Antioxidants“One drink of
beer or wine provides
equivalent increases in
plasma antioxidant
activity”

What are antioxidants?
• Antioxidants are molecules that detoxify Reactive Oxygen Intermediates (ROIs) in the body by surrendering electrons http://www.asnutrition.com/zat_antioxidants.asp
![Page 8: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/8.jpg)
How antioxidants work
• Reactive Oxygen Intermediates = Free Radicals
• Free Radicals + Body Tissue (oxidation) Cellular Damage Cell Death or Mutation Disease
• Free Radical + Antioxidant Neutral Unreactive Complex
![Page 9: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/9.jpg)
How antioxidants work
• Low-density lipoprotein (LDL) is oxidized by free radicals immune system cells recognize and engulf oxidized LDL formation of atherosclerotic plaques in arterial wall
• Antioxidants prevent oxidation of LDL, not blood plasma - Therefore antioxidants help
prevent atherosclerosis
![Page 10: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/10.jpg)
• Free radicals cause DNA damage mutations or irreversible damage cancer
• Antioxidants neutralize free radicals and therefore reduce risk of cancer

Summary
• Free radicals are harmful because they oxidize body tissue
• This causes cell mutation, cell
death, and disease
![Page 12: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/12.jpg)
Polyphenols“Polyphenols, the compounds in plants that
help prevent UV damage from the sun and make the plant cell wall strong, are believed
to have antioxidant benefits when consumed by humans.”
![Page 13: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/13.jpg)
Chemical structure
• A polyphenol is comprised of one or more aromatic rings bonded with hydroxyl groups.
• Some chemical structures:
example of a catechin
![Page 14: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/14.jpg)
Polyphenols and Wine
• Wine contains a variety of polyphenols.
• The type and concentration of polyphenols are dependent upon: - type of grapes - aging process - manufacturing process
![Page 15: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/15.jpg)
Polyphenols and Beer
• The polyphenols in beer come from hops
• The type and concentration of polyphenols differ from those found in wine
• Therefore, it is not reasonable to compare beer to wine
![Page 16: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/16.jpg)
“Study finds beer as healthy as wine.”
Beer vs. Wine
![Page 17: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/17.jpg)
Polyphenols
• The structure of polyphenols differ between beer and wine - Therefore, they would not exhibit the
same health benefits
![Page 18: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/18.jpg)
Summary
• Components of wine are never constant and change according to where it was made and the age of the wine
• Specific components (antioxidants) are beneficial, however, the concentration of each component is unknown
![Page 19: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/19.jpg)
Gout“Specifically,
they found that two or more beers a day more than
doubles the risk of gout…”
![Page 20: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/20.jpg)
What is gout?
• A form of inflammatory arthritis• Affects the joints of the body • Caused by elevated levels of uric acid in the blood•Uric acid is the break down product of purines
![Page 21: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/21.jpg)
Alcohol and Gout
•Beer contains purines•Wine does not - Consumption of beer raises the risk of gout, but wine does not
![Page 22: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/22.jpg)
Hormesis
“…“hormesis” – small doses of a toxic substance can have beneficial effects, while a large amount is harmful.”
![Page 23: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/23.jpg)
What is hormesis?
•The notion that small doses of a toxin can be healthful
•This term is most often applied to radiation
![Page 24: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/24.jpg)
Alcohol and Hormesis
• Alcohol is not toxic in small quantities
- Therefore alcohol is not considered a toxic
substance
![Page 25: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/25.jpg)
The Bottom Line
• Scientific Research - From inquisition to
innovation• With the media as a
liaison• What is lost in
translation?
![Page 26: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/26.jpg)
Antioxidants• Article

Polyphenols• Article
- Found in plants and have antioxidant benefits- Are a compound that adds strength to plant cell walls
• Science- Protect plants from pathogens- No information was found regarding cell wall strength and polyphenols
![Page 28: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/28.jpg)
Health Benefits• Article
- Wine has 20x more polyphenols than beer- Wine is as healthy as beer
• Science- Polyphenol concentration is dependant on manufacturing process- Beer and wine are not equitable comparisons
![Page 29: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/29.jpg)
Scientific Terminology
• Article- 2 beers doubles the risk of gout- Alcohol has an hormetic effect on health
• Science-1 beer increases the risk of gout by 2.5X- Hormesis is inappropriately used in conjunction with alcohol consumption
![Page 30: Is Beer as Healthy as Wine? Group 6 – Jo Ho, Karim Mohamed, Katrina Watson, Gina Vaz, Kelly Shum, Jodi Branton, Leah McManus, and Alisha Seller Special.](https://reader036.fdocuments.us/reader036/viewer/2022062516/56649da25503460f94a8f279/html5/thumbnails/30.jpg)
Conclusion
Unless individuals begin reading more critically and journalists disseminate information more
accurately, science in the popular media will continue to
be….
