Onions can not only fight cancer, but also reduce three highs? Should onions be eaten raw or cooked? Here comes the answer

Sister Lin is 52 years old this year. She used to run a breakfast restaurant and got up early every day. In the past two years, my health has not been very good, so I closed the breakfast shop and rented the shop to others. Whenever I have time, I go shopping with my sisters and live a beautiful life.

When it comes to food, Ms. Lin from Chongqing has a strong taste and likes spicy and exciting food, including spicy hot pot, snail noodles, and hot and sour noodles.

About a year ago, during a routine physical examination, Sister Lin was found to have a breast nodule, and the doctor told her to review it regularly. It was from this time that Sister Lin began to change her eating pattern, and she ate a lot more lightly.

Later, an old friend told her that breast nodules may be at risk of cancer. You can eat more onions to "kill" cancer cells and prevent nodules from becoming cancerous .

Although the taste is very spicy, Sister Lin insists on eating an onion raw every day. After eating like this for a while, Sister Lin felt that her stomach was always bloated, often indigestion , and she wondered if she was eating onions. But in order to prevent breast cancer, Sister Lin persisted.

But during the review last week, the doctor told her that her breast nodules had gotten bigger!

Sister Lin was stunned and asked the doctor, " Can onion prevent cancer? Why did I eat it for a year, but it caused this result? "

The doctor didn't know whether to laugh or cry, "Where did you hear this recipe? How could eating onions have the effect of treating nodules? Eating too much is bad for the stomach." Sister Lin was speechless, thinking that she had eaten onions for a year, As a result, not only did the treatment have no effect, but it also hurt his stomach.

1. Can eating raw onions "kill" cancer cells?

Onion is a common ingredient in life, and eating onion properly is good for health. But can it really "kill" cancer cells? Where did the saying "onion fight cancer" come from?

This has to be traced back to a study in Canada. In order to test the anti-cancer power of onions, scientists selected 5 different types of onions for experiments, and finally found that "ruby" onions had the most significant anti-cancer effect.

This is mainly because it is rich in anti-cancer active substances such as quercetin and anthocyanin, which have a certain anti-cancer effect .

So, are onions really "anti-cancer holy products"?

In this regard, Pan Zhanhe, deputy chief physician of the Department of Oncology, Zhongshan Hospital Affiliated to Xiamen University, said that the presence of certain anti-cancer active substances in a certain food does not mean that eating this kind of food can have anti-cancer and anti-cancer effects .

Moreover, even if these anti-cancer active ingredients are proven to be useful in the human body, the effect of eating this food alone may not be ideal, and the amount supplemented by eating onions is only a drop in the bucket.

So, don't expect to just eat an onion to have anti-cancer and anti-cancer effects. A balanced diet and a reasonable combination are the core strategies for diet prevention of cancer.

2. Onions are edible "heart stents", and can they lower the third height?

Regarding the efficacy of onion, there is also a widely circulated "heart stent" that can be eaten. Are onions really so amazing?

Onions are indeed rich in nutrients, including protein, water-soluble vitamins, calcium, iron, selenium, and various nutrients such as flavonoids, steroids, and polysaccharides.

Everyone should take a rational view of the statement that onions are edible "heart stents".

Although it contains certain substances such as prostaglandin A, flavonoids, and cycloaliin, which are helpful for the prevention and treatment of cardiovascular and cerebrovascular diseases , the effect is not obvious due to the small content .

As for the reduction of the third high, it is also a truth. The amount of onion consumed in the daily diet alone cannot achieve the effect of reducing the third high .

In short, although onions have a certain nutritional value, do not try to achieve the effect of treating diseases by eating onions, which will often only delay the treatment of the disease.

3. Should onions be eaten raw or cooked?

How to eat onion is also very particular, some say it is better to eat raw, some say it is better to eat cooked, so which one is better?

In most cases, eating raw is better, because some components in onions, such as organic sulfur compounds, are volatile and will be lost significantly once heated or exposed to the air for too long . Raw onions can retain as much as possible. Nutrition.

However, it should be noted that there are many types of onions, and different onions have different specific ways to eat them. For example, white onions are suitable for raw consumption, and red onions are suitable for stir-frying. Everyone decides how to eat them according to the specific onions.

In addition, Zhang Dongmei, chief physician of the Department of Endocrinology, Xiangya Hospital of Central South University, reminded that the following three points should be paid attention to when eating onions:

1, prefer purple onion

2. Do not eat in excess
