Organically grown foods...big rip off?

I often thought it was a merchandising scheme. The Yuppies and nouveau riche bought it.

"Organic food no better for vitamins and nutrients, suggests US study"

Organic produce no more nutritious than regular food, say researchers, but it does generally reduce exposure to pesticides

Organic produce and meat typically is no better for you than conventional food when it comes to vitamin and nutrient content, although it does generally reduce exposure to pesticides and antibiotic-resistant bacteria, according to a US study.

Crystal Smith-Spangler, who led a team of researchers from Stanford University and Veterans Affairs Palo Alto Health Care, reviewed more than 200 studies that compared either the health of people who ate organic or conventional foods or, more commonly, nutrient and contaminant levels in the foods themselves.

The foods included organic and non-organic fruits, vegetables, grains, meat, poultry eggs and milk.

According to US department of agriculture standards, organic farms have to avoid the use of synthetic pesticides and fertilisers, hormones and antibiotics. Organic livestock must also have access to pastures during grazing season.

However, many of the studies used did not specify their standards for what constituted "organic" food,, the researchers wrote in the Annals of Internal Medicine.

Smith-Spangler and her colleagues found there was no difference in the amount of vitamins in plant or animal products produced organically and conventionally – and the only nutrient difference was slightly more phosphorous in the organic products.

Organic milk and chicken may also contain more omega-3 fatty acids, but that was based on only a few studies.

More than one-third of conventional produce had detectable pesticide residues, compared with 7% of organic produce samples. Organic pork and chicken were 33% less likely to carry bacteria resistant to three or more antibiotics than conventionally produced meat.

Smith-Spangler said it was uncommon for either organic or conventional foods to exceed the allowable limits for pesticides, so it was not clear whether a difference in residues would have an effect on health.

But others said more research was needed to fully explore the potential health and safety differences between organic and conventional foods, and it was premature to say organic foods were no healthier than non-organic versions.

"Right now I think it's all based on anecdotal evidence," said Chensheng Lu, who is studying environmental health and exposure at the Harvard School of Public Health.

Organic foods...no better

Now science has offered an opinion regarding organic foods...no better and marginally nutritional as its counterpart. Was this nothing more than a marketing ploy?

"Organic food is no healthier, study finds"

LONDON--Organic food has no nutritional or health benefits over ordinary food, according to a major study published Wednesday.

Researchers from the London School of Hygiene & Tropical Medicine said consumers were paying higher prices for organic food because of its perceived health benefits, creating a global organic market worth an estimated $48 billion in 2007.

A systematic review of 162 scientific papers published in the scientific literature over the last 50 years, however, found there was no significant difference.

"A small number of differences in nutrient content were found to exist between organically and conventionally produced foodstuffs, but these are unlikely to be of any public health relevance," said Alan Dangour, one of the report's authors.

"Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority."

The results of research, which was commissioned by the British government's Food Standards Agency, were published in the American Journal of Clinical Nutrition.

Sales of organic food have fallen in some markets, including Britain, as recession has led consumers to cut back on purchases.

The Soil Association said in April that growth in sales of organic products in Britain slowed to just 1.7 percent in 2008, well below the average annual growth rate of 26 percent over the last decade, following a plunge in demand at the end of the year.
