Taro is a common food on our daily table, it has a sticky taste, sweet taste, rich in nutrition, rich in protein, calcium, phosphorus, magnesium, potassium, vitamin C, B vitamins, dietary fiber, carotene, polyphenols, polysaccharides and other nutrients, some people say that taro belongs to the staple food of potatoes, because its starch content is more than 20%;It is also said that taro is a root vegetable because of its high water content and the fact that it contains a variety of vitamins, which is obviously very different from various grain seeds. The "Dietary Guidelines for Chinese Residents" (2016 Edition) recommends that foods such as taro, potatoes, sweet potatoes and yams be included in the category of staple foods, and it is recommended to eat 50 100 grams a day to replace some rice and white flour with them, which is more nutritious and healthy.
Modern studies have found that taro contains saponins and polysaccharides, which have anti-inflammatory, anti-fatigue, anticoagulant, anti-thrombosis, antihypertensive, inhibition of platelet aggregation, enhance myocardial contractility, anti-myocardial ischemia and hypoxia, excite the central nervous system, improve memory, anti-tumor and other effects. Polysaccharides have antioxidant, anti-aging, antiviral, anti-tumor, immune-modulating, hypoglycemic and other effects. Saponins and polysaccharides play an anti-tumor role by stimulating the body to produce immunoglobulins, improving the body's anti-cancer cell effect.
In modern research, almost all of them are isolated by extracting and isolating the bioactive components of taro, analyzing and determining their biochemical properties, and exploring the function of these extracts in animal experiments or cell experiments (in vitro experiments). In cell or animal experiments, taro polysaccharides and taro saponins do show certain anti-cancer effects, but whether people eat taro has anti-cancer effects, how much taro can play such a role, and how long to eat need to be further human clinical trials to verify.
Primary bronchopulmonary cancer, abbreviated as lung cancer, is a malignant tumor that originates from the bronchial mucosa or gland. Lung cancer is currently the most common male malignant tumor in the world, with the highest incidence of tumors, and the prognosis is poor due to insufficient early diagnosis. Studies have found that people who eat less carotene-containing vegetables and fruits have an increased risk of lung cancer, and people with low serum carotene levels also have a higher risk of lung cancer. Epidemiological survey data show that more consumption of green (broccoli, spinach, water spinach, fungus, coriander, etc.), yellow and orange (carrots, sweet potatoes, pumpkin, yellow peppers, mangoes, papayas, etc.) containing carotene can reduce the risk of lung cancer.
There are also many anti-cancer recipes, anti-cancer rankings, anti-cancer pyramids, etc. circulating on the Internet. Garlic, which is touted to have a fairly high anti-cancer rate, is almost always said that these foods contain various antioxidant substances, which can inhibit or even kill cancer cells, but we should note that in vitro experiments and human trials are different, cancer cells are very fragile in vitro, and the extracted antioxidant substances can easily kill them, while in human trials, we use garlic as an analogy, how much garlic do we eat to achieve the dose of extract to kill cancer cells, this is difficult to judge, because eating a large amount of garlic will produce strong gastrointestinal irritation, and even induce gastrointestinal inflammation, resulting in the trial can not continue。 Therefore, there are currently no foods that are capable of producing definite anti-cancer effects.
Lung cancer patients do not need special supplements or eat some special foods, as long as they eat a healthy diet, have a reasonable mix, balanced nutrition, and develop a good diet Xi habits. The American Association for Cancer Research once published a food recommendation for cancer patients, all of which are relatively healthy diets, such as whole grains, broccoli, cauliflower, carrots, asparagus, tomatoes, pumpkin, garlic, grapefruit, grapes, blueberries, strawberries, nuts, cherries, coffee, tea, etc. Finally, it is recommended that lung cancer patients should eat more high-quality protein, whole grains, fresh vegetables and fruits, eat less high-salt, high-sugar, pickled, smoked, barbecued, fried foods, and drink less alcohol.
Significance of blood routine for cancer diagnosis:
1.White blood cells and neutrophils: These two indicators are elevated when the body has an inflammatory response, such as acute infection, poisoning, and trauma. Infectious diseases such as typhoid, influenza, viral hepatitis, malaria, etc., these two indicators will be reduced. In leukemia patients, leukocytes are elevated, and some naïve cells, that is, leukemia cells, appear in the white blood cell classification.
2.Red blood cells and hemoglobin: These two indicators are often used to determine whether a patient is anemic, and when these two indicators are low, anemia may occur. Infants, young children, older adults, and pregnant women may also have physiologic decreases in red blood cells and hemoglobin. Some people have problems with their bone marrow or their bodies are in a state of ischemia and hypoxia, and they need more red blood cells and hemoglobin to carry oxygen, which can increase the number of red blood cells and hemoglobin. Some people with cancer also have an increased number of red blood cells. In addition, people with leukemia have a decrease in the number of hemoglobin and red blood cells, which is manifested as anemia.
3.Lymphocytes: When infected by viruses, such as measles, rubella, chickenpox, mumps, etc., lymphocytes will be elevated. In addition, lymphocytes are also elevated in hematological tumors such as lymphocytic leukemia and lymphoma. Radiation damage or the use of corticosteroids may lower lymphocytes.
4.Monocytes: Monocytes can engulf pathogens, so they are elevated in certain infections, such as typhoid, tuberculosis, malaria, etc. In addition, monocytes are also elevated in certain blood disorders, such as monocytic leukemia, lymphoma, Hodgkin lymphoma, etc.
5.Platelets: Thrombocytosis is common in acute infection, fractures, blood loss, hemolysis, postsplenectomy, and essential thrombocythemia. Thrombocytopenia is commonly seen in thrombocytopenic purpura, aplastic anemia, leukemia, etc.
The blood routine can only make a preliminary judgment on the disease or cancer, and whether it is cancer or not also needs to be comprehensively judged through the patient's symptoms, signs and other specialized examinations.
