Corn flour is typically not recommended for those on a keto diet due to its high carbohydrate content. With 7 grams of carbohydrates per tablespoon, corn flour can negatively impact ketosis and cause blood sugar imbalances, making it challenging for those on a keto diet to include in their meals. However, some people on keto diets may choose to include small amounts of corn flour in their recipes, such as 2 tablespoons in a crockpot of beef roast, which amounts to only 15 grams of carbohydrates. Additionally, there are several keto-friendly alternatives to corn flour, such as almond flour, coconut flour, xanthan gum, guar gum, arrowroot starch, and flaxseed meal, which can be used as substitutes in baking and cooking while maintaining the low-carb requirements of a keto diet.

What You'll Learn

Corn starch is not keto-friendly
Corn starch is also ultra-processed and has a high glycemic index, which means it can contribute to blood sugar imbalances linked to cardiovascular disease, obesity, diabetes, and other metabolic conditions. Additionally, corn starch may contain traces of glyphosate, a toxic herbicide linked to fertility issues and various cancers.
There are several keto-friendly alternatives to corn starch that can be used as thickeners or breadings. These include almond flour, coconut flour, xanthan gum, guar gum, and arrowroot starch. These alternatives are low in net carbs and can help thicken low-carb recipes without disrupting health goals.
Almond flour, for example, is widely used in keto recipes due to its minimal impact on blood sugar balance. It is also rich in essential vitamins and minerals, including vitamin E, calcium, iron, magnesium, and potassium, offering far more nutritional value than corn starch. Coconut flour is another popular option, providing nutritional benefits such as lauric acid, a health-promoting fatty acid with antiviral, antibacterial, and cardioprotective properties.
In conclusion, corn starch is not keto-friendly due to its high carbohydrate content, ultra-processed nature, and potential health risks. However, there are several keto-friendly alternatives available that can be used as substitutes in various recipes.

Almond flour is a good keto substitute
Cornflour is not keto-friendly as it is high in carbohydrates and can interfere with ketosis. It is ultra-processed and has a high glycaemic index, which means it contributes to blood sugar imbalances linked to cardiovascular disease, obesity, diabetes, and other metabolic conditions.
Almond flour is a widely used keto flour substitute. It is made from crushed almonds and is extremely low in carbs, containing only 3 grams of total carbs and 1 gram of net carbs per 2-tablespoon (14-gram) serving. It can be used as a 1-to-1 substitute for wheat flour in baking, although baked goods made with almond flour tend to be a little spongy. It can also be used as a breading for fried, air-fried, or baked foods.
Almond flour is also rich in essential vitamins and minerals, including vitamin E, calcium, iron, magnesium, and potassium, offering far more nutritional value than cornstarch. It is a good source of healthy fats and protein, which can help to increase feelings of fullness and provide important nutrients for the keto diet.
In addition to almond flour, there are several other keto-friendly flour substitutes available, such as coconut flour, lupin flour, chia flour, flaxseed meal, and pork rind crumbs. These flours can be used in baking and breading to create keto-friendly versions of favourite high-carb foods.

Coconut flour is another keto-friendly option
Corn starch is not keto-friendly as it is usually sourced from GMO corn and is high in carbohydrates. It has a high glycemic index, meaning it can raise blood sugar levels, trigger insulin release, and make it challenging to enter and maintain ketosis.
A 2-tablespoon (15-gram) serving of coconut flour provides 9 grams of total carbs and 4 grams of net carbs. It is one of the most popular and commonly used keto flours, often used alongside almond flour.
Other keto-friendly alternatives to corn starch include xanthan gum, guar gum, arrowroot starch, and gelatin. These ingredients can act as thickeners in low-carb recipes without disrupting health goals.
Keto-friendly flours are typically more nutrient-dense than gluten-free flour. Many gluten-free flour mixes contain rice, potato, corn, or tapioca starch, which offer minimal nutrition. Even healthier gluten-free mixes containing cassava flour or brown rice flour may still contain moderate levels of carbs and are not keto-friendly.

Xanthan gum is a keto-approved thickening agent
Corn flour is not recommended for those on a keto diet due to its high carbohydrate content. However, there are several keto-friendly alternatives to corn flour, such as almond flour, coconut flour, and lupin flour.
Xanthan gum is also very low in calories, with a 9-gram (2-tablespoon) serving containing only 30 calories. It is also a gluten-free alternative to conventional thickeners, which is beneficial for those on the keto diet, which consists mostly of gluten-free foods.
Xanthan gum can be used to make keto-friendly versions of sauces, muffins, and other recipes that typically use high-carb ingredients. It can also be used to make keto ice cream, soups, and smoothies. It helps trap the air bubbles created by leavening agents, allowing keto breads and baked goods to rise.
It is important to note that xanthan gum may cause digestive issues when consumed in large doses, such as 15 grams. Therefore, it is recommended to opt for non-GMO brands to minimize exposure to glyphosate.

Flaxseed meal is a vegan-friendly keto alternative
Cornflour is not recommended for those on a keto diet. This is because it is high in carbohydrates and has a high glycemic index, which can cause an increase in blood sugar levels, triggering insulin release.
Flaxseed meal, on the other hand, is a vegan-friendly keto alternative. Flaxseed is low in carbohydrates and does not contain gluten, making it ideal for the ketogenic (keto) diet. It is also a good source of fibre, with 100 grams of flaxseed containing 22.7 grams of fibre. Flaxseed meal can be easily made at home by blending flaxseeds in a food processor.
Flaxseed meal has a nutty flavour and can be used in both sweet and savoury recipes. It can be used as a replacement for eggs in recipes, as well as a substitute for wheat flour, although it is recommended to replace only about 20% of the wheat flour with flaxseed meal. Flaxseed oatmeal is a popular keto-friendly breakfast option. It can be made by blending flaxseeds and nuts into a coarse meal, adding milk, cinnamon, and a sweetener of choice, and then cooking over low heat or in the microwave.
Flaxseed meal can also be added to breakfast shakes, sprinkled over keto granola, or used as a topping for vegetables. It provides a boost of healthy fats, protein, and fibre, making it a nutritious addition to a keto diet.
