Researchers analyzed information on over 13,000 people, a sub-sample of the widest epidemiological Moli-sani Project. Since 2005 this project has been recruiting about 25,000 adult subjects from the Molise region aiming to investigate the relationship between genetic and environmental factors in the onset of chronic disease such as cardiovascular disease and tumors. The authors explored the association between income and dietary habits of participants, evaluated according to specific scores of adherence to Mediterranean diet.
"We found that low-income people showed the poorest adherence to Mediterranean diet as compared to those in the uppermost group of income – says Licia Iacoviello, chairperson of the Moli-sani Project– In particular, high-income people have 72% odds of being in the top category of adherence to Mediterranean diet. This means a less healthy diet for the poorest, who are more likely to get prepackaged or junk food, often cheaper than the fresh foods of the Mediterranean tradition. In the lowest-income category we have recorded a higher prevalence of obesity as well. Low-income people report 36 % of obesity compared to 20% in the uppermost income class".
"Obviously we have considered all the possible confounding factors which may bias the observed effects – the authors say –The educational level, for instance, has a huge role in determining health status, as showed by previous studies. That is why we have further divided our population according to educational level but in this case too income appears to influence people's food choices".
I used to be too frugal when food shopping. Now I make myself buy the strawberries, dark grapes, cauliflower, and similar foods even when they are expensive in the winter. I buy large bottles of olives and use them in place of salt and other condiments.
