I miss you walking on your treadmill! Does not cause motion sickness lol please inspire us again, those who work from home to keep using our desk treadmills while working!

[sectionalsofa]

Dr Greger's response to the first question regarding sleep made my day... .and I have a fairly long day due to insomnia.

[ginnydoane]

Dear Dr Gregor, Get back on your treadmill. This is ridiculous. People don’t have to watch you. They can just listen. You are modeling good health. Love you. My life is so much better because of you.

[Rickalicious]

Dr. Greger is best! From sunny South Africa, thanks for all that you do!

[elizagal]

Feel free to deliver in any fashion you desire. People don’t have to watch or comment on your appearance. Us 99.99% love you just the way you are. You grandmothers heart must be as big as Texas 💚💜

I find the earlier I finish eating and the healthier it is, the better sleep I get. I ate poorly on Sunday and stopped eating around 7 pm. Got eight hours of sleep, but not much deep sleep according to Apple Watch. On Monday, ate very well and stopped eating at 2:30 pm. Got six hours of sleep and 1.5 hours was deep sleep and woke up without an alarm.

[JudeMaui]

Walking on my treadmill. Everyone should be on a treadmill while watching to help prevent vertigo or hey don’t watch and just listen.🌺

2:23 -> "Analyses of the ingredients and finished baked goods showed that spermidine is heat-sensitive, contrary to an earlier published statement [16]. In the present case, the quotient is about 3.4 between spermidine used (roll A: 149.4 mg/kg; roll B: 98.8 mg/kg) and the concentration in the finished baked goods (roll A: 47.1 mg/kg; roll B: 26.5 mg/kg)"

[sheralschowe]

[MegaGoddessofLove]

Good luck on your move! I actually have family in Vancouver. Oh also that's so cool about the gym in your apartment building. Great job going for a workout! 😊

[dmb]

In Arabia, the word hummus means chickpea. Whereas in other languages hummus is a dip made of chickpeas. Thus the confusion in one of the questions

[jeromespearman]

Thankyou for the time you give to reviewing the research and presenting it so clearly. Have you done any review of Hydrogen therapy ? And more specifically, Hydrogen therapy for cancer.

[JosephNJ]

Fiber Fueled, both books have a ton of info on gut health.

[Hanna-vqsb]

About the new study about risks of xylitol: the amounts consumed in the study were huge compared to the amount you get from a few xylitol chewing gums daily, and xylitol has in several studies been shown to protect teeth when chewn right after meal.

[BusyLizzy_]

Welcome to Canada! Are you coming to stay, or just as part of the tour?

[ramonocasio]

Glycine really help deep sleep, need to find research on this Dr. Greger

[KJSvitko]

Daily exercise is key to as healthy life. Ride a bicycleto school, work or for fun.
Riding a bicycle is a great way to exercise. Ebikes are bringing many older adults back to cycling.
Cities need to do more to encourage people to ride bicycles. Safe protected bike lanes and trails are needed so adults and children can ride safely. Speak up for bicycles in your community. Bicycles make life and cities better. Ask your local transportation planner and elected officials to support more protected bike lanes and trails. Children should be riding a bicycle to school and not be driven in a minivan. Be healthier and happier. Ride a bicycle regularly.

[CARLiCON]

you've reported previously about erythritol, (& now xylitol), could be linked to stroke & heart problems due to platelet effects, can you do a video on these? Have there a been studies on deaths directly attributable to ingestion of erythritol?
