It has been recently found that Bananas are rich in a sugary protein called BanLec, a Lectin which attaches to the HIV Envelope and protects the body from being able to get the virus through sexual transmission. It clings to the binding of the sugar rich HIV envelope when it enters the body and does not let go. It would take several mutations for the virus to get loose from the Lectins, which by that time, your body would have grown immune to that certain strand from the BanLec in your system.

BanLec has had such a huge success in preventing the transmission of HIV that there are many countries considering using it as an injection that would go right into the anus or vagina and could protect a person for up to three years. Another possibility, although not as popular due to the lack of condom use, is to add it to the spermicide already in condoms, this would make them more effective at not only killing sperm but also in the prevention of, at least HIV if not other STDs, something that has never been done before. It has also been said that the power of the BanLec is twice as strong as many of the antiviral HIV medications that are given to patients currently.
