Water, according to the U.S. National Institute of Dental Research.
“Pure mist water is better than coffee, and the reason is that it has more flavor and less calories,” said lead researcher Michael Hsu, a professor of food science at the University of Pennsylvania.
“You have less sugar, more nutrients, and less fat than coffee.
That means it’s more energy efficient, more convenient, and it tastes better.”
If you don’t drink a lot of water, Hsu says, you should probably switch to coffee.
“Most people are really not aware that it’s bad to drink water,” he said.
“But you do need to be aware that if you are drinking more than about 20 milliliters a day, you may have a problem.”
To help determine which is better for you, researchers tested water and coffee.
The researchers took samples of the samples and then analyzed them using a liquid chromatography (LC-MS) system, which allows the researchers to determine how much of a sample is coming from the actual water.
The coffee and water were then tested for caffeine, the active ingredient in coffee, as well as a number of other chemicals.
Hsu’s team used two methods to determine which was best for the two beverages.
First, they added caffeine to the coffee water, which gave them the best results.
“We’re using the caffeine in coffee to control the taste,” Hsu said.
He also added sugar and fat to the water, so the water would have less of a caffeine kick.
“Then we added sugar, which makes it taste like coffee.
And we added the caffeine, which made it taste really good.”
The coffee was also tested for alcohol, which is found in coffee and alcohol-free coffee drinks.
“In general, coffee is not alcohol- and sugar-free, and alcohol is really not considered a problem in coffee,” Hsue said.
This is because the amount of caffeine in the water does not change with alcohol content.
But the researchers were not looking for a caffeine-free cup of joe, or a coffee-flavored one, Hsues said.
Instead, they wanted to test coffee and coffee-water as equal parts of a single drink, Hsi said.
Coffee water has more sugar, and so it is less sweet than coffee that has been diluted with coffee.
Coffee drinks contain more sugar than water, and because of that, Hsin added more fat to coffee than water.
“There’s a lot going on in the food chain,” Hsi added.
“The coffee in the cup has a lot more sugar in it than the coffee in a cup you’re drinking.”
The researchers also used a third method to determine the best for a given individual.
They added caffeine and alcohol to the sample, which allowed them to determine what percentage of the caffeine was actually coming from coffee.
They then tested that coffee and its water, looking for the amount that was caffeine-neutral and the amount added sugar.
Coffee-water was the better choice for coffee drinkers, the researchers found.
The study, “A test of the effect of different coffee-based drinks on coffee drinking in healthy adults,” was published in the journal Environmental Science and Technology.
“Our results demonstrate that coffee, when compared to coffee drinks containing sugar, is an effective coffee-drinking beverage,” the researchers wrote.
“However, the results for coffee and other non-coffee beverages are contradictory.”
Hsi says coffee drinkers can get the most benefit from a beverage with more sugar and other nutrients in it.
“If you’re a caffeine addict, coffee and milk are not going to be the best choices,” he added.
Coffee drinking is often a time of relaxation, and caffeine-rich beverages are one way to make you feel more relaxed.
The research team says it plans to continue testing coffee and drinking beverages, and to create new products to help people better balance their intake of sugar and caffeine.
“I hope that our findings can be helpful to people who want to reduce their intake and increase their intake, and also people who may be interested in using coffee as a source of energy,” Hsin said.
The U.K. Food Standards Agency says that coffee contains around 25 grams of sugar per 100 millilitres of water.
A cup of regular coffee contains about 15 grams of caffeine, and a single cup of brewed coffee has between 20 and 60 grams of added sugar each time you drink it.
