Is coffee healthy?

[Rasel Ali]

So many reasons coffee is a healthy drink. some reason is-

Weight loss

Caffeine may boost weight loss or prevent weight gain, possibly by:

suppressing the appetite and temporarily reducing the desire to eat

stimulating thermogenesis, so the body generates more heat and energy from digesting food

Weight loss products that are marketed as thermogenic may contain caffeine and ephedra, or ephedrine.

Research has not confirmed long-term results.

Alertness

A 75-mg serving of caffeine can increase attention and alertness, and a 160 to 600-mg dose may improve mental alertness, speed reasoning, and memory.

However, caffeine is not a substitute for sleep.

Sports performance

Caffeine can improve physical performance during endurance exercise.

The European Food Safety Agency (EFSA) recognize that caffeine can increase endurance performance, endurance capacity, and reduction in perceived exertion.

However, the effects on short-term, high-intensity exercise remain inconclusive.

Brain function

Caffeine affects adenosine receptors in the brain. Coffee also contains polyphenol antioxidants, and these, too, act on various pathways.

Studies have suggested that drinking coffee may help enhance some thinking skills and slow the mental decline that comes with age.

However, more research is needed to confirm this.

Alzheimer’s and Parkinson’s disease

Research has found that lifelong caffeine consumption may reduce the risk of developing Alzheimer’s disease.

Studies have also reported that people with higher coffee consumption have a lower risk of Parkinson’s disease.

Memory

Research from Johns Hopkins University suggests that a dose of caffeine after a learning session may help boost long-term memory.

Liver and colon

It has been suggested that caffeine enemas may help prepare the colon for an endoscopy or colonoscopy by supporting the excretion of bile through the colon wall.

Proponents claim that a caffeine enema increases the levels of glutathione, an antioxidant, and so it supports the natural processes of detoxification in the liver.

However, there is little evidence to support this theory.

Coffee consumption may help decrease the risk of cirrhosis and slow the rate of disease progression in hepatitis C infection. Observational studies have found that coffee may have protective benefits for people with hepatocellular cancer.

Eyelid spasm

There is some evidence that caffeine may help protect people from an eye disorder known as blepharospasm.

This condition, caused by abnormal brain function, makes people blink incessantly and can leave them functionally blind.

Cataracts

Researchers have found that caffeine may help protect the lens of the eye against damage that could lead to the formation of cataracts.

Skin cancer

Some scientists have suggested that caffeine may guard against certain skin cancers.

One team found that caffeine applied directly to the skin of mice helped prevent damaging ultraviolet (UV) light from causing skin cancer.

Others have linked the consumption of three cups of caffeinated coffee a day with a 21 percent lower risk of developing basal cell carcinoma in women, and a 10 percent lower risk in men, compared with drinking less than one cup per month.

Kidney stones

A study of 217,883 participants analyzed the association between caffeine intake and the risk of developing kidney stones.

Those who consumed more caffeine had a lower risk of developing kidney stones.

Mouth, throat, and other cancers

In a study of 968,432 men and women, participants who drank than 4 cups of coffee a day had a 49-percent lower risk of death from oral cancer, compared with those who drank no coffee at all or only an occasional cup.

Other possible cancer-related benefits include:

    lower risk of endometrial cancer
    reduced risk of prostate cancer
    protection against head and neck cancer
    protection against the recurrence of breast cancer

Stroke

Data for 34,670 women in Sweden without a history of cardiovascular disease indicated that women who drank more than one cup of coffee per day had a 22 to 25-percent lower risk of stroke compared with women who drank less.

Low or no coffee drinking appeared to be linked to an increased risk of stroke.

Type 2 diabetes

One longitudinal study found that participants who increased their coffee intake by more than one cup a day over a 4-year period had a 1 percent lower risk of developing type 2 diabetes compared with people who did not change their intake.

People who lowered their daily consumption by more than one cup of coffee showed a 17 percent higher risk for type 2 diabetes.

A study published in Diabetes Care in 2004 linked a high coffee consumption over a period of 4 weeks with increased fasting insulin concentrations.

However, the reasons for the link were unclear. It may be due to lowered insulin sensitivity, meaning the body does not use the insulin produced efficiently.

The team called for more investigation before asserting that high coffee consumption lowers risk for type 2 diabetes.
