Splenda (sucralose) is not a natural product. First, Splenda is a combination of sucralose and maltodextrin, a corn based bulking agent. There is a lot more maltodextrin in the product than sucralose. McNeil Nutritionals will not release the formula, my guess is that there is less than 10% sucralose (probably closer to 1%) in there. If you look at the crystals in your hand you can see both products. The maltodextrin is the fluffy, dull larger crystals and the sucralose is the small shiny ones.
Disclaimer! I sell sugar for a living to industrial food manufacturers :D I sell sugar and other ingredients including other sweeteners, mainly refined products like high fructose corn syrup.
Below is an article about a product called Shugr that is made from all natural ingredients.
The only "all natural" or "organic" sweetener product is called Organic evaporated cane juice. It is just what it says it is. Juice from organically grown cane plants that is evaporated to create a crystal. All other products out there are either chemically manufactured or "naturally" occuring sweeteners that are extracted from fruits.
http://biz.yahoo.com/bw/050212/125007_1.htmlPlease let me know if you would like more information on sugar, hfcs, sucralose and all alternative sweeteners. I have a ton of reference materials on all of them and would be happy to scan and email (or fax) to anyone interested! I have a whole library of information on just about any type of food ingredient we consume. The majority would be in sweeteners, wheat flour, corn products (dry and wet, including corn starch, dextrose, hfcs, corn syrup),modified food starches, vegetable oils and shortenings (don't get me started on trans fats!), milk products, salt and everything in between! I have a limited amount of information on food additives. Also feel free to ask me what something on an ingredient statement is and I will tell you or find out!
Remember, everything in moderation. The problem is Americans don't know the meaning of the word moderation.
