Proven Benefits And Side Effects Of Kola Nuts

Kola nut is the fruit of the kola tree which is native to West Africa. In an average star-shaped fruit, about 2–5 nuts will be present. Although they have a bitter taste when freshly plucked, drying in the sun makes them taste milder with time. It contains about 2–3 percent caffeine and 1–2 percent theobromine, both of which have psychostimulating properties.

It also has minerals like potassium, magnesium, and calcium which makes it quite beneficial for human consumption. It shouldn’t be confused with bitter kola, the nut from the flowering plant Garcinia kola, that has several healing abilities. Kola nuts are also unrelated to gotu kola which is a medicinal herb used in Chinese and Indian medicine.

Side Effects Of Kola Nuts

Knowing both pros and cons of any food item is crucial before you start eating it. Not all exotic foods might suit your health status and you would have to be super careful about consuming them. Researchers have found that despite being healthy, kola nuts have a fair share of side effects too. These include the following:


1. Promotes Hypertension

Excessive Consumption Can Make You Sick

A study was conducted between two groups of people. One group consisted of people who had malaria and the other group of individuals was free from malaria right from the beginning of the study. Both were given 35 grams of kola nuts in powdered form for 4 consecutive days.5


Blood samples collected after four days showed an increase in malarial parasite density among the infected individuals. While the other group of individuals who were free from malaria showed signs of fever, dizziness, and weakness. Therefore, excessive intake can weaken your immune system’s actions leading to signs of illness. If you are on antimalarial medication, avoid kola nuts in particular as they can inhibit the drug’s effectiveness.

3. You Could Be Allergic To It
