We are all aware that too much of sugar can be a problem for people who are trying to maintain a healthy lifestyle and manage their weight.

All the above mentioned warnings may make for good headlines, but in reality, science does not back up such claims. In fact, the National Cancer Institute has mentioned in an online factsheet that studies by the FDA approved low calorie sweeteners have not demonstrated evidence of an association with cancer in humans. The US FDA has approved aspartame, sucralose, and six other low-calorie sweeteners for use in humans. These sweeteners have been classified under the Generally Recognized As Safe (GRAS) category, showing that there is no conclusive proof to establish negative side-effects of any low calorie sweeteners 2 used in Sugar Free. Furthermore, international bodies like European Food Safety Authority's (EFSA) rigorous review of all available scientific research on low calorie sweeteners has concluded that it's safe at the current level of exposure, implying that Sugar Free is safe for consumption.


According to Dr Monica Mahajan, Director of Internal Medicine at Max Healthcare, "For people who are diabetic or people you want to lose weight, sugar free supplements may actually be beneficial. The key ingredients of these sugar substitutes like aspartame, sucralose and stevia have all been approved by World Regulatory bodies like WHO & US FDA."

The toxicology studies takes years sometimes and even decades before reaching the conclusive safety evidence. In India, low calorie sweeteners like Sugar Free are regulated by FSSAI, which approves low calorie sweeteners based on their claims and recommended ADI.

Speaking on the safety of Low-Calorie Sweeteners Dr. Rebeca Lpez-Garca, Toxicology and regulations Expert, said,"We know that low-calorie sweeteners are safe because as food additives they have to go through an extensive evaluation to get legally approved. So even if each country has its own systems basically the protocols are the same. The evaluation starts with simple studies on molecules and moves to complex studies where their digestion, excretion, and effect on the body are studied. If at any point during the evaluation process the molecule shows a toxic effect, no further studies are conducted and the product never enters the market. Toxicology studies are conducted based on internationally approved protocols and sometimes take up to 20 years to complete. After completion of all studies, international or local authorities look into these petitions and also call for international data. After a profound analysis of all the data available, authorities come up with recommendations." 

Overall, consumers can be confident that, low calorie sweeteners like Sugar Free are safe components for their diet because of the thorough regulatory framework for their approval. They not only offer the taste of sweetness with fewer calories, but could also be one of the answers to effective weight reduction and is when consumed in safe, recommended quantities.

And, if you are worried about exceeding the Acceptable Daily Intake levels, note that they're too large in numbers and you are unlikely to exceed them.
