Kodo millet, scientifically known as Paspalum scrobiculatum, is an ancient millet grain cultivated in India since centuries. It is sometimes also referred to as kodra, kodon, arikelu, or varagu.
Kodo millet is a highly nutritious cereal grain indigenous to tropical regions of Africa and Asia. It remains an essential food crop in arid and semi-arid regions of India where rice and other grains do not grow well.
Compared to major cereal grains like rice and wheat, kodo millet is hardier and can withstand harsh weather conditions. It can be grown on marginal lands with little irrigation, making it an important crop for food security.
Some key benefits of kodo millet are:
- Rich in protein, fiber, minerals and vitamins
- Gluten-free and easy to digest
- Low glycemic index beneficial for diabetes
- Contains antioxidant polyphenols
- Grows well on low rainfall in hot climates
Let's look in more detail at the impressive nutritional profile of kodo millet and how to incorporate it into a healthy diet.
Nutritional Profile and Health Benefits
Kodo millet is packed with essential nutrients and bioactive compounds that provide many health benefits:
Protein Content
Kodo millet contains about 9-11% protein by weight, providing all essential amino acids. Compared to common cereal grains like rice, the protein content of kodo millet is substantially higher. The amino acid profile combined with B-vitamins like niacin make the protein easily digestible.
The high quality protein in kodo millet can complement plant-based diets by providing the amino acids needed for tissue repair and building lean muscle mass.
Dietary Fiber
A 100 gram serving of kodo millet provides about 6-8 grams of dietary fiber, which is a significant amount compared to other grains. The insoluble fiber helps regulate digestion and promotes gastrointestinal health. It also aids in weight management.
The high fiber keeps the digestive system functioning optimally. It adds bulk which creates satiety and reduces calorie intake. The fiber can also help lower cholesterol levels in the body.
Minerals and Vitamins
Kodo millet is a good source of several important vitamins and minerals that provide health benefits:
- Phosphorus - Supports bone health and kidney function
- Potassium - Regulates heart rate and blood pressure
- Magnesium - Prevent muscle cramps, migraines and inflammation
- Iron - Improves blood circulation and prevents anemia
- Zinc - Boosts immunity and required for DNA repair
- Calcium - Needed for bone development and strength
- Thiamin - Helps convert carbs to energy and supports nerves
The combination of B-vitamins, iron, calcium, zinc and other minerals make kodo millet helpful for maintaining the health and optimal function of various systems in the body.
Antioxidants
The phenolic compounds and antioxidants in kodo millet exhibit free radical scavenging activity which helps prevent diseases caused by oxidative stress such as cancer, neurodegenerative disorders, heart disease and accelerated aging.
Some antioxidants found in kodo millet include flavonoids, lignans, phenolic acids and plant sterols. The antioxidant content contributes to the anti-inflammatory and anti-diabetic properties of kodo millet.
Glycemic Index
Despite having high carbohydrate content, kodo millet has a low glycemic index. This helps avoid sharp increases in blood glucose levels. The slow release of sugar makes kodo millet suitable for diabetics to help maintain stable blood sugar levels.
The low glycemic impact also makes kodo millet beneficial for those looking to lose weight in a healthy way.
History and Origin
Kodo millet has a very long history of cultivation going back thousands of years. It originated in tropical western Africa and was brought to Asia between 3000 and 1000 BC.
In India, there is evidence that kodo millet has been cultivated since prehistoric times going back to 2500-1500 BC. Traditionally, kodo millet was grown in drier regions of the Deccan plateau in Southern India where rice could not thrive.
It has always been an essential coarse grain cereal crop for subsistence farmers in marginal farming areas due to its hardiness and ability to grown in dry zones with poor soils. Kodo millet could provide food security even during droughts when other crops failed.
Today it remains an important staple food grain in arid and semi-arid regions of India. Its resilience to harsh conditions also makes it an important crop for adapting agriculture to climate change.
Cultivation and Production
To understand the unique properties and uses of kodo millet, let’s look at how it is traditionally grown and harvested:
Climate Conditions
Kodo millet is a hardy grain able to withstand periods of drought, high temperatures and low soil fertility. It grows well in dryland areas receiving low annual rainfall between 400-600 mm. Temperatures between 27°C to 30°C are suitable during the growing period.
The ability of kodo millet to survive with minimal water and marginal soils, unlike rice paddy cultivation, demonstrates its resilience as a traditional food crop.
Plant Characteristics
Kodo millet is an erect annual grass that can reach heights up to 180 centimeters. It has long, drooping leaves and can be identified by its bristly, compact head inflorescence. The seed grains are small and covered with brown husk.
The stalks have a purple tinge towards maturity. The grain seeds are tiny and conical or elliptical in shape.
Harvesting Kodo Millet
Kodo millet traditionally requires minimal use of fertilizers and pesticides. The grains mature around 3-4 months after sowing. Harvest typically occurs manually using sickles when the peduncle turns yellow.
The seeds are then separated from the stalks, dried in sun and stored with husk intact to maintain freshness. In traditional farming, the stocks are fed to cattle after harvesting the grains.
Processing Methods
After harvest, kodo millet goes through some processing before it can be consumed:
Removing the husk - The indigestible husk covering the seed grains needs to be removed. This is done by pounding and milling which helps loosen and separate the husk.
Grinding - The huskless grains are ground between stone grinders into a fine flour. This traditional hand-pounding is slow but helps retain nutrients better. For commercial production, electrically-operated steel mills are used.
Separating the bran - After grinding, sieves help separate some of the coarse outer bran from the finer grain flour. The bran can be fed to livestock.
Polishing - Traditionally, the kodo millet flour was not polished further. But modern mechanical polishers can be used to get finer flour if needed. This may strip away more of the bran and germ.
Drying - The flour is dried in sunlight to reduce moisture content which prevents spoilage by microbes. Proper drying helps prolong shelf life.
Comparison to Other Grains
Compared to more widely consumed cereal grains, kodo millet possesses some nutritional advantages:
Protein - Kodo millet contains almost double the amount of protein compared to rice. The protein content is also higher compared to wheat and sorghum.
Essential amino acids - Kodo millet contains good amounts of lysine, methionine, tryptophan and threonine. Together they make the protein of kodo millet well-balanced.
Dietary fiber - The insoluble fiber in kodo millet is higher than in most grains. Only barnyard millet contains more fiber than kodo millet among the common millets.
Minerals - Kodo millet provides substantial amounts of minerals like calcium, magnesium, iron and zinc compared to rice and wheat. Only finger millet is superior in its mineral content.
Low glycemic impact - The glycemic index of kodo millet is lower than that of rice and on par with that of wheat and other millets. This helps manage blood glucose levels.
So kodo millet has marked nutritional advantages over the staple cereals rice and wheat that make up a large part of diets worldwide.
