Red meat is directly linked with cardiovascular disease because of its Saturated fat. This has been proven may years ago and a person is having a cardiovascular disease should either cut-down or avoid red meat. But this is just the beginning of the story.
Diabetes occurs when the body’s ability to control blood glucose levels by means of insulin secretion becomes impaired by insulin resistance. This can cause two ways. One is, when glucose uptake by muscle and tissues, insulin fails to trigger effectively. Second one is, production of insulin by beta cells in the pancreas declines.
Most probably there are three components of red meat- Sodium, nitrites and iron are involved. Sodium increases blood pressure, but it also causes insulin resistance. Iron even though an essential mineral, can impair the function of pancreatic beta cells. Nitrites and nitrates increase insulin resistance.
Some studies found that substituting other foods such as whole grains, nuts, fish, poultry and low-fat dairy for meat substantially lowered diabetes risk. A person with diabetes should consume Fruits, vegetables, whole grains and healthy proteins and totally avoid processed meat entirely.
