I've been eating an apple either for breakfast or as a snack for over a year now, mainly as a way to introduce fruit to my diet (otherwise it would be absent). I couldn't tell you that I feel better as a result, or that I'm measurably healthier, or even that I feel like I've eaten something afterwards. That's one of the points of snacks, is it not? To not be hungry for a little while? Since there's no real downsides, and it really is healthy, I'll keep doing it.
