An apple a day keeps a doctor away.

I think it is more of a proverb. If eating one apple a day kept you healthy then people probably wouldn't take vitamins.

Now adays nothing works,apart from an apple you should have a good diet food and good work outs to keep your body fit and healthy,i don't say apples are bad,they are good for health apart from that you need more nutrition too

I think that the proverb should be interpreted: an apple a day can contribute to keep the doctor away. This because you get a lot of vitamins eating fruit and this can improve your health. Of course, there's also another way to use the apple in order to keep doctors away, my father used to say... but this is the wrong way to use fruits, throwing them away. bye

I believe that apples are healthy. But nowadays I just found it difficult to buy delicious apples.
