Fruits and vegetables
Self explanatory. Eat as many plants as you can.
nuts and seeds
Eat these raw, sprouted or soaked - avoid roasted. Nut butters are okay if it is raw and without added sugar. Nut milks are also cool if there are not any additives (check labels or make your own!) Canned coconut milk is a great unprocessed alternative.
The cleaner, the better. Factory farming and industrial scale production can contribute to all sorts of health problems, so the best quality meat you can afford to buy, the better (pasture raised, grass fed, etc). Any whole cut of meat, fish, or poultry is good. Avoid processed sausages, meats cured with nitrates, and the like. If you can't afford quality, stick with eggs, legumes, tempeh, and plenty of fresh vegetables - they are easy on the wallet and on your body.
Stick with the most minimally processed oils: olive oil and coconut oil. Ghee is also acceptable (clarified butter). Avoid canola oil, vegetable oil, soybean oil, safflower oil, and conventional butter.
Beans and Grains:
Dried beans and whole grains (with all parts of the grain intact) are not considered processed. Grains include quinoa, brown rice, bulgar, buckwheat, and rolled oats; beans include dried chickpeas, kidney beans, black beans, mung beans, etc.
-All sugar (including honey, maple syrup, agave)
-Processed meats (cured bacon, processed hamburger patties, etc.)
-Bread, pasta, and other processed grains (white rice, granola bars, etc.)
-Soy products (tempeh is okay)
