Eat cornstarch Cornstarch can not only cause illness, but can also indicate the presence of underlying health problems, such as certain mineral deficiencies o metabolic disorders such as gestational diabetes. Therefore, when they feel intense and repeated cravings to consume cornstarch Without any preparation, it can represent a red light or warning to consult a health professional and rule out physical or behavioral disorders.
Cornstarch is derived from the endosperm contained in the heart of the corn kernelsIt is used in cooking as thickening agent of sauces, creams and desserts and, in some cases, as talcum powder substitute for bodyAlthough it shows no toxic effects in its usual culinary use, consumed directly and frequently by the spoonful, or the compulsive craving to eat dried cornstarch, can be associated with various mineral deficiencies already altered eating behaviors.
What is pica and why might it be related to cornstarch?
The pregnant women They may express a desire for indigestible or unusual things because of a mineral deficiency o a lack of nutrients such as zinc or ironThis is relatively common at this stage. This intense and persistent craving for non-food substances or materials is called picaAlthough it is mostly associated with children who eat dirt or paper, it can also manifest in adults, for example with the craving to eat raw cornstarchice, chalk or clay.
The symptoms of pica translate into a desire to eat substances such as hair, ice, sand, paint, dirt, plaster, soap or clayin addition to large quantities of cornstarch. A single craving is not enough for a formal diagnosis: according to clinical criteria, a pattern repeated for at least one month and verify that the behavior is not part of accepted cultural practices or better explained by another mental illness.
The affected individuals usually present mineral deficiencies that are detected in blood tests frequently performed to check levels of iron and zincThese are the most common deficiencies associated with pica. Your healthcare professional should also evaluate infections or lead poisoningbecause the soil, old paint, or some objects that come into contact with when eating soil or paint fragments may be contaminated.
The treatment of pica and compulsive cravings for cornstarch focuses on the replenishment of nutrients that are lacking (iron, zinc, or other micronutrients) in the solution of other underlying health problems such as high-risk pregnancy or digestive disorders, and in the change of behaviors through psychological or behavioral therapy. In some specific cases, medication is prescribed. drugs to control anxiety or treat associated illnesses.
You can find it on the internet Videos and channels dedicated to eating cornstarch (for example, baked cornstarch or toasted cornstarch in crispy blocks) that present this practice as something appealing or enjoyable. Although it may seem like a harmless trend, it is important to remember that normalize the consumption of large quantities of dry corn starch It can mask or reinforce a pica problem, contributing to unbalanced diets and aggravate metabolic disorders in susceptible people.

Cornflour, corn starch and metabolic health
La cornstarch, Also known as cornstarch, cornstarch flour o cornstarchIt belongs to the cereal group. From a nutritional point of view, it is a refined carbohydrate easily digestible that provides fast energybut it offers a poor profile of protein, fiber, vitamins and minerals when consumed in large quantities and in isolation.
Corn starch and refined corn flour are processed in such a way that they They eliminate a large part of the nutrients present in whole grains. Furthermore, they are digested very quickly, which causes a sudden rise in blood glucose. In fact, the glycemic index of corn starch It is very high, even higher than that of table sugar, which means that it can promote glucose spikes and, if abused, increase the risk of obesity, insulin resistance and type 2 diabetes in predisposed individuals.
Although its moderate presence in the diet should not be a cause for alarm, this corn derivative It is not characterized by its nutritional value.It is basically a source of calories from carbohydrates, with low fiber and micronutrientsA large serving of pure cornstarch can provide a significant amount of virtually empty calories. Furthermore, it has properties astringentesTherefore, people who tend to suffer constipation They should moderate their intake.
It is also used in the processed food industry modified cornstarch (modified cornstarch) as a thickening and gelling additive. This starch undergoes physical or chemical processes that alter its structure to improve its stability, but without providing nutritional value. Although it is not considered toxic in normal amounts, a diet high in products containing it can increase the load of refined sugars and starches and displace options richer in fiber and nutrients.
Another relevant derivative is the maltodextrin, which is obtained by hydrolyzing corn starch. This ingredient has the same calories per gram as sugar and is rapidly absorbed, also raising blood glucose levels. It appears as just another ingredient on many labels, but it acts as a hidden added sugar And it's worth keeping this in mind if you're looking to manage your weight, control diabetes, or follow a diet with fewer ultra-processed products.
Nutritional benefits and uses of cornstarch in cooking
Los carbohydrates They are the body's main source of energy and, according to international recommendations, should represent a high percentage of daily intakeCornstarch, when used appropriately in balanced recipes, contributes to providing available energy for the brain and muscles, especially in people with high energy demand as athletes or in certain life stages.
In addition, cornstarch is naturally gluten freewhich makes it a useful ingredient for people with Celiac Disease or non-celiac gluten sensitivity, provided the product indicates there has been no cross-contamination. It is used for thicken sauces, juices, soups and puddingsand also to create a crispier batter when mixed with flour in fried preparations.
In the kitchen, cornstarch is a flour Very versatile employed in:
- Infant feeding: atoles, baby bottles, baby food and compotes where it provides a soft texture and easy digestion.
- Pastry and bakerySoft breads, cakes, puddings, flans, custards, sponge cakes and pastry creams, improving the creamy and smooth texture.
- Savory cuisineHomemade ice creams, bright sauces, soups, stews and creams, as well as light batters for meat, chicken and fish.

Uses of cornstarch in personal care and home
Beyond the kitchen, cornstarch has numerous uses. practical applications in the home and personal careIts fine texture and ability to absorb moisture make it a simple and economical resource for different everyday situations.
- Skin care: it can be used as homemade talcum powder to relieve rashes, minor irritations, diaper rash, and sunburnprovided the skin is not seriously injured. Mixed with a little water, it can form a soothing paste.
- Fat and sweat control: applied in small amounts helps to absorb excess fat on very oily skin, already control unpleasant odors on feet or armpits, acting as a natural alternative to some deodorant powders.
- Cleaning and stainssprinkled on grease stains In fabrics, it helps absorb oil before washing. Mixed with other household ingredients, it can help with complex spots, like ink ones.
- Games and crafts: combined with water it can create a non-newtonian fluid very dense, with which children can safely experiment with textures if not ingested in excess, and can also be used to make modeling clay homemade.
Homemade tricks with cornstarch
- Greasy hairApplying a paste of cornstarch and water to the scalp for a moderate amount of time helps to absorb excess sebum before washing. Afterwards, rinse thoroughly with plenty of water to remove any residue.
- Rashes in babiesRubbing a little cornstarch on clean, dry skin before putting on the diaper can help. reduce moisture and chafingThis helps prevent minor irritations. If the skin is very red or has wounds, it is necessary to consult a pediatrician.
- Ink stainsMix cornstarch with milk until a thick paste forms, apply it to the affected area, let it dry and brush it off; this can help remove the stain before washing the garment normally.

Starch, flour and types of resistant starch
FALSEAlthough they are often used as synonyms, the starch and starch They are not exactly the same. Both are complex carbohydrates with similar uses and a very similar chemical composition, but Starches are obtained mainly from cereals such as corn, rice, or wheat, while Starches come from tubers like the potato or the sweet potato. This difference in origin can influence the texture and some culinary uses.
TRUENot all starch is the same. Starch is made up of two types of glucose molecules: amylose y amylopectinThe ratio between the two determines the digestion speed and the texture of food. Most starches are digested in the small intestine, transforming into glucose that passes into the bloodstream. However, there is a type of starch that It is not fully digested: The resistant starch, which reaches the colon almost intact and behaves similarly to fiber.
TRUE. The resistant starch act as a soluble fiber analogueSince it is not broken down in the small intestine, it reaches the colon where it serves as food for the microbiota, promoting the growth of beneficial bacteria. This can contribute to increase satiety, to favor a slower gastric emptying, help to moderate the glycemic index of meals and support the cholesterol reduction in blood in the context of a healthy diet.
TRUEResistant starch has a marked prebiotic effectWhen bacteria ferment in the colon, they produce short chain fatty acids such as butyrate, which strengthen the gut barrier, reduce the local inflammation and they can help protect against certain digestive tumorsespecially when it is part of a dietary pattern rich in a variety of plant-based foods.
FALSEIt is not difficult to obtain resistant starch from everyday food. There are several types:
- El Type 1 It appears in pseudocereals such as Quinoa, a whole grains like brown rice, in seeds and in vegetables like beans, when their physical structure protects the starch granules from digestion.
- El Type 2 It is found naturally in green bananas, raw potatoes, some legumes and in the amylose-rich cornwhere the granule structure hinders the action of digestive enzymes.
- El Type 3 It is formed when Starchy foods are cooked and then cooledsuch as potatoes, rice, pasta, or oats. When these foods are stored in the refrigerator for a period of time, some of the starch is reorganized into a form that is more resistant to digestion. They can then be eaten cold or reheated at a moderate temperature.
- El Type 4 is a artificially modified starch through industrial processes. Although it has some resistance to digestion, does not share all the benefits of natural resistant starches.
- Los Type 5 are generated when combine starch with fatsTheir effects on health are still being investigated, but they also seem to show some resistance to digestion.
TRUEStarch, especially in its modified form, is used in the food industry for to reduce cost and increase volume to many products. It acts as thickener, gelling agent, binder or stabilizerand is common in inexpensive cold cuts, sausages, cured meats, pastry fillings, sauces, and baked goods. In these cases, part of the product that appears to be "meat" or "filling" may actually be a mixture of starch and additives with little nutritional value.
FALSEResistant starch is not suitable for everyone. Those who suffer bacterial overgrowth in the small or large intestine, such as patients with SIBO or other microbiota disorders, may worsen your symptoms Consuming large amounts of foods rich in resistant starch can lead to fermentation in inappropriate areas of the intestine.
TRUEStarch can be considered a “hidden sugar” It is found naturally in many foods. It is present in rice, potatoes, pasta, and bread, but it is also added to processed products such as sausages, cold cuts, sweet fillings, pastries, sauces, crab sticks, cookies, or prepared soups. When corn starch is hydrolyzed, compounds such as the following are obtained: maltodextrinwhich behave in the body as rapidly absorbed sugars, contributing to glucose spikes It already contains excess calories if consumed regularly.
Corn, cornstarch and other derivatives in the current diet
El whole corn It is a cereal with an interesting nutritional profile: it provides fiber, vitamins, minerals and antioxidantsConsumed as cooked corn on the cob, low-fat homemade popcorn, or frozen kernels, it can contribute to digestive careIn the Cardiovascular health and the supply of micronutrients such as magnesium, phosphorus, potassium, B vitamins and carotenoid compounds beneficial for eyes and skin.
However, much of the corn consumed in modern diets comes in the form of highly processed derivativesRefined corn oil, corn starch, highly refined corn flour, and high-fructose corn syrup, among others. High and frequent consumption of these products has been linked to hypertension, hyperglycemia, obesity, fatty liver disease and a greater risk of metabolic and cardiovascular diseasesIn comparison, whole grain corn maintains a slower digestion and a more moderate impact on glucose.
Furthermore, a very important part of the corn production is destined for animal feedRegular consumption of meat from livestock fed large quantities of corn can result in fattier meats and a less favorable fatty acid profile than those fed mainly on grass, which also has repercussions on the overall diet of the population.
In countries with high availability of corn, corn derivatives appear on an extensive list of ultra-processed foodsSalad dressings, sweet and savory crackers, commercial sauces, mayonnaise, candies, breakfast cereals, commercial breads, pancake mixes, and baby products. Within this context, the corn starch and its modified forms They are frequently used as ingredients, which explains why some people may ingest unknowingly using large amounts of cornstarch.
Understanding these differences helps to situate the cornstarch in its correct place: like a useful ingredient in small quantities for cooking and thickening, but it should not become the main focus of the diet or an object of compulsive consumption. When the craving to eat cornstarch If it appears intensely, repeatedly, or in large quantities, it may be a sign that something is wrong at a level nutritional, metabolic or emotional and it is advisable to seek guidance from healthcare professionals.
