Buying organic produce means that it is grown without pesticides, insecticides and herbicides.  Below is a list of when you should buy organic produce (most contaminated) and a list of when it is not always necessary to buy organic (least contaminated). Of course when it comes to availability, if organic is not available, then it is better to buy conventional than nothing at all.  In this case you can wash conventional produce with some diluted apple cider vinegar and scrub the outer skin with this mixture. This will help to remove any pesticide on the outer layer of the produce, although keep in mind that pesticide is still absorbed through the skin and therefore can still be found inside.

When it comes to dairy, eggs and meat, it is best to buy organic. This means it has been raised with a restricted diet, Bovine Growth Hormone Free (rBGH), antibiotic free and vegetarian fed.
