We often hear that we should buy darker vegetables. Because dark vegetables have higher vitamins and dietary fiber, they are more beneficial to the body. Red vegetables contain high lycopene, orange vegetables contain more carotene, black vegetables contain more iron, and white vegetables are often ignored and ignored by people. In fact, white vegetables have a very important function: anti-cancer.
  White vegetables mainly include onion, garlic, cabbage, Chinese cabbage, cauliflower, white radish, etc.
   Onions and garlic are rich in organic sulfides, which can reduce blood lipids and prevent cardiovascular diseases. In addition, they are also rich in trace element selenium with anti-cancer effects. Selenium can accelerate the decomposition of peroxides in the body and play a role in inhibiting malignant tumors; selenium can also promote the production of glutathione and other substances in the human body, making cancer lose its “toxicity”. However, onions and garlic should not be consumed in excess. Excessive consumption will cause flatulence and excessive exhaust, which may cause discomfort.
   Cabbage, Chinese cabbage, cauliflower, and white radish are representatives of cruciferous vegetables. Their nutrient content is balanced, especially containing a glucosinolate active substance, which can be degraded into benzyl ethyl isothiocyanate, indole-3-acetonitrile and sulforaphane, etc., which has anti-cancer effects. The epidemiological survey also found that people who regularly consume cruciferous vegetables have a lower incidence of gastric cancer, esophageal cancer and lung cancer. There are many ways to eat cabbage vegetables, but be careful not to overcook them to ensure maximum retention of nutrients.
  茭白, rich in protein, fat, carbohydrates, vitamin b1, vitamin b2, vitamin e, carotene and minerals and other ingredients, the best quality in spring and summer. Traditional Chinese medicine believes that Zizania root has the effects of clearing dampness and heat, diuresis and quenching thirst, relieving alcohol and toxins, tonic and strengthening the body, but because it has more oxalic acid, its calcium is not easily absorbed by the human body. People who have more oxalate crystals in urine should not eat more. Zizania is suitable for cooking methods such as frying and roasting, or as ingredients and fillings.
  
  
   often look at the “clock” and “watch” to know the disease
   He Juncheng
  
  With age, the functions of the various systems of the human body will gradually decline to varying degrees. If you can always check the “clock” and “watch” on your body, you can take preventive measures.
  
  1  the inherent “biological clock” of the human body-biological rhythms
  Normal: I can wake up happily in the specified time every morning, do not doze off at work during the day, stay up at night, do not have nightmares, and fall asleep quickly after going to bed, etc.
   Abnormal: If a person changes his life rhythm for a long time, it will change the amount of hormone secretion in the body, leading to neurological disorders, and the body clock will inevitably be affected.
  
  2  The “barometer” of good health-appetite status
  Normal: If you don’t eat for a few hours, you will have “hunger”, as long as you eat something appropriately, you can relieve your hunger.
   abnormal: loss of appetite, eatingSudden decrease in volume.
  
  3  the “weathervane” of good health-weight change
  Normal: standard weight (kg) = height cm-105, if it exceeds 20% of the standard weight, it is obese. This algorithm is simple and suitable for self-assessment of the weight of the general population. When measuring weight, it is best to do it after defecation in the morning.
   Abnormal: Obesity and weight loss, especially sudden weight gain or loss in a short period of time.
  
  4  The “thermometer” of mental health, good or bad temper
  Normal: Peace of mind. A person lives in a fast-paced, high-efficiency, and heavy-duty environment, and his spirit is always under pressure. It’s normal to go home occasionally to lose your temper.
   abnormal: often loses temper for no reason. Generally speaking, high blood pressure, stomach problems, liver fire, etc. can cause people to be irritable and easily lose their temper.
  
  5  “Physical Examination Form” for gastrointestinal health-the color of stool
  Normal: Different quality of the diet, the stool will show different colors.
   Abnormal: The stool is mixed with blood, mucus or diarrhea is not stopped-gastrointestinal problems have occurred; stool is dark and thick like asphalt-gastrointestinal disease has caused bleeding; stool is white-possibly suffering from biliary tract disease. There is also urine. Normal people are light yellow and darker in the morning. Under normal circumstances, if the urine becomes muddy, it is abnormal. You should go to the hospital for examination.
