Some studies have suggested that high doses of stevia may lead to kidney damage, indicated by increased levels of kidney enzymes in the blood, which are markers of kidney injury. However, these findings have been observed at doses significantly higher than the average human consumption.
On the other hand, human studies have shown no significant adverse effects of stevia on kidney function. A notable study published in a reputable medical journal followed a group of healthy individuals and those with type 2 diabetes who consumed stevia regularly over a period of time. The results indicated that stevia did not negatively impact kidney function in either group. It’s crucial to note that the current evidence does not conclusively prove that stevia causes kidney damage in humans.
Evaluating the Safety of Stevia Consumption
The safety of stevia for general consumption has been a subject of thorough evaluation by health organizations worldwide. While some countries have set specific limits for its daily intake, others have based their recommendations on the available scientific evidence.
Daily Intake Recommendations
The acceptable daily intake (ADI) for stevia, as determined by the EFSA, is up to 0-4 milligrams per kilogram of body weight per day. This guideline is designed to ensure that stevia is consumed safely without posing a risk to human health. For the average adult, this translates to a maximum daily intake of about 12 milligrams of stevia, given an average weight of 70 kilograms. It’s worth noting that most products containing stevia are well within this safety limit.
Monitoring Health Effects
Despite the reassurances from regulatory bodies, it’s essential for consumers, especially those with pre-existing kidney issues, to monitor their health effects when consuming stevia. Regular check-ups with a healthcare provider can help in early detection of any potential kidney problems.
