Science tells you why coffee is excellent. Coffee is good.

Besides warming and refreshing, coffee has many benefits. In recent years, scientists have studied coffee's effects on various aspects of health, and the results may surprise you.

Here's why coffee is one of the healthiest drinks on earth.

Coffee can make you smarter.

It's not just refreshing, it makes you smarter. The stimulant in coffee is caffeine, the most common stimulant. Many experiments have shown that caffeine has positive effects on the brain, improving mood, reducing reaction time, improving memory, and improving alertness and cognitive function.

Summary: caffeine blocks neurons in the brain to stimulate them. Experiments have shown that caffeine is good for mood and brain functioning.

Coffee burns fat and improves physical activity

Let me explain why caffeine is the most economical way to burn fat. Caffeine has a stimulating effect on the central nervous system, increasing metabolism and oxidation of fatty acids. Coffee also boosts exercise by several mechanisms, including activating fatty acids from adipose tissue. Two separate meta-analyses showed that caffeine increased physical performance overall by 11 -12%.

Summary: Caffeine boosts metabolism and activates fatty acids from adipose tissue. It also improves physical activity performance.

Coffee May Lower Risk of Type 2 Diabetes

In observational studies, coffee has been found to be effective (23%-67%) in reducing the risk of diabetes. In 18 studies of 457,922 people, a cup of coffee a day reduced the risk by 7%. The more coffee people drink, the less risk they have.

Bottom line: coffee consumption reduces risk of developing type 2 diabetes. People who drink several cups of coffee a day are less likely to develop diabetes.

Coffee May Lower Risk of Alzheimer's and Parkinson's Disease

Not only does it make you smarter in the short term, it protects your brain as you age. Alzheimer's disease is the most common neurodegenerative disease in the world and the leading cause of dementia. Coffee drinkers reduced their risk of Alzheimer's disease by 60 percent in research studies. Parkinson's disease is the second most common neurodegenerative disease in the world, characterized by neural death in the brain. Coffee can reduce the risk of Parkinson's disease by 32% to 60%.

Bottom line: coffee significantly reduces the risk of neurodegenerative diseases alzheimer's and parkinson's.

Coffee is good for the liver.

The liver is the most important organ in the human body, undertaking hundreds of important body functions. In modern life, excessive drinking and sugar consumption can cause certain damage to the liver. Cirrhosis is the final stage of liver damage, caused by alcoholism or hepatitis, until liver tissue is essentially replaced by scarring. Many studies have found that coffee reduces the risk of cirrhosis by 80 percent, especially for people who drink more than four cups of coffee a day. Coffee can also reduce the risk of liver cancer by 40%.

Summary: Coffee has a protective effect on liver disorders, reducing the risk of liver cancer by 40% and cirrhosis by 80%.

Coffee reduces mortality

Many people still think coffee is unhealthy. It is not surprising that truth, when first proposed, is always suspected of being fallacy. In two large prospective epidemiological studies, coffee consumption reduced all-cause mortality. The effect on type 2 diabetes was also dramatic, with studies showing coffee drinkers had a 30 percent lower mortality rate over 20 years.

Summary: coffee has been found to reduce mortality in prospective epidemiological studies, especially in type 2 diabetes.

Coffee is packed with nutrients and antioxidants

Coffee is more than black water. Coffee beans are packed with nutrients, such as vitamins and minerals, that we can drink at the end.

Coffee is also rich in antioxidants. In fact, coffee has the most antioxidants of any Western food, more than vegetables and fruits combined.

Bottom line: coffee is rich in vitamins and minerals and is the most oxidising drink in the modern diet.
