- Protein sources have a high nitrogen level. Nitrogen is broken down in the liver and a biproduct of that process is is ammonia. Ammonia is poisonous and can be harmful to cells in the body.
- Stress on the kidneys can occur when the body has to process more than 2g of protein per kg of ideal body weight. (Which translates to 122g for my body.)
- High protein levels can decrease Vitamin B6 levels and cause deficiency.
- Increased calcium excretion has been associated with high intakes of protein from animal sources - leading to osteoporosis.
- Excess protein is converted to blood glucose in the body. Excess blood glucose is stored as fat. (Remember that the body also gets blood glucose from any carbs we eat, which is plenty of fuel for the body.)
But what about all the extra exercise I'm doing?
Studies have shown that professional athletes who do extreme strength training need only about a 50% increase in their protein intake. So for a 150lb man who is an avid body builder his normal need would be 54g of protein intake per day. Increase that by 50% and he'd only need 81g of protein.
Yeah, yeah, yeah.... that's not what THEY will tell you or what they even want to hear. They will say they need "1g of protein pre pound of current body weight." But I ask them to please check out that list I just wrote above about the risk factors for taking in excess protein. I really don't want to enter myself into that huge fight... so that's all I'm saying on that topic. LOL!
So there you go.... more information about protein then you ever wanted to know.
