Circadian rhythms and artificial light and diet

Has anyone been interested in Dr Jack Kruse work- stuff about circadian rhythms and eating the food appropriate to your genetic environment., so if you have a genome from Ireland , where your specific body has adapted over many thousands of years to the food etc in a seasonal way. We now do things like eat food out of this adaptation - like eating a banana which never grew there, which the genome doesnt have the evolutionary adaptation for. this disrupts many things. he has a wonderful questioning approach - I find him challenging and stimulating- if worrying.
