1. Charakterystyka żywności / składnika

The food constituent that is the subject of the health claim is thiamine (also named vitamin B1), which is a well recognised nutrient and is measurable in foods by established methods.
Thiamine occurs naturally in foods and is authorised for addition to foods (Annex I of the Regulation (EC) No 1925/20064 and Annex I of Directive 2002/46/EC5). This evaluation applies to thiamine 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, thiamine, which is the subject of the health claims, is sufficiently characterised.

2.2. Czynności serca (ID 20)

The claimed effect is “normal cardiac function”. The Panel assumes that the target population is the general population.
The Panel considers that normal cardiac function is beneficial to human health.

3. Naukowe uzasadnienia wpływu na zdrowie człowieka

Thiamine (as thiamine diphosphate, a co-enzyme for several oxidative decarboxylation reactions and for transketolase) has a central role in energy-yielding metabolism, especially in the metabolism of carbohydrates and of branched-chain amino acids (Bender, 1999; EC, 2003). Thiamine (as thiamine triphosphate), has a function in nerve conduction (Bender, 1999; IoM, 1998). Thiamine deficiency can result in three distinct syndromes: Beriberi, a chronic peripheral neuritis, which may or may not be associated with heart failure and oedema, acute pernicious (fulminating) beriberi, in which heart failure and life-threatening metabolic acidosis predominate, with little or no evidence of peripheral neuritis, and central nervous system disturbances, Wernicke's encephalopathy with Korsakoff's psychosis (SCF, 1993).

3.2. Czynności serca (ID 20)

Thiamine has a role in energy metabolism in all cells including cells of the cardiac system (Bender, 1999; IoM, 1998).
The Panel concludes that a cause and effect relationship has been established between the dietary intake of thiamine and the normal cardiac function. However, the evidence provided does not establish that inadequate intake of thiamine leading to impaired cardiac function occurs in the general EU population.

4.2. Czynności serca (ID 20)

The Panel considers that the following wording reflects the scientific evidence:
“Thiamine contributes to the normal function of the heart”.

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 thiamine as per Annex to Regulation 1924/2006. Tolerable Upper Intake Levels (UL) have not been established for thiamine in children, adolescents and adults. The target population is the general population.
