Food is a great example of a situation where humans have found
themselves in a very new and quite potentially dangerous situation
as a result of ecological change.
In the hunter gatherer ecologies that humans are most adapted to,
humans ate a very diverse diet of vegetable
foods and meat.
In historic civil ecologies, most humans had diets with far less
diversity. If an agrarian group grew bread grains, that is what
they mostly ate.
Both groups periodically dealt with starvation.
Currently, not only do we have an incredible abundance of foods,
we have an incredible variety of all kinds of food. A technological
society is not likely to be food limited. The problem is this very
abundance. Humans are well adapted to a lack of food. Starvation has
always been an important limiting factor on all past human societies.
Partly in response to that, humans have a taste for high calorie and
high fat foods. Now we are betrayed by that instinct which in the
present ecology, can lead to dangerous situations of overweight and
obesity.
A Morality must be used to prevent a hazard from an instinct that was
an adaptation to a previous ecology. In ways it is very similar to
the natural adaptation to malaria, sickle cell anemia. It is a survival
traite in one ecology and a danger in another. In the case of food,
there will be natural and artificial genetic adaptation, but first
there will be behavioral adaptation.
The Greek word 'vegetas' basically means 'firm'. The Ancient Greeks
used the term to refer to unspoiled food and it was a philosophical
or moral concept that one should not eat rotted or spoiled food. It
was a somewhat novel concept at the time, but is a good illustration
of a concept or meme that has come to be part of very common
belief. It's reasons behind it's truth can be judged more accurately
now than it could be then, but that didn't prevent it from becoming
part of common moral law back then.
From that word has come the term vegetarian, though the original term
did not refer to eating a diet with no meat in it, as the term is
commonly meant today. Interestingly enough, it would not be particularly
surprising if at some future time, humans come to believe that eating
meat is novel or is as unacceptable as eating rotten foods. It could
depend on many things, including food availability and diseases.
Looking at technological development and the potentials of synthetic
foods, it could easily come to be that eating any naturally grown meats
or grain products could become considered strange.
Varying degrees of malnutrition have been the rule for humans rather
than the exception. The uninterrupted abundance of food associated with
the present technological society is a great novelty in history.
Some questions arise from that and an interesting moral concept.
The first question is what are the pluses and minuses of a modern diet?
Humans tend to be bigger with relitively weaker skeletons. At the same
time, modern diets certainly cut down on infant mortality and promote
better development of the brain.
As a minor question, is occasional food deprivation good for humans?
It does serve the purpose of allowing the intestines a break and an
opportunity to cleanse themselves.

A more interesting point is related to human 'rites of passage'.
The significance of rites of passage in all primitive societies
is well studied. When hypothesizing about characteristics of potenial
future moral methods, could fasting be used as a valuable rite of
passage in a technological society? Fasting is a behavior that triggers
hunger, a very basic physical response. It is going to a greater or lesser
extent act as a behavioral release. A rite of passage is to define a step
in maturity in the individuals society. Fasting could cause a behavioral
release that by itself could an important component of an individuals
maturity. It also could have a great validity in a "rich"
technological society with abundant food. The action of fasting, as part
of a common rite of passage, could be a useful element of a modern
moral system.
