I absolutely love this post by The Healthy Home Economist and this post by Food Renegade. It includes links for where to buy such things as quality supplements, healthy cooking oils, meat & seafood, skincare products, etc. I use many of the products listed in these posts, such as zuzu makeup, primal pit paste deodorant, and coconut ghee.
If you're looking for vetted, quality products, or can't find what you need locally, I would start with this list!
If you're in the New Orleans area, I highly recommend Cleaver and Co. for sourcing quality, local, pastured meats. We get most of our pork products from here, as they have a good relationship with the farmers and ensure the pigs are raised humanely and are pastured. I was impressed to see that Rouses now carries local, grass-fed meat. Whole Foods is a good choice, too, but their meat products aren't usually from Louisiana and sometimes their selection of grass-fed or pastured chicken and beef can be limited. You can generally find gulf seafood in any store. We are lucky that gulf seafood is plentiful here and we can find gulf shrimp, fish, oysters, and lake crabs almost anywhere. I buy my shrimp from Rouses in the frozen section. Try not to eat imported or farmed shrimp or seafood which can be full of toxins, antibiotics, and isn't inspected properly. When you go out to eat, if the menu doesn't say "Gulf fish" or "Gulf seafood" it is probably imported and a bad choice.
Lamb is often a good choice anywhere you go, even if it's not local or doesn't specifically say organic or grass-fed, because lamb feed-lots don't exist, and much of the lamb products in stores are from New Zealand, where they are raised on pasture.
Kerrygold products (butter and cheese) can be found in many stores and comes from grass fed cows.
I've talked about Good Eggs before and I love it. I shop online for local products and have it delivered to my door! The selections varies by day, but I have ordered such things as butter, eggs, meat, fish, local honey, lettuce, vegetables, and prepared tamales. They have prepared foods, gifts, juices, baked goods and more. Update- they have scaled back and are no longer operating in New Orleans. I'm holding out hope they'll be back, though!
As you can tell, I have spent much of this post discussing meat and dairy products. That's because I believe that even though it can be expensive, you get the most bang for your buck buying local, grass-fed or pastured meat. The nutrition content is higher, you are avoiding added antiobiotics and growth hormones, and you're supporting traditional agriculture (real farmers) instead of corporations.
"In fact, more and more research is showing that cattle, pigs and poultry raised on their natural pasture and grass-based diets yield meat that is lower in total fat and calories, and food that is higher in good fats like Omega 3's, more concentrated with antioxidants such as vitamins E, C and beta-carotene, and with increased levels of other disease-fighting substances."
I buy organic vegetabes, generally from Whole Foods (I have found most organic veggies are actually cheaper at Whole Foods than Rouses!) but there are many veggies you don't need to buy organic. Anything with skin that you peel off generally has lower pesticide content, such as citrus, melons, onions, garlic, and avocados.
