1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is selenium, which is a well recognised nutrient and is measurable in foods by established methods.
Selenium occurs naturally in foods and is authorised for addition to foods and for use in food supplements (Annex I of the Regulation (EC) No 1925/20066 and Annex I of Directive 2002/46/EC7). This evaluation applies to selenium naturally present in foods and to those forms authorised for addition to foods and for use in food supplements (Annex II of the Regulation (EC) No 1925/2006 and Annex II of Directive 2002/46/EC).
The Panel considers that the food constituent, selenium, which is the subject of the health claims, is sufficiently characterised.

The claimed effect is “joint function”. The Panel assumes that the target population is the general population.
The Panel considers that maintenance of normal joints is a beneficial physiological effect.

Selenium is an essential trace element. Twenty-five selenoprotein genes have been identified in the human genome (Kryukov et al., 2003). Selenoproteins have a number of functions, comprising various catalytic roles (glutathione peroxidases, thioredoxin reductases, and iodothyronine deiodinases), structural roles, and storage and transport activities. Selenium is present in foods mainly as selenomethionine and selenocysteine. It is absorbed efficiently by the intestine over a wide range of concentrations and across a variety of different molecular forms (Bates, 2005).

A total of 15 references were provided for the scientific substantiation of the claim. Ten human studies assessed plasma selenium concentrations in patients with rheumatoid arthritis, (juvenile) chronic polyarthritis, psoriatic arthritis, or in patients with elevated C-reactive protein, lung cancer or

adult T-cell leukaemia. Five human intervention studies have been provided which were carried out in patients with rheumatoid arthritis or chronic polyarthritis. The Panel considers that the evidence provided does not establish that patients with arthritis of different origin are representative of the general population with regard to the status of joint tissue, or that results obtained in studies on subjects with arthritis of different origin relating to the treatment of symptoms of these diseases can be extrapolated to the maintenance of normal joints in the general population.
The Panel considers that no conclusions can be drawn from these references for the scientific substantiation of the claimed effect.
The Panel concludes that a cause and effect relationship has not been established between the dietary intake of selenium and maintenance of normal joints.
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 selenium as per Annex to Regulation (EC) No 1924/2006. Such amounts can be easily consumed as part of a balanced diet. The target population is the general population. Tolerable Upper Intake Levels (ULs) have been established for adults, pregnant and lactating woman, children and adolescents (SCF, 2000).
