What is a diet?

Many people hear the word “diet” and think it’s just about losing weight. But diet simply means the food and drinks we consume regularly. What we eat affects our health, energy levels, and even how long we live. A good diet can help children grow strong, prevent diseases like diabetes and high blood pressure, and help adults stay active and healthy.

In Africa, where food choices are often influenced by culture, availability, and economic factors, it is important to make informed decisions about what we eat. With many Africans experiencing health issues linked to poor diets, such as obesity, malnutrition, and heart diseases, knowing about different diets can help us live better lives.

How common are diet-related health issues in Africa?

  • Obesity: Studies show that obesity rates in Africa are rising, especially in urban areas. In Ghana, for example, nearly 43% of adults are overweight or obese.
  • Malnutrition: While some people eat too much unhealthy food, others don’t get enough nutrients. In Nigeria, 37% of children under five suffer from malnutrition.
  • Diabetes and hypertension: These diseases are becoming more common due to poor diets. In South Africa, 1 in 4 adults has high blood pressure, partly due to high salt intake.

By choosing healthier foods, we can prevent many of these diseases and live healthier lives.
