So many people feel that their premature aging, this idea of them looking older than they feel like they should, is all related to bad genetics. But one of my favorite newsletters that you wrote was you talked about six things in particular that have strong evidence around them that are actually connected to premature aging and getting older.
Essentially, you found that your diet done the wrong way could make you look older than you need to look. Well, let's talk about one of the first things that you've talked about in your newsletter that can accelerate aging, which sometimes people and researchers called inflammation, right? So it's inflammation, it's aging you. in that process.
And this is the idea that is a big issue more in our country, United States, probably than your country, Denmark. And it's the role of a high sugar intake in the diet. What is the role with sugar when it comes to accelerating aging and making us look older than we really should be looking?
What happens is that you have this inflammatory response and there are certain foods that will increase the inflammatory response. And that will be high sugar diets, as you mentioned. So what happens is that it's kind of like sugary foods or sugary drinks will activate or lead to a process that is called glycation. So this process is when sugar molecules bond to our collagen and elastatin.
So that means that if we take too much sugar in, it would decrease this process of having a lot of collagen in our skin and also how elastic it is. So we can see actually from studies where they have looked, it's a new study that is published in the German network. It's a scientific journal. They looked into different kinds of diets.
So they looked into the processed diet or a diet where they eat a lot of processed food and also a diet which is more raw food like Mediterranean diet. And they compared the epigenetics in these diets and looked at more than 300 people and compared these and looked at the epigenetic changes.
And what they could see was actually that those who had a healthier diet, which was more raw food and not... More minimally processed. Yes, exactly. They could see that they had more collagen in the skin and they also had less changes in their epigenetics. So it means that they had more elastic skin, more collagen in the skin, and they also looked younger.
So the thing is that when you do this on a regular basis, you eat a healthier food, which is not processed, then you have less inflammation, and then you will also have more collagen in the skin. So this is also a lot to do with protein and we will get to that one.
But if you eat these kinds of high fat diet, high sugary diet, you will increase this process, which I just mentioned called glycation. And glycation is not something that we want because we age too fast in that way.
