Unhealthy food isn’t immediately hazardous. Even if unhealthy food is not naturally digestable. We’ve been conditioned to digest foods that shouldn’t naturally be consumed (example: cow’s milk for adults), haven’t we? The only thing that confuses me about this subject is how do animals know what not to eat? If they eat something that disagrees with me, then they learn not to eat it again. But for poisons… do they just die? Do they learn from other animals? Haven’t some animals built up an immunity to certain things? Animals choose favourite foods too, right?
