Copper is one of the essential trace minerals that the body needs in small amounts, yet it plays a very big role in keeping us healthy.
This vital nutrient helps in the production of red blood cells, supports the immune system, aids brain development, and contributes to strong bones and connective tissues.
Because the body cannot produce copper on its own, we must get it from the foods we eat. A deficiency in copper can lead to anemia, fatigue, weak bones, and even problems with the nervous system.
Recommended Daily Intake (RDI) of Copper (NIH):
- Adults (men & women): 900 micrograms (µg) per day
- Pregnant women: 1,000 µg/day
- Breastfeeding women: 1,300 µg/day
- Children: 200–890 µg depending on age
Thankfully, Nigeria is blessed with many local foods that are naturally rich in copper. In this article, you will learn about 10 Nigerian foods that are excellent sources of copper, and how they can fit into your everyday diet.
10 Nigerian Foods That Are Rich in Copper
1. Egusi Seeds (Melon Seeds)
Egusi is a household name in Nigeria, especially because of the popular egusi soup.
Apart from being delicious, egusi seeds are loaded with minerals, particularly copper. 100 grams of egusi contains about 1.5–2.0 mg of copper, which is more than enough to meet your daily needs.
Adding egusi soup to your meals not only satisfies your taste buds but also boosts your copper intake.
2. Groundnuts (Peanuts)
Roasted or boiled groundnuts are a common snack across Nigeria.
They are affordable, tasty, and nutritious. Groundnuts provide about 1.1 mg of copper per 100 grams.
Whether you enjoy them plain, as groundnut paste, or in sauces, they are a reliable way to get this essential mineral.
3. Tiger Nuts (Aya)
Tiger nuts, known as aya in Hausa, are popular in the North and are often used to make the refreshing drink kunu aya.
They contain around 0.6–0.8 mg of copper per 100 grams.
Tiger nuts are also rich in fiber and healthy fats, making them a great snack for digestive and heart health.
4. Cashew Nuts
Nigeria is one of the largest producers of cashew nuts in Africa.
These nuts are not only tasty but also one of the richest sources of copper, providing about 1.9–2.2 mg per 100 grams.
Just a handful of cashews can meet your daily copper requirement, while also giving you healthy fats and protein.

Sesame seeds, locally called beniseed, are widely grown in Northern Nigeria and used in soups, snacks, and condiments.
They are packed with copper, offering about 1.5–1.8 mg per 100 grams.
Beniseed soup is not only nourishing but also a powerful source of minerals for the body.
6. African Locust Beans (Iru/Dawadawa)
Iru, also called dawadawa, is a traditional seasoning used in many Nigerian soups and stews.
Beyond its strong flavor, it provides about 0.9–1.0 mg of copper per 100 grams.

Drinking cocoa beverages or using cocoa powder in your recipes can significantly boost your copper intake.

Copper may be needed in small amounts, but its impact on health is huge. From boosting immunity to supporting red blood cell production, copper is a mineral you should not overlook.
