Iodine Nutrition in Latin America

(Eduardo Pretell, Rubén Grájeda)
In the Latin American Region, about 90% of the population is consuming adequatelyiodized salt. But sustainability of iodized salt programs and problems of iodine excess remain major challenges ...

Varying salt iodine content and ahigh goiter rate in school childrenin Paraiba, Brazil

(Alane Abrantes Nogueira de Pontes and Luís Fernando Fernandes Adan)
Iodine deficiency is still a serious publichealth problem in many countries in theworld. Brazil is a country historically affected by iodine deficiency in most of its territory,and severe endemic goiter and creti-nism were reported by many early authors. A law ordering the iodization of all salt forhuman consumption as the main strategyto correct IDD was passed in 1953.However, the iodization level (10 ppm of iodine) was considered low ...

Iodine deficiency persistsin northern Argentina

(Eduardo Pretell and Hugo Niepomniszcze)
Moderate-to-severe endemic goiter due to iodine deficiency has been historicallyfound in the western part of Argentina,particularly in the Andean foothills,as wellas in the northern part of the country, including the Provinces of Jujuy, Salta, Catamarca, Tucuman, Santiago del Estero, La Rioja, San Juan, Mendoza, San Luis, Neuquen, Formosa, Chaco, and Misiones, as well as the western regions of Cordoba, La Pampa, Rio Negro, Chubut, SantaCruz and Tierra del Fuego, and the northern regions of Santa Fe and Corrientes ...

Iodine excess in Chile

(Santiago Muzzo and Eduardo Pretell)
The Chilean population was moderately iodine deficient prior to salt iodization. A law mandating the iodization of all saltfor human consumption was passed in1960. It was implemented in 1979 and the level of iodization was fixed at 100 ppm. Enforcement of the law was interruptedfrom 1984 to 1991, but the salt iodizationprocess was maintained by the large producers of iodized salt. An early study inschool age children carried out in Santiago City in 1982, before the law was fullyenforced, found a mean urinary iodine (UI) of 109±78 µg/gr creatinine (cr), with 58.2% of samples <100 µg/gr cr ...

Peru celebrates 25 years ofsustained elimination of IDD

(Eduardo A. Pretell and Ana Maria Higa)
The Peruvian IDD Control Program isone of the few programs that has eliminated iodine deficiency as a public health problem and has also sustained its success. The story of the elimination of iodinedeficiency in Peru is a long struggle, lasting more than a half a century, since the lawmandating the iodization of salt was approved in 1940 ...

Elimination of IDD and emergingrisk of iodine excess in Paraguay

(Elsi Ovelar, Juana Redondo, Zuni Zarza, Nilda Gonzalez, Jorge Jara and Eduardo A. Pretell )
Paraguay has a long history of iodine deficiency. In the early 1950s, the total goiterrate was 50%. A law mandating the iodization of salt was passed in 1958, establishing the iodization level at 60-100 ppm. All saltconsumed in the country is imported. Therefore, iodization plants were installedat the entrance ports and the law stated that all salt entering the country should beiodized either at customs or in registerediodization plants in the country ...

A well-monitored iodized salt programprovides adequate iodine intake forVenezuelan pregnant women

(Luis A. Caballero)
The Andean region of Venezuela, includingthe States of Tachira, Merida and Trujillo, historically was an area of endemic iodinedeficiency. The national iodized salt program corrected iodine deficiency in this region, and in 1999, an external evaluationby a team of experts of PAHO/WHO, UNICEF and ICCIDD, declared Venezuela virtually free of IDD ...

Raising the World’s I.Q.

(Nicholas D. Kristof)
Travelers to Africa and Asia all have their favorite forms of foreign aid to “make adifference.” One of mine is a miracle substance that is cheap and actually makes people smarter. Unfortunately, it has oneappalling side effect. No, it doesn’t makeyou sterile, but it is just about the leastsexy substance in the world. Indeed,because it’s so numbingly boring, few people pay attention to it or invest in it. (Or dare write about it!) It’s iodized salt ...
