Stop throwing away bananas with brown spots – they are potent cancer fighters!

We all tend to dispose of our food when they have made it to their sell by dates. 

Bananas are subject to this and when they have brown spots on the skin, people tend to throw them away. What they don’t know, is that there are health benefits to those brown spots. In fact, it has cancer-fighting properties within it. 

Bananas and TNF

TNF is a protein that eliminates cells, tumor cells in particular. TNF functions by finding cancer cells and destroying them. The Food Science and Technology Research published an article that explained how over-ripe bananas with brown spots, are at their best in the production of tumor necrosis factor (TNF), a cytokine that helps ward off cancer.

The study was conducted by Masatoshi Yamazaki and Haruyo Iwasawa, and they found that mice cells that consume older bananas increased the production of TNF, in in vitro tests. Bananas are able to do this by encouraging the production of cytokines. It was even discovered that over-ripe bananas are 25% more effective in TNF production. 

The study was mainly performed on mice cells through in vitro tests, so there still is a lot of work to do, before we can even say that bananas aid in TNF production to fight cancer. 

Antioxidants and Cancer

We hear more of antioxidants being able to prevent cancer, than how it is being eliminated by TNF. Consuming foods that are rich in antioxidants means you must eat food thats abundant in vitamin C, vitamin E, beta-carotene, selenium, and zinc. Antioxidants harm your cells by extracting electrons from molecules and atoms. Through alteration of molecules and atoms, it harms chromosomes and cells, and opens the door for cancer. Antioxidants aid in transferring free radicals an electron, so that they don’t harm other cells for it. 

Animal trials have so far, been showing that antioxidants do help, while in human trials there is no set decision on that. When you eat a banana it could be providing you with more TNF than much-needed antioxidants.
