Actually diabetes in the US for example is closer to 12% with another 1/3 of the population undiagnosed simply because they've not been tested and almost 50% of the population are insulin resistant and diabetes and IR are the leading cause of death, blindness and lower limb amputations.
Most of this comes down to diet and lifestyle. Americans consume over 60% of their calories from ultra processed foods and closer to 80% if we include processed food and over 40% of the population are actually obese with another 30% that are only classified as overweight, so basically 70% of the US population is overweight or obese and where 85% of that population have either insulin resistance or diabetes. Diabetes is a blood sugar, insulin problem and with continual spiking of blood sugar from this type of high carbohydrate diet multiple times a day and then over the course of years eventually the whole system breaks down and the beta cells in the pancreas just can't accommodate the amount of blood sugar that needs to be removed in a timely fashion. The more Italy adopts this lifestyle the more diabetes and obesity your going to see.
"Foods" engineered to be hyperpalatable is the foundation of ultra processed foods which typically are a combination of carbohydrates, sugar, fat and salt which triggers the brains reward system which interferes with the body's ability to regulate appetite and satiety which encourages excessive eating, this isn't rocket science, it's a well documented fact and has been for decades. Our evolutionary adaptive abilities that helped us survive are now turning out to be our nemesis, isn't that special.
Wow, those are very high percentages.
A common factor here is that many people who have diabetes 2 are not actually overweight, apparently we have about 12% of the population obese and 36% just overweight.
Our problem/bad habit here is eating too many carbs, l don't think we exaggerate too much with ultra-processed foods, but maybe with cured meats, yes. That's why we have a lot of people (not overweight, like me) with high cholesterol levels, although this can be hereditary. I don't eat salame anymore.
This is beginning to sound like a nutritional thread.
