Odd experiments by 'America's first physiologist' shed light on digestion
Date:4/24/2013

explains, not much was known about digestion. To gain insight about this vital function, Beaumont performed a series of 238 experiments on St. Martin intermittently over an eight-year period. In all, experiments were conducted at four different rustic military outposts spanning the unsettled Great Lakes region to the East Coast. Twice, Beaumont had to convince the reluctant St. Martin to return from Canada to his frontier lab to continue the experiments. Many of these experiments involved inserting bits of different foods tied to strings through the hole in St. Martin's stomach, pulling them out periodically to observe digestion. Beaumont also removed gastric juice, examining it to better understand its nature.

Seizing the Opportunity

Beaumont's observations, published in1833 in a lengthy book entitled "Experiments and Observations on the Gastric Juice and the Physiology of Digestion," form the basis of much of the early knowledge on digestion. Many of his observations have proven true with today's more sophisticated research techniques, Dean says.

For example, Beaumont discovered that hydrochloric acid is the main chemical responsible for breaking down food. He proposed the existence of a second important digestive chemical, which scientists now know is the enzyme pepsin. His experiments "digesting" food in a cup with St. Martin's extracted gastric juices showed that digestion is a chemical process, not merely a mechanical one caused by stomach muscle movement. His work also provided insights on how emotions, temperature, and physical activity can affect digestion.

From performing such intensive investigation in America's early days, Beaumont is now recognized as America's first physiologist, Dean says. Today, numerous hospitals are named after this physician-scientist.

Despite St. Martin's unusual wound, which never healed, he ended up outliving Beaumont and fathering numerous children.
