It is all about the number of colony-forming units and the strain.
You may want a mix of Lacto and bifidi with other types for different things, but most yoghurt has too low amount of bacteria. Bioavailability in PB capsules is more an issue about the integrity of your gut than the mere amount you can put per square, to say so.....
About 5 years ago, I attended a lecture with Dr Rindfleisch at University Wisc in gut-associated immune dysfunction. He spoke about something as simple as putting the baby to breast right away and the importance of vaginal birth for the proper formation of lactobacillus in the sterile gut. And this is evolving science and dynamic as nothing else. I have had Crohns patients on PICC lines for recurrent blood cloths due to infected pain pumps where surgery has not been very helpful. After 6 months of detox, the disease is being calmed down and after two more years of same they are entirely different. GI doctors used to say I was a quack, or at least suggest so, but word of mouth from patients is something the medical establishment have not found out how to regulate yet.
Cutting edge, integrative and low-risk healing science that is actively developing every day. Definitely a better alternative than steroids and hoping the flare doesn't need surgical resection.
The young physicians of today will have to become MUCH BETTER and MUCH SMARTER than us from the previous generation. Student loans was bad in my "previous life", but nothing like now!! At the same time, the fragmentation of healthcare remains the biggest threat to us overcoming lack of proper healthcare. If there was more respect and APPRECIATION of primary care doctors instead of lobbyist driven selective agendas mostly for pandering,it would be a huge start.
I am optimistic. For once, the millennial generation tends to be better at thinking themselves. For second, they are now being exposed to age-management, direct practice care and the flexibility you can have if you do not swallow he notion that you cannot have your own work. I have a primary care friend on of the major cities that made about 500 K last year and was working less than when he was family doctor for a multi-speciality group and no call.
His kids and my kids have met a couple of times and we both agree our family life is not comparable to how it was.
