Abstract

Background/aims: Little information is available about the nutrition of people with diabetes from Africa. For the treatment and prevention of diabetes by nutrition, we have assessed the major local foods in a baseline study.

Methods: The staple foods and meal frequencies of 53 outpatients with type-2 diabetes were assessed in a 24-hour dietary recall based on a questionnaire at a diabetes clinic in northern Tanzania in November and December 1999. In addition, data on weight and height, casual blood glucose, urinary glucose and diabetes therapy were ascertained.

Results: 72% of the patients had a body mass index of > or =25 kg/m(2); 64% of patients had casual blood glucose levels of >7.8 mmol/l, 47% had >11.1 mmol/l, and most of them were treated by sulfonylureas or conventional insulin therapy. The test for urinary glucose highly correlated with the blood glucose values, and was positive in 59% of patients. 36% of the patients had < or =3 meals/day. The foods stated most frequently were stiff porridge, plantains, bread, rice, beef, milk, amaranth leaves, orange and sunflower oil. The main beverages were water, tea and milk.

Conclusions: The baseline data obtained enable more precise dietary assessment and emphasize the need to collect more data on local food consumption in areas where pharmacological diabetes treatment is limited.
