Te min proteïne, bv. kwashiorkor.

Te min vitamiene, bv. skeurbuik en beri-beri.

Oorvoeding:

Te veel van sekere voedingstowwe, bv. vetsug.

Klasaktiwiteit: PLAKKAAT

  • Versamel inligting oor verskeie voedingsiektes – verdeel in groepe en maak 'n plakkaat om sekere siektes aan die klas te verduidelik.
  • Die klas moet ‘n tabel skep en voltooi met die volgende hofies:
  • Naam van siekte
  • Tekort aan
  • Simptome
  • Weefsels geaffekteer
  • Die siektes is soos volg:
  • Skeurbuik
