I have recently been on a low carb diet, as I find that I can no longer tolerate even natural sugars like agave, honey, and dates. These raise the blood sugar which spikes the insulin, a hormone whose message is "store fat!" Insulin also causes the kidneys to retain water and therefore I would bloat from a high carb diet.  My dilemma is that I love sweets--and now it is not a problem, thanks to products like stevia, a natural plant that has safely been used in parts of the world as a sweetener for hundreds of years. It has no calories and no impact on the blood sugar (although for some people there might be a bit, as the brain is tricked into thinking it is getting sugar). Stevia used to be legal in the USA only as a cosmetic product because of politics: companies that made low calorie sweeteners such as aspartame did not want competition. Yet, aspartame gave me headaches and even sometimes symptoms of multiple sclerosis. So I would use stevia at times, but the aftertaste was bad--and to be honest, I wasn't too crazy about the "during taste" either.  Then I tried NuNaturals. This product is awesome and like no other stevia I have tried. It is not only delicious but also has no aftertaste (unless you put in way too much--a common mistake by people new to this). It comes in tablets and in powdered form (in a bottle or handy packets with individual servings). It also comes in alcohol-free liquid form and even in vanilla flavor. Unlike aspartame (which becomes even more toxic when heated) stevia can be used in baking. NuNaturals has a stevia baking blend just for that. (Since I am a raw fooder, I can't tell you how it tastes, but I am sure it is good, judging by their other products.)  Thanks to these great products, I can do a low carb raw diet but not be deprived of my sweets!

I have had Green Mountain coffee before, but had not tried the French Roast.  I am just realizing that there is a taste difference between different manufacturers, even with the same types of roasts.  The Green Mountain French Roast has the flavor I like and was expecting.  The price was reasonable and my order shipped quickly.  My only disappointment was in the shipping packaging.  I knew that I was ordering 2 boxes of K-cups but was surprised to see how big the shipping box was.  There was room for 3 boxes, with the extra space filled with bubble-wrap, which seems wasteful to me.  But on the whole, I am very happy with my coffee!

Ex Output:
Positive

Disappointed.  The big boxes had a very different flavor than the smaller boxes.  I am not sure why but not good.
