1.9. Ochrona przed patogenami pochwowymi przez zwiększenie ilości bakterii kwasu mlekowego i/lub zmniejszenie ilości potencjalnie patogennych bakterii i/lub drożdży (ID 946)
	
	
			The claimed effect is “urogenital tract/natural vaginal defence”. The Panel assumes that the target  population is the general female population.
From the clarifications provided by Member States, the Panel assumes that the claimed effect refers to  defence against vaginal pathogens by increasing the number of lactobacilli and/or decreasing  potentially pathogenic bacteria and/or yeasts.
Unlike any other anatomical site of the body, most vaginal vaults are dominated by one or more  species of Lactobacillus. In over 70 % of women, vaginal microbiota is dominated by lactobacilli  (> 50 %) (Ling et al., 2010; Ravel et al., 2011; Yamamoto et al., 2009). This microbiota is different  from the more complex gut microbiota, where lactobacilli represent less than 3 % of the bacterial  population (Franks et al., 1998; Lay et al., 2005; Sghir et al., 2000). The diagnosis of bacterial  vaginosis (BV) is currently based on Nugent score (microscopic examination of Gram stained smear  or vaginal discharge for bacteria and „clue‟ cells). Nugent scores are classified into normal (0-3,  lactobacilli are present, but not Gardnerella/Bacteroides or curved Gram-negative bacilli),  intermediate (4-6, colonisation by Bacteroides/Gardenella and curved Gram-variable rods  (Mobiluncus)), and BV (7-10, BV with domination of Gardnerella/Bacteroides or curved Gram- negative bacilli and absence of that lactobacilli).
The Panel considers that defence against vaginal pathogens by increasing the proportion of  lactobacilli and/or decreasing the proportion of potentially pathogenic bacteria and/or yeasts is a  beneficial physiological effect.
	
    
			
	
		
			
1.10. Usuwanie metali ciężkich (ID 1871)
	
	
			The claimed effect is “alginate binds heavy metals, stimulates mucin production and protects the  colon, N-acetylcysteine detoxifies and removes heavy metals, piperine increases the bioavailability of  n-acetylcysteine”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings and of the references provided, the Panel assumes that the  claimed effect refers to the elimination of heavy metals.
The Panel considers that elimination of heavy metals is a beneficial physiological effect.
	
    
			
	
		
			
1.11. Utrzymanie odporności przeciw patogenom w górnych drogach oddechowych, poprzez utrzymywanie prawidłowego stanu układu odpornościowego (ID 1910)
	
	
			The claimed effect is “immune system”. 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 the upper respiratory tract defence against  pathogens by maintaining immune defences.
The Panel considers that maintenance of the upper respiratory tract defence against pathogens by  maintaining immune defences is a beneficial physiological effect.

			The references provided in relation to these claims were textbooks or narrative reviews which did not  provide any original data which could be used for the scientific substantiation of the claim, or  reported on animal or in vitro studies which addressed the effects of the food(s)/food constituent(s)  on, e.g., spontaneous contractions of the jejunum, adhesion properties of Helicobacter pylori,  pharmacologically or stress-induced gastric ulcers, necrotising enterocolitis, intestinal inflammation.  One human intervention study which addressed the effects of the food(s)/food constituent(s) on the  treatment of Helicobacter pylori infection was also provided. The Panel considers that no conclusions  can be drawn from these references for the scientific substantiation of the claims.
No human studies which investigated the effects of the food(s)/food constituent(s) on measures of  gastro-intestinal discomfort were provided in relation to any of the claims evaluated in this section.
The Panel concludes that a cause and effect relationship has not been established between the  consumption of the food(s)/food constituent(s) which are the subject of the claims evaluated in this  section and reduction of gastro-intestinal discomfort.

References regarding the composition of some food(s)/food constituent(s) were also  provided. The Panel considers that no conclusions can be drawn from these references for the  scientific substantiation of the claims.
No human studies which investigated the effects of the food(s)/food constituent(s) on measures of  cognitive function were provided in relation to any of the claims evaluated in this section.
One in vitro study which assessed the effects of a food constituent on amyloid beta-peptide in  neuronal cell cultures was provided. The Panel considers that evidence provided in in vitro studies is  not sufficient to predict the occurrence of an effect of the consumption of the food(s)/food  constituent(s) on contribution to normal cognitive function in vivo in humans.
The Panel concludes that a cause and effect relationship has not been established between the  consumption of the food(s)/food constituent(s) which are the subject of the claims evaluated in this  section and contribution to normal cognitive function.
