jehova Can you explain this for us? I assume you were told the information I ask:
Were you told, what is Glucose?
"~Ose" is "~sugar", a hydrocarbon so "organic" chemical.
Of the several vegetable "oses" Glucose is
a sugar made within most plants as the base for their main structural material, Cellulose.
Were you told what is "corn-syrup"? Commonly but not only made from maize, hence "corn", it is a mix of plant sugars: glucose, fructose, maltose and saccharides. It can be processed to turn some of the glucose to fructose, making it taste sweeter. Presumably the lecture covered this?
What is "organic mercury"? Did the lecturer define that?
An organic compound is one based on the element Carbon, plus usually hydrogen and oxygen, so most biological compounds are organic.
Mercury is a metallic element locked up in Nature mainly in its ore mineral, Cinnabar, chemically Mercury Sulphide, which of course is not organic.
Plants can absorb some non-organic compounds including metallic ones. Indeed they need certain metallic elements, and so do animals including us (bones and teeth, for example, are made of calcium phosphate).
Not mercury compounds though, except perhaps accidentally in some way.
So were you taught how corn-syup might contain mercury? From spraying the source plants with mercuric pesticides? Or, from some study of crops in some specific area whose soil is naturally rich in cinnabar by regional geology? *
What is "everything"? I take this really meaning corn-syrup being a near-universal sweetener for manufactured foods and some home cooking. I.e. foods from fairly complicated recipes including sweeteners, rather than simply "processed" such as canned fruit, cut meat, table-sugar or basic bread. Plain white sugar is nearly-pure sucrose.
So what is the real link between corn-syrup and diabetes? If any?
Were you told what is Diabetes, and the significance and source of glucose in our bodies?
Glusoce is a sugar carried by the blood for use as fuel by the cells. Diabetes is the body's failure to produce the insulin necessary to regulate that blood sugar level. So how does eating something containing no glucose, such as a plant syrup modified to turn its glucose to fructose, "cause" diabetes?
Where does
our glucose come from?
We eat much of it, and what we don't ingest, we make internally!
We know plants make glucose to turn into their cellulose - a polymer of glucose, and the main compound of the bits of plants we eat. These are our "carbohydrates" in dietary terms, directly or via products like grain and flour.
We eat many carbohydrates including cellulose; the liver breaks them down to produce among many other chemicals, a sugar called Glycogen. It stores that and when necessary, turns it to Glucose, the our cells' fuel-sugar.
Insulin is produced by the pancreas to regulate the level of glucose in the blood within fine limits. Diabetics need carefully control what sugars they eat but although that would include corn-syrup, the syrup or lack of it cannot "cause" diabetes.
So corn-syrup could indeed affect diabetes already in progress simply by being sugars; though a poor diet excessively rich in sugar will encourage the disease to start by long-term over-doses of "oses".
The message seems we should rely more on the cellulose (glucose polymer), less on sucrose and raw glucose; and let the liver and pancreas decide on the glucose!
I Iearnt the above by a few minutes of simple but careful research on top of basic general knowledge. I wonder what the lecture was supposed to be about, and its educational quality.

*naturally...
Back in the 1980s, I think it was, well-meaning officials strongly advised the residents of the village of Shipham, near Briston in SW England, not to eat vegetables grown in their own gardens. The soil was rich in zinc and other metallic compounds by both natural processes and local, former mining waste. The locals showed the visitors the local grave-yard: plenty of octagenarians and nonegenarians who had all existed on their home-grown foods. The embarrassed officials discreetly left... The truth was the plants were not absorbing the zinc, arsenic, lead, etc., or at least not concentrating them in the edible parts.
