First, the benefits
1. Protection against different types of cancers
Hundreds of biologically active compounds including caffeine, flavonoids, lignans, and other polyphenols are found in roasted coffee. These and other coffee compounds have been shown to increase energy expenditure, inhibit cellular damage, regulate genes involved in DNA repair, and have anti-inflammatory properties.
2. It could reduce your risk of suicide
It was found that the caffeine contained in coffee not only stimulates the central nervous system but may also act as a mild antidepressant by boosting production of some neurotransmitters in the brain like serotonin, dopamine, and noradrenaline.
3. It may reduce the risk of Alzheimer’s and dementia.
A recent study found that drinking of 3-5 cups per day at midlife was associated with a decreased risk of dementia and Alzheimer’s by about 65 percent later in life.
4. Reduces your risk of type 2 diabetes
What researchers found was that those who increased their coffee consumption by more than one cup per day had an 11 percent lower risk of developing type 2 diabetes.
Now, the bad news
1. You could get addicted
Unless you drink decaf, coffee contains a high amount of caffeine. Caffeine is an addictive chemical that can create a dependency.
2. You could have more frequent urination
For years, people and even experts have named coffee as a diuretic. Continued studies have not linked the ingredients in coffee as contributing to frequent urination. So, if you drink a lot of coffee, expect a lot of that liquid to go to your bladder.
3. You could lose sleep
Consuming caffeine 6 hours before bedtime reduced total sleep time by one hour.
4. It could negatively affect your bones
No concrete evidence has been found. So, you could drink less coffee, or you could balance it out with milk, almonds, broccoli or other calcium-rich foods.
5. It could cause or worsen acid reflux
While the research is not concrete, try avoid brewing methods like espresso or french press that don’t use paper filters that catch oil droplets in the coffee that contain stomach irritants.
