YEAST


Baker's Yeast (Saccharomyces cerevisiae)

Observation
I took a picture of this yeast product at the Whole Foods Market in Jenkintown, PA. Red Star is just one of several brands that sell active yeast for baking. My mother has used yeast to make bread or rolls. Once the dough was formed, she would place it in a warm dark place. After several hours, the bread would rise and would be ready to bake in the oven. The dry yeast has a grainy consistency and a very unique odor.
 
Questions
In what food processes are strains of  Saccharomyces Cerevisiae used? Is Crohn's Disease caused by of S. Cerevisiae? Is S. Cerevisiae a  pathogen?
  
Scientific Research
Main, J., McKenzie, H., Yeaman, G R., Kerr, M A., Antibody to Saccharomyces Cerevisiae (Bakers Yeast) in Crohn's Disease , British Medical, Vol. 297 (Oct., 1998), pp. 1105-1106.

Strains of Saccharomyces cerevisiae are used when baking and brewing food. It is also present in many other food products. Studies show that Crohn's Disease is not caused by Saccharomyces Cerevisiae. Instead, Crohn's Disease may be the result of a hypersensitivity to the Saccharomyces Cerevisiae antigen. It does not cause the disease because Saccharomyces Cerevisiae is not a pathogen.

Though Saccharomyces Cerevisiae is not responsible for Crohn's Disease, studies suggest that it may helpful when trying to differentiate Crohn's Disease from Ulcerative Colitis.
