I am increasingly approving of The Nutrition Diva

She is part of the Quick & Dirty Tips podcasting family. I enjoy several of those podcasts as a matter of fact.

What makes me point out The Nutrition Diva? She uses common sense. And science.

I like that.

For instance, I had fallen prey to high fructose hysteria (to my shame, as I now realize) and she helped shake me into common sense (emphasis added):
... As is so often the case, a little chemistry helps makes things a lot clearer. Table sugar, or sucrose, is actually made up of two types of sugar molecules; it’s about equal parts glucose and fructose.

Regular corn syrup, the kind that you can buy on the grocery store, has a different profile. It’s much lower in fructose than table sugar. You heard me correctly: Corn syrup is naturally quite low in fructose. And that makes it a poor substitute for table sugar. Things made with regular corn syrup don’t taste the same as things made with table sugar.

The breakthrough for food manufacturers came when they figured out how to produce a corn syrup that was higher in fructose. High-fructose corn syrup actually has about the same amount of fructose as regular table sugar—making it a viable alternative for food processing. Because corn syrup is so much cheaper than cane sugar, manufacturers quickly adopted it and high-fructose corn syrup has largely replaced cane sugar in manufactured foods.

But here’s what gets lost in the high-fructose hysteria: Foods and drinks made with high-fructose corn syrup are, in general, no higher in fructose than foods made with regular sugar. But they are cheaper. ...
Or this bit of information about how much water to drink? Now, this one I knew. But it was refreshing to hear a little known bit of information being brought to light through a venue that is fairly popular (or so I'd bet):
... I bet you’ve heard it said that you need to drink at least eight glasses of water a day in order to stay properly hydrated. Perhaps you’ve also read that by the time you feel thirsty you’re already in an advanced state of dehydration, or that most of us are chronically dehydrated. Chances are also good that you’ve been told that drinking caffeinated beverages like tea and coffee cause you to lose more fluid than you take in.

What would you say if I told you that all of these widely held truths are little more than urban legends?

I can almost hear your shocked expressions! The dehydration myth has become so firmly entrenched in our collective consciousness that it may indeed come as a surprise to learn that there is very little scientific support for any of these notions. ...

You don't have to listen to the podcast if you'd rather read. Full transcripts are available for each show.
