Some cooks use cornstarch instead of flour to gain their wanted consistency in specific recipes. It is also used in baked products or to coat meat and also vegetables.

Corn starch is generally used in incredibly tiny quantities once included to recipes. It contributes incredibly few calories and also no considerable vitamins or minimal. It has actually a minimal impact on your day-to-day nutrition.

Cornstarch Nutrition Facts

The complying with nutrition indevelopment is gave by the USDA for a one-tablespoon serving (8 grams) of cornstarch.


Cornstarch gives about 30 calories per tablespoon, primarily from carbohydprices. Tright here are 7 grams of carbohydprices, 0 grams of sugar, and also 0 grams of fiber. The carbohydprices in cornstarch come from starch.

In spite of its high starch content, study has said that uncooked cornstarch is a low-glycemic food. Studies indicate that it is absorbed slowly in the digestive system. However, research has likewise reported that foodstuffs through cornstarch (such as stew or pudding) have the right to have actually a high glycemic index.

It should be detailed, yet, that research study into the glycemic index of cornstarch is restricted and also available studies tend to be small and limited in scope. The University of Sydney, which maintains a large database of foodstuffs and their glycemic index, does not provide a number for cornstarch.


There is no fat in a one-tablespoon serving of cornstarch. Even a complete cup includes much less than a gram of fat.


Cornstarch gives no protein. A one-tablespoon serving provides zero grams and also even a full cup only offers 0.3 grams.

Vitamins and also Minerals

Cornstarch offers no substantial vitamins or minerals. Even if it is consumed in larger quantities than is typical in recipes, the powder does not contribute any substantial micronutrients.

Health Benefits

Many type of world who use cornstarch sometimes in recipes might not notice any type of substantial impact on their health and wellness by consisting of the powder in their diet. But there are some ways in which cornstarch might have the ability to impact health outcomes in pick circumstances.

May Be Helpful in Management of Hypoglycemia

Tbelow is some proof that a diet that consists of uncooked cornstarch might be useful for those who are managing hypoglycemia.

One research testimonial publimelted by the American Diabetes Association examined studies investigating the usage of cornstarch-based nighttime snack and also its capability to minimize nocturnal hypoglycemia, especially in those with type 1 or kind 2 diabetes. In one examine, researchers reported that raw cornstarch decreased nocturnal hypoglycemia by serving as a glucose reservoir in the intestinal tract, wbelow it is digested slowly over a period of 6 to 8 hours.

In an additional examine, researchers found that once participants via type 1 diabetes took a bedtime supplement of uncooked cornstarch for four weeks, they skilled a 70% reduction in the frequency of self-reported hypoglycemia 3 hrs after ingestion of the supplement.

Makes Liquids Easier to Swpermit

People who have actually obstacle swallowing—a problem referred to as dysphagia—may be able to use cornstarch to boost the viscosity of their liquids to make swpermitting simpler. Dysphagia is a condition that becomes more prevalent as we age. Thickened liquids are often used in the management of dysphagia to enhance bolus regulate. A bolus is a tiny mass of chewed food. Thickened liquids likewise assist proccasion aspiration and improve swenable safety.

Corn starch is one thickener traditionally supplied to thicken liquids for those via dysphagia. More newly, gum-based thickeners have been even more widely provided, but tright here has been some worry over the safety and security of gum thickeners, especially in babies.

Unfortunately, thickeners, consisting of cornstarch, deserve to cause liquids that are distasteful. These thickened drinks additionally boost the feeling of fullness bring about little incentive and also bad physiologic drive to consume them which can be problematic if weight maintenance is an issue.

Healthier Alteraboriginal to Corn Syrup

Some processed foodstuffs and even residence recipes call for corn syrup as a thickening agent. For example, you may view high fructose corn syrup detailed as an ingredient in some assets, such as fruit pies. Sometimes, cornstarch have the right to be used instead of corn syrup. This substitution may carry out health benefits, yet the proof supporting this advantage is restricted.

In one limited study, researchers compared health and wellness outcomes as soon as a tiny team of guys (21 full, 10 hyperinsulinemia, and also 11 non-hyperinsulinemic men) consumed a diet through 20% of the calories coming from either fructose or high-amyshed cornstarch. High amylose cornstarch is a kind of cornstarch that has actually been produced to have actually a greater level of amyshed and much less amylopectin.

After 5 weeks, researchers uncovered that once their examine participants consumed a diet high in saturated fatty acids and cholesterol, fructose increased the levels of danger components linked through heart condition, particularly in hyperinsulinemic men. Corn starch did not seem to provide the same increases.

The examine has constraints, however. First, it was conducted in 1989 on just a little group of men. Tright here has been some more recent connected study, however those researches were performed on mice. Also, the typical consumer is not most likely to find high amylose cornstarch on save shelves. They might only gain these potential benefits if food manufacturers usage it rather of corn syrup or high fructose corn syrup in processed foodstuffs.

Gluten-Free Alterindigenous in Recipes

Those with wheat allergies or that have celiac condition, non-celiac gluten sensitivity, or who follow a gluten-free diet for various other factors may usage cornstarch instead of flour in recipes. For example, in recipes that contact for you to usage flour to coat foodstuffs before frying or use flour to thicken sauces or gravy, you have the right to easily usage the majority of brands of corn starch as a safe and also straightforward alternate.

However before, it"s essential to choose your cornstarch closely and also look for one that particularly indicates that it is gluten-totally free. Pure cornstarch is cost-free from gluten and is a common ingredient in gluten-totally free foodstuffs.

That being shelp, cornstarch is subject to cross-contamination. Many type of brands that make cornstarch additionally make other kinds of flour. If the same devices is provided to manufacture and procedure corn starch and a gluten-containing grain, then the cornstarch might not really be gluten-complimentary.

May Impact Weight Loss

Researchers have thought about whether or not a diet that consists of highamylosecornstarch may be useful in the treatment of weight problems. Scientists have postulated that the slow-moving glycemic response to cornstarch may assist minimize appetite, boost satiety, and also minimize in its entirety energy intake.

However, in a examine entailing young healthy womales, the outcomes were not overwhelmingly positive. When the womales consumed a beverage containing the high amylose corn starch or glucose, the corn starch did not minimize appetite or power (calorie) intake also though glucose absorption was slowed.


Those via a corn allergy must protect against cornstarch. The Amerideserve to College of Allergy, Asthma & Immunology says that an allergic reaction to corn may reason symptoms that variety from mild to serious. These symptoms might encompass vomiting, stomach troubles, wheezing or challenge breapoint, weak pulse, skin transforms consisting of hives, swelling of the lips or tongue, dizziness, or confusion. In major cases, anaphylaxis might occur.

Adverse Effects

When it is consumed in typical amounts as food, cornstarch is safe for many human being. Tbelow have actually been some comes to around the inhalation of corn starch in work settings, but these cases are rare. Also, those that are allergic to corn starch need to be mindful that it was supplied on surgical gloves till the FDA banned it in 2016. 


When buying foodstuffs at your local industry you might view some products that incorporate "modified cornstarch" as an ingredient. Some consumers who are trying to avoid genetically modified (GMO) foods items may have concerns around the product.

However before, modified corn starch is simply starch that has been modified for food processing objectives. For instance, it might have actually been modified to boost a product"s shelf life. It does not indicate whether or not the corn it was made from was GMO or non-GMO. If you desire a non-GMO cornstarch look for the non-GMO label on the product you pick.

It is one of many kind of low-carb thickeners that have the right to be handy to have in the kitchen. But cornstarch is thicker, so usage around one tablespoon of cornstarch for every two tablespoons of flour required by the recipe.

When using cornstarch to thicken warm foods items (prefer gravy, soups, or stew) constantly blend it with a tiny amount of cold water or plant-based milk first. Then slowly stir into the warm liquid. Keep in mind, but, that if you are making a huge batch of soup or stew to freeze, cornstarch is not the ideal option of thickeners. When cornstarch is frozen it breaks down. So once your creamy soup or stew thaws, it will certainly be runny and thin.

Some cooks also add a little amount of cornstarch to recipes for baked items to include framework to treats like brownies, bread, cakes, and cookies.
