Description

Artificial sweeteners offer us a delicious choice: the sweetness we love without the calories or the consequences. Do even the quickest online search and you’re hit with masses of conflicting information. Proponents say they are safe, they can help you lose weight and prevent diseases like diabetes. Critics say that they may cause a variety of health problems. GP and guest reporter, Dr Zeeshan Arain unpacks the science on artificial sweeteners and how they may impact or benefit our health. Fossil hunters want to know what life was like when dinosaurs became extinct 66 million years ago. We join an Aussie palaeontologist on a US expedition searching for dinosaur fossils in Antarctica, the most challenging place to explore the end of their ancient world.
