Today, a netizen consulted on the consultation platform: saying that potatoes and apples are juiced to drink can prevent cancer? And claimed that a cancer patient on Kuaishou had been drinking for more than ten years and was well. It can be clearly said that there is no scientific basis for these two things to be put together to juice can fight cancer and prevent cancer. Not only these foods, it should be said that there is no single food in the world with specific and clear anti-cancer and anti-cancer effects. Cancer cells that can't be killed even by chemotherapy drugs with such a large toxicity, mutated cells that can't even be recognized by powerful immune cells, and want to destroy it through some kind of food, do you think it is possible?
You can often see articles with various such titles on the Internet, such as "Super Anti-Cancer Food List", "Top Ten Anti-Cancer Food" and so on. Bo people's eyeballs, but also let many people believe in it. Carefully study these foods, there are only a few categories:
1. Certain nutrients of these foods are believed to reduce the risk of tumorigenesis, such as deep-sea fish rich in n-3 polyunsaturated fatty acids, including salmon, tuna, etc. Therefore, tuna, salmon, etc. are considered super anti-cancer foods;
2. Vegetables and fruits are rich in natural plant compounds, such as resveratrol, sulforaphane, soybean isoflavones, lycopene, zeaxanthin, allicin, etc., so the corresponding foods rich in these natural compounds, such as grapes (seeds), cauliflower, beans, tomatoes, garlic, etc. are considered to have anti-cancer effects.
3. Whole grain foods, which are rich in dietary fiber, and dietary fiber is considered to have a reduced risk of bowel cancer in some studies, so it is considered an anti-cancer food.
4. Some expensive and rare health foods, such as saffron, cordyceps, ganoderma lucidum, ginseng, bird's nest, sea cucumber, dendrobium, etc., are also extracts that contain certain anti-cancer ingredients, or have ingredients that improve immunity.
These online articles tend to be generalized because certain nutrients or natural compounds have been confirmed by cell and animal tests to have anti-tumor effects, and these foods are inferred to be "super anti-cancer foods." You know, from in vitro cell tests, animal experiments to clinical trials, the distance is 108,000 miles. Without a clinical evidence-based medical basis, it cannot be said that this kind of thing is truly anti-cancer and anti-cancer. In fact, the occurrence of tumors is multifactorial, including influencing factors from genes, environment, food, psychology and other aspects. Preventing cancer through a certain food alone is obviously unreliable.
Under other equivalent conditions, a healthy and balanced diet certainly reduces the risk of developing certain tumors, that is, the likelihood of malignancy is reduced, but it is usually not achieved through a single food. Because different foods may have different nutrients that reduce tumor risk. Therefore, in the usual diet, as far as possible to ensure that the food is diversified and nutritionally balanced.
In addition, it is equally important to avoid some dietary patterns that increase the risk of tumor development, such as restricting sugary drinks, reducing high-energy foods (such as fried barbecue foods), reducing eating out, not overeating, etc., and maintaining a reasonable weight, all of which can help reduce the risk of tumorigenesis. At the same time, the increase of plant foods (whole grains, vegetables, fruits, nuts), restrictions on alcoholic beverages, daily moderate exercise and other comprehensive healthy lifestyle, is the best choice for cancer prevention and anti-cancer, only superstitious single "super cancer food" and only eat this food, but may lead to the lack of certain nutrients.
