RationalWiki's 2019 Fundraiser

There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

If everyone who saw this today donated $5, we would meet our goal for 2019.

Fighting pseudoscience isn't free.
We are 100% user-supported! Help and donate $5, $20 or whatever you can today with PayPal Logo.png!

Donations so far: $4200Goal: $6000

Chlorella is a genus of green algae. Due to the fact that Chlorella is high in protein, calories, fat, and other nutrients, there was once a great deal of interest in the possibility of developing Chlorella-based substitutes for certain foods. This would, in theory, be a simple way of delivering food with high caloric content to the Third World.[1] Today, it is more popular as a staple of health food quackery and often marketed as a "superfood".

Hardcore woo-meisters will hawk it as part of detox diets or chelation regimens as it allegedly flushes "toxins" and heavy metals out of the body.[2] Unsurprisingly, like many organisms, Chlorella produces its own toxins: lipopolysaccharides that can cause inflammation.[3]

Like most food woo, Chlorella is advertised on any and every diet page that will take their advertising money. With no evidence whatsoever, it is sold as a supplement that makes weight loss easier, in that vague, non-committal, not testable way that is so popular with food wooists.
