Top ten anti-cancer foods
Various lists of anti-cancer foods are often circulated on the Internet, with broccoli, garlic, asparagus, carrots, green tea, onions and so on at the top. But if you want to first, these foods can't be ranked. What is the strongest?
Sweet potato!
Every time on the list, sweet potato is the champion of the year. There is even an upgraded version. Some people further distinguish that cooked sweet potatoes are more cancer-proof than raw sweet potatoes, and eating sweet potatoes at noon is more cancer-proof than eating them at night.
Does sweet potato really have anti-cancer function? That's right, and that's not right.
If you want to eat sweet potatoes alone, you won't get cancer. It is definitely impossible. In fact, so far, no food has been scientifically proved to reduce the incidence of cancer.
There are three common ways to eat sweet potato, a so-called anticancer food, which are all wrong.
First, I firmly believe that eating sweet potatoes can prevent cancer. As long as you eat more sweet potatoes, you buy insurance, so you start to indulge, and bad habits such as smoking and drinking come.
Sweet potato is not a magic medicine. It's fantastic to toss your body every day and try to resist the harm of alcohol and tobacco by eating sweet potatoes.
Secondly, I heard that sweet potato can prevent cancer and is a good food, so I only eat sweet potato and don't eat much else. Meat, eggs and milk do not prevent cancer and are not eaten at all. These people, it is estimated that they have not waited to verify whether sweet potatoes really prevent cancer, because they lack a variety of nutrients and are seriously malnourished, and they have other diseases first. This way of preventing cancer is not worth the loss.
Third, eat one more sweet potato every day on the basis of the same daily eating habits. In fact, this diet is likely to lead to excessive calorie intake, and in the long run, it is easy to get fat. Overweight and obesity will significantly increase the risk of 10 cancers, such as liver cancer, rectal cancer, breast cancer, gastric cancer and so on. Is eating sweet potatoes like this cancer-preventing or carcinogenic?
In fact, the foods in these cancer prevention lists are very good and healthy, so it's no problem to eat more. But you can't go to extremes. If you want to eat two more sweet potatoes, two broccoli and two garlic every day, you won't get cancer. That's not reliable The official nutritional dietary guidelines of various countries, including the recommendations of anti-cancer associations, advocate a balanced diet. Protein, fat and carbohydrate should be eaten, which is the best choice.
The correct way to eat sweet potatoes
Although it is not enough to eat sweet potato alone, eating sweet potato correctly with other foods can really achieve the effect of preventing cancer.
Sweet potato is really good food. As a staple food, it contains more dietary fiber than rice and white flour that we often eat. Strong scientific evidence shows that eating more foods containing dietary fiber can prevent rectal cancer. At the same time, eating foods with high dietary fiber content, such as sweet potatoes, is more likely to produce satiety, thus avoiding excessive intake of food and calories, preventing weight gain and obesity, and also reducing the risk of various cancers.
So, how should I eat? Quite simply, the correct way is to take sweet potatoes as the staple food, not some rice or noodles in our daily diet.
Eating sweet potatoes in this way can actually reduce the risk of cancer in theory.
Having said that, you should be able to see that the essence of eating sweet potatoes to prevent cancer is not the food itself, but the intake of dietary fiber and the control of energy. High dietary fiber content is not the patent of sweet potato. Controlling energy is not unique to sweet potatoes. If a food contains a lot of dietary fiber, which can help control calorie intake, then it may be an anti-cancer food.
What really prevents cancer is the overall diet pattern and lifestyle. When we discuss whether to eat or not to eat a certain food, whether to eat more or less, we should not only look at the food itself, but also examine its impact on health from the overall perspective of dietary intake and living habits. The most taboo is to flaunt the omnipotence of star food.
If you want to eat more of a certain kind of food, you should first get used to asking some questions, such as whether it will affect the overall energy intake, what good nutrition you can bring, and what foods you need to reduce at the same time. The overall dietary pattern is far more important to health than a single food or nutrient. There is no absolutely perfect single food in the world. Simply deifying or belittling any kind of food is hooliganism.
Calm thinking in the era of information explosion
Everyone wants to eat healthily. In today's information explosion environment, countless topics about eating are filled with our lives, and various statements come and go. It is good to eat this today, but it is not good to eat that tomorrow. The information on the Internet, whether true or false, once spread out, is likely to cause public anxiety and even make some food looted. Japan's Fukushima nuclear power plant leaked and salt was robbed; When COVID-19 came out, all the garlic was robbed.
Scientific research proves that in today's media age, rumors are far easier to spread than the truth. Science magazine published a cover article entitled "How Lies Spread", which specifically talked about this issue. Statistics show that the probability of rumors being forwarded is 70% higher than the truth. The number of people who forward rumors often exceeds 10 times, or even 100 times. Serious rumors are viral, and the truth is rarely viral.
And you think only elders like to forward rumors? All wet. In fact, people of any age, gender and education prefer to forward rumors, but they are interested in different topics. Elders like to spread pseudoscience of health preservation because they are more concerned about this topic. If it is a rumor related to the entertainment circle or children's education, then young people are the absolute main force. Basically, as long as it is not a professional field that you really know, no one can be spared. I can't remember how many non-biological doctoral students have been instilled with the idea that "vaccines don't cause autism" or "garlic can't prevent cancer".
To resist the temptation of rumors, we need to improve our scientific thinking ability. In today's fast-paced society, it is normal to judge information quickly. Fragmented information and headline party news make us more and more inclined to obtain simple, fast, straightforward and absolute information. Without rational and scientific thinking, it is particularly easy to be attracted by simple and absolute information and help spread it.
But the real scientific conclusion needs to consider the preconditions and specific scenarios, and it is never black and white. Truth is always more complicated than rumors. The world runs very fast, so we should slow down and think more, and don't be kidnapped by all kinds of information. In this way, we will not only get health, but also reduce anxiety and get peace.
