Ben-Gurion University of the Negev Researchers (BGU) have found for the first time that cigarette smoke toxicity impacts the protective biofilm in the lungs, particularly concerning when paired with COVID-19 respiratory issues.
The experiment proved that the filter is a crucial element in reducing the harm of smoking so therefore, new filters need to be developed to reduce toxicity, explains Prof. Robert Marks, head of the BGU Avram and Stella Goldstein-Goren Department of Biotechnology Engineering. Prof. Robert Marks is a leading expert in the study of genetically engineered bacteria. His work focuses on finding the specific mechanisms of toxins in a variety of materials and their impact on the environment.
Natural Sweetener Safety
Due to the potential of artificial sweeteners to cause harm to our health, alternative food additives that are natural rather than artificial, low or no calorie, and sweet tasting have been the focus. In fact, one natural alternative to artificial sweeteners and sugar is the popular natural sweetener stevia. Stevia it turns out, is 100-to-300 times sweeter than regular table sugar; and, has no calories or carbohydrates. A boon for the dieting industry and dieters who follow the low to no-carb keto diet.
Stevia is a natural sweetener and sugar substitute derived from the leaves of the plant species Stevia rebaudiana, native to Brazil and Paraguay, that has been used for many years to sweeten tea and other beverages by several non-Western cultures. Aside from its non-caloric sweet taste in beverages, stevia has proven to be a good sugar substitute due to its active compounds (steviol glycosides) which are both heat-stable and pH-stable making it adaptable for
Is the sugar substitute stevia bad for our health?

People use sugar substitutes as a way to reduce their sugar intake. Excess sugar consumption can cause weight gain, lead to diabetes, and contribute to inflammation in the body.
For this reason, researchers have worked to find the perfect replacement that tastes like real sugar and is safe to consume.
Scientists have considered stevia a safe sugar alternative for years, but a new study raises the question of whether it can be harmful to gut health.
