Question: Is it immoral to give away food that you regard as unhealthy? Assuming that one believes (as I do) that candy and sweets are harmful to health (especially in quantity), is it immoral to participate in trick-or-treat by giving children candy when they come to your door? Or, is it immoral to "dispose" of an unwanted gift of, say, a rich chocolate cake by leaving it by the coffee machine at work to be quickly scarfed up by one's co-workers (as an alternative to simply discarding it)? Is the morality of these two cases different because in one case the recipients are children while in the other case they are adults?

Question: What's right or wrong about calls for "moderation"? Many things are black and white, but sometimes moderation seems like the right course. For example, you don't want to stuff yourself full of every food that strikes your fancy, nor deny yourself foods that you enjoy. So you should eat moderately. Similarly, you don't want to agree to or deny every favor asked by a friend, but rather do some moderate amount. Is moderation a good guide in some areas of life?

Question: Since eating wheat is purported to be unhealthy due to gluten (and other stuff), is it immoral to eat bread? (Analogous to smoking being purportedly bad for you.) Since one has to eat something, it would be better to ask, "Is eating bread immoral when other food sources are available?"

Question: I have a friend who is pretty hardcore paleo and is often very critical of other people's diets. Food is really important to her and I don't think she means to sound so disparaging. How do I kindly tell her to butt out of mine and my friends' eating habits?
