Health benefits of decaffeinated coffee

Decaf coffee reduces the risk of incurring diabetes.

The high anti-oxidant levels of decaf will protect the cells from damage that can lead to diabetes. The decaffeination process will not eliminate chlorogenic acid which is the substance that helps regulate blood glucose levels

Cancer prevention.

Decaf still contains high levels of anti-oxidants that can prevent conditions associated with the aging process and cancer. Studies show that regular decaf drinkers have reduced risks of incurring colon cancer. For female drinkers, the risks of breast cancer are also reduced.

Decreased risk of heart problems.

Caffeine has been linked to heart conditions like irregular palpitations, heart attacks, and strokes. Since it has been removed, drinkers are less likely to develop any heart conditions

Prevention of mental decline due to old age and Alzheimer's disease.

The polyphenols found in coffee beans are not lost during the decaffeination process. These substances are responsible in boosting the brain's cognitive abilities, thus further improving memory.
These health benefits of decaf coffee cannot be dismissed as mere theories because proofs have been established with the studies that have been conducted. It may not be able to perk anyone up as effectively as regular coffee, but it will ensure good health and long life.

I resisted giving up regular coffee for years and would order half caf half decaf, but after my hospital stay in the fall of 2013, I gave up all caffeine. Also learned to brew my own, which I've gotten used to. My favorite decaf story: I ordered a cup of 1/2 regular coffee, 1/2 decaf, and the clerk asked if I wanted the decaf on the top or the bottom. This is why we have minimum wage jobs.
