Industrial methods of agricultural production have caused vegetables to contain less nutrients than before. This decrease, in some cases, is really important, according to a study from the University of Texas. After comparing the levels of thirteen nutrients since the year 1950, they observed that the amount of six of them had been significantly reduced in: proteins (6% decrease), calcium, phosphorus, iron (15%), vitamin B2 ( 38%) and vitamin C (20%). Everything indicates that the current and widespread chemical fertilizer that provides only a few substances accelerates the growth of plants but makes it difficult for them to acquire nutrients from the soil or through their own synthesis.
On the other hand, there are studies that show us that organic-produced vegetables, more respectful of the natural growth cycle of plants, contain more nutrients than industrially grown plants.
All this implies that, since vegetables contain less and less nutrients, we must increase their consumption or at least, supplement these deficiencies through food supplements.
