All of this may be a big surprise to those new to the world of natural health. Advertisements frequently pressure parents to use artificial sweeteners in cooking to keep their children healthy, and often depict scenes such as mothers baking while holding a young child. But it looks increasingly likely that the reality is that these sweeteners actually promote weight gain, rather than prevent it!

While skeptics would try to invalidate this study because rats were used instead of humans, the authors stated that it has already been demonstrated that T4 levels in rodents are a valid indication of thyroid function in humans. There is also the fact that poisoning humans is completely unethical. And if you do want human studies, one on 17 obese people showed that sucralose consumption negatively affects blood glucose and insulin levels. Therefore, long-term consumption may contribute to diabetes or insulin resistance, and this on top of any effects on thyroid function could be disastrous to your health. Overall, it's best to just reduce added sugar consumption, and eat fruit or small amounts of honey or stevia instead of toxic chemicals.
