Take mayo for instance...three brands I loved because they are made with avocado oil have distilled vinegar. Have you read the ingredients? Distilled vinegar is made from corn. 90% of the corn produced is genetically modified. Most won't tell you the ingredients but here is a great article that explains.

What else did I learn?
Vegetable oil, all of them are made from soybean oil. Crisco is too. This is awful. Although I mainly use olive oil, many products I used have vegetable oil in their ingredients. My food choices are slowly being eliminated.
Salt is another ingredient that I am replacing. Table salt is bad for me. Table salt is processed and the minerals have been removed. In it's place I am substituting Celtic Sea Salt. I don't cook with salt and I don't sprinkle it on my foods but some Paleo recipes won't work without it.
I am back on Paleo. No more donuts at Tuesday morning Bible study. No more eating out. No more potlucks. It's time to work on making the rest of my life the best it can be. I am 73 years old but I don't have to deal with issues caused by my food choices. Sugar is hurting me and I don't have to let it control my life anymore.
Today I am making my own mayo. I am making my own ketchup. I am making my own products because I can control what I eat.
