Type 2 diabetes is a lifelong condition in which the level of sugar in the blood is too high.
It can be kept under control with medication, and by following a healthy diet – complications are more likely in people who are overweight.
While people with diabetes can still eat most types of food, including sugar, it is important to cut down on foods which could increase the risk of complications.
Dr Belma Malanda, senior project officer at the International Diabetes Federation, recommends the following five diets for people with diabetes.
A low-carb diet entails avoiding or cutting down on food containing sugar and foods with a high glycaemic index, such as pasta rice and bread.
These should be replaced with foods which are rich in protein, such as meat poultry, fish, eggs, cheese, nuts and seeds, and low-carb vegetables like salad greens, cucumber, broccoli and summer squash.
A Mediterranean diet is one which is abundant in plant-based foods such as fruits, vegetables, breads, other forms of cereals, beans, nuts and seeds.
Food is fresh, not processed, and olive oil is the principal source of dietary fat.
Dairy products are consumed in low to moderate amounts, while red meat and eggs are consumed at low frequency and amounts.
