[@iandiederen9349]

all of these fat facts made my brain so stimulated that i probably lost about 0.5 extra calories today. thanks sci-show for keeping us healthy!

[@luxtenax9175]

Oh, you guys using the snatoms would be really nice for your future videos. It makes me want some the more I see how useful they can be, even though at first I was doubtful about buying them.

[@pratofundo]

I don't agree that trans fat and hydrogenated fat are the same thing. The hydrogenation process can produce trans fat if incomplete, but the main goal is transform polyunsaturated fatty acids in saturated fats as you know. And trans fat occurs naturally in products derivative from ruminants. I guess it was an (over) simplification between the process and the chemical nomenclature, but can cause confusion. p.s.: I don't think Derek will agree with the bond energy explanation… hehehe I watched the "Logic Problems, Energy, and Lollipop" episode! :)

[@fran6b]

+PratoFundo I'm not qualified to respond to you adequately, but as you said, I've been taught that the bad fat was the Partly Hydrogenated one and not the Hydrogenated one. Though, I can't explain more.

[@romayi7983]

+francis bélanger the partial hydrogenation produces trans fat. Artificial trans fat is unnatural compared to its ruminant brother and bc it is a fairly new addition to the human diet, the body doesn't really know how to break it down (my hypothesis based on readings and college classes dealing with food & nutrition/food & health/ food science). The chemical structure of TF is slightly diff from UFA. While UFA has a double bond on the cis side, TF's double bond is on the trans side, creating a different looking "kink". Because TF is fully hydrogenated, it remains stable, which is good for food developers long shelf life, stability, and temperature withstandability but not so good on your arteries. Just to show how much more detrimental trans fat is to your health, there was a health study from the Nurses Health study from 1980-1994, that showed for a 5% increase in energy consumed in the form of Saturated fat, there was a 17% increase of the risk of heart disease. For a 2% increase in trans fat, there was a 93% increase in risk. I'm sorry if I didn't really answer your question, but I just wanted to share what I learned.

[@fran6b]

+Roma Yi I appreciate your answer, and the fact you use the word hypothesis instead of theory ! ;)

[@FusionDeveloper]

+PratoFundo THANK YOU! Finally someone else that understands that the term "transfat" does more harm than good. Classifying all types of trans fats as being 100% identical and equal, is a VERY dumb thing to do. It promotes ignorance and people fighting for causes they misunderstand. I would rather eat natural bacon fat, than eat half as much fat in man made partially hydrogenated oil. Mis-directed people will say I am stupid because bacon has more "trans-fat" or they will say "what is partially-hydrogenated?". Humans have eaten animal fat since the beginning of man kind. Partially hydrogenated oil's, however, were invented in the 1900s! They are less than 100 years old! Obviously humans didn't not eat the first animal in the 1900'a. Also, the news people talk about "maybe ban trans fat" and the argument against it, is to list foods that use partially hydrogenated oil, but rather than targeting this new chemical, they casually call it "trans fat" instead. Therefore, instead of actually talking about banning JUST Partially Hydrogenated Oil, they fool everyone into thinking they are going to ban donuts, breakfast foods and junk food. I'm sorry, but those foods are not REQUIRED to be made with partially-hydrogenated oil, they can easily be made with palm kernel oil.

[@pratofundo]

Jay H My guess: I know Hank has a degree in Biochemistry and he understand all the science stuff. But the simplification took place and became a little wonky. For most people won't be a problem, but… Palm kernel oil… well, yes, they could. But it has own issues. 1) Kernel oil still is a saturated fat and not that healthy. 2) The palm crops aren't very good for the planet as well. Native forests are being felled.

[@jasonlast7091]

This was super educational, all I ever see in the media are people labelling these things as good or bad but you've actually identified precisely what they are and why they are/'nt good for you.

[@juststeveschannel]

One of the best (clear & informative) quick summations/explanations on these topics I've ever seen. Guess that's why I'm happy to be a contributor (even if only a small one) to this channel on Patreon!

[@Atanar89]

Even though you said it ten times, I think it's very good to mention that quantity matters as much as possible.

[@aliceparry3226]

A study done in Norway showed that the fat/carb ratio was not important in the long run in terms of weight and heart health, it was the quality of the food that you eat that made the difference. They also found a higher total fat intake had a protective effect on your heart. It's only one study, but I think it makes a good point. Worry less about what you're eating and worry more about the quality.

[@lagoonroom4600]

I knew trans fats were bad but not that bad!!!

[@andy56duky]

+Selina Cox trans fat = lower HDL, raises LDL, resulting in heart disease and increased chance of heart attack.

[@dynamicworlds1]

+Selina Cox Yup, since it doesn't really exist in nature, our bodies haven't evolved any clue what to do with it. (either positive uses, or protective measures) At least saturated fat has some uses, like helping with the absorption of certain vitamins, but trans fat is really just a harmful, synthetic additive with no real redeeming qualities. We were really better off just sticking with lard. It doesn't have a particularly healthy balance of fats, but at least your body recognizes everything in it. Short rule of thumb: -Unsaturated fats are like carbs and protein: just watch your calories, make sure you're eating a balance of the 3, and you're probably good. -Saturated fats have some benefits, but moderation is important. -Trans fats are terrible for you and don't do you any good.

[@FusionDeveloper]

+Selina Cox All partially hydrogenated Oil is a trans fat, but not all trans fat is a partially hydrogenated oil. Partially hydrogenated oil for a transfat, is more harmful than naturally occurring transfat.

[@Correctrix]

+Jake Underhill I don't get why people explain that like it's some revelation. If we entirely cured cancer, that would only be a reduction of five percentage points. I guess that means we needn't bother!

The More You Know

[@kyuah]

Very clear. There's so much noise out there and I was getting hopelessly confused. Thank you Hank!

[@oakleywarioe9937]

I would love to see more dietary science! this helped me a lot with deciding what to buy. How about one on the effects of adding small amounts of fruit juice to your water (lemon water) ive heard its good for your kidneys but im not too sure...

[@TrishRowdy]

+Oakley Wariner Good or not, it sure is delicious xD

[@dynamicworlds1]

+Oakley Wariner I doubt it has any significant effect directly (it's just heavily diluted fruit juice). That said, not getting enough water can be rough on your kidneys, so I expect it greatly helps people who don't get enough water normally by making it tastier so they do. It also probably reduces how often people reach for other beverages (many of which are full of stuff your kidneys then need to filter out of your blood). So, if you don't get enough water or want to drink less soft drinks, it's a great way to do that, but it's direct effect is probably insignificant (otherwise, lemonade considered extremely healthy for you).

[@XBXish]

+DynamicWorlds I drink water once per month or once per few months, you could say I'd die without fanta haha. Unhealthy I know, but it isn't a priority right now. Maybe later in life when I'm about to die or get fat.

[@aidanbk]

[@danielj866]

I've seen so many vids on this topic and this explains it the best. So clear. Thank you!!

[@TheHadesShade]

Good video, but as someone that had biology and is fairly interested in how what each kind of calorie does in your body and how it works. I haven't heard anything new in this video :(

[@SciShow]

+TheHadesShade kzbin.info/www/bejne/ZmHNk3qVmMt6q7M This video might be a good place to start in an understanding about how the body breaks down food into energy. I don't think the video is explicit about what the difference is between proteins, fats, and carbohydrates... but the short version is that each type of food is catabolized into molecules that can enter the cycle detailed in the video, along with some byproducts (like ammonia from protein). I hope that helps! -Sarah Meismer

[@TheHadesShade]

+SciShow ah thanks, will take a look at it!

[@VK-pk8uz]

+TheHadesShade Scishow is introductory, opening up complex subjects to the non-specialised among us. What you're looking for is far more in depth information, and will either require as little as a trip to the library, or as much as an enrolment at a university, depending on how deep you want to dive into it (:

[@drinkmoresoda]

You are a special snow flake

[@briank7784]

there is no difference between calories, calories are a measurement of potential energy

[@dude157]

This is the best explanation of what Fat is I have come across anywhere. Kudos.

[@mattlm64]

There's no reason to think saturated fats are bad for you as the evidence suggests they have no ill health effects and indeed the body can handle them just fine. Saturated fat is good for cooking as it is relatively stable. Polyunsaturated fat is the worst for cooking and is unstable. Oils/fats high in polyunsaturated fats should be stored in a cool, dark place, and consumed quickly. It is also deemed a good idea to balance omega 3 and 6. So different fats need to be used and cared for appropriately.

[@Hansblow12]

+Matthew Mitchell Thank you.

[@emilgallier]

+Matthew Mitchell I beg to differ. Tons of studies show that saturated fats have a very ill effect on cardiovascular health. Scishow agrees. Care to link to some studies suggesting otherwise?

[@QuantumOverlord]

+Adonis Not very good studies, the link between saturated fat and cardiovascular health is more tenuous than we thought. The one thing we know that is definitely true is that trans-fats are just awful and you should never consume them.

[@kenimus76]

ask heart doctors about endothelial function after a life time of bad omega 6 and 3 ratios. you will be singing a different tune.

[@kenimus76]

yup could not agree more.

[@philliptune]

Oh man, how awesome. I must have missed this episode last winter. Since my wife and I are making handcrafted soaps (and because I'm just a big nerd) I have been researching different types of fats, their qualities in soap and how they differ molecularly. This video is a wealth of knowledge. And I think I must have snatoms now!!!!

[@Devin888]

It's important to distinguish between dietary saturated fat and the saturated fat we "see" in our blood work. It's not intuitive but eating saturated fats won't increase that metric in your blood work. It's eating excessive carbohydrates that become transformed into saturated fat- that's the problem. This is the saturated fat that is observed in your blood work and is correlated with an increased likelihood of heart disease.

[@fleabags4589]

so explain why all the high carb low fat vegans are lean as and at the top of thier game when it comes to health and fitness.

[@armoda1057]

there are millions of non-vegans who are also extremely healthy...

[@fleabags4589]

Yes.but in studies done on large groups of people vegans were the only ones with a healthy bmi.

big fan of scishow , great video hank , keep em coming

[@frankydman]

3:24 Sci show, You are referencing the Lipid hypothesis, which has been revoked by numerous studies as being untrue. Saturated fats have no link to plaque build up or heart disease. In fact, the latest research has shown the top three causes of heart disease are high blood sugar, stress and smoking. All of these are things that happen to raise your cholesterol, which has supposedly been linked to saturated fats. Again this is untrue. There is a grain of truth though: plaque can build up in your arteries, but it is not made up of sat-fats, it is made of dense LDLs, which are made from refined carbohydrates. Dense LDL builds up in the arteries and that causes inflammation. Saturated fats do not cause heart disease; the study that made that claim was flawed and is no longer accepted by the scientific community. As for cholesterol, high cholesterol does not cause heart disease, otherwise Dwight D Eisenhower would not have had a heart attack with a cholesterol level of 165.

[@metalfuelandfire]

+frankydman This is correct though, It's not exactly true that LDL is made up of processed carbohydrates. The primary factor in manufacturing LDL is regularly over filling liver glycogen stores. When liver glycogen levels are full, remaining fructose gets manufactured into long chain triglycerides and because triglycerides are the limiting factor in the production of dense LDL, more LDL is produced. The primary source of fructose in the modern western diet is in processed carbohydrates. That's where the connection is. Of course glucose can also fill lever glycogen stores, but it's more likely to be used to fill skeletal muscle, and adipose tissue stores(depending on which are more insulin sensitive). The main point is that you ant to eat carbohydrates appropriate for your insulin sensitivity and activity levels and only consume fructose when your goal is to restore liver glycogen levels after a fasting period(sleep) or after intense exercise to avoid ketogenisis. Fat should be your final consideration after factoring in your minimum protein consumption in order to reach your calorie goals. Eating healthy fats like omega-3 from fish oil(DHA in particular) is a way to improve insulin sensitivity further and saturated fat overall is not dangerous when you're not overeating.

[@AA-ez9cn]

+frankydman The majority of the scientific establishment, as well as major health authorities such as the American Heart Association, still recommend limiting the consumption of saturated fats based on a wide acceptance that they contribute to heart disease, based on decades of research. There is plenty of controversy, but you are misleading people by talking about the matter as though it is done with and widely accepted as false when it clearly isn't. What's more - this sentence: "high cholesterol does not cause heart disease, otherwise Dwight D Eisenhower would not have had a heart attack with a cholesterol level of 165" - is a logical fallacy because it presumes that in order for high cholesterol to be ONE cause of heart disease it must be THE ONLY possible cause of heart disease. This is like saying that smoking cannot cause lung cancer because some non-smoker who worked in the radon factory died of lung cancer.

[@frankydman]

I'm not misleading anything or anyone. I only state facts, and If you look back through the history, and the studies done, there is nothing that supports the lipid hypothesis. The lipid hypothesis suggest two things essentially: eating saturated fats raises cholesterol, high cholesterol causes heart disease. Neither of these are true, because the study that put it forward was flawed. In the 1950s, biochemist Ancel Keys proposed the lipid hypothesis based on a "six country study" that included Italy, Japan, US, UK, Australia, and Canada. There seemed to be an obvious trendline, where Japan and Italy had low rates of heart disease and low sat fat consumption. and US with high fat intake, high hear disease. One problem, the "six country study" was in fact a TWENTY-TWO country study, and the results were all over the place. For example, Holland and Norway had high rates of Fat consumption, but little heart disease. Chile had low fat consumption, but a high rate of heart disease. But Keys wanted to make an impact, so he cherry picked his data and presented it as accurate. As for the "decades of research" by what do you refer? No study has ever shown a link between saturated fats and heart disease, while over 30 studies have shown that just the opposite is true. For example- Michael DeBakey, a world-renown cardiac surgeon, once did research into this hypothesis involving more than 1600 patients... and he found no correlation between cholesterol and heart disease. And my statement is not a logical fallacy; that is just the point; how can high cholesterol cause heart disease when clearly, Eisenhower had a heart attack with a cholesterol level of 165? There must be something else, and that something else, as shown by recent research, is inflammation of heart tissue due to a build up of dense LDL.

[@AA-ez9cn]

frankydman I'm not saying I disagree with you, but the position of most medical authorities does, right down to the American Heart Association. But as for the logical fallacy part - yes, I stand by what I said: that is a logical fallacy. If you're unfamiliar with it, I suggest looking up "necessity and sufficiency."

[@Kuchenrolle]

+frankydman I agree on what you say about the lipid hypothesis and get annoyed with talking about unsaturated and saturated fats as healthy and unhealthy, respectively, but Sedrin is right, your comment about Eisenhower is incorrect and this is a classical logical fallacy. Yes, there must be something else, but that doesn't mean that high cholesterol isn't *a* cause of heart attacks. Only if we knew that heart attacks only have one single cause (which we don't, obviously), then we could conclude that cholesterol can't be that cause, because we have encountered a counter example (assuming no measurement error). Here's a different example: The ground gets wet when it rains, but it also gets wet when someone washes their car. Now when the ground is wet, but it hasn't rained, I can't conclude that raining doesn't cause wetness of the ground. More generally, from A -> B (read: from A follows B) you can't conclude !A -> !B (from not A follows not B), which is the fallacy. You can only conclude !B -> !A (from not B follows not A), in this case meaning that a patient that doesn't have a heart attack can't have high cholesterol - and that doesn't make much sense here either, as you will agree, because all of these things are risk factors rather than logical necessities that can be tested this way. Sedrin, you're right, the authorities haven't changed their recommendations. A while back I saw an interview with the German food administration office on exactly this topic (blaing saturated fats and promoting high carb dietary regimes) and they said that they are obviously aware of these issues, but also of the very shaky current nature of food sciences and that they don't want to change their recommendations and confuse people until they are certain that they have to, which they don't think they do, still claiming that at least you won't get harmed from the "balanced" diet they are recommending. I don't agree with that attitude or their specific recommendations (I personally tend towards thinking of carbs as bad and saturated fats as good, for what it's worth), but then again I can basically take any position that I want on this and find evidence that supports it, because food sciences is just such a shitty field, largely built around correlational evidence, small sample sizes, short term experiments and terrible statistics.

Make one about carbs as well. When i quit eating them and increased my fat intake (by basically eating cheese and cream (no crazy processed stuff) i went from 100+ down to 80+ kg and i have a TON more energy and i feel really strong and healthy. Im not a slave under food anymore. I eat one to three times a day. It's very seldom im sick though i got a cold right now. But everybody is sick here now! Im a vegetarian since 15 years so i only eat this cheese and cream plus quorn and vegetables (mainly green and white ones). I want someone who isn't biased by tradition, culture or lobbyism to tell me this is bad, if it is. Different - yes. Bad - no ..? When i became a vegetarian (before it became a normal thing basically) people around me told it was the end for me .. im still alive and i have muscles (proteins wasn't an issue after all?). By the way, im not sure if it's because i have a dog and walk a lot, but i have a great condition now and can run fast and long with minor breathing. Before this i couldn't do either and with heavy breathing along with aching knees. You bet i become a bit defensive when someone speaks up against LCHF due to tradition, culture or lobbyism. I know how much it has helped me and i still see people suffering with unhealthy bodies and selfshaming when eating lots of carbs along with fat.

[@betaleftist9218]

interesting, I have always viewed high fat diets as unhealthy. there are quite a few studies that show low carb diets being very unhealthy, mainly because your body requires carbs for its basic functions. I would argue that a higher carb diet is better, if in doubt eat more fruit even though they are high carb.

[@pertaterful]

+hyperbolic fuckboi Carbs are not needed at all. You can eat zero carbs and be fine. Look it up!

[@vileguile4]

+hyperbolic fuckboi i haven't eaten a fruit in at least two years! The problem is that if you go above about 50g carbs the licht will not work. If you do that you'll gain a lot of weight fast. I've read you need about 25g carbs for your brain. I've never had to add any carbs to reach that limit and I've never felt that my brain didn't work because of eating too few. As I'm diagnosed both bipolar and Asperger I don't know if my brain acts differently though. I am very conscious about how efficient my brain is performing though and I can tell I've became me even more focused. Just as I started with lchf our head of "food and health" in our government came out and vaguely accused lchf for possibly being the reason behind an increase in strokes for males 30-40. No facts or studies to back that up at all. Maybe take a look at Starcraft and energy drinks.. This is what I m ant about tradition , culture and lobbyism. It's so corrupt. Sugars and carbs are such a huge deal business wise.

[@fleabags4589]

+Jon Vaillancourt You conveniently left out the fact that he was 117 kilos with a history of heart attacks.( which could have been why he fell)And the fact that his wife refused an autopsy.Yea fact checking is so hard.If his diet was so good then whybwas he so fat before he died?

Silly me didn't look at my subscriptions for a while and so didn't see this before my nutrition test. *sigh* Thanks Hank! This helps my understanding a ton.

[@Storebrand_]

INB4 vegans talking about "naturally alkaline diets" and avocados.

[@carsontroeh127]

+StoreBrand the prior is a buzzword that makes no scientific sense and is unfounded avocados taste fucking delicious though

[@Storebrand_]

Carson Troeh I hate avocados, they're slightly bitter and mostly flavorless to me... maybe I've just had shitty avocados.

[@carsontroeh127]

StoreBrand I like to put them on sandwiches, avocados alone are just kind of nasty.

[@garyermann]

+StoreBrand That may actually be a result of where you live. You can definitely tell a difference if you live near where avocados are grown, like in CA, than if you live in an area that has to have them shipped over long distances.

[@arandomperson86]

[@Chlomoetv]

It makes me so happy to see an endorsement of a thing just coz it's cool. You're like I have access to a medium of expression so here is a cool thing... love it.

[@TheThomasBarry]

So I know this is going to come up because this is the internet so here it goes: Fats are not found only in animals. When Hank says "fat" he doesn't mean the chewy stuff on the edge of a steak. He means the chemicals that he describes, which are found in more than just meat. There are even pictures used as examples as to where the different fats can come from and it includes peanuts and olives. So before you militant vegetarians or vegans use this video as ammunition for your 'cause', I'd suggest watching the whole video and actually thinking about it first.

[@ChetzNation]

+William Bradey (Test) It's true, saturated fats are not always on animals and unsaturated fats are not always from vegetables. Fish and coconuts for instance. Further, lean meat has almost no fat in it. In fact, eating only lean meat will make you starve to death in a process called "rabbit starvation".

[@ArkbladeIX]

the one thing vegetarians don't seem to understand is that no matter how many "benefits" they throw out, people won't switch to vegetarian because nobody gives a Fuck. Lots of people just don't want to think about it 24/7.

[@pampam3636]

Being vegan is an ethical choice. That's it. You can be healthy or unhealthy living either lifestyles. If you don't give a fuck about animals, that's your choice. I choose to give a fuck. 😊 #notamilitantkindofvegan

THIS is why I'm trying to go ketogenic. High fat diets help your brain functioning, satisfaction after meals, energy levels and much more.

[@jskratnyarlathotep8411]

how could it help the brain, if brain can not use fats as energy source? Eating little carbs makes your liver to deplete its carbs depot, because we are not very good at producing glucose from fats as quickly as brain requires

[@TheSaintlyPelican123]

My brain uses ketones extremely well. It has to, given that I consume very little in the way of carbs

[@RAHGOTS]

Lol, the source for saturated fat is so weak and funny to read. Summary: "Um, like we think saturated fat might be a little bit bad for you, maybe?" I think I'll stick with my butter and/or coconut oil and eggs. Though I'm cutting back on processed bacon.

[@piranha031091]

Having just gone through a two month intensive chemistry course, this was a lot easier to quickly understand than it would without it! Great video, and lovely to put a lot of the knowledge into better perspective!

[@celibidache1000]

Show me the evidence of saturated fat building plaque in the arteries. Show me one study. One. No? Well, that's because fat don't randomly float around the blood stream suddenly getting stuck in the artery. Get your facts straight, please.

[@InXLsisDeo]

I've read so much crap on the internet, like "safety belts are dangerous, therefore noone should wear them", that I am extremely suspicious about claims like yours. More often than not, those who make them have financial interests in confusing people, or they are simply trolls. As for saturated fat, I've read it may be linked with increase of cholesterol levels.

[@funkyweezy8071]

You searched for trans fats, idiot. Saturdated Fats are NOT trans fats.

[@InXLsisDeo]

FunkyWeezy Can you even read ? Literally my first sentence was: "I know you're gonna tell me it's trans, not saturated".

[@alquinn8576]

I basically eat sticks of butter in my diet over the last year. Results: my cholesterol is up, but only the HDL from 60mg/dL to 75mg/dL. All of the people I know with cholesterol problems 1) are obese and 2) eat lots of sugar.

[@casey-zd5mj]

yeah still what does that have to do with saturated fat? What your opinion is saturated fat is somehow the same as trans? like fuck off lmao

+James Mitchell I like the mental gymanist Vegans have to do to support their own agenda and belief. They can't just simply do something and be content, They have to misconstrude, Fabricate and cherry pick random articles that agree with them and fall into confirmation bias. Oh look, One random study says Sugar is a drug. www.nydailynews.com/life-style/health/sugar-addictive-cocaine-heroin-studies-suggest-article-1.356819

[@enclavebrandon3]

Jasmine Taulu I use often times low fat, Fetta Cheese in moderation on occasion. Not everything in nutrition is entirely bad for you. With a few exceptions, Things cooked in trans fat really, really are horrible.

[@enclavebrandon3]

Jasmine Taulu I'd disagree with you on that because of medical research documenting good cholesterol increasing from eggs.

[@enclavebrandon3]

Jasmine Taulu "No cholesterol is good" Yeah it is, Jasmine. Cholesterol is divided into HDL and LDL. LDL builds up Plague within your arteries, While HDL clears it and keeps it clean.

[@higurashikai09]

Well, that was a nice, fast and simple way of explaining fats. Thanks SciShow.

[@Romanticoutlaw]

fat is not the enemy. Carbohydrates and sugars are way less healthy for you comparatively

[@siramea]

+RebelWinterwolf I think both fat and carbs have had a bad rap, we need both but the important thing is getting the right balance

[@TheNordicfrost]

+RebelWinterwolf It's more complicated than this, but the general rule of thumb is: Eat carbs is you're going to do something that'll make you breath hard I.E. sprinting, HIIT's, etc. And eat fats for everything else. You don't want to eat carbs if all you're doing is sitting down at the computer for hours. Keep this in mind and you'll be good.

[@betaleftist9218]

completely wrong, sugar is the primary energy source and is more quickly metabolised. fat is more likely to be stored as body fat than carbs as carbs must be converted to fat. also fat is linked to more diseases than carbs hence why the ketogenic diet is an atrocious diet and why more high carbohydrate diet are linked with longer life span and better athletic performance.

[@kenimus76]

fruits veg starch beans .... bad for you? mmmmm no. unless you butter salt fry candy coat refine burn or cream.

[@kenimus76]

[@thordoomskullsplitter5124]

it's a myth saturated fat is worse for you

[@Try2K3tchup]

Unless it's from nuts and seeds

[@Try2K3tchup]

+Walter White saturated fat from animals increase cholesterol nuts and seeds don't.

[@Try2K3tchup]

+Walter White lol I'm not trolling. Just look at Michael Gregor he has tons of videos on nuts. Plus nuts have fiber, antioxidants, and good fats like poly and mono which can lower cholesterol while fats from animals raise not only that it comes with worse stuff like animal protein, cholesterol, choline

[@JD-yx7be]

+Walter White saturated fat clogs arteries and give you osteoporosis

[@thordoomskullsplitter5124]

+Jonathan Dittmar no it does not. saturated fat comes in many different lengths from a medium chain like lauric acid which the body may convert to monolaurin and has antimicrobial properties to a longer chain like stearic acid which is necessary for many metabolic processes essential to proper health. saturated fat is stable and improves your immune system, cardiovascular health, endocrine system and stabilizers blood sugar among many other things. but what it certainly doesn't do odds clog arteries and it definitely doesn't cause osteoporosis

[@lorenzog4545]

Thanks so much for making this video, now I have an quick, reputable source of information to show people who ask about fat! I'm a pretty big fan of nutrition and I'd love to see more nutritional videos on here!!
