Whey proteins, or whey, are widely used and not only by those who play sports, to supplement the daily diet of complete and high biological value proteins . In fact, whey proteins have two enormous advantages: the first is that in the list of proteins with greater biological value, whey proteins occupy the first place according to their digestibility value (PDCAAS) and the former according to their biological value or BV; the second is that compared to casein proteins (speaking of the same food, ie milk supplements), whey proteins are digested faster , and are therefore perfect for recovery after sports.
Those who use whey know that there are many types on the market: concentrated, isolated, isolated and ion-exchange, microfiltered isolated, hydrolyzed whey. Isolated wheys are generally better than concentrated wheys. However, not enough research has been done on some of these products to be considered safe for health.

In fact, what is not talked about enough is the big chapter of the disadvantages of whey proteins in general on health : whey proteins are in fact insulinotropic, and many whey-based preparations, as well as in general many protein preparations for the food supplement, have acesulfame, aspartame or other sweeteners, natural or not, to make the taste more pleasant. Zero calorie sugars, whether natural or artificial, are still responsible for an increase in insulin and are related to the risk of metabolic syndrome and insulin resistance, just as are foods that cause insulin spikes.. And if the whey have various flavors (vanilla, chocolate), we add to the list the aromas, often artificial, which certainly do not improve the healthiness of the product. However, one study established that in a meal with a carbohydrate intake (whose carbohydrates were high glycemic indexes), the consumption of whey protein during the meal had a hypoglycemic effect. Normally, however, whey is consumed alone , often dissolved in water or worse in milk, and between meals. The effect isn’t quite ideal if you’re trying to burn fat as well. (
