I’ve finally found my calling! 39 years and I am just learning about this field... Welp, better late than never ever... 🧠🥰 (Future me re-reading this: Yea.. it’s hard. Really hard. Harder than you thought! So what? Work even harder! You got this! Remember your reasons and focus on the journey. One day at a time. 💪🏾💗🙏🏾

[@Koruscinematics]

Nice im studying it right now in middle school lol.

[@ruairidh5796]

How goes the journey?

[@booberfraggle]

How is it going?

[@fortcastlevgn2368]

she lies a lot about so many things in nutrition (im obsessed by wfpb doctors) SHE LIES A LOT!!!!!!!!!!!!!!!!! and on EXTREMELY SERIOUS HEALTH ISSUES

[@mystic3656]

Same!! 37!

[@TheOn3LeftBehind]

This was a very helpful video! I’m familiar with research indications in psychology and neuroscience, but I think learning about the point of epidemiology is extremely useful for how the research we do is important from a bigger picture, too, as scientists in my field can get lost in the small details.

[@artinsafaie]

People doing this for a job, me having to study this as a 5th grader for Science Olympiad..

[@klutz3955]

Lol atleast you had that type of activities. I never had a thing like that during my entire school career. Matter of fact I'm watching this for my MD

[@eddy3414]

Haha same

[@Dovelunalove]

Um...I’m watching this for college as a health science major 😩 they teach kids at higher level these days.

[@18_rabbit]

@@Dovelunalove so u should work that much smarter or harder.

[@Dovelunalove]

@@18_rabbit yes definitely having to work harder to meet the standards but once you’ve applied yourself it’s not that hard..still I’m like damn shouldn’t I already know this stuff, why didn’t they teach us this in highschool/ middle school 😩😭

[@myreyabeltran4401]

People keep telling me to give up red meat because it is associated with cancer, so I am going to share this video with them next time! I love the way that it was reframed. It gives a better understanding on why it may be true, but not necessarily urgent.

[@fortcastlevgn2368]

she lies a lot,, YOUR BIASED BY YOUR OWN ADDICTION TO SATURATED FATS,, animal fats are THE MOST ADDICTIVE crap for us douglisle psychologist neal barnard many wfpb doctors not gona name them all people here are too fkin stupid in this area to start vegsource youtube,, plantchompers,, oh list too long go educate yourself gniosophobia

Realy helpful

[@idahosaconfidence7179]

I never thought that online treatment was real Until a friend directed me to a doctor called Dr OFURE who directed me on how i will be cured from HPV and i did as i was directed and to God be the glory i went for a check up and it was negative i want to use this opportunity to thank doctor OFURE and you can contact her on EMAIL [e-mail] or her whatsapp number [phone] she can cure different type of sickness He cure listed diseases CANCER HEPATITIS A AND B DIABETIC. HERPES HIV/AIDS...

[@gigglysamentz2021]

3:00 I don't get that point. If you include only people who eat a lot of ice cream and live in hot countries, you don't have the data points to say that people who eat less ice cream don't get burnt as much.

[@gigglysamentz2021]

So the association won't seem strong...

[@chandrawatimaravi9176]

Hidhi me epidemiology principal ,objects, control, prevent, treatment method

[@fortcastlevgn2368]

nicely pointed out (and also lupus is directly linked to dairy,, creates massive inflamation making you alergic to the sun and almost all skin issues are STRONGLY LINKED TO DAIRY consumption (like psoriasis obvious one all acne (since hormones fat and sugar in dairy no traces of fiber no help for stabilizing and evacuating

[@fortcastlevgn2368]

huge majority of people are biased on the side of dairy products because it is an insanely addictive substance for so many people (neal barnard cheese trap,, the pleasure trap by dough lisle,, kristy funk on cancers,, same for collincampbells (all the sources you need enjoy and they will source even more sources as you listen to them,, they crazy smarter then me im just a vegan wfpb activist

[@gigglysamentz2021]

A p-value of 0.05 is quite high in my opinion o_O

[@dh091220]

no one cares about your opinion

[@TheOn3LeftBehind]

It’s still significant at that level and smaller, though. I can see what you’re saying when p = .05, but that’s definitely the cut off. It may not be strongly significant, but it’s still significant. For some reason other scientists even consider “marginally significant” results as trends, which I can understand if you think you’re getting close and want to push for future direction, but don’t call it marginally significant!

[@YouDontForgetThis]

Really useful video thank you!

[@dennisbenjaminahndorf]

Minute 5:30; a 20 times increase is an increase of 1900%, isn't it!?

[@gigglysamentz2021]

No I think they're right. "Being 20 times as likely to get cancer" would be a 1900% increase.

[@riskbites]

Yep - technically the increase is 1900% - good catch. Yet using the term "increase" in a looser way to represent a comparison between before and after (which gives you 2000%) tends to be easier to comprehend in a context like this, despite not being technically accurate. A tradeoff between pedantic accuracy and understandability :)

[@akilletaylor6716]

how did you calculate it.

[@fortcastlevgn2368]

dairy doesnt cause it directly but indirectly it can severely make us vulnerable to it (skin inflamation (everyone have a little lupus but at a different level (everyone have a little cancer,, everyone have heartdeseases plaque since 10 years,, michael gregore,,, and cancer overall (everyone have a little sickness of everything,, inflamation and bones getting weaker,, everyone (maybe vegans wfpb since birth and semi athlete that are wfpb are in the least worse) but not much studies on those

[@blackholeil7900]

hi ms Delatorre

[@seikou9682]

this is a wake up call for me. i smoke cigarettes and drink coffee.

[@benjaminwilcox8748]

thank you

[@ongoingacademicmedicallear6202]

Is ☕ coffee the predisposing factor to get cancer risk?and what is the the difference between coffee and other CNS stimulants? Could l have your email ,please?

[@syedahmedyoutube]

Here is a research based post you can look into instagram.com/p/CDRoRXtngWe/?

[@bhagyajyothiarun7545]

Good one but too fast

[@Magani79]

harmful studies on animals is also "highly unethical"

[@theclavers]

Agree 100%

[@tacticalone8764]

I am pro animal rights, but I am team human first. Would you rather we saved lives of children before mice? Animal testing is unpleasant but necessary.

[@Magani79]

​@@tacticalone8764 I agree, some things should be tested on animals. The only problem is much of the animal testing that's being done is unnecessary, or not even providing good science that we can rely upon (because of the differences between humans and the animals)

[@daffyrose]

My admittedly rough research suggests that 14% of the US population smoke whereas 64% drink coffee. So where does the people who drink coffee tend to smoke conclusion come from?

[@katherineli5440]

i havnt done any research myself but it does not have to be a 1:1 correlation (100% of coffee drinkers do not need to be smokers). If people who do not drink coffee make up a smaller percentage of smokers than people who do drink coffee, then the correlation is valid. It's just that making causational conclusions from that information would be interesting lol.

[@joshuagordon5643]

you are very biased

[@hydroecologicalservicesisp8433]

1.the exemplify epidemiology is disgusting

[@nathanvermaerke2168]

Brief summary: How to test whether something is harmful? - In vivo studies: research in animals • Not the same effects in humans! - In vitro studies: research in cells • Cell out of the body behave differently! - Studies on humans = best approach • Warning: can be unethical! Therefore, we can: o Observe world, where are people exposed to? = observational studies: exposure  health. o But exposure  health, doesn’t mean the 2 events are related. (ice-cream consumption and drownings, these are correlated, but not causative) • Reason we might see an association: o Cause o Chance o Bias: can occur because of errors (in design). o Confounder: some other factor(s) confuses our interpretation. E.g., People who drink a lot of coffee are more likely to develop heart disease, tempting to conclude that coffee causes heart disease, but people that drink coffee tend to smoke. In this case smoking is a confounder (associated with both coffee and heart disease), which make can make it seen coffee causes the condition. • What information matters? o Use statistics, the p-value (≤ 0.05), but doesn’t tell much about importance, rather tells if it is true or not. E.g., both smoking and red meat causes increase in cancer risk, but smoking causes a 20-time increase and red meat only a 0.2-time increase. o This is why looking at the p-value is not enough and also considering effect size is needed to know the importance.
