Diets are like clothing fashion trends: they come into and out of style. And if you wait long enough: back into style again. One of my favourite pop culture research tools is Google Trends. Google Trends keeps a global finger on the pulse of what’s hot and what’s not in the world of nutrition and diets. And tracks this over time based on the popularity of search terms. Now a research team has mined this wealth of data to produce a snapshot of the ever-changing diet trends with some surprising results.
