I'm guessing that she'll reference a new study that shows that *rats* consuming saccharin (
and old school artificial sweetener that's been linked to other risks, like cancer) get even fatter than rats eating plain old sugar (glucose in this case, not sucrose, aka table sugar).
Here's an LA Times write up on this.
I'm a big nutrition/physiology buff, and I have some thoughts here (I'm also a former chubsy as some of you know).
First, the study was done using rats. While rats can provide useful information, we need to be careful extrapolating these results to humans, especially in this case. After all,
artificial sweeteners and humans seem to provide mixed results.
Also, I'm glad it was pointed out that animals consuming diet products seemed to compensate by eating more. There very well may be some physiological (and psychological for that matter WRT humans) component to this, likely related to insulin.
But with that said, humans can consciously count and control their calories. I'd like to see some research where human subjects consumed *the same amount of calories* over a period of time while one group consumed products containing artificial sweeteners. Those results would be much more relevant.
Granted, the average person doesn't pay much attention to what they eat (and therefore they might compensate for drinking Diet Coke by eating more) but for a dieter who does pay attention, someone suggesting that they'd be better off consuming hundreds of additional calories a day in the form of
high fructose corn syrup (the main sugar in regular soda) is absolutely ridiculous IMO.
So what do I take away from this latest rat research?
1)-Stay away from Saccharin. True, researchers believe other more modern sweeteners are likely to have the same effect, but there's less cancer risk (although I'd point out that's pretty damn low already unless you have a saccharin IV drip going all day, every day) and the fact is that hasn't been proven to be the case yet.
Besides, who the hell still drinks original Diet Coke or Pepsi?! My God, is this 1988 or 2008? I hope these people realize that
drinks made with more modern sweeteners like Splenda (Coke Zero, Pepsi One, new Diet Rite, etc.) taste a LOT more like the real thing. I've even fooled die-heard regular Coke drinkers using Coke Zero/Cherry Coke Zero!
2)-All things in moderation. If you're currently drinking Diet Coke all day, every day, mix in water, tea (
both green and black since they provide different benefits) and even coffee (
which might reduce the risk of certain neurodegenerative diseases).
3)-Try only drinking diet soda *with* meals. Why? Well, if part of the physiological problem is related to an insulin burst (along with no/low calories), I would speculate that this would become less of an issue if you ate enough calories along with the artificial sweetener (the insulin produced could then be used to store the consumed calories). A small snack is better than nothing, but an actual meal is likely needed to really blunt the potential negative effects.
In the end, I wouldn't go and throw out all of your diet beverages and foods, at least not yet.
