More specifically, you want help with What Sugar Does to Your Brain & Body: The Truth About Sugar?

if I were to just tell you that sugar is bad I’d be preaching to the choir right we all know that we know that it’s not good for us we know that it has a lot of different effects within the body but in typical Thomas Toole our fashion what I want to do in this video is break it down a little bit more I want to help you understand what sugar does inside the body and also what sugar does inside the brain because here’s the thing sugar is not just basic glucose sugar or refined sugar is entirely different it does something quite different in your body and it’s important that you understand what’s happening so first off let’s start with what it does in the actual body and then we’ll break down what it does in the brain first and foremost you hear me talk about sugar and its relationship with inflammation before I go into detail about that I have to give you a quick summary of what inflammation is you see inflammation is a very simple process that occurs within the body we need it to function we need it to heal whenever you’re done working out inflammation is triggered whenever you’re sick inflammation is triggered whenever you have any kind of infection inflammation is triggered the problem is that inflammation when it’s chronically elevated becomes a very big problem because your body is in a heightened sense of alert so basically it’s trying to fight something off but when we consume sugar we have a massive increase in inflammation there have been studies that have proven that but it all has to do with something known as advanced glycation in products what these advanced glycation end-products are are basically a response to a reaction with sugar within the body see we always have a certain level of proteins and fatty acids that are flowing through the bloodstream doesn’t matter if you’re fast it or not your body is breaking down fats it’s breaking down proteins and it’s allowing those particles to flow through the bloodstream well when you consume sugar that sugar responds with the proteins and with the fats and it creates a little bit of a reaction and this reaction creates these advanced lication in products which I’m going to refer to as a G es these AG es are what trigger inflammation within the body you see studies have actually shown that when you consume 50 grams of sugar which is a modest amount typically what you’d find in a soda you’re going to have an increase in c-reactive protein levels within 30 minutes and those c-reactive protein levels are gonna remain elevated for over two hours this has been proven time and time again giving us a solid link between sugar and inflammation but what else do these a GE do these advanced glycation end-products well unfortunately they react with aging components within your body these AG es breakdown collagen and they break it down quite dramatically which means that if you’re consuming a lot of sugar you probably notice that your complexion isn’t very good you probably noticed that you’re getting wrinkles a little bit early on in life you probably noticed that you don’t recover as well when it comes down to your skin well guess what it doesn’t stop there you have a lot of collagen in your joints as well so if you’re someone that’s dealing with a lot of joint pain in addition to the inflammation that is caused by the sugar that occurs in your joints we also have the breakdown of collagen which is making it so your joints can’t recover these AG es are not good it’s not a normal response that should be occurring within the body when it happens it should be happening at a very small amount but we’re consuming so much sugar it’s a huge issue okay now let’s move in to the arteries in the heart for a second here’s the thing so much of the common media and so much of what we hear today all tells us that fats are the enemy when it comes down to atherosclerosis when it comes down to high blood pressure when it comes down to any kind of heart disease well a lot of us are starting to find now and researchers are starting to conclude that an selkies wasn’t exactly correct when he first said that cholesterol was the issue when it comes down to heart disease you see inflammation is truly the issue and a lot of doctors and researchers are starting to see that now you see what happens when we have an insulin spike that occurs from consuming sugar we have cells in our arterial walls that actually harden up so the arterial walls themselves become more stiff they become more hard which means that they don’t flex as much when they don’t flex as much it means that’s more resistance against the blood which means higher blood pressure which also means there’s less flex which means it’s easier to end up having a clot or have atherosclerosis we don’t want that to happen obviously a lot of the reactions with atherosclerosis or any kind of blood clots like that a lot of times occur simply because of inflammations response to LDL or inflammations response to sugar of course within the blood stream now studies are now showing that there is a solid link there but again I’m preaching to the choir so let’s move into the next phase that’s where I want to talk about the brain see the brain has a bigger response to sugar than the body but as we well know the brain is sort of the precursor to everything is going to happen in the physical body after that let’s first start with a day I don’t know if you knew this or not but sugar responds in the brain similar to heroin and similar to alcohol in a lot of ways it has to do with affecting the dopamine receptors in our brain we have a high level of what is called dopamine D sensitivity that occurs so every time we consume sugar we get a dopamine rush we get a little bit high from it and that’s why it feels so good and that’s why we crave it well that desensitization occurs which means that you end up needing more and more sugar to get the same result well it doesn’t stop there we actually have opioid receptors in our brain these are receptors that usually are triggered by things like heroin or morphine well guess what they’re triggered by sugar as well so we’re now finding through research that sugar has gram for gram almost as powerful of an effect on those areas of the brain as most street drugs do that’s pretty darn powerful now to add insult to injury we have cross sensitization with alcohol and amphetamines when it comes to sugar which means sugar can actually help you build a tolerance to alcohol and build a tolerance to amphetamines now I guess if you’re trying to build a tolerance to alcohol that’s not a bad thing but in reality that means that we’re affecting the same area of our brain definitely not good alright let’s move into depression this is a big one because a lot of people will bring up which came first the chicken or the egg does a depressed person or a person that has a mood disorder go to sugar because it helps them feel better or does someone that consume sugar acquire symptoms of depression or mood disorders well in 2017 study in the scientific journal took a look at that so this 2017 study took a look at just that it broke down which came first the common mental disorder or a sugar addiction they took a look at twenty three thousand two hundred and forty five people and they have them take assessments okay assessments that looked at their mood and then assessments that log to their food or their sugar intake but what they found is that there is no link between the common mood disorder and reaching for sugary sweets but there was a link between consuming sugary treats and then acquiring mood issues therefore researchers were easily able to conclude that sugar does indeed trigger the common mood disorder and potentially even depression now I know that this isn’t too much new news for you but I wanted to be able to break it down in some science that you understood I’m not saying that you need to go and throw away everything that has any trace of refined sugar in it but I am saying that you do need to start making a little bit more of a concerted effort to avoid that because it does have a direct impact on your aging and it does have a direct impact on your body composition in a lot more ways than just a potentially bad starchy carbon so as always keep it locked in on my videos and if you have any ideas for future videos regarding inflammation ketosis fasting you name them below I always look at them always get awesome ideas from you guys so I will see you in the next video

What Sugar Does to Your Brain & Body: The Truth About Sugar – Thomas DeLauer

Sugar’s Effect on the Body

1. Inflammation, Joint Pain, and Aged Skin

High sugar foods have been shown to lead to inflammation in the body, which can increase the susceptibility of individuals to these diseases and can also worsen symptoms for those already suffering from them.

Scientific surveys have also found that increased sugar consumption, in particular sugar filled soda, may increase the risk of developing rheumatoid arthritis and may worsen symptoms (RA). 1,2

The inflammation caused by sugar not only impacts our health, but also our skins look and feel.

When sugars attached to proteins in your bloodstream, advanced glycation end products, or AGEs, are formed. These harmful molecules age your skin through causing damage to the elastin and collagen. This leads to more wrinkles and sagging skin.3

2. Heart Health

When you consume simple sugars, the boost of insulin in the bloodstream can cause artery walls to grow faster than normal and lose their elasticity.

Over time, this can lead to heart attacks, stroke, and heart disease.

Additionally, research suggests that consuming less sugar may help to lower blood pressure, which is a major heart disease risk factor.

Studies have found that those who eat a lot of sugar (25% or more of their calories as added sugar) are twice as likely to die of heart disease when compared to those who consume 10% or less of their total calories from sugar.4

Sugar’s Effect on the Brain

1. Addiction

Sugar shares many similarities with drugs of abuse.

In rat studies sugar has been found to lead to signs of dopamine sensitization and opioid dependence, including cross-sensitization with alcohol and amphetamine, neurochemical and behavioral signs of withdrawal, and alterations in dopamine and my-opioid receptors.6

When you eat sugar, you brain releases dopamine, a neurotransmitter that causes you to feel good.

Whole foods, even fruits, do not cause the release of the same quantity of dopamine as processed, sugary foods, such as donuts.

As time goes on, your sensitivity to dopamine decreases, causing your brain to need more to feel the same amount of pleasure.

This is what causes addiction cravings to sugar.

2. Depression

Studies have linked high sugar consumption to depression risk in adults.

This leads to the following question: does sugar lead to depression, or does depression influence sugar intake?

Case Study: Sugar Impacts and Adverse Effect on Long-Term Psychological Health 7

In a 2017 study published in Scientific Reports, researchers sought to determine if sugar consumption leads to common mental disorder (CMD) and depression or if the reverse is true, that individuals suffering from CMD and depression are more likely to eat sugary foods.

Through analysis of repeated measures for 23,245 person-observations from the Whitehall II study, mood was assessed using validated questionnaires and diet through food frequency questionnaires.

Researchers found that neither depression not CMD predicted the intake changes found during their analysis where positive associations between sugar consumption and CMD and depression were found.

This led the researchers to conclude that dietary sugar intake has an adverse effect on long-term psychological health, including both CMD and depression.

So How Much Sugar is too Much?

Currently the average adult consumes roughly 22 teaspoons of added sugar per day, which is far more than the American Heart Association recommends: no more than 6 t/day for women and 9 t/day for men.5

Remember that this is added sugar, so not the natural sugars found in fruits,
