Products from animal agriculture are not essential for our health, as we should know. They are not even better for our health. Having whole foods without the processed stuff put into foods, with the food derived from plants, is the healthiest for us, with more of the variety of foods from plants being better, up to thirty that are different every week. Why have animal products? Those will not help coming close to that. So why continue traditions with use of animals when we can do better, with better ways not contributing to use and slaughter of animals that in our culture we would not permit to a dog?
