1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is iodine, which is a well recognised nutrient and is measurable in foods by established methods.
Iodine occurs naturally in foods and is authorised for addition to foods (Annex I of the Regulation (EC) No 1925/20066 and Annex I of Directive 2002/46/EC7). This evaluation applies to iodine naturally present in foods and those forms authorised for addition to foods (Annex II of the Regulation (EC) No 1925/2006 and Annex II of Directive 2002/46/EC).
The Panel considers that the food constituent, iodine, which is the subject of the health claims, is sufficiently characterised.
2.1. Udział w prawidłowym przebiegu procesów poznawczych i funkcji neurologicznych (ID 273)
The claimed effect is “neurological/mental and cognitive development (including in utero)”. The Panel assumes that the target population is the general population.
In the context of the clarifications provided by Member States, the Panel assumes that the claimed effect is related to normal cognitive and neurological function.
The Panel considers that contribution to normal cognitive and neurological function is a beneficial physiological effect.
3. Naukowe uzasadnienia wpływu na zdrowie człowieka -
Iodine is an essential constituent of the thyroid hormones, which have important modifying or permissive roles in growth and development, and there is a large body of evidence indicating a crucial role for iodine in growth and development (Sadler et al., 1999; IoM, 2002; Garrow et al., 2000; WHO, 2001; Strain and Cashman, 2009). The biological function of the thyroid hormones encompasses the regulation of energy-yielding metabolism and endocrine function by cellular oxidation, thermoregulation, intermediary metabolism, protein and enzyme synthesis, nitrogen retention, gluconeogenesis and pituitary gonadotropins (Houston, 1998; SCF, 2002). A wide spectrum of iodine deficiency disorders has been observed, depending on the degree of deficiency and the life stage at which the deficiency occurs. These disorders include goitre, hypothyroidism and impaired mental function, including the most severe forms of endemic cretinism (congenital, severe, irreversible mental and growth retardation). Other symptoms of severe iodine deficiency disorders (arising from iodine deficiency in the foetus) include deaf-mutism, squint, disorders of stance and gait, and dry skin and swollen subcutaneous tissue (Delange, 2000; EVM, 2003; WHO, 2007). Most countries in the world have some degree of iodine deficiency disorders including several European countries (Stanbury et al., 1998; WHO, 1999; Delange, 2002, WHO, 2007).
3.1. Udział w prawidłowym przebiegu procesów poznawczych i funkcji neurologicznych (ID 273)
Iodine deficiency disorders encompass suboptimal neurological function, apathy and mental sluggishness (SCF, 2002). The WHO (2001) describes a wide spectrum of iodine deficiency disorders which include retarded mental and physical development in children and adolescents, and impaired mental function and reduced cognitive capacity for people of all ages.
The Panel concludes that a cause and effect relationship has been established between the dietary intake of iodine and contribution to normal cognitive and neurological function.
4.1. Udział w prawidłowym przebiegu procesów poznawczych i funkcji neurologicznych (ID 273)
The Panel considers that the following wording reflects the scientific evidence: “Iodine contributes to normal cognitive and neurological function”.
5. Warunki i możliwe ograniczenia stosowania oświadczenia
The Panel considers that in order to bear the claims a food should be at least a source of iodine as per Annex to Regulation (EC) No 1924/2006. Tolerable Upper Intake Levels (ULs) have been established for iodine in children, adolescents, adults, pregnant and lactating women (SCF, 2002). The target population is the general population.
