Coffee & Health
Transcript of Coffee & Health
A study shows protective and therapeutic roles of coffee against Alzheimer's disease (Chang & Ho, 2014)
Benefits could be from antioxidants
What is Coffee?
Is Coffee Protective against Cancer?
Several studies have shown no risk with drinking coffee and developing cancer
Heavy coffee consumption may protect against endometrial cancer (Gavrilyuk et al., 2014)
Another study shows coffee consumption to lower risk of developing bladder, colorectal, esophageal, and pancreatic cancer (Yu, Bao, Zou, & Dong, 2011)
Type II Diabetes
Regular coffee drinkers have a lower fasting blood glucose based on a study conducted on the Taiwanese population (Lin et al., 2011)
Not dependent on caffeine
Addition of sugar and creamer may alter beneficial effects
Study found coffee to reduce severity of liver cirrhosis
Reduced severity could be from antioxidant activity or a component with the liver enzymes
Still controversial (Neto et al., (2010)
Pros of Drinking Coffee

How much do People Love Coffee?
After harvesting, the cherries are processed
Processing leads to milling

Coffee cherries take a year to mature
Structural components of the coffee cherry
Commercial coffee varieties - Arabica & Robusta
National Coffee Association of U.S.A., Inc. n.d.
National Coffee Association of U.S.A.
Inviting aroma, pharmacological effects, and stimulatory properties (Neto et al., 2010)
Second most consumed beverage with 500 billion cups consumed annually (Bidel & Tuomilehto, 2013)
In USA, 12,000 Starbucks locations (Statistica, n.d.)
What are Causing these Beneficial Effects?
Cons of Drinking Coffee
Caffeine and Pregnancy
Caffeine component most often credited as being "bad" for health
Pregnant women are population of concern
Risk on bone health
Does Coffee affect Bone Health?
Not necessarily ...
Two separate studies found no link between coffee consumption and bone fracture of any kind
Hallstrom et al., 2013
Everyone reacts to coffee differently
Studies show that coffee can be beneficial to health
Be cautious when drinking coffee if suffering from insomnia and when pregnant
Caffeine in coffee can be harmful to the fetus
Pregnant women who drank high amounts of caffeine had a 60% greater chance of delivering a LBW baby (Chen et al., 2014)
Pregnant women who drank caffeine had a higher (25%) risk of miscarriage (Weng, Odouli, & Li, 2008)
Minimize caffeine intake during pregnancy or switch to decaffeinated coffee
Optimal antioxidant content is within 20 minutes after preparation (Cimpan, 2014)

Caffeinated coffee alters quality of sleep, even with just one cup after dinner (Lloret-Linares et al., 2012)
Lengthens the sleep latency
Increases the number of awakenings
