Research Round 1: Is coffee healthy or unhealthy?

Hi guys!

So there's a little change to my project plan. I just realized two very important components. The first is that I will on be able to upload 3 rounds before summer vacation, and second that the in depth I was trying to find on each of my four sub topics are combined. So the new plan is that my first round will be about advantages, second round about disadvantages, and the third round about the addiction side of coffee and caffeine. 

                                                               ***

For my first round of research I will be looking into ther quite broad topic of any advantages to drinking coffee. I'll try not to get all you coffee drinker's hopes up because sadly there will be disadvantages to follow in the next round.

Energy: 

Obviously there is a quite well known advantage of gaining energy, but what i bet you didn't know is that how caffeine affects you is actually dependant on genetics. I too just learned this recently and decided to dig a little deeper. Some of you have probably hear of a DNA test called 23andme. For those of you who haven't heard of this test all you do is pay a fee and you're sent a little kit, which includes a tube and a few other things. You're supposed to spit in the tube and create an online account. after that you're supposed to send the tube back to lab and wait for any results. These results for my mom included where she's from, her hair colour, other appearance factors, and behaviour ones (some are strange like whether or not her pee will smell after eating asparagus). Low and behold one of the traits was if caffeine made her more or less energetic. 

 

People who metabolize slow feel longer and stronger affects of caffeine because their body takes the time to process the "fuel" it was given, meanwhile people who metabolize quickly don't feel quiet the same effect. That's pretty cool if you ask me. (1) 

Academic:

I first started drinking coffee when I was got to high school. I had read an article about how to preform better on tests, one of the suggestions was to drink a coffee before. It was meant to stimulate your brain and get all those good brain juices flowing. 

This article made sense because when you have a cup of coffee the caffeine is absorbed into your bloodstream and will eventually travel up and through your brain. (3)

Weight Loss: 

Caffeine can be found in almost every dietary supplement that helps to burn fat. according to some studies caffeine can boost your metabolism by anywhere from 3-11%. (4) And others say that it can increase the time of burning fat by 10%. (5)

Physical Performance: 

Caffeine creates more adrenaline in your body and blood. (6) Adrenaline controls the fight or flight reciprocals in our brains so you can argue that having more of chemical can be beneficial for our overall well being. 

Nutrients: 

One cup of coffee contains vitamin B2, vitamin B5, manganese, potassium, magnesium, and niacin. (7) These are a fairly important group of nutrients that benefit us. 

Lower Risk of Type 2 Diabetes: 

A study showed that people who drank the most coffee lowered their risk of developing type 2 diabetes by 23-50%! (8) And according tot a massive review of 18 studies came to the conclusion that every daily cup of coffee can reduce the risk of developing diabetes by 7%. (9)

Coffee may be able to protect people from developing alzheimer's or dementia:

Alzheimer's and Dementia are two very similar diseases that affect (mainly) memory of people over the ages of 65. Unfortunately there is no known cure for Alzheimer's. There are steps that can be taken to avoid developing the disease in the first place, which include exercising and eating healthy, but apparently drinking coffee can be just as effective.  There are studies that have shown that coffee drinkers risk of developing Alzheimer's is 65% lower than non coffee drinkers. (10)(11)

Helps Fight Depression: 

This kind of relates to my last research topic about mental illnesses. There was a harvard study done in 2011 and the results came back that women who drank 4 cups of coffee a day or more had a 20% lower chance of developing depression. (12) There was also another study done where they took a large group of women and came to the conclusion of those who drank four or more cups a day were 53% less likely to commit suicide. (13)

Lengthen Life: 

Studies were done where it showed that drinking coffee was associated with a 20% lower risk of death in men and 26% in women, over a period of 18-24 years. (14)

There are many more benefits around drinking coffee, including a lower risk of some cancers. Coming into this research I was not expecting to find this many benefits to drinking coffee.

Original Post

Hey Alanna,

I love your topic this round. Having heard both sides ("never drink coffee it will stunt your growth!" vs "coffee has so many benefits, I'm addicted"), I think it would be great to see if you can find the true conclusion to the debate.

Related back to the part about stunting growth and the like, I think it would be neat if you compare the effects of coffee on adolescents/children and adults. Is it actually worse for a child to drink a cup of coffee?

Good luck, I look forward to reading your work!

Hi Alanna,

Wow! I did not know that there were so many benefits to drinking coffee. To be honest this makes me feel a bit better. That is an incredible amount of pros which all seem quite unbelievable. Your post was packed with info and was really a pleasure to read. You had lots of references and everything was organised.

Looking forward to reading more, hopefully there aren't to many cons  

Hi Alanna,

This is a very good topic when coffee becomes a kind of habit, not many people would pay attention if they really help our health. It's interesting to know how caffeine is absorbed and worked in our body and the knowledge you gave our is very convincing. What's more, you listed out many reliable resources which are appreciated.

Looking forward to your next post! Have a good luck!

 Hi Alanna! 

 I found this research round very interesting. I knew that caffeine was an energy booster, but other than that, I had only ever heard about the negative effects of coffee. People always say "Oh, it's so addictive" and "It's not good for you" so I never knew there were actually positive things about it. I was really surprised to learn about it affecting life span, risk of depression, and academic performance in a positive way! 

 For your next round, if you're looking at the disadvantages of drinking coffee, one thing I would suggest is looking at how much money people spend on coffee. It seems to be quite a problem in today's society. 

 Good luck!
