Your pancreas is both and endocrine and exocrine organ. In English, this means that it has two main functions. It is responsible for the production of hormones and the production of secretions necessary for digestion. It is the pancreas that bears the brunt of diabetes.
To maintain good pancreatic function reduce your intake of sugary and refined foods. Eat less animal fats in favour of cold pressed virgin olive oil. Increase your intake of fibre as well by switching from white bread and pasta to spelt bread and whole grain organic pasta. Ask your practitioner about the value of minerals zinc and chromium which may aid in sugar cravings and enzymatic processes.
