Purchase organic tomato passata/puree in glass containers (pure tomato without sugar or salt). Tomatoes are acidic which increases the rate at which BPA enters food and this can be a concern with canned tomato products. Tomatoes are a useful source of vitamin C, beta carotene, folate and potassium. Tomatoes are a nightshade vegetable.
About Susan Joy
I've battled with Chronic Fatty Liver Disease, an Autoimmune Thyroid Disease (Hashimoto's), Arthritis and digestive issues for many years. I decided to conduct my own research on what food choices could help my conditions. These choices culminate under what is termed a Paleo Lifestyle. I live in Perth, Western Australia with my husband of over 49 years. I'm the author of The JOYful Table cookbook, A JOYful Christmas, The JOYful Table 5-week Meal Plan and The Paleo Bread Cookbook.
