Cereals are a common and nutritious food group that provides various essential nutrients, including proteins. Proteins play a crucial role in the growth, repair, and maintenance of tissues in the body. In the context of cereals, there are three types of proteins to be aware of: complete proteins, incomplete proteins, and complementary proteins.
Complete proteins are those that contain all nine essential amino acids required by the body. They are considered high-quality proteins and are important for building and repairing tissues. In the case of cereals, certain varieties are complete proteins and can be an excellent source of essential amino acids.
Incomplete proteins, on the other hand, lack one or more essential amino acids. While they are still valuable sources of nutrients, it’s important to combine them with other protein sources to ensure a complete amino acid profile. Some cereals fall under this category and can be supplemented with other protein-rich foods to create a balanced meal.
Complementary proteins are a combination of two or more incomplete protein sources that, when eaten together, provide all essential amino acids. This means that by consuming a combination of different cereals or cereal with other protein-rich foods, you can obtain a complete protein profile.
Understanding the different types of proteins in cereals is valuable for individuals following vegetarian or plant-based diets, as cereals can serve as valuable sources of protein. By knowing the characteristics of each type of protein, you can create balanced and nutritionally complete meals that meet your daily protein needs.
Key takeaways:
- Complete proteins: Certain cereals contain all essential amino acids, making them complete proteins. Examples include quinoa and amaranth.
- Incomplete proteins: Other cereals lack certain essential amino acids and are considered incomplete proteins. Examples include rice and oats.
- Complementary proteins: Combining different cereals can create balanced protein sources by providing the missing amino acids. Examples include beans and corn or rice and beans.
Complete Proteins
Complete proteins are proteins that contain all nine essential amino acids, which are the building blocks of protein that our bodies cannot produce on their own. Including complete proteins in your diet is crucial for maintaining good health and supporting various bodily functions.
- Animal sources: Foods like meat, poultry, fish, eggs, and dairy products are considered excellent sources of complete proteins as they provide all essential amino acids.
- Plant-based sources: Some plant-based foods such as quinoa, buckwheat, soybeans, and chia seeds also serve as complete protein sources for vegetarians and vegans as they contain all nine essential amino acids.
Fact: Incorporating a variety of complete protein sources into your meals ensures that you meet your body’s protein needs and support optimal health.
What are Complete Proteins?
Complete proteins are proteins that contain all the essential amino acids needed by the body. What are Complete Proteins?

Incomplete Proteins
Incomplete proteins are protein sources that do not contain all the essential amino acids required for optimal health. However, when combined with other complementary proteins, they can still offer valuable nutrients. Grains, legumes, and nuts are some examples of foods that are considered incomplete proteins. To ensure a sufficient intake of all essential amino acids, it is crucial to include a variety of protein sources in your diet. Here’s a pro-tip: By pairing foods such as rice and beans or having peanut butter on whole wheat bread, you can create a complete protein meal.
What are Incomplete Proteins?
Incomplete proteins, also known as proteins that lack essential amino acids necessary for optimal body functioning, are commonly found in cereals. Having a good comprehension of what incomplete proteins are plays a vital role in maintaining a well-balanced diet. To ensure the consumption of all essential amino acids, incomplete proteins can be combined with other protein sources. For instance, when cereals are paired with legumes or nuts, a complete protein source can be created.
Sarah, who follows a vegetarian diet, had concerns about meeting her protein needs from plant-based sources. She discovered that cereals such as rice and wheat are incomplete proteins but can be made complete by incorporating them with beans or tofu. As a result, Sarah began including meals that consisted of rice and black beans or whole wheat bread with peanut butter. Not only did she find these cereal-based dishes delicious and nutritious, but she also experienced improved health and increased energy levels.
Examples of Cereals with Incomplete Proteins
Below are some examples of cereals that contain incomplete proteins:
| Rice |
| Corn |
| Wheat |
| Barley |
| Oats |
| Rye |
These cereals are considered to have incomplete proteins because they lack one or more essential amino acids required for optimal nutrition. However, you can make them complete sources of protein by combining them with complementary proteins like legumes or dairy products. For instance, if you pair rice with beans or add milk to your cereal, you can obtain all the necessary amino acids for a well-balanced diet.
