The researchers then determined the diet of the two groups, and subsequently looked at differences between the groups.
These are foods that are prominent in the traditional Mediterranean diet, the diet that most food scientists believe is much healthier than the diet that most residents of rich countries have adopted.
"In light of the rising melanoma incidence worldwide, these associations warrant further investigation and, if confirmed, they might have important public health implications for the reduction of melanoma incidence through dietary modification."
Scientists almost always argue for further investigation, but in this case, the remark makes more sense than usual. This type of epidemiological research has often found interesting associations in the past, which in larger follow-up studies proved to be modest or non-existent.
