No reason. I'm making a point about a few things:
1. cost. people ignore the cost of living this lifestyle. don't forget to add the real costs of it, including the pills. As far as I can tell, animal products are the most efficient, in terms of consumer price, delivery system for the essential fats, proteins, and B12.
2. the state of health knowledge and education. It's fine to advocate this, but it has real effects and those real effects are that even smart people like me will think, Oh hey, I can only afford beans and rice anyone, and everyone says it's healthy. Then you get sick. I was very ill from eating this way a few years ago, primarily because I simply can't live on a carb-based diet. my body can't take it. It makes me sick and affects my liver's ability to manage cholesterol production. Not surprisingly, I'm waking up pretty regularly to find that my heart stopped in my sleep. That's the damage that results from eating a diet that's fine for calories but insufficient in terms of what i need to live -- and having my particular heart condition.
3. human practice. And people who are sick and need meds are so good at taking their meds. The likelihood that people will take their vitamins regularly may be an issue. As Deb pointed out re: living on food stamp diet, food stamps don't pay for your vitamins. Most poor people won't find the money to afford them, either, since 1. people don't like pills and 2. people don't realize how important they are.
singer's claims are interesting, but to effectively bring them about requires a lot more than individuals sitting around making 'ethical' decisions on the basis of what some philosopher claims about what it means to lead the ethical life.
e.g., perhaps all of thie becomes common knowledge and everyone thinks the state of the world will be much improved were we to follow his plan. What costs are associated with _that_ -- to make it happen, for instance.
Just thoughts.
