No I do not eat any foods with artificial sweeteners in them as I have heard many times that these are very unhealthy.
I rarely use refined sugar anymore even! I now and have for some time, been using coconut sugar or agave syrup, and while they are still sugar if you are diabetic, they are at least natural and unrefined.
When baking I use dates or similar to make my recipes sweet and usually a bit of honey.
No. Artificial sweeteners are not good because they are usually sweeter than average sugar, and they do make you CRAVE more sugar. I used to use stevia, because it is all natural, but since I heard this, I don't use it any more. I gave all mine to my Dad. I have never had saccharin ever in my life, but it is hard to avoid completely, as it is in a lot of medicines. I try not to have any sweets at all, and have weaned myself off sugar, so I have no need for artificial sweeteners. Agave syrup is highly processed, according to what I have read, and is 1 1/2 times sweeter than average sugar, so you must use less. I think the best way to get around the sugar dilemma is to just not have it at all, at least that is what I have to do for MY optimal health. You can call it by lots of different names and substitutes, but in the end, it is still sugar, and for me, it is not allowed.
I don't add artificial sweeteners to my food or drinks, but I don't avoid buying foods that contain these (particularly in soft drinks and iced teas). Now that stevia is readily available, I choose products sweetened with this where possible as it is a natural product.
