Be wary of protein weight loss methods Excessive protein is harmful

The harm of too high protein

Excessive protein is the channel for toxins to enter the human body, which can destroy the structure of cells and disrupt the osmotic balance of liquid pressure inside and outside the cell membrane. Eventually it brings great harm to the body.

When balance is disturbed, water enters the cell, in addition to trying to restore balance, it also dilutes excess proteins in the cell. Dilution is a physiological response to excess matter in cells.

Adding water can restore osmotic balance, but it can also cause edema. In fact, the physiological proteins that form cell tissue are not the same as the animal proteins contained in hamburgers.

The protein we need is physiological protein, but the protein contained in foods such as hamburgers is not among them. In short, things will turn around when they reach extremes. Excessive intake of dietary protein will threaten the cardiovascular and cerebrovascular health of the human body and cause various chronic diseases.

Proteins are broken down locally in the gastrointestinal tract into Proteoses, pepetones, and polypeptides. Most protein decomposition takes place in the small intestine, and pancreatic enzymes further digest the protein into polypeptides and amino acids. Although protein can produce energy, in order to digest it, the body must consume more energy and process the acidic ash left behind by the protein.

In other words, protein is a source of negative energy that produces less energy than it consumes. Many weight-loss diet plans on the market have high-protein properties, perhaps using this principle.

Dietary protein takes more nutrients from the body than it can provide. In addition, dietary protein also leaves acidic ash. From this point of view, excessive intake of protein will not outweigh the gain.

Eating large amounts of protein will also increase the metabolic rate too quickly in a short period of time, exceeding the body's load, consuming a lot of energy, and causing serious damage to the body.

To make matters worse, this situation can last for 3 to 12 hours. The faster the metabolic rate, the faster energy is produced. This is why people who are accustomed to eating large amounts of protein feel listless and unmotivated once they stop consuming meat.

Obtaining energy from a large amount of protein is different from the energy of candy. The biggest difference is that protein requires a longer digestion time. In other words, protein takes longer to stimulate energy production.

Those who are nervous, fidgeting, grabbing the remote control and constantly changing channels are showing symptoms of excessive protein. They think they are full of energy, but in fact, they are just stimulated.

Among various stimulants, protein is second only to drugs. Compared with protein, coffee, tea, and cola are only children's specialties.

Caffeinated drinks are nowhere near as powerful as a steak. The former lasts only an hour, while the latter keeps you excited for hours. Once you understand the continuous stimulation effect of protein, I believe you won't naively think that you can still sleep peacefully after enjoying a high-protein dinner, will you? If your body is struggling to process the cheeseburger and milkshake you ate at 7 p.m., how can you get a complete rest at 2 a.m.?

If you can't sleep and eat cookies and peanut butter in the middle of the night, it's not surprising that you still wake up tired the next day.

You think you are resting, but in fact your body works all night long. Every day when you sleep, it is the time for your body to rebuild. If the body has to constantly process large amounts of protein, it will never be able to repair it, which will eventually lead to chronic disease.

Protein is composed of three major elements: carbon, oxygen, hydrogen, carbohydrates, amino acids, nitrogen, etc. Every amino acid contains nitrogen.

In the past, dietary protein requirements were determined based on nitrogen comparisons, which compared daily nitrogen intake with the nitrogen content in urine and feces. In this way, the recommended daily protein intake was reduced from 118 grams set at the end of the 19th century to 46 to 56 grams set in 1980.

In addition, Dr. Robert Brown pointed out that the recommended intake of protein should be reduced to 25 to 35 grams. As for my opinion, the recommended amount of protein should be reduced further.

Animal proteins contain nitrogen. Nitrogen is not a "bad guy". We need nitrogen, but it's just not much. The human body can eliminate the nitrogen contained in appropriate amounts of protein in the form of urea.

Neutral urea salts are formed in the liver and eliminated in urine. The more protein you eat, the more urea you have in your urine. Excessive protein can overload the urea manufacturing system, so the reserve system has to be mobilized at this time.

The kidneys and most cells produce ammonia strong bases, a waste of nitrogen. Ammonia combines with hydrogen ions in acidic ash food and replaces sodium as a neutralizing factor. However, it is a reserve system after all, and the body cannot rely on it for a long time.

The storage system that uses ammonia to process excess protein fully demonstrates the extremely precise structure of the human body: nitrogen is the waste produced by excess protein, but is eliminated in the form of ammonia and used to neutralize the acidity of excess protein. It's a seamless emergency system: it makes your urine pH as high as 7.5 or 8.0, which appears weakly alkaline. Although the alkalinity of urine is related to ammonia, the presence of ammonia is caused by excessive protein in the body. Alkaline urine containing ammonia means that your health is in danger!

Yan Jia excerpted from "Listen! PH speaks "When did we become so obsessed with protein? As if osteoporosis was not enough, it was later discovered that other diseases also resulted from the intake of excessive protein, especially animal protein. One of them was kidney stones.

Because we have to digest excess protein, the calcium lost from our bones must be discharged somewhere after it plays its role in the blood: the same is true for the calcium that we ingest but cannot be utilized and absorbed because the ratio of phosphorus and calcium is too high. This calcium is eventually discharged into the urine, causing the calcium content in the renal system to be high and often becoming crystalline stone.

This is why kidney stones, the most painful in emergency cases, occur at a much higher rate among meat eaters than among vegetarians.

In addition, there is a lot of evidence that excessive protein is related to the destruction of kidney fibers and the degradation of kidney function. Excess protein does not just flow out of the body slowly with urine. The kidneys must work hard to expel it.

Many experiments on animals have shown that the higher the protein in the diet, the greater the risk of kidney inflammation and swelling, and the more serious the condition. If humans consume too much protein, our kidneys will have the same problem.

People who have had kidney damage or lost one kidney can often use a diet that restricts protein content to ensure the function of the other kidney. If people with kidney problems do not restrict protein intake, especially those who continue to eat meat, their kidneys often quickly deteriorate to the point where they rely on kidney dialysis machines.

It is important and must be emphasized that the association between kidney disease and excess protein, like the association between osteoporosis and excess protein, is no longer just considered possible in the knowledgeable medical community. Too many researchers have done too many tests in too many different situations, and the results are so consistent that it is now confirmed.

Because of the growing evidence against ingesting too much protein, you may shake your head and wonder, how did we get so obsessed with protein?

Almost all early nutritional research raised animals because of human needs for meat and milk. The purpose of those studies was to produce the most animals in the shortest possible time. Therefore, the beginning of these studies contained rapid growth. The concept that "everyone wants to grow up to be big" led to nutritional research focusing on finding a diet that could achieve this goal.

Early experiments found that mice grew fastest when fed animal protein. This finding led to the hypothesis that animal protein was superior. Later experiments also proved that mice did grow faster when eating animal protein.

However, the mentality of "big is good" was hit by some other discoveries. They found that although mice grow up faster to eat meat, they also die earlier, and many diseases that vegetarian mice do not have can develop.

An article aptly titled "Rapid Growth-Shorter Life" was published in the Journal of the American Medical Association. The report said that a diet high in animal protein shortened the life span of several animals. These findings confirmed that world health statistics show that people who eat meat do not live longer than people who are vegetarian. They also found that meat eaters have a higher cancer rate than vegetarians. Exactly how excess protein is related to cancer is not yet understood, but there are growing signs that they are indeed related.
