There are very few natural, whole foods that we would consider "bad" to eat. If whole food is prepared in a way that preserves its natural nutrient composition, virtually all foods are good for you! It's usually what we do to foods that make them bad for us.

Here are some of the steps we can take to turn a good food into a bad food (don’t follow them though!):
* We can fry it in fat.
* We can over process it and destroy many of its nutrients.
* We can grow it in unnatural soil that has been treated with synthetic fertiliser or chemical additives.
* We can spray it with pesticides while it is growing.
* We can add synthetic chemical ingredients to it, like synthetic colours or flavours.
* We can add synthetic preservatives to it to extend its shelf life far beyond its natural shelf life.

Common examples of "good" foods turned into "bad" foods include:
* Whole grains that have been turned into 60% grain flours, in which the majority of original vitamins and minerals are lost along with removal of the bran and the germ.
* A whole fruit turned into a low-pulp or pulp-free fruit juice, with all of the pulp nutrients being lost from the juice.
* Nearly colourless, overcooked vegetables that have lost their vibrant greens and yellows due to excessive exposure to heat.
* Any prepackaged food that is a mystery in terms of its ingredient list and which contains more synthetic additives than whole food components.

In an ideal world we would all be eating organic food fresh from the farm!  We can only try!
