Sweet Potato

Sweet potatoes are so nutritious and easy on the palate, that they’re regarded as one of the world’s top 10 foods. Their sweet, creamy consistency makes it a favorite for anyone, from babies who are just getting started with solids, to older kids and adults. Even our furry family members (cats and dogs) love them and they are great for them too! 

While the most common sweet potatoes are orange, they come in different colors and shades, from yellow all the way to red and purple. Recently, purple sweet potatoes have gotten a lot of attention due to their role in the Okinawan diet — one of the Blue Zones where most people live over 100 years. However, both orange and purple sweet potatoes are a top dietary component in Blue Zones. 

Orange sweet potatoes are rich in beta-carotene, a strong antioxidant and the plant-based precursor of vitamin A. Therefor, they support our vision, our cells in general, the production of white cells, and our organs. Purple sweet potatoes are rich in anthocyanins, a powerful antioxidant. Both are rich in fiber and resistant starch which are important to maintain a healthy microbiome. And they are rich in vitamins B, vitamin C, copper, manganese and potassium. This means, they strongly support our immunity, metabolism, red blood cells, brain, heart, bones, muscles, and our children’s early development.

Sweet Potato Cooking Tips

How to Select & Store

How to select the best sweet potatoes

Choose sweet potatoes that feel firm. No need to get organic, since they are on the Clean 15 list! But still, be sure to rinse them well before cooking. Store in a dark, cool, place instead of refrigerating to lower acrylamide formation.

Poke Before Baking

Poke Holes On Your Sweet Potatoes

If you’re baking them, it’s a good idea to poke them multiple times with a fork. This helps the steam escape and prevents a sweet potato explosion in your oven!

Bake with Water

Limit acrylamide content with water

A dry environment with high heat levels leads to the formation of AGEs (Advanced Glycation End Products) which can affect our blood glucose. Bake them at 350° F or lower, and include a bowl of water to add humidity.

 

Keep the Skin

Cube your sweet potatoes before boiling

If you’re boiling your sweet potatoes, keep the peel to reap all that antioxidant power. Typically, they’ll be cooked in 10 to 15 minutes (when cubed). Test them with a fork, if it comes off easily, they’re ready. Add them to soups with other vegetables, grains or legumes!

Great for Babies!

Choose the Best Foods for You and Your Family

Sweet potatoes make a fantastic first solid for your baby! Simply mash your baked or boiled sweet potato and give it to them. They’ll love it! Don’t include the skin as it can pose a choking hazard. Store in your fridge for up to 3 days, or freeze for up to a month.

Prrrrfect for Pets!

Dogs and cats love sweet potatoes too! Whether you bake them some yummy treats or simply give them baked or boiled cubed, they will devour them! Avoid the skin because it’s hard for our furry friends to digest it.

Important Things to Know

Hover over each of the facts below to flip the tiles and learn more details!

How we cook sweet potatoes determines their Glycemic Index.

It’s true, boiled sweet potatoes have about half the glycemic index (around 45 GI) compared to baked sweet potatoes (80+ GI), which is considered high. If you’re controlling your blood sugar levels for health reasons, it is best to stick to boiling your sweet potatoes. Otherwise, just prepare them the way you and your family enjoy them the most. Children typically prefer them baked due to their sweet and creamy consistency.

Anthocyanins may help prevent cancer, heart disease, and neurodegenerative disease.

Anthocyanins are flavonoids found in dark red and purple fruits and vegetables including grapes, berries, red cabbage, and purple sweet potatoes. Consuming them regularly can help:

  • protect our cells from harmful oxidants that lead to cancer
  • ameliorate inflammation that can lead to cardiovascular disease
  • decrease brain oxidative stress, inflammation and neuron degeneration
  • improve cognition

Eating carotenoids regularly is associated with living longer.

Eating fruits and vegetables rich in carotenoids, including beta-carotene, is linked to multiple benefits, including:

  • longer lifespans
  • skin health and prevention of skin cancer
  • reduction in cardiovascular disease risk
  • eye health

To eat the peel or not to eat the peel? What do doctors say?

When it comes to essential vitamins and minerals, eating the peel won’t add a significant amount. However, the skin has ten times more antioxidants than the flesh when boiled, so it’s a good idea to keep it on your cubed sweet potatoes and eat it when making soups or other boiled dishes. When you bake or roast it, though, it loses 2/3 of its antioxidant power.

Should your sweet potatoes be organic or not?

Good news! Sweet potatoes are on The Clean 15 list. This list, together with The Dirty Dozen, are provided every year by the Environmental Working Group (EWG) to serve as guidance on whether we should buy organic or not. According to their tests, we’re good buying conventional sweet potatoes. Enjoy!

Eating deep fried sweet potatoes could pose a cancer risk

Fried sweet potatoes (as well as fried potatoes) are high in acrylamides, a potential carcinogen. This is because of the high temperatures they are cooked in, which are enhanced by their oil content. A whole-foods, plant-based diet does not include oil due to its high fat content and almost zero nutritional value. Consider using an air-fryer if you’re craving fries and skipping the oil. Soak your sweet potato slices for 15-30 minutes before cooking them. Also, make sure you don’t brown them.
