Why should you add Afang leaves to the list of vegetables that you eat? I will tell you but first let me introduce the vegetable to those who do not know it.

Know Your Foods

The Afang leaves is indigenous to Africa. It’s a popular vine that grows in the South of Nigeria and found easily in the market places. You can also find it in tropical rainforests of Cameroon, Gabon, Democratic Republic of Congo (DRC) and Angola.

In DRC it is called Mfumbwa, Longongia or Banvale depending on the local language. In Central African Republic, Gabon, Congo, Angola and even some parts of DRC, it is called Koko.

The leaves of the vine is simple known as Afang to the Efik/Ibibio people of Nigeria. Another common Nigerian name for Afang is Okazi.

Interestingly, there are two common species of Afang – Gnetum africanum and Gnetum bucholzianum. Both species are found in all the countries mentioned and it is hard to distinguish the two. For the Gnetum Africanum, there are about 5 varieties – Asutan, Oron, Ikom, Welw and Koko.

The leaves are evergreen and can be harvested all year round. It is interesting to note that Cameroon exports Afang leaves to Nigeria, Gabon and Congo.

Nutrition

Afang has a rich fibre content (28-37% of the leaves) and appreciable protein content (13-18%). Mineral content is also high (2-9%). Like most plant proteins, Protein in Afang is not complete but it contains many essential amino acids such as Isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. It also contains an array of non-essential amino acids. Combining Afang with other food groups with better protein profile (such as dried shrimps, beef and complementary plant proteins) will increase protein content and make it more available for use by the body.

The very green leaves have high levels of carotenoids and sterols which act as antioxidants in the body. Afang leaves also have quite many phytochemicals like saponins and flavonoids that promote health. Saponins, in particular, help to reduce serum lipids and fight atherogenesis. It should be noted that some varieties have lower levels of saponins.

The mineral content of Afang leaves vary across the varieties. E.g. ikom variety has more calcium and iron than the others while Asutan has more magnesium and zinc that the others.

Traditionally, Afang leaves are used to treat sore throats and enlarged liver in DRC. In Congo (Brazzaville), it is used to treat nausea and help soothe labor pains.

Because of its high fibre content, it can ease constipation and help with obesity and even diabetes.

Soups made from Afang are said to be rich in calcium but poor in iron. However, adding ingredients like the Uziza leaves and seeds, iru (locust beans) which contain some iron in addition to meat protein can go a long way to improve the iron profile.

While Afang leaves contain some antinutrients and toxic substances, the levels are well below the toxicity threshold (for hydrocyanic acid and oxalates). The raw leaves are said to be safe for human consumption, however, most of these antinutrients and toxins are destroyed or greatly reduced by cooking. Also, digestibility of the protein is better after cooking.

The Afang soup, which has become a delicacy in many local eateries and restaurants, is a great addition to your diet.
