- Witamina C przyczynia się do prawidłowego funkcjonowania układu nerwowego
1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claim is vitamin C (L-ascorbic acid, ascorbate), which is a well recognised nutrient and it is measurable in foods by established methods.
Vitamin C occurs naturally in foods. Ascorbic acid and its salts (ascorbates) are the forms authorised for addition to foods and for use in food supplements (Annex II of the Regulation (EC) No 1925/20065 and Annex II of Directive 2002/46/EC6). This evaluation applies to vitamin C 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, vitamin C, which is the subject of the health claim, is sufficiently characterised.
2.5. Funkcjonowanie układu nerwowego (ID 133)
The claimed effect is “neurological system function”. The Panel assumes that the target population is the general population.
The Panel considers that normal function of the nervous system is beneficial to human health.
3. Naukowe uzasadnienia wpływu na zdrowie człowieka -
The evidence provided by consensus opinions/reports from authoritative bodies and reviews shows that there is good consensus on the role of vitamin C in the body (Bender, 2003; Garrow et al., 2000; IoM, 2000; NNR, 2004; Sadler et al., 1999; Shils et al., 2006; EVM, 2002). Vitamin C is an electron donor, or reducing agent, and its functions are attributable to this action (Shils et al., 2006). On the one hand, vitamin C acts as a major free-radical scavenger in the body, and as electron donor (and cofactor) for eight human enzymes, three of which participate in the biosynthesis (and cross-linking) of collagen and other components of the connective tissue, two of them are required in the biosynthesis of carnitine, one in tyrosine metabolism and two in the biosynthesis of the catecholamines adrenaline and noradrenaline (which act as neurotransmitters) and in the amidation of peptide hormones.
3.5. Funkcjonowanie układu nerwowego (ID 133)
Vitamin C is needed as a cofactor of dopamine -monooxygenase for the biosynthesis of noradrenaline (and adrenaline). Both catecholamines act as neurotransmitters. Manifestations of infantile scurvy include irritability, whereas hypochondriasis, depression and confusion have been described in adults with scurvy. These symptoms have been attributed to an impaired function of
dopamine -monooxygenase (Sadler et al., 1999; Shils et al., 2006; IoM, 2000).
The Panel concludes that a cause and effect relationship has been established between the dietary intake of vitamin C and normal function of the nervous system.
4.3. Funkcjonowanie układu nerwowego (ID 133)
The Panel considers that the following wordings reflect the scientific evidence: “Vitamin C contributes to the normal function of the nervous system.”
5.1. Ochrona DNA, białek i lipidów przed uszkodzeniem oksydacyjnym (ID 129, 138, 143, 148), tworzenie kolagenu (ID 130, 131, 136, 137, 149), funkcjonowanie układu nerwowego (ID 133), wchłanianie żelaza niehemowego (ID 132), funkcjonowanie układu odpornościowego (ID 134), and metabolizm energetyczny (ID 135)
The Panel considers that in order to bear the claims a food should be at least a source of vitamin C as per Annex to Regulation 1924/2006. Such amounts can be easily consumed as part of a balanced diet. The target population is the general population.
