  2. A sweet potato and a yam are the same thing.
  3. Sweet potatoes should not be stored in the refrigerator.
  4. Sweet potatoes are more nutritious than white potatoes.
  5. Sweet potatoes have four times the recommended daily intake for beta-carotene.

Answers and Fun Facts:

1. TRUE. While it is a non-traditional way to eat this vegetable, sweet potatoes can be eaten raw. Cut them into strips and eat them like carrot sticks or grate a sweet potato into slaws or salads. To avoid browning, rinse the cut sweet potatoes in cold water before serving.

2. FALSE. If you are being botanically correct, the sweet, moist, orange-colored vegetable that is often thought of as a yam is the United States is actually a sweet potato. A true yam is a starchy edible tuber that is imported from Africa and the Caribbean. It is completely different in taste and texture from a sweet potato. Did you know that the USDA requires that those orange-colored sweet potatoes (that most folks think are yams) be labeled sweet potatoes?

3. TRUE. Avoid storing sweet potatoes in the refrigerator. Cold temperatures will produce a hard center and a bitter unpleasant taste. The best storage for sweet potatoes is in a cool, dry, well-ventilated container. No, a plastic bag is not a good storage option. For long-term storage, keep sweet potatoes at 55-60 degrees Fahrenheit. If a sweet potato is kept at above 60 degrees, then it will begin to shrink and sprout. Once you’ve cut or cooked your sweet potatoes, then they should be refrigerated.

4. TRUE. While sweet potatoes and white potatoes are similar in terms of carbohydrates, sweet potatoes are higher in fiber and vitamin A than regular potatoes are. Sweet potatoes also beat the white potato in vitamin C and potassium levels. Overall sweet potatoes are the nutritional winner.

5. TRUE. Sweet potatoes are a great source of beta carotene, which is the precursor to vitamin A. Sweet potatoes have more beta-carotene than carrots! If you eat your sweet potato with just a little fat, like a bit of butter, then you will maximize your body’s absorption of this fat-soluble vitamin.

6. FALSE. While a medium sweet potato is a good source of vitamin C (with 30% of the recommended daily value), one orange doubles that with 80% of your daily value of vitamin C. If you want to go over the top with vitamin C, then whirl cooked mashed sweet potato, orange juice, vanilla yogurt, and a little vanilla extract in the blender for a sweet potato smoothie.

7. FALSE. A medium sweet potato (2 inches by 5 inches) contains only about 100 calories. It’s frequently the brown sugar and marshmallows added to sweet potatoes that bring that calorie count up. Looking for lower calorie flavors that go well with sweet potatoes? Try orange, pineapple, apple, cinnamon, and nutmeg. There are some great recipe ideas over in the Food and Health recipe archives.

8. FALSE. Sweet potatoes are edible roots and white potatoes are tubers. Sweet potatoes are a member of the morning glory family and their flowers look very similar. Sweet potatoes are native to the United States.

9. FALSE. Depending upon the variety, sweet potatoes can be orange, yellow, red, white, or even purple.

10. FALSE. Why get stuck in a sweet potato rut? Use cooked mashed sweet potatoes in pancakes or in place of mashed pumpkin in muffins, pies, or breads.

Healthful Resolution Ideas

Some healthy resolutions

Have you broken your resolution before you really made it?  If you’re serious about starting the year off on the right foot I have an idea.

How about 12 attainable resolutions?  I always wonder why resolutions have to be large goals (like lose 100 pounds) or doing something major “cold turkey” (like stopping smoking).  I’m thinking resolutions should be something you could add to your life and small things that you really could do.

How about “add-on” resolutions?  Something like the 12 days of Christmas—Only I’m making it the 12 months of health (someone sing).  The idea is to change one small thing each month and then keep that accomplishment and add another the next month.

The idea is you start with one in January—say it’s getting more activity—it could be walking one night after dinner with your spouse or joining a one-day-a week-yoga class.  It doesn’t have to be 5 days a week to get you started.

February—add another goal but still keep up what you started in January. In February (since it is heart month) learn a little more about the sodium in the foods you eat. Read labels and work to reduce the amount of sodium you take in. Try to eat the recommended 2300 mg (or less of sodium) every day—and still do the January goal too.

March—add something else.  But the January and February changes should almost be a habit by then so keep it up.

Write it down.   Write your goal for each month in your new calendar right now.  Is it really a serious resolution if you haven’t spelled it out?  Reevaluate at the beginning of each month on how it’s going.

Here are 12 ideas you could incorporate into your life….if you already do some of these add your own or make them more specific for you.

  1. Add some activity to your life.  The ultimate goal would be at least 30 minutes every day of the week. But start smaller. Find something you like to do and keep it up.
  2. Pack a healthy lunch—if you eat out most days for lunch –switch to just 3 days a week and pack a lunch the other two. You’ll save money but could also have a more nutritious lunch.
  3. Eat dinner with the family—without the distraction of television or phone at least 1-2 nights a week. Research shows that families that eat together eat less fat, more fruits and vegetables and more dairy.  It’s also a great way to build strong family relationships.
  4. Eat breakfast –If you’re not a breakfast eater start with just a few days a week. Breakfast eaters are more alert, creative, perform better and are less likely to be overweight.
  5. Eat more fruit-make your goal to eat 1 piece or “extra piece” each day. You might even make it a challenge to find new fruit to try out.
  6. Eat more vegetables— Work to get a vegetable or one more vegetable into your diet each day—or if you can’t eat more each day try for at least a couple a week. Look for new mixtures in the freezer section of your grocery store.
  7. Watch less television—this is here because research has shown that people who watch less television weigh less.  Adults who watch more than 2 hours of television a day tend to weigh more than those who watch less.
  8. Eat less fast food –studies have found that those who eat at fast food restaurants more than two times a week were 10 pounds heavier than those who ate there less than once a week.
  9. Cut every restaurant meal in half…enjoy it twice. There are always opportunities to eat out. Instead of totally avoiding your favorites or time with friends and family ask for a take-out container when you get your meal and take it home for another meal.
  10. Eat more whole grains—Recommendations are to eat at least six servings of grain every day.  Half of them should be a whole-grain.
  11. Go meatless—how about a meatless Monday?  This could save you calories, money, saturated fat, increase fruits and vegetables, not to mention more variety.
  12.  Fill everyone’s plate at the stove instead of family-style on the table. This will help control portion sizes and overeating…just because it’s there (also less dishes to wash).

These are my ideas.  You know your diet and your health. What little changes can you make each month that may make a big difference at the end of the year?

I admit…you probably can’t do them all or all the time.  Be realistic.  But maybe try some.

Best wishes for a happy and healthy new year.
