How international is the 30 plants a week diet?

"Plant points" or eating 30 different plants a week has become very popular in the UK recently. It is said to help with maintaining healthy gut bacteria, which in turn keeps you healthy and can aid with weight loss. Is this just a UK thing? Has anyone from other countries even heard of it? Many products in the UK even list how many plants are in different products now, very prominent "4 plant points". Is that happening anywhere else?
