Superfoods from manufacturer Diet Food is a category with foods that contain a high amount of biologically active substances. These are associated with positive effects on overall health, vitality and functioning of the body. Such beneficial substances include, for example, antioxidants, vitamins, minerals, and other biologically active compounds. To get your hands on superfoods, you don't even have to go out of your way. You probably already have them in your fridge or pantry. This is because blueberries, eggs, or sour cabbage also rank among superfoods. That said, each superfood contains slightly different beneficial substances, so it is optimal to combine them in different ways to maximize the intake of said substances.
