I don’t know if I can trust them, but I do read them. I’m talking about food labels on boxed and canned foods. From what I remember from school, every food product must have a food label in our country per the FDA.
When I’m food shopping, it can take a while since I read labels and compare ingredients of similar products. One example is beans for the chili I make. In the past I would use Red or Kidney Beans since the recipe called for them. Then over time I started to read labels and I found both Red and Kidney Beans had a retention agent included.
To avoid the retention and firming agents I started buying canned black beans. Most of the Black Beans are packed in water and salt only. At least at Meijr and Aldi where I shop. The other ingredient I avoid is corn syrup and reading labels helps me with this.
