1. Charakterystyka żywności / składnika

The food that is the subject of the health claim is maize oil.
Maize oil is a by-product of the milling of maize for the production of starch. The fatty acid composition of maize oil consists of about 56 % linoleic acid (LA), 29 % oleic acid and 13 % saturated fatty acids (SFAs).
The Panel considers that the food, maize oil, which is the subject of the health claim, is sufficiently characterised in relation to the claimed effect.

2. Znaczenie oświadczenia dla zdrowia człowieka

The claimed effect is “corn oil with a guaranteed polyunsaturated fatty acids content (56 % of total fatty acids), supplemented with vitamin E”. 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 LDL-cholesterol concentrations.
Low-density lipoproteins (LDL) carry cholesterol from the liver to peripheral tissues, including the arteries. Elevated LDL-cholesterol, by convention >160 mg/dL (>4.1 mmol/L), may compromise the normal structure and function of the arteries.
The Panel considers that maintenance of normal blood LDL-cholesterol concentrations is a beneficial physiological effect.

None of the references cited in the consolidated list specifically addressed the effects of maize oil on blood cholesterol concentrations.
Mensink et al. (2003) found in a meta-analysis of 60 controlled trials that replacing carbohydrates with SFAs in an amount representing 1 E% increased LDL-cholesterol concentrations by 0.032 mmol/L. Replacement with cis-monounsaturated fatty acids (cis-MUFAs) (i.e. oleic acid) reduced LDL-cholesterol concentrations by only 0.009 mmol/L. The corresponding reduction in LDL-cholesterol concentrations by cis-polyunsaturated fatty acids (cis-PUFAs) was significantly larger (i.e. 0.019 mmol/L).
Wardlaw et al. (1990) compared maize oil and high-oleic acid sunflower oil with butter in a randomised cross-over intervention study in 20 healthy men and found that maize oil reduced serum total cholesterol concentrations by 21 %, and that high-oleic acid sunflower oil reduced them by 16 %. In the study by Lichtenstein (1993) rapeseed oil (about 6 % SFAs, 60 % oleic acid, 20 % LA and 11 % alpha-linolenic acid), maize oil and olive oil (about 15 % SFAs, 70 % oleic acid and 11 % PUFAs (mainly LA)) as part of the National Cholesterol Education Program (NCEP) Step 2 diet were compared with the average US diet in a randomised cross-over study in 15 subjects. Both rapeseed oil (-12 %) and maize oil (-13 %) reduced serum total cholesterol concentrations significantly more than olive oil (-7 %). The Panel notes that the differences observed between oils with respect to their effects on blood cholesterol could be explained by their fatty acid composition.
No studies that investigated whether maize oil has a cholesterol-lowering effect beyond what could be expected from the fatty acid composition of maize oil have been provided.
The Panel concludes that a cause and effect relationship has not been established between the consumption of maize oil and maintenance of normal blood LDL-cholesterol concentrations beyond what could be expected from the fatty acid composition of maize oil.
A claim on the replacement of mixtures of SFAs with cis-MUFAs and/or cis-PUFAs in foods or diets and maintenance of normal blood LDL-cholesterol concentrations has already been assessed with a favourable outcome (EFSA Panel on Dietetic Products Nutrition and Allergies (NDA), 2011).
A claim on linoleic acid and maintenance of normal blood cholesterol concentrations has also already been assessed with a favourable outcome (EFSA Panel on Dietetic Products Nutrition and Allergies (NDA), 2009).
