Ways to Balance: Caffeine, the Angel and the Devil

  • 7

Caffeinated beverages are everywhere. You may not be able to work without a coffee in the morning or after the lunch break, or you need to consume your favorite beverages all day long to keep you concentrated and energetic.



You may have heard that too much caffeine isn’t good for your health, and some people ARE suffering from caffeine use disorder, a condition where your body is unable to reduce caffeine consumption even you already have other conditions that may be impacted by caffeine.


However, caffeine also does us good in many ways. It can help us concentrate, be active, and fight obesity. Research is revealing other effectiveness on what a proper amount of caffeine can help with multiple diseases, including heart, kidney and mental-related diseases.


This post will help you know some daily effects of coffee in our life.



Preventing skin cancer cause by sun exposure when exercising


Isn’t it surprising, that caffeine should have some relationship with skin cancer? Research showed the combined effects of exercise plus caffeine consumption may lower the risk of skin cancer and inflammation related to other obesity-linked cancers.


Science behind


The researchers applied the combination of caffeine and exercise to mouse model, and found that the combination treatment can decrease sunlight-caused skin cancer formation.


A dose of caffeine and exercised with a running wheel on mice showed 62% fewer skin tumors and 85% shrink in the volume of tumors, compared with the mice that did not consume caffeine or exercise.


The results also showed that the tumor can be reduced by 27% with only caffeine or exercise alone.


Researchers believe that the findings can be extrapolated to humans for our benefits as well.



Coffee helps fight against obesity


You may have heard that black coffee can help lose weight. This is mainly about the fat-fighting defenses in our body called “brown fat”.


Science behind


“Brown fat” is actually called brown adipose tissue (BAT), one of two types of fat found in mammals including, of course, humans. Brown fat can generate body heat by burning calories, while white fat is a result of storing excess calories.


Previously people thought only babies and hibernating mammals have brown fat, but recent study showed that adults can have brown fat too. You can more likely find brown fat in people with a lower body mass index (BMI).


Researchers found that something like a cup of coffee can have a direct effect on our brown fat functions, which can be used to reduce obesity, a major health concern and a cause of many medical conditions.



Caffeine makes you anxious


A new post by Pennsylvania State University recently published to reveal the relationship between anxiety and caffeine consumption.


“Caffeine is not the enemy, but I encourage people to know healthy limits and consume it strategically because it is activating and can mimic or exacerbate the symptoms of anxiety.” Said Dr. Julie Radico, a clinical psychologist with Penn State Health.


Caffeine can cause problems for those with general anxiety disorder. Consuming a large amount of caffeine (over 400mg) in a short time can lead to other side effects including racing heart, nausea or abdominal pain.


Although the amount of recommended caffeine consumption varies from person to person, the general recommendation is based on body weight.



Caffeine use disorder: a widespread health problem


Caffeine doesn’t only exist in coffee. You can also find it in soda, tea, chocolate, and energy beverages. You are consuming more caffeine than you could realize every day.


In the article “Caffeine Use Disorder: A Comprehensive Review and Research Agenda” coauthored by professors from American University, Johns Hopkins University and the University of Vermont, the physical and psychological symptoms experienced by habitual caffeine users in previous studies were reviewed.


The American Psychiatric Association has officially recognized Caffeine Use Disorder as a health concern.


Considering how widespread the dependence of caffeine is, one of the coauthor claimed that labeling caffeine amount on the products containing caffeine may help people control their caffeine consumption.

Recommended amounts of caffeine consumption


The recommended caffeine consumption for Americans is 400 mg/day or less for healthy adults with no conditions associated with caffeine intake. Pregnant women are recommended to intake 300 mg/day or less, and the consumption for children is recommended to be 2.5mg/kg-day or less.


Here are the amounts of caffeine in common beverages and foods. 8 oz. is about a cup of the drink. A standard Coca Cola is 12 oz.

Wow, I feel heart beat strangely after a cup of coffee or black tea, but am perfectly ok after drinking green tea and oolong tea, now I see why. Apparently 40 mg caffeine is the limit of my poor heart. Thank you, author.
A bottle of 5-hour energy regular contains 200 mg caffeine, equal to two cups of espresso, so strong. No doubt it makes you so awake.
How long does caffeine last? Would it be OK if I just drank a cup of coffee in the morning? I LOVE coffee and I DON'T want to give it up... Please advise. Thx.
It's recommended not to drink coffee in the late afternoon and evening. So you'll be fine. :)
Y'all are dumb:)
Yeah, they are
Why are they dumb??
That are white people
My mother was a brown person,(American Native Ho Chunk and Ojibway), so does that make me only half dumb?  She was extremely intelligent and self-taught, as was my 100% Norwegian, first generation,  father. Both were avid readers. They had to drop out of high school because of the depression. Later my mother got her GED and became an LPN in her 40s. My father was always taking classes. He got his pilots license and  was instrument rated. That took many many hours of practice, on a LINK trainer and flying “under the hood”,   with an instrument rated flight instructor. Basically,  that means you are flying blind and can only see your instruments, as would be the case in severe weather. He got both his real estate agent and brokers licenses. At a community college he learned  small engine repair  so he could maintain his boat, pontoon boat, motorcycles and snowmobiles. I have such fond memories of fishing from the boat and icefishing on the frozen lakes “up north” in Wisconsin with my father. We always had a stainless steel thermos of good strong Norwegian coffee! I learned how to fly before I had my drivers license. On Saturday mornings,  Dad and I would drive out to the airport so I could take my flying lesson.  Not only did I get in some driving and flying practice, but I got to spend quality time with my brilliant and wonderful father. Naturally, we had Dad’s sturdy Stanley thermos filled with more strong Norwegian coffee.After my lesson, I would meet Dad in one of the hangers to do some “hanger flying” with the other pilots.  He would always meet me with the thermos cup  filled with hot coffee.  Even though I was a skinny 16-year-old girl, I was welcomed into the circle of “hanger pilots”.  There is no way I am ever giving up my coffee! I have too many memories that hover over each cup of aromatic brew.    Every time I forced myself to drink a cup of the battery acid in the huge percolators at every Navy facility, I would imagine it was delicious coffee I was having with my father while fishing or after a flying lesson. if anyone is wondering why I forced myself to drink that disgusting swill, it was out of necessity. I was working brutally long hours as a Hospital Corpsman/ medic, on the island of Guam. After South Vietnam fell to communism,  we were caring for thousands of displaced South Vietnamese.

 Caffeine, albeit in the form of nasty Navy coffee, helped one young woman put one foot in front of the other, day after day, for many months.
But the looks of the statement they are dumb cause they are white people. That shows whose really dumb.
No one is dumb because of their race or color. Why cant we be better and stop ignorant statements like that. Let's try to change how people think. Not encourage racism. it's really disappointing. I'm not white but I dont think anyone is dumb cause they are white.     LETS STOP THE HATE.
I couldn’t figure out why they were saying we were “a bunch of dumb white people” to this  question, without offering any intelligent comment.I was just posing the answer that if I am half brown and half white am my only half dumb? It was a facetious question.  I think it was just some kids being stupid. Overall, I have met so many wonderful people online. I have been housebound the last five years due to pancreatic cancer. I had a 10 hour Whipple surgery, chemo and radiation. Side effects of all of that have kept me pretty much at home or at the VA hospital. My Whipple Warrior support group and various other Facebook groups for artists, writers, advocates for various causes have kept my mind active. If my body can’t be active, at least my mind can be.
Where did this rage come from? The post is talking about coffee, Jesus!
Thank you for your service. I pray you get well soon.
I'm with you.
You're an idiot!  Racist...
love dark chocolate!
Great idea to put caffeine amounts on products!!
Coffee drinkers can halve their risk of liver cancer, according to Queen's University. The type of cancer they studied is hepatocellular carcinoma (HCC), the most common type of liver cancer.  The researchers found that coffee drinkers were 50% less likely to develop HCC compared to those who did not drink coffee. But they didn't find any consistent links in stomach or bowel cancer with coffee drinking.
