Best and Worst Snacks

Best and Worst Snacks

Eight not-so-healthy snacks, plus 8 easy, healthy alternatives.
By Elaine Magee, MPH, RD

What makes a healthy snack? A good-for-you snack is one that's high in nutritional value (protein, vitamins, minerals, fiber) but relatively low in calories, total fat, saturated fat (no trans fat), sugar, and sodium.  And the most important part of that equation is "high in nutritional value." Nuts, for example, are high in fat and calories -- but are also loaded with nutrients we need, which makes them a healthy snack.
On the flip side, not-so-healthy snack choices are usually low in nutritional value but high in calories, total fat, saturated fat (and sometimes trans fat), sugars, or sodium.
While fresh veggies and fruits make super-healthy snacks, those items aren't always convenient (or the top choices for your typical family). That said, here are some of the worst snack choices you can find in your local supermarket in terms of healthfulness -- along with some healthy alternatives you can buy or put together in minutes.

8 Not-So-Healthy Snacks

 1. Chocolate Coated Donuts, Mini Donuts, and Snack Cakes
This is not to say that powdered-sugar donuts are good snack choices. But chocolate-coated donuts and snack cakes have even more saturated fat than other types.

2. Snack Pies
The Safeway fruit pies even say "great snack!" on the package. This makes sense only if by "great snack," they mean high in calories, total fat, saturated fat, and sugar, and low in protein, fiber, and other healthy nutrients.

3. Mega-Butter or "Movie Theatre" Microwave Popcorn
This is one of the few products that still contain trans fat. Just 3 tablespoons of unpopped popcorn (which ends up being about 3.5 cups popped) contains 4-5 grams of trans fat. It's easy to end up eating twice that amount, which can be 8-10 grams of trans fat and 24 grams of total fat.

Two types of these snack-sized Lunchables contain about half a day's worth of the suggested amounts of fat, saturated fat, and sodium for someone eating around 2,000 calories a day.

6. Packaged Frozen Snacks
They sure seem convenient, but the calorie and saturated fat cost is high. You'd be hard-pressed to find packaged frozen products that are low in sodium and made with whole grains and smart fats. In this product category, it's buyer beware!

They may seem like a good snack choice because they're high in protein (14 grams). But there are ways to get your protein without all the extra fat, saturated fat and sodium.

8. Cheese Crackers
One serving (1 ounce) probably won't fill you up, since cheese crackers are low in water, volume, protein and fiber. So you’ll probably double the serving -- which means your snack now contains 300 calories, 18 or so grams of fat, 6 grams of saturated fat and 500 milligrams sodium.

8 Healthy Snacks to Try Instead

1. Toasted 100% Whole-Wheat English Muffin with Peanut Butter
You'll find at least two brands of 100% whole-wheat English muffin (Oroweat and Thomas) in most supermarkets. Toasted and spread with some natural-style peanut butter (the type that just contains peanuts and a little salt), these make a satisfying snack with 10 grams protein and 5 grams of fiber.

2. Planters Nut*rition Nut Mixes (or similar)
Don’t let the 15 grams of fat per serving fool you. Most of these fat grams are from beneficial monounsaturated fats (8 to 9 grams) and polyunsaturated fats (3 to 5 grams). Each ounce also contains at least 5 grams of protein and plenty of healthful phytochemicals like phytosterols and lignans.

3. 94% Fat-Free Microwave Popcorn
When you're craving something crunchy, microwave popcorn can be a quick and easy snack solution. There are now some lighter options on the shelves. Even if you double the serving size listed on the label, it still only adds up to 240 calories, 4 grams fat, and 1 gram of saturated fat -- along with 8 grams of fiber.

4. Quick Microwave Nachos (Baked chips with beans and cheese)
This high-protein snack (14 grams) is easy to put together. Just put an ounce of baked tortilla chips in a microwave-safe bowl and dot the top with small spoonfuls of the refried beans, right out of the can. Sprinkle some hot sauce or salsa over the top, along with a little shredded cheese. Pop in microwave for 30 seconds or so to heat the beans and melt the cheese. Jazz it up by adding chopped tomato, green onions, and a dollop of fat-free sour cream if you like.

5. Quesadillas
A quesadilla is quick to fix in the microwave or over the stove. If you use a whole-wheat or whole-grain tortilla and reduced-fat cheese, you'll get plenty of protein and fiber (12 grams protein; 8 grams fiber) for hunger-satisfying power. You can customize your quesadilla by adding nutrient-rich vegetables such as tomatoes, chopped green onions, peppers, or avocado.

6. Lower-Sugar Snack Bars
There are lots of types of snack bars out there, from bars made with granola or nuts or coated in chocolate or yogurt. Most contain plenty of sugar (usually about 12 grams), but there are a few (with 6 grams of sugar per bar) that dare to emphasize nuts instead of sweetness. Note that the grams of fat will be high due to the heart-smart fats found in the nuts.

7. Fun-to-Eat Frozen Vegetables
Vegetables can be fun to eat, like frozen edamame (green soybeans) from the pod. Just heat in the microwave (you can also serve them cold), open up the pods and snack away at the green soybeans inside. They're low in calories and packed with fiber and protein (8 grams fiber, 10 grams protein). If you're hankering for a potato-based snack, the frozen steak fries are usually the lowest in calories, fat, and saturated fat because they have a higher ratio of potato to crispy exterior.

8. Yogurt and Fruit Smoothie or Parfait
In just a few minutes, you can transform yogurt and fruit into a tasty parfait or smoothie. For a smoothie, combine 1/2 cup plain or vanilla yogurt  with 1/4 cup frozen berries or other fruit, half a banana (if desired), 1/8 teaspoon vanilla extract, and a pinch of cinnamon in a blender until smooth. Add crushed ice if you want. For a parfait, combine the yogurt, vanilla and cinnamon, then layer the mixture with some frozen fruit.

8 Best and Worst Exercises for Your Heart

8 Best and Worst Exercises for Your Heart

Not all workouts are heart healthy. Here's which exercises one cardiologist says guarantees a lifetime of cardiovascular fitness.

By Arthur Agatston , Arthur Agatston, MD, is a preventive cardiologist and Prevention's "From the Heart Doc." He is also a member of Prevention's medical advisory board.

Some days it seems I answer more questions about sports injuries than I do about heart health. It's partly because my patients know I'm pretty active (golf, tennis, Pilates...) but also because many people don't realize that while some activities are good for your heart, they can be hard on your body. To me, the key is to find what works well for both. Here's how I rank a variety of exercises in terms of their benefits to both your heart and overall health.

BEST

Interval training: This is unrivaled for preventing heart disease and diabetes, losing weight, and efficiently improving fitness. The strategy: Combine short bursts of high-intensity exercise with slightly longer periods of active recovery. So if you're a walker, you might alternate 3 minutes at normal speed with 1 minute at a brisk pace. Continuously raising and lowering your heart rate improves vascular function, burns calories, and makes the body more efficient at clearing fat and sugar from the blood.

Total-body, nonimpact sports: The more muscles involved in an activity, the harder your heart must work to fuel them all--thus, it grows stronger itself. Rowing, swimming, cross-country skiing, walking with poles...all recruit muscles throughout the body without beating it up. Add some intervals and you have the ideal workout.

Weight training: In a sense, this is just another form of interval training. You increase your heart rate during reps and recover between sets. By efficiently handling the demands placed upon them, strong muscles ease the overall burden on the heart. Use free weights, which recruit more muscles, engage your core, and build balance.
Core workouts: The reason I like Pilates, which strengthens my core muscles and improves flexibility and balance, is that it doesn't just help me play golf and tennis better, it helps me live better. In order to exercise vigorously--as well as carry groceries upstairs and weed the garden--you need a solid foundation.

Yoga: The calm it provides lowers blood pressure, making blood vessels more elastic and promoting heart health. It also strengthens your core.

Being active all day: People who are active in little ways the entire day (cleaning, gardening, running errands) burn more calories and are generally healthier than those who exercise for 30 to 60 minutes and then sit at a computer. Wear a pedometer to measure how active you are outside of your exercise time.
 
WORST

Running long-distance on pavement: I did a lot of this until various aches and pains, plus all the injured joggers I saw in my practice, made me realize that humans aren't designed for long-term pounding. Although running this way strengthens the heart, it wears out the body.

Any type of vigorous exercise you haven't trained for: This can range from shoveling snow to biking 20 miles on the first spring day. The excessive adrenaline that's released can prompt a heart attack in those at risk. For the same reason, never exercise hard without warming up.

Finally, don't let science (or even me) dictate your exercise. Research may show swimming is tops, but if (like me) you don't enjoy it, then don't torture yourself. Find something fun that you'll do consistently. Your mood will get a boost as well.
