In the "Real Mississippi" podcast, Kyle Lin and Sam Smith dive into whether sugar-free products are healthier or not. They discuss how studies show that artificial sweeteners can raise the risk of heart problems and strokes, especially when people overdo it. They further mention that sugar-free products cost more and that big companies have used marketing and social media to make them seem healthier than they are. In the end, Kyle and Sam remind listeners that, just like with regular sugar, moderation is the real key to staying healthy.
