People often use too much cornstarch to make their soup or stew good enough.

If you use cornstarch on a regular basis, it will certainly affect your heart health. Also, foods that have a high glycemic index and that are rich in carbs are most likely to cause heart diseases. But, such dangerous side effects are mostly linked to using excessive cornstarch regularly.

Overusing cornstarch might also result in obesity in the long run, which is not good for your cardiac health either. Make sure to keep your cornstarch consumption in check if you want to avoid spending an arm and a leg on cardiac medicines.

2.   Has a High Glycemic Index

As already established, cornstarch has a high glycemic index. It is very likely to increase your blood sugar levels which is very harmful to people with recurring diseases related to blood sugar levels.

Cornstarch is also low in fiber content. Fiber is mainly responsible for slowing down sugar absorption in the blood, so the sugar levels do not hike abruptly. But, being low in fiber, cornstarch is very likely to increase your risk of worsening your diabetes.

3.   High in Carbs

Cornstarch is dangerously low in nutrients and high in carbs. It means it is not only high in calories but has no worthwhile nutritional standing. Though it still has some micronutrients that are negligible.

You hardly use 1-2 spoons of cornstarch, and the concentration of micronutrients in a few tbsp does not make that big of a difference. If you are still using cornstarch, make sure you use it with nutrition-rich veggies and other food items to compensate.

Also, being high in carbs, cornstarch is not a good option for you if you are on a diet. Most diets require you to keep an eye on the number of carbohydrates you consume in a day. If you keep fueling up on cornstarch, you might gain weight instead of shedding those extra pounds.

Are There Any Replacements for Cornstarch?

Yes, there are a lot of replacements for cornstarch in the market, like potato starch and rice flour. Though these replacements might not make your broth thicker, they are much less harmful than cornstarch, so it is a win-win situation.

Below are the best substitutes for cornstarch, so make sure to give them a read just always to have a safer option for a creamy mushroom soup.

Potato Starch

Potatoes are not a grain. It is easy to use potato starch as a substitute. All you need to do is crush your potatoes and collect all the starch from them. Then let the starch dry in a powder.

So, this starch is also pretty high in calories and has a rather bland taste. It will not add much flavor to your overall recipe, so you can experiment with different flavors if you want.

Rice Flour

Rice flour is also a pretty good substitute for cornstarch. You just have to grind the rice and use it in place of cornstarch. People already use rice flour in soups and desserts, which are commonly available in marts.

Rice flour is gluten-free so that more people could use it, and it could as easily be used as a thickener in different dishes of your choice. You might need to add double the quantity of cornstarch if you want the same consistency.

When you mix rice flour with water, it turns colorless, so you can also use it in different desserts like puddings.

Wheat Flour

Wheat flour is pretty high in protein and other nutrients, so it is a far better thickening agent than cornstarch. However, you would need to use a lot of wheat flour to have the same effect as cornstarch. All you need to do is grind the wheat to make this flour.


Cornstarch is not the ideal thickening agent, but still, our soups are incomplete without it. So, make sure that you are not using a lot of it, and if you have diabetes or other heart diseases, just don’t use cornstarch altogether.

There are a lot of substitutes of cornstarch in the market that work just as good so, so the answer to “is it safe to use cornstarch?” is that no, it is not safe to use cornstarch recklessly, and you would have to keep a proper check on your consumption to keep your health hunky-dory.
