1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is docosahexaenoic acid (DHA), which is a well characterised n-3 long-chain fatty acid that can be quantified in foods by established methods. The absorption of DHA is well documented. This evaluation applies to all sources of DHA in the specified amounts.
The Panel considers that the food constituent, DHA, which is the subject of the health claims is sufficiently characterised.
2.6. Utrzymanie prawidłowego wzroku (ID 627, 632, 743, 3149)
The claimed effects are “brain, eye and nerve development”, “visual health and function” and “eye health”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings and clarifications provided by Member States, the Panel assumes that the claimed effect refers to the maintenance of normal vision.
The Panel considers that maintenance of normal vision is a beneficial physiological effect.
3.5. Utrzymanie prawidłowego wzroku (ID 627, 632, 743, 3149)
Deficiency of alpha linolenic acid, the parent fatty acid of the longer chain n-3 polyunsaturated fatty acids, including DHA, results in adverse clinical symptoms including, neurological abnormalities and poor growth (IoM, 2005). Evidence for the essentiality of n-3 fatty acids in humans can be drawn from case reports of patients receiving parenteral nutrition with intravenous lipids devoid of such fatty acids. Biochemical changes of n-3 fatty acids deficiency include a decrease in plasma and tissue DHA concentrations. There is no accepted cut-off concentration of plasma or tissue DHA concentrations below which functions ascribed to n-3 fatty acids such as visual or neurological functions are impaired (IoM, 2005). DHA is the major structural lipid in brain tissue and the central nervous system and the membrane lipids of brain grey matter and the retina contain very high concentrations of DHA. Biophysical and biochemical properties of DHA affect photoreceptor membrane function by altering permeability, fluidity, thickness, and lipid phase properties (Carlson et al., 1997).
The Panel notes that there is a well established role of DHA in retinal function.
The Panel concludes that a cause and effect relationship has been established between the consumption of DHA and the maintenance of normal vision.
4.3. Utrzymanie prawidłowego wzroku (ID 627, 632, 743, 3149)
The Panel considers that the following wording reflects the scientific evidence: “DHA contributes to the maintenance of normal vision.”
5.3. Utrzymanie prawidłowego wzroku (ID 627, 632,743, 3149)
The Panel considers that, in order to bear the claim, foods should contain 250 mg of DHA in one or more servings. Such amounts can be consumed as part of a balanced diet. The target population is the general population.
