Erm, this isn't really a new thing. This just sounds like a rebranded glycemic index ~> www.glycemicindex.com

With regard to the glycemic index, I figured the results of this study would be similar as well, especially since the glycemic index is often used to explain to people what foods will make you hungry sooner rather than later.

However, if you look at the results of the Satiety Index, they are quite different from the glycemic index. The glycemic index measures how foods affect your blood glucose levels. Low GI foods affect it less (and presumably don't make you feel as hungry as quickly), whereas High GI foods cause a spike and then significant drop in blood glucose levels (and presumably, this sort of spike makes you hungry more quickly and helps contribute to diabetes, heart disease, etc).

If you look at the results, the Satiety Index says that peanuts are less satisfying than white bread, while peanuts have one of the lowest GI rankings and therefore don't make your blood glucose level increase significantly.

On the other hand, potatoes (especially baked potatoes) have higher GI rankings (and cause blood glucose spikes), while the Satiety Index says they are one of the foods best at keeping people from getting hungry.

I think the big different between the SI and the GI is that the Satiety Index is based much more on subjective factors ("Do I 'feel' hungry?"), rather than the scientific measure of just how eating the food affects your blood glucose levels.

Satiety index is not new, but satiety is hugely underestimated: how full does a food make you feel?

More suggestions like this I hope to publish in Grand Rounds (purportedly the best of the medical blogosphere)on 1/9/07: its topic is Food and Diet in Medicine---how can food be used for good in health care, not just disease-causing?

Submissions due 1/7/07: anyone can submit; SlashFood bloggers have a lot to say on this, and I'd like to publish bloggers from outside of medicine.

Seems to me the SI comes with a helping of subjectivity, what with the index being a measure of feelings of fullness. The GI meanwhile is based on measuring blood glucose levels for 2 hours after the food was consumed.
However, if a large enough sampling was taken for the Satiety Index then cross referencing that with the GI might turn up some interesting results peope could use for a filling and low glycemic diet plan.
