Replay of Dr. Greger's live Q&A on Thursday, May 23, 2024.
Questions asked during live Q&A:
0:00 Introduction
0:42 Can you give me tips on how to optimize health, strength, and fitness?
1:35 Can you rinse salt out of canned vegetables? Or can you add potassium salt to counter the sodium?
2:38 Is berberine poisonous? Should I eat barberries?
3:33 What time should you stop eating before bed?
4:00 Can eating too many nuts, seeds, and avocados raise my LDL cholesterol?
4:55 Are you planning an update on the March Study showing a 91% increase in cardiac mortality associated with intermittent fasting?
5:42 Do the advantages of algae outweigh the disadvantages, such as contamination with heavy metals? Which algae are the healthiest?
7:32 Red vs green rooibos tea. Which is healthier?
7:45 A study from Charité Berlin showed that regular blood donation could lower blood pressure. Are there any other health-releated advantages from blood donation?
9:02 Are prunes or dates high in polyphenol oxidase (PPO) like bananas? Any other fruits or just bananas to worry about?
10:05 Does B12 definciency cause intense sugar and salt cravings?
10:32 I had intense sugar and salt cravings then my doctor put me on statins and they went away. Now that I'm off statins, the cravings are back. What explains that?
11:00 Have you looked at research on therapeutic use of psychedelics?
12:05 My LDL and total cholesterol remain high in spite of being WFPB for 8+ years. I have a family history of cardiac disease. What else can I do?
14:50 Are 90 grams of nuts and seeds (~3.20 oz) per day too much? Where is the tipping point for nuts and seeds?
15:14 I have just stopped using all non caloric sweeteners. Are there any studies that show how long it might take my body to start responding appropriately to carbohydrates?
15:55 Does listening to music while exercising decrease level of testosterone in men and women?
16:48 I have been making a drink with matcha, flaxseeds, curcuma, amla, ginger, and soy milk. Is this good?
17:25 I love foods rich in spermidine for longevity but recall hearing that spermidine and spermine may be culprits for cellulite. Must we accept cellulite to gain spermidine's longevity benefits?
19:10 Can you comment on nitric oxide? Do you agree that the way to maximize intake is to eat leafy greens 6x per day?
20:15 Can you talk about microscopic colitis and how to stay on a plant-based diet if you've been diagnosed?
20:51 An article in a health magazine that says that grains, legumes, potatoes, nuts and seeds cause inflammation of the gut and permeability. Is it true that these foods cause inflammation of the gut?
21:32 Many doctors recommend some animal protein in the diet. Part of their reasoning is that the fiber in plant foods interferes with the digestion or absorption of plant-based protein. Are they right?
22:29 I've been making the delicious Okinawan Smoothie from How Not to Age on repeat! Are there any updates on the How Not to Age Cookbook or recipe sneak peeks?
23:24 Do used coffee grounds have any health benefits for humans?
24:26 What is the maximum amount of caffeine that a slow caffeine metabolizer can consume without any negative health effects? Is zero optimal?
24:50 Any negative side effects to eating a lot of berries?
25:21 Could you comment on the proper percentage of the macros for someone with non-alcoholic fatty liver syndome?
26:28 Should Vitamin D3 be mixed with saliva (i.e. chewed)?
27:05 I have prostate cancer. Are canned mackerel and fish okay or remove them? Protein powders like whey and soy? Should I avoid choline in B-complex vitamins and protein powders?
27:58 Daikon vs red radish-which is better at making sulforaphane? How much radish to eat per meal?
29:27 Next webinar announcement: June 14th on anti-aging drugs

can you a review of the study more protein better aging. is it really the more protein or is somethign else at play. see study which is mention in this video kzbin.info/www/bejne/m4HbdJiBjdh3apY

[@janpetersen4397]

Miss the treadmill!!

[@kin.9133]

Don't worry about making people seasick, you do you boo, they can listen to the audio only if they don't like it

[@Joseph1NJ]

I did an n=1 experiment with avacado, ate it every day and it did not negatively affect my cholesterol.

[@martinabattistich387]

Maybe it depends how high it was your cholesterol. Dr G. Said it lowers small ldl cholesterol if I remember correctly

[@howardlefsky4756]

Why would it?

[@Joseph1NJ]

@@howardlefsky4756 It's a lot of fat. And yes, I know what type.

[@howardlefsky4756]

Unsaturated fat does not raise and can even lower LDL. Beginning, middle, and end of story.

[@Joseph1NJ]

@@howardlefsky4756 Unsaturated fats do not lower cholesterol. It's only when saturated fats are replaced with unsaturated fats cholesterol falls.

Thank you for all the time you give to share your knowledge-making the world a healthier place! ❤️

[@AndrewPawley11]

I love this channel!

[@TheDooskinCO]

Thank you for your time!

[@amyb9556]

Thank you for all you do.

Obsessed with this guy

[@Alexander-ok7fm]

Thank you for your answers! 😊

[@PeterBilland]

We need to get a stationary Bike for the good doctor.

[@NanaPiper]

Thank you!

I knew a pt therapist that was selling blue green algea as a multilevel suppliment. My answer to his solicitation was " you mean the stuff that kills your dog at the lake? I will pass"

[@oskariKN25]

...cacao? Coffee? Allium plants like onion and garlic too?? You eat none of those because your dog dies if he eats them? You base what you eat based on your dog...? Also another bit of common knowledge that was lost to you in the developmental years of your life, there are strains and multiple species of plants belonging to the same family that differ in their properties, there are blue algae that are not toxic, tomatoes, bell peppers and eggplants are nightshades, a plant family known for its certain wild species known to be poisonous, this also includes cannabis. Please in the future determine what you eat based on human physiology. Comments always have such oddballs in them...

[@janetg1691]

Thank you. I ordered your How not to age book (Dementia interests me).

[@carolfosterhall4118]

Dr. Greger, I would love to find out more about healing from Microscopic Colitis as I and 2 siblings all suffer from it. It seems as though most beans and lentils trigger flares for us as do onion, cabbage & broccoli 😥 . (Weirdly chickpeas and navy beans seem safe as do red lentils, curious about the science behind that; will probably never know!)

[@dominicmutzhas6002]

Should WE Take berberine in days that er exercise then? Or days where WE want to perform physically?

[@leftyfourguns]

So if there are indeed health advantages to blood donation, does that mean there was actually some merit to medieval blood-letting?

[@oskariKN25]

A time when a cough could kill you and the most crucial time to not lose blood and thus white blood cells... Can't say the benefits outweighed the problems. Im quite sure medieval people had more health problems than just slightly high ferritin levels.

[@denisesmith8332]

What are your thoughts on K2?

[@contact2001]

Search for it, Dr G did a video slightly over a year ago if I remember correctly

[@jakobw135]

What about taking a VEGAN PROTEIN SUPPLEMENT?

[@lucam2942]

Anyone know if a French press Is just as good as using paper filters?

[@lawrence4999]

Dr. Greger said they are not as effective (in this video and I think the previous or 2nd previous live Q&A). the reason is that you are more likely to drink some fine particles of the ground coffee

[@jamescharles4904]

Drinking filtered coffee is healthier than drinking French press coffee ☕️. So, I've read. Google it!

[@marybitter9119]

If low dose calcium supplements are taken three times a day, is that safe?

[@weirdunclebob]

As you don't show graphs or anything else that people may want to look at, I have potential solutions for the seasick people so you can still walk on your treadmill while answering these questions: 1. Don't watch it! Just listen to it. 2. If you need to read the questions, scroll up until only the questions are showing. Can't be keeping the good doctor from his exercise! 😁

Si no lo podemos ver en Españaol no me vale por favor traducir a Español gracias gracias

[@martinabattistich387]

My Gynecologist told me Today that soy thickens endometrium so she and her other colleagues (in Rome, Italy) suggest now to stay away from soy. Any comments? (I was late for the Q&A)

[@rn5697]

Is low carb bread 12g carbs per 100g good in keto and diabetics

[@SecretMountainTroll]

Don't eat chlorella?

[@proudchristian77]

If u stay skinny everything works , if u blow it up , gosh baby , help us were lost , no wounder, y u stay skinny! 🎶 🎶🎶🎶🚴‍♀️

Avacado and bananas turn brown, don't tell Dr Goldner not to eat them.
