1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is gamma-linolenic acid (GLA).
GLA is a n-6 long-chain polyunsaturated fatty acid which is present in small amounts in a variety of foods of both plant and animal origin and which can also be synthesised in the human body from its precursor linoleic acid (LA). GLA is a well recognised nutrient and can be measured in foods by established methods. This evaluation applies to GLA from all sources.
The Panel considers that the food constituent, gamma-linolenic acid, which is the subject of the health claims is sufficiently characterised.
2.4. Utrzymanie prawidłowego ciśnienia tętniczego (ID 1771)
The claimed effect is “vascular health”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings, the Panel assumes that the claimed effect refers to maintenance of normal blood pressure and to maintenance of normal blood cholesterol concentrations. The latter will be assessed in section 2.5.
Blood pressure (BP) is the pressure (per unit area) exerted by circulating blood on the walls of blood
vessels. Elevated BP, by convention 140 mmHg (systolic) and/or 90 mmHg (diastolic), may compromise the normal function of the arteries.
The Panel considers that maintenance of normal blood pressure is a beneficial physiological effect.
2.5. Utrzymanie prawidłowego stężenia cholesterolu we krwi (ID 1771)
The claimed effect is “vascular health”. The Panel assumes that the target population is the general population.
In the context of the proposed wordings, the Panel assumes that the claimed effect refers to maintenance of normal blood pressure and to maintenance of normal blood cholesterol concentrations. The former has been assessed in section 2.4.
Low-density lipoproteins (LDL) carry cholesterol from the liver to peripheral tissues, including the arteries. Elevated LDL-cholesterol, by convention >160 mg/dL, may compromise the normal structure and function of the arteries.
The Panel considers that maintenance of normal blood cholesterol concentrations is a beneficial physiological effect.
3.4. Utrzymanie prawidłowego ciśnienia tętniczego (ID 1771)
No references in relation to this claim were provided on the effects of consumption of GLA on blood pressure.
The Panel concludes that a cause and effect relationship has not been established between the consumption of GLA and maintenance of normal blood pressure.
3.5. Utrzymanie prawidłowego stężenia cholesterolu we krwi (ID 1771)
No references in relation to this claim were provided on the effects of consumption of GLA on blood cholesterol.
The Panel concludes that a cause and effect relationship has not been established between the consumption of GLA and maintenance of normal blood cholesterol concentrations.
