Most people safely consume sweeteners within recommended levels. However, some studies point to possible negative consequences of their use.
Research and suspicion
Animal studies have shown a link between the consumption of artificial sweeteners and the development of various types of cancer. For example, a study published in Nature in 2014 found that mice consuming the sweetener sucralose were more likely to develop leukemia. There have also been studies on rats that show a link between consumption of the sweetener saccharin and the development of bladder cancer.
However, these studies were conducted on animals, and the results may not always be applicable to humans. Studies in humans have also yielded conflicting results. Some studies have found no link between sweetener intake and cancer, while other studies suggest a possible link.
Effects on the microbiome
One of the main reasons for concern about sweeteners has to do with their effect on the microbiome, the collection of microorganisms that inhabit our bodies. The microbiome plays an important role in our health, including digestion and the immune system. Studies have shown that some sweeteners can change the composition and diversity of the microbiome, which can have long-term health consequences.
For example, a study published in Nature in 2014 found that consumption of the sweetener sucralose in mice leads to changes in microbiome composition, as well as elevated blood glucose levels and insulin resistance.
However, it is important to note that these studies were conducted on animals, and the results may not always be applicable to humans. Studies in humans have also yielded conflicting results. Some studies have found no link between sweeteners and changes in the microbiome, while other studies suggest possible changes.
Professor Gunther Kunle, professor of nutrition and food science at the University of Reading, notes that sweeteners can be beneficial for people living with diabetes because they do not affect blood sugar levels. However, he also notes that sweeteners cannot completely replace sugar in some foods, such as jams or cakes.
Professor Kunle also notes that while sweeteners have been found to be safe at approved levels, there is insufficient data on their safety at higher levels. Therefore, lack of evidence does not equate to proof of their safety.
Recommendations for consumption
The debate over safe levels of sweetener consumption continues. In the U.S., the safe daily intake of aspartame is 50 mg per kg of body weight, and in the UK it is 40 mg per kg. But even with these recommendations, it’s important to remember that each person is unique, and their reaction to sweeteners can be individual.
In conclusion, the debate over the safety of artificial sweeteners continues. And while some studies point to possible negative effects of their use, other studies have found no link between sweeteners and disease. It’s important to remember that each person is unique, and their reaction to sweeteners can be individual.
