一項研究顯示:有機牛奶中維他命的含量遠比非有機牛奶高的多。
Drinking organic milk has more health benefits than drinking non-organic, a study has suggested.
The research was presented to the Soil Association's annual conference in Newcastle.
It showed organic milk has higher levels of vitamin E, omega 3 essential fatty acids and antioxidants, which help beat infections.
But nutritionists said people who drank non-organic milk would be getting these nutrients from other sources.
Grazing space
The research was carried out by a team from the Danish Institute of Agricultural Research, which is part of the University of Newcastle's Quality Low Input Food (QLIF) Congress.
Milk was tested from cows who were farmed organically and conventionally.
The study found cows farmed organically produced milk which was, on average, 50% higher in Vitamin E than conventionally produced milk.
Organic milk was also 75% higher in beta carotene, which is converted into Vitamin A in the body.
It was also two to three times higher in the antioxidants lutein and zeaxanthine.
Antioxidants are the naturally occurring substances in plants that protect the body from free radicals - 'bad' chemicals in the blood.
Free radicals alter cholesterol in a process known as oxidation, which is thought to speed up the hardening of the arteries.
Higher levels of omega 3 essential fatty acids, which are believed to help provide protection from coronary heart disease, were also found in organic milk.
The study concluded that drinking a pint of organic milk a day would provide 17.5% of the required daily intake of Vitamin E for women, and 14% of that for men.
The researchers suggest it also provides as much beta carotene as a portion of vegetables, such as brussel sprouts.
They say organically-reared cows benefit from having more room to graze than conventionally-reared cows.
