4. During the during the 6th century BC. Food was classified into "hot"
(for example, meats, blood, ginger, and hot spices) and "cold"
(green vegetables) in China, India, Malaya, and Persia.
Ho the Physician from China concluded that diseases are caused
by deficiencies of elements (fire, water, earth, wood, and metal).

5. Around 475 BC,Anaxagoras
(Turkey) stated that food is
absorbed by the human body
and, therefore, contains
generative components,
suggesting the existence of
nutrients.

7. Galen
Galen (Greek) during first century AD,
believed in the four elements
(water, earth, fire and air) combine into
"complexion", which combines into states
(four Temperaments) (Mizaj)
The states are made up of pairs of
attributes (hot and moist, cold and moist,
hot and dry, and cold and dry).

8. James Lind
James Lind, a physician in the
British navy, performed the
firstscientificnutrition experiment
in 1747. Lind discovered
thatlimejuice saved sailors that
had been at sea for years, a deadly
and painful bleeding disorder
(scurvy). Between 1500 and 1800,
an estimated two million sailors had
died of scurvy.Due to this practice
British sailors became known as
"limeys."The essentialvitamin
Cwithin citrus fruits would not be
identified by scientists until 1932.

Antoine Lavoisierdiscovered the
details of metabolism,
demonstrating that
theoxidationof food is the source
of body heat.
