You say sugar, but are you referring to glucose or fructose?

There is a meaningful amount of scientific literature connecting fructose and inflammation.

The AVERAGE human can only digest about 30g of fructose a day. Some substantially more, some substantially less.

A can of soda or three apples is about 30g of fructose.

Inflammation (high- and low grade)then being a second step linking to anxiety.



I am talking about the sugar in sweets. My daily apple does not appear to heighten my anxiety.


I have heard people say that eating fibers together with fructose(like when eating a apple) reduces the impact of fructose, as fibers create a lining on the gut wall reducing the absorption rate.

Sounds reasonable. But i have had a hard time finding evidence verifying that hypotesis.


Its in most nutrition textbooks, it's partly why fiber is so important.

Eating fiber with any carbohydrates reduces the absorption rate. It's partly why eating an Apple is better for you than eating a lolly despite both being high in sugar.


I think you have to look for "glycemic index" and learn about its mechanisms, which in your defense is not an obvious term to search for.


I’m not sure about that mechanism, but the impact on blood sugar is quantified as “glycemic index” and “glycemic load.”


Serotonigenic microbes digest fiber into feelgood neurotransmitters.

You're welcome.


i'm pretty sure this saying is well agreed upon by the mainstream medical community. (not a medical pro myself, but follow a lot of articles and podcasts from mainstream sources)


Athletes consume 50g of fructose (and 50g of glucose) per hour. It's actually fairly easy to train yourself to this level.


> Athletes consume 50g of fructose (and 50g of glucose) per hour

...while actively competing in endurance events. They don't do this while sitting on the couch in the evening. And it's very specifically only endurance trained athletes who do this, sprinters would never need to consume that much sugar.

It's a valid point though, a sugary snack or sports drink directly before hitting the gym for a hard workout session is probably fine, as long as your blood wasn't already saturated with glucose from earlier sugary foods, and as long as you don't have insulin resistance.


Sure, but that all has nothing to do with digestion, that has to do with blood sugar levels and what your body does with the energy afterwards. Digesting 30g of fructose per day is not any kind of biological limit, in contrast to what GGP claimed.


It's a biological limit without long term health effects, unless you're burning it off with intense exercise.
