Today, Dr. Ruscio is back with the latest research on carbohydrates and the gut, and during Part 2 of our discussion, we dive into: -Michael's take on the statement that "all carbs get converted to glucose so there is no such thing as bad carbs" and whether there is a consensus regarding the role of all carbs, good carbs, bad carbs, high carbs and low carbs...[8:11] -Why Michael doesn't like food allergy tests or use them much in his practice...[13:10] -The role of carbohydrates or carbohydrate avoidance when it comes to a digestive condition like IBS (gas, bloating, abdominal pain, constipation, lose stools)...[19:40, 21:45 & 32:10] -How the microbiota influences this and whether people with digestive conditions need to feed their healthy bacteria in order to feel better, and if so, how do they do that if they're eating low carb...[20:20 & 23:45] -Whether a low carb diet really damages your thyroid...[40:40] -The impact of artificial sweeteners on a low-carb diet and the truth about stevia...[56:15] -Whether you really need to run like the plague when a supplement or bar has, say, 10g or 20g of carbohydrates...[52:30] -The impact of a low-carbohydrate diet on testosterone levels...[64:30] -And much more!
