Study Finds the REAL Danger of Processed Food… and it’s NOT Pretty

there are people on the internet that'll tell you it doesn't matter what you eat as long as your calories are in line you can go eat donuts and it's not going to cause a problem I don't necessarily disagree entirely from a body composition effect I've seen people get fairly shredded eating donuts and protein shakes but what's interesting is what ends up happening to the brain and long term this is interesting what the combination of fats in carbs do to the brain is nothing short of unreal until you start looking at the science and the research then it becomes very real and makes a lot of sense you see carbohydrates and fats are nutritional opposites and believe it or not they have different effects on the brain no it's not like all calories are created equal in terms of the impact it has on regions of the brain and when you look at fmri studies like that are looking at the whole scan and looking at this whole piece it's very interesting so we're going to break down an interesting study published in the journal cell metabolism that looks at post ingestive signals and helps us understand why that donut is so much more alluring than just those Skittles alone or maybe just pure coconut oil and bacon right let's Dive In foreign [Music] off your entire grocery order through Thrive Market using that link down below they're an online membership-based grocery store so you log on

to your brain what is the level of satisfaction okay well these post ingestive signals are independent of any other signals independent of uh effects on like glp-1 and gut hormones and things like that these are specific signals that are kind of regulated in the brain okay what this study ultimately ended up demonstrating is that car carbohydrates and fats really trigger completely different signals very different things altogether however when they're combined you're going at these two Avenues independently to form one very solid potentially bad habit you see we have to look at this somewhat logically the combination of fats and carbohydrates in nature isn't really existent I mean in small degrees yes right but the likelihood of over the last Thousand Years up until we've had more modern technology and Logistics and travel and everything the likelihood of getting 50 grams of carbohydrates along 50 grams of fat in one sitting was kind of not really going to happen right like you're not typically finding a bunch of tropical fruit alongside a bunch of maybe macadamia nuts this is not really happening that way a especially when it comes down to sugar and super high glycemic spikes so this is a relatively newer thing for our body to really adapt to and for our brain to adapt to now the really solid thing is here is that it's not bad to consume a little bit of fats and a little bit of carbs together but the problem is when you start consuming copious amounts of them that are unnatural right this is where the study gets interesting so what this study actually did is it took a look at subjects and had them come into a lab have them come into the lab fasted and then they fed them a standard breakfast after they fed them the standard breakfast they waited for three hours and then at the end of three hours they showed them pictures of food some food was pure carbohydrate some food was pure fat and some food was combinations of fat and carbohydrates in various forms they gave the subjects five euros in this case to spend they basically set up a bidding war on these Foods okay and they were satiated because they had breakfast right what do you bid on what would you want well they found dramatically people wanted the fat and the carbohydrate combination Foods at first glance you're like yeah that would make sense because fats and carbohydrates do sound better that sounds like a better food than maybe just pure sugar or maybe just pure fat but that right then and there you realize that's a problem right we've adapted to this as normal but that's not necessarily normal so what happens well when they put them under fmri Scan they saw that having the fats and carbohydrates together or Desiring them just lit up portions of the brain that are associated with addiction in this particular case the media dorsal Thalamus and also the codal putament which we'll talk about in just a second so lit these areas of the brain up well what does this really mean well the kadai pudiment that is a region of the brain that actualizes goal-like behavior like operating towards a goal into habitual behavior that can even override things I think we're describing addiction so basically when you see this this is the same kind of patterns that we notice in fmri scans of addicts so when you have fats and carbs combined it highlights that portion so much more because you're coming at it from different angles for all intents and purposes you are accentuating different reward signals the reward signal that you get from carbohydrates or glucose is totally different than the reward signal you get from bacon so it's interesting because when you look at people that do a lower carb protocol they preach about their bacon and their cheese right they gravitate towards it because they are still satisfying a reward signal okay they're satisfying that system activating that caudite putnaments that region of the brain to a certain degree and then you have people that I just crave Skittles I crave Sour Patch Kids I crave sugar they're activating a different pathway that's still probably to a certain degree lighting up that cardiac putnaments but then when you put it together it's like boom it's like a Christmas tree lighting up and it's so clear to see in fmri the combination of fats and carbs are not something that we are really designed to be consistently consuming again having a small handful of nuts with a small handful of fruit like we might find in a realistic situation in nature is perfectly acceptable and the body can handle it there was a study that was published in the proceedings in the National Academy of Sciences of the U.S that looked at Network stability for people that were either fasted doing a lower carb diet like a ketogenic diet or people that had a standard American diet okay they found that ketones when they were doing a lower carb protocol ended up improving Network stability basically the brain was able to send signals throughout different regions a lot clearer the moment that glucose was entered into the equation it altered this it shut it down this isn't to say that glucose is bad this is to ultimately say that the brain especially once fat adapted prefers to run on one fuel at a time and when it has to switch back over to another it has a ramp up period it's difficult further indicating once again that when someone is maybe ketogenic because from any kind of my like you know 500 years ago a thousand years ago we're out just hunting for survival we go through periods of time when we're in ketosis the brain operates in a stronger way then you have glucose or whatever because maybe you ingested some fruit and it sort of pacifies the brain and allows you to calm down and allows it to get out of that super highly operative State and you can relax the sleep because you've been eating you've been fed so you see what I'm saying here ultimately we do have to look at this big picture of when the body would process what so maybe you shouldn't be combining the Skittles with bacon it kind of sounds good anyway I'll see you tomorrow
