Everyone recognizes a roasted coffee bean, but you might not recognize an actual coffee plant.
Coffee trees are pruned short to conserve their energy and aid in harvesting, but can grow to more than 30 feet (9 meters) high. Each tree is covered with green, waxy leaves growing opposite each other in pairs.
Coffee cherries grow along the branches. Because it grows in a continuous cycle, it’s not unusual to see flowers, green fruit and ripe fruit simultaneously on a single tree.
It takes nearly a year for a cherry to mature after first flowering, and about 5 years of growth to reach full fruit production. While coffee plants can live up to 100 years, they are generally the most productive between the ages of 7 and 20.
Proper care can maintain and even increase their output over the years, depending on the variety. The average coffee tree produces 10 pounds of coffee cherry per year, or 2 pounds of green beans.
All commercially grown coffee is from a region of the world called the Coffee Belt. The trees grow best in rich soil, with mild temperatures, frequent rain and shaded sun.
Reduce tired and increase energy levels
Because it contains a stimulate called caffeine. It is absorbed into the bloodstream, then transferred to the brain to block an inhibitory neurotransmitter called (adenosine).
When this happens, the activity of other neurotransmitters such as Norepinephrine and dopamine increases, which fire the activity of neurons.https://www.ncbi.nlm.nih.gov/pubmed/8232842 https://link.springer.com/article/10.1007/s002130000383 https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1600-0773.1995.tb00111.xhttps://www.ncbi.nlm.nih.gov/pubmed/1356551 https://www.sciencedirect.com/science/article/abs/pii/0024320582907159
Several studies proved that caffeine can boost your metabolic rate by 3-11%.
Other studies indicate that caffeine can increase fat burning by up to 10% in particularly obese people, and 29% in slim people. However, these effects can diminish in people who drink coffee in the long run. https://www.ncbi.nlm.nih.gov/pubmed/2912010 https://www.ncbi.nlm.nih.gov/pubmed/14684395
Improve physical performance by 11-12%
Caffeine stimulates the nervous system, sending signals to the fat cells to break down body fat into the basic units (fatty acids) that become available as fuel for the body.
It also increases levels of adrenaline in the blood (fight or flight hormone), which prepares the body for intense physical exertion.https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1600-0838.2005.00445.x https://www.ncbi.nlm.nih.gov/pubmed/7408399 https://www.ncbi.nlm.nih.gov/pubmed/8201901

It may reduce your risk of developing type 2 diabetes
Type 2 diabetes is a major health issue, and it currently affects millions of people around the world. It is characterized by high levels of sugar in the blood due to insulin resistance or low ability to produce insulin.
For some reason, drinking coffee greatly reduced the risk of developing type 2 diabetes.
Studies show that people who drink more coffee have a 23-50% lower risk of this disease.
One study showed a drop of 67%. According to a major review of 18 studies in a total of 457,922 people, each daily cup of coffee was associated with a 7% lower risk of developing type 2 diabetes.https://www.ncbi.nlm.nih.gov/pubmed/20008687 https://www.ncbi.nlm.nih.gov/pubmed/18842784
It may protect against Alzheimer’s disease
Alzheimer’s disease is the most common neurodegenerative disease and the leading cause of dementia worldwide, usually affects people over 65 years old, and there is no known treatment.
However, there are many things you can do to prevent the disease from occurring in the first place. This includes healthy diet and exercising, but drinking coffee may also be effective. Many studies show that coffee drinkers have a 65% lower risk to have Alzheimer’s disease. https://onlinelibrary.wiley.com/doi/full/10.1046/j.1468-1331.2002.00421.x
Depression is a serious mental disorder that causes a significant decrease in the quality of life. It is very common, as 4.1% of people in the U.S. currently meet the criteria for clinical depression.
In a study published by Harvard University in 2011, women who drank 4 or more cups of coffee a day were 20% less likely to develop depression. Another study conducted in 208,424 individuals found that those who drank 4 or more cups per day were 53% less likely to commit suicide.https://www.ncbi.nlm.nih.gov/pubmed/21949167 https://www.ncbi.nlm.nih.gov/pubmed/8604958
