What is the difference between filtered and brewed coffee. How do they differ in their effects on the heart?

Filtered coffee tends to be associated with coffee made with a filter bag of some sort.  This is where you put the coffee in the filter itself and the water in a reservoir.  The water is heated and passed through the coffee/filter to create the drink.\n\nBrewed coffee is generally one which is made from an espresso machine.  It doesn't have any filters at all.  Domestic machines are designed so that the water is in a 'container' at the bottom with a funnel type contraption that sits on the top.  This contains the coffee.  Another containers sits on top of that and when the heat is applied the water turns to steam, travels through the funnel and coffee and into the top container.\n\nThe brewed coffee tends to be stronger, so it is more likely to increase your heart rate.

Caffine is a stimulant. Too much can make your heart start to beat too fast, smong other things.

Generally, caffeine will stimulate the Sympathetic Nervous System, thus raising the heart rate

nodoz    you can buy them at wal-mart or a pharmacy...they are caffeine tablets...they can make your heart race, so if you have any heart related illnesses you shouldn't use it. the recommended dosage is equal to 2 cups of coffee.... it is important that you don't overdose or use them all the time\ni used them once and they made me feel like sh*t...i don't recommend them

because the liquid you are stirring is being changed chemically,\nbecause what you are stirring in is becoming 'part of'\nthe liquid in the cup therefor it changes the exerted pressure on the inside of the cup which in kind changes the harmonic resonance of the cup, hence the change in pitch of the clinking. you can test this by stirring your coffee before you add anything and then after/as you add your sugar and/or your creamer

In a 210ml cup:\n\n   Tea, brewed, imported -   60mg\n   Tea, brewed, U.S. - 40mg\n   Tea, instant - 30mg\n   Mate -  25-150mg\n\n"Caffeine content is also affected by the length of the infusion in water. Black tea infused for 5 minutes yields 40-100 milligrams, whereas a 3-minute infusion produces 20-40 milligrams, or half as much. Twenty cups of green tea yield 240 milligrams, or about 12 milligrams per cup.\n\nBecause tea bags contain broken leaves of smaller size, they produce an infusion with more caffeine than loose tea does. This is also true of very fine loose tea."

I am guessing you have some relation with Starbucks and you are buying a lot of coffee. Otherwise, it isn't worth the trouble for a cup of coffee. But you can get a cup of coffee and drop a chemical that would react with caffeine and turn it into a different color than brown. No caffeine no color change. Also no guarantees you can drink it afterwards though.

Want a drug that could lower your risk of diabetes, Parkinson's disease, and colon cancer? That could lift your mood and treat headaches? That could lower your risk of cavities? \n\n\nIf it sounds too good to be true, think again. \n\n\nCoffee, the much maligned but undoubtedly beloved beverage, just made headlines for possibly cutting the risk of the latest disease epidemic, type 2 diabetes. And the real news seems to be that the more you drink, the better. \n\n\nReducing Disease Risk \n\n\nAfter analyzing data on 126,000 people for as long as 18 years, Harvard researchers calculate that compared with not partaking in America's favorite morning drink, downing one to three cups of caffeinated coffee daily can reduce diabetes risk by single digits. But having six cups or more each day slashed men's risk by 54% and women's by 30% over java avoiders. \n\n\nThough the scientists give the customary "more research is needed" before they recommend you do overtime at Starbuck's to specifically prevent diabetes, their findings are very similar to those in a less-publicized Dutch study. And perhaps more importantly, it's the latest of hundreds of studies suggesting that coffee may be something of a health food -- especially in higher amounts. \n\n\nIn recent decades, some 19,000 studies have been done examining coffee's impact on health. And for the most part, their results are as pleasing as a gulp of freshly brewed Breakfast Blend for the 108 million Americans who routinely enjoy this traditionally morning -- and increasingly daylong -- ritual. In practical terms, regular coffee drinkers include the majority of U.S. adults and a growing number of children. \n\n\n"Overall, the research shows that coffee is far more healthful than it is harmful," says Tomas DePaulis, PhD, research scientist at Vanderbilt University's Institute for Coffee Studies, which conducts its own medical research and tracks coffee studies from around the world. "For most people, very little bad comes from drinking it, but a lot of good." \n\n\nConsider this: At least six studies indicate that people who drink coffee on a regular basis are up to 80% less likely to develop Parkinson's, with three showing the more they drink, the lower the risk. Other research shows that compared to not drinking coffee, at least two cups daily can translate to a 25% reduced risk of colon cancer, an 80% drop in liver cirrhosis risk, and nearly half the risk of gallstones. \n\n\nCoffee even offsets some of the damage caused by other vices, some research indicates. "People who smoke and are heavy drinkers have less heart disease and liver damage when they regularly consume large amounts of coffee compared to those who don't," says DePaulis. \n\n\nThere's also some evidence that coffee may help manage asthma and even control attacks when medication is unavailable, stop a headache, boost mood, and even prevent cavities.

"Coffee has more caffeine than tea" --> This is the general misconception among people.\n\nTEA actually holds a higher caffeine content than coffee. Note that the TEA i'm referring here is English tea.\n\nChinese tea and Green tea, however, holds a very small amount of caffeine. These 2 types are consider the most healthy form of tea (with caffeine amount in green tea the lowest)

amphetamines are very dangerous..they are multiple strong doses of caffine like about 50 cups of coffee at once..it raises your heart rate tremendously and can cause heart attack if there is a underlying problem even if you are youn...find a doctor and consult with them

First of all, let me start out by saying that caffeine is found in nature, such as in green tea or guarana. When drunk in smaller quantities such as is found in these herbs, it has an energizing & healthy effect on the body. However, when consumed in larger quantities, the caffeine has an acidifying effect on the body. Any time the body is ill, the acid/alkiline balance has been disrupted. By restoring the alkiline balance, the body is restored to a healthier state & it can heal quicker. Coffee keeps the body in a more acidic state. Caffeine has also been linked to calcium loss. Also, it is associated with decreased bone minerals in women.\nAlso, if you use an automatic drip with the white filters, they use bleach to make the filters white. You're consuming that bleach along with your coffee. Go for the brown or unbleached filters.

there are traces of caffine in decaf coffee.  If you are not a regular coffee drinker, the decaf can stimulate you.  If you begin the regiment of drinking decaf regularly, then you will have to up grade to caffinated eventually.  I suggest not to drink coffee unless you feel you need it.

yes it is, but also if you haven't had tea before and your body wasn't used to it the tea can have a stronger "side effect" too. the Frapp shouldn't effect you too much. I worked at Starbucks and that stuff is mostly sugar. if you had the coffee based ones, its made with espresso powder not coffee coffee.

The short answer is that caffeine increases pulse rate because caffeine increases the strength and frequency of heartbeats.\n\nThere is much more to this but it unfortunately requires a lot of cell biology and biochemistry to fully explain.\n\nHope it helped...TC....HF

Dunce girl almost has it right.  Due to the surface tension of the coffee, there's a compounding effect of greater surface area at the edge of the menicus AND a disproportionately higher concentration gradient.  Hence when the liquid evaporates, since it contains higher concentration of solids, there will be a darker edge.
