1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is phenylalanine.
L-phenylalanine is an essential amino acid and can be measured in food by established methods. It occurs naturally in foods, particularly protein-rich foods such as meat, fish and dairy products as a constituent of the proteins.
The Panel considers that the food constituent, L-phenylalanine, which is the subject of the health claims, is sufficiently characterised.
2.1. Zwiększenie czujności (ID 708, 1629)
The claimed effect is “mental health”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings, the Panel assumes that the claim refers to alertness which is a well defined construct and can be measured by validated psychometric cognitive tests.
The Panel considers that increased alertness might be a beneficial physiological effect.
3.1. Zwiększenie czujności (ID 708, 1629)
A total of 29 references were provided to substantiate the claimed effect, including seven textbooks, seven narrative reviews and four unclassified references which included a newsletter and a monograph. The Panel notes that these references did not provide any scientific data that could be used to substantiate the claimed effect.
The remaining 11 references described ten human studies and one animal study. Six of the human studies considered outcomes related to depression symptoms rather than alertness, three did not address the food constituent that is the subject of the claim, and the remaining reference described a study on patients with schizophrenia. No evidence was presented to show that findings from patients with schizophrenia can be extrapolated to the general population. The animal study investigated the oxidation of tryptophan to 5-hydroxytryptophan (5-HTP). 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 L-phenylalanine and increased alertness.
