History and General Flashcards
Dr. William Beumont
Army doctor
Stationed in fort mackinac in north michigan
Discovered many things through Alexio St. Martin’s stomach hole
Alexio St. Martin
French trappers, shot in the stomach at a bar
Allowed Beaumont to observe him
Unable to be healed by Beumont
Healed with an opening to the outside from shot wound
Daniel
Over 2000 years ago, when Daniel was a young israeli, captured and taken to Babylonian King
Enlisted to serve the king
In the bible; first recorded nutritional experiment over 2000 years ago; pulse and water vs. meat and wine for 10 days
Antoine Lavoisier
Designed the calorimeter
An aristocrat
french, father of nutrition, for work in chemistry, put weight measures in chemistry, designed calorimeter (measured heat produced by the body from work and consumption of varying amounts and types of food)
famous for the statement “life is a chemical process”
elected to french academy of science at age 24
was from aristocratic family so beheaded in the French Revolution in 1794
Lind
British naval doctor
Treaties on scurvy
(Recovery from citrus fruit)
Failed to recognize the importance of his observations
Credited as discovering the effects of citrus on scurvy and credited with the initial discovery of vitamin C (but he failed to recognize the importance of his observations)
he continued to credit humors (which we don’t believe in anymore) of digestive as being related to scurvy
Associated vit C with citrus fruit
Dr. Stephen Babcock
Best known for the Babcock test, which tests for milk fat. conceived the idea to feed dairy cattle feed from just one source all corn or all wheat plant. He placed 2 heifers on such diets, but when one died his animals were taken away and his attempts to conduct the experiment were denied by his experiment station director. His experiments led to the discovery of vitamins
His experiment was important because it was the first semi-purified diet used in economically important species and opened the golden age of nutrition
Had the idea to feed cows just material from a single source
(Either from wheat, corn, or oat)
Funk
Named vitamins
termed a vitamin a vitamin because he erroneously thought that vitamins contained amines, so he combined vital and amine to coin the term vitamin in 1911
What is the first recorded nutritional experiment?
Daniel ate vegetables and water to eat for 10 days
Results: Appeared fairer and fatter in flesh
What did Beumont discover together with Alexio St. Martin?
Determined the stomach was not a grinder
There is no area in the stomach that separates the good and the bad
Digestion takes place through digestive juices
Foods are all digested at the same time but at different rates
Stomach noises are just stomach contractions
Fat is digested slowly
Who was responsible for the health of the Limeys (British Navy)? Why are they called Limeys?
Dr. James Lind
They treated scurvy with limes
Called limeys because they put lemons, then called limes, on naval ships after Gilbert Blane pushed to do so
What was the significance of the single plant feeding experiment?
Either the corn contained something the wheat didn’t, or the wheat contained something toxic.
Discovery of vitamins
Who named vitamins after vital amines?
Idea came from thinking that factors that affected diet had amines in them
Funk
Who is credited with “Life is a chemical process”, and is called the Father of Nutrition?
Antoine Lavoisier
What are the major differences and similarities in composition between animals and the plant materials that serve as their food?
- Animals are mostly protein while most plants contain much lower levels of protein (soybeans and other oil seeds are exceptions)
- plants are mostly composed of carbohydrates, while animals only contain trace carbohydrates
- Animals store their extra energy as fat, but most plants do not (oil seeds are an exception)
- Animals have lots of minerals while plants contain minerals too but the types of minerals differ (animals have Ca&P, while Plants have P&K)
- Plants and animals have different compositions therefore we must balance diets by adding to the plant material animals eat, the extra nutrients they need to balance the diet.
What are the 5 things Dr. Beumont determined:
- he determined the stomach is not a grinder
- there is no spirit in the body directing foods to good purposes and discarding the bad
- digesting takes place by digestive juices secreted from the stomach
- foods are digested all at the same time but at different rates, not separately and sequentially as was thought
- fat is digested slowly and the stomach noises that occur are just contractions
