Researchers find Red Bull may raise stroke risk

Posted: 8/15/2008 11:25:00 AM |   11 Comments | Post

Australian researchers discovered that Red Bull could be hazardous to your health – in a new way this time.

Just one can of sugar-free Red Bull, according to the researchers, can increase the risk of stroke or heart attack – even in young people – by making the blood sticky, a precursor to cardiovascular problems.

Scott Willoughby, lead researcher from the Cardiovascular Research Center at the Royal Adelaide Hospital, told an Australian Newspaper “One hour after they drank Red Bull, (their blood systems) were no longer normal. They were abnormal like we would expect in a patient with cardiovascular disease.”

Linda Rychter, spokeswoman for Red Bull Australia, said the company’s head office in Austria would assess the report.

"The study does not show effects which would go beyond that of drinking a cup of coffee. Therefore, the reported results were to be expected and lie within the normal physiological range," she told Reuters.

Here's another attempt to discredit the Energy Drink Manufactures. I wonder who sponsored the study and research.

What happens to your blood stream when you consume other products like Alcohol, HFCS, Beer, and Coffee and so on.

It seems that when ever a product leader is doing well, some research scientist, trying to make a name for him/her finds a fault in the product. We consume multiple products daily that aren't good for us. We seem to handle them ok and continue be healthy.

It will be interesting to see what Red Bulls research will turn up.

I also work for them and probably consume more than i should but have never had these symptoms. what about Monster or other 16oz and larger size products? And why just sugar free. I know this e-mag usually dumps on rb, so why not a longer article and not just an exerpt.

It would be nice if they actually figuered out what caused the "stickiness." I'm sure that the ingrediant is in many other produces.

"Just take a close look at Redbull's ingredients....."

Taurine
An amino acid, taurine is important in several metabolic processes of the body. Also known as 2-aminoethanesulfonic acid. Taurine functions in electrically active tissues such as the brain and heart to help stabilize cell membranes. It also has functions in the gallbladder, eyes, and blood vessels and may have some antioxidant and detoxifying properties. 1000 mg

Glucuronolactone
A naturally occurring substance manufactured by the human body. Like taurine, glucuronolactone is supposed to detoxify the body. Little research has been done on the effects, and the only relevant studies have been conducted on animals so the risk to humans cannot be adequately assessed. Glucuronolactone has received some notoriety due to rumours that it was a Vietnam War era drug manufactured by the American government and led to several brain tumour deaths at the time. These rumours are not based on documented facts. 600 mg

Caffeine
An alkaloid found naturally in such foods as coffee beans, tea, kola nuts, Yerba mat, guarana, and (in small amounts) cacao beans. 80 mg

Niacin (niacinamide)
Also known as nicotinic acid or vitamin B3, niacin is a water-soluble vitamin whose derivatives such as NADH play essential roles in energy metabolism in the living cell. Severe lack of niacin causes the deficiency disease pellagra, whereas a mild deficiency slows down the metabolism, which in turn decreases cold tolerance and is a potential contributing factor towards obesity. 18 mg

Pantothenic acid (calcium d-pantothenate)
An antioxidant, water-soluble vitamin needed to break down carbohydrates, proteins, and fats. It is found in whole grain cereals, legumes, eggs, meat and other foods. 6 mg

Vitamin B6 (pyridoxide HCI)
A water-soluble vitamin that exists in three major chemical forms: pyridoxine, pyridoxal, and pyridoxamine. Vitamin B6 performs a wide variety of functions in your body for example, protein and red blood cell metabolism. The nervous and immune systems also require vitamin B6 to function efficiently and it is also needed for the conversion of tryptophan (an amino acid) to niacin (see above). 2 mg

Riboflavin
Also known as vitamin B2, riboflavin is an easily absorbed, water-soluble micronutrient with a key role in maintaining human health. Like the other B vitamins, it supports energy production by aiding in the metabolizing of fats, carbohydrates, and proteins and can be found in milk, cheese, leafy green vegetables, liver, yeast, almonds and mature soybeans. 1.65 mg

Vitamin B12 (cyanocobalamine)
Helps maintain healthy nerve cells and red blood cells, and needed for the production of DNA, the genetic material in all cells. Deficiency of vitamin B12 is the cause of several forms of anaemia. Also called 'cobalamin' because it contains the metal cobalt. 1 mcg

Non-medicinal ingredients:
Carbonated water
Sucrose
Glucose
Citric acid
Inositol
Flavours
Caramel

Nothing life threatening listed...
