That's where I kind of disagree. A lot of the foods mentioned in the article, I've eaten and tried to cook at home. Many of the healthy grains (quinoa, amaranth, etc,) just taste really awful to me. However, I've also had some prepared by a talented cook who just has the skill levels I don't to make much of these taste good and still keep it healthy. I really don't have the time or patience to work on that. Unfortunately, some unhealthy foods taste pretty good without much effort so, there's where my problem lies when I'm in a crunch for time OR a crunch for the desire to cook and make it good.
This is where a personal chef would work for me.
