High-Fructose Diet Raises Blood Pressure In Middle Age Men

News - Diet Articles

Sept. 23 (Bloomberg) -- A diet high in foods with large amounts of fructose sugar such as sweetened soft drinks increased blood pressure in men, according to a study presented today that also found that a drug for gout blocked the effect.

Men in the study who ate a high-fructose diet had their blood pressure rise about 5 percent after two weeks, while those who also were given a gout treatment increased less than 1 percent, study author Richard Johnson said. Eating great amounts of fructose without the treatment also raised the risk of developing metabolic syndrome, a group of risk factors associated with the development of heart disease and diabetes.


The study is one of the first to show that consuming foods high in fructose raises blood pressure in people, Johnson said. The gout treatment lowered the body’s uric acid that is linked at elevated levels to high blood pressure, diabetes and heart disease.

“Reduce your sugar intake,” Johnson, a professor of medicine at the University of Colorado, Denver in Aurora, said yesterday in a telephone interview. “This data would suggest that too much sugar and high fructose corn syrup may not be a good thing.”

Johnson said larger trials were needed to confirm the findings, particularly before treating people with any drugs including the gout medicine, allopurinol.

‘Exciting Data’

“We’re not ready to lower uric acid as a means to lower blood pressure,” said Johnson, who worked with Santos Perez- Pozo, a kidney specialist and lead author of the research in Minorca, Spain. “It is exciting data that suggests uric acid may have a role in hypertension.”

The study, which was funded by the National Institutes of Health, will be presented today at the American Heart Association’s annual conference on high blood pressure in Chicago.

Fructose is one of several sugars in food and makes up about half of all the sugar molecules in table sugar and in high-fructose corn syrup, according to background information from the American Heart Association. The syrup often is used as a sweetener in packaged food products. Fructose is the only common sugar known to increase uric acid levels, the heart association said.

The study examined 74 adult men in Spain with an average age of 51. The men were given 200 grams (7.05 ounces) a day of fructose in addition to their regular diet. In the U.S., most adults consume about 50 grams to 70 grams of fructose a day.

Blood Pressure

Half of the men in the study were assigned to receive the generic gout drug allopurinol, while the other half were given a placebo. After two weeks, those in the fructose-placebo group had an increase of 6 mm Hg in their systolic blood pressure and a 3-mm Hg rise in their diastolic blood pressure, the researchers found. Systolic refers to the top number in the blood-pressure ratio and shows the pressure when the heart beats, while diastolic is the lower number that measures the pressure between the heart beats.

The men with elevated blood pressure saw their levels return to normal within two months of the study’s end when they went back to their usual diets, the researchers said.

Those getting the high-fructose diet who also were given allopurinol didn’t show significant increases in their systolic or diastolic blood pressures, the study showed.

Metabolic Syndrome

The incidence of metabolic syndrome as defined in the U.S. more than doubled to 44 percent of the group getting the high- fructose intake without allopurinol. The syndrome is defined as having at least three of five risk factors including increased waist circumference, high blood pressure and high fasting-blood sugar. Those in the group receiving allopurinol didn’t experience a rise in metabolic syndrome incidence, possibly because the gout drug stopped their blood pressure from rising, the authors said.

Most sugar consumption in the U.S. comes from sweetened drinks and foods high in sugar or high fructose corn syrup, Johnson said.

The research results suggest it’s possible that lowering uric acid levels could become a routine practice in the future, much like lowering cholesterol.

“This could become a risk factor that is modifiable and that lowering it could be of considerable benefit,” Johnson said. “However we still need more studies to prove it.”

Creatine Supplements...

So, what is creatine? Our bodies naturally make the compound, which is used to supply energy to our muscles. It is produced in the liver, pancreas, and kidneys, and is transported to the body's muscles through the bloodstream. Once it reaches the muscles, it is converted into phosphocreatine (creatine phosphate). This high-powered metabolite is used to regenerate the muscles' ultimate energy source, ATP (adenosine triphosphate).
 
Unlike steroids or drugs, creatine is 100% natural and occurs naturally in many foods; therefore, it can never be banned from any sports or international competitions (unless they banned eating meat). Many foods especially herring, salmon, tuna, and beef contain some creatine. However, the very best source of creatine by far is creatine monohydrate because it contains more creatine per weight of material than any other source. Bodybuilding.com sells only high quality 99.9% pure pharmaceutical-grade creatine monohydrate.

Nitric Oxide Supplements

1. What is it and where does it come from?
Nitric Oxide is a free form gas that is produced in the body and is used by the body to communicate with other cells in the body. To produce this gas, enzymes in the body break down the amino acid Arginine.

Nitric Oxide is a molecule consisting of one atom of nitrogen and one atom of oxygen. The production of Nitric Oxide occurs when the amino acid L-arginine is converted into L-citruline through an enzyme group known as Nitric Oxide Synthase (NOS). The chemical process of conversion is shown in figure 1.

 

Protein Supplements...

High protein diets, like Atkins Diet and South Beach, continue to gain in popularity among many dieters. Some athletes even use these diets and find they lose weight. Depending upon the type of athlete you are and what sort of sport you play, you might want to question the role of the high protein eating plan. Athletes should realize that much of the weight lost on these diets is a result of a decrease in total calories and the water loss that occurs with muscle glycogen depletion. If you perform high intensity or endurance training you probably know that glycogen depletion is one of the reasons athletes 'bonk' or 'hit the wall' in endurance competition. Without enough easy to access energy, in the form of glycogen, we simply run out of fuel.
