In today's Chinese recipes, meat, eggs and milk are no longer expensive, because because of them, Chinese people grow taller, run faster, and have stronger muscles!
But thirty years in Hedong and thirty years in Hexi, we have just benefited from this, and their shortcomings have begun to be exposed little by little!
Unhealthy meat, eggs and milk that hurt the body
Is meat, eggs, and milk still unhealthy? Yes, the following meat, eggs and milk are unhealthy in their own way!
1
Carcinogenic processed meat
Heme iron in processed meat is a double-edged sword, which can promote metabolism in moderate amounts, but because the absorption efficiency of this substance in the body is too high, it is easy to ingest too much, resulting in DNA damage and inducing gene mutations.
Therefore, sausages, bacon, bacon, ham, etc., have all been included in the "List of Carcinogens" by the World Health Organization. At the same time, nitrates, nitrites, etc., added during processing, are also carcinogens.
2
Undercooked eggs
Raw eggs contain protease inhibitors, which will directly affect the absorption of protein, eating raw eggs, the absorption of protein is only 55%, while boiled eggs are as high as 91%.
Boiled half-boiled soft-boiled eggs, due to insufficient heating and insufficient cooking time, the protein structure is not completely hydrolyzed, but it is not easy to absorb. At the same time, it may also be infected with salmonella, which can cause diarrhea, vomiting and other toxic reactions.
3
Pretend to be nutritious milk
The ingredients of milk-containing beverages on the market are mainly water, sugar, a small amount of milk, as well as food additives such as pigments, flavors, thickeners, etc., and their protein and calcium content are far less than that of pure milk.
The sugar in the ingredients of this type of drink is also different from the lactose in milk, which is mostly free sucrose, which has little health benefit except for good taste.
How to consume meat, eggs and milk scientifically
Meat, eggs and milk are the "engineers" of human health, and their rich proteins participate in the synthesis of antibodies, digestive enzymes, muscles, and hormones, and also undertake the work of repairing tissues, regulating physiological functions, and maintaining immunity.
If you want to eat good meat, eggs and milk, the key is the following:
"Meat and vegetarian" matching
Depending on the source, there are also "meat and vegetarian" proteins. Plant-derived protein, free of cholesterol and saturated fat, and rich in dietary fiber, can be paired with animal protein, just to complement each other's strengths.
The plant protein that can be obtained in life is mainly beans, soy products, etc. It is recommended that you pair two taels of lean meat with two taels of tofu every day, of which the lean meat is mainly chicken, duck, fish and shrimp, plus a glass of milk and an egg, which is basically enough.
Drink less strong tea and fruits with high tannin acid after meals
A cup of tea after a meal is better than a good medicine. But in fact, there are not only tea polyphenols that promote digestion, but also a large amount of tannic acid, oxalic acid, etc., under the action of gastric acid, it will combine with the protein in the food to form an indigestible precipitate, on the other hand, they will also react with iron, calcium, magnesium and other metal elements in the food, increasing the risk of stones.
Similarly, fruits with a high tannin content, such as persimmons, black dates, hawthorns, pomegranates, etc., can also affect protein absorption.
Different groups of people have different needs
Sick people, as needed
1
People who are obese and have three highs
Leucine and methionine in proteins, the former has the risk of inducing atherosclerosis, and the latter is an independent factor in increasing cardiovascular disease.
Therefore, obese people with three highs should tend to low-fat protein when choosing protein foods, such as soybeans, fish, shrimp, eggs, milk, etc., and consume them as needed.
2
People with liver and kidney insufficiency
Nitrogenous substances such as ammonia, urea, and creatinine produced by protein decomposition need to be metabolized by the liver and kidneys, and long-term high-protein diet is likely to cause liver and kidney damage.
In particular, people with liver and kidney insufficiency need to limit the amount appropriately according to the degree of organ damage under the guidance of a doctor.
3
People with gastrointestinal diseases
The human intestine is an "omnivorous organ", not only relying on a single food to fill the body, high-protein eating habits, not only increase the burden on the stomach and intestines, the harmful bacteria and a large number of toxins produced after corruption, but also affect the growth of beneficial bacteria in the intestines, and destroy the balance of gastrointestinal flora.
At the same time, if you eat more protein, the dietary fiber will be reduced, and the dysbiosis will be more serious.
04
People with osteoporosis
Adequate protein is the "umbrella" for bone health, which can reduce the risk of osteoarthritis and fractures, maintain the stability and range of motion of the knee joint, prevent cartilage wear and tear, and protect the knee joint.
However, when there is too much protein, the blood will be too acidic, and the body will use bone calcium to neutralize the acidic substances, which will cause the loss of calcium.
Special populations, appropriate increments
Children and adolescents who are growing up, pregnant and lactating women, elderly people with weak digestive ability, patients with poor immunity or just after surgery, can appropriately increase protein intake;
The "Dietary Nutrient Reference Intake for Chinese Residents" recommends that at the age of 65, the daily protein intake of men is 65g/day, and that of women is 55g/day, while the elderly over 65 years old consume 7g more for both men and women.
Seeing this, do you know how to eat "meat, eggs and milk" healthily?
