It has been a while since I didn't shop in grocery stores. I only buy online for my personal skincare, but I go to the local market to buy vegetables and meat to cook. Fortunately, there is a store that sells whole food only walking distance from the house. Maybe you will like kefir.
We have been deceived by all the processed food found on the shelves in every air-conditioned market. I pity the children who eat hotdogs, canned goods, super sweet biscuits/cookies and junk food. They're all junk!
