text: from an evolutionary standing, why don't the healthiest foods taste good? unhealthiest taste bad?   you like the bad-for-you stuff because back in the hunter-gatherer days storing fat was very desirable. you didn't know where your next meal was coming from. it's a reward pathway built into the brain.  now food is easily accessible and we don't have to worry about it, but high-energy-content foods like fats and sugars are still very desirable from the body's standpoint because it's always looking to store up for the future.
