  • Other benefits of Ragi

Ragi for bones

Healthy bones are a necessity not only in growing children but also in adults. Among the plant foods, finger millet is the richest source calcium-containing approximately 300-350 mg per 100 g of grain. Additionally, ragi is also a natural source of vitamin D which is very important for maintaining bone health. A single case study in Indian villages suggests that regular consumption of ragi fulfills the daily recommended intake of calcium irrespective of the factors like gender and age. It was further suggested that finger millet consumption can be very useful in combating osteoporosis.

Ragi for weight loss

All cereals are a rich source of dietary carbohydrates, but finger millet has a relatively higher proportion of dietary fiber as compared to other cereals. Fiber-rich foods improve digestion and provide bulk to the food, making you feel full for a longer period. Ragi can thus be highly beneficial if one is looking to shed a few extra kilos. Observational studies show that with increased intake of calcium, there is more chance of weight loss and overcoming obesity. According to this study, high calcium intake can help lose weight by reducing the number of fat cells in the body.

Also, ragi contains an amino acid called Tryptophan (191 mg/g of protein – as per the Food and Agriculture Organisation (FAO) .1970a). This compound reduces appetite and helps to control diet.

Ragi for cholesterol

Numerous studies suggest that finger millet can help in reducing cholesterol levels in the body. Finger millets reduce the concentration of serum triglycerides bad cholesterol or LDL cholesterol. Also, fermented finger millets contain important metabolites like statin and dietary sterol which act as an enzyme inhibitors of the cholesterol passageway and help in reducing the serum LDL without affecting the HDL cholesterol levels.

According to an in vivo (animal-based) study, a multigrain diet can inhibit fat oxidation in the arteries thereby reducing the risk of problems like atherosclerosis and high blood pressure.

Ragi for diabetes

Diabetes is a metabolic and endocrine disorder characterized by the inefficiency of the body to take up the excess glucose from the blood. Due to dietary and lifestyle factors, there has been a massive increase in the number of diabetes cases over the years. The current line of treatment includes dietary modifications along with anti-diabetic medications.

However, with an increase in general awareness. there has been an increasing demand for foods that contain complex carbohydrates, high dietary fiber, and beneficial phytochemicals. This is because fiber-rich foods like ragi are a boon for diabetic patients since it takes longer to digest and hence glucose is released slowly into the blood.

The presence of excess free radicals is increasingly associated with the development of diabetes. In vivo studies suggest that finger millets control levels of blood glucose and oxidative stress in experimental diabetic models. Additionally, methanolic extract of ragi has been demonstrated to reduce the complication of diabetes by the free radical scavengers present in them.

Ragi as an antimicrobial

According to studies, the seed coat extracts of the finger millets show a high antimicrobial activity because of their high polyphenol content. The phenolic compounds contained in the outer layers of the finger millets may also restrict fungal invasion.

As per the study, finger millets possessed potent antimicrobial action against bacteria like Bacillus cereus and fungus like Aspergillus flavOU.

Ragi for healing wounds

The process of tissue repair in the wounded cells is generally associated with the onset of inflammation. Studies claim that an increase in the levels of reactive oxygen species (ROS) or free radicals slows down the wound-healing process in older people and in people who are suffering from chronic diseases. In vivo studies suggest that finger millet has antioxidant effects. This means that it can help scavenge the free radicals in the body and efficiently facilitate the wound-healing process.

However, no such study has been done on humans so far.

Ragi for anti-aging

It has been mentioned that finger millets contain antioxidant compounds like polyphenols which are very efficient in slowing down the aging process by scavenging the free radicals present in the body.

As we age, the collagen molecules in our body start to cross-link. Collagen is a natural protein responsible for providing elasticity to tissues. This Cross-linking makes the skin lose its elasticity and be easily prone to damage and age-related problems like wrinkles. It has also been associated with stiff blood vessels and an increased risk of some diseases like diabetes.

Studies suggest that finger millet and Kodo millet together can reduce the cross-linking of collagen thus impeding skin aging.

Ragi for cancer

According to research, antioxidants and phytochemicals exhibit anticarcinogenic properties. These compounds may suppress excessive cellular oxidation and protect the body against cancer. Ragi is rich in antioxidants. Seed coats of finger millets contain phenolic acid, tannins, and flavonoids which have effective antioxidant properties. Preclinical studies suggest that ferulic acid, the main component of bound phenolic acids present in ragi, has a suppressing effect on tongue cancer, colon cancer, and breast cancer cell lines.

Additionally, it has been reported that the nitriloside (vitamin B17) present in ragi can selectively kill cancer cells without harming normal body cells. However, more studies are still needed to understand the anticancer effects of ragi and its use in human anticancer therapies.

Ragi for anemia

Ragi is a natural source of iron. Regular consumption of ragi can thus be very beneficial for people suffering from iron deficiency or anemia.

A clinical study done on 60 young girls suggests that regular consumption of ragi can increase hemoglobin levels in the blood.

Other benefits of Ragi

Nearly 65% of the world’s population is lactose-intolerant which means that they cannot depend on dairy products for their calcium requirement. Ragi is the richest source of calcium and hence can easily prove to be an effective substitute for such people for their daily calcium requirements.

Ragi does not contain gluten. Thus, celiac patients should consume ragi. Ragi can be ground into flour which is easily digestible and does not require much cooking.

Diet plays a very important role in a lactating mother to produce enough milk to feed her baby. The diet must include nutrients like calcium, potassium, phosphorus, protein, iron, and vitamin C. Ragi is a powerhouse of nutrients. It is the richest source of calcium and thus, extremely beneficial for the lactating mother for increased milk production.

Ragi side effects

Ragi may cause kidney stone

Consumption of ragi more than the general levels should be avoided as it is high in calcium and may increase the level of oxalic acid present in the body. Patients suffering from kidney stones or urinary calculi are advised to avoid the use of finger millets as much as they can.

Ragi may cause thyroid

Goitrogen is a component present in millet that can interfere with the production of thyroid hormones and may inhibit the iodine uptake by the thyroid gland. Hence, patients suffering from thyroid should consult their doctor before consuming ragi.

Ragi may cause goiter 

The deficiency of iodine in the body may lead to goiter which is the development of an enlarged thyroid gland. Goiter may lead to symptoms like dry skin, anxiety, slow thinking, and depression. So, if you are suffering from goiter, it is best to avoid ragi.


Ragi is highly beneficial for health as it possesses great nutritional value and has a bunch of amazing nutrients including potassium and calcium. Also, it is high in antioxidants and amino acids. It can be used to fight against several disorders like diabetes and chronic diseases like cancer. It includes dietary fiber and polyphenols which help in fighting several health conditions like constipation, hypercholesterolemia, etc. Finger millet can be used as a food or a snack as it is considered to be health-building and therapeutic.

Ragi must be included in the diets of those who wish to lose weight as it contains zero cholesterol and is gluten-free. It is a natural product that possesses so many benefits. However, the number of benefits does not imply that it is suitable for consumption on a very frequent basis. Anything in excess may lead to side effects and ragi is no different. Every food item has a different effect on different people. It is recommended to consult a doctor before consuming anything beyond moderate levels as prevention is always better than cure.
