Focus on the quality of meat, seafood and eggs you purchase. Stay away from industrially raised meat and seafood. Look for animals raised in a natural environment that aren't given growth hormones and antibiotics.

Check the labels carefully when buying meat/poultry. The USDA guidelines that allows companies to put "natural" on their label are not very strict. It basically means nothing was added after slaughter (no brine injected). Read report on Natural Grocers. According to the Jennie-O ground turkey label it is natural - contains no artificial ingredients and minimally processed. But this doesn't help with knowing how the turkey was fed and if it was given antibiotics or hormones. By the way, meat producers can put that it doesn't contain antibiotics if it wasn't given 60 days before slaughter. Harvestland states on their packages that there are no antibiotics - ever. Harvestland poultry might be a better choice. Let me know in the comments section if you have any suggestions for buying meat and poultry.
