When the old food labels were designed over two decades ago, many people were deficient in vitamins A and C, which is why the amounts of those vitamins were required on the labels. Today, due to dietary changes, very few people suffer from vitamin A or C deficiency. On the other hand, research shows that people lack vitamin D and potassium in their diet. The new labels will require the declarations to show the actual amount and the recommended daily value percentage of vitamin D and potassium, to help fight micronutrient deficiency and improve diets.
