Modern farming methods are blamed for the decline in minerals such as copper, iron, magnesium and potassium in fruit and vegetables.
Crops are being grown in soil stripped of its goodness. Vitamin loss could be exacerbated by fruits being picked before they are ripe.
They are often flown long distances before they actually hit the shelves and nutritionists say that fruit and vegetables which are fresh are more likely to contain the most vitamins.
Artificial fertilisers are used to speed growth and productivity of crops but this might not take account of the delicate balance of mineral requirements of plants and foods.
I would always personally suggest organic and GM free food to avoid these nasty extras! but this is not a debate over organic or not it's about the mineral content , organic does not always influence or increase the number of nutrients in the food just the lack of anything extra or harmful . Although more research needs doing on this over long periods of time,
We can’t blame the farmers and producers of our food it's a much bigger issue than this and more reflective of the face paced, profit and consumer driven world we live in.
