[Iodine levels in food and soil in different regions in Cameroon].

Iodine deficiency diseases (IDD) are a public health problem in many developing countries, such as Cameroon. They are often the consequence of insufficient iodine intake and/or the effect of thiocyanate in foods such as cassava; this chemical inhibits iodine fixation by the thyroid gland. One method of combatting these diseases is to counsel and encourage the consumptions of iodine-rich foods.
