A sweet problem: Princeton researchers find that high-fructose corn syrup prompts considerably more weight gain

by Hilary Parker, March 22, 2010, http://www.princeton.edu/main/news/archive/S26/91/22K07/

A Princeton University research team has demonstrated that all sweeteners are not equal when it comes to weight gain: Rats with access to high-fructose corn syrup gained significantly more weight than those with access to table sugar, even when their overall caloric intake was the same.

In addition to causing significant weight gain in lab animals, long-term consumption of high-fructose corn syrup also led to abnormal increases in body fat, especially in the abdomen, and a rise in circulating blood fats called triglycerides. The researchers say the work sheds light on the factors contributing to obesity trends in the United States.

"Some people have claimed that high-fructose corn syrup is no different than other sweeteners when it comes to weight gain and obesity, but our results make it clear that this just isn't true, at least under the conditions of our tests," said psychology professor Bart Hoebel, who specializes in the neuroscience of appetite, weight and sugar addiction. "When rats are drinking high-fructose corn syrup at levels well below those in soda pop, they're becoming obese -- every single one, across the board. Even when rats are fed a high-fat diet, you don't see this; they don't all gain extra weight." http://www.princeton.edu/main/news/archive/S26/91/22K07/

Richard Johnson, MD, also reported in the same peer reviewed journals that the metabolism of fructose in our cells uses up ATP,

Wikipedia: … Metabolic processes that use ATP as an energy source convert it back into its precursors. ATP is therefore continuously recycled in organisms: the human body, which on average contains 250 grams (8.8 oz) of ATP[3] turns over its own weight in ATP each day.[4] …

The structure of this molecule consists of a purine base (adenine) attached to the 1' carbon atom of a pentose sugar (ribose). ... When ATP is used in DNA synthesis, the ribose sugar is first converted to deoxyribose by ribonucleotide reductase. … http://en.wikipedia.org/wiki/Adenosine_triphosphate

which turns into purine on cell death and the purine is converted to Uric Acid. Recent publications has proved that uric acid inflames the blood vessels which prevents expansion of the blood vessel so blood pressure increases to get enough blood through the vessels. The higher blood pressure in kidneys increases even more much so that kidneys function goes down. It was reported a few weeks ago in the online Nephrology publication. Also when kidney patients are treated to reduce uric acid, kidney deterioration slows down considerably.

Study: High-Fructose Diets May Raise Blood Pressure

Added Sugar May Be Linked to Hypertension Risk

July 1, 2010 -- Foods and beverages with high amounts of fructose from added sugar may increase your risk of developing high blood pressure, according to a new study in the Journal of the American Society of Nephrology. High blood pressure is a major risk factor for heart attack and stroke.

A type of sugar, fructose is a key ingredient in table sugar and high-fructose corn syrup. Added sugars are found in processed foods such as candy, cookies, and cakes, as well as soda.

For the study, data on 4,528 U.S. adults were collected from the National Health and Nutrition Examination Survey in 2003-2006. Fructose intake was calculated based on self-reported diet information. Those participants who reported eating or drinking 74 grams of fructose or more per day (which the study equates to 2.5 sugary soft drinks per day) had a higher risk of high blood pressure than their counterparts who got less fructose. The findings took into account factors such as age, smoking history, physical activity level, and salt and alcohol intake.

However, the study doesn’t prove that fructose was the cause for the rise in risk.

A link between added sugars and blood pressure is controversial. There are several theories about how fructose affects blood pressure levels, but none is firmly established. For example, high-fructose corn syrup may raise uric acid levels, which have been linked to high blood pressure.

“Limiting fructose intake is readily feasible, and in light of our results, prospective studies are needed to assess whether decreased intake of fructose from added sugars will reduce the incidence of hypertension and the burden of cardiovascular disease in the U.S. adult population,” conclude researchers who were led by Diana I. Jalal, MD, of the University of Colorado Denver Health Sciences Center in Denver.

Study Flawed, Critics Say

Not so fast, according to The Corn Refiners Association, a national trade group based in Washington, D.C., and others.

The Corn Refiners Association takes issues with the findings and the methodology used in the new study. “The authors failed to learn the true composition of sweeteners used in caloric soft drinks,” according to a statement released by the group. “Caloric soft drinks are not sweetened with 100% fructose. The sweeteners they contain are comprised of almost equal portions of the two simple sugars fructose and glucose, because they are sweetened with either sucrose (table sugar) or high fructose corn syrup (corn sugar).” … http://www.webmd.com/hypertension-high-blood-pressure/news/20100701/study-high-fructose-diets-may-raise-blood-pressure

HFCS Making Us Fat and Sick

USA Sugar 10.6% of All Calories 1977-1978 and 1999-2006 15.8% (21.4 Teaspoons, 359 calories) Reagan's Fault?

This journal article was probably submitted before the Princeton study showing that equal calories of HFCS High Fructose Corn Syrup which is 55% Fructose and 45% glucose and cane sugar 50:50 fructose and glucose. Why did this apparently small change make such a difference in our health?

Reagan wanted to greatly increase the profits of large corporations involved in food production so the farmers got subsidies greater than the cost of producing, but so much corn was produced to keep prices low so the farmers had to produce lots of corn to get enough to feed their families! So the large corporations were able to sell corn worldwide and put local farmers out of business.

Cane sugar could not be added to fiberless foods in high amounts because it tended to crystallize out on freezing or standing. Liquid High Fructose Corn Syrup which is sweeter than glucose and sucrose, could be added in any amount to prepared foods without crystallizing. So they did not have to worry about making the taste good from tasteless corn and soybean, but just added HFCS.

Fructose does not convert to glucose in our blood and has to be processed by our liver. There part of it is converted to glucose which is stored as glycogen to be used as needed for energy, but 30 percent are converted to low density lipoproteins or the bad heavy LDL-2 which leads to plaques in our arteries.

Fructose also increases our triglycerides which leads to heart disease. If this was not enough, it also produces uric acid which acidifies our blood and gives us gout and high blood pressure independent of salt. Note salt does increase our blood pressure when used in excess, but salt also works by another mechanism to thicken our heart which leads to congestive heart disease.

We are the only ones that can change this. Complain to our political leaders, to newspapers, and to the food producers themselves. Already Coke and Pepsi have removed their colas from the school vending machines which Oregon did first and greatly improved the health of the students at a young impressionable age. Jaime a chef on ABC on Friday at 9:00 PM is trying to change the food habits of Americans starting with the most obese town in the USA, Huntington, West Virginia. Almost everyone has family members who died from diseases due to obesity.

With our government health department calling french fries vegetables, you can imagine how difficult it is. I will check him out on Friday and record Bill Moyers whose programs have been outstanding on PBS.

ScienceDaily (Apr. 22, 2010) — Consuming a higher amount of added sugars in processed or prepared foods is associated with lower levels of high-density lipoprotein cholesterol (HDL-C, the "good cholesterol") and higher levels of triglycerides, which are important risk factors for cardiovascular disease, according to a study in the April 21 issue of JAMA.

Jean A. Welsh, M.P.H., R.N., of Emory University, Atlanta, and colleagues assessed the association between consumption of added sugars and blood lipid levels in U.S. adults. The study included 6,113 adults from the National Health and Nutrition Examination Survey (NHANES) 1999-2006. Respondents were grouped by intake of added sugars using limits specified in dietary recommendations (less than 5 percent of total calories [reference group], 5 percent to less than 10 percent, 10 percent to less than 17.5 percent, 17.5 percent to less than 25 percent, and 25 percent or more of total calories).

"In the United States, total consumption of sugar has increased substantially in recent decades, largely owing to an increased intake of 'added sugars,' defined as caloric sweeteners used by the food industry and consumers as ingredients in processed or prepared foods to increase the desirability of these foods," the authors write. No known studies have examined the association between the consumption of added sugars and lipid measures, such as HDL-C, triglycerides and low-density lipoprotein cholesterol (LDL-C).

Various measures calculated in the study included average HDL-C, average triglycerides, and average LDL-C levels and adjusted odds ratios of dyslipidemia (abnormal amounts of lipids and lipoproteins in the blood), including low HDL-C levels (less than 40 mg/dL for men; less than 50 mg/dL for women), high triglyceride levels (150 mg/dL or greater), high LDL-C levels (130 mg/dL or greater), or high ratio of triglycerides to HDL-C (greater than 3.8). Results were weighted to be representative of the U.S. population. ... http://www.sciencedaily.com/releases/2010/04/100420161748.htm
