Netflix Hack Your Well being Overview

When Hack Your Well being: The Secrets and techniques of the Intestine got here out, I knew I needed to overview it. As a lot as I can’t stand Netflix diet documentaries, I do know everybody needs to learn a synopsis and my ideas about these often-sensationalized films.

In contrast to a few of the Netflix documentaries, I discovered this one was comparatively nicely finished and I agree with the take-away messages they shared.

However it isn’t with out some criticism. Let’s dive in.

Intestine well being has been a well-liked space of analysis for the previous couple of years, and we’re simply beginning to scratch the floor of what the well being of our intestine means to our total well being. Persistent well being situations akin to sort II diabetes, weight problems, irritable bowel syndrome, arthritis, sleep issues, melancholy and anxiousness have all been related with poor intestine well being, however we aren’t certain of the precise mechanisms by which they’re linked. 

As Tim Spector, a genetic epidemiologist from King’s School in London says within the movie, “That is new science, the tip of the iceberg. There’s one other 97% extra to find.”

That is true: we have now restricted human analysis, particularly on people. Preserve that in thoughts.

The Netflix Hack Your Well being Stars:

Maya is a pastry chef with orthorexia who has a restricted eating regimen. She’s even afraid to eat her personal meals. She eats principally greens after which dietary supplements her eating regimen with “potions and powders,” and finds the wellness business very complicated. I feel lots of people can relate to that.

Daniell is a doctoral pupil with persistent intestine ache. She started to endure after consuming unhealthily throughout her undergraduate years. She has taken many rounds of antibiotics to assist her signs, however with no impact. She now associates consuming with anxiousness, ache, and discomfort and might solely eat 10-15 meals.

Kimmie is a single mother struggling to reduce weight. She wonders if her intestine well being is why she has not been as profitable as different individuals in shedding weight. 

Kobi is a retired aggressive eater who has eaten over 10,000 hotdogs. He can not really feel any starvation or fullness cues, and might go days with out consuming. He’s nervous that his profession has broken his intestine past restore. 

These individuals all did at-home gut-testing by which their poop was analyzed to see what sort of micro organism it contained. They used a intestine well being take a look at referred to as Floré that’s out there on-line for $299USD. As per the web site, the makers of this product state: 

“Our intestine well being take a look at can detect over 23,000 microbes in your intestine, together with micro organism, fungus, yeast, parasites, and viruses. With using complete genome sequencing expertise, we are able to detect these all the way down to the pressure stage and the relative abundance of every microbe. Use your report to find out which meals and dietary supplements are greatest for you or improve to our Precision Probiotics in your customized intestine well being answer.”

Proper. There’s the gross sales pitch, full with an upsell. Pink flag.

Tim Spector is among the specialists reviewing the outcomes with the individuals within the movie and seems to be quite supportive of those assessments (in all probability as a result of he sells them too – see my overview of Zoe right here). His perception is that these assessments might help us establish particular meals we should always and shouldn’t eat based mostly on our intestine microbiome. 

Dr. Guilia Enders, writer of the e book Intestine: The Inside Story of Our Physique’s Most Underrated Organ, says that these assessments are not more than a enjoyable experiment. She finds them pointless, and says which you can don’t want assessments to deal with your intestine higher. Enhancing our eating regimen (we’ll discuss that in a minute) is what most individuals really need, not microbiome testing.  

I 100% agree along with her, and for this reason: at this level, we don’t know what the optimum gut-microbiome appears like. Realizing that, what are the outcomes of those assessments being in comparison with? These assessments additionally solely analyze your intestine micro organism at a single cut-off date, and we all know that our intestine can change rapidly based mostly on what we eat, stress, antibiotics, and the atmosphere. 

A microbiome take a look at that, for instance, tells me to not eat apples, sausages, and cake, is mainly pulling this out of skinny air. Do we all know that the Customary American Weight-reduction plan seems to have a detrimental influence on our intestine microbiome? Sure. Does this imply I ought to by no means eat sausages or cake? After all not.

And upselling dietary supplements for a ‘customized intestine well being answer’? Have they got a billion completely different probiotics to go well with the microbiome of each single one that takes the take a look at?

That’s 100% advertising spin. Don’t purchase into it. Most individuals don’t even want probiotics (I wrote about that right here).

I want we as a society may deal with the BASICS – that’s, enhancing the standard of our diets as an entire, eliminating suggestions that drill diets all the way down to single meals, and simply consuming sufficient crops, which solely round 1 out of 10 of us truly do. That’s what can truly assist our microbiome.

Why do we have to hack all the pieces and take a look at ourselves for info that’s mainly ineffective?

I requested Leigh Merotto RD, a intestine well being dietitian in Toronto, for her ideas on these assessments. She had this to say:

“Specialists agree {that a} wholesome intestine microbiome ought to have a range of microbes and species, however what these numbers appear to be, is just not but outlined. The truth that these assessments declare to diagnose “wholesome” quantities of micro organism, is solely based mostly on their very own parameters which is, in my view, unethical. Additional, viewing the corporate’s web site, they promote dietary supplements to deal with completely different “issues” their take a look at can diagnose, so it’s all the time a pink flag for me to be cautious when an organization seeks to let you know that you’ve an issue, and promote you an answer to repair it.”

Again to Kimmi. When the specialists checked out her take a look at outcomes, they discovered that she had a much less various microbiome, and no Prevotella micro organism. This seems to be an identical discovering in others who’ve a tough time shedding weight. 

The specialists inspired Kimmi to deal with sustainable eating regimen modifications and to extend vegetables and fruit to assist her enhance her intestine well being. This highlights that we are able to’t truly do a lot with the outcomes of those stool assessments. Merotto provides, “whereas it was clear within the documentary that these assessments can present sure ranges of useful micro organism being “low”, they didn’t have any scientific suggestions to deal with these ranges, aside from to eat a extra plant-diverse eating regimen. We don’t want them to shell out 100’s of {dollars} on a stool take a look at to inform them that they want to try this.”


We additionally don’t know at this level how a lot of an influence a particular sort of micro organism can have on the power to reduce weight. Weight problems is a multifactorial persistent sickness and whereas intestine well being might play a task, there are such a lot of different components to contemplate. 

Hack Your Well being: Analysis.

The movie attracts on analysis by Dr. Jeffrey Gordon, a researcher from the Washington College College of Drugs in St. Louis. In a 2008 examine, he transplanted intestine micro organism from similar twins the place one was overweight and the opposite was lean, into mice. The mice that acquired the micro organism from the overweight twin gained extra weight on the identical meals in comparison with the mice that acquired micro organism from the lean twin. 

Whereas that is undoubtedly an fascinating outcome, it doesn’t inform us a lot about free-living people in the actual world. 

Additionally they drew on comparable analysis on psychological well being which discovered that when mice got micro organism from an individual with melancholy, the mice began to indicate comparable signs and there have been modifications in serotonin ranges within the intestine and mind.  I’m not doubting the gut-brain connection and we all know that the majority of our serotonin is produced within the intestine, however once more, we are able to’t make any particular conclusions on people from this analysis. 

fiber and gut healthfiber and gut health

Most significantly, what suggestions can we give to people, based mostly on these research? Melancholy and the intestine is an interesting matter, but it surely’s necessary to not ignore reverse causation. Does a poor eating regimen give individuals melancholy attributable to altering their intestine micro organism, or does their melancholy result in a poor eating regimen and adjusted intestine micro organism? It’s arduous to say, and it might not be the identical reply for everybody.

Kobi’s stool take a look at discovered that he had fairly good intestine micro organism which they thought might be associated to his conventional Japanese eating regimen. He additionally did a mind scan and based mostly on the outcomes, they thought that a few of his points had been associated to the truth that his mind is used to him being a aggressive eater.

Quite than giving him something radical to do, Dr. Enders suggests he attempt to hearken to his physique and honor all his senses when consuming. Whereas Kobi’s case is excessive, making an attempt to get extra in tune with starvation and satiety alerts is one thing many individuals can profit from. I agree with Dr. Enders right here, though for individuals who grew up being informed to scrub their plate, or who’re persistent dieters, making an attempt to reconnect along with your physique’s cues is a course of. It could appear easy, but it surely’s not straightforward, and it takes time.

Fecal Transplants

Let’s get into fecal microbial transplants, or FMTs, which is the place another person’s poop is put into an contaminated affected person. This remedy is authorised by the FDA to be used in just one sickness: C. Difficile. This situation is when micro organism inflames the colon and causes horrible diarrhea to the purpose of being doubtlessly deadly. Analysis is ongoing to see if FMTs might help in different sicknesses, however once more, there are nonetheless loads of unknowns.

Regardless that it has not been authorised, we be taught that Daniell has been making an attempt FMTs and acquired feces from each her brother and boyfriend. We see her transferring poop from her fridge into take a look at tubes to be became poop capsules. When she obtained feces from her brother, she had some enhancements in her signs, however she discovered that she additionally obtained his pimples issues. She then switched to her boyfriend’s, and located the pimples went away. Nonetheless, her boyfriend has psychological well being points, and as soon as she began to make use of him as a donor, her melancholy was exacerbated. 

This seems like a dumpster fireplace, to be trustworthy. Whereas there may be some preliminary analysis that implies that melancholy and anxiousness might outcome from (or be alleviated by) FMT, this anecdote served as much as us by the movie is simply that…an anecdote.

Once you get the nice micro organism from somebody in an FMT, you additionally get the dangerous. There are additionally big dangers to randomly inserting another person’s poop into your physique, so please: don’t do that at residence. 

When Maya’s intestine well being take a look at was reviewed, they discovered that she had a fairly “wholesome” microbiome which is probably going attributable to all of the greens she eats. They reminded her that whereas consuming a kale salad day by day is nice, it’s not sufficient and inspired extra range along with her meals. We then see her specializing in including potato chips again into her eating regimen. 

For somebody affected by orthorexia, including potato chips into their eating regimen is a big step. It might have been nice if that they had additionally given her some particular examples of different plant-based meals to devour that will contribute to bacterial range, akin to complete grains, fruits, legumes, nuts, and seeds, however maybe they didn’t wish to worsen the state of affairs. I feel there’s much more to the story than we’re seeing right here.

It isn’t unusual for individuals with persistent intestine points and histories of consuming issues to have concern and anxiousness round meals. That is the place working instantly with a dietitian will be useful. A dietitian might help you slowly add meals again to your eating regimen and monitor signs.

Netflix Hack Your Well being Overview: In Quick.

In comparison with different Netflix diet documentaries Hack Your Well being was pretty nicely finished. The specialists had been clear that we have now much more to be taught in regards to the gut-microbiome, which is an effective overarching message. So is the advice to eat a eating regimen wealthy in complete, plant-based meals and goal for 20-30 various kinds of crops every week to assist promote a wholesome gut-microbiome. 

Together with fermented meals can also be useful as nicely.

Nothing about this film is a ‘hack.’ Entire meals, extra crops, and sustainable modifications have been promoted by dietitians for years. Stable recommendation.
