Outlines

• You are what you eat

• Milestones in nutritional sciences

• World food and nutrition problems

• Prevention strategy

Hungary Planet Part I to III:What the World Eat?

• Time 的網頁上展現 25 個家庭一週的飲食內容與費用

• 哪個家庭的飲食與自家的飲食比較相似?• 您能接受和不能接受的飲食是哪一家?• 您的飲食花費比較接近哪一個國家?

營養定理• 營養 Nutrition : 生物獲得滋養的生命程序 ,

利用外界的食物來維持生長和修補組織  • 營養素 Nutrients : 食物供應的維持生命所需

的成份 – 必需營養素 Essential nutrients:

• 缺乏導致缺乏症– 非必需營養素 Non-essential nutrients

• 缺乏不會導致缺乏症• 營養素與健康的關係

– 因果關係:具有必需性– 關聯性 / 機率性:風險、危險因子

領域特色與重點• 食品科學

– 農作物從收穫到入口前的各項知識和技術

• 營養科學– 食物入口後,人體利用食物的各項生理 / 生化程序的知識和研究技術

• 醫學– 認識與治療人體疾病的知識與技術

東西共通的保健觀

• 醫食同源• Hippocrates, the "Father of Medicine“

– 400 B.C. – said to his students, "Let thy food be thy medicine and

thy medicine be thy food".  – He also said  “A wise man should consider that health

is the greatest of human blessings.”

Nutritional concepts arise from chemistry and physiology: 1750-1840

• 1770 -- Antoine Lavoisier, the “Father of Nutrition and Chemistry”– 體溫 / 生命的化學機制– He discovered the actual

process by which food is metabolized. 

– He also demonstrated where animal heat comes from. 

– In his equation, he describes the combination of food and oxygen in the body, and the resulting giving off of heat and water.

– He then studied energy expenditure using calorimetry .

The first calorimeter

built by Lavoisier (1734-1794)

Indirect calorimetry

Wilbur Olin Atwater (1844-1907)Nutrition and Exercise

Cycle ergometer used by Atwater andhis colleague Benedict in their studies on exercise metabolism. Before Atwater died in 1907, he had completed more than 500 energy-balance experiments

實驗動物應用於食物營養研究

• Animal study is relevant to human nutrition

• 1897 – Christiaan Eijkman, a Dutchman working in Java, and thiamin (B1)

• chickens – fed white rice diet, developed the

symptoms of Beriberi – fed the unprocessed brown rice (with

the outer bran intact), no disease. 

• Eijkman then fed brown rice to his patients and they were cured.  

• The Nobel Prize in Physiology or Medicine 1929

維他命說

• 1912 – Dr. Casmir Funk (German) was the first to coin the term “vitamins” as vital factors in the diet. 

The Nobel Prize and the Discovery of Vitamins

• 圖像: the Genius of Medicine holding an open book in her lap, collecting the water pouring out from a rock in order to quench a sick girl's thirst.

• 文字 Inventas vitam juvat excoluisse per artes(Word for word: inventions enhance life which is beautified through art.)

• The words are taken from Vergilius Aeneid, the 6th song, verse 663;

Lo, God-loved poets, men who spake things worthy Phoebus' heart;and they who bettered life on earth by new-found mastery

日本食育基本法 (2005)

http://www.e-shokuiku.com/index.html

《食育基本法》制訂於 2005 年 6 月(平成十七年法律第六十三号),其中將食育定義為: 「學習食物相關的知識,並養成正確選擇食物的能力」

結 論

• 1. 飲食的質與量影響個人與人類族群的健康和生存。

• 2. 個人學習營養的目的在於– 認識食物相關的知識,– 並養成正確選擇食物的能力。

• 3. 關心並認識國家和國際的糧食與健康趨勢和政策,合力營造健康飲食環境。
