In the paper of Guesnet et al. [
[1]
] in the present issue, the interaction between omega-6 and omega-3 fatty acids are
illustrated in a thought-provoking way. It adds to the increasing evidence of a relation
between the changes of this ratio in human and animal diets and the global epidemics
of increases of metabolic complications as obesity, diabetes and neurological diseases.
A recent paper analyzing the plurality of the obesity epidemics, Klimentidis et al.
[
[2]
] express their concern about that also primates, domestic and feral animals are developing
obesity and furthermore that a similar trend is observed in laboratory animals. The
interesting fact is that neither the fat content of the chow or the fat intake of
the human population has increased over the latest decades [
[3]
], so other environmental causes are probably involved. In the humans special interest
has been focused on less physical activity depending on the technical development
worldwide, but this alone cannot explain the obesity epidemics, which also involve
infants and the population in developing countries [
[2]
]. It is certainly less likely in laboratory animals, whose living conditions have
been rather the same for many decades.To read this article in full you will need to make a payment
