelets or use it as a crunchy green on sandwiches.

3. Iceberg Lettuce: Iceberg lettuce is one of the most commonly consumed vegetables in the U.S., along with potatoes (as French fries) and tomatoes, but that doesn't mean it's the healthiest option. While iceberg is low in calories and offers some vitamins and fiber, other dark leafy greens contain much more vitamin A and C. A better alternative: Romaine lettuce, which offers much more beta carotene than iceberg. Use romaine in a traditional wedge salad with blue cheese crumbles, diced tomatoes and balsamic vinaigrette, or layer it on turkey sandwiches.

3 Reasons To Run A 5-K

3 Reasons To Run A 5-K

Whether you're an eager newbie or a serial marathoner, there are loads of reasons to register for a 5-K.

"If you're a beginner, targeting the distance is a great way to gain motivation and build structure into your schedule," says Luke Humphrey, M.S., an exercise physiologist and head coach for Hanson's Coaching Services in Rochester Hills, Michigan. "For regular runners, the 5-K stokes your competitive spirit, breaks up the monotony of high-mileage training, and serves as a solid test of speed." In fact, all runners can improve their fitness—and maybe even their PRs—when training for a 5-K, says Humphrey. Here's what keeping it short and sweet can do for you.

Get Going: Try these exclusive 5- and 10-K Runner's World training plans for novice, intermediate and advanced runners.

1. Run It... for Motivation

For newcomers, a tangible goal like finishing a 5-K gives purpose to your training. It's amazing how committed to your mileage you become once you've paid an entry fee, says Carol Rewick, R.D., a coach for Fleet Feet Sports' No Boundaries 5-K training program in Vacaville, California. For longtime runners who typically target longer distances or race infrequently, the short event is an opportunity to hit the refresh button on your routine and rekindle your racing chops. "Lining up against other runners instantly gets your adrenaline going and your competitive drive humming," says Humphrey.

Train for it:

Beginners currently running twice a week for 20 to 30 minutes can aim for a 5-K that's five to six weeks away. Add another run to your schedule, do one set of 100-meter strides (fast running) during a weekly run, and tack an additional mile to your long run every week until you're up to at least five, says Blake Boldon, a RunnersConnect coach in Philadelphia. Returning racers: What are you waiting for? "If you're a fit runner, you could knock out a 5-K in two weeks, and it would feed into your training for almost any other race," says Boldon.

No training plan is complete without the proper fuel. Make sure you eat plenty of these best foods for runners.

2. Run It... to Boost Fitness

The intensity involved in 5-K training can boost your strength, speed, and hasten weight loss. "The anaerobic component of the workouts puts you out of breath, which teaches your body how to function at a harder effort, thereby improving your overall athleticism," says Boldon. Plus, he says, the race itself can be a useful training tool. "Your workout is going to be exponentially better in a race setting than if you run on your own."

Train for it: Once a week, run two to eight 200-to 800-meter repeats at goal race pace, or a speed where it's uncomfortable to talk. Between repeats, walk or jog 50 to 100 percent of the time it took to complete the effort. Do a weekly tempo run of two to six miles at 25 seconds slower per mile than goal pace.

Every couple of weeks, replace your tempo with a strength workout. On the road, grass, or a bridle path, run one to three miles at 10 to 20 seconds slower per mile than race pace, says Humphrey.

Stick to your running regimen with these motivating stories from other runners. Also, get great advice on proper gear, training and race day ettiquette.

3. Run It... to Nail a Time Goal

You're guaranteed a PR if you're running your first race. But for everyone else, the 5-K is an opportunity to nail a good-for-now time. "You don't have to race for your best finish ever—it could be your best this season, your best this year, or your best this decade," says Boldon. If your ultimate goal is a PR in a longer distance, use the 5-K to gauge how your speed is progressing. "You'll get instant feedback on your training so you can make adjustments to meet your goal," says Rewick.

Train for it: In pursuing a fast-for-now time, plot your races strategically to allow for sufficient recovery and buildup. After an event, run easy for a few days, then begin another three-to four-week training block before your next 5-K, using your most recent race time as a baseline. If you're training for a speedy half-or full marathon, schedule a 5-K in the beginning of your plan to establish a baseline pace for your workouts, then run another in the middle of your training to see if you're still on track, says Boldon.
