Organic Nutritional Differences
"Ground-breaking new study finds clear nutritional differences between organic and non-organic milk and meat."
(Article by the Soil association - here).
The Soil Association has drawn attention to an important new study led by Newcastle University which was recently published (16 February 2016) in the British Journal of Nutrition. The team analysed data from around the world, reviewing 196 papers on milk and 67 on meat "and found clear differences between organic and conventional milk and meat, especially in terms of fatty acid composition, and the concentrations of certain essential minerals and antioxidants" (Newcastle University Site - here).
In their article, the Soil Association describes this significant study as involving "the largest systematic reviews of its kind" and providing clear evidence that:
"...organic milk and meat contain around 50% more beneficial omega-3 fatty acids than non-organic. In addition to organic milk and meat, the nutritional differences also apply to organic dairy like butter, cream, cheese and yoghurt."
Some of the Key findings cited in their article are outlined as follows:
* Both organic milk (dairy) and meat contain around 50% more beneficial omega-3 fatty acids than conventionally produced products
* Organic meat had slightly lower concentrations of two saturated fats linked to heart disease
* Organic milk and dairy contains 40% more conjugated linoleic acid (CLA) - CLA has been linked to a range of health benefits including reduced risk of cardiovascular disease, certain cancers and obesity, but evidence is mainly from animal studies
* Organic milk and dairy contains slightly higher concentrations of iron, Vitamin E and some carotenoids
Helen Browning, chief executive of the Soil Association, makes the following comment:
“This research confirms what many people have always thought was true -what you feed farm animals and how you treat them affects the quality of the food - whether it’s milk, cheese or a cut of meat. These scientists have shown that all the hard work organic farmers put into caring for their animals pays off in the quality of the food they produce - giving real value for money.
“Organic farming methods require all organic farmers to adopt techniques that guarantee nutritionally different foods. Following research in 2014 confirming nutritional differences between organic and non-organic crops like fruit and vegetables – we can now say for certain that organic farming makes organic food different.”
They suggest that the higher levels of Omega 3 is probably due to the difference in diet offered to organic cows:
"...organic animals have to eat a more natural grass-based diet containing high levels of clover. Clover is used in organic farming to fix nitrogen so that crops and grass grow (instead of manufactured/chemical fertilisers), and this research has found that clover also increases the Omega 3 concentrations in meat and milk. Under organic standards, organic cows must eat a 60% fresh grass based diet or hay/silage (conserved grass)."
This latest work builds on two previous published studies by the team at Newcastle University:
and an earlier study:
"Higher antioxidant and lower cadmium concentrations and lower incidence of pesticide residues in organically grown crops: a systematic literature review and meta-analyses" (here: British Journal of Nutrition / Volume 112 / Issue 05 / September 2014, pp 794-811).
From their findings, they conclude:
"This previous study – also published in the British Journal of Nutrition – showed that organic crops and crop-based foods are up to 60% higher in a number of key antioxidants than conventionally-grown crops and contained less of the toxic metal cadmium."
“We have shown without doubt there are composition differences between organic and conventional food. Taken together, the three studies on crops, meat and milk suggest that a switch to organic fruit, vegetables, meat and dairy products would provide significantly higher amounts of dietary antioxidants and omega-3 fatty acids,” (Professor Leifert).
