Wasting food isn't a good idea.  There are very few things that I'd recommend just throwing out, but there are many things you might have that you should simply never buy any more of.  You should warn members of your family that certain foods will become a thing of the past as soon as they run out.  However, don't make it a gloomy speech.  They'll readily get on board when you advise them that the family diet is going to become more natural, not less tasty or consciously calorie restricted.  You will be replacing your normal options with natural options, not depriving yourselves.

 

 

If you have any of the following in your kitchen, you should throw it away now, because it is either just poison, or has already turned bad, but you just don't know it because of misinformation:

 

These things you shouldn't throw away, but should be used mindfully until they run out, and then not be bought again:

 

These things you should take care about using in the future.  You don't necessarily have to absolutely eliminate them, but you should be using less of them over time.

Remember, these are guidelines, not really rules as yet.  A few things should be considered when clearing out your kitchen, and one of them is expense.  Another is practicality.  There are some places where many key natural foods are insanely expensive.  Part of the reason for this is because they are low demand and have to be bought in smaller lots.  It's also partly because they aren't subsidized, and are vulnerable to normal market forces.  In time, you will learn to "go with the flow" of nature and the market, but for now just use what there is.  How you eat is about to change anyway, and you will likely be spending less on groceries overall.
