BOB DOUGHTY: This is SCIENCE IN THE NEWS, in VOA Special English. I’m Bob Doughty.
FAITH LAPIDUS: And I’m Faith Lapidus. This week, we tell about vitamins.
(MUSIC)
BOB DOUGHTY: Many jobs must be done with two people. One person takes the lead. The other helps (a bit off). It is this cooperation (a bit off) that brings success.
So it is with the human body. Much of our good ("oo" sound, not "u" sound, like "look", "cook") health depends on the cooperation between substances. When they work together, chemical reactions take place smoothly. Body systems are kept in balance.
Some of the most important helpers in the job of good health are the substances we call vitamins.
