5. To Eat: Fermented Foods
It may sound wild, but fermented foods like kimchi and yogurt may help protect against breast cancer. These foods positively boost the immune system, thanks to their high levels of probiotics. According to many studies, fermented dairy products can even reduce the risk of breast cancer in Western and Asian populations. Therefore, it is a good idea to eat some yogurt, pickles, or sauerkraut from time to time.
