People who consume the amount of fructose found in two-and-a-half regular soft drinks a day appear to have a higher risk of hypertension, a cross-sectional study showed.

"Explain to interested patients that this cross-sectional study could not establish a causal relationship between fructose consumption and hypertension." Keep pushing that SH_T! Rather than 'educating patients'...."There are several possible mechanisms that might explain the positive association between fructose and blood pressure, the authors wrote, "including stimulation of uric acid, inhibition of [the] endothelial nitric oxide synthase system, and stimulation of the sympathetic nervous system, or by directly increasing sodium absorption in the gut." The truth would be more helpful....DOCTORS!

here's a truth. Glucose is broken down into fructose during glycolysis. So we all should be hypertensive if there was a direct link between fructose and hypertension.
So they are right, there must be another process that is causing an increase in hypertension other than the fructose itself.
Lets see if I can take a stab at this, people who consume that many sweetened beverages, probably don't watch what they eat either. People who don't watch what they eat, are more likely to have high sodium diets. The increase in sodium, increases the body's need to create more blood volume to dilute that sodium. That increase leads to increased thirst in an individual, that individual reaches for more sweetened beverages. Creating a cycle.
Because the body can no longer control extra sodium by drinking liquid the hypothalamus increase the blood pressure (aka compensated hypertension) to try to get the kidneys to excrete the excess sodium. Thus, you have high blood pressure.
but ya know, thats just my "guess," lol!

BUZZZZZZIP! your wrong....an opinion, a belief responsible for disease and death.
wrong about what? Is fructose not created in glycolysis? So if everything you eat is broken down into fructose biphosphate in order to create pyruvate for the TCA cycle, then why are we ALL not hypertensive?
That article you linked is stupid. They don't even understand that glucose becomes fructose. They act like its two completely different animals.
Glucose enters the body then is phosphorylated and then isomerized to create fructose. Fructose enters the liver directly and starts at "step 3" instead of "step two".
Lastly the vast majority of your energy production IS done in the liver regardless of what metabolite you start with. Your liver is your buffer for your fats, carbs, and proteins.
So for them to pretend that fructose is special because of the liver, is pretty damn ignorant when it comes to anyone who understand basic biochemistry.

A few years ago I wrote an article about the differences between fructose (natural fruit sugar) and high fructose corn syrup, but lately I’ve realized I didn’t do the subject justice. I was inspired by a commenter on that article who thought fructose wasn’t quite as harmful as I thought. Unfortunately it is and I dug a little deeper for the truth. First I will start out with probably the leading health site, drweil.com, with his June 2002 reply to an “Ask Dr. Weil” question about fructose and High Fructose Corn Syrup:
Yes, there is a difference between fructose and High Fructose Corn Syrup. Fructose is fruit sugar, a simple sugar that makes up one-half of the moleclue of sucrose or table sugar. (The other half is glucose, usually called grape or blood sugar.) Fructose tastes sweeter than sucrose but has fewer calories because the body does not metabolize it well. This has led some people to recommend crystalline fructose as a low-calorie alternative to regular sugar. I do not agree with that recommendation.
The body doesn't handle large amounts of fructose well. You can maintain life with intravenous glucose, but not with intravenous fructose; severe derangement of liver function results. There's also evidence that a high intake of fructose elevates levels of circulating fats, (serum triglycerides), increasing the risk of heart disease. I never use fructose in my home.
High-fructose corn syrup (HFCS) is a recent invention of the food industry, made by an enzyme-mediated process. Old-fashioned corn syrup is less sweet and contains mostly glucose...
HFCS contains 54 percent fructose. Never before in history have so many people been consuming so much fructose, and I am concerned about its possible disruptive effects on metabolism. I'd advise you not to buy products made with HFCS...

I agree with Dr. Weil main points, but I want to clarify some points that I believe that maybe be misinterpreted.
The body doesn't handle large amounts of fructose well.
He is insinuating that the body can handle large amounts of something else well, which isn't the case. The body doesn't handle large amounts of anything well. It doesn't matter if its water, oxygen and yes even glucose.
You can maintain life with intravenous glucose, but not with intravenous fructose; severe derangement of liver function results
That is because the liver is your main buffer. Fructose's (as well as other essential metabolites we won't get into) functional enzymes are located in the liver. It gets over worked if you over load the body with just fructose.
What gets lost in translation here is the fact that IV glucose can be handled up to a point. That is because unlike fructose, other organs can break down glucose to relieve some of the work load off of the liver.
In the hospital, glucose IV must be monitored CAREFULLY, because of the harmful side effects of becoming hyperglycemic. Too much fructose will mess up you liver, but too much glucose will mess up your liver, your central and peripheral nervous system, your muscles, your kidney, your eyes, your blood etc. That stuff deposits everywhere and clogs up functions if it is in excess. If you don't believe me, talk to someone with uncontrolled diabetes. Its not fructose causing their sequelae, its glucose.
I never use fructose in my home.
Then Weil doesn't eat fruits or vegetables, never uses table sugar, honey or syrup, baked goods etc. Fructose is in many foods and it is usually combined with glucose as sucrose.
While its hard to maintain this diet, it isn't impossible. Well follows the same diet that is recommended for a patient with Hereditary fructose intolerance.
http://www.destination-healthy-foods.com/Hereditary-Fructose-Intolerance.html
The problem with giving up fructose ( esp. when you don't need to) is you deprive your body of important antioxidants, vitamins, and cofactors, you probably will have to take supplements to make sure that you are getting adequate nutrition.
Natural fructose from healthy sources are great, HFCS (which is a misnomer because it is fructose (~55%) mixed with glucose (~45%) and laced with crap) is not.

You meant to say that you think doctors seem to think that sugar, HFCS, and artificial sweeteners are a food group.
In reality, doctors understand that sugar is a caloric source that used by your body for energy. Your body takes "food groups" and breaks it down into it its sugar, fat, and protein components.
Sugar is the preferential choice for certain organs such as your brain and muscles, and is the only source your red blood cells can use for energy. That is why complex carbohydrates are strongly recommended (i.e. fruits) because it is a natural source of high quality sugar.
Now, HFCS and artificial sweeteners are highly processed crap who's value is only overstated by the corporate giants that sell it. No doctor who remembers his/her biochemistry supports consuming that mess in high quantities.

HFCS and fructose are two different things. I never said HFCS is a good energy source and the majority of physicians agree that ingesting it constantly wreaks havoc on the system and can lead to obesity and other sequelae.
Fructose and HFCS is not the same thing. Fructose is an intermediate step in energy production. If you avoid fruits and veggies in order trying stay away from it, (either due to a hereditary condition or due to stupidity) your body will override you and make it from the other sources you ingest.

This was my first thought. I'm not a chemist and I really don't know what breaks down into what when it's digested (I'll read up on it - thanks for all the info), but I don't know too many people who eat lots of fruit who have high blood pressure. People who consume lots of HFCS? Completely different story. How fitting that the pic accompanying the article was of soda. But thanks to Big Food, we have to paint all fructose as the same. Ugh. I hope other people see through it.
