The Good and Bad of Coffee

Is coffee good or bad for human health? The answer depends upon your physical and mental condition and which advantage or disadvantage is of more concern to you. Some people drink coffee as a ‘wake me up’, but there is so much more to this stimulating (pun intended) drink besides caffeine.

The good and bad of coffee has been in debate for years and a highly polarized opinion has been set for this psychoactive drink. People love or they hate coffee. Very few people are out there who are not obsessed with coffee in either way. In the past, people advocate and censure coffee consumption on personal experience and merely made up facts.  

However, in recent few decades, researchers have been trying to find out the good and bad aspects of coffee under the light of scientific studies. In this article, we try to dissect the use of coffee in the same context. It is important to ascertain both the good and bad aspects of coffee drinking, because, as of the latest survey conducted in the beginning of the year, around 44% American consumers stated that they drink two to three cups of coffee per day.

Good Coffee

Let’s find out some of the benefits that can be availed by consuming coffee.

A Catalyst for Weight Loss

According to the scientifically obtained nutritional chart of coffee, coffee is rich in the micronutrients of potassium and magnesium. Ample amount of these minerals in the body regulates blood sugar level by optimizing the function of insulin which also helps in lowering the cravings for starchy and sugary foods. With regulation of insulin and blood glucose levels, there are also reduced chances of developing type 2 diabetes.

Reducing the Risk of Developing Cancerous Tumors

According to a research study that analyzed the effects of coffee consumption on more than 40,000 people, drinking coffee on a regular basis can reduce the risk of developing prostate cancer and endometrial cancer by 20% and 25% respectively.

Another research study indicates that increased caffeine intake in the form of coffee can reduce the danger of developing squamous cell skin cancer.

Beneficial for the Elderly

Keeping the brain’s neuron’s synapses healthy is a major factor in maintaining effective cognitive performance, as well as maintaining the body’s nervous system. There are conditions one can do to help keep the brain’s neuron’s healthy. Some are natural. Some are voluntary, but all have shown signs of success as per numerous scientific reports.

Then there is another neurodegenerative factor that can affect the brain’s health and that is oxidative stress. A study conducted by Harvard University reports that regular consumption of coffee is linked to the reduced chances of developing Parkinson’s disease by lowering oxidative stress and inflammation of the neurons in the brain. A close relative of cognitive neurodegeneration from Parkinson’s is dementia and more specifically, Alzheimer’s disease. 

Some neurons are more vulnerable to oxidative stress than others and these neurons are usually the first to exhibit cell death during the aging process. Analogous to an apple that turns color when exposed to air, the cells in our body can eventually “rust” as we breathe. This is the process of oxidative stress and is caused by free radicals. Free radicals are unstable molecules that damage or “oxidize” cells throughout the body and there are many ways to counter the existence of these precarious molecules, mainly through the use of antioxidants, and coffee has been found to have a high level of antioxidants.

Dr. Barbara Shukitt-Hale, the Lead Scientist in the Laboratory of Neuroscience in Boston has stated: “Coffee is perhaps best known as a source of the stimulant caffeine. However, coffee also contains high levels of polyphenols and consuming phenol-rich foods can have direct effects on the brain and also reduces oxidative stress and inflammation.”Glutathione-3D Illustration

Conclusion: Drinking coffee to lower oxidative stress is a major benefit towards cognitive health.


Bad coffee

Of course, there is a negative side to the consumption of coffee. Let’s take a look at what the effects are. 

It can result in insomnia and restiveness

An excessive amount of coffee can produce the psychological effects that might lead to agitation and sleep deprivation. Some people are inherently sensitive to the psychoactive substance present in coffee, called caffeine.

Pregnancy complications

According to a research paper published in the British Journal of Pharmacology, coffee can induce problems for developing fetus in a pregnant mother. Coffee that reaches the fetus through placenta can have adverse effects on the undeveloped metabolism of the unborn child.

Addictive tendencies

According to a research study published in the Journal of the American Medical Association, people who regularly consume around 350 milligrams of caffeine exhibit the signs and symptoms associated with drugs notorious for substance abuse. For instance, they possess a never-ending desire for coffee and experience the signs of withdrawals when they try to limit its consumption.

Digestive acidity and ulcers

There are various acids present in coffee beans. With excessive regular consumption, they can increase the acidity in the digestive system and can also damage the internal lining of the stomach and small intestine that leads to the ulcer.

People who are suffering from high cholesterol are advised to consume filtered coffee. Filtered coffee is the one with beans that are free of most of the LDL in it.

What path should be taken?

From the above discussion, one can figure out that the goodness or badness of coffee actually boils down to the degree of its consumption. Consuming coffee in moderation is the way forward. If you are drinking more than 1-4 cups in a day then there is a strong probability that you are drinking good coffee. However, if you finish a cup of coffee every hour then it is more likely that you are consuming the bad one.  

Be mindful of your daily consumption, especially if you are pregnant. But looking at the big picture, it is the opinion of this author that the good coffee outweighs the negative potential of bad coffee.

Still not sure, speak to your nutritionist or medical professional who know you and can advise you more thoroughly than any Internat article can do.
