One, lettuce is the king of anti-cancer, can kill cancer cells, alleviate the side effects of chemotherapy?

Rumor has it that studies have found that lettuce contains aromatic hydrocarbon hydroxyl ester components, which can play a preventive role in liver cancer and stomach cancer, and can also alleviate the side effects of chemotherapy in cancer patients, is a real anti-cancer vegetable. Is this true?

In fact, it's impossible to eat romaine lettuce to fight cancer.

One is that the active ingredients in romaine lettuce are very limited. Most of the lettuce extracts used in the study were extracts of lettuce, and you need to eat several pounds or even dozens of pounds of lettuce at one time to get an effective dose, which is obviously difficult to do.

The second is the loss of nutrients and the lack of absorption. Lettuce in the body for digestion, there will be a lot of ingredients lost the original effect, which will make the lettuce "anti-cancer" role discount.

The American Institute for Cancer Research (AICR) clearly states that there is no clear evidence that specific food ingredients cause cancer or protect people from cancer. WebMD, a famous medical website, even makes it clear that there is no diet that can cure cancer or prevent its recurrence, and that the best dietary pattern is to maintain a balanced diet rather than a single diet of only one type of food.

Two, these 3 are the benefits of eating lettuce

Although eating lettuce can not play a role in the fight against cancer, but it does not mean that eating lettuce does not have any usefulness, these 3 benefits are still visible.

1, help digestion, relieve constipation

Lettuce within a large amount of crude fiber, into the body can promote gastrointestinal tract peristalsis, help to improve constipation, to prevent dry stools.

2, improve sugar metabolism

Lettuce is low in sugar and contains malic acid, niacin and succinic acid and other nutrients, which can help improve sugar metabolism, and it's also very suitable for diabetic patients to eat.

3, promote urination

Lettuce within the potassium is also very rich, can play a diuretic role, but also assist in lowering blood pressure, to prevent arrhythmia. And lettuce is also rich in iron, for iron deficiency anemia is particularly friendly to the crowd.

It is important to note that lettuce is not suitable for everyone, for those who suffer from eye disease, spleen and stomach cold and diarrhea, it is generally not recommended to consume lettuce, otherwise it is easy to lead to their own discomfort aggravated.

Three, the inventory of those blown on the day of anti-cancer food, do not believe

In addition to lettuce, there are many foods are held up on the "altar", claiming to have an anti-cancer effect, however, these are also not credible.

Journal of the American Medical Association - Oncology published a paper on the relationship between yogurt and lung cancer, the authors collected data from the past 10 surveys on the correlation between yogurt and lung cancer, with a total of 1.45 million people involved. The analysis found that the 20 percent of people who drank the most yogurt were 19 percent less likely to develop lung cancer than those who didn't drink yogurt.

So is it safe to say that drinking yogurt can fight cancer?

In reality, the study was a meta-analysis, not a research study, and did not specify the mechanism of occurrence between drinking yogurt and reducing the incidence of lung cancer. And the paper was not unanimously accepted by the academic community. Let's just say that continued research is needed, and you can't say that yogurt fights cancer based on this paper alone.

It is undeniable that yogurt, as a dairy product, is a food high in calcium and protein, and can be an excellent part of food diversity. China's dietary guidelines recommend that adults keep their daily intake of dairy products at about 300ml.

Western bluebells within some of the components of the animal experiments have been confirmed to have inhibited the occurrence and development of cancer, but the same experiments used in the for the extract, want to dietary intake of sufficient amount, you need to eat a few kilograms or even dozens of kilograms, not to mention that the amount of intake can not reach, the results of the animal The results of the experiments can not be directly extrapolated to the human body.

Garlic contains allicin, which is considered by many to have anti-cancer properties. However, allicin ≠ garlic, and the allicin content within garlic is very limited. There is no evidence that there is a clear relationship between garlic and anti-cancer, and eating garlic to fight cancer is obviously not reliable.

The tea polyphenols in tea have been found to have a preventive effect on lung and colon cancers in cell and animal studies. However, there is a lack of direct evidence regarding whether it has the same effect on humans.

In addition to fighting cancer, there are rumors that drinking tea can help prevent AIDS. This stems mainly from the catechin component within tea, which is rumored to inhibit the influenza virus from binding to host cell membranes. But catechins are chemically unstable, easily metabolized, and membrane permeability is poor, it is difficult to play a role in preventing AIDS.

Cancer is associated with a variety of factors, and it is difficult to fight cancer with a single food. However, the risk of cancer can be minimized through healthy eating patterns. The American Institute for Cancer Research suggests that eating more fruits and vegetables, whole grains, legumes, and other plant foods on a daily basis can be beneficial in reducing the risk of many types of cancer.
