Why are fruits and berries healthy, even though they are mostly just sugar?
-
If I remember my highschool biology correctly (which I probably don't, so take this with all the grains of salt), natural sources like berries, fruits, etc... create natural glucose which is what every living organism (including us...use for energy). Meaning when we eat berries and fruit, that natural glucose doesn't need to be converted or processed in order for our body to make use of it. That also gives it a more stable effect in our system.
Refined sugars, on the other hand, need to be processed into glucose before it can bind to (oxygen? I think?) and pass into our bloodstream. That process leaves a lot of junk leftover which can have detrimental effects.
Again...I'm trying to remember a 35 year old highschool biology course, so correct me if I'm wrong.
close but not quite
All carbohydrates have to be converted into glucose. Your breads, pastas, starches, etc
All forms of glucose can be used directly, without the conversion. But that does not make them healthier by any stretch

Fructose is the element in sugar (Sucose) that actually taste sweet, it is also the part that is unhealthy. it acts somewhat like alcohol.
Giving similar problems and can also cause dependency.If you want to know the basics about sugar I don't think there is much better info than this out there, absolutely worth a watch:

Glucose by itself is also very unhealthy

Whole fruits are a treat that can be tolerated by a healthy person in very moderate quantities. Think about the quantities you would get if you went out physically picking fruit off of a tree. So not a big bowl of easy to consume fruit from the grocery store, but when you put the physical effort in.... It's ok
There is no essential nutrition in fruit, historically, the role of fruit was as a fattening device before winter. An opportunistic caloric boon.
The biggest argument in favor of citrus fruits is there vitamin c. In the modern dietary context with really high blood glucose levels there is competition for the natural vitamin c pathway, the glut4 receptor. Citrus, by virtue of flooding the body of vitamin c, gets enough vitamin c into these cells and wins the competition with the blood glucose levels.
If a whole fruit offsets something worse you could eat, like a candy bar - then yes it is healthier then a candy bar, but it's also healthier then a cigarette. That doesn't tell us much about its essential levels of "health" in isolation.
Tldr: whole fruit is a sometimes treat, but it does not contribute to your health.

Because sugar isn't unhealthy in the first place, you'll die without any sugar.

Fructose is twice as sweet as Glucose, and while we do use Glucose for energy the same is not true for fructose, and fructose is way way more harmful.

https://en.wikipedia.org/wiki/SweetnessSure, but the fact remains that glucose is sweet.
Unless you have FLD the vast majority of metabolic damage is from persistently elevated blood glucose. There is no dietary requirement for exogenous glucose in our food.
So is 100g of fructose worse then 100g of glucose? Sure, but glucose is still quite bad and abundant in most people's diets.

I couldn't be more wrong if I tried

I'll grant you my position is unpopular, but I haven't seen any data indicating it is wrong.
People can, and have, lived long happy lives without any fruit.

Sugar: THE BITTER TRUTH
Robert H. Lustig, MD, UCSF Professor of Pediatrics in the Division of Endocrinology, explores the damage caused by sugary foods. He argues that fructose (too much) and fiber (not enough) appear to be cornerstones of the obesity epidemic through their effects on insulin. Recorded on 05/26/2009.

He is so well spoken, and his work is very impactful!

Help me understand your position then. What was wrong about my original comment that fruit is a treat best enjoyed in moderation?
