What is Protein?
Protein is a vital nutrient that your body needs every day. Protein helps you maintain and rebuild your muscles after exercise. Foods high in protein include whey, fish, chicken, eggs, dairy produce (such as milk, cheese and yoghurt), beef and soya.
Proteins do most of the work your cells require for their structure and function. Protein is constantly turned over in the body and ideally losses should equal intake. Activity increases your need for protein, as it accelerates these losses.
How much protein do I need?
The UK Food Standards Agency recommends that adults take in around 55 grams of protein per day or 0.8g per kg of body weight. Guidelines for active individuals, however, such as that supplied by the American College of Sports Medicine (ACSM) or English Institute of Sport (EIS) recommend between 1 and 2 grams per kg a person weighs.

What are the best sources of protein and is whey protein really the best?
As far as your body is concerned, there are two different types of amino acids: essential and non-essential. Non-essential amino acids are amino acids that your body can create by itself. Essential amino acids cannot be created, and therefore the only way to get them is through food. Only a few foods provide the complete set of essential amino acids, and whey is one of them. The advantage with whey is that it has a great biological value – in other words, the body absorbs it faster. Figure 1 shows you a list of protein sources and their BV. A typical serving of whey contains the same amount of protein found in a chicken breast, but can also be low in both fat and carbohydrate.
What should I look for in a protein shake?

Check it for the informed sport logo to give reassurance that your product has been screened against the banned list of substances and that it comes from a reputable company with stringent quality control.
