One of the biggest benefits of chowing down on some sweet potato goodness is that it will improve the health of your gut. 

This may not come as a surprise considering all the fibre and mélange of antioxidants that this vegetable contains.

2. Combat Cancer

In purple sweet potatoes, a group of antioxidants called anthocyanins are found which can considerably slow the rate at which some cancer cells (namely bladder, colon, stomach and breast) grow. 

Yes — this has been scientifically proven!

3. Improve Cognitive Function

Although no studies have been conducted to test improved brain function thanks to sweet potatoes on humans, research into the effects on rodents has been done. 

The findings were that this root vegetable does protect and improve our brain capacity as the anthocyanins stop free radical impact and reduces inflammation in the tissue. 

4. Maintains Healthy Vision

Sweet potatoes contain an incredibly high amount of beta-carotene which is what makes the vegetable that brilliant orange colour. 

Once you eat it, the aforementioned beta-carotene is turned into vitamin A by your body which promotes the health of your light receptors in your eyes. 

5. Supports Immune System

Vitamin A (given by beta-carotene, as mentioned previously) is essential for a healthy immune system. 

Luckily, sweet potatoes have this in abundance — especially the orange coloured ones — so you can expect to see a rise in your immune system's health. 

6. Regulates Blood Sugar Levels

Type 2 diabetes is caused because of an imbalance between blood sugar and insulin output. Luckily, these root vegetables can decrease bad cholesterol and fasting blood sugar as well as heightening your body's sensitivity to insulin. 

3 Ways to Cook Sweet Potatoes in The Oven

Hopefully, by now you will realize the importance of incorporating sweet potatoes into your diet. However, cooking healthy sweet potatoes is a different story as it is easy to just make some fries with them and call it a day — this isn't the best idea for your health. 

There are a few different ways of cooking sweet potatoes healthily, 3 of which we will discuss. 

1. Oven-Baked Sweet Potatoes

When we mentioned cooking this vegetable in an oven, this is probably the first idea you thought of. 

It is super easy to do and all you need are sweet potatoes and olive oil (really any type of oil will do, pick your favourite!).

Make sure you wash them first and pierce them with a fork afterwards to allow the steam to escape during baking. 

Once you have done that, oil the outside of them and wrap them up in tin foil. 

Then, simply bake for 45 minutes. 

2. Roasted Sweet Potato Chunks

Another way of how to cook sweet potatoes in an oven healthily is to roast them. 

Don't worry, it's pretty much the same as baking but you just need to ensure you peel and cut them up into cubes. 

It will take around 35-45 minutes to roast the chunks so the best idea is to come back at the 35 minutes mark and check on them. 

3. Sweet Potato Crisps

If you are a snacker by nature, then you are guaranteed to love this healthy yet tasty and crunchy snack that you can make for yourself. 

Wash the vegetable as usual but make sure to slice it very finely this time. 

Then, put them on a tray in a low-temperature oven to dehydrate them. 

After this, whack the heat up to turn them crispy and ét voila! You're all finished.
