Stevia is a natural sweetener extracted from the Stevia rebaudiana plant, native to Brazil and Paraguay. It is a popular alternative to sugar due to its zero-calorie content and lack of carbohydrates, which prevents it from affecting blood sugar levels. However, there is ongoing debate about the safety of stevia, particularly concerning its impact on the liver, kidneys, and overall health. While some studies suggest that stevia extract can improve markers of fatty liver disease, others indicate potential negative effects, including increased cholesterol and liver enzyme levels. The effectiveness of stevia as a sugar alternative for those with fatty liver disease remains a subject of ongoing research.

What You'll Learn
Stevia extract may reduce markers of fatty liver disease
Stevia is a natural sweetener extracted from the Stevia rebaudiana plant, native to Brazil and Paraguay. Unlike sugar and most other sweeteners, it has zero calories and contains no carbohydrates, and therefore has no effect on blood sugar levels.
Stevia extract has been found to improve several markers of fatty liver disease, including overall levels of fat and scarring in the liver. These effects are independent of weight changes. A study led by Rohit Kohli, MBBS, MS, found that stevia extract may reduce markers of fatty liver disease. The pre-clinical research, published in the journal Scientific Reports, has led to a clinical trial that is currently in progress.
The study compared the effects of two non-caloric sweeteners, sucralose and stevia extract, on mice with a preclinical model of fatty liver disease. The researchers then compared the effects, finding that while sucralose had beneficial effects on the pancreas, stevia extract showed benefits for the liver.
The mechanisms underlying stevia's positive effects on the liver could involve reductions in cellular stress and changes to the bacterial community lining the gut. However, it is important to note that fully understanding the clinical relevance of these findings will require further research.
While stevia is generally considered safe for human consumption, some people have reported minor side effects such as bloating, nausea, dizziness, muscle pain, and numbness. It is always recommended to consume any sweetener, including stevia, in moderation.

Stevia is generally considered safe for human consumption
Stevia is a natural sweetener extracted from the plant Stevia rebaudiana, native to Brazil and Paraguay. Unlike sugar, it has zero calories and no carbohydrates, and therefore does not affect blood sugar levels. This is important because excess carbohydrates are converted by the liver into fat, which can lead to fatty liver disease.
Fatty liver disease, or nonalcoholic steatohepatitis, occurs when the liver is composed of more than 5% fat, and can lead to cirrhosis and liver cancer. While there is currently no cure for the condition, stevia extract has been found to improve several markers of the disease, including overall levels of fat and scarring in the liver. These effects are independent of changes in weight, and may be due to reductions in cellular stress and changes to the bacterial community lining the gut.
While stevia is considered safe, it is important to note that it should be consumed in moderation and not used as a replacement for simply switching from sugar. A balanced diet with proper exercise is crucial for maintaining health, and stevia should be used as an occasional sweetener when needed.

Sucralose vs stevia: which is better for fatty liver disease?
Sucralose and stevia are both non-caloric sweeteners that are widely used in a range of foods and drinks. Sucralose is an artificial sweetener, whereas stevia is a naturally occurring sweetener extracted from the stevia plant.
Sucralose
Sucralose has been found to have beneficial effects on the pancreas. However, studies on mice have shown that it does not have any benefits for the liver. In fact, some studies have shown that sucralose can cause severe damage to the liver and kidneys, with elevations in liver function enzymes observed after chronic consumption.
Stevia
Stevia, on the other hand, has been found to have potential benefits for people with fatty liver disease. Studies have shown that stevia extract can improve several markers of fatty liver disease, including overall levels of fat and scarring in the liver. Stevia has also been found to lower glucose levels and improve insulin sensitivity, indicating that it may help with blood sugar regulation. These effects were independent of changes in weight.
In conclusion, while both sucralose and stevia are approved by the FDA, stevia appears to be the better option for people with fatty liver disease. However, it is important to note that the long-term effects of both sweeteners are still not fully understood, and some studies have found potential negative effects of stevia on the liver, kidneys, and other body systems. As such, further research is needed to fully understand the safety and efficacy of these sweeteners in the context of fatty liver disease.

The potential negative effects of stevia on mice
Stevia is a natural, zero-calorie sugar substitute that is recognized as safe by the Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, some studies have suggested that stevia may have negative effects on mice, particularly when consumed in high doses over an extended period.
One study found that long-term administration of stevia to mice resulted in significantly increased cholesterol levels and decreased HDL (high-density lipoprotein) levels. Additionally, stevia administration was associated with a significant reduction in hemoglobin, hematocrit levels, and RBCs (red blood cell) count. Stevia also increased alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, which are liver enzymes that can indicate liver problems. These negative effects were observed in both male and female mice.
Another study, which investigated the effects of stevia on gut bacteria, found that stevia glycosides impaired the growth of certain beneficial bacteria, such as Lactobacillus reuteri, and disrupted communication between Gram-negative bacteria in the gut. This microbial imbalance could potentially lead to negative health consequences.
Furthermore, a study conducted by researchers from Children's Hospital Los Angeles found that replacing sugar with sweeteners like stevia in the diets of mice with a preclinical model of fatty liver disease did not show any beneficial effects on the liver. While stevia has been found to improve markers of fatty liver disease, this particular study did not find any liver-related benefits.
It is important to note that the negative effects of stevia observed in mice may not directly translate to humans. However, these studies highlight the need for further research and caution when consuming stevia or other sweeteners as a replacement for sugar.

Rebaudioside A: a potential treatment for fatty liver disease?
Non-alcoholic fatty liver disease (NAFLD) is a condition where the liver is made up of more than 5% fat. There is currently no cure for the condition, which can lead to cirrhosis and liver cancer. Risk factors for NAFLD include obesity and high sugar consumption.
A study by Dr Rohit Kohli compared the effects of two sweeteners, sucralose and stevia, on mice with a preclinical model of NAFLD. The study found that sucralose had beneficial effects on the pancreas, but no benefits for the liver. On the other hand, stevia extract improved several markers of NAFLD, including overall levels of fat and scarring in the liver, and these effects were independent of changes in weight.
Stevia is a natural sweetener extracted from the stevia plant. It is widely used in a range of foods and drinks as an alternative to sugar. While the use of artificial sweeteners has raised concerns regarding metabolic health, stevia is generally considered safe and/or not metabolized by the liver.
Rebaudioside A is a purified sweet-tasting component of stevia. In a study on mice with diet-induced obesity, rebaudioside A was found to significantly improve liver enzymes, hepatic steatosis, and hepatic fibrosis compared to fructose and sucrose. It also improved endoplasmic reticulum (ER) stress-related gene expressions, fasting glucose levels, insulin sensitivity, and restored pancreatic islet cell mass, neuronal innervation, and microbiome composition. These findings suggest that rebaudioside A may be a potential treatment for NAFLD, although further research is needed to fully understand its clinical relevance.
