Corn And Keto: How Many Carbs Are Too Many?

Corn is a tricky food when it comes to the keto diet. While it is a nutritious food with various health benefits, it is also a starchy grain with a high-carb content. This means that even a small portion of corn could eat up a significant chunk of your daily carb allowance.

The keto diet is a very low-carb, high-fat, moderate-protein diet. Carbohydrates are the body's preferred source of energy, but on a strict ketogenic diet, only about 5% to 10% of energy intake is from carbohydrates. The reduction of carbohydrates puts the body into a metabolic state called ketosis, where it starts burning fat instead of carbohydrates for energy.

So, how many carbs does corn have? Well, it depends on the type and amount of corn. One cup of fresh, raw, yellow sweet corn has 27 grams of carbs, while an ear of corn contains roughly 41 grams. A half-cup of corn contains about 15 grams of carbs, and a standard serving of corn (about 100 grams) can contain around 16.7 grams of net carbs.

With these carb counts, corn is generally considered too high in carbs to be included in a keto diet. However, some keto dieters might be able to consume a very small portion of corn, such as a tablespoon or two, and still remain in ketosis.

Corn on the cob is not keto-friendly

The keto diet is a high-fat, moderate-protein, and very low-carbohydrate diet. The goal is to put your body into ketosis, which means it is burning fat instead of carbohydrates for energy. The standard ketogenic diet (SKD) recommends a diet consisting of high fat, low-carb, and moderate protein intake. Low-carb means a maximum intake of 50 grams of net carbs per day, and oftentimes much less.

Corn is not keto-friendly because it is a complex carb and a starchy grain containing more digestible carbs than fiber. It should be limited or avoided if you are on a low-carb diet. While corn is a good source of fiber, vitamins, and minerals, it is not usually appropriate if you are on a keto diet because of its high carbohydrate content, which could easily exceed your daily carbohydrate limit.

There are some keto-compatible alternatives to corn, such as cauliflower, zucchini, and bell peppers, which can be used as substitutes in keto dishes.

Corn is a grain, not a vegetable

Corn is often thought of as a vegetable, but it is actually a grain. While whole corn, like corn on the cob, is considered a vegetable, the corn kernel itself is a grain. Corn is a "whole" grain, meaning it is the entire grain, and it is the most popular crop in the world.

Corn is grown throughout the summer and is typically yellow, but it can also be found in other colours. It is used in many dishes, including tacos, burritos, polenta, fritters, soups, and sauces. It is also used to make corn oil, high-fructose corn syrup, corn flour, and fried corn tortillas.

Corn is a high-carb food and is not typically considered keto-friendly. One cup of fresh, raw, yellow sweet corn contains 27 grams of carbohydrates. For reference, the SKD (standard ketogenic diet) recommends a diet of no more than 50 grams of net carbs per day.

While corn is not keto-friendly, there are some corn-based foods that can be enjoyed in moderation while on a keto diet, such as popcorn and corn tortillas made with almond flour.

Corn is a complex carb

Corn is a smart carb, as it is low in calories and fat. One medium ear of corn (about 1/2 cup of kernels) contains less than 100 calories. It is also virtually fat-free, with only 1 gram, and is a good source of fibre, with 2 grams.

Corn is also a good source of antioxidants, with nearly twice the antioxidant levels of apples. It is also one of the least likely fruits or vegetables to be contaminated with pesticide residues.

However, corn is a high-carb food, and is therefore not typically considered keto-friendly. One cup of cooked corn contains 23-24 grams of net carbs, which is too high to fit into a low-carb diet or keto meal plan.

That being said, some keto dieters may be able to consume a small amount of corn and remain in ketosis. For example, those following a targeted or cyclical keto diet may choose to include a small amount of corn in their diet, mapping their carb intake around their workouts.

Corn is a starchy grain

Corn is a high-energy carbohydrate and is considered a starch. It is not typically recommended for a keto diet because it is high in carbohydrates, which could easily exceed the daily limit for those on a keto diet. An ear of corn contains about 27 grams of total carbohydrates, with a cup of corn having about 30 grams of carbs. Even a half-cup of corn contains about 15 grams of carbs. This makes corn a less ideal food for those trying to stay in ketosis.

While corn is not keto-friendly due to its high carb content, it does offer some nutritional benefits. Corn is a good source of dietary fibre, which can aid in digestion and promote feelings of fullness. It also contains vitamins and minerals such as vitamin C, vitamin B, folate, magnesium, potassium, and iron. Additionally, corn is rich in antioxidants, including beta-carotene and lutein.

For those on a keto diet, it is best to avoid corn and opt for low-carb vegetables such as leafy greens, broccoli, cauliflower, zucchini, and bell peppers. These vegetables have a lower carb content and will not disrupt ketosis. However, if you really miss corn, you may be able to include a very small amount, such as a tablespoon or two, into your daily carb limit. But even this small portion can take up a significant chunk of your carb allowance, so it has to be worth it.

Corn is high in natural sugars

Corn is a grain, not a vegetable, and it is packed with natural sugars and carbohydrates. In fact, corn is considered a starch and a high-energy carbohydrate. This means it is not keto-friendly.

A standard serving of corn (about 100 grams) can contain around 16.7 grams of net carbs, which is pretty high considering the strict carb limits of the keto diet. To put this into perspective, the keto diet recommends keeping carbs low, usually between 20 to 50 grams per day, to maintain a state of fat-burning known as ketosis.

Corn's high natural sugar content is what makes it less than ideal for those trying to stay in ketosis. In a typical 100-gram serving of corn, there are about 6.26 grams of total sugars. These sugars break down into different types: sucrose (0.89 grams), glucose (3.43 grams), and fructose (1.94 grams).

Sucrose is what we often think of as table sugar, a common sweetener in many foods. Glucose and fructose are simpler sugars, with glucose being a primary energy source for our bodies, and fructose being a bit sweeter and found naturally in fruits. These sugars are the main sources of carbohydrates in corn, contributing to its overall carb content.

While corn is a nutritious food that offers a good source of dietary fiber, vitamins, minerals, and antioxidants, its high natural sugar content can quickly use up your daily carb limit on a strict keto diet. This is why, despite its nutritional value and delicious taste, corn is usually not included in a strict keto diet plan.
