I wonder if the curtain will ever be completely pulled back on this, like on asbestos or tobacco. In the future, sugar may be relegated to a spice, like salt, pepper or MSG in percentage used in a person's diet. Fifty years down the road, a bunch of people mulling, "What were they thinking?" about our generation. not that sodium in processed foods doesn't need attention as well.
I think it has to eventually. I personally think we need to use people's A1C levels as a cost differentiator on healthcare premiums. Having a lower A1C is a major reduction in risk for type 2 diabetes and most heart conditions.
I had one library manager admit to me that it was a bit of a guild system: really, the only place you use the proprietary bits of a library science degree is in a library. If they hired anybody who showed proficiency in Dewey Decimal System, processing books and conservation, who would ever get a Master's Degree in it ever again? and of course, these are not a significant portion of the equation anymore.
