Use pure Glucose?

Its not the sweets that I break down for, its cured meats and cheeses, and occasionally I want grains really badly.

> occasionally I want grains really badly

Is that because you are in a low carb diet? A few friends went that way and mentioned some craving for grains

Table sugar is entirely made up of sucrose. A polymer which is composed of one glucose molecule and one fructose molecule. Fructose is also in most fruit sugars. Honey is one of the worst offenders from a natural source. Finally corn syrup is the absolute worst. Avoiding refined sugars in general is a good thing, but removing fructose completely would require not eating any fruits or berries either. The rule of thumb…

I think most Americans are doing just fine with high fructose diets. However, there have been a lot of studies coming out, that seem to be suggesting there is some danger of obesity after a certain low carbohydrate diet or skipping carbohydrates altogether, as these diets tend to spike blood sugar rapidly. The most interesting is a study in humans, that showed a significant increase in blood glucose when carbohydrate…

Which study are you referring to here?

I eat a lot of honey, and am a huge fan of maple syrup. I love maple syrup, but I eat it in moderation. I eat it in smaller portions of about half cup daily but can have as much as I want. It's good on it's own as an energy source, and can be used as a natural sweetener. Also, I like to eat my whole grain breads with maple syrup as well. It adds flavor to them, so maybe I should add some! It's easy to eat, and is eas…

That is a lot of pure carbs and no protein or fat. All of your comments seem to be suggesting this diet. "Whole grain" is the only healthy part of your comment.

I think (hope?) the user is trolling.

> rare and seasonal in nature I don't know what else to add. You've gone too far off the path. It's pretty simple what OP wrote. Makes a person think about nature, evolution, adaption, is-this-healthy. Ok?

You know what it makes me think? You're chasing extremely marginal gains in life expectancy. Yes, there's a good chance that in the caveman days I would only have had honey in rare circumstance when I found a good beehive and had time to process it. It would have been consumed fairly quickly unless I had extremely advanced levels of time preference and self control. I also would probably have been dead by my mid-30s.…

> What path, friend?

A person says, "honey seems like a rare seasonal treat in nature for most humans. Should we be eating a lot of it?". Same question gets asked about soy, gluten, beef, etc. It's more of a nutrition observation. It just seems like you missed the whole spirit of the thought.

Not terribly low. I eat plenty of root vegetables. Sometimes sourdough just smells really good.

High-fructose corn syrup is not a misnomer. It is in contrast to ordinary corn syrup which consists almost entirely of glucose along with smaller amounts its oligo-saccharides (e.g. maltose, etc). Corn syrup generally contains no fructose. To be precise, HFCS-55 is 55% fructose. Commonly used varieties of HFCS include HFCS-42, HFCS-55, and HFCS-90, containing the percentages of fructose indicated by the number, thoug…

I think you missed the point, moreover the article you cited actually supports the parent comment (note the italicized sentences). > However, diets containing large amounts of sucrose, high fructose corn syrup, or fructose alone, overwhelm the ability of the small intestine to metabolize it all and under these conditions a significant amount of fructose is then metabolized by the liver and to a lesser extent by other…

I suppose that depends on what you believe the point is.

The opening assertion was that high-fructose corn syrup is a misnomer. This not a historically accurate statement. Disregarding any erroneous conflation of high-fructose corn syrup with corn syrup (of the only type that existed prior to the invention of what is termed high-fructose corn syrup), high-fructose corn syrup is most assuredly "high" in that it contains a "high" percentage of fructose (40-90%) in comparison with the previously existing corn syrup which contain 0% fructose.

It is spurious to hold to a vague definition of "high" that can only apply to concentrations somewhere in excess of 90%, lest we find ourselves unable to refer to water containing 0.5% lead by weight as having "high" levels of lead.

That said, I concur with the assertion that significant consumption of fructose in any of the commonly available forms, including as a component of sucrose, that do not substantially moderate the rate of its absorption (e.g. such as a dietary fiber-based structural matrix) carry an associated negative health risk.

It is accurate to say that sucrose becomes the equivalent of "HFCS-50" upon contact with the enzymes which line the inside of the small intestine.

Ah, another meaningless nutrition epidemiology study done on rats and ex vivo cells in a dish that tells us precisely nothing about how the health of actual humans is affected (if at all).

It's further confirmation that the highly addictive toxic white powder pushed on the public by evil cartels we should really worry about is not cocaine, but sugar. Do you drink soda? Put sugar in your coffee? Well, the first step is admitting you have a problem.

You dont have to be a genius to conclude that eating empty calories of anything is bad for you. But the parent poster has a point.

But don’t all other primates eat lots of fruit? Why are humans unique?

Raw fruit isn't a problem, not even for humans. Products where "sugar" is replaced by fructose or other, simpler sugar variants is. Various sugar substitutes are added to e.g. canned fruit in "juice" which is mostly some kind of sugar. Which lets marketing say "less sugar" ... And "high fructose corn syrup" is ... almost pure fructose. Which the human liver can only process a limited amount per day. Anecdote: a young…

The most common form of HFCS is less than half fructose.[1]

>I think most Americans are doing just fine with high fructose diets. Most Americans are overweight. I wouldn't call that doing fine.

Well, they're prepared for a famine, and since you can live till your late 60s or later while being horrendously out of shape, "fine" is a relative thing, no?

Sure, I guess that is technically considered living.
