One of the major problems with fast-digesting carb sources is that they drive up blood glucose levels, which in turn causes the release of insulin. These two factors, individually and especially when combined, can lead to unhealthy weight gain.

To help remedy this problem, the obvious choice is to take white pasta, white rice, candy, and other simple sugar sources out of your diet. But what about the occasional slip-up? You know, when you fall "off the wagon" for a night or two and devour a Domino's pizza? In those instances, you may want to add some Thai "yellow" curry powder to your slices.

Why? Because a single serving of this Thai flavoring was found to slow the absorption of sugar into the bloodstream after consuming carb-rich foods, say researchers from Mahidol University in Thailand. As an added bonus, this same spice was found to reduce the risk of heart failure.
