The body doesn’t need high amount of protein PART 1
It is very interesting the study carried out on patients with proteinuria and renal failure, whose glomerular filtrate was only 50 ml / min. Through glomerular filtrate or glomerular clearance we understand the scrubber plasma volume in every minute by the two kidney glomeruli. Normally, the glomerular filtrate it’s about 125 ml / min. that a glomerular filtrate of 50 ml / min. means a kidney function loss of over 50%.
Wanting to see if evolution or progress of renal damage might stop, researchers have prescribed these patients who were losing protein through the urine, a diet with only 40 g protein per day. To the astonishment of many, it was found that after one year, kidney function was unchanged, the filtering capacity of the kidneys maintaining to 50 mL / min. What was unthinkable before was proved to be possible, the evolution of diabetic nephropathy could be stopped.
There remained a question without an answer: What influence has the reduction of protein intake on proteinuria, ie on blood protein quantity? Research has shown that the albumin or protein levels increased in a significant way despite low protein diets. Results were a sensation, because until then, doctors believed that a diabetic who loses protein through urine needs diet rich in protein. And how is possible to increase the protein in the blood, while the intake was reduced?
Determination of protein lost in the urine quantity at the beginning and the end of research, showed that after a year of low protein diet, urinary protein loss decreased a lot. From 2 g of daily protein loss, after one year there was a loss of only 100 mg, ie 20 times less. Diet low in protein resulted also a decrease in systolic and diastolic blood pressure.
In short, the hypoproteic diet in diabetics with renal failure had four effects: stopped the kidney insufficiency evolution, increased the albumin, decreased the blood pressure and proteinuria. Hopefully, at least in the diabetologia circle, the protein myth was buried forever.
Currently, the work is on revising the quantities of proteins considered necessary for human beings, amounts that vary depending on the age. If the proteins could be the equivalent of a car body, then we understand why, in the first 6 months of life it is considered that it takes 1.85 g of protein per kilogram of body weight per day.
Here are some values considered required:
6 – 9 months 1,65g per body kg
9 – 12 months 1,50g per body kg
1 – 2 years 1,20g per body kg
2 – 3 years 1,15g per body kg
3 – 5 years 1,10g per body kg
5 – 14 years 1g per body kg
14 – 16 years 0,92g per body kg
16 – 18 years 0,85g per body kg
Adults 0,75g per body kg
In fact, the protein requirements of adults are smaller. Knowing that in the first years of life, in the years of development, children require a larger protein amounts, parents, in particular mothers, believes that with more protein as they give, the more they will promote the health of their kids. It is the mistake that is repeated always – it’s much easier to give the child a slice of cheese, a bigger steak, money or toys, instead of giving your time, communicate and be the dearest comrades to your child. This is the mistakes that happens not only with sweets but also with proteins: children are simply stuffed. And this is said by the nutrition report for 2002, the German company of Nutrition draw attention on some mistakes in population alimentation, which should necessarily be corrected. Among other things, the report says: “Protein intake in children under age 10 have to be drastically decreased. Protein consumption, in this age group, exceeds twice the recommended values, and this has fatal consequences. Who consumes excessive amounts of animal protein, meat and sausages, not only automatically ingests more fat, which leads to obesity, but animal protein, as the caffeinated beverages, enhance the elimination of calcium through the kidneys. Thus, the little calcium available to the young body it’s wasted, without being used.
Attention, parents! Animal protein (not just meat but also cheese and eggs) lead to calcium loss and is recommended to lower the protein intake in children. Accustome the children, from the earliest age, to consume vegetables, legumes, fruits, grain, to eat carrots, kale and salads of all kinds.
In December 2001 in the german press, were published articles that warned against the consumption of meat and smoked sausage, just when these foods were requested the most.
Here are the arguments presented:
- First, meats smoked sausages are foods with the highest salt content: 100 gram containing 5 to 6 g of salt. And salt plays an important role in the occurrence of hypertension, gastric cancer and by the fact that causes a loss of calcium through the urine, the osteoporosis.
