Locust bean gum comes from the seeds of the carob tree. It is also known as carob gum. If you are hearing about this for the first time, it might sound strange. Why would someone eat gum? But as a matter of fact, it is edible. And no, it is not at all sticky or gooey. Instead, it is typically in the form of a white powder. The tropical carob tree is similar to the cacao plant from which you get chocolate. 

Locust bean gum acts as a natural thickener added to different types of packaged food. Many products like yoghurt, ice cream, or cream cheese contain this ingredient in small amounts, so the flavour is not disturbed. The locust bean gum has a sweet taste with a subtle chocolate flavour. Hence, the food industry uses locust bean gum as a natural food additive. 

If you are a vegan and are worried about whether to choose this or not, you have nothing to worry about because it is plant-based. In addition, it has its use in preparing non-dairy desserts and yoghurt. Apart from being tasty, it has other nutritional benefits. In addition, locust bean gum is also gluten-free.

Potential Health Benefits of Locust Bean Gum

There are a lot of health benefits when it comes to the consumption of locust bean gum. There are a few key benefits of why we should search for this thickener ingredient in the packed products. 

  • It is an entirely natural thickening agent. It gets directly extracted from the carob tree. At the same time, other thickening agents are synthetically produced and are full of chemicals.
  • It is a plant-based product. Locust bean gum is the perfect solution in a world where people are lactose intolerant and avoid consuming dairy products. 
  • It has no adverse reactions to other ingredients, making it perfect for use.

Other health benefits of locust gum bean are:

Improves Digestive Health

With the amount of fibre in locust bean gum, you might have realised that it would be good for digestion. For our digestive system, intake of fibre is essential. Dietary fibre is also present in many plant-based foods like oranges, beans, broccoli, avocados, and whole grain.

A study shows that locust bean juice or carob bean juice works as an effective alternative medicine for treating gastrointestinal disorders in adolescents and children. Drinking locust bean juice improves digestive health by rehydrating and decreasing the duration of diarrhoea. It contains pectin, the compound that helps treat diarrhoea. 

Helps Reducing Reflux in Infants

Reflux is a condition when babies spit out the liquid after reaching the stomach. As a result, the liquid is thrown out through the oesophagus, contributing to reflux or discomfort. Intake of locust bean seeds can reduce this discomfort.

But be very careful about the amount you feed them. Also, consult your paediatrician before trying this because your infant might be allergic to it. The locust bean seed helps thicken the liquid once it reaches the stomach. In addition, the thickness of the solution prevents vomiting of the fluid, reducing the reflux in babies.

Locust Bean Gum Manages Blood Sugar

The natural inositol in locust bean seeds regulates the blood sugar level in the human body. It can also reduce blood sugar by limiting the amount of sugar and carbs the body absorbs.

It has been researched and proved that this inositol sugar not only reduces blood sugar but also helps in improving insulin sensitivity. Interestingly, locust bean gum is an indigestible gel-forming complex carbohydrate. Therefore, it reduces the rate of gastric emptying, which lowers the postprandial serum glucose level. Further, a study states that locust bean gum might be helpful as an adjunct dietary treatment of diabetes mellitus in humans. 

Good for Weight Management

If you are on your weight loss journey and looking for healthy alternatives all the time, you don’t have to worry about eating locust bean gum. Instead, you can easily incorporate this into your daily diet because it is low in sugar and fat.

In addition, the presence of high fibre is also a contributing factor in weight loss.

Locust Bean Gum Controls Hyperlipidemia

A study shows that eating locust bean gum or products with locust bean gum appears to be a safe approach to controlling hyperlipidemia.

The results support using food products with locust bean gum to treat familial hypercholesterolemic children and adults. It regulates hyperlipidemia by reducing low-density lipoprotein cholesterol and improving HDL/LDL ratios. 

When to Avoid Locust Bean Gum

There are some cases where you need to avoid the consumption of locust bean gum. We must know in which cases It can prove to be harmful. Firstly, you need to be sure that you are not allergic to it before consumption.  If you are not sure about it, you can find out by an oral test with an allergist. It is possible that you may get one or the other breathing problem if you are allergic to the bean. If such a situation occurs, immediately contact your doctor, as it might sometimes become serious. However, revaluation research says few case reports of allergy to locust bean gum after oral intake is present. Most allergic reactions only come from occupational contact with locust bean gum.

Also, if you are allergic to locust bean seeds, you should avoid all kinds of carob-containing products. Although the U.S. Food and Drug Administration has generally recognised the locust bean seeds as safe, you need to stay cautious. For example, those with frequent occurrences of rhinitis and asthma might have to stay away from locust bean powder. Unfortunately, not enough studies are there to evaluate the safety of locust bean gum and its supplements during pregnancy and breastfeeding.
