To date, stevia or Stevia Rebaudiana is viewed as one of the best alternatives to sugar. However, the truth of the matter is that there have been conflicting results of studies concerning whether or not consuming stevia is beneficial.
Some studies point out that stevia indeed is not only a good alternative to sugar, but is also helpful in terms of weight loss since it doesn't contain any calories. However, there have also been studies that declared results showing that people tend to have higher levels of sugar upon eating food containing stevia. In fact, the US FDA has not given safety approval to stevia leaves; hence, they warn people from consuming them, as doing so may potentially worsen their health. Moreover, stevia can also potentially interact with anti-fungals, anti-inflammatory, anti-virals, fertility agents, and other medications.
