Nutrition Transition in Rural Tanzania and Kenya.

All three types of malnutrition - underweight, overweight and micronutrient deficiency - are experienced in countries undergoing a nutrition transition, and they can occur in parallel in one community or even one household. To combat this triple burden of malnutrition, a combination of different strategies will be necessary, including a focus on food-based strategies that promote the consumption of a wide range of foods across nutritionally distinct food groups. In addition to a literature review, data from our own nutrition studies in both Tanzania and Kenya are presented in this paper. The literature review revealed an average of 10% of children in urban areas of Kenya and Tanzania with overweight and obesity, which is an alarming trend, and it is suggested that interventions need to start not only at school but also with adolescent girls and pregnant women to target the '1,000-day window'. From own study data, dietary patterns were generated that included a 'purchase' pattern dominated by bought and processed foods, indicating a possible nutrition transition even in the rural areas of both countries. Vegetable and especially fruit consumption was low in both countries. In addition, in Kenya, study participants exceeded the suggested maximum level of sugar consumption per day, which will most likely contribute to increasing levels in overweight and obesity prevalence and other noncommunicable diseases in general. As sugar was mainly consumed in combination with black tea, next to eating habits, changing drinking habits is also an important part of the nutrition transition and needs to receive more attention. A 'healthy eating at school and at home strategy' is suggested, which needs the support of both schools and parents/caregivers. In general, to take countermeasures against the negative trends of nutrition transition, joint efforts from all players in the field - not only those in nutrition, health and medicine, but also those in education and agriculture - will be essential.
