Scientists have revealed that organic and non-organic food contain pretty much the same amounts and kinds of vitamins and other nutrients. This might be surprising news for those of us who choose to buy organic believing it to be healthier. Researchers from America's Stanford University concluded that there might not be any extra health benefits to buying organic, thus people might be better off saving their money and buying non-organic produce. Lead researcher Dr Crystal Smith-Spangle said there was no difference in the vitamin content in fruit, vegetables, meat and dairy products in organically- and conventionally-produced food. She said the only difference was slightly more phosphorus in the organic products.
Dr Smith-Spangle's review of over 200 different reports on organic food suggests people should perhaps revise their shopping choices, based on the levels of pesticides. Smith Spangler said both organic and conventional foods rarely exceeded the allowable limits for pesticides in the USA. She said the evidence wasn't too clear on whether the difference in pesticides would have an effect on health. She concluded by saying consumers should know there is overwhelming evidence that eating fruit and vegetables is good for your health, so people should eat more fresh produce, whether it is organic or conventional. Organic foods accounted for $31 billion in sales in the USA last year, up from $3.6 billion in 1997.
