Being sensitive to any with feelings, eat more healthy

As bivalves evolved from earlier creatures with brains, I think this should be considered much more. They all have nervous systems still. How can it be known that they would not evolve something else with the change such that they truly do feel things they are aware of, still. Having whole food from produce is not as costly as other things that might be chosen, the variety we can have from vegetables including leafy greens and legumes along with stalks, flowers, tubers, roots and bulbs counted among them, and whole grains, nuts, and seeds will help out health greatly.
