text: is there any food or tablet that contains all the essential vitamins, minerals and amino acids? ...for example is it possible to live on just spirallina and chlorella? nope. the reason is - we haven't yet discovered all the essential nutrients yet. let's take carotenoids, for example. science has found hundreds of new ones in just the last couple years and continues to find new ones regularly. our bodies are extremely complex systems which have evolved to eat a variety of foods from nature.  the best thing you can do to ensure you get what your body needs to be healthy is to eat a wide range of real foods. brightly colored fruits and vegetables are always good choices - color generally equals nutrients (with a few exceptions like cauliflower - no color but lots of vitamins and minerals).  also, you missed on thing - essential fatty acids. your body can't live or produce new cells without omega-3 and omega-6 fats.
