Tips For Eating and Cooking Sweet Potatoes to Get All the Health Benefits

Cutting up Sweet Potatoes

They have a very high amount of beta carotene which gives us many health benefits (healthy skin, hair, teeth, bones, vision, plus helps with anti-aging, cancer prevention, decreases asthma symptoms and protection against sun damage).

How do we get the most beta carotene from a sweet potato?

It is best to cook them to get the most beta carotene, but not all methods are equal.

To confuse the issue, raw sweet potatoes contain the most beta carotene (see this chart at the U.S. National Library of Medicine).

So why not just eat a raw sweet potato?

The problem is that they have an enzyme inhibitor that stops the trypsin enzyme in your body from digesting proteins. This protein inhibitor is broken down in the cooking process; heating to 194 degrees Fahrenheit for several minutes inactivates trypsin inhibitors.

A raw sweet potato can make you fart!

They contain a sugar called raffinose; it is one of three plant sugars that are unable to be digested in the stomach. They get broken down in the intestines, making hydrogen and CO2 which makes gas. Raffinose is decreased by cooking in the same way raffinose is decreased in beans by cooking according to a Michigan State University study.

Which Cooking Method Makes Available The Most Health Benefits of Beta-carotene?

According to research sited at the U.S. National Library of Medicine, this is the amount of beta carotene left after the following processes:
• Oven-drying process: 89–96 percent
• Boiling: 84–90 percent
• Frying method: 72–86 percent
• Sun-drying process: 63–73 percent

Ok, let’s get cooking.

  1. This looks amazing and fairly simple to do. I have never made stuffed anything but these look simple enough to try sometime. I love how you made garlic zucchini noodles to go with the dish. That’s my favorite way to eat zucchini noodles. I use my spiralizer weekly. Definitely one of the best birthday gifts I have received.

  2. I’m a teenager who is absolutly in love with cooking, and I saw this on your youtube channel one day and I decided to make it for my parents. I really like the info you share, it’s really helpful. The reaction of my parents when they tasted the spagetti squash was so amazing. thank you for sharing this kind of info with all of us.

  3. hanks! My fiancé is an amazing cook but me, not so much! I made this today for dinner so he didn’t have to cook. It was great! Easy enough for this inexperienced cook and tasty enough for his experienced taste buds! I added A super reduced balasmic on top since we use it for Caprese salad and it baked onto The chicken really well. This recipe is a keeper! Any idea for a balsamic Like sauce to go with it?
