Diabetes mellitus type 1 (also known as type 1 diabetes, or T1D; formerly insulin-dependent diabetes or juvenile diabetes) is a form of diabetes mellitus that results from the autoimmune destruction of the insulin-producing beta cells in the pancreas.he cause of diabetes mellitus type 1 is unknown. Type 1 diabetes can be distinguished from type 2 by autoantibody testing. The C-peptide assay, which measures endogenous insulin production, can also be used. Administration of insulin is essential for survival.
Vegetarians refrain from eating any product that has animals in it, including meat, poultry, fish, and gelatin. Strict or pure vegetarians (also known as vegans) also refrain from eating anything that comes from an animal, including dairy, eggs, and honey.
Neither vegans nor vegetarians eat meat. However, while vegetarians tend to consume dairy products and eggs, a vegan avoids all animal products, including eggs and dairy, and often inedible animal-based products, such as leather, wool, and silk.
