Effect of diet treatment on serum cytokines. a Interleukin 1β b Interleukin 8 c Interleukin 10 and d Interleukin-4 levels were measured. Within diet treatment but between age, points or bars with different lowercase letters denote significant differences between ages but within diet treatment (P ≤ 0.05). Within age but between diet treatment, brackets with: # denotes a trend for a significant difference between diet treatment (0.05 < P ≤ 0.10); * denotes significant differences between diet treatments at P ≤ 0.05; *** denotes significant differences between diet treatments at P ≤ 0.001
