Transcript

Speaking of which, does an apple a day really keep people like me away? By which I mean, is there scientific evidence that just one apple a day has significant, measurable benefits. Remember, the recommended minimum number of daily fruit and vegetable servings is nine a day—minimum. Is a single apple going to do anything? What do you think? An apple a day, fact or fiction?
Fact. A major recent review found that compared to those eating less than an apple a day, those eating just one or more had less risk of oral cancer, less cancer of the larynx, less breast cancer, less colon cancer, less kidney cancer, and less ovarian cancer.
This makes sense given new research showing, for example, that apple peels have potent antioxidant and antiproliferative effects on human cancer cells in a petri dish. The higher the apple concentration, the more the growth rates of human cancer cells drop, compared to control. Same with breast cancer. And apples seem to work best against estrogen receptor negative breast cancer, which is much harder to treat than estrogen receptor positive breast cancer.
How do apples do what they do? Those of you who have seen my stopping cancer DVD will recognize these stages of tumor formation. Carcinogens cause DNA mutations, and then then oxidation, inflammation, and hormones cause it to grow and finally metastasize. Which steps do apples block? All of them. Antimutagenic, antioxidant, anti-inflammatory effects, and even immune enhancement to help clear out any budding tumors. Eat at least an apple a day.

    Hello Dr. Greger,
    Quick question: regular apples are covered with wax to make them shiny and washing them does not remove it. Is that bad for us or do we just digest it?
    Thanks :)

    At age 29 I was diagnosed with a meningioma after the birth of my daughter. I had radiation therapy for it and now I am monitored every year with an MRI. It has been six years and my pituitary gland is struggling to produce Estrogen and I have not had a period in 2 years. They are talking about hormone replacement, but I worry about tumor re-growth. Is there any food that is above others to help my pituitary gland recover from the radiation?
