1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is zinc, which is a well recognised nutrient and is measurable in foods by established methods. Zinc 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 zinc 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, zinc, which is the subject of the health claims, is sufficiently characterised.
2.8. Utrzymanie prawidłowego stanu włosów (ID 412)
The claimed effect is “significant effect on building of hair and nails”. The Panel assumes that the target population is the general population.
The Panel considers that maintenance of normal hair is a beneficial physiological effect.

The claimed effect is “significant effect on building of hair and nails”. The Panel assumes that the target population is the general population.
The Panel considers that maintenance of normal nails is a beneficial physiological effect.
3. Naukowe uzasadnienia wpływu na zdrowie człowieka -
Zinc is present in all tissues. It has essential structural, regulatory or catalytic roles in many enzymes. It maintains the configuration of a number of non-enzymatic proteins such as pre-secretory granules of insulin, some mammalian gene transcription proteins and thymulin. It facilitates hormone and receptor binding at membrane and nuclear levels, and it may maintain integrity of biomembranes. Consequently zinc participates in gene expression and in the mechanisms and control of major metabolic pathways involving proteins, carbohydrates, nucleic acids and lipids (SCF, 1993; DoH, 1991). Human zinc deficiency symptoms include retarded growth, depressed immune function, skin lesions, skeletal abnormalities, impaired reproductive ability and behavioural abnormalities such as changes in mood, loss of affect and emotional lability, anorexia, dysfunction of smell and taste, irritability and depression (SCF, 2003; EVM, 2002, Cousins, 2006).
3.6. Utrzymanie prawidłowego stanu włosów (ID 412)
Clinical manifestations of marginal to severe human zinc deficiency include various epithelial lesions. After the onset of dermatitis, the hair may become hypopigmented and acquire a reddish hue. Patchy loss of hair is a feature of zinc deficiency. Akrodermatitis enteropathica, an autosomal recessive disorder caused by a defect in zinc absorption, is characterised by extensive dermatitis, growth retardation, diarrhoea, hair loss and paronchya (King and Cousins, 2006).
The Panel concludes that a cause and effect relationship has been established between the dietary intake of zinc and maintenance of normal hair. However, the evidence provided does not establish that inadequate intake of zinc leading to impaired maintenance of normal hair occurs in the general EU population.
3.7. Utrzymanie prawidłowego stanu paznokci (ID 412)
Clinical manifestations of marginal to severe human zinc deficiency include various epithelial lesions. Nail dystrophy has been reported as a symptom of zinc deficiency (King and Cousins, 2006).
The Panel concludes that a cause and effect relationship has been established between the dietary intake of zinc and maintenance of normal nails. However, the evidence provided does not establish that inadequate intake of zinc leading to impaired maintenance of normal nails occurs in the general EU population.
4.5. Utrzymanie prawidłowego stanu włosów (ID 412)
The Panel considers that the following wording reflects the scientific evidence: “Zinc contributes to the maintenance of normal hair”.

The Panel considers that the following wording reflects the scientific evidence: “Zinc contributes to the maintenance of normal nails”.
5. Warunki i możliwe ograniczenia stosowania oświadczenia
The Panel considers that in order to bear the claim a food should be at least a source of zinc as per Annex to Regulation (EC) No 1924/2006. The target population is the general population. Such amounts can be easily consumed as part of a balanced diet. Tolerable Upper Intake Levels (ULs) have been established for zinc in children, adolescents, adults, pregnant and lactating woman (SCF, 2003).
