A cup of coffee in the morning can provide more than just an energy boost.
Health benefits, some researchers say, may extend to helping diabetics reduce the risk of liver disease. Coffee, thought to be consumed more than 400 billion times each year, is one of the most popular drinks in the world.
But is it really healthy or are there risks?
Benefits of coffee
Diseases for which drinking coffee may be beneficial include type 2 diabetes, Parkinson's disease, liver disease, liver cancer and heart disease.
Coffee and diabetes
Coffee may help protect against type 2 diabetes. Researchers at UCLA have determined that drinking coffee increases plasma levels of the protein sexual hormone binding globulin (SHBG).
SHBG inhibits the biological activity of the body's sexual hormones (testosterone and estrogen), which play a role in the development of type 2 diabetes. controls.
One of the authors of the study, Dr. Simin Liu said there was an "inverse relationship" between coffee consumption and the risk of type 2 diabetes. Increasing coffee consumption may reduce the risk of type 2 diabetes.
Researchers at the Harvard School of Public Health (HSPH) collected data from three studies. In these studies, participants' diets were assessed using surveys every four years, and participants self-reported type 2 diabetes by filling out additional surveys.
In total, 7,269 study participants had type 2 diabetes. Researchers found that participants who increased their coffee intake by more than one cup per day for 4 years (an average increase of 1.69 cups per day) had an 11% lower risk of type 2 diabetes over the next 4 years; Compared to people who did not increase their coffee intake.
conducted a study evaluating the link.
The study's authors concluded that "higher coffee and caffeine intake is associated with a lower incidence of Parkinson's disease."
In addition, ka The caffeine in hve may help control movement in people with Parkinson's disease, according to a study at the McGill University Health Center Research Institute (RI MUHC) published in the journal Neurology.
Coffee and liver cancer
Italian researchers found that coffee consumption reduces the risk of liver cancer by about 40%.
In addition, some results suggest that if you drink three cups a day, the risks are higher than 50%.
The lead author of the study is Dr. Mario Negri from the Istituto di Ricerche Farmacologiche in Milan. “Our research confirmed claims that coffee is good for your health and especially your liver,” says Carlo La Vecchia. He concluded.
Coffee and liver diseases
Regular coffee consumption causes primary sclerosing cholangitis, a rare autoimmune disease of the bile ducts in the liver. It reduces the risk of (PSC). Additionally, according to a study conducted at the Kaiser Permanente Medical Care Program in California, USA, coffee consumption may reduce the incidence of liver cirrhosis for alcohol drinkers by 22%. "There is a substance that protects against it." They concluded.
The study, published in the journal Hepatology in April 2014, suggested that drinking coffee helps reduce the risk of death in liver cirrhosis. Researchers have suggested that drinking two or more cups of coffee each day may reduce the risk of death from liver cirrhosis by 66%.
A study published in the journal Hepatology suggests that drinking decaffeinated coffee also lowers liver enzyme levels, suggesting that the benefits are not dependent on caffeine content.
Coffee and heart disease
Beth Israel Deaconess Medical Center (BIDMC) and Harvard Public Researchers at the School of Health concluded that drinking coffee in moderation protects against heart failure.
They defined the need to drink 2 cups of coffee a day. 10 People who drink four cups of coffee a day have an 11% lower risk of heart failure than those who do not.
The authors say so "Coffee provides a possible benefit, but remember that, as with many other things we consume, it really depends on how much coffee you drink," he emphasized.
Other possible benefits
Studies have suggested that coffee can:
-
Help prevent premature deaths.
-
Reduce mortality
-
Protect against cirrhosis
-
Reduce the risk of multiple sclerosis
-
Colorectal protection against cancer
Some of these claims still need to be confirmed by further research.
Nutrition
Regular black coffee (without milk or cream) has a very low calorie count. A typical cup of black coffee contains only 2 calories.
However, if you add sugar and milk, the number of calories may increase.
Antioxidants
Coffee is the number one source of antioxidants in the United States, according to researchers at the University of Scranton. The study's lead author, Ph.D.J. Joe Vinson said that "Americans get more antioxidants from coffee than from other food sources."
The authors of the study point out that one or two cups a day are beneficial, and drink it in moderation.
Caffeinated. and decaffeinated versions provided nearly the same levels of antioxidants.Several studies have linked regular caffeine intake to extra heart beats—a common condition that, in rare cases, can lead to heart problems, stroke, and death.
However, one study found that long-term caffeine intake When looking at consumption, it was found that regular caffeine consumption was not linked to extra heartbeats.
Risks of consuming coffee
Drinking too much coffee can cause very unpleasant negative effects.
According to a study by researchers at the University of Oklahoma, "Caffeine may cause anxiety symptoms in normal individuals, especially in vulnerable patients, as well as those with anxiety disorders."
Also, "Caffeine use, or with symptoms of depression due to the self-medication theory, or a theory that caffeine in itself causes mood changes is also associated."
Women planning to become pregnant should be careful. Researchers from the University of Nevada School of Medicine reported in the British Journal of Pharmacology that regular coffee may reduce a woman's chances of getting pregnant.
Other possible risks include It may disrupt the body clock, having a negative impact on cardiovascular health in young adults with mild hypertension. In one study, researchers detected the presence of mycotoxins in commercial coffee samples, raising concerns about potential public health risks.
