1. Charakterystyka żywności / składnika
The food constituent that is the subject of the health claims is whey protein.
Whey protein is a mixture of globular proteins isolated from whey, a by-product obtained during the manufacturing of cheese from cow's milk. Beta-lactoglobulin (approx. 50 %), alpha-lactalbumin (approx 20 %), bovine serum albumin (approx 10 %) and immunoglobulins are the major protein fractions in whey.
Whey can be treated and processed in different ways depending on the type of whey protein end products to be obtained. Main commercial forms are concentrates (29-89 % protein by weight), isolates (about 90 % protein by weight) and hydrolysates (partially pre-digested). Small differences in composition between different whey protein products may exist depending on the manufacturing processes applied. These products generally have a high content of essential amino acids, especially high proportions of available lysine and cysteine.
A claim on protein and growth or maintenance of muscle mass has been assessed by the Panel with a favourable outcome (EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA), 2010). In this opinion, the Panel will address whether the consumption of whey protein has any effect on growth or maintenance of muscle mass over and above the well established role of protein on the claimed effect.
The Panel considers that the food constituent, whey protein, which is the subject of the health claims, is sufficiently characterised in relation to the claimed effects.
2.2. Udział w utrzymaniu lub osiągnięciu prawidłowej masy ciała (ID 1683)
The claimed effect is “weight management”. The Panel assumes that the target population is the general population.
Weight management can be interpreted as contribution to the maintenance of a normal body weight. In this context, weight loss in overweight individuals even without achieving a normal body weight is considered to be a beneficial physiological effect.
The Panel considers that contribution to the maintenance or achievement of a normal body weight is a beneficial physiological effect.
3.2. Udział w utrzymaniu lub osiągnięciu prawidłowej masy ciała (ID 1683)
The references provided included intervention studies and reviews on the effects of dietary protein in general, on the effects of dairy products and calcium on adiposity and weight management, and on whey protein specifically, but on outcomes other than measures of body weight (e.g. glucose homeostasis, appetite and food consumption). 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 consumption of whey protein and contribution to the maintenance or achievement of a normal body weight.
