A group called Sense About Science (SAS) is now lobbying against bunk health and sex advice endorsed by celebrities, including one wild claim that semen is highly nutritious when “reabsorbed” into the body.

Celebrities live in the public eye and they can easily sway the opinions of the masses—just ask marketers who pay millions of dollars for celebs to front their products. And many of these “wellness” suggestions pushed by famous people “promote theories, therapies and campaigns that make no scientific sense,” according to a statement issued by SAS.

Among the claims concerning the brainy watch group are hologram-embedded silicone bracelets said to promote energy and fitness (worn by sexy soccer star David Beckham and royal fiancé Kate Middleton); a crash detox diet of nothing more than maple syrup, lemon and pepper (used by Naomi Campbell, Ashton Kutcher and Demi Moore); and a sperm-reabsorbing habit pushed by UK cage fighter Alex Reid.

In Reid’s words: “… I believe that all that semen has a lot of nutrition. A tablespoon of semen has your equivalent of steak, eggs, lemons and oranges. I am reabsorbing it into my body and it makes me go raaaaahh.”

SAS counters Reid’s conjecture: “In fact, sperm die after a few days, and the nutritional content of the ejaculate is really rather small.” Guess we’ll just have to enjoy it for the flavor, then.
