Is Spirulina really good for our health ?

[JackBean]

And that is how?

I have been reading more studies recently that suggest supplements with Beta Carotene not only do nothing for cancer prevention, but they actually cause cancer. Spirulina contains Beta Carotene (at least my pills do).

Here is the info on the American Cancer Society website:

Does anyone have any research to the contrary?

Conclusion of the relevant research was not that beta carotene causes cancer. Long-term high-dose treatment (in smoking-associated population) was associated statistically with increased cancer risk. The study was not claimed to show risk for other populations with lesser exposures.
There are studies that concluded some cncer prevention potential of carotenoids - here's a review:
