Food manufacturers over the last nearly 100 years have progressively added more and more refined sugar and salt to our food to the point that many people are no longer able to enjoy natural food. If you restrict your food variety you are also restricting the nutrients your body can access.
Different foods contain different nutrients and particularly trace minerals. One of the most amazing nutrients is Selenium. It is deficient in Australian soil, but if you eat South American Brazil nuts they are a magnificent source. Raw Broccoli is a fantastic source of Co-enzyme Q10 which is renowned for its ability to generate cellular energy. It powers the batteries of your cells, the mitochondria. Natto is another sensational food that is a great source of vitamin K2 and helps repopulate the intestinal flora and transport calcium.
