Does eating sugar make cancer worse?
Does eating sugar make cancer worse? Can cancer patients eat sugar? Should I eat more, less, or not?
There is always an unexplainable relationship between sugar and human health. Especially for cancer patients, various “rumors” about sugar and cancer cells spread widely. Today, a good doctor came to tell you what we should know about sugar.
01. Does eating sugar make cancer worse?
will not. Although studies have shown that cancer cells consume more sugar (glucose) than normal cells, no research has shown that eating sugar can make cancer worse, or that if you stop eating sugar, the cancer will shrink or disappear. However, a high-sugar diet may lead to excessive weight gain, and studies have shown that obesity can lead to an increased rate of recurrence and metastasis of breast cancer.
02. Blocking the source of sugar can starve cancer cells?
The rumor that “sugar can nourish cancer cells” has been around for a long time, and some patients are convinced and believe that “cancer patients should eliminate sugar.”
But in fact, compared with normal cells, cancer cells only have a greater demand for sugar, and this kind of sugar is not the sugar that we can touch in our daily life, but is caused by sugar (carbohydrate) in the human digestive system. Hydrolyzed into glucose and fructose.
“Sugar” is a general term, which is a series of molecules, including the monosaccharides (glucose, fructose) naturally occurring in plants. We usually use sucrose for cooking and seasoning, which is composed of glucose and fructose through chemical bonds. Sugars (carbohydrates) are hydrolyzed into glucose and fructose in the human digestive system, and then absorbed into the blood, and then enter the cells as raw materials for respiration to provide us with energy. All cells in our body, whether cancerous or not, need glucose to provide energy.
There is evidence that the metabolic pathways by which cancer cells break down glucose production are also different from normal cells. Therefore, researchers are conducting research on the pathways of carbohydrate metabolism in cancer cells and hope to find more effective cancer treatments.
03.Can cancer cells starve to death without eating?
Cancer cells can use a lot of sugar to promote growth and spread. They especially love sugar, so let’s not eat and starve them to death.
It sounds reliable, but there is a problem. Cancer cells need energy, but many cells also need energy. For example, nerve cells in the brain and immune cells in the body. So usually, before cancer cells are starved to death, cancer The patient has developed malnutrition.
Statistics show that 20% to 30% of patients in China eventually die due to malnutrition. Therefore, Mi Friends should not blindly believe in starving cancer cells. Cancer patients need to eat well and to be full.
04. Is it true that online mannose can fight cancer?
In 2018, the research on the anti-cancer effect of mannose published in the top academic journal “Nature” caused heated discussion. For the first time, mannose was found to destroy the glucose metabolism of tumor cells and inhibit tumor growth. From cell experiments to mouse experiments, the inhibitory effects of mannose on a variety of cancers have been confirmed. In addition, mannose can significantly enhance the effect of chemotherapy.
Although mannose has great anti-cancer potential, it is still too early to eat mannose to prevent or treat cancer.
On the one hand, this result has not been confirmed in human clinical trials, only conclusions were obtained in mouse experiments; on the other hand, the concentration used in this experiment is very high, which may not be suitable for humans, and further optimization is needed.
Although mannose is widely present in some fruits, it is not realistic to expect that some mannose in fruits can achieve the purpose of fighting cancer. But eating some fruits is good for cancer patients to maintain a balanced nutrition.
05. How should sugar be consumed reasonably?
◎ Control sugar intake
Ensure the human body’s minimum intake of sugar, avoid or eat as little sugar as possible, and eat more low-sugar foods. The World Health Organization recommends that the intake of sugar per person per day should be less than 50 grams.
◎ Eat less high sugar content
Although some foods do not feel sweet, the sugar content in them is surprisingly high. Sucrose, lactose, maltose, honey, and corn syrup are all sugars. The more the ingredients are listed in the front of the food ingredient list, the higher their content.
Brown sugar/white sugar/rock sugar: brown sugar is derived from sugar cane, with a sugar content of 88% to 86%. When it is refined into white sugar and rock sugar, the sugar content is as high as 99.5% and contains almost no other nutrients. Cancer patients cannot directly edible.
Fructose: The sugar content of various fruits is between 10% and 20%, and the fructose content is relatively low, and the fruits also contain a lot of vitamins, dietary fiber and other nutrients. It is recommended that patients consume 300g of different types of fruits daily. However, the content of fructose in refined juices and soft drinks is very high, and does not contain other nutrients of fruits, cancer patients should be cautious.
Therefore, desserts such as beverages, candies, bread, snacks, biscuits, energy bars, jams, jellies, candied fruit, ice cream, ice cream and other desserts that use monosaccharides and disaccharides as materials should be eaten as little as possible.
You should also pay attention to cooking, try to avoid sweet and sour, braised and other methods, and adding sugar not only increases sugar intake, but also masks the taste of salt, which will also increase salt intake unintentionally.
◎ Mainly low-sugar foods
Low-sugar foods mainly refer to staple foods that we consume starch polysaccharides, as well as coarse grains, fruit and vegetable foods that consume dietary fiber. Starch and dietary fiber are also called polysaccharides.
The recommended amount of rice, noodles, and potato staple food for healthy people:
Although staple foods also contain sugar, they belong to starch polysaccharides. They are not as fast as refined sugar to raise blood sugar. They are the most economical energy source for our body. In addition to sugar, staple foods can also provide a variety of human body characteristics. Other nutrients needed, such as dietary fiber, vitamins, etc.
Reducing the consumption of staple foods can easily cause side effects such as drowsiness, drowsiness, hypoglycemia, nausea, vomiting, and dyslipidemia, which endangers health.
Dietary fiber is a kind of sugar that the human body cannot digest. It mainly comes from whole grains, vegetables, whole grain foods, fruits and nuts, etc.:
Dietary fiber can absorb water in the digestive system, increase the volume of food in the intestines and stomach, increase satiety, and reduce the intake of other sugary foods; dietary fiber can also absorb harmful substances in the intestines for excretion , Improve the intestinal flora, promote gastrointestinal motility, relieve constipation; in addition, dietary fiber can also regulate blood sugar, blood lipids, and reduce the risk of cardiovascular diseases, cancer and other major diseases.
Warm reminder: Ensuring adequate staple food, appropriately increasing high-fiber coarse grains and whole grains, eating less sweets, drinking less beverages, and eating more vegetables and fruits are the basic dietary principles for cancer patients!
