Banana Peels Can Purify Your Water!

A little off topic but in a word, bananas: Researchers have found that minced banana peels can quickly remove heavy metals from water!

In a new study published in Industrial & Engineering Chemistry Research, which I read while eating brown rice toast with sliced banana (no fooling!), researchers showed that the peels are a remarkably effective low-tech, low-cost solution to purifying rivers and streams that have been contaminated with metals. I’m going to assume it could work in your home, too!

A purification apparatus made of banana peels can be used up to 11 times without losing its metal-binding properties, they note. The team adds that banana peels are very attractive as water purifiers because of their low cost and because they don’t have to be chemically modified in order to work.

Mmmhmm. You see folks? Nature really does have (almost) all the answers.

    I thought you might be interested in this article, since it has to do with women/physical appearance/self-perception:,0,464632.story?track=rss

    . . . . “[I]t is disappointing to me that in the year 2011 so many young women continue to assert their self worth via their physical appearance — in this case, by posting photos of themselves on Facebook as a form of advertisement.”

    . . . . The people who tended to base their self worth on things like academic competence, family love and support, and being a virtuous or moral person spent less time online and showed less interest in attention-seeking through social media.

    (No surprising results here, but interesting enough.)

    That indeed is very cool. I wonder whether one should make sure that the bananas were not treated with pesticides?

    Sounds awesome, as long as you don’t mind banana flavored water. My toddler would love it!

    So, from now on I am going to recycle my banana peels in the stream. I love mother nature. She always has a clean, organic way to do everything. I think though, big companies hate it because it can’t be bottled and sold… And Kelu, good point. I had not thought of that, but I buy only organic food. Thanks for the story.
