I was just reading this article from Dr. Mercola. It gives you a lot of information about spirulina and all of the health benefits of it.
I am not too sure about the research in regards to protecting you from HIV, seems as though it is still preliminary in what it found out. Not sure if i read it right, but it appeared to say that the spirulina inactivated HIV-1 when it was put with the virus BEFORE adding it to human T-cell lines. I’m not doctor, but my interpretation is that spirulina stopped the HIV-1 but did so outside of the human body condition.
Anyways, the big takeaway for me about this article is about how important greens are in your daily food intake. Regardless if spirulina can defeat HIV-1 or not, you have to realize all of the health benefits as well as remember how you never hear about how beef is doing anyone groundbreaking benefit.
Enjoy the article and get some greens!
