Kale is a real superfood, but much cheaper than goji berries and chia seeds. By eating 125 grams of kale you achieve 90 per cent of the recommended daily amount of vitamin C and 350 per cent of the recommended daily amount of vitamin A. We always think fruit is packed with vitamin C. Still, kale contains much more vitamin C than the same weight of an orange.
Furthermore, kale contains a wide range of minerals like manganese, copper and calcium. Very usually kale is eaten in combination with something like potatoes or legumes. This means that the final total level of minerals and vitamins will be significantly higher.
