Can a nutrient deficit be balanced by a wholesome diet?
If a wholesome diet means a consistent and varied diet with foods with a high nutrient concentration, serious deficits will hardly occur. However, an existing nutrient deficit can hardly be compensated by a wholesome diet alone. As the magnesium example above shows, you would have to eat twice the quantity of foods containing magnesium daily for several months. An emphasis on this unbalanced, albeit wholesome, diet would certainly result in deficits in other nutrient supplies. Therefore, if nutrient deficits already exist, it is more efficient to take high-quality nutrient preparations in addition to a balanced diet.
