We’ve established that blueberries are good for us, but they are even healthier if they are grown organically.
Growing blueberries organically means no use of herbicide, pesticide, genetically modified inputs and chemical fertilisers. All products used are from natural sources.
A survey by the US Dept of Agriculture in 2002 showed that 73 percent of conventional crops contained at least one pesticide residue. Conventional crops were six times more likely to have multiple pesticide residues. Over 90 percent of conventional apples, peaches, pears, strawberries and celery were contaminated.
But research shows that organic fruit and vegetables actually have more nutrients than conventional.
In a study of organic versus conventional fruits, vegetables and grains, V Worthington showed that organic crops showed significantly more vitamin C, iron, magnesium, and phosphorus and significantly less nitrates than conventional crops. There were non significant trends showing less protein but of a better quality and a higher content of nutritionally significant minerals with lower amounts of some heavy metals in organic crops compared with conventional ones.
Organic certification is a process which assures the consumer that growing standards have been met.
