Food sources: Vitamin B12 is found naturally in animal products (such as fish, poultry, meat, eggs, or dairy); it is also found in fortified breakfast cereals and enriched soy or rice milk. Most people have plenty of vitamin B12 in their diets. The main concern is whether vitamin B12 is adequately absorbed.
From Conservapedia. The Germ theory of disease, developed in the 1860s and 1870s by Louis Pasteur, states that tiny living beings are the cause of infectious diseases. The theory was developed to explain puerperal fever, or Child bed fever.nly after the germ theory was championed by Pasteur (see pasteurization) and Lister (namesake of Listerine mouthwash) did antiseptic medicine become popular. Prior to germ theory, it was widely believed that disease was spread by noxious odors.
Causes vs. Treatments. While germ theory may have revolutionized understanding of the causes of disease, it did not necessarily revolutionize treatment. Vaccination was an empirical procedure that had been developed almost 80 years earlier.he great decline in mortality associated with the end of the 19th century is not associated with the impact of the germ theory, but with improved sanitation and nutrition. The identification of a disease germ does not necessarily lead to a cure for that disease.
