Banana Halts Prostate Cancer Growth by >80%:
An extract of banana peel (from organic bananas) was shown slow the growth of prostate cancer cells by over 80% in this study, by inhibiting the production of dihydrotestosterone (DHT). Prostate enlargement (Benign Prostatic Hyperplasia, or BPH) in men is also caused by excess DHT, so in theory banana peel extract could also help with this condition.
Intriguingly, this is exactly what was observed with mice in this same study—their prostate overgrowth was significantly inhibited by banana peel extract. What makes banana peels so special?
Previous lab studies have shown them to be rich sources of powerful antioxidant and anti-inflammatory compounds. Although no studies have been done using banana peels on humans, several population studies have shown that regular banana consumption may reduce colon cancer risk by up to 72%, breast cancer risk in women by 43% and kidney cancer risk by 46%.
Bananas (and peels) are also rich sources of melatonin: in fact, eating two bananas quadrupled melatonin levels in healthy adults in one recent study. This is relevant to prostate cancer: another study from Europe showed that men with the highest levels of melatonin had 75% less risk of prostate cancer!
And alkaline diet fans take note: one medium banana has the same alkalizing power as 1.5 cups of pure lemon juice!
