Let's put aside the debate between using 'artifical' sweeteners or not, and accept the fact that some people do and some people don't. I do. I cannot tolerate a lot of sugar in my diet - it's like crack to me or something, because it makes me crave more and more foods - not just sweet foods. So, I use artificial sweeteners - mainly Splenda - in coffee or tea, and in a few of the foods that I eat.
With Stevia being the latest sweetener to be approved for use by the FDA, I decided to check it out. Stevia is a naturally sweet plant native to Paraguay whose leaves are 30 times sweeter than sugar in its unprocessed form. When purified, it can be 250-300 times sweeter than sugar. SweetLeaf Stevia was one of the first zero calorie, zero glycemic index alternatives on the market.
I tried it in many different ways - I added it to coffee, Fage Fat Free Greek Yogurt, made lemonade, iced tea and even used it in a few recipes that called for sugar.I didn't detect any bitterness at all (which you can from the liquid supplements) and it's quite versatile since it can be used to cook with (unlike Splenda).
