Know Your Protein Requirements By Knowing Your Nitrogen Losses

Not many people know that… your protein requirements are most accurately gauged via your nitrogen losses. Nitrogen losses occur as a result of stress which might include resistance work such as weight lifting, abrasions or cuts, infections and worse still, sepsis, major trauma or burns. Needless to say we do not wish this on anybody, but fact remains that stress increases your protein (Nitrogen) requirements.

The most accurate way of determining protein requirements and indeed protein content of food is to establish nitrogen content and multiply it by a factor to arrive at total protein content. This single factor is 6.25, therefore should you require to estimate your protein requirements in nitrogen g/kg/day, then multiply a standard figure i.e. 0.17 (range of 0.14-0.20 for healthy individuals) by your weight in kg, and multiply by 6.25. This will give you a figure for somebody that is not metabolically active i.e. somebody that does not have a disease, infection or a drastically raised metabolic rate for whatever reason.

If you do have an infection etc then I urge you to contact your Doctor and ask for expert advice when estimating your nutritional requirements.
