In the US we consume a large amount of protein on a daily basis, and ever since the Atkins craze people seem to be more concerned then ever about getting their protein. We should be aware however that protein has its own drawbacks.
• First, all animal forms of protein, even lean cuts, contain saturated fat.
• Second, if we eat more protein than our body needs in one day, the surplus will be converted and stored as fat.
• Third, proteins produce ammonium by-products, which must be eliminated by the body. This fact is two fold: one, the metabolism of the protein and the ammonium groups place an unnecessary burden on the liver and kidneys; two, the removal of the ammonium in the urine results in loss of water and electrolytes, leading to dehydration.
• Four, proteins increase the acidity of the blood and in order for the body to counter-balance this process it pulls calcium out of the bones and moves it into the blood as a buffer. This potentially weakens your bones.
• Last, but certainly not least, excess protein can lead to an increase in Homocysteine levels in the blood which is associated with development and progression of atherosclerosis (clogging of arteries).
So is protein bad? Definitely not, please eat your protein your body needs it to repair damaged tissue, replace old tissue and build functioning proteins in the body including muscle. Just be aware of how much protein you are consuming. Everything is in moderation.
How much protien should you eat?
• The average person, with very light physical activity, should eat 0.8-1.0 grams of protein per kg of body weight (divide pounds by 2.2 to convert to kg) per day.
• Moderately active persons exercising 30-45 minutes per day should be consuming 1.2 g/kg/day.
• Tri-athletes and marathon runners should be eating 1.6 grams per kilogram.
Example: An individual weighing 150 pounds, would be 68 kg and should consume 54-68 grams of protein per day. [(150/2.2) x (0.8)] – [(150/2.2) x (1.0)] = 54-68 grams
The key to remember is that when starting a new workout routine, whether for the first time or changing up an old one, you should increase your protien intake. Once you have settled into the new routine, after 3-4 weeks, you can bring the protien intake back down again.
Here are some examples of protein for you to consider:
• Half of an average skinless, boneless chicken breast is about 118 grams, and contains 27 grams protein and 130 calories,
• Half a salmon filet is about 198 grams and contains 43 grams protein and 289 calories.
• One cup of cooked black beans is about 172 grams and contains 15 grams protein and 227 calories.
