What is corn starch intolerance?

Corn starch itself isn’t inherently “bad”, it’s a common ingredient used to thicken sauces, soups, and baked goods. For most people, it’s fine in normal amounts. However, some people are sensitive for corn starch. They have a harder time digesting corn starch and this may trigger symptoms like bloating or gas.

What is corn starch intolerance?

Food intolerances are increasingly recognized as factors impacting digestive comfort, and while lactose and gluten intolerances are well-known, less common sensitivities like corn starch intolerance also deserve attention. Individuals with corn starch sensitivity can experience a range of digestive symptoms that affect daily well-being. Understanding the symptoms, causes, and management options for corn starch intolerance can empower those affected to navigate this sensitivity effectively. Products containing Gluco-Amylase can help you to reduce gas and bloating (1).*

What are symptoms of corn starch intolerance?

Corn starch intolerance symptoms can range from mild discomfort to more pronounced digestive disturbances. Common symptoms include bloating, gas, and abdominal pain. For some, these symptoms may appear within hours of consuming corn starch, while others may experience delayed symptoms, making it challenging to identify the cause.

Interestingly, symptoms of corn starch intolerance can overlap with those seen in potato starch intolerance, including bloating and gastrointestinal upset. However, it’s important to identify which specific starch triggers symptoms since effective management depends on avoiding the right ingredients. This awareness can help to recognize corn starch sensitivity as a distinct issue, making it possible to make informed dietary choices.

What are causes of corn starch sensitivity?

Corn starch intolerance often arises from the body’s inability to effectively break down starch molecules. This could stem from a lack of digestive enzymes needed to fully process starches, resulting in undigested starches fermenting in the gut, which can lead to bloating and gas. Additionally, an imbalance in gut bacteria can contribute to difficulty digesting certain starches.

While corn and potato starch intolerance symptoms may appear similar, individuals may react differently based on personal enzyme deficiencies or unique microbiome compositions. Recognizing corn starch intolerance as separate from other starch sensitivities helps individuals focus on specific dietary adjustments. The enzyme ‘Glucoamylase’ can help break down starches so they can be absorbed in the small intestine. A supplement that contains this enzyme is Starchway, which can help to reduce symptoms.* Starchway also contains the enzyme invertase. Which helps support the digestion of sucrose, which relates to Sucrose intolerance.

Can i consult a dietician?

If you suspect a corn starch sensitivity, seeking an accurate diagnosis can greatly assist in managing symptoms. The most common diagnostic approach is an elimination diet, where foods containing corn starch are removed from the diet for a period, and then gradually reintroduced. Noting any symptom changes during this process can provide clues about starch intolerance. Consulting a dietitian, particularly one specializing in digestive health, can also help confirm this sensitivity and provide tailored dietary recommendations.

How do i manage corn starch intolerance?

Managing corn starch intolerance begins with dietary adjustments. Reading food labels carefully and avoiding foods with added cornstarch is important. Many processed foods, sauces, and packaged snacks contain corn starch as a thickener, so identifying these products is key to reducing symptoms. Substituting corn starch with alternatives like tapioca or arrowroot starch can also help.

Additionally, certain digestive enzyme supplements can support starch digestion and can help reduce symptoms for those with limited enzyme production.* Try starchway stress-free!

How do i live with corn starch intolerance?

Navigating corn starch intolerance may initially seem challenging, but with the right information and resources, it can be managed effectively. Recognizing corn starch intolerance symptoms and understanding potential causes enables individuals to take proactive steps in adjusting their diet.

Is Cornstarch Bad for You?

Cornstarch itself isn’t inherently bad for you, in normal amounts, it’s a common thickening ingredient that most people tolerate well. However, if you have reduced Gluco-Amylase activity, cornstarch can be harder to digest and may trigger symptoms like bloating or gas. In that case, portion control or an enzyme supplement like Starchway may help support digestion.*
