I'm always vary of these articles in blogs that are clearly aimed at bringing traffic to someone's company. But this was a pretty curious analysis and a worthy read. I genuinely hope that #4 is going to be a trend for a while. Healthier diets are easier than ever these days and with more innovation and variety they'll just keep getting more accessible.
A side note, the cited "first 1000 days" diet and newborn brain development article in item #4 worth checking.
Is the bit on freelancer stats even ballpark accurate? If so, that's a major surprise to me.
