To the first point about the cost of eating healthy, we did some work in Edmonton. We went around and did calorie pricing of food items. We were particularly concerned and were motivated by the question, if you really were on a very tight budget and you first had to meet your basic energy needs before you could start worrying about nutritional concerns, what does the food landscape look like? We found that the energy cost of food varied by almost a hundredfold. If you were willing to eat a pile of sugar, you could meet your basic energy needs for under $1 a day, whereas if you insisted on trying to eat lean meat, such as turkey slices, you'd be spending $80 or $90 a day to get the same amount of energy.
These are very real tensions, very large differences that exist today in the relative prices of food when looked at by energy content, and that was not including luxury foods particularly.
On the second point...perhaps you could remind me.
