Description of intervention(s) / exposure
A randomized cross-over trial compared the effects of a standard test meal either containing or not containing chilli puree in the context of a chilli-supplemented or chilli-free diet. Each background diet period lasted for 30 days, taken in random order. A chilli-free test meal was administered at day 26 of the chilli-free diet, a chilli-containing test meal at day 30 of the chilli-free diet, and a chilli-containing test meal at day 30 of the chilli-supplemented diet.
