Experts have neen trying to establish that coffee plays an important role in our system.This comes in light of the fact that coffee is is one of the constant necceity for most adults.Every so often you would find them holding a white cup in their hands on their way to their work or school.They would often say it helps them wake up and condition their body ifor the working grind ahead.
Some researchers claimed coffee is actually not just a good source of caffeine, which is the primary purpose of many people for drinking it, but it is also a good source of antioxidants.A study revealed a cup of coffee a day could improve a person’s digestive system and lessen a person’s risk of developing heart disease, respiratory problems, cancer, and kidney problems.A new revelation rattled people’s mind when it said that coffee could add years to a person’s life by reducing his risk of developing diseases related to circulation and digestion.
Life Expectancy Improved?
Scientists from America and Europe were involved in the study that suggested the possible boost in a person’s life expectancy by drinking coffee regularly.They examined how the caffeine-filled beverage affects regular drinkers from different walks of life.They came up with results that these people have their life expectancy increased by 12 percent.
These findings were echoed by a study conducted by researchers from the Imperial College London and the International Agency for Research on Cancer (IARC).It said people who drink coffee helps reduce the risk of death among men by 18 percent and women by eight percent.
Naveed Sattar, professor of metabolic medicine at the University of Glasgow, said there are people who drink less coffee because they have an illness.He said, “when some, perhaps many, people are unwell they cut their intake of coffee so that in any given population, many who do not drink coffee or drink less of it may be more unwell.”
However, there are studies that claim the contrary.A study conducted by researchers from the European Prospective Investigation into Cancer (EPIC) looked at the data of 521,330 participants from different European countries.It said around 42,000 participants died from illnesses including cancer, heart diseases, and circulatory diseases 16 years later, while people who are not regular coffee drinkers had a longer life expectancy (increased by about 25 percent for men, 7 percent for women).
There were studies as well that said the effects of drinking coffee would still depend on a person’s lifestyle.They said that unhealthy habits including smoking would have a greater impact on the life expectancy of a person rather than that of how many cups of coffee you drink.
Benefits of Drinking Coffee
One cup of coffee could deliver health benefits as it is filled with antioxidants that could improve the immune system.These include magnesium, manganese, niacin, riboflavin, potassium, and pantothenic acid.These, as well as the other nutrients found in coffee, could also help maintain the health of the circulatory system and minimize a person’s risk of suffering from heart failure.
Apart from these, coffee could also boost brain activity and a person’s energy level.Nutrition researcher Kris Gunnars said, "This is because it contains a stimulant called caffeine." He said after drinking coffee, a person would have caffeine is absorbed into his bloodstream.This chemical would travel to the brain where it will block an inhibitory neurotransmitter called the adenosine.
Gunnars said, “When that happens, the amount of other neurotransmitters like norepinephrine and dopamine actually increases, leading to enhanced firing of neurons.” He noted brain functions that coffee could invigorate include “mood, vigilance, energy levels, reaction times and general cognitive function.”
Coffee can also help burn fat.The caffeine found in coffee can also improve the digestion, and, as a result, enhance the metabolism by eight percent.People who are obese can burn as much as 10 percent, while people who are slim can burn as much as 29 percent.However, it was revealed that some people who drink coffee for a long period of time ended up lessening their fat-burning rate.
Research into coffee benefits revealed as well that people who drink one or two cups per day reduce their risk of developing Parkinson’s disease, skin cancer, liver diseases, and prostate cancer (in men) among other health conditions.It also claimed people may reduce their risk of liver diseases by 80 percent by drinking coffee on a regular basis.In addition, coffee was also revealed to able to help a person deal with depression and reduce their chances of considering committing suicide.
Dr.Veronica Setiawan, lead author of the US study noted though that “We cannot say drinking coffee will prolong your life, but we see an association.If you like to drink coffee, drink up!If you’re not a coffee drinker, then you need to consider if you should start.”
