Table 1.

Absolute frequency of individual food samples regarding the convergent and divergent results.

Food Group	Food Samples (n)	Convergence/Divergence			Total
		fx1	fx2	fx3
Fruits	421	74	115	40	229
Vegetables	1020	93	104	116	313
Others	338	24	56	34	114
Total	1779	191	275	190	656

Note: fx1 = all articles converge in showing a significant difference for a particular parameter of a specific food; fx2 = all articles converge in showing no significant difference for a certain parameter of a specific food; and fx3 = all articles showed divergence in the significant difference for a certain parameter of a specific food.
