  • Should you eat paleo or vegan?

  • Should you do crossfit or bodybuilding?

  • Is wine good or bad for your heart?

  • We are bombarded by varying perspectives on a variety of topics on a daily basis.

  • You need to sort out what's real and what's nonsense.

  • I'll show you how to do exactly that.

  • What's going on guys!

  • Dr. Jubbal from MedSchoolInsider.com.

  • That's right, it's Dr. Jubbal and no longer Dr. J. I came out with my real identity and

  • the truth about my struggles and my story in a recent video on the life of a surgeon

  • vlog channel.

  • Like is in the description below.

  • Many of our beliefs are plain wrong and not based in science or fact but rather in anecdotes,

  • word of mouth, or misinformation from seemingly trusted sources.

  • It's important to understand that many of our beliefs are socially constructed.

  • As humans, we are incredibly malleable in what we believe and how we perceive the world;

  • the influence of others holds tremendous weight.

  • Homo sapiens have evolved since our hunter gatherer times to follow the herd because

  • falling out of line could lead to being ostracized, which would ultimately mean end of the road

  • for one's reproductive fitness.

  • However, this desire to fit in and the resultant homogenization of our perspectives often does

  • more harm than good in our current age.

  • Throw in the power of clicks, money, and advertising with companies fighting for our attention,

  • and it's no surprise that its incredibly tough to determine fact from fiction.

  • In order to sift through all the noise and hyperbolic sensationalism and figure out the

  • truth, we must question our own beliefs and values to ensure that we have deliberately

  • chosen them and not simply blindly believed what we have been told.

  • Let's start with the pinnacle of progress and understanding: scientific research.

  • Many of us turn to the most recent journal articles to help guide our beliefs and ways

  • of living.

  • However, to get the most out of research requires a nuanced understanding of not only the study

  • design, but also subject matter, funding, and study limitations.

  • One of the best ways to witness the importance of these factors is by turning to nutrition

  • science, which still remains highly controversial.

  • One week it sounds like paleo is the best, the next week vegan, and the week after that

  • Mediterranean.

  • Here's an example; In 2014, Bazzano et al published a randomized trial comparing low-carb

  • to low-fat diets.

  • Many interpreted the findings as a landslide victory proving that a low carb diet is superior.

  • The low-carb diet, after all, showed an increase in HDL, which is your good cholesterol, and

  • greater weight loss.

  • This was a randomized trial, so it must good study, right?

  • Not so fast!

  • It is true that randomized prospective trials are better than retrospective trials, which

  • analyze data from the past and look for correlations.

  • However, by understanding the subject material and the study limitations, it becomes apparent

  • that like many nutritional studies, this one is far from perfect.

  • The study relied on self-reported dietary information which is prone to recall bias,

  • dietitians were not blinded, there were no cardiovascular disease endpoints, the low-fat

  • diet was really just a regular-fat diet, and fiber intake was less than half of the recommended

  • amount.

  • Additionally, HDL, your good cholesterol, functions to transport cholesterol from the

  • periphery to the liver.

  • Increasing the amount of fats and cholesterol you eat will require a greater amount of HDL.

  • If you have more garbage, you need more garbage trucks.

  • It does not necessarily make you healthier.

  • It's equally important to pay attention to who funds the study.

  • Data, but even more so common sense, indicates that industry funding is associated with pro-industry

  • conclusions.

  • The Vox recently came out with an excellent article explaining how the chocolate industry

  • has funded hundreds of studies that promote chocolate as a health food.

  • Is chocolate actually good for your health when unbiased studies are examined?

  • The take away is no, but cocoa-based products with little or no added sugar or fat do seem

  • beneficial.

  • For those of you who want a more scientific analysis, check out the systematic review

  • by Hooper et al that essentially said the same thing.

  • MANY OF YOUR BELIEFS HAVE NO SCIENTIFIC BACKING Now let's be real, none of us actually goes

  • to the primary literature for everything.

  • Nor should we.

  • Your beliefs don't ALL require scientific backing, but they do all require a healthy

  • dose of skepticism.

  • If I asked you how much water you should drink in a day, you may suggest 8 glasses.

  • The 8 glasses of water recommendation actually has minimal scientific basis, and can be traced

  • back to a 1921 paper where the author measured his own urine and sweat to determine that

  • he lost approximately 3% of his body weight in water per day, which is approximately 8

  • cups.

  • I'm not sure about you, but basing humanity's water intake recommendation off the results

  • of one man seems misled.

  • Your belief of whether or not there is a god is definitely not based on scientific fact.

  • People have varying opinions and it's critical to be aware that just because you do or do

  • not believe in one thing doesn't mean that another persons opinion isn't valid.

  • This is especially important when your beliefs aren't easily proven one way or another,

  • such as with regards to religion.

  • To sift through the misinformation, it is essential to practice critical thinking.

  • What is critical thinking?

  • It's essentially the skill of absorbing important information and using that to form

  • a decision or opinion of your own, rather than just reciting what you hear others say.

  • 1) Determine what's important Not all things require this level of analysis.

  • When deciding which movie to watch tonight, maybe you don't have to be 100% certain on

  • which movie would be best for your current mood and time allocation.

  • So first, determine what is important for you to understand on a deeper level.

  • To start, any behavior you are changing that significantly effects your health, life, or

  • well-being on should require a deeper understanding where you have practiced critical thinking.

  • As a doctor, I would argue that anything effecting your health, like deciding on which diet or

  • exercise to pursue, requires critical thinking and analysis.

  • 2) Pay attention to the right details In this day and age, we are exposed to an all time

  • high of information.

  • Information overload.

  • Determining which facts are relevant and which are irrelevant will serve you well.

  • First, question the source.

  • As we have already gone over, sources are not always reliable.

  • Thinking about who benefits from a statement can also help you shift your perspective and

  • view the topic in a more objective way.

  • 3) Challenge the argument The best way to challenge the argument is by asking the right

  • questions.

  • What is the counter-argument?

  • No argument is bullet proof, and it's your duty to question what you are told, to see

  • the other side and to understand both sides of the coin.

  • 4) Be wary of confirmation bias Rather than question our beliefs, its human nature that

  • we want to reinforce our currents views.

  • You may find yourself reading articles that align with your beliefs, but why not learn

  • about the opposing viewpoint?

  • Understanding both sides will not only guide you closer to the truth, but you also will

  • have a stronger backing and argument supporting your decision.

  • If you find yourself repulsed by a certain point of view in an argument, chances are

  • you are being closed minded and not objective.

  • Take a step back, acknowledge your bias, and reapproach the situation with curiosity rather

  • than your own agenda.
