Is organic food more nutritious?
More nutrients and less water
Artificial fertilisers increase the water content of fruit and vegetables. Although this method may produce bigger yields, it dilutes the nutrient content of fruit and vegetables.
More minerals and more vitamin C
Research comparing the nutrient contents of organic and non-organic fruit and vegetables reveals a strong trend toward higher levels in organic produce. Of 27 valid comparisons of the mineral and vitamin C contents of organic and non-organic crops, 14 showed significantly higher levels in organic produce while just one favoured non-organic.
More protective antioxidants in organic produce
Plants contain some 5,000-10,000 naturally occurring compounds (known as phytonutrients) that are often involved in protecting the plant from pests and diseases. Because organic crops are not artificially protected with pesticides they tend to produce more naturally occurring phytonutrients, many of which are now known to have protective (antioxidant) properties. Some are proving useful in the prevention and treatment of cancer.
