US institutions: cancer prevention is not recommended to take vitamin E

The US advisory body, the US Preventive Services Working Group, issued a statement on February 25 that the supplement of vitamin E health foods for the purpose of preventing heart disease and cancer has been changed to “not recommended (D)”. It is said that the US Preventive Services Working Group has launched a number of evaluation actions for disease prevention. The evaluation results are divided into four levels from “strongly recommended (A)” to “not recommended (D)”. As “the research evidence is not sufficient (I)”. Taking vitamin E to prevent heart disease and cancer has changed from “insufficient research evidence” to “not recommended” in the past.

In 2003, the US Preventive Services Working Group issued a recommendation that for healthy adults, the prevention of heart disease and cancer by supplementing vitamin-type health supplements including vitamins E, A, C and folic acid is not sufficient. It is classified as “research evidence is not sufficient”. It was beta carotene that was clearly stated at the time as “not recommended”.

According to the results of this latest study, vitamin E and beta carotene are classified as “not recommended” because their preventive effects on heart disease and cancer have been unanimously rejected by the Committee of Preventive Medicine experts worldwide. .

In addition, the working group also added relevant content to beta carotene. While publicly reflecting the opinions, it was pointed out that beta carotene is harmful to people with high risk of lung cancer. Vitamins A, C, D, folic acid, selenium, complex vitamins, calcium and other elements are still classified as “incomplete research evidence.”

It should be emphasized that children, pregnant women, sub-health, hospitalized patients, and patients with nutritional deficiencies are not within the scope of the announcement.
