Less chemicals, better preparation procedures and more nutrient rich foods in your shopping trolley.
BUT Good food is expensive?? NO.... Shit food is CHEAP!
REMEMBER - you are making an investment in your health and I don't know of one single GOOD investment I made that was cheap!
Unless you're farming foods yourself expect to pay a little extra for high quality food sources... You wouldn't expect a meal in a nice restaurant to cost the same as a McDonald's would you?
There are always healthy alternatives to the food you are eating, get into a routine of buying the good stuff AND DON'T LET IT GO TO WASTE!!!
