Protein– Health Risks Associated with High Intake

There are many misconceptions about protein in the diet, e.g. more is better, or a high protein diet is essential for muscle building.  Neither of these is true. The only thing that causes muscles to grow is a well designed strength training programme, commitment and hard work.  Getting the diet right is, of course,  important for achieving goals in any sporting activity.

Protein consumed over and above the body’s requirements is converted to carbohydrate or fat by a process which is harmful to the liver and kidneys and can cause a compromise in fluid balance.  If meat is eaten several times a day over a period of several days a state of acidity will occur in the body.  The body will then attempt to neutralize this acidity by taking calcium and other mineral salts from the skeletal system.  Once the blood reserves are used up the calcium is then actually taken from the bones which can lead to bone density loss.  Moreover, any excess calcium may be dumped in inappropriate locations such as the arteries and joints leading to cardiovascular disease and arthritis. Low consumption of carbohydrates (simple and complex) and high protein intake can also result in the body taking its’ energy from the muscle leading to loss of lean tissue.
