A balanced diet is important for reducing hunger and malnutrition. Researchers thus advocate that small farmers in low- and middle-income countries should try to produce as many different foods as possible for their own consumption. However, a study is now questioning this recommendation to some extent. It suggests that good access to regional markets is more important than farmers growing a large diversity of crops on their own smallholding. Better-functioning markets increase the variety of foods available locally, which benefits the population as a whole.
