Surely don't all supermarkets sell potatoes, carrots, green vegetables, fruit, nuts, minimally processed cereals (husk removal and cleaning), fresh meat, fish, cheese, eggs and dairy products including naturally processed cheeses?

I wonder if the term 'micromanaging [their diet]' is a touch perjorative. Given the prevalence of serious chronic diseases which are reported to be strongly linked to what you eat, shouldn't everyone be encouraged to take a serious look at how to 'macro' manage their diet, an action which is almost certainly likely to improve quality of life and maybe life span?
