Probably better to make a note of it. "annotation" is marginal or footnote entries in a book that go into detail on a highlighted subject. "Notation" is a noun that means the act of taking notes. "Making a note" is writing down a concept once to be reviewed later. "Notate" is not a word. A person doesn't "Notate" something. They "note" it or "note it down."

Wow, so many experts in the comments. All this guy is doing is relaying the outcomes of actual studies. Actual studies > your personal experience.

Dr. C is one of those people that could say "I'm going to talk about random shit for an hour." and I'd sit down and listen. Perfect voice and charisma for being a speaker.

LDL carries the cholesterol towards tissues, HDL carries it away. Therefore, LDL is 'bad', HDL is 'good'. LDL has more cholesterol, while HDL has more lipoproteins. Anyway, as I said in the comments the first video of your channel, I think this channel (especially this video) is a must for every medical student in the world.

This was probably my favorite episode yet. Do this again!

As much as I love the usual HT for making its points really solidly, many of us trust this channel for good info by now and this Q&A format covers a lot more ground in a more entertaining style. More of these or a Healthcare Triage podcast every so often would be really cool.

As a personal fitness trainer I always told my clients that they should skip the supplements until they reach a point where they are sleeping good every night, eating very healthy every day, and training intensely 5-6 days a week without compromise, and they feel they need to aid their body in coping with their intense training. Not as some kind of magic pill, so they can skip workouts, not put forth the effort, eat like unsupervised children, and still swell like Arnold.

the stretching thing is really surprising to me

***** Ah, but what exactly is being warmed up? Our internal body temperature doesn't change all that much, and when it does that's usually a bad thing (ie fever). Not to mention, what is the difference between stretching in advance and muscles being used during exercise? How does doing it in advance change anything? When you think about it, stretching doesn't really make that much sense.

Taking things with a grain of salt here; just because there is no (statistical) data that shows both to be beneficial, it doesn't mean it always isn't. I like to think of "warming up" and stretching as two separate things. Warming up can be anything like running or doing some exercises, which can exert the body just as much as whatever activity is performed afterwards. Stretching however, so long as you don't go overboard to stretch until you feel pain; WILL benefit you from straining muscles too hard later, especially before swimming. Don't want to get a leg cramps and drown in the ocean? Stretch. What happens to clothes of certain fabrics after they're washed and hung to dry? Unless you lightly stretch them out while damp/wet, over time they shrink, and shrink, to the point you feel like it's a size smaller. The same can apply to muscles. Long story short: everything in moderation.

***** I never get this wrong because I simply remember that LDL should be LOW, and HDL should be HIGH.

John, for the love of god, don't get botox. You don't need it, it's not you, and as a father you're basically telling your kids that physical appearance is important to social status and success. I will continue to watch your videos because they're good videos no matter how old and wrinkly you (perceive yourself to) get.

A friend smokes; however, he also exercises regularly and he believes that by continuing to be active; exercising the organs prone to carcinogens (heart, lungs, etc.) that he might be offsetting some of the damage caused by smoking? I have to admit; the guy works out hard; heavy cardio / Vo2-Max training /Road Cycling (20miles/day); and seems to be in good shape; even dives for abalone and can stay under water a lot longer than I can. But, this just seems like something a smoker tells himself to continue smoking - a professional opinion would be helpful to educate him (or myself?). Thanks - love the shows!!

Absolutely yes to the nutritional supplement answer- expensive pee. To the stretching- dynamic stretching before exercise prevents injury. Static stretching would not. Please be sure to specify the difference! Such a huge fan of this channel! :)

The world is in desperate need of this kind of evidence based approach to medicine and health. Thanks for your work!

On the stretching thing: it's important to note that he is talking about stretching before physical activity. In all honesty the best way to look at stretching is as another form of physical exertion. Obviously not an aerobic form. But stretching can be beneficial if done in a separate "work out" so that your muscles lengthen. Which is definitely good if your muscles are overly tight, pulling when you don't want them to.

Thank you. Thank you. Thank you. This show is wonderful. I know the information is out there, but a google search often returns a whole bunch of websites selling something, not the good research. And without the time (or priority, really) to read the studies and figure out which ones are more valid, it's so hard to get this information. I have completely changed many of my actions because of what y'all explained on this show (drinking milk, buying organic, talking about vaccines). And I thank you for doing this.

LDLs are bad - it helps me to think that the L is for Lethal HDLs are good - H stands for Harmless

Direct feedback! I really liked this format. Aaron is much more engaging/lovable when he's interacting with a person right next to him. Also, I continually appreciate your "the sky isn't falling" approach: helps us focus on the real things, e.g. regular exercise.

Very informative! I watched it straight through to the end. I'm so glad this channel exists because it's nearly impossible to get unbiased and accurate information from someone who truly knows what they're talking about. Keep doing what you do! :) it's great.

Oh this is a great segment! I hope you guys will do these every now and then!

This is a great video. Keep up the good work, Triage has quickly became one of my all time favorite video libraries.

This is probably one of my favorite HealthCare Triage videos yet. Dont' get me wrong, I love all these videos, but this one had a lot of good information packed into a single segment. Keep it going, we're listening.

I just realized how much more I enjoy watching Healthcare Triage videos without the constant jump cuts.

This was a real fun watch. Thank you, gentlemen. Now I want to meet Aaron real-live even more. He has a style of thinking that I really like.

This was actually a really informative and diverse video; I hope you get to do more of these Q&A videos. :)

I freaking love this channel. This was great, we need more of this type of video.

this has been the most entertaining interview, Q&A (or what ever you call this) on youtube. i've learned a lot and laughed a lot. you guys are awesome!

I only have one wish for this show. Whenever you mention a study/studies show, I kinda want them sourced, like links to those studies (hopefully somewhere on the screen) so I can look at them myself. I understand that this might logistically difficult. You are an expert I trust, I need that trust to be verified. Great show.

I like Aaron's casual style here better than the accusative style of most other videos. _Having said that_, I do find these video's very interesting and informing. Keep up the good work!

I absolutely love this channel! I'm always the one telling people to look up the studies. I hate hearin, "They say you should do X, or Y." My first question is, "who says that?" I always push people to look at the studies, the evidence, see what they say. And I love that this channel dives fully into that. If I could cuddle up with this channel, I would.

I really enjoyed this segment. I'm excited to see more of these videos.

But he's so handsome!

wow you just cleared up so many misconceptions for me. You should do more of these

Thanks very much for sharing the insight and professional recommendation. Small matter to clear up though: HDL stands for high density lipoprotein and REMOVES cholesterol from tissues, transporting them back to the liver for metabolic processes (HDL="Good"). LDL stand for low density lipoprotein and is an endogenous molecule with the function of depositing cholesterol INTO tissues arround the body ("LDL="bad"). Big caveat here though. As with most things, this is no black-and-white issue. Both LDL and HDL are critical for good health, so long as they're in their normal and healthy ranges. LDL simply gets a bad rap because in the modern archetypical picture of "poor health" (obesity, heart disease, etc.), LDL level tend to be much higher than normal, while HDL much lower than normal. Thus LDL being called bad, and what we typically want less of, while HDL being good and desired in greater amount.

I've been watching vlog brother for agess but I've only just discovered this gem of a channel. Fabulous.

LDL is bad and HDL is good! LDL is what causes hardening of the arteries, much more than HDL levels. Most medications and treatments today focus on lowering LDL levels.

So nutrition, exercise, stopping smoking if you smoke are the three things I got out of this talk. Whenever I hear or read of a new supplement or chemical that is touted to prevent disease, the first thing I do is to see if any scientific studies articles from professional journals are available online, at least abstracts. Then I research what foods these chemicals are in. Then I go to my *farmacy* and get foods that have them. Blueberries and grapes; cantaloupe; apples and dark green leafy vegetables; bell peppers and Brussels sprouts; rutabaga; and many other fruits and veggies I like. In fact, often I will go to the produce section and follow my cravings. I can't really go wrong with that. Then, for myself, I let myself eat eggs in any amount. Additionally, I let myself eat red meat at least once in a while. Not because I'm trying to cut it out-I love red meat and sometimes binge on a slow - cooker barbecued pork roast -but I have it often enough to calm my brain down. (I have bipolar.) Chicken and turkey don't do it, nor does fish. Beef, pork, mutton or lamb, ox tail, bison, and even emu do. And beef tongue. (I most often get pork.)

This was an awesome video! I love the health myth busting you're doing and I wish everyone I know would watch this

Really liked the Q&A! Would totally watch more of these!

As always, another great video from Healthcare Triage.

Would be great to see the study on stretching/warming up. Really hard to believe it's not working!

I'm so happy, you just removed the guilt I felt for never, ever stretching before strength training. Hurray!

Excellent episode! Thanks John and Aaron.

it was fun to see the discourse b/w John and Aaron... made me smile :D

As a nutrition student, I found the mix up between HDL and LDL disturbing, especially since the correction was in the description at the bottom. HDL is the so called "good" cholesterol and LDL the "bad" cholesterol. Although you are right, food consumption does not alter either (but exercise does!). Also, many people at many geographical locations would benefit from a vitamin D supplement in the winter.

Really great video! I hope you'll continue making them! :) I'd love to hear more about the vitamin supplements. (yeah, I know, a simple "NO!" is great, but, atleast here in germany, there are so much contradicting statements)

I really really loved this episode! Keep them coming!

Damn, totally missed out on the call for questions. Can't wait for the next one!

On the topic of stretching, I'd like to share my personal experience. Mind you, I'm one person, not a study group, but I've noticed the effects can be complex. Primarily I am a martial artist, and while stretching wont prevent me from twisting an ankle or breaking a bone, it does seem to have some effect on my ability to resist submission holds and other sorts of intentional attacks on my joints. It also seems to reduce my chance of pulling a muscle when I'm doing things like sprinting or swimming. Also, while stretching before a work out seems to reduce performance, and as such I have stopped doing this, stretching between work outs has vastly increased my range of motion, allowing me to gain more power, and a higher rate of acceleration, in fencing, sprinting, and in fighting. I think there is still a lot of good reason to stretch, even if the idea of it preventing lactic acid build up or common sports injuries is somewhat of a myth.

I love this style of video! do more of them please!

They likely buy from Peru, where it is semi-legal to farm coca plants (although I'm sure other countries have fields for medical/research purposes). So my guess is that Universities gain access through Pharmaceutical companies for research purposes.

I like the format. Thanks for doing this!

This video looked like it was a lot of fun to make. I think that is why I enjoyed it so much :)

First, just ran across this channel, and I like it a lot. Second, I have one specific point of difference from what I thought you said in the video. Specifically, I think there is a much stronger link - than admitted by conventional(?) advice - between protein intake and the body's response to exercise. Many years ago, in high school. I was in athletics (cross country and track), and did fairly well. At the start of high school, I was a 90 lb kid (with no thought I could end up in athletics). Once in athletics, I spent near an hour in the weight room every weekday, trying to build upper body strength, with very limited result. By the end of high school I was a 120 lb kid. My diet consisted mainly of massive carbohydrates. (For a nutrition class I estimated my intake was 11,000 calories per day. Also, our cross-country coach scheduled some pretty intense workouts - and ran with us. Hard to complain about the workouts when the coach runs with you - and ahead. Also our cross country team did very well.) I do recall looking up the then-current dietary recommendations for protein intake (in the early 1970's). My (very) hazy recall is that 10-20g (or less?) was all that was then thought that the body could use. Rather a lot of effort, and very little result. A several years back, I started going to the gym regularly. Of course, for the first few months my workouts were fairly pathetic, but improved somewhat - if not a lot. Then I thought to look up advice on protein intake. The science in this area is more than woolly, but the advice offered suggested more protein might be effective. Well, protein is cheap, so ... why not? I boosted my protein intake above 100g/day. The frequency of visiting the gym, and time spent in the gym stayed about the same. Oh. My. God. My upper body strength increased rapidly. My subjective level of effort was the same. My daily workouts at the gym are under 10 minutes. My upper body strength - geez, I do not really know - quadrupled? More? Maybe a lot more. (If I knew this was going to happen, I would have made more of a record.) I exceeded my goals years ago. (Got harder to find clothes that fit my upper body.) I backed off and was content to maintain my current level. But ... I am still(!) gaining. To be clear, this is only from adding more protein to my diet - nothing else. My blood chemistry numbers also changed, very much for the better. I am currently a 59 year old male, and all but one of my immediate ancestors died of heart problems near my age, or earlier. Also ... and this is more speculative ... the muscular soreness after hard exercise seems much reduced in duration, and effect. No assertions here, just a question.

IS this really the first Questions video? I swear there was another. also YAY a questions video.

You guys rock! Keep the light of evidence based medicine shining! :D

Fantastic! Thanks so much for these you guys.

I learned from my doctor that HDL is good and you want it to be high (they both start with "H"). LDL is bad and you want it to be low (both start with "L").

That was a very enjoyable video, as well as informative (although as a skeptic, none of this really surprises me). Please make more. :)

Oh god, the milk bit at the end was hilarious.

I love this channel, keep up the good work.

I've heard the thing about stretching before, but I'm always hesitant to bring it up because I balk at the idea of having to defend that against my entire cross country team and coach all without having an internet connection at practice.

Great Q&A session! Definitely keep it up!

Is that what was implied in the conversation about John's guns? Thanks in advance!

In this context: an expert speaking in an informational video, it is especially important that casual phrasing not support bad thinking and unsupported but common beliefs. I think Dr. Carroll agrees that you can't tell a person's diet by looking at them, so that is why I suggested he not say it, even conversationally. Because that belief is actually held by many people and can be quite hurtful when expressed.

vlogerhood Ah, point well taken.

I appreciate his comments at 13:00. I was always curious about vitamins. He's saying supplements are of no help, but vitamins can be if you're deficient. If you have a balanced diet (which most have) multi-vitamins won't help you as you'll pass them through. However, if you're deficient and have an imbalanced diet, a multi-vitamin will help to fill in the gap. Sounds like there's a ceiling whereby supplements won't help further.

I'm in love with this channel

My understanding of the stretching thing is this: When you stretch, it does more to separate the muscle fibers. Kinda like "ripping" though muscles don't actually "rip". But in either case, when you go to exercise, if 10% of your muscle is "ripped", then the force is focused on the remaining 90% and thus you perform worse, gain less, and are at more of a risk for injury. The main benefit I can think of is avoiding tendon damage due to lack of flexibility. But in that case, you can do something like yoga at any time to get the same benefit.

This was cool, enjoyed fun interview format this week. Thank you. Also: ALL HAIL OUR MILK-INDUSTRIAL COMPLEX OVERLORDS. >_

Correction, at about 9:30. LDL is the bad cholesterol. HDL is good cholesterol. Low density proteins are big and chunky and cause blockages, High Density proteins are all smushed up and kinda just do their own thing regardless of your clotting factors. VLDL is the worst though, Very Low Density Lipoprotein.

I would love to see an episode putting the potential side effects of vaccination in perspective. I have a medically fragile child and have spent a fair amount of time in pediatric ICUs, where babies with whooping cough were dying so I am an even bigger advocate of immunization than I was before. Fear of side effects is one of the major oppositions I have had thrown up. Also the skewed data "showing" that the fatality rates from these illnesses were reducing before immunisation was introduced - I would like to be able to show that this was because of improved medical care, NOT reduced rate of infection.

In regards to the satisfaction question, I find that very true. My sister was going through a stressful time in her life but was not suffering from any mental illness like anxiety, but her doctor still gave her anxiety medication so she left there happy.

I glad you made the distinction between multivitamins and supplements. Some people act like it's crazy to take multivitamins as well, whereas it seems kind of obvious that if your body is a little low on something it can get it from the multivitamin whereas taking huge amounts of individual vitamins is just going to cause you to pee them out.

That was FANTASTIC!

Clarification on a couple things please! First, on the topic of supplements, does the same hold true for prenatal vitamins? Second, I was taught in A&P that LDL is the bad, and to remember this by thinking of the L as standing for lousy. Was I taught wrong? *edited later, I read the "about" section and saw the mix up. Forget I asked! =-) Love the videos, think I like the Q&A format even better. Definitely love how much data you have to back you up. Keep it up!

I'm kind of embarrassed that you answered a joke question from me haha. Very good video guys!

As far as stretching in the gym is concerned, I suggest light-weight warm ups, and not stretching. You never want to go into a lift cold, but to stretch is simply to stress the muscle without getting blood to it. Where as a warm up (for example, squatting the bar alone before adding weight) targets the proper muscles and gets blood into them.

I can not go to nearly any place in KZread with out goddamn John green showing up

Thank you for this! This cleared up a lot of misconceptions that I had.

Definitely do more. Free healthcare advice is nice.
