Beef is one of the meat foods that people love to eat in daily life. It contains very rich nutrients, which can meet basic needs and help strengthen the body. But some people think that beef belongs to “red meat”, and red meat is listed as a 2A carcinogen, so eating beef will damage your health.

Beef is rich in protein, fat, vitamin B complex, niacin, calcium, iron, phosphorus elements, potassium, zinc, niacin, cholesterol, riboflavin, vitamin A, vitamin E, fat and other nutrients.

First let’s understand: the benefits of beef

1. Beef is rich in sarcosine

Beef contains more sarcosine than any other food, making it especially effective for building muscle and building strength. In the first few seconds of training, sarcosine is the source of muscle fuel, it can effectively supplement adenosine triphosphate, so that the training can last longer.

2. Beef contains vitamin B6< /p>

The greater the protein requirement, the more vitamin B6 should be added to the diet. Beef contains enough vitamin B6, which can help you strengthen your immune system, promote protein metabolism and synthesis, and help your body recover after intense training.

3. Beef Contains carnitine

The content of carnitine and sarcosine in chicken and fish is very high Low, but the content of beef is high. Carnitine is mainly used to support the metabolism of fat and produce branched chain amino acids, which is an amino acid that plays an important role in muscle growth of bodybuilders.

4. Beef contains potassium and protein

Potassium is a mineral that most athletes lack in their diets. Low potassium levels can inhibit protein synthesis and growth hormone production, thereby affecting muscle growth. Beef is rich in protein: 4 ounces of lean tenderloin yields 22 grams of first-rate protein.

5. Beef It is a low-fat source of linoleic acid

Beef is low in fat but rich in Containing bound linoleic acid, these potent antioxidants are effective in combating tissue damage during exercise such as weightlifting. Plus, linoleic acid acts as an antioxidant to maintain muscle mass.

6. Beef contains zinc and magnesium

Zinc is another antioxidant that helps synthesize protein and promote muscle growth. Zinc works with glutamate and vitamin B6 to boost the immune system. Magnesium supports protein synthesis, increases muscle strength, and more importantly increases the efficiency of insulin anabolism.

< span>Iron is an essential mineral for blood production. In contrast to the poor iron content in chicken, fish, and turkey, beef is rich in iron.

8. Beef contains alanine

Alanine works by producing sugar from the protein in your diet. If you don’t get enough carbohydrates, Alanine will supply your muscles with the energy they need to offset the deficit, allowing you to keep training The biggest benefit of this amino acid is that it can liberate muscles from the burden of energy supply.

Beef, is it “delicious in the world” or a “health killer”? After reading it, you will gain knowledge

But some people think that since beef is added to 2A category Carcinogens are bound to cause certain damage to the body. The carcinogenicity of beef stems from an animal experiment, a study from the University of California, which found that eating a lot of red meat and cheese can increase the risk of cancer, especially colorectal cancer.

Eating too much meat may increase physical discomfort. Beef has long been listed as red meat. Eating red meat for a long time will cause inflammation in the body. If it does not get better for a long time, it will increase the risk of malignant tumors.

Meats such as beef and mutton are reddish in color and brown when cooked Chicken and fish Other meats, whether raw or cooked, are white, so they are called white meat.

The study found that red meat So the redness is because it contains myoglobin, which has a relatively high content of ferrous ions, and this type of meat will naturally appear red.

With the deepening of research, it was found that there are three different forms of myoglobin, namely oxygenated hemoglobin (bright red color), myoglobin (red), metmyoglobin (brown).

Cut the beef and cut it, the meat on the outside is bright red and the meat on the inside is purple, many friends think This is an abnormality in the beef. In fact, the outer layer of the beef becomes bright red oxymyoglobin in contact with the air, and the meat inside is still purple-red myoglobin.

Class 2A carcinogen It mainly refers to the carcinogenicity of animals. The evidence is sufficient, but the evidence for human carcinogenicity is not sufficient. Simply put, the carcinogenic effect of red meat is not yet fully convinced. It can only be said that it is likely to increase the risk of cancer.

The current WHO classification of carcinogens is mainly based on the possibility of carcinogenicity and the degree of carcinogenicity The risk is small, and many people find it strange. For example, aflatoxin and processed meat are both first-class carcinogens, but only a small amount of exposure to aflatoxin can cause cancer, and long-term intake of processed meat can cause cancer risk .

The mechanism of carcinogenicity of red meat is not particularly clear, and there has been controversy. As long as you control the intake of beef, it will not increase the risk of cancer in the body. Beef is a food with high nutritional value. We have introduced it in detail above. Therefore, eating beef reasonably is more conducive to physical fitness.

But it does not mean that the more red meat intake The more the better, the daily amount should be controlled at 50-75 grams. If you like to eat beef, you should control the amount. When cooking beef, it is best to use steaming and stewing to retain a large amount of nutrients in beef. Eating roast beef will release carcinogens, heterocyclic amines and polycyclic aromatic pathways, which are not good for health.

What are the taboos for eating beef?

1. Food taboos

Beef is a commonly eaten meat, which can be supplemented Nutrient elements for the human body to replenish energy, such as eating a lot of beef, will easily lead to food accumulation, inability to digest quickly, and symptoms of indigestion such as abdominal pain and bloating. If it is combined with other indigestible foods, such as chestnuts, sweet potatoes, potatoes, corn, etc. , easy to aggravate indigestion good symptoms.

Two , Drug contraindications

1. Levodopa: Levodopa is a drug used to treat For Parkinson’s syndrome drugs, a low-protein diet is required during the medication. Beef is a high-protein food. When high-protein food enters the gastrointestinal tract of the human body, it will produce a large amount of amino acids that hinder the absorption of levodopa in the intestine, which will easily lead to a decrease in the efficacy of the drug;

2. Aminophylline: Beef as a high-protein diet can increase the activity of drug enzymes and accelerate the metabolism of some drugs. Therefore, taking theophylline drugs, such as aminophylline, doxofylline, etc., should not eat high-protein foods such as beef at the same time, so as not to reduce the curative effect.

Three , Contraindications for people

1. Crowds with scabies, eczema and itching: Beef belongs to hair, hair Food refers to food that is easy to cause boils or certain symptoms to change. Therefore, people with infectious diseases, liver disease, kidney disease, cough, and asthma should eat beef carefully to avoid aggravating symptoms;

2. People with weak digestion: beef It belongs to crude fiber and is difficult to digest. Therefore, the elderly, children, and people with weak digestion should not eat more. To avoid symptoms of gastrointestinal discomfort.
