Neverending story - artificial sweeteners newish studies

Hi I know you talked about it a lot already, but I have read about new-ish studies on several artificial sweeteners. The results were that some can change the gut biome, can increase cancer risk and can cause an increase in all cause mortality risk increased cancer risk.: https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1003950 gut biome https://www.cell.com/cell/fulltext/S0092-8674(22)00919-9 cardiovascular risk https://academic.oup.com/eurheartj/advance-article-abstract/doi/10.1093/eurheartj/ehae244/7683453?redirectedFrom=fulltext Is that new to you? Are these studies insufficient or might they make you re-evaluate your look on (some) artificial sweeteners. I'll just keep chugging my sweetened protein drinks until it is definitive because other risks in life are a lot more impactful, but I am interested in your take.

Exercise Related Fields

Hi, I was wondering if you could touch on the topic of exercise science fields in the same way that you did nutrition fields the other week? I'm currently in school working towards an exercise phys degree and it seems like the only job that earns any money is becoming a physical therapist. That's a lot more time and money to spend though!

How important is a mobility routine?

I currently do a lot of outdoor activities/sports (climbing, white water stuff, cycling etc) and lift twice a week. I’m in my 30’s now and and am seeing a limited range of movement compared to in my 20’s when I only did yoga 5 days a week. Will working in a mobility routine to my already busy and active life be worth it for my overall health? Where do I even start in building a routine and should I? I started following some mobility instagram people but not sure who actually has credentials and is worth it to follow?
