Well, when it comes to the question of “what to eat”, it is so important for Chinese people that I am asked no less than 10 times a day in the clinic what to eat and what not to eat when I have a bladder tumor. What to eat is a daily question, but it is a very complicated one, which involves nutrition, tumor chemoprevention and environmental issues, all of which are enough to make a PhD graduate. In fact, in terms of real tumor prevention, the most serious problem we are facing now is the environment. Haze in the atmosphere, surface water pollution, enrichment of chemicals and heavy metals in the soil, pesticide abuse and unsafe food additives, etc. are all causes of cancer. However, living in this land, many things cannot be avoided, therefore, I start with what we discuss to eat and can only set aside food safety issues and start from a nutritional perspective. I advise my own family and friends are to try to obtain green food, all the substances ingested today will affect your life tomorrow, and sometimes spend a few extra dollars, the future savings may be more than a hundred times. Cao Ming, Department of Urology, Shanghai Renji Hospital Okay, back to the topic. First of all, let’s make one thing clear, that is, whatever you eat cannot prevent the recurrence of bladder tumor. If anyone has discovered that eating a certain thing can prevent the recurrence of bladder tumor, it is definitely one of the greatest discoveries in urology in the 21st century, and it is sure to be evaluated as an academician in China, and maybe any European country will issue a knighthood to him. Therefore, if you read my popular science article and want to say something about someone saying that eating something or other can prevent tumor recurrence, it is absolutely possible that I will be kicked out of the clinic. The second point is that human digestive organs are very powerful, and all food will be broken down into basic nutrients eventually. The problem is that the celery is a good choice. The other thing is that we are living in an era of information explosion, TV and radio stations and small advertisements, all kinds of anti-cancer information are spreading, in fact, 95% of this information is blackmail, which is the root cause of my writing these scientific articles. Please allow me to introduce you how to match various nutritional elements to reduce the probability of tumor occurrence in human body, instead of introducing you an anti-cancer recipe (by the way, there are many anti-cancer recipes, after knowing the relationship between your gastrointestinal function and nutritional elements, you can always spend some time to get an anti-cancer recipe by yourself). The next content will be of interest to not only tumor patients, but also to ladies, because a lot of data shows that people with high energy diet structure (also understandable as overweight people) are at high risk of tumor. High energy diet includes refined staple food, high cholesterol diet, high sugar diet, high fat diet, etc. This is all quite complicated, simply put, it is not recommended to eat fatty meat, less beef and mutton (red meat), less fried food, less sweet drinks, less wine, more coarse grains, and try to choose aquatic products or poultry and egg food for fat protein intake. Then, try to reduce the intake of synthetic foods, reduce the intake of pickled foods, reduce the intake of food additives, simply put, it is best to eat your own hands burn, really can not please go to the restaurant to order a few freshly fried small dishes, but also eat less potato chips, ice cream, beef jerky snacks, instant noodles, frozen food, semi-finished food, canned food are not very healthy. Adequate dietary fiber intake as well as vitamin intake is very important, is to ensure a certain daily intake of fresh fruits and vegetables, if the limit to eat full, can eat vegetables to eat less meat it. The point here is that all nutritional intake is related to the person’s own weight, height and basal metabolic rate, if there is a risk of tumor, then reducing energy intake is generally beneficial (that is, eating less than before the disease will be beneficial, so we only compare with their own past, do not compare with others, it is meaningless. (Of course, if you are very thin and thin is another story). Here is another issue is the basal metabolic rate, simply put, is your muscle content, muscle accounted for the higher weight general basal metabolic rate is also higher, in the case of high basal metabolic rate can be appropriate to relax the caloric intake. If you eat a piece of fat today, you can consider going for a 20-minute jog in the evening. Well, I am not a dieter, I myself am in a situation of obesity, what I said above is not fooling you, these contents are the conclusions of the most authoritative tumor database in the United States after years of follow-up. It is that, although I am not very healthy myself, I still want everyone to be healthy (which is really, I am moved by myself). Some things still need to be discussed separately, the first is that seafood is a good thing, it is absolutely not carcinogenic. From a worldwide perspective some countries that use seafood as the main animal protein intake have relatively low tumor rates; from a nutritional point of view most seafood is high in protein and low in fat, the fat is also a high percentage of unsaturated fatty acids, it will definitely be better than eating beef and lamb; from an environmental point of view, seafood is definitely better contaminated by chemicals than on land. So which person is always saying to you that tumor patients can’t eat seafood, don’t bother him in the future. Secondly, chicken can be eaten, eggs can also be eaten, provided that the chicken does not eat any hormones, antibiotics or anything (but in fact, if the chicken eats hormones, the pig is also eating). Because the fat content of chicken meat is very low, belongs to the white meat. The old saying, the same eat meat eat poultry and eggs than beef and lamb better. Well, I actually love beef I also love lamb, only they are indeed high-fat, low-fiber foods. The third, antioxidant food is beneficial, although they have not been proven to prevent tumors, but it does help, the antioxidants in food mainly from vitamins, vitamin A, C, E, etc. have a role, including cauliflower, carrots, grapes, onions and so on and so forth, in fact, onion, ginger and garlic are also good, these specific content we check it for ourselves. The fourth, the regulation of immunity food, honestly through food to regulate the body’s immunity, I personally doubt, but theoretically regardless of what kind of tumor, autoimmunity is not a bad thing, but through the digestive tract absorption to mobilize the immune system is actually not very reliable. The only thing I can recommend for this content is wormwood, which I have read the paper and have some understanding of, and allicin, which should help, but as for the rest, I can only say I am not sure. Well, what I want to say here is that I often hear my patient friends say that they can’t eat seafood, chicken, ginger, garlic, and even green vegetables when they have tumors, but here I would like to emphasize that all these things that can’t be eaten are the ones I recommend. Finally, I would like to list the individual choices recommended by the American College of Oncology in its guidelines on nutrition and exercise for cancer prevention. Achieve and maintain a healthy weight throughout your life. Ensure that you are as thin as possible without being underweight. Avoid weight gain at all ages; for those who are currently overweight or obese, losing even a small amount of weight will benefit health and will be a good start. Regular exercise and limiting the intake of high-energy foods and beverages are the keys to maintaining a healthy weight. Adopt an active lifestyle. Adults should ensure at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity exercise per week, or an equivalent combination of both, even better if spread evenly throughout the week. Children and adolescents should ensure at least one hour of moderate- or vigorous-intensity exercise per day and at least three days of vigorous-intensity physical activity per week. Limit sedentary behaviors such as sitting, lying down, watching television, or other forms of screen-facing entertainment. Doing some exercise outside of your regular activities, regardless of intensity, can provide many benefits to your body. Consume a healthy diet that emphasizes plant-based foods. Choose foods and beverages that are designed to obtain and maintain a healthy weight. Limit the consumption of meat and red meat. Consume at least 2.5 cups of fruits and vegetables per day. Choose whole grains over processed foods. Limit your alcohol consumption. No more than one serving of alcohol per day for women and no more than two servings of alcohol per day for men.
