You sound like you are a paid shill. I know that you aren't, which disappoints me further, because I'd like to think that people are capable of educating themselves instead of spreading misinformation. On your first paragraph, pondering whether sucrose breaks down into fructose and glucose immediately: No, it doesn't. HFCS makes sugars available to the bloodstream sooner, causing larger swings in overall blood sugar…

First of all, I tend to agree with the sibling posts accusing you of failing to maintain scholarly decorum. The "paid shill" remark was uncalled for, even if I tend to agree with your criticisms (at least, all but the most crucial one). > pondering whether sucrose breaks down into fructose and glucose immediately: No, it doesn't. Can you substantiate this further (say, with an in-vivo sucrose half-life)? I don't have…

In the paper, they state that they did daily measurements of chow and sugar drink intake. So the intake was mostly unregulated, but it was measured.

I don't understand the mechanism here. I thought sucrase, the enzyme that breaks down sucrose (table sugar) into 1 fructose and 1 glucose (same as HFCS), acted almost immediately -- at least on the timescale of nutrient absorption. Is it just short circuiting our sense of satiety? Maybe the raw fructose makes things sweeter and stimulates reward centers better? I wonder where honey falls in all this since it has high…

The problem is not exactly solved, because it is not clear what the farmers should grow in the place of corn. As a grain farmer operating in a country that does not have subsidies, we still end up growing corn, even if it results in a loss. Bankers prefer to see a loss than to leave the land lay fallow, and there are not many famers who can operate against banker's wishes in such a capital intensive business. You can…

As long as the subsidies exist, there is no capitalistic incentive to solve the problem. If a solution NEEDS to be found, it is more likely to be found.

In a way the market does work as you describe. If you recall (I'm not sure how publicized it was), the non-subsidized grain farmers of the world were on the brink of bankruptcy around the 2006 timeframe. The solution turned out to be changes to ethanol usage, for better or worse.

It isn't just subsidies, there are also tariffs on the import of sugar to keep the prices high. The market is grossly manipulated by the government and the farming industry.

He does not sound like a paid shill. He's asking perfectly valid questions.

Stop giving out corn welfare to corporations and problem solved. It's the ONLY reason why it's so heavily used. Corn syrup and ethanol - two massively damaging products of a completely corrupt system that everyone refuses to change because of massive profits off taxpayers.

It's not the corn subsidies; it's the tariff on sugar imports. The US cannot produce much cane sugar domestically.

Corn subsidies are only about $2B a year, and 75% of corn is used for animal feed or ethanol.

> The problem is not exactly solved, because it is not clear what the farmers should grow in the place of corn. It's quite possible they should stop being farmers and that the nation should farm out (get it?) much of its agriculture to the developing world. This is certainly what "the market" dictates and something which government spends a lot of money working to prevent.

While it might seem logical in the peaceful times we've grown accustomed to, it is going to still be a tough sell for nations like the USA that have a war-centric mindset. A starving population is how you lose wars, and the work the government does to maintain the local food supply exists for that reason.

Also, there is growing concern for our ability to replenish food-stocks as-is. If farming ceases in these nations, you lose a lot of food people directly eat too.

The problem with the free market and agriculture is that demand is highly inelastic. Therefore the natural price difference between a good year for a crop and a bad year isn't 10%, it is more like 10x, and lots of people get to be hungry from time to time.

However if you can convince farmers to always grow extra, then the difference between a good year and a bad one is closer to 10%, and you never have famines.

After repeated bad experiences, every country with the capability has decided that they want farmers to grow extra in normal years. After that the question becomes how to subsidize them.

I agree completely that corn subsidies are out of control, but it's not clear that getting rid of corn would solve the health problem. It would likely be replaced with 'high fructose' . Fructose has properties (very sweet, doesn't crystallize like sucrose, etc.) that junk food purveyors love and corn doesn't even contain any fructose naturally.

Any starch + amylase makes a syrup (my personal favorite is rice syrup). An extra process turns part of the glucose to fructose making it very sweet.

Sorry to crap on a point I mostly agree with in the name of technical correctness :)

Thanks for the laugh. You know you've reached the pinnacle of "first world problems" when a phrase like corrupt system , which has historically been used to describe things like institutional discrimination and genocide, is now used to describe the "horrors" of agricultural subsidies and tariffs. I'm surprised that Amnesty International hasn't updated their corruption index accordingly, which would surely put every s…

I believe that if one first resolves domestic problems they become more effective in helping people outside the home.

> Thanks for the laugh.

Speaking of which, please don't abuse the other members. It only undermines your humanitarian intentions.
