Quality of nutrition and diet is influenced by the consumer’s financial resources, reveals a study funded by the Swiss National Science Foundation. Some immigrants have a healthier diet than people born in Switzerland.
People with a higher level of education have dietary habits that are closest to the Mediterranean diet, which helps to prevent cardiovascular disease, diabetes and obesity. This is the conclusion of the study – the first of its kind in Switzerland – conducted by Pedro Marques-Vidal and his team at the CHUV (Centre Hospitalier universitaire Vaudois, Lausanne University Hospital).
The dietary habits of more than 4,000 inhabitants of Lausanne were evaluated in respect of three criteria. The first corresponds to the Greek Mediterranean diet, based on cereals, vegetables, fruit and fish. The second is a variant that includes dairy products, in order to reflect the habits of Swiss consumers. The third is an index of healthy diets, the “Alternative Healthy Eating Index”, which is used in the USA to evaluate the quality of nutrition of people with low incomes.
Lifestyle and country of origin
The study, forming part of the National Research Programme “Healthy Nutrition and Sustainable Food Production” (NRP 69), has found that the lifestyle of participants in the study influences their dietary behaviour. Those who are overweight, as well as smokers and people who lead sedentary lifestyles often eat less healthily. In contrast, older participants and those living together as a couple pay greater attention to the quality of their food.
Participants’ country of origin has also been revealed as a factor. “Despite occupying a relatively low socio-economic level, residents from Italy, Portugal and Spain have retained their Mediterranean dietary habits and eat more healthily than people born in France and Switzerland,” explains Pedro Marques-Vidal.
Action on prices
Other studies had demonstrated that less well-off consumers reduce the amount of healthy food they buy in favour of less expensive foodstuffs, which often provide lower nutritional quality. A higher level of education generally corresponds with more comfortable income levels, which allow consumers to buy more healthy foods.
According to research conducted in New Zealand and Australia, cutting prices is more effective in encouraging the purchase of fruit and vegetables than educational measures. According to Pedro Marques-Vidal, “special offers for fruit and vegetables that are reaching their sell-by date would be an example of a measure that could encourage changes in dietary behaviour.”
Studying the hearts of Lausanne
This research relates to the Lausanne Cohort (CoLaus), which studies the causes of cardiovascular diseases. Funded entirely by the Swiss National Science Foundation, CoLaus addresses the health and lifestyles of almost 7,000 inhabitants of Lausanne in order to develop new preventive and therapeutic measures.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
