A cup of coffee can bring more positive effects than you think. The US government's increase in the limit of coffee intake to 3 to 5 cups per day in the 2015 nutrition guide has received much support from the people of this country. In fact, coffee has extremely remarkable uses for human health and below are the most typical effects:
1. Coffee makes you feel more energetic and smarter
This is one of the main uses of this drink when inside it is caffeine – a fairly common stimulant. Specifically, after being absorbed, caffeine will follow the blood vessels to the brain and it will block the transmission of a substance called Adenosine - which is produced when neurons are burned, and more of this substance is released. produced, the nervous system becomes more fatigued. The remarkable ability of caffeine is to mimic the shape and size of Adenosine and enter the receptors without stimulating them.
Therefore, caffeine effectively "locks" the receptors, which keeps the brain in a "awake" state, but too much will lead to addiction. Many clinical trials on humans have shown that the brain that absorbs caffeine improves its usual functions, such as memory storage, emotional control, increased responsiveness to information, and enhanced ability to respond to information. common sense – in other words drinking coffee will make you a little smarter.
Obesity is anyone's nightmare, and coffee has been scientifically proven to be an effective weight loss drink, with the right dose, of course. The caffeine in coffee helps the fatty acids in the blood convert into easily usable energy. Therefore, coffee can promote fat burning in the body. Caffeine also has a diuretic effect and removes toxins from the body.
The results of a Harvard University study show that a daily use of 500 to 600mg of caffeine, equivalent to about 4 cups of coffee, will not cause side effects. So, do not exceed this allowed dose. The caffeine in coffee has the effect of promoting lipolysis, the release of fat in the blood, so drinking coffee can lose weight. Normally, drinking 4 cups of coffee a day without added sugar and milk can achieve ideal weight loss
In 2014, a study published in the journal Diabetoligia found that drinking about 1.5 cups of coffee (about 360 ml) a day for 4 years can reduce the risk of type diabetes by 11%. 2. The researchers relied on three databases of long-term follow-up on individuals' lifestyles, diets and physical conditions.
According to a study conducted on 7,200 people, those who drank 1.69 cups of coffee a day had a reduced risk of type 2 diabetes, while those who drank less than 1 cup of coffee a day increased their risk of developing type 2 diabetes. The risk of getting the disease increased by 17%. Scientists say that chlorogenic acid, an antioxidant in coffee, slows down the absorption of sugar in the intestines, which is the main reason to limit and reduce the risk of type 2 diabetes in people who regularly drinking coffee.
A 2014 study by the Bethesda Cancer Institute (Marylan, USA) showed that drinking coffee has a positive protective effect on the human liver. Expert Qian Xiao and colleagues used survey data to assess the health status of about 27,800 people, aged 20 and older. In the survey, they were given a physical exam and answered questions about their health. habits and coffee consumption.
Then, the team of experts analyzed blood samples to check the liver for four enzymes. High levels of liver enzymes are a sign of liver damage. The results showed that people who usually 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, levels of abnormal enzymes in the liver were equally low.
Last year, scientists from the International Fund for Research on Cancer discovered coffee's liver-protective properties from two of the oils found in coffee beans, cafestol and kahweol. Whether the amount of this oil is more or less depends on how the coffee is prepared, as some brewing methods can remove cafestol and kahweol. For example, brewing from a coffee machine that uses paper filters to filter the residue, the coffee cup contains only a negligible amount of these two oils, which can be absorbed by the paper.
Indeed, a Harvard University expert (USA) found that people who drink coffee with low caffeine content in moderation can prevent 7 dangerous cancers, including breast and prostate cancer. The researchers believe that coffee has this effect thanks to its high content of antioxidants. Caffeic acid and chlorogenic acid in coffee have antioxidant function, can eliminate free radicals and slow down the aging of human body, prevent cancer.
People who drink 4 cups of coffee a day have a 20% lower risk of developing melanoma (skin cancer) than those who drink less coffee. Meanwhile, caffeine has been shown to reverse the risk of prostate cancer in men. Even regular coffee drinkers can reduce their risk of breast and colon cancer by up to 50%.
6. Coffee is a method to prevent 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 this country showed that those who drink moderate amounts of coffee (3- 5 cups a day) are less likely to have early signs of cardiovascular disease.
In this study, experts used a calcium level scan in the coronary arteries (the 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 vessel walls. People who drink the right amount of coffee daily have less calcium spots in the coronary arteries than people who don't drink and drink too much.
This is probably the use that attracts a lot of attention. Scientists from the Harvard School of Public Health have conducted 3 consecutive research programs on more than 200,000 people on the habit of using this interesting drink with a frequency of combined results every 4 years and practice. Over the past decade, they have drawn conclusions about the effects of caffeine on human health and longevity. Survey results ranged from those who drank up to 6 cups of coffee a day to some who didn't touch it for a month.
The research team published the results of this "long-term" scientific work with 12,342 male deaths while 19,524 women also died. Interestingly, most of those who died belonged to the group of people who "had not touched a drop of coffee for a whole month". Meanwhile, people who drink 3 to 5 cups of coffee a day have a much lower mortality rate than those who do not drink, especially the rate of those who die from cardiovascular diseases, diabetes is relatively low compared to non-drinkers. However, there was no difference in cancer mortality between the two groups.
In fact, this isn't the first time scientists have found a link between coffee and a person's ability to live a long life. In the past 1 decade, at least 20 similar studies have been carried out and a pretty good statistic is that coffee reduces the death rate from most common diseases by 14% for users this drink is in moderation.
