how do high density lipoprotein leads to diabetes?

Q. how do high density lipoprotein leads to diabetes?
what are the scientific theory behind it?

A. high density lipoproteins DO NOT lead to diabetes! HDL is the "good" cholesterol --- your question is totally wrong!

Type 2 is not "caused" by being overweight! Many factors are involved in the development of type 2 DM, including genetics, lifestyle, and medications. the idea that being overweight causes type 2 DM is an unfortunate piece of information, Obesity is a risk factor but is NOT the cause!

Of the following cell types, the greatest concentration of high-density lipoprotein (HDLs) would be associated?
Q. Of the following cell types, the greatest concentration of high-density lipoprotein (HDLs) would be associated with ________ cells
A) skin
B) muscle
C) connective tissue
D) blood
E) liver

A. Though these proteins that transport cholesterol are in the blood...
the liver is the one that makes this cholesterol, if it isn't obtained
from the foods we eat.

The LDL, which is considered the bad cholesterol...is the lipo
protein that transport cholesterol out from the liver to the cells
and is known to clog the arteries.

The HDL is the lipo protein that transports
cholesterol back to the liver...so since it is the HDL....
then I believe the answer would be the liver (E).

This seems kind of tricky...considering the cholesterol
is transported in the blood...so it might also be D) Blood
since blood tests are taken to determine how much
HDL and LDL are present.

Hope this has been of some help. Best wishes

where is Low density lipoprotein (LDL) & High density lipoprotein (HDL) synthesized?
Q. Could you also let me know
1. HOW and WHERE they are removed from the bloodstream and
2. Dietary and lifestyle factors that may increase or decrease the amount in the blood (please explain).

I have been researching but I didn't find much.

A. HDL cholesterol "scavenges" your bad cholesterol and helps to eliminate LDL from the body. The only nonpharmacologic way to increase your HDL is to exercise.

Ingesting more soluble fiber lowers your LDL cholesterol because soluble fiber binds bile in the GI tract and it gets eliminated. Bile is synthesized using LDL, so that's why you sometimes see advertising on the side of quaker oats that they can lower your cholesterol. I believe the recommendation is to get 20-30 g of fiber / day.
