Egg.

When Jesus said to feed lambs and sheep, it was not clear to all listening at that time, what He was meaning. He was aware some listening had ears and eyes shut to the profound meanings He preached so Mightily.
I try to be a veggie, but have indulged in fish not that long ago, for my health. Cheese is a favourite, but weigh it, as the cholesterol is a factor to consider wisely.
Far be it from me to rabbit on, about health when my example is less than holy as God knows. Yet an egg contains valuable nutritional ingredients some of which, ideally organic, support good eye health.
