Corn, as is called here in the US is an essential ingredient in many foods. It is a grain, and like all grains, it is composed of carbohydrates. The three main types of carbohydrates are sugars, starches, and fiber. All grains contain all three of these carbohydrates. Corn is no different.
Corn is an annual grass that was domesticated in Mexico about 10,000 years ago. It was then introduced to the Eastern and Southern United States by Native Americans. Corn is now grown all over the world and is a major food crop.
Corn is used in many different products including cereals, chips, tortillas, crackers, bread, pastas, pancakes, muffins, cookies, biscuits, pies, cakes, candy, corn syrup, and ethanol. It is also used as livestock feed and as a biofuel.
What is corn?
Corn is a grain that is found in many different types of food. It is often used as a thickener or filler, and it provides a good source of dietary fiber.
What is a corn meal?
Cornmeal is made from ground corn, and it can be used to make bread, pancakes, and other baked goods.
What is a corn gluten meal?
Corn gluten meal is made from the protein found in corn kernels. It is often used as a protein supplement in animal feed.
What is whole grain corn?
Whole grain corn is the entire kernel of the corn, including the germ, endosperm and bran. It can be ground into a flour or meal, and it is a good source of dietary fiber.
Corn is a controversial ingredient in dog food. Some people believe that it is an unnecessary filler while others believe that it is a healthy source of carbohydrates and fiber.
What are the problems of corn and corn meal in dog food? 6 Key Problems
As mentioned before, some dogs are allergic to corn or have difficulty digesting it.
It is important, however, to note that some veterinary reports have shown that the main cause of allergies is peptides or glycoproteins, and grains cause less than 1.5% of all food allergy cases (Laflamme, 2014).
#2. High glycemic index:
A glycemic index measures the propensity of a specific food to raise an animal’s blood sugar level. The higher the index, the more likely it is for an animal’s blood sugar level to rise unhealthy.
Corn is a high-glycemic grain, which means that it can cause blood sugar spikes in some dogs. Corn is a high-glycemic grain, which means that it can cause blood sugar spikes in some dogs. This is especially true for dogs who are already diabetic or struggling with weight gain.
There is a myth that corn has a low glycemic index but that’s not true. Below are the glycemic index in different corn;
- Corn meal (69)
- Brown rice (55)
- Corn (53)
- Oatmeal (49)
- Wheat (41)
- Barley (25)
- Chicken (0)
- Beef (0)
#3. Not very digestible:
Many dogs have trouble digesting corn. It can lead to gas, bloating, and diarrhea.
Highly digestible starches rapidly increase plasma glucose and insulin. Corn is one of the least digestible starch sources for dogs. I
This means that a lot of the corn that your dog eats is not being used by its body and is instead passing through its system. The digestibility of corn relies on how it has been processed.
The kernel needs to be first refined into flour or into corn meal before it can then be cooked.
#4. Low biological value:
This means that corn does not provide all of the essential amino acids that a dog needs in order to grow and thrive. Corn has a significantly lower biological value when it comes to its protein utilization.
The biological value in dog food is determined by the levels of essential amino acids.
The minimum concentration of an amino acid that must be present in a food to be used by the animal for growth or maintenance is called its “essentiality.”
There are 11 essential amino acids that dogs need:
Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine
Arginine and cysteine are considered semi-essential because they can be synthesized by the body in limited amounts.
Taurine is not essential because dogs are able to synthesize it from cysteine and methionine.
The table shows a comparison of different dog food ingredients and their biological values. As you can see corn has a value of 54 while wheat glutten has 40. On the other hand, ingredients such as eggs and fish meal have 90+ biological value.
#5. Low mineral and vitamins content:
The Nutrient Balance Completeness Score(NBCS) tells you how complete the protein, fat, and carbohydrate in food are in relation to each other.
A score of 0 means that the food does not have any of the essential nutrients that a dog needs and a score of 100 means that the food has all of the essential nutrients that a dog needs.
The minimum nutrient balance completeness score for a food to be considered complete and balanced is 70.
NutritionData.com has information on nutrients of different crops analyzed from the USDA’s National Nutrient Database for Standard Reference. When i reviewed the nutritional profile of corn, I found it to have a very low NBCS score.
The table below shows the nutrient balance completeness scores of different ingredients used in dog food. As you can see, corn has a score of 34, a considerably low amount.
- Brown rice (33)
- Corn (34)
- Barley (36)
- Oats (43)
- Quinoa (45)
- Wheat (48)
- Potato (51)
- Peas (53)
- Sweet potato (55)
- Spinach (91)
#6. Poor source of energy:
Compared to protein and fat, corn is a very poor source of energy for dogs. When oxidized, corn has the lowest levels of carbs that can be turned into energy in the form of ATP.
This means that corn is not an efficient source of energy for dogs and they would need to eat a lot of it to get the same amount of energy that they would from protein or fat.
The table below shows the energy content of different ingredients used in dog food.
In terms of calories, you can see corn has a lower calorie content than other carbohydrates such as rice, wheat and potatoes.
Compared to lean beef and chicken, corn meal has almost half of the calories that its beef and chicken counterparts have.
- Corn (3.5 kcal/g)
- Corn meal(4kcal/g)
- Beef fat (7.3 kcal/g)
- Chicken (6.3 kcal/g)
What are the benefits of corn in dog food?
Corn is a good source of dietary fiber and it can help to promote healthy digestion. Additionally, corn provides essential vitamins and minerals that are necessary for a dog’s overall health.
Corn is a good source of many vitamins and minerals including vitamin C, thiamin, niacin, riboflavin, pantothenic acid, vitamin B6, folate, phosphorus, magnesium, iron, zinc.
Corn provides essential nutrients, including:
- Protein: Corn is a good source of protein, which is essential for building and maintaining muscle mass.
- Fat: Corn is a good source of fat, which is essential for energy production and healthy skin and coat.
- Fiber: Corn is a good source of fiber, which is important for digestive health.
- Vitamins and minerals: Corn is a good source of vitamins and minerals, including vitamin A, vitamin C, potassium, and magnesium.
- Corn is a relatively inexpensive ingredient in pet food, so it can help keep the cost of pet food down.
Is corn in dog food bad?
Yes, various academic research has shown that corn is not as digestible as other carbohydrates, such as rice and potatoes. It also high glycemic index and has low biological value. Corn is also not an efficient source of energy for dogs and they would need to eat a lot of it to get the same amount of energy that they would from protein or fat.
For these reasons, we recommend avoiding dog foods that contain corn as the primary ingredient.
What does this mean to you as a dog owner?
