Refined carbohydrates like white bread should be one of the first thing you avoid if you have pancreatic cancer. Excess taking of these refined carbohydrates leads to release of large amounts of insulin in the body. The work of pancreas is to regulate blood sugar levels in the body and if large amounts of insulin is released in the body, that will be a problem. The pancreas will be overworked and it will cause a lot of discomfort and can even lead to death. This is why you should avoid refined carbohydrates at all costs if you have pancreatic cancer. Instead of taking refined carbohydrates try taking whole grains which will at least have some positive impact to your health.
