Not many people know much about whey. Everyone knows it exists but only a few people know what it is used for and why it is good for you.
First and foremost, whey has purifying and detoxifying properties, it is easily digestible and it helps keep the gut healthy. It is suffice to say that whey protein has such a high biological value that it exceeds the nutritional value of protein of meat and vegetables.
Whey contains vitamins, calcium, potassium, lactose and mineral salts – a concentration of substances that our body needs. It does not contain casein and fat and for this reason is easily digestible. It passes through the stomach with ease and is beneficial to the gut.
How exactly is whey produced? It is a by-product of cheesemaking and is formed after rennet has been added and the milk, casein and fat have thickened. It contains many essential amino acids.
Whey also contains sugar. In the human body sugar is broken down into glucose, which is the ‘fuel’ that gives our bodies immediate energy, and galactose, which allows for adequate nourishment over the course of time. Whey also regulates the digestive process and improves and helps treat constipation. Furthermore, Lactic Acid stimulates the regeneration of intestinal flora.
Still with regard to the nutritional values of whey, its high energy value should be mentioned; it corresponds to 27 kilocalories (kcal) per 100 grammes of product. It is made up of carbohydrates (5.14 grammes), sugars (5.14 grammes), protein (0.85 grammes) and fat (0.36 grammes). It also contains a lot of sodium – roughly 54 mg – as well as water (93.12 grammes). As far as important minerals are concerned, it contains calcium, phosphorus and potassium.
