How can it be addictive (as drugs) if it can't pass to the blood and reach the brain? It will be broken to fructose and glucose by sucrase at cell membrane.
sucrose (sugar) is 50% glucose and 50% fructose
No, it is single molecule. To break it into glucose and fructose you need sucrase, invertase or hydrolysis.
high fructose corn syrup is 45% glucose and 55% fructose
I'm not very familiar with corn syrup, we don't use it often in Russia, but as I understnad it is specifically fermented to get higher percentage of fructose. But it is definitely not sucrose.
For the purposes of this discussion, I'm treating them the same as they make my point.
But they are not the same. Sucrose breaked down to fructose and glucose with sucrase on cell membranes. That glucose immidiately absorbed into blood. Fructose first phosphated in liver and then after long complex process transformed in glucose. Free glucose could be absorbed everywhere, but not so fast as from sucrose breakdown.
So, there are three different processes for three different substances.
I'd say ketosis is "natural" in that it was built into our bodies to survive during times of starvation.
Yes, just like other failover mechanisms. But using it as main energy process is not in our habit. Moreover, when there is lack of glucose, our body more likely began to synthesise it from other substances (in liver, f.e.), than to completely switch to ketosis.
Senior citizens in the US will tell you there weren't as many obese people when they were young as there are today.
There was not many obese people in USSR. And that is not because of famine, may be we had a little choice here, without thousands of sausage or cheese variants, but we always had enough food. It was not very tasty or very diverse, but basic Russian cuisine was completely accessible. Nobody starved. There was period of USSR destruction, when some types of food disappeared, or people just had no money to buy food, but fortunately it was not long.
We got spike in obese people when food from corporations come here, and that corps began to buy out Russian food enterprises and introduce new technologies.
Now Russia consume noticeably less sugar than in USSR times, but the number of obese people is definitely grown in last 30 years.
I'm shure that the true reason for obesity is an unnatural additions corporations use in food production.
That is not science at all. Dopamine levels does not mean addiction. It just mean that person have positive emotions, nothing more. Fact that cocaine rise dopamine level does not mean that everything that rises dopamine level is something like cocaine.
Looking at nice girl could rise dopamine levels to the sky. Does that mean that nice girls is more addictive than cocaine?
Russian sugar consumption per capita is less than USA but still elevated
In USSR sugar consumption was ~50kg
Regarding obesity, it's not just sugar: starchy foods like bread, pasta, potatoes, etc break down into glucose. A pryaniki could be "bad" due to the sugar plus the flour (if one eats too many).
Obesity cause is a malfunction of body systems, not the starch or sugar, or some other common ingridient. Otherwise, everybody would be obese, but this is not what we see around. Obese people are just broken and have to be repaired, others eat the same and never become obese. Some special diet for obese is just elimination of symptoms, not fixing the real cause of obesity.
I like pryaniks, I eat them a lot, I eat a lot of sugar, starchy food, bread, meat, etc. and I am definitely not a sporty person, just ordinary daily activity of suburbian habitant. I spend a lot of time pressing keys on computer keyboard and all that does not make me obese. This does not make obese most of my colleagues and friends who have same lifestyle. Only few ot them have excess weight, so it is definitely not a diet or lifestyle, but something else.
