So far there is still no adequate evidence to show that the use of certain supplements is necessary to help reduce the risk of lung cancer. Even some supplements may have a counterproductive effect.
Beta carotene, a carotenoid, is thought to help prevent cancer for several reasons. The body needs it to make vitamin A. Carotenoid (orange, yellow, red, or fat-soluble compounds) can be found in many fruits, veggies, grains, and oils.
The studies that have observed beta carotene supplement show mixed results. Even some show that it may worsen the risk of lung cancer in smokers or those who have been exposed to asbestos. Furthermore, it doesn’t help reduce the risk in non-smokers.
Other bad things, it may also raise the risk of other health conditions such as heart disease and cancers of stomach, bladder, and prostate.
Beta cryptoxanthin, a similar substance to beta carotene, may be more promising. It can be found in certain fruits especially like mangoes and oranges. It may help reduce the lung cancer risk in non-smokers. But there is still no clearly answer whether it also works for smokers.
Vitamin E supplement
Vitamin E can be found naturally in some foods such as fruits, veggies, eggs, meat, cereals, wheat germ oil, and vegetable oil. It dissolves in fat.
As noted before, some vitamins (including vitamin E) were thought to have a role to decrease lung cancer risk. But today, it’s clear that vitamin E doesn’t affect the risk!
The same goes for aspirin. The results of the studies to it are also mixed. While some show that it works, other studies don’t find a link!
Aspirin may lower the risk if you take it (7 tablets a week), and if you are a man. Though if it does help reduce the risk, you should not take it regularly without prescription (ask your doctor first) since it can cause bleeding and damage the stomach lining!
If there are any substances in foods that do work to help decrease lung cancer risk, it’s much better to take it with food sources than in supplement or pill form!
