As part of a government drive, the supermarket group's chief executive, Justin King, will this week share a platform with the public health minister, Caroline Flint, to discuss obesity in children.
An opinion poll has found that 71% of those surveyed believe that the cost of a drug or treatment should not affect whether or not it is given to NHS patients.
Health minister Caroline Flint has admitted that elderly people were still malnourished in some hospitals, in spite of government initiatives to ensure they received help during mealtimes.
