How to prevent throat and oral cancer

How to prevent laryngeal cancer and oral cancer? Many people are afraid of cancer, but there is no need to panic. There are many simple and easy ways to prevent cancer in life. Eat more foods that help prevent cancer, and delicious citrus is one of them. Let's learn about the prevention methods below.

The results of a 13.6-year follow-up survey of more than 40,000 people by the Catalan Institute of Oncology in Barcelona, ​​Spain. During the study period, a total of 1,915 people died, of which 956 died of cancer. The results showed that the mortality rate of the group of subjects with the highest intake of flavanones and flavonols decreased by 40% compared with the group with the lowest intake. The researchers explained that some flavonoids have the effect of preventing cancer and enhancing cancer resistance. Hesperidin, which is rich in citrus, belongs to the flavanone compound, and rutin, which is rich in buckwheat, belongs to the flavonol compound. Eating more citrus and buckwheat can help prevent cancer.

Flavonoids are widely found in fruits and vegetables, beans, and tea. The reason why they can help fight cancer is mainly based on their antioxidant effect. As early as 2005, an Australian study found that eating an orange every day can reduce the risk of oral cancer, laryngeal cancer, and stomach cancer. The main reason is that citrus is rich in vitamin C, an antioxidant that can protect the human body, enhance immune function, and inhibit the growth of tumor cells. The pulp of fresh citrus is rich in vitamin C, which is dozens of times higher than that of apples, pears, grapes, etc. The vitamin C content in orange peel is even higher than that in the pulp. In addition to citrus, foods rich in vitamin C also include kiwis, cherries, etc.

In addition to antioxidants, β-zeaxanthin in citrus also has anti-cancer effects. A Japanese study confirmed that the sweeter the citrus, the better the anti-cancer effect, because the higher the sugar content, the more β-zeaxanthin it contains, which is 5 times more effective than the anti-cancer effect of β-carotene contained in carrots. Ordinary people can achieve good anti-cancer effects by eating two sweet citrus fruits a day.

It should be noted that although citrus fruits have many benefits, they should be eaten frequently but not too much. First of all, eating too many oranges can easily cause "getting angry", resulting in symptoms such as mouth sores, dry mouth, sore throat, constipation, etc. Secondly, because citrus fruits contain a lot of carotene, if you eat too much at one time or take too much in a row recently, it will cause the concentration of carotene in the blood to be too high, which will lead to yellowing of the skin, so it is advisable to eat 1 to 3 (about 50 to 200 grams) each time. Finally, the pulp of citrus fruits contains organic acids. In order to avoid excessive stimulation of the gastric mucosa and cause discomfort, it is best not to eat citrus fruits on an empty stomach. People with stomach problems should pay more attention to this. They can eat some easily digestible staple food before eating oranges.

Oranges are high in sugar, so diabetic patients should eat oranges in moderation. They can choose to eat one or two oranges one hour before or two hours after a meal. It should be noted that after eating these fruits, it is best to reduce some calories in the staple food.
