I heartily endorse eating better food, including making trade-offs with time and/or money to do so. There can be little doubt that there's a trade-off between long term health and hedonic value of food as well, but certainly most of us are not at the frontier.

I would recommend also:

Step four: Be willing to throw food away.

A lot of people attach strong negative emotions to throwing away food, even if the food is no longer worth eating. Some of it is pure sunk costs, but often it goes beyond that and many people look upon it as a moral issue, or that it means somehow taking food away from someone else who needs it. It isn't one, and you're not.
