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
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 .
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
