Benefits of Coffee in our Body
Coffee is a brewed drink prepared from roasted coffee beans, the seeds of berries from certain flowering plants in the Coffea genus. From the coffee fruit, the seeds are separated to produce a stable, raw product: unroasted green coffee. It is a beverage that's brewed with very hot or boiling water, and coffee beans which have already been roasted and ground. Coffee beans are sourced from coffee plants, members of the botanical genus Coffea.
Coffee beans are actually seeds. It's only after they have been dried, roasted and ground that they can be used to brew the humble zip. If unprocessed coffee seeds are planted, they can germinate and grow into coffee plants. The seeds are normally planted in large, shaded beds.
People most commonly drink coffee to relieve mental and physical fatigue and to increase mental alertness. Coffee is also used to prevent Parkinson disease, dementia, and many other conditions, but there is no good scientific evidence to support many of these uses.
Coffee is a beloved beverage known for its ability to fine-tune your focus and boost your energy levels. In fact, many people depend on their daily cup of joe right when they wake up to get their day started on the right foot.
In addition to its energizing effects, coffee has been linked to a long list of potential health benefits, giving you all the more reason to get brewing.
This article takes an in-depth look at 7 of the top evidence-based benefits of coffee.
1. Boosts energy levels
Coffee contains caffeine, a central nervous system stimulant that is known for its ability to fight fatigue and increase energy levels.
This is because caffeine blocks the receptors of a neurotransmitter called adenosine, and this increases levels of other neurotransmitters in your brain that regulate your energy levels, including dopamine.
One small study found that consuming caffeine increased time to exhaustion during a cycling exercise by 12% and significantly reduced subjective levels of fatigue in participants.
Another study had similar findings, reporting that consuming caffeine before and during a round of golf improved performance, increased subjective energy levels, and reduced feelings of fatigue.
Coffee contains caffeine, a stimulant that has been shown to increase energy levels and decrease fatigue by altering levels of certain neurotransmitters in the brain.
2. May be linked to a lower risk of type 2 diabetes
Some research suggests that consuming coffee regularly could be associated with a decreased risk of developing type 2 diabetes over the long term. In fact, one review of 30 studies found that each cup of coffee people consumed per day was linked to a 6% lower risk of developing type 2 diabetes.
This is thought to be due to coffee’s ability to preserve the function of the beta cells in your pancreas, which are responsible for producing insulin to regulate blood sugar levels. Plus, it’s rich in antioxidants and may affect insulin sensitivity, inflammation, and metabolism all of which are involved in the development of type 2 diabetes.
Regular coffee consumption may be linked to a lower risk of developing type 2 diabetes over the long term.
3. Could support brain health
Although studies have turned up mixed results, some research suggests that coffee may help protect against certain neurodegenerative disorders, including Alzheimer's disease and Parkinson's disease.
Another review of 11 observational studies in more than 29,000 people also found that the more coffee people consumed, the lower their risk of Alzheimer’s disease.
Additionally, several studies have demonstrated that moderate coffee consumption could be associated with a lower risk of dementia and cognitive.
4. May promote weight management
According to some research, coffee could alter fat storage and support gut health, both of which may be beneficial for weight management.
For example, one review of 12 studies concluded that higher coffee consumption could be associated with decreased body fat, especially in men.
In another study, increased coffee intake was linked to decreased body fat in women.
Furthermore, one study found that people who drank one to two cups of coffee per day were 17% more likely to meet recommended physical activity levels, compared with those who drank less than one cup per day.
Higher levels of physical activity could help promote weight management. Coffee could help support weight management and may be linked to decreased body fat. One study also found that people who consumed coffee were more likely to be physically active.
5. Linked to a lower risk of depression
Some studies have found that drinking coffee could be associated with a lower risk of depression.
According to one review of seven studies, each cup of coffee people consumed per day was linked to an 8% lower risk of depression. Another study found that drinking at least four cups of coffee each day was associated with a significantly lower risk of depression, compared with drinking just one cup per day. What’s more, one study in more than 200,000 people showed that drinking coffee was linked to a lower risk of death by suicide.
6. Could protect against liver conditions
Interestingly, several studies suggest that coffee could support liver health and protect against disease. For instance, one study found that drinking more than two cups of coffee per day was linked to lower rates of liver scarring and liver cancer in people with liver disease.
Other research shows that the more coffee people drank, the lower their risk of death from chronic liver disease. Drinking one cup of coffee per day was tied to a 15% lower risk, while drinking four cups per day was linked to a 71% lower risk.
Another recent study found that coffee consumption was associated with decreased liver stiffness, which is a measure healthcare professionals use to assess fibrosis, the formation of scar tissue in the liver.
7. Supports heart health
Some research shows that drinking coffee may benefit heart health. In fact, one review found that drinking three to five cups of coffee per day was tied to a 15% reduced risk of heart disease.
Another review of 21 studies showed that drinking three to four cups of coffee daily was associated with a 21% lower risk of stroke. What’s more, one study in more than 21,000 people also found that increased coffee intake was associated with a significantly decreased risk of heart failure.
Some research shows that drinking coffee could be linked to a lower risk of heart disease, stroke, and heart failure.
Therefore, Coffee is a popular beverage that researchers have studied extensively for its many health benefits, including its ability to increase energy levels, promote weight management, enhance athletic performance, and protect against chronic disease.
Have enough courage to start and enough heart to finish.
