How Does Coffee Protect Against Dementia and Alzheimer’s?

Coffee is a beverage enjoyed by millions of people throughout the world.  While it may be adapted to enjoy differently in the various regions, it usually contains caffeine.  Additives such as sugar or milk and creamer are mixed in with coffee to change the taste.  

In some areas, such as Italy, it is enjoyed with a more bitter taste, while in the U.S. coffee has been adapted in many different creations with flavored syrups and much more.  Still, coffee and the caffeine it contains has some excellent health benefits, including protection against Alzheimer’s and dementia.

Protection Against Alzheimer’s

Alzheimer’s is a life-changing ailment. Caregivers and Alzheimer’s patients experience changes with the disease, including adaptations to make their lives more comfortable. Coffee can help protect against this disease. Studies have shown that coffee has effects on our brains, such as reducing inflammation.

This helps delay Alzheimer’s and even helps with those that already may have a mild case. Coffee is enjoyed by many because it seems to help wake us up.  This is because the caffeine in your morning cup helps aid in the management of specific proteins that can lead to Alzheimer’s.

Protection Against Dementia

While studies can’t confirm an absolute verdict, research has shown that caffeine in coffee and black tea could decrease the risk of dementia. Coffee and particularly the caffeine in coffee improves our brain function and abilities. One study showed the observation of several thousand women over the period of ten years.

It showed that those that drank about three cups of coffee per day decreased the risk of dementia by over 35%. In many Alzheimer’s cases too, they showed that approximately three, 8-ounce cups a day could help reduce the onset of the disease.  

Protection Against Other Ailments

Drinking approximately two to four cups a day can help reduce the risk of other diseases and ailments too. It Is suggested that in combination of ingesting the appropriate amounts of caffeine, you should exercise and get plenty of sleep to boost your health. Caffeine has been shown to potentially reduce the risk in Type 2 diabetes, lower the risks of heart attack and stroke, and lower the risks of Parkinson’s as well as liver cancer.  It also helps fight off depression symptoms and can boost your energy.

Volume Matters

There are many different recommendations from various studies on how much caffeine is actually beneficial.  Many suggest that 400mg or less of caffeine can produce excellent health benefits and can potentially ward off certain diseases or at least reduce the risk of obtaining them.

Others state that four cups or less of coffee will deliver the appropriate amount of caffeine.  Any more than this and coffee drinkers may experience upset stomachs, elevated heart rates, shakiness, and fatigue after the caffeine wears off.

Quality Matters

In order to reap the health benefits contained in your cups of coffee, it is important to pay attention to its contents. Heaping sugar and artificial creamers or additives severely depletes the benefits of your coffee.  

Your body will be focused on processing these harmful additions rather than using the caffeine to help boost brain function.  If you can, try to enjoy your coffee black. If you want to adjust your coffee to your liking and need an additive, try using soy or almond milk and healthier alternatives such as Stevia.

While many studies do not have definitive answers, researchers are leaning towards the positive affirmations of the studies that show that coffee and its contents can potentially reduce the risk of Alzheimer’s dementia, and several other diseases such as liver cirrhosis.
