Just don't pull a Steve Jobs and become a Frutarian or whatever he calls it. Well balanced diet people. I think a lot of these tips are sort of presented in a "we found the solution" type way which is sort of misleading.

"An apple a day keeps the doctor away" is true to an extent. If someone eats a bowl of fruit without apple it's not like they missed the benefit. In fact, that apple might be worse for them at that point due to a higher fructose/carb intake.

I think a lot of these health tips need to be taken with a grain of salt. I mean, they found out fruit is good for you. That's about it. If you only eat fast food, drink soft drinks and sugary drinks, don't work out, and eat candy all day the benefits of replacing one of those terrible snacks for an apple is obvious.
