Can Food Prices Affect Glucose in Type 2 Patients?

Researchers examined the impact of the cost of healthy food for different income levels…. 

Researchers from the Economic Research Service, US Department of Agriculture, linked 1999-2006 National Health and Nutrition Examination Survey health information to food prices contained in the Quarterly Food-at-Home Price Database, to estimate the association between the price of healthy and less-healthy food groups and blood sugar among US adults with type 2 diabetes.

The results showed that the prices of produce and low-fat dairy foods were associated with blood sugar levels of people with type 2 diabetes. Specifically, higher prices for produce and low-fat dairy foods were associated with higher levels of glycated hemoglobin and fasting plasma glucose 3 months later. Food prices had a greater association with blood sugar for low-income people than for higher-income people, and in the expected direction.

The researchers concluded that higher prices of healthy foods were associated with increased blood sugars. Of the subjects followed, the increased blood sugars were especially pronounced among low-income people with type 2 diabetes.
