Coffee Is A Healthy Food And Health Benefits

Why Coffee Is A Healthy Food And A Health Benefit?

Coffee is a healthy food and a health benefit and a high intake of coffee for coffee consumption and low mortality risk. When people think of coffee, they generally think of their ability to increase energy. However, according to some research, it can also provide some other significant health benefits. And such as a lower risk of liver cancer, type 2 diabetes and heart failure. Worldwide, experts estimate that people consume about 2.25 billion cups of coffee per day.

Researchers have seen the benefits of drinking coffee for conditions such as diabetes, heart disease, inflammatory bowel disease and liver disease. There is evidence to support some, but not all, of these claims. Coffee contains many useful nutrients, including riboflavin (vitamin B-2), niacin (vitamin B-3), magnesium, potassium and various phenolic compounds or antioxidants.

Some experts suggest that these and other ingredients in coffee can benefit the human body in several ways. This article discusses the health benefits of drinking coffee, the evidence supporting those benefits and the risks of drinking coffee.

5 benefits of drinking coffee

Potential health benefits associated with coffee consumption include:

  • Protection against type 2 diabetes, Parkinson’s disease, liver disease and liver cancer.
  • Promotion of a healthy heart.

In the sections below, we cover these benefits in more detail.

1. Coffee And Diabetes

Coffee can help prevent type 2 diabetes and some other conditions.  Coffee can help protect against type 2 diabetes. In 2014, researchers who collected data on more than 48,000 people found and that those who increased their consumption of at least one cup of coffee per day for 4 years had an 11% lower risk of type 2 diabetes than those who consumed it. Did not increase.

A 2017 meta-analysis concluded that people who drink four to six cups of caffeinated or decaffeinated coffee every day have a lower risk of metabolic syndrome, including type 2 diabetes.

2. Coffee and Parkinson’s disease

Several studies have shown that the caffeine present in coffee and many other drinks can help protect against Parkinson’s disease. A team concluded that men who drink more than four cups of coffee per day are at fivefold lower risk than Parkinson’s who do not. In addition, caffeine in coffee can help control movement in people with Parkinson’s, according to a 2012 study.

The results of a 2017 meta-analysis suggested a link between coffee consumption and a lower risk of Parkinson’s disease, even among people who smoke. This team also discovered that people who drink coffee are less likely to experience depression and cognitive conditions such as Alzheimer’s. However, there was insufficient evidence to show that drinking decaffeinated coffee would help prevent Parkinson’s disease.

3. Coffee and liver cancer

Italian researchers found that coffee intake reduced the risk of liver cancer by approximately 40%. Some results suggest that people who drink three cups per day may have a 50% lower risk. In addition, the review of the 2020 literature concludes that “coffee intake possibly reduces the risk of liver cancer.”

4. Coffee and other liver diseases.

A 2017 meta-analysis concluded that consuming any type of coffee seemed to reduce the risk of liver cancer, non-alcoholic fatty liver disease and cirrhosis. People who consume coffee may also have a reduced risk of gallstone disease. In 2014, researchers analyzed coffee consumption among people with persistent sclerosing colitis (PSC) and primary biliary cirrhosis (PBC).

These are autoimmune conditions that affect the bile ducts in the liver. They discovered that people with PSC were more likely to have less unconditional coffee. There was no evidence to suggest that coffee intake differed among people with or without PBC. In addition, a 2014 study suggested a link between coffee consumption and a lower risk of dying from cirrhosis unrelated to hepatitis. The researchers suggested that drinking two or more cups of coffee every day could reduce the risk by up to 66%.

5. Coffee and heart health

A 2012 study concluded that drinking coffee daily or consuming approximately 8 ounces per day can protect against heart failureThose who drank moderate amounts of coffee every day had an 11% lower risk of heart failure than those who did not. A 2017 meta-analysis found that caffeine intake may have minimal benefits for heart health, including blood pressureIn some studies, high levels of blood lipids (fats) and cholesterol were found in people who drink more coffee. Are there benefits or risks for Def Coffee?

Nutritional value

Coffee has fewer calories, but adding sugar and cream will change its nutritional value. Normal black coffee (without milk or cream) is low in caloriesIn fact, a normal cup of black coffee contains only 2 calories. However, adding cream or sugar will increase the caloric value. Coffee beans also contain polyphenol, which is a type of antioxidant.

Antioxidants can help the body eliminate free radicals, a type of waste product that the body produces naturally as a result of certain processes. Free radicals are toxic and can cause inflammation. Scientists have found a relationship between various aspects of inflammation and metabolic syndrome, including type 2 diabetes and obesity.

In 2018, some researchers suggested that coffee’s antioxidant content may provide protection against metabolic syndrome. The author of a 2017 article notes that, although scientists can demonstrate that certain compounds are present in coffee beans, it is not clear what happens to them after entering the human body.

The risk

Drinking too much coffee can also cause some adverse effects. In the following sections, we cover some of these risks.

Bone Fracture

Some studies have found that women who drink too much coffee may have an increased risk of bone fracturesOn the other hand, men who consume more coffee have a slightly lower risk.


The researchers said that coffee intake during pregnancy may not be safe. In fact, there is evidence that suggests a link between high coffee consumption and pregnancy loss, low birth weight and premature delivery.


Women who drink coffee may have an increased risk of endometriosis, but there is insufficient evidence to confirm this link.

Gastroesophageal reflux disease

People who drink too much coffee may have a slightly higher risk of the condition.


Consuming excessive amounts of caffeine may increase the risk of anxiety, especially in people with panic disorder or social anxiety disorder. Less frequently, it can trigger mania and psychosis in susceptible people.

Mental health

A 2016 study concluded that excessive consumption of caffeine during adolescence can lead to permanent changes in the brain. The scientists behind the study expressed concern that this may increase the risk of anxiety-related conditions in adulthood.

Presence of toxins

In 2015, researchers found relatively high levels of mycotoxins in commercial coffee. Mycotoxins are toxins that can contaminate coffee as a natural product. Some people worry that acrylamide, another chemical present in coffee, can be dangerous. Find out more here.


A 2017 meta-analysis concluded that it is “generally safe” that most people consume three to four cups of coffee per day, and doing so could reduce the risk of certain health conditions. However, the study authors caution that smoking can cancel any benefit of drinking coffee. Caffeine is an important characteristic of coffee.

But coffee contains many compounds, and there are different ways to drink it. This makes it difficult to determine how coffee affects a person and what components have benefits and risks. A person who wants to get health benefits from coffee should avoid exceeding the recommended daily intake and try to control those ingredients, such as sugar, cream or flavoring, as they may not be healthy.

Pregnant women and people at risk of fractures can avoid coffee. If you want to buy coffee, there is an excellent selection online.

Coffee is a healthy food: Coffee is popular worldwide and studies generally reported inverse associations (moving in opposite directions) between consumption and the risk of chronic diseases & mortality. But what about people who drink too much coffee and people with genetic variation can affect the way they metabolize caffeine?

“The rigidity of caffeine metabolism varies widely among people,” said Dr. of the Division of Cancer Epidemiology and Genetics at the National Cancer Institute. They said Ericca Loftfield and her colleagues at Northwestern University, Chicago, and the National Cancer Institute.

“Previous data from case-control studies suggested that drinking coffee may increase the risk of hypertension and myocardial infarction. “However, these previous studies evaluated coffee consumption after having the disease and did not examine overall or cardiovascular mortality.”

Dr. Loftfield and his co-authors assessed the coffee consumption habits of 502,641 people using the demographic, lifestyle and genetic data of the UK Biobank. “The UK biobank is a population-based study that invited around 9.2 million people from the UK to participate,” he explained.

We use demographic, lifestyle and genetic reference data as a cohort of biobanks in the United Kingdom, which began in 2006 and ended in 2016, to estimate the risk ratios for coffee consumption and mortality. We investigated the possible modification of the effect by the metabolism of caffeine.

Which is defined by the genetic scores of polymorphisms previously identified in AHR, CYP1A2, CYP2A6 and POR that impact on the metabolism of caffeine. Participants who drank were less likely to die of heart disease and cancer than non-drinkers. Similar findings were observed for participants who drink ground, instant and decaffeinated coffee.

“Together, these findings suggest that the inverse association between coffee and mortality can be attributed to the components without caffeine and to reassure coffee drinkers,” the researchers said. “In addition, research is required to understand the underlying mechanisms of the observed associations.”

The results appear in the JAMA Internal Medicine Journal.
