WASHINGTON: If you are addicted to coffee, and doctors warn you to quit the habit, don't worry, and just keep relishing the beverage, because it's not that bad after all!
Infact, according to a new study, the steaming cup of java even beat fruits and vegetables as the primary source of antioxidants.
The study by University of Scranton states that coffee is the number one source of antioxidants in American diet, and both caffeinated and decaf versions appear to provide similar antioxidant levels.
"Americans get more of their antioxidants from coffee than any other dietary source. Nothing else comes close," said study's lead researcher Dr. Joe Vinson, adding that high antioxidant levels in foods and beverages don't necessarily translate into levels found in the body.
Antioxidants in general have been linked to a number of potential health benefits, including protection against heart disease and cancer, but Vinson said that their benefits ultimately depend on how they are absorbed and utilized in the body.
The researchers analyzed the antioxidant content of more than 100 different food items, including vegetables, fruits, nuts, spices, oils and common beverages. The data was compared to an existing US Department of Agriculture database on the contribution of each type of food item to the average estimated US per capita consumption.
The results were surprising. Coffee came out on top, on the combined basis of both antioxidants per serving size and frequency of consumption. It outranked popular antioxidant sources like, tea, milk, chocolate and cranberries.
Of all the foods and beverages studied, dates actually have the most antioxidants of all based solely on serving size, but since dates are not consumed at anywhere near the level of coffee, the drink comes as the top source of antioxidants, said Vinson.
Besides keeping you alert and awake, coffee has been linked to an increasing number of potential health benefits, including protection against liver and colon cancer, type 2 diabetes, and Parkinson's disease, according to some recently published studies.
The researchers, however, advice that one should consume coffee in moderation, because it can make you jittery and cause stomach pains.
"One to two cups a day appear to be beneficial. If you don't like coffee, consider drinking black tea, which is the second most consumed antioxidant source in the U.S. diet," Vinson said.

Study finds coffee reduces liver risk
Coffee and tea may reduce the risk of serious liver damage in people who drink alcohol too much, are overweight, or have too much iron in the blood, researchers reported on Sunday.
The study of nearly 10,000 people showed that those who drank more than two cups of coffee or tea per day developed chronic liver disease at half the rate of those who drank less than one cup each day.
The study, conducted by the National Institute of Diabetes and Digestive and Kidney Diseases and Social & Scientific Systems, Inc., found that coffee provided no protection to people at risk of liver disease from other causes, such as viral infections.
"While it is too soon to encourage patients to increase their coffee and tea intake, the findings of our study potentially offer people at high-risk for developing chronic liver disease a practical way to decrease that risk," said Dr. Constance Ruhl, who helped lead the study.
"In addition, we hope the findings will offer guidance to researchers who are studying liver disease progression."
Writing in the American Gastroenterological Association journal Gastroenterology, Ruhl and colleagues said caffeine seemed to hold the key.
They analyzed the records of 9,849 participants in a government survey whose coffee and tea intake was evaluated and who were followed for about 19 years.

Caffeine can improve short-term memory

This is your brain. This is your brain on a cafe grande.
For the first time, researchers have been able to watch distinct areas of the brain -- the ones that relate to short-term memory -- fire up after volunteers ingested the equivalent of two cups of coffee.
"Everyone knows coffee makes us more alert, more vigilant, but our study documented how it works in the brain. We were able to show that caffeine modulates a higher brain function through its effects on distinct areas of the brain," said Dr. Florian Koppelstatter, a radiology fellow at the Medical University of Innsbruck in Austria.
Koppelstatter presented the findings Wednesday before the annual meeting of the Radiological Society of North America in Chicago.
Caffeine is the most widely used stimulant in the world, found in coffee, tea, soft drinks and chocolate. Americans, on average, consume 238 milligrams of caffeine (the equivalent of more than 4.5 cups of coffee) each day; worldwide, the per capita consumption is about 76 mg.
Koppelstatter and colleagues used functional magnetic resonance imaging to determine the effect of caffeine consumption on parts of a brain network associated with short-term, or working, memory in a group of 15 healthy male volunteers between the ages of 26 and 47. Some were regular coffee drinkers, others rarely consumed anything caffeinated.
Working memory is the kind of brain activity required to remember things for a short period of time, "like looking up a telephone number in the phone book and storing the number until you've dialed it," Koppelstatter said.
Volunteers abstained from any caffeine for 12 hours before each test. On two separate days, each subject took a capsule that contained either 100 mg of caffeine or a placebo, with researchers switching the dose for each volunteer without letting him know what he was getting.
The men were put inside the MRI scanner shortly before they took the pills while researchers took baseline measurements of their brains. Then, 20 minutes after taking the capsule, they were asked to do a short-term memory task.
"When we subtracted the effects we saw from the placebo studies, there remained significant increases in activity in regions of the frontal part of the brain that control attention and concentration," Koppelstatter said.
He said that while caffeine clearly exerts an effect on normal brain function in the short term, that doesn't mean that the path to superior memory or learning is paved with coffee grounds.
"We still need to learn more about caffeine's effect on mental resources," Koppelstatter said.
