Most conventional nutritional health 'wisdom' is really false. Margarine is not better than butter. In fact margarine should never be eaten. We really aren't smarter than God. Our bodies need good saturated fat.
Truvia is not good for you. Please go to the link in the title of this post. There is a lot of information there and testimonies of bad side effects. This is from that link:
According to scientists who analyzed Truvia, it is 9/10 of 1% Rebiana and masking agent. It should be said that Rebiana is not an ingredient in the stevia plant, nor is it found in nature. It is produced by the action of chemicals and stringent alcohols on various stevia glycosides. Rebiana is simply the trade name Cargill gave their chemically derived product in 2008. The FDA “No Questions” letter states that Rebiana contains residues of ethanol and methanol. Rebiana is commonly confused with Rebaudioside-A (Reb-A). Reb-A is one of the 11 glycoside compounds naturally within the stevia leaf and is about 400 times sweeter than sugar. It is produced by the action of sunlight on the leaves. The other 99.1% of Truvia is erythritol, a sugar extracted from corn with alcohol(a sugar alcohol), which can be hard on the digestive system. Cargill has admitted that 30% of their corn is genetically modified organisms (GMOs). Truvia is essentially corn sugar, and is not really a stevia product.
But Truvia is not alone in their deception. PureVia is 8/10 of 1% Rebiana (even though they list it as Reb-A on their ingredients list) and 99.2% sugars, Sun Crystals is 96.5% table sugar, and Stevia in the Raw is 95.8% table sugar. All these “stevia products” are really just sugar products as well. Usually, when someone buys a “stevia product” they think they’re are getting a sugar substitute, but what they are really getting, at least with these products, are mainly just different forms of sugar, (and in a couple cases, mainly table sugar) at best.
I do use SweetLeaf Stevia. They are the only ones to use only pure water during the entire extraction process ( as opposed to chemicals and alcohols like other stevia companies), so the natural tase of leaf remains as well as the nutrients–at least in their dark liquids. I also use their powder, which has added inulin fiber, which feeds the good bacteria in the intestines, which in turn, strengthens the immune system. All forms of SweetLeaf Stevia retain stevia’s natural 0 calorie, 0 carb, and 0 glycemic index properties–I understand the only stevia product to retain all three of these properties.
