Juices that can be found on shop shelves have not only been pasteurized, but also often contain unhealthy additives in the form of sweeteners or artificial flavors. Therefore, it is safer to prepare juices yourself and drink them immediately after pressing, so as not to lose the valuable substances contained in them. It is worth experimenting with fruit and vegetable smoothies that will contain fewer calories and simple sugars than those prepared from sweet fruits. The taste of a healthy smoothie will be fantastically enriched by beetroot, carrot, spinach, celery or parsley.
