A cup of coffee can bring more positive effects than you think.
The US government's increasing limit of coffee to 3 to 5 cups a day in the 2015 nutrition guide has received a lot of support from the people of this country. In fact, coffee has extremely noticeable uses for human health and the following are the most typical effects:

1. Coffee helps you feel energetic and smarter

This is one of the main uses of this drink when it is caffeine - a common stimulant. Specifically, after being consumed, caffeine will flow into the bloodstream to the brain and it will block the transmission of a substance called Adenosine - which is produced when neurons are burned, and the more this substance is reproducing, the nervous system becomes more and more tired. The outstanding ability of caffeine is to disguise the shape and size of Adenosine and enter the receptors without stimulating them.

Therefore, caffeine effectively locks down the receptors, which keeps the brain in a "state of alertness", but excessive use leads to greasy behavior. Many human clinical trials have shown that the brain's ability to absorb caffeine will improve better common functions such as memory storage, emotional control, increased ability to respond to information and improve ability. common sense - in other words, drinking coffee will make you a little smarter.

2. Coffee helps people lose weight

Obesity is a nightmare for anyone and coffee has been scientifically proven to be an effective drink for weight loss, of course, in the right dose. Caffeine in coffee helps fatty acids in the blood to convert into energy easily consumed. Therefore coffee can promote the burning of fat in the body. Caffeine also has diuretic and eliminates toxins from the body.

Research results of the University of Harvard said, every day use from 500 to 600mg of caffeine, equivalent to about 4 cups of coffee will not cause side effects. So, do not exceed the allowed dosage. The caffeine in coffee promotes lipolysis, releasing fat in the blood, so drinking coffee can lead to weight loss. Typically, 4 cups of unsweetened coffee and milk daily can achieve ideal weight loss.

3. Coffee prevents diabetes

In 2014, a study published in the Diabetoligia Specialized Journal found that drinking about 1.5 cups of coffee (about 360 ml) daily for 4 years could reduce the risk of type 2 diabetes by up to 11%. 2. Research experts based three long-term databases that track individuals' lifestyles, diet and physical conditions.

According to research conducted on 7,200 people, those who drink 1.69 cups of coffee / day have reduced the risk of type 2 diabetes, while those who drink less than 1 cup of coffee / day increased. risk of disease up to 17%. Scientists say chlorogenic acid, an antioxidant in coffee, slows intestinal absorption, which is a major reason for limiting and minimizing the risk of type 2 diabetes in people who regularly drinking coffee.

4. Coffee is good for your liver

A 2014 study by the Bethesda Cancer Institute (Marylan, USA) shows that drinking coffee has a positive protective effect on the human liver. Qian Xiao and his colleagues used the survey data to assess the health status of about 27,800 people, aged 20 years old. In the survey, they were physically examined, answered questions about coffee habits and consumption.

The team then analyzed blood samples to examine the liver through four enzymes. High levels of liver enzymes indicate liver damage. Results showed that people who regularly drink from three cups of coffee a day have lower enzyme levels than those who do not have the same habit. In particular, whether drinking regular coffee or decaffeinated coffee, the abnormal enzyme levels in the liver are equally low.

Last year, scientists at the International Cancer Research Foundation discovered that the liver's protective properties from two of the oils found in coffee beans are cafestol and kahweol. The amount of oil depends on how the coffee is brewed, as some methods of brewing coffee can eliminate cafestol and kahweol. For example, brewing from coffee machines that use paper filters to filter the residue, the coffee cup contains only a negligible amount of these two oils, maybe they are absorbed by the paper.

5. Coffee minimizes the risk of various cancers

Indeed, experts from Harvard University (USA) realized that people who drink coffee with moderately low caffeine content can prevent 7 dangerous types of cancer, including breast, prostate cancer. gland, colorectal ... Researchers said that this effect of coffee is due to high levels of antioxidants. Caffeic acid and chlorogenic acid in coffee have antioxidant function, can eliminate free radicals and slow down the aging of the human body, prevent cancer.

People who drink 4 cups of coffee a day are 20% less likely to develop melanoma (skin cancer) than people who drink less coffee. Meanwhile, caffeine has been shown to reverse the risk of prostate cancer in men. Even people who drink coffee regularly can reduce the risk of breast and colon cancer by 50%.

6. Coffee is a method of preventing cardiovascular disease

In March 2015, Korean scientists based on the results of periodic health checks of more than 25,000 workers in Seoul and Suwon cities in the country showed that those who drink moderate amounts of coffee (3- 5 cups a day) is less likely to get early signs of cardiovascular disease.

In this study, experts used the method of scanning the concentration of calcium in the coronary arteries (arteries that supply blood to the heart) to assess arterial calcification as well as cardiovascular health. The results showed that more than 10% of the study participants had calcium spots on the walls of arteries. People who drink just enough daily coffee have fewer calcium spots in the coronary arteries than those who don't drink and drink too much.

7. Drinking coffee will help you live longer

Drinking coffee will help you live longer

This is probably the use that attracts a lot of attention. Scientists at Harvard School of Public Health have conducted three consecutive research programs on more than 200,000 people about the habit of using this interesting drink with a combined frequency of every 4 years and actually For more than a decade now, they have drawn conclusions about the effects of caffeine on people's health and longevity. Survey results vary from people who drink up to 6 cups of coffee a day to some people who do not touch it within 1 month.

The research team published the results of this "long-term" scientific project with the death toll of 12,342 men while 19,524 women also died. Interestingly, most of the dead were among those who "did not touch a single drop of coffee for a month". Meanwhile, those who drink 3 to 5 cups of coffee a day have much lower mortality rates than those who do not drink, especially the proportion of people who die of heart disease, diabetes is relatively low compared to those who did not drink. However, the death rate due to cancer did not differ between the two groups.

In fact, this is not the first time scientists have sought a link between coffee and human longevity. In the last decade, at least 20 similar studies have been carried out and a positive statistic is that coffee has reduced the mortality rate due to most common diseases by 14%. This drink is reasonably priced.

That's enough reason for you to reward yourself a delicious cup of coffee after following this article or not yet ^^?
