I copied this from the FoodMatters Instagram. You should go follow them!! Bananas For Cancer! You know when your bananas develop those brown spots when they become over-ripe? Well you'll be pleased to know that they can actually help fight cancer. Yes that's right! They encourage the body to produce a natural substance called Tumour Necrosis Factor (TNF) which helps fight the growth of cancer cells. A banana a day could help decrease your risk of developing cancer, plus they are a great source of fiber, potassium, manganese and vitamin C AND they are cheap, portable, low calorie and versatile!
