Proteins – Meat proteins increase the cholesterol! PART 1

Liquids consumed during meals dilutes the enzymes concentration in the stomach, and if are very cold, drop the temperature at a level which enzymes can not work, and thereby delaying the protein digestion, which will be continued and done in the intestine.

Many still believe and are convinced that in order to get the necessary proteins, they need meat and eggs or, at least, dairy products. Sadder is the fact that this myth is told today to students on the Faculties of Medicine banks. Myths disappear very hard.

For millennia, the majority of the world population has maintained the existence using earth products: cereals, legumes, potatoes, vegetables and fruits. Except the times of Noah flood, no natural disaster managed to stop the mankind multiplying. It is true that in all times there was a small number of privileged people who could afford to consume meat too. 3,100 years ago, the reapers of Boaz ate roasted grains and soaked the piece of pita bread in a broth with vinegar.

In civilized countries, the meat consumption has spread only in the last 150 years.

In 1816, in Germany, the annual consumption of meat and sausage was 13.7 kg per person; in 1900, 47 kg; in 1975, 82.6 kg and 1993, 95.5 kg. This enormous growth was achieved mostly through pork, and in the last 25 years through poultry meat.

Proteins were described in 1838 by the swedish chemist and doctor Berzelius. By 1880, the german scientist Justus Liebig discovered that muscles are made of proteins and released the slogan: “Who wants to have muscles must consume many proteins”. Simultaneously, Carl Voit, a german doctor who worked with Liebig, returning to hometown, Munich, calculated the proteins intake to 1,000 miners who were working in mines around and found that they had a daily intake of about 120 g; this amount become “Voit’s standard for the proteins needed. “In 1912, the englishman McCay claimed  Voit’s finding, both recommending a daily intake of 100-150 g of protein for an adult.

The myth that who wants to have muscles has to eat meat was denounced already since 1913, when an american professor dr. Russell Chittenden, Yale University, USA, and swedish Hindhede said that 25-55 g of proteins per day are more than enough.

Chittenden conducted three studies on well trained athletes, omnivores, consuming more meat than ordinary people. After recording the performances, athletes were switched to a vegetarian diet for 5 months. When repeating the tests, was found that after the vegetarian diet, have improved the performance with 35%.

Modern scientific research shows that the real needs of the human body, in terms of proteins, are only about 30 g per day. Once the bodywork was finished, to operate, the car needs only a few spare parts, which are renewed from time to time.

Our body is very effective in recycle its own proteins. Under normal conditions, the only loss of protein to be replaced are those that the body can not recover: the hair, nails and cells from the blistered skin.

National Academy of Sciences of the United States recommends for an adult 0.7 g protein per weight kg, so 42-50 g for a person of 60-70 kg or about 10-12% of total caloric intake.
