The Coffee Consumption Trends of Men and Women

man-woman-flirting-coffee-shop

Men and women continue to differ in strange ways, and apparently how they drink coffee is one of them.

In Zagat‘s third annual National Coffee Survey, over 1,500 people responded with their personal coffee consumption. The results revealed the following statistics about the coffee habits between men and women.

50.8% of men said they consume coffee, whereas only 32.8% women do.

This stat is a bit mind boggling when you take into consideration how many more women than men one often sees in a coffee shop. It always seems when talking to others that more women drink coffee than men, but perhaps that’s just in the realm of coffee drinkers. We only talk to our own, so perhaps in our world, there are more women than men, percentage-wise. Continue reading

Are you Not Drinking Enough Coffee?

Are you drinking enough coffee?

Are you drinking this many cups a day?

This seems like an impossible question, right? Of COURSE you are drinking enough coffee. It’s your lifeblood. You’re undoubtedly drinking enough.

According to the Dietary Guidelines Advisory Committee, you may not be. The committee is a panel of academics and scientists who advise US agencies on various topics, and these agencies do include the Food and Drug Administration as well as the Department of Agriculture. The committee has determined that drinking coffee is indeed good for you (hooray!), but you should drink 3-5 cups of coffee a day to obtain the full benefits of the beverage. Most Americans, they found, drink only 1.7 cups a day.

The committee has determined that consuming 3-5 cups of coffee per day:

1. Does not have long-term health risks.

In fact, those who say that coffee has long-term health risks have been proved wrong time and time again with current research.

2. Reduces the risk of heart disease.

According to recent research, coffee reduces lower heart and stroke risk factors such as heart rhythm disturbances and arrhythmia.

3. Reduces the risk of type 2 diabetes.

Coffee is a natural diabetes fighter, but if you add sugar to your coffee, you aren’t helping fight diabetes in the slightest.

4. May protect against Parkinson’s disease.

We’ve gone over this before in a previous blog post, so we won’t rehash it here. But if you’re curious how this is possible, visit the link above.

5. Can be incorporated into a healthy dietary pattern.

According to committee member Tom Brenna, “Coffee’s good stuff. I don’t want to get into implying coffee cures cancer—nobody thinks that. But there is no evidence for increased risk, if anything, the other way around.”

In other words, turn your brewer back on and pour yourself another cup of coffee. Chances are, you haven’t had your required dosage today.

Coffee is in Your DNA. Literally.

coffee-bean-dnaHow much coffee do you drink each day? What time of day do you drink it? Did you know that your genes influence how much coffee you consume each day and when your body naturally craves it?

Scientists have known for a long time that your DNA directly influences your jonesing for java, but a new study has identified the genes that dictate your coffee needs.

The study analyzed results of over 20 other studies that analyzed coffee consumption and implemented DNA scans. These studies included over 120,000 participants. This new study looked specifically for any differences in the participants’ DNA that were associated with drinking more or less coffee.

The research team found eight genetic variants, and two of these had already been linked to coffee consumption. Four of the other variants suggest the genes are involved with caffeine, either in how the body breaks it down or how the body responds to the stimulating effects. The other two variants are actually involved with blood sugar and cholesterol.

Surprisingly though, none of the identified gene variants had anything to do with how people react to the taste of coffee. Perhaps they need to run different DNA-scanning study comparing those who drink coffee, those who drink a lot of coffee, and those who do not drink it to isolate that gene.

So the next time someone tells you that you drink too much coffee or maybe you should cut back, you can always say that you’re genetically driven to love coffee this much. Your DNA demands it. Then pour yourself another cup and smile. Broadly.

Which Professionals Drink the Most Coffee?

drink-coffee-and-work-better-3How many pots of coffee does your office chug in a week? In a day? How many of your co-workers constantly have a full mug of joe on their desks throughout the day? Dunkin’ Donuts and Career Builder were rather curious which jobs consumed the most coffee, so they conducted a little survey.

And the top 15 coffee-consuming professions are:

  1. Scientist/Lab Technician
  2. Marketing/PR Professional
  3. Education Administrator
  4. Editor/Writer
  5. Healthcare Administrator
  6. Physician
  7. Food Preparer
  8. Professor
  9. Social Worker
  10. Financial Professional
  11. Personal Caretaker
  12. HR Benefits Coordinator
  13. Nurse
  14. Government Professional
  15. Skilled Tradesperson

That last one is rather vague, to say the least. It’s a little shocking that lawyer did not make the list.

And how do most professionals take their coffee?

Editors, writers, government professionals, and teachers are most likely to add flavor to their coffee.

HR professionals and caretakers are most likely to prefer cream and sugar with their coffee.

Judges, attorneys, and hotel workers most often prefer their coffee to be black.

How much do these professionals need their coffee?

  • 46% of all workers in the US claim they are less productive without coffee.
  • 49% of workers in the Northeast claim they need coffee while on the job, as the ritual for drinking coffee throughout the day in that region is stronger than anywhere else in the US.
  • 61% of professionals who claim they need coffee to get through the day drink at least 2 cups of coffee each and every day.

Where do you and your particular job fall in this survey?

Coffee Could Actually Be GOOD for Your Teeth

coffee-stain-teeth-healthIt’s long been thought that coffee is far from great for your dental health. It’s been attributed to staining teeth and causing bad breath, and while both may be caused by excessive coffee consumption, new research has found that coffee could be good for your teeth.

“We found that coffee consumption did not have an adverse effect on periodontal health, and, instead, may have protective effects against periodontal disease,” said Nathan Ng of the Boston University Henry M. Goldman School of Dental Medicine and lead author of the study.

The study collected data from 1,152 men to participated in the Veteran Affairs’ Dental Longitudinal Study from 1968 to 1998. These participants self-reported on how much coffee they consumed, and the researchers examined them for oral care, hygiene, gum disease risk factors, and even symptoms of diabetes.

What they found was those who were regular coffee drinkers had a decreased risk of developing gum disease. They theorize that the antioxidants naturally present in coffee form a sort of protection barrier over the teeth and gums.

“The results of the study certainly sound encouraging for long-time coffee drinkers who are worried about how their caffeine consumption can affect their dental health,” said Tan Garrett, spokesperson for ErskineDental.net. “When it comes to their teeth, coffee drinking should be the least of their concerns now.”

Of course, the research team wants to expand their study, using a more diverse sample of the population than just veterans. However, this is a great start, and it could be encouraging for those who don’t want to give up their daily cup o’ joe in the name of dental health. But that shouldn’t still sway all ye coffee drinkers from getting your teeth cleaned on a regular basis. That’s still very necessary for your dental health.

Coffee May be Good for Your Eyes

procaffinating_funny_coffee_mug-ree3a558b3445498da5106ccb17de41c5_x7jg9_8byvr_512Ever think that you can see things and read things better after that first cup of coffee in the morning? There may be a reason for that, and it’s not just because you’re finally awake after your first sips of coffee. According to a new study from Cornell University, coffee helps prevent deteriorating eyesight.

The study claims that raw coffee contains roughly 1% caffeine and about 7-9% chlorogenic acid, an antioxidant that prevents the retinas from degenerating in mice.

The retina is a thin layer of tissue that rests on the back wall of your eye. It’s responsible for detecting color and it holds the optic nerve cells that receive and interpret what you see. The retina is one of the most metabolically active tissues in your body, so it is prone to oxidative stress. Continue reading

Coffee May Help with Memory

coffee_with_love

Move over, gingko biloba. Why take an herbal remedy to help you with your memory when that cup of coffee you enjoy every morning does the same thing?

New research from Johns Hopkins University and the University of California in Irvine has found that those who drink at least two cups of coffee (caffeinated, sorry decaf-lovers) may be able to better develop certain types of memories than those who don’t.

They recruited young adults who don’t usually drink much coffee — less than 500 milligrams of caffeine a week, or about five cups of coffee — and who hadn’t had any before the experiment. The volunteers were shown lots of pictures of objects, such as a seahorse, a basket, and a saxophone, and then asked whether each picture depicted an indoor or outdoor item. Soon after looking at the pictures, the volunteers took a pill containing either 200 milligrams of caffeine (which is equivalent to about two cups of coffee) or a placebo.

When the participants returned to the lab the following day, they were given images and asked to label the ones they saw the day before. Some of the images included blatantly obvious additions, but others had extremely subtle differences. Continue reading

Study Suggests Drinking Coffee Alleviates Depression

Happy CoffeeA recent Harvard study has suggested that if you drink two to four cups of coffee a day, it can help alleviate depression.

Their study focused mostly on suicides and risk of suicide. They reviewed three different US health studies that included over 200,000 people and tracked down any death certificates from these studies. From comparing the number of those in these studies who committed suicide with information in the health studies regarding coffee consumption, the researchers concluded that those who consumed 2-4 cups of coffee a day halved their risk of suicide. These cups of coffee were definitely caffeinated coffee, suggesting that half-caff or decaffeinated coffee does not reduce a suicide risk.

Coffee (caffeinated coffee) has been linked to happiness before, but this is the first time it’s been linked with a decreased suicide rate. As such, since most suicides are the result of depression, the study does seem to suggest that coffee can help alleviate depression. (Please note that the study has not concluded or proven this, only suggested it.)

Have you ever noticed that you have a bit of a happy pick-me-up after drinking your first cup of coffee, and it’s not because you’re a little more awake? Have you ever thought that coffee made you a nicer, more pleasant person? Do you look forward to your first cup of coffee of the day, no matter how sleepy or wide awake you are? It turns out there could be something to that. Therefore, it only makes sense that you add another cup of coffee to your daily diet as well as to your orders from MyCoffeeSupply.com.

Research Finds Coffee May Cause Happiness

Coffee Causes HappinessCoffee probably makes you happy simply because you love coffee. Or maybe that’s just why you think coffee makes you happy. According to new research, coffee most likely literally causes happiness.

Lars Kuchinke, a German researcher from Ruhr University, and his team surveyed 66 people for this study. They gave half of them 200mg of caffeine to consume, and then 30 minutes later, asked them to quickly look at a computer screen and determine whether or not they saw any words in a string of letters. The half who had coffee beforehand were 7% more accurate in picking out the positive words from the string than those who consumed a placebo. Continue reading
