Lars Kuchinke, a German researcher at Ruhr University, and his team have discovered that coffee is a likely source of happiness. They really didn’t have to spend the money on this research project, I could have told them for free that coffee makes people happy.
The researchers asked 66 people, half of which were given 200 mg of caffeine 30 minutes prior, to quickly look at a computer and determine whether or not they saw any words in the string of letters presented on the screen. The half that were given caffeine, as opposed to those that received a placebo, were 7% more accurate in picking out positive words.
Lars Kuchinke believes that this is because caffeine stimulates the part of the brain that is responsible for positive thoughts. “Although caffeine improves some mental functions, our study shows this may be specific for certain types of stimuli, like only positive words,’ he said.
Caffeine consumption leads to more accuracy and faster response times in simple tasks. It is believed that caffeine increases a brain chemical known as dopamine, which is linked with rewards, creativity, impulsive and addiction.
We love our coffee! That goes without saying, it tastes great, perks us up and makes everyone else bearable on a Monday morning. But the immediate benefits of coffee are not the only reasons to love it.
Kerri-Ann Jennings, M.S., R.D., Associate Nutrition Editor at EatingWell Magazine has given us five health reasons that we should not stop drinking coffee. Here they are:
1. It protects your heart:Moderate coffee drinkers (1 to 3 cups/day) have lower rates of stroke than noncoffee drinkers, an effect linked to coffee’s antioxidants. Coffee has more antioxidants per serving than blueberries, making it the biggest source of antioxidants in American diets. All those antioxidants may help suppress the damaging effect of inflammation on arteries. Immediately after drinking it, coffee raises your blood pressure and heart rate, but over the long term, it actually may lower blood pressure as coffee’s antioxidants activate nitric acid, widening blood vessels.
2. It diverts diabetes: Those antioxidants (chlorogenic acid and quinides, specifically) play another role: boosting your cells’ sensitivity to insulin, which helps regulate blood sugar. In fact, people who drink 4 or more cups of coffee each day may have a lower risk of developing type 2 diabetes, according to some studies. Other studies have shown that caffeine can blunt the insulin-sensitivity boost, so if you do drink several cups a day, try mixing in decaf occasionally.
3. Your liver loves it: OK, so the research here is limited, but it looks like the more coffee people drink, the lower their incidence of cirrhosis and other liver diseases. One analysis of nine studies found that every 2-cup increase in daily coffee intake reduced liver cancer risk by 43 percent. Again, it’s those antioxidants—chlorogenic and caffeic acids—and caffeine that might prevent liver inflammation and inhibit cancer cells.
4. It boosts your brain power: Drinking between 1 and 5 cups a day (admittedly a big range) may help reduce risk of dementia and Alzheimer’s disease, as well as Parkinson’s disease, studies suggest. Those antioxidants may ward off brain cell damage and help the neurotransmitters involved in cognitive function to work better.
5. It helps your headaches: And not just the withdrawal headaches caused by skipping your daily dose of caffeine! Studies show that 200 milligrams of caffeine—about the amount in 16 ounces of brewed coffee—provides relief from headaches, including migraines. Exactly how caffeine relieves headaches isn’t clear. But scientists do know that caffeine boosts the activity of brain cells, causing surrounding blood vessels to constrict. One theory is that this constriction helps to relieve the pressure that causes the pain, says Robert Shapiro, M.D., Ph.D., associate professor of neurology and director of the Headache Clinic at the University of Vermont Medical School.
So go ahead, drink up and live long!
Coffee produces a protein which appears to regulate sex hormones in women, in turn, reducing their risk of developing diabetes, according to a study released by UCLA. The protein has been shown to protect against diabetes.
The study found women who drank four cups of coffee a day were less than half as likely to develop diabetes than those who did not drink any coffee. Decafinated coffee did not appear to produce the same effect on the risk on diabetes.
The Harvard School of Public Health has released an observational study showing that moderate coffee consumption can help reduce the risk of developing certain diseases including diabetes, heart disease, Parkinson’s disease, gallstones, liver cancer and cirrhosis.
The study was based on researchers drawing conclusion based on differences between the number of disease cases in coffee drinkers versus non-drinkers.

infographic which includes Health Benefits, Health Risks, Caffeine Comparisons, and a Facts & Statistics a page addressing each disease the study indicated was affected by coffee consumption.
Unfortunately the Eastern part of the United States is undergoing some major water issues. Flooding is causing a lot of problems, not just with the roads, but with the coffee shop industry due to boil water advisories.
Many people showed up at Dunkin Donuts this morning in the Boston, Massachusetts area only to be met with a smile and an apology. Their coffee orders—-DENIED! The area has experienced a major water main break and are under a boil water advisory until further notice. Coffee is not flowing.
The flooding, home damage and lack of caffeine will surely put a major damper on this week.
You have heard it for years. Personal trainers practice it diligently and so do bodybuilders. It helps your workout making you more effective. What is this miracle substance? Coffee. Plain and simple, coffee has remained a sort of “supplement” of choice among fitness buffs to become fit and maintain fitness.
Coffee is very effective when consumed just before a workout according to research by Dr. Robert Motl of the University of Illinois. It helps to block muscle fatigue symptoms, alowing you to do more and push yourself that extra mile. Its important to remember to also consume enough water during your workout and the rest of your day to counter the fact that coffee is a diuretic.
Go ahead, drink up, workout hard and become fitter with less pain.
Starbucks is testing out alcoholic beverages, just not at its coffee shops. The company is testing out beer and wine along with live music in some stores in Seattle, that are not under the Starbucks brand. They are also hosting book and poetry readings. They are trying to get back to their roots.
Although the company that owns Starbucks will also own these stores, they will not bear the Starbucks name or logo. Just a neighborhood-inspired name that will appear also on bags of Starbucks coffee sold at the stores, though the bags will reportedly contain the same coffee as traditional Starbucks, according to the Seattle Times.
New studies show that caffeine may reduce inflammation in the brain, preventing memory loss.
Dr. Jennifer Ashton, who appeared on the Early Show discussed the findings from studies recently preformed on mice over a period of two months. “Researchers gave the equivalent of 500 milligrams of caffeine per day to little lab mice, who have been induced to have the same kind of memory changes we see in Alzheimer’s disease, and they found a very positive effect on their memory and thinking actions over a two-month period. So put another one in the column of a good effect of caffeine,” she explained.
So how much would a person have to consume to expect the same results? About 5 medium cups of caffeinated coffee a day. “It looks like a lot, but it’s important to realize that now, when we go to a deli or a Starbucks, this could actually be just the equivalent of 2 1/2 large or Grande cups of coffee a day. While it’s a little bit more than most people have in the morning, it’s actually not such an excessive amount,” Ashton said.
So, how does it work? “Their thinking is that actually the caffeine worked by decreasing the inflammation in the brain, cuts down on the buildup of protein we see in the brain of people with Alzheimer’s disease.”
“People are affected by Alzheimer’s. While it’s important to remember that caffeine is a drug, this is something that’s readily accessible in our environment practically. It’s in people’s day-to-day, and something that can have an effect like this is very important and very encouraging.”
Ashton notes that some caution is advised. Caffeine is a drug, and can be associated with increased blood pressure, increased heart rate, jitteriness, palpitations and dehydration.
“For people who have irregular heart beats, hypertension, women who are pregnant or those who are sensitive to the effects of caffeine, coffee, tea or soda should be consumed in moderation.”

Women have fought to get rid of cellulite for years. Now it seems that there is a way to rid yourself of the unsightly stuff. Coffee!!!. That’s right, plain, caffeinated coffee.
Putting coffee on your skin seems to reduce cellulite, or at the very least, the appearance of it. Cosmetic companies have caught on to this and are now using coffee and/or caffiene in some of their anti-cellulite creams. Look for it on the label. Of course, you can also use coffee grounds to get the same effect, but it is much more messy than the creams, which can be expensive.
If you choose to use coffee grounds, its important to do so at least 3 times a week to acheive and maintain the desired results. To do the treatment with coffee grounds, apply warm coffee grounds all over your body and massage it in. Then you wrap yourself in plastic wrap for twenty minutes.
So how does this work?
The caffeine in coffee is the secret. Caffeine helps widen the blood vessel of the body and stimulates the fat cells, breaking them down. Warning though, if you drink huge amounts of coffee daily, your cellulite could look worse. It seems that caffeine when ingested promotes more cellulite formation. Topical application of caffeine does not have this effect.
The rule of thumb when it comes to cellulite? Slather the coffee on and keep it comming for cellulite free thighs.
