A strange effect of Coffee in our Molecular Physiology

By Katherine Lightwood 


My love of Coffee is making me a lot more knowledgeable than I usually am. Yesterday I was drolling over my working table in my institute as I haven't slept much while I was scrolling through the internet. And I found out something really interesting about coffee.

Scientists have again, and again and again tried to find out what coffee is doing to the human body. A study in scientific reports states that coffee consumption has been linked to protective effects on various common pathologies such as cardiovascular disease, hypertension, Alzheimer's, Parkinson's. diabetes, some kind of cancers, hearing functions and it may predispose to others such as sleep disturbances.

Scientist's have been studying coffee since 60's and in 1972 study in  Cell's Biophysical journal tried to find out exactly what it was doing to our cells, noting caffeine binds to broken DNA, and if it's present during the formation of new DNA it can cause breaks in chromosomes. (which is why we've long known pregnant humans shouldn't consume it).

We've also found that when DNA is broken by other processes, caffeine can play with those broken pieces, keeping the DNA broken. But confusingly, a study in March 2016's Molecular nutrition and food research found coffee drinking reduced DNA breakage by a third and the reduction continued for hours. So coffee or caffeine can break DNA or keep it from being broken depending on when the coffee hits your DNA.

It's important to note that DNA breakage is not necessarily a bad thing, normal cell functions can break it, but so can UV light chemicals and certain chemicals and radiation

Another study in the European Journal of Nutrition found that spontaneous DNA strand brakes were somewhat less likely in those who drank dark roast coffee. A study in cell metabolism found the DNA of people who exercised has fewer methyl groups which are special types of chemical markers that occurs when DNA goes through a chemical change. Caffeine mimics that methylation. This shows exercise and coffee affect the DNA pretty dynamically.

And well!! you can change your DNA with your behavior in life which is called epigenetics.
In my opinions lot of these studies have more to do with our love of coffee than then magical powers of this beverage we happen to drink.

So, that was my thought of the day. To see more posts like this make sure to visit our main page. And Do not forget to visit our institute's page to know more about graphic design, 3D, animation courses and other awesome stuff. Till then good day to you.

Mystic Flaming feather  By Katherine Lightwood A famous astrophysicist Carl Sagan once said, “Our universe is a pretty big place. If it’s just us then it seems like an awful waste of space.” This is a human tendency that we focus on ourselves so much, most of the time we tend to forget that there are other things which exist apart from us. It is quite a shame if we compare ourselves with this massive universe. The universe that we see is estimated to be 93 billion light-years across in diameter. Consisting of millions and millions of stars, planets, galaxies and other celestial entities we might never know about. Since the beginning of human civilization, we’ve seen how greed and condescending attitude of mankind has led to the demolition of so many empires through the course of history. We are given this life to be purposeful, not to dwell with each other over those silliest things. We should be responsible for our own actions that are leading to such huge destr

That's how I got into my Christmas Vibe By Nandan Negi  It's one day to go and It's Christmas !! The festival of love, joy, happiness,  and prosperity . This time of the year always makes me so happy because it's winter and a month of festivity and fun . It's quite an exciting time for kids as well. 25th December is believed to be the birthday of Jesus Christ ,  the Savior,  and a Messiah. And the whole world celebrates this day to pay homage to his auspicious birth . Lord Jesus was born to mother Mary,   as it was a divine prophecy by archangel Gabriel. After he was born he did lots of miracles due to which people around him believed that he had something special as normal humans couldn't do that. He has powers like healing people  or producing food out of nothing . It is believed that once he fed his hungry disciples when they had nothing to eat. He just prayed and all the empty baskets were filled with lots of fresh fish, bread and wine.
