The authors of the study, called the Million Women study, said at the time that richer and more educated women in the study, who were more likely to buy organic food, also had risk factors that increase the likelihood of having breast cancer, such as to have fewer children and higher alcohol consumption.
The organic food market has grown in recent years, both in Europe and the United States. Organic food sales increased to $ 45.2 billion last year in the United States, according to the Organic Trade Association’s 2018 survey.
In order for food to be certified organic by the Department of Agriculture, products must be grown without the use of most synthetic fertilizers and pesticides and may not contain genetically modified organisms. The meat must be produced by rearing animals fed with organic food without the use of hormones or antibiotics. Such items now represent 5.5 percent of all food sold in retail, according to the organic trading group.
For research, researchers recruited 68,946 volunteers, who were 44 on average when the study began. The vast majority, 78 percent, were women.
The participants provided detailed information about how often they consumed 16 different types of organic food. The researchers asked for a wide range of foods including fruits, vegetables, dairy products and soy products, meat, fish and eggs, and cereals and legumes, bread and cereals, flour, oils and spices, wine, coffee and tea, biscuits and chocolate and sugar, and even dietary supplements. Study colleges gave three 24-hour protocols about their intake, including part-size, over a two-week period.
The information was much more detailed than provided by participants in the British Million Women study, which answered only a single question about how often they ate organic.
