Organic Food No More Nutritious

S cientists 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.

Production of biofuels set to rise

The world’s production of biofuels is set to rise rapidly over the next ten years.

This is according to a new report by the United Nations Food and Agriculture Organization. The report stated that increased global demand for biofuels will “boost international trade” over the next decade. This is because of rising concerns about global warming and the search for alternative energies. Governments around the world are desperate to reduce the amount of fossil fuels they use so they can meet their CO2 targets. The current record price of oil is fueling the scramble for biofuels. New biofuel production plants are springing up in developed countries all over the world. The race is on to produce clean and economically-friendly biofuels that will provide up to 20 per cent of the energy needs in the major world economies.

Biofuels are not without their critics. Many people believe they are a major cause of the current rise in food prices. Industry analysts disagree and say biofuels make up only five percent of these increases, and that supply and demand is more to blame. However, it seems that a sharp rise in biofuel production would greatly influence food prices. This is because more wheat, seeds, palm oil and sugar would go into making biofuels instead of feeding people and farm animals. There is a danger that food riots could spread across the world, even to rich countries. People would have cheaper fuel for their cars but more expensive food on store shelves. This would greatly increase the gap between the haves and have-nots. In October 2007, a United Nations spokesperson called biofuels a "crime against humanity".
