Suji (Semolina): Uses, Benefits, and Side Effects

Introduction

Suji is also known as semolina which is called rava in Indian households, is a by-product of durum wheat. Suji, also known as coarse middlings, is made from durum wheat, scientifically called Triticum durum, a cereal crop widely cultivated in the Mediterranean region. Suji is a versatile ingredient that can be used for breakfast, lunch, dinner, or snacks. It is particularly convenient on busy days as it can be cooked quickly into a variety of dishes. In Indian cuisine, suji is extensively used to prepare popular recipes such as rava dosa, upma, dhokla, and many others. Let’s explore some of the benefits of semolina (suji)¹.

Properties of Suji

Suji may possess the following properties³:   

• It may help improve heart function. 
• It may have anti-diabetic properties.  
• It may offer protection against cancer.  
• It may support digestive health.  
• It may help lower cholesterol levels. 
• It may act as an antioxidant.  

Potential Uses of Suji for Overall Health

Some of the potential uses of suji are described as follows:  

1. Potential Use of Suji to Improve Immunity 

Suji may have immunoregulatory properties (balancing the immune cell functions) that may help to build immunity. A constituent arabinoxylan, present in suji may also help in stimulating the immune system to fight against diseases. Further studies are required to assess the true effect of suji on the immune system in the human body³.

2. Potential Use of Suji for Diabetes 

Suji may have anti-diabetic properties due to the presence of a plant constituent, arabinoxylans. Consumption of suji may lower the blood sugar level rise after that meal. However, you must check your blood sugar level regularly and consult your doctor in case of high blood sugar levels instead of self-medicating³.  

3. Potential Use of Suji for Heart Health 

Suji may be used in the case of cardiovascular diseases to improve heart health. Tocopherol and phenols which are the plant constituents present in suji may reduce the risk of heart diseases. However, further studies are required to study the effect of suji on the human heart. Seek medical help immediately if you experience any symptoms related to heart disease³. 

4. Potential Use of Suji for Colon Cancer 

Suji is an important source of dietary fibre and consumption of dietary fibre may be associated with a reduced risk of colon cancer. However, further studies on animals and humans are required to check the effect of suji on reducing the risk of colon cancer. Cancer is a serious disease; therefore, so it is essential to seek proper medical treatment rather than attempting to self-medicate³.  

5. Potential Use of Suji for Digestive Health 

Suji is a good source of dietary fibre and it plays an important role in gastrointestinal function (function related to the stomach and intestine). Suji may help accelerate digestion and increase the faecal bulk, potentially supporting overall digestive health and promoting regular bowel movements. Further studies are required to check the effect of suji on the digestive health of humans. However, you must consult your doctor if you feel discomfort in your stomach^3,5.   

6. Potential Use of Suji for Cholesterol Control 

Suji may be used to control the cholesterol levels in the body, possibly due to a compound called arabinoxylans, which has antioxidant properties. However, further studies are required to check the activity of suji for controlling cholesterol. It is important to have your cholesterol levels checked regularly and to consult your doctor if you have high cholesterol^3,6.   

7. Potential Use of Suji as a Prebiotic 

The dietary component that encourages the development of healthy intestinal bacteria is known as prebiotics. Suji may have a prebiotic effect that supports gut health. This effect is thought to be linked to a component called arabinoxylans, which may help reduce the risk of several chronic diseases. The prebiotic properties of suji might promote easier bowel movements, support healthy intestinal function, and enhance immune response. However, further research is needed to fully evaluate the prebiotic effects of suji on the human body³.  

8. Potential Use of Suji as an Antioxidant 

Suji may possess antioxidant properties, primarily due to the presence of ferulic acid. It may help deactivate and eliminate harmful free radicals, which are linked to the development of various chronic diseases. This activity could enhance the function of enzymes responsible for the body’s antioxidant defence. However, further studies are needed to confirm the antioxidant effects of suji in humans³.  

Though studies show the benefits of suji in various conditions, these are insufficient. There is a need for further studies to establish the true extent of the benefits of suji on human health.  

Based on my experience, durum wheat, including its whole grains and whole-grain flour may possess antimicrobial properties. This is attributed to the presence of Azelaic Acid (AzA), a compound known for its antibacterial and anti-inflammatory effects. AzA is commonly used in the treatment of conditions such as acne vulgaris and rosacea, and its presence in durum wheat suggests it may play a role in the grain’s antimicrobial benefits⁹.

How to Use Suji?

Suji is a versatile ingredient that can be used in a variety of cuisines. It is commonly used to prepare traditional dishes such as idli, dosa, dhokla, upma, pasta, cakes and many more food items can be made from suji.  

You must consult a qualified doctor before taking suji regularly. Do not discontinue or replace an ongoing treatment of modern medicine with an ayurvedic/herbal preparation without consulting a qualified doctor.  

Side Effects of Suji

Since suji is made of durum wheat, it may trigger a wheat allergy in some individuals. Possible side effects of a wheat allergy include⁵:  

• May cause nausea and vomiting  
• May cause indigestion  
• May cause diarrhoea  
• May cause sneezing  
• May cause headaches  

Did you know that durum wheat, scientifically known as Triticum durum, is the second most cultivated species of wheat species after the common wheat? Interestingly, durum wheat is particularly rich in gluten and is considered the toughest among all wheat varieties⁸.

Precautions to Take with Suji

Consumption of suji may be a risk for those who are allergic and intolerant⁵.  

General precautions should be taken while having suji, as in any other general medicine. Pregnant women and lactating mothers should take special care. You must consult your doctor before having suji. Precautions should be taken before giving suji to the elderly or children. In such cases, you must have suji only if your doctor prescribes it.  

Interactions with Other Drugs

There is not enough evidence on the interaction of suji with other drugs. Further studies on the interaction of suji are required. Therefore, it is essential to consult your doctor if you are on any other medication before consuming suji.  

Conclusion

Suji is a nutritious and versatile ingredient with potential health benefits like improved digestion, heart health, and immunity. However, more research is needed to confirm these effects in humans. Individuals with wheat allergies or medical conditions should consult a doctor before regular consumption.
