Stevia sweetener could be sweeter, healthier and eco-friendly substitute to sugar, finds a new study.
Natural sweeteners derived from stevia may produce as little as 10% of the greenhouse gas emissions of sugar while still providing the same level of sweetness, according to new research from the University of Surrey.
Is Stevia an Eco-friendly Sweetener?
Researchers conducted a Life Cycle Assessment on steviol glycosides extracted from stevia and found that the production of the sweetener caused less environmental impact across a wide range of markers, when compared to sugar. For example, it offers an opportunity to reduce land use or water consumption compared to the same level of sweetness as sugar.
Many non-nutritive sweeteners (NNS), like steviol glycosides, can reproduce the taste of sugar, without the associated health risks, such as tooth decay, obesity, or diabetes. They can do this because they are many times sweeter than sugar. For example, 4g of steviol glycosides provides the sweetness equivalent of 1,000g sugar, because it is perceived to be 250 times sweeter.
Are Natural Sweeteners Like Stevia More Sustainable?
Dr. James Suckling, lead author of the study working in the University of Surrey’s Centre for Environment and Sustainability, said:
“The use of steviol glycosides and similar natural products could be sweet news for the health of our planet. However, our study readily admits that much more work needs to be done to understand the health impacts of steviol glycosides and other non-nutritive sweeteners when consumed as part of a wider diet.”
