I think they have changed the saying to "an avocado a day keeps the doctor away.."
Apples give me acid reflux lol... j/k
It's interesting to note just how much diet can prevent a many number of health issues in certain ppl. Many ppl are also not aware of the various non life threatening food allergies they may have which yield symptoms.
Instead of also going straight for the prescribed drugs, some of which, fix one issue while inducing another, really taking a look at ones diet could end up being the most important & effective medicine of all.
