Aren't some chosen values that facilitate living "as something" harmful to our health (e.g. living as a smoker, a sculptor exposed to dust, an engineer in a sedentary job, etc.)?

Knowing it is not the best option for optimum health doesn't dictate your value of pursuing optimum health vs. enjoying the food you eat. If you found that optimum health could be obtained by only eating some synthetic goo, would you give up real food? I don't think you are evading rational and moral thought by taking a calculated risk with your diet.
