Soup thickeners are nothing new. Globally, they have been used for centuries to provide certain textures to our meals. Popular thickeners are corn flour, corn starch, cream, yogurt, white flour, blended rice and so on.

In Africa, using soup thickeners in cooking many African delicacies is a part of our food culture. In Nigeria, particularly in the South-eastern part of Nigeria, one of the most popular traditional soup thickeners is the Cocoyam (Ede) which is a starchy root.

However, there are a good number of traditional soup thickeners that are lesser-known and that offer much more than just providing texture to our foods. They also contain a lot of dietary fibre.  This is not surprising because they belong to the family of legumes (like beans) which are known for their high dietary fibre content.

Dietary fibre has beneficial effects on blood glucose and insulin levels in the body. They help to lower blood sugar as well as cholesterol levels. Diets high in dietary fibre reduce the risks of obesity and non-communicable diseases such as Diabetes Mellitus, heart diseases and cancer.

Dietary fibre helps to normalize bowel movement by adding bulk to stools thus preventing constipation. They also help in achieving a healthy weight.

These Traditional soup thickeners are:

Ukpo is the Igbo traditional name for the Horse eye beans, Mucuna Sloanei/Mucuna urens. It is also called Apon in Yoruba. The seeds are cracked, boiled, dehulled and ground to make powder as a soup thickener.

They contain a lot of antinutrients such as phytate, tannins, lectins, cyanogenic glycosides(that interfere with the digestion of protein and carbohydrates) but when cooked  (90 minutes) or toasted (60 minutes), these antinutrients reduce significantly. When not properly processed, it can interfere with the digestion of important nutrients.

Ukpo contains 51.1g of dietary fibre in 100g of edible portion.  It also includes 21.2g of protein, 17.8g of fat, and 7.5g of available carbohydrate. For micronutrient content, it has 14.2mg of iron, 3.3mg of zinc, 26.5mg of calcium and 271mg of phosphorus.

Apart from being used as a soup thickener, the leaves of the tree are used as animal feed in the north of Nigeria.
