Here's another one we've never thought of before. For better results, you can add a teaspoon of vinegar to your rice while the water is still boiling. The vinegar acts to break down a bit of the rice's starch, resulting in a more fluffy consistency. In addition, the rice will come out tasting a bit better. You'll be able to keep the rice longer since vinegar is an antibacterial.
However, that's not all it does. Vinegar has been shown to help lower the glycemic index of a lot of foods, including rice so that blood sugar levels stay down after you eat.
