Throwing away the core is throwing away both food and the most beneficial part of the apple for your gut. Of the ~100 million bacteria in an apple, the core and seeds contain around 60%, while the pulp only contains around 20%, the skin 10%, the stem 10%. Numbers are from the top of my head, they could be off

Are you saying you eat Apple Cores?

[nsbk]

Yes, if you eat it bottom up instead of around, there is practically no core. Also much cleaner, and you just throw the stem away plus the benefit of ingesting all the good bacteria

It's actually not that hard if you change how you eat an apple. Don't eat around the core, and there won't be any core left at the end.
