Tiger Nut 101 - The Health Benefits Of Tiger Nuts

Ok, most people in Nigeria grew up eating Tiger nuts and we even call it “aki-awusa” I think that’s the spelling, though in Eastern part of Nigerian language. The mallams or abokis as people like to call them always hawked these yellow nuts in a wheelbarrow around the streets of Onitsha, Enugu selling out one cup at a time. And it normally came out a few weeks to rainy season. At least I always remembered eating it around March. Tiger nuts has a lot of benefits that we do not even realize and I’m increasingly realizing that a lot more can be done with it apart from chewing and spitting it out or swallowing it for the fiber property. I made some tiger nut milk by blending the tiger nuts and squeezing the juices out of it the same way you would do with coconut. This could be used in many desserts as it would add a different level of flavor to it. There are a few benefits of tiger nuts that I know and you can find them as you read along.


Oxford dictionary defines tiger nut as "The small dried edible tuber of a kind of sedge".

The tiger nuts plant is an annual plant which grows up to 90 cm tall with solitary stems growing from tuber. The plant is reproduced by rhizomes, seeds and tubers. The stems are triangular in shape and have slender leaves about 3 to 10 mm wide. The seeds of the plant are quite unique with a cluster of flat, oval seeds surrounded by four leaves at 90 degrees to each other. They are about 5 to 30 mm long and are linear to narrowly elliptical with 8 to 35 florets. The color ranges from straw colored to gold-brown. They can produce a total of 2420 seeds per plant. The plant foliage is quite tough and is often mistaken as a grass.
Now, Tiger Nut is a nut belonging to the crop of the sedge family which is spread all over the world. It is present mostly in the Western and the Southern Europe, Madagascar, Africa, Indian Subcontinent and the Middle East. It has also become very common in many other regions including China, Hawaii, Ukraine, New Guinea, New South Wales and various oceanic islands.

The tiger nuts crop can be found as weed, crop or in the wild. There is evidence that it was cultivated in Egypt since the sixth millennium BC and many other countries like Yemen, Morocco, Pakistan, Iran, Iraq, Mexico, Chile, USA, Niger, Nigeria, Gambia and Mali.

Tiger nuts are quite healthy and help to prevent heart attacks, thrombosis and activation of blood circulation. They also prevent cancer due to the high content of soluble glucose. Some investigators have also found that they have the ability of reducing colon cancer. They have high fiber content and delicious taste which makes them ideal for healthy eating.
Some major health benefits of tiger nuts are described below:

1. High fiber content:

The tiger nuts have quite a high fiber content in them. They have higher fiber content than oats, cabbage, carrot, plums and Chia seeds. This fiber helps the organism to prevent constipation (4). It also acts as an appetite suppressant and helps to control body weight.

They have a higher amount of starch, good fiber content, a high fat content, rich in sodium, calcium, magnesium, phosphorous, iron, copper, manganese and zinc and also have a higher amount of vitamin C and E content. Many important amino acids and some B-complex vitamins are also present in tiger nuts. They are quite good for diabetics and can be consumed roasted, dried or raw (6).

4. Helps in regulating blood sugar levels:

One of the great health benefits of tiger nuts is that they are helpful in managing blood sugar levels. They have insoluble fiber in them which is quite helpful for diabetic patients.

Tiger nuts have a rich content of vitamin E in them. The Office of Dietary Supplements of the National Institute of Health suggests that Vitamin E belongs to a group of fat soluble compounds with unique antioxidant properties. Antioxidants protect the body from free radicals which are the molecules with unshared electron.
The unshared electron interacts with oxygen to create reactive oxygen species which is damaging to the body. Vitamin E also protects the body by stopping the development of reactive oxygen species. Research has proven that vitamin E has colorectal cancer prevention properties (9).

8. Healthy substitute for lactose intolerance:

The milk obtained from tiger nuts is quite a healthy substitute for people who can’t drink cow’s milk due to lactose intolerance. Tiger nut doesn’t have any lactose in it and can be eaten as a substitute of milk which has high content of calcium in it and helps in bone building and growth of children. The tiger nuts milk has the highest nutrition among all the non-milk substitutes (10).

9. Good source of magnesium:

The Office of Dietary Supplements suggests that magnesium is quite important for the normal functioning of the body because it carries out over 300 biometric reactions in the human body. Some previous studies have suggested that a 100 g of tiger nuts has about 13 to 17 percent of magnesium which promotes the normal nerve and muscle functioning, maintains blood pressure, maintains blood sugar levels, strengthens the bones and keep a person healthy (2, 11).

10. High iron content:

Vegan diets are more efficient when the iron intake isn’t diminished. When you add tiger nuts to your diet then your overall health becomes better because this vegetable root has high iron content in it.

These nuts are beneficial especially against colon cancer by feeding the friendly bacteria which are passed by other foods. The starch in tiger nuts also helps in proper digestive functioning and insulin sensitivity (12).

12. Starch resistant:

Tiger nuts are the best whole food source of a specific type of fiber known as resistant starch. The pleasant flavor and texture adds to it. Resistant starch is a beneficial pre-biotic which means that it feeds on the good bacteria in the digestive system.
Resistant starch has been a hot topic of debate in the health world and more research has shown the unique benefits of this plant fiber. For example, research has indicated that starch resistant is a powerful factor in preventing and treating diabetes and obesity. But one thing should be kept in mind that introducing starch resistant foods like tiger nuts in your diet may produce symptoms of a shift in gut flora. You should introduce tiger nuts slowly and observe if you experience any symptoms of gas or bloating. If you observe these symptoms then you need to slowly increase the tiger nuts in your daily diet starting at just one or two per day.

Protein also keeps us energetic throughout the day.
A 2007 conducted in the University of Ibadan in Ibadan, Nigeria was conducted in which the researchers discovered that tiger nuts are an excellent source of obtaining protein from plant matter (9.7%) which is almost equal to protein from whole wheat (9.8%) (13).

14. Boosting potassium in the body:

Tiger nuts have high potassium content in them and the University Of Maryland Medical Center states that it is an essential mineral which helps in the proper functioning of the cell and other body organs, particularly the heart. Potassium is quite essential for the body to maintain the regulation of muscle contraction, digestive functions and controlling blood pressure levels.

Tiger nuts provide protein, fiber, nutrients and other micro-nutrients to the body but they also have some side effects in the form of allergic reactions. They have the side effects similar to those faced by eating other nuts. Some major side effects of tiger nuts are specified below:

1. Skin reactions

The ‘Teens-health From Nemours’ states that the most common type of food allergy reactions is skin reaction. Some typical skin reactions include rash, swelling around the mouth and eye, itching, general redness and tingling sensation in the mouth. A common allergy caused by eating tiger nuts is known as angioedema. Some people also get canker sores which are small, painful mouth ulcers (14).

2. Respiratory reactions

Some typical allergic reactions affecting the digestive system include coughing, running nose and sneezing. The respiratory allergic reactions caused from nuts like tiger nuts can cause life threatening side effects. The swelling in throat can cause shortness of breath and a tight feeling in the throat; these symptoms require immediate treatment. The University of Chicago has reported that throat tightness is a common side effect in nut allergy by 53 percent. The shortness of breath is present in 41 percent and wheezing in 29 percent. Breathing or smelling the nuts usually doesn’t cause any allergic reactions but sometimes a rare reaction can occur (15).

3. Gastrointestinal problems

Nuts are high fiber foods which is a quality making them quite healthy. You should eat fiber to aid digestion. But stomach problems like bloating, diarrhea and gas can occur if you eat a lot of fiber. When you eat too many tiger nuts during one evening then you can remain in misery the next day. The National Institutes of Health suggests that adult should eat between 20 and 35 grams of fiber per day.

4. Increase in weight

Nuts have high fat content in them. But most of the fat in unsaturated and lowers calories; high fat means high calories. The Harvard Medical schools states that when you add tiger nuts to your diet then you should look for other healthy sources for lowering calories to counter this effect. This snack could increase your weight if you don’t do this.

A serious allergic reaction is known as anaphylaxis which can cause stomach collapse, low blood pressure and loss of consciousness. Death can also occur in case of lack of proper treatment. Experts recommend that people with nut allergies should keep epi-pen with them at all times which contains adrenaline. You should administer it as soon as the reaction starts.

6. Diverticular disease

People suffering with diverticulosis develop small sacs known as diverticula in the muscles of the intestine. There have been reports that tiger nuts don’t actually cause diverticula but there is a risk of developing this disease if eaten in large quantity.

How To Prepare Tiger Nuts

Tiger nuts are quite easy to make. They have a crunchy texture and a sweet flavor.They are quite pleasant to eat too. The method of making tiger nuts is described below:
