News Flashes

Once again… if you have gut issues with grains, it’s usually more about “FODMAPs” than it is about gluten: "Gluten restriction in irritable bowel syndrome, yes or no?: a GRADE-assessed systematic review and meta-analysis"...06:01
Guess what? That expensive parasite cleansing system that you are using might have something called Mimosa pudica in it. Basically, this ingredient makes a bunch of long mucus threads wind up in the toilet (which look like rope worms, but aren’t): What Are Rope Worms? Are They Even Real?...14:47
How cardio might actually help you grow muscle: "Can cardio (eventually) make you bigger?"...22:24
There is "compelling theoretical evidence to suggest prolonged and repeated microdosing may cause valvular heart disease (VHD), and only weak survey evidence that it provides the benefits microdosers typically seek, such as enhanced cognition, or relief from depression and anxiety": "Safety First: Potential Heart Health Risks of Microdosing" — risk is particularly associated with repeated microdosing over several years, attributed to the strong binding affinity of microdoses like LSD or psilocybin to the serotonin 2B receptor (5-HT2B)...29:55
Why you're waking up at 3 am (and how to sleep through the night more consistently): "Why Do I Wake Up at 3 am?" — or, for a less scientific approach, here are all the “spiritual” reasons you might wake up at certain times during the night: "Spiritual Meaning of Waking Up at 1 AM, 2 AM, 3 AM, 4 AM, and 5 AM"...38:35

Mindsip insights from this episode:

Identify FODMAPs as IBS triggers, not gluten

For many people with irritable bowel syndrome, the issue is not gluten itself but fermentable compounds called FODMAPs, which are also found in wheat.

Try Dr. Davis's yogurt recipe for SIBO relief

Dr. William Davis has a specific yogurt recipe for SIBO using three probiotic strains fermented for 36 hours, which may provide relief when consumed daily for four weeks.

Understand 'rope worms' as intestinal mucus, not parasites

The long 'rope worms' seen after taking cleansing supplements with Mimosa pudica are most likely shedding intestinal mucus, not actual parasites, as DNA tests show they are 99% human.

Utilize Blood Flow Restriction training for superior muscle growth

Blood Flow Restriction (BFR) training is a more effective way than traditional cardio to build capillary density for muscle growth without the catabolic effects of endurance exercise.

Beware of microdosing risks to heart valves

Theoretical evidence suggests that prolonged microdosing of psychedelics like LSD and psilocybin could cause valvular heart disease due to their binding to the 5HT2B heart receptor.
