Food quality: is organic better?

29 Oct

Efe raised the interesting issue of food quality on performance and weight management. This is my 1st swipe at the subject, and Im hoping others will help me find other studies.  We will take it for granted that many of our regular readers and visitors like organic and home grown ( yes, I know they can be different…..urban soil could be contaminated, blah, blah!), but to develop the debate we need to nail down actual studies, not un-reference E-books, aspirational wishing or well meaning blogs

Back in 2007 the daily mail ran this  story  “Organic food is healthier than conventional produce and may be better at preventing cancer and heart disease, according to the biggest study of its kind”

Read more:

I was interested at it mentioned a study  carried out by Professor Carlo Leifert, but in his profile, I cannot see any reference


A more up to date hatchet job is this clip taken from the NHS site (2009) which seems to hate organic food

an interesting, and more up to date  read is to be had at

Malene Søltoft, John Nielsen, Kristian Holst Laursen, Søren Husted, Ulrich Halekoh, Pia Knuthsen. Effects of Organic and Conventional Growth Systems on the Content of Flavonoids in Onions and Phenolic Acids in Carrots and PotatoesJournal of Agricultural and Food Chemistry, 2010; 58 (19): 10323

“On the basis of the present study carried out under well controlled conditions, it cannot be concluded that organically grown onions, carrots, and potatoes generally have higher contents of health-promoting secondary metabolites in comparison with the conventionally cultivated ones,” the report states.

  1. another hatchet job at

    Society of Chemical Industry (2008, August 7). Organic Food Has No More Nutritional Value Than Food Grown With Pesticides,

  2. Haven’t really come across any official studies on this area, but I have learnt that a farmer/grower doesn’t need to do much in order to label his/her food as organic and that very often the organic foods are marginally better than the standard ones, if at all, but the price is often significantly more.

  3. aggh, ofcourse. This should not be about proving organic good, it should be about assessing the impact of proceesed food.

    in which case, we all need to be aware of Pottenger’s Cats.

    according to some sales copy for his updated book

    “In his classical experiments in cat feeding, more than 900 cats were studied over 10 years. Dr. Pottenger found that only diets containing raw milk and raw meat produced optimal health: good bone structure and density, wide palates with plenty of space for teeth, shiny fur, no parasites or disease, reproductive ease and gentleness.

    Cooking the meat or substituting heat-processed milk for raw resulted in heterogeneous reproduction and physical degeneration, increasing with each generation. Vermin and parasites abounded. Skin diseases and allergies increased from 5% to over 90%. Bones became soft and pliable. Cats suffered from adverse personality changes, hypothyroidism and most of the degenerative diseases encountered in human medicine. They died out completely by the fourth generation.

    The changes Pottenger observed in cats on the deficient diets paralleled the human degeneration that Dr. Price found in tribes that had abandoned traditional diets”

    Perhaps, This is where we should start!
