The U.S. National Cancer Institute conducted an 8-year study involving 29,000 Finnish men, including 1,144 lung cancer patients. They continuously measured the levels of vitamin E in their blood and examined the relationship between these levels and their health conditions. The researchers concluded that there is a certain correlation between the level of vitamin E in the blood and the incidence of lung cancer. Higher levels can reduce the incidence rate by 19-23%. The preventive effect was most significant for men under 60 who had smoked for less than 40 years and did not smoke heavily.
However, the researchers also pointed out that this preventive effect comes from a balanced diet that includes foods rich in vitamin E, not from taking vitamin E supplements. The best way to avoid cancer is not to smoke.
Foods rich in vitamin E include vegetable oils such as soybean oil and oils extracted from plant seeds, as well as nuts and whole grains. Specifically, these include nuts like apricots, almonds, hazelnuts, walnuts, and sunflower seeds, and whole grains.
