I'm new hear and trying to understand food labels. I understand how to use food labels. I understand the colour coding and the percentages , but I'm not sure if I'm reading them right. For example the fats and salt in some gravies and sauces are "high" ,but the colour coding is 3 greens and an orange for a 50 ml serving. Does that mean if I stick to the serving it is generally ok ? What is the best way to read all this stuff to make sure something is ok ?
