Slightly more scientifically, we can measure our protein intakes according to the levels and type of activity that we do - in terms
of an amount for each kilogramme that we weigh.
Sedantary People - 0.75g / kg
Endurance Athletes - 1.2 - 1.4g / kg
Power Athletes - 1.6 - 1.8g / kg
This equates to about 80g for a 60kg distance runner and about 140g for an 80kg sprinter.
As mentionned earlier, this may well be covered by your normal diet - it is worth recording what you eat for a couple of days
to see what you intake is and then adjust it if necessary.
In particular, vegetarians and vegans should analyse their protein intake as it is likely to be lower than that of meat eaters.
Foods containing good quantities of protein include
Fish / Lean Meat / Poultry / Beans / Nuts / Eggs / Cheese
