Low sodium diet for gastric cancer prevention in the United States: Results of a Markov model.

Using a Markov model of gastric cancer risk, we found that adherence to a low sodium-DASH diet could decrease the risk of gastric cancer. This intervention was not cost-effective due to the high cost of a low sodium-DASH accordant diet, but significantly improved for high-risk populations and when the cost of the diet became slightly more affordable.
