Potato 101

Potatoes are a staple in many households. While potatoes may have a bad reputation, they’re versatile (baked, mashed, fried, boiled) and nutrient rich. They are an excellent source of vitamin C and potassium.

Potatoes

Keeping an eye on your blood sugar? You can still enjoy potatoes. Compared to many vegetables, potatoes may raise blood sugar quickly. However, the effect on your blood sugar is influenced by the type of potato and cooking method. For example, a white potato can increase blood sugar more quickly than a sweet potato, while a boiled russet potato raises blood sugar more slowly than a baked russet potato.

It’s also important to look at your entire meal versus just one food. When you enjoy potatoes with foods higher in protein and healthy fat, the potato is digested more slowly, which slows the rise of blood sugar.

FUN FACT: Don’t store potatoes with apples. Apples and many other fruits produce ethylene gas, which promotes sprouting.

“Watermelon—it’s a good fruit. You eat, you drink, you wash your face!”—Enrico Caruso

Watermelon is delightful, no doubt. It’s a sweet, low-calorie, fat-free food. Did you know watermelon is also a good source of vitamins A, B6, and C? Vitamin A promotes good eyesight. Vitamin B6 helps make antibodies and maintains blood sugar and nerve function. Vitamin C helps heal wounds.

Watermelon is a good source of potassium and magnesium, which aid in muscle and heart function. It’s 92% water, making it an excellent thirst quencher. Finally, watermelon is high in lycopene. Lycopene reduces blood pressure and cancer risk and maintains healthy skin.

Easy ways to enjoy watermelon:

  • Cut up bites of fresh watermelon.
  • Dip in yogurt.
  • Blend into a slushy or smoothie.
  • Freeze and enjoy as a fruit popsicle.

Why You Might Need More Potassium

Vegetables

If you read Nutrition Facts labels, you may have noticed they now list the potassium content of foods. So why is potassium a mineral we need to pay attention to?

For starters, potassium controls your heartbeat, builds muscle, and helps your body make proteins. Potassium can protect you from heart disease, stroke, muscle wasting, osteoporosis, and kidney stones. If you get enough of it, you can lower your blood pressure and cut your risk of dying from all causes by 20%!

Potassium is in many common foods, such as bananas, citrus fruits, potatoes, broccoli, milk, yogurt, beans, and leafy greens. However, fewer than 2% of adults meet their daily recommended potassium requirement. Adults should aim for 4,700 mg of potassium a day.

For example, this is one potassium-rich meal that would fulfill 40% of that requirement:

1/2 cup Swiss chard480 mg
1 baked potato610 mg
3 ounces turkey breast249 mg
1 cup low-fat milk366 mg
1 cup fruit cocktail225 mg
Total1,930 mg

Please do not rush out to buy potassium pills. High-dose potassium supplements can disrupt heart rhythm. They are also dangerous for those who have undetected kidney disease. Enjoy your potassium by eating a variety of fruits and vegetables!
