12 Health Benefits of Coffee Backed by Science You Can’t Miss

Some myths revolve around coffee and its effect on health.

Some say it's good, while others believe that it's harmful.

But what does the research studies actually show?

We have been checking in depth. Keep reading to know more.

The World Health Organisation (WHO) compiled and reviewed more than 1,000 studies that show coffee can reduce the risk of having liver cancer.

According to the Institute for Scientific Information on Coffee, liver cancer is the fifth most common type of cancer, worldwide.

The raised levels of liver enzymes gamma-glutamyl transferase (GGT) is the cause of damaged liver, which then leads to Liver Cancer.

A research study from Japan suggests that people who drink more cups of coffee have low levels of gamma-glutamyl transferase (GGT), and those who drink alcohol have high levels of GGT.

Dr. La Vecchia explained that this finding might be because of the antioxidants, diterpenes, oils, and caffeine found in coffee.

Liver Cirrhosis, a possible precursor of Liver Cancer, can also be prevented by coffee. Research suggests that coffee drinking is associated with the reduced risk of cirrhosis.

Colon cancer is one of the most common types of cancer in the United States. It affects the Large Intestine, and gastrointestinal problems are the usual signs.

There's a research study, conducted by oncology experts, that suggests that coffee actually has a positive impact on colon cancer patients.

The data showed that the daily consumption of coffee leads to reducing the risk of colon cancer recurrence. Thus, coffee drinkers are more likely to live longer than non-coffee drinkers.

Experts conclude that caffeine reduces the risk of cancer by reducing inflammation. It reduces inflammation by increasing the insulin in the body.

And aside from caffeine, the chlorogenic acid content of coffee, which is an antioxidant, also helped the patients.

Suicide is one of the main causes of death not only in the United States but also worldwide. Countries like North and South Korea, Guyana, Sri Lanka, India, Hungary, and Japan are among the top 20 countries, based on a post from list 25.com.

And according to American Academy of Suicidology, most people who committed suicide also suffered from depression.

Let's see what the studies say about the health benefits of coffee in relation to depression.

In a 10-year study about caffeine and women, they found out that the risk of depression decreases as the intake of caffeine increases.

This study indicated that those with higher consumption of coffee had lower depression risk, compared to those who drank lesser cups of coffee.

A study in Japan suggests that both green tea and coffee can fight depression.

These studies suggest that caffeine helps in blocking the receptors reacting to stress. And lesser stress also meant better mood.

Also, the Harvard School of Public Health noted that caffeine gives a happy feeling similar to the effect of a mild antidepressant.

But still, more studies are needed to back up this finding.

On the lighter side, I know a lot of people who get happier waking up with the smell of a freshly brewed coffee in the morning.

Since caffeine is a stimulant, it affects mainly the brain.

Caffeine helps you stay awake and increases brain activity of dopamine and norepinephrine.

It actually helps your memory, speed reasoning, cognitive function, alertness, and overall brain performance.

Making you smart is the short term health benefit of caffeine. And studies show that it also has long-term effects, it lowers the risk of having Alzheimer's and Parkinson's disease. These are the top two most common neurodegenerative disorders.

7. Caffeine is also Good for the Eyes

Breast Cancer is the most common type of cancer for women worldwide, including Armenia, Denmark, Pakistan, Lebanon, France, Netherlands, and Belgium.

A study from Lund University showed that caffeine may have the ability to slow down or even prevent the growth of cancer cells.

It was said that the caffeine affects the estrogen, which is known to be carcinogenic.

Another study, that lasted for twenty-two years, showed that caffeine may also help in reducing the risk of postmenopausal breast cancer.

After the positive effects of coffee on the skin, let's now note how beneficial caffeine is for the hair.

There's a research study that showed the association of caffeine on hair growth. The study used shampoo with caffeine, unlike with other studies which involve coffee consumption.

A research study  suggests that drinking caffeinated coffee might help in reducing the risk of death of all causes.

This might be the overall impact of coffee's caffeine, antioxidants, and other micronutrients on a person's health.

Despite all these health benefits of coffee, there are also the opposite effects if we had too much of it.
