11 Feb 2019 --- Grocery store-based nutrition counseling is effective in changing the dietary habits of patients being treated for hypertension, a study published in the Journal of Nutrition Education and Behaviour has found. The researchers note that the location of the counseling may help to reinforce dietary changes as it is an environment where food decisions are made. Hypertension affects over 60 million adults in the US, yet less than half have their condition under control.
