Survey on Nutrition 50+

Demographic trends in Switzerland show that, owing to an increased life expectancy, the over-65 population group will continue to grow in the 21st century. A balanced, healthy diet is of vital importance for health and well-being in old age, in order to reduce the risk of various chronic diseases such as diabetes, osteoporosis and cardiovascular ailments. A survey of 632 individuals aged between 50 and 81 years was conducted to determine both the eating habits and behaviours and the nutritional knowledge of this demographic, as well as the frequency with which they consumed various foods, particularly those of animal origin. More on this topic can be found at the link below: 

Dairy products: requirements concerning
added fruit

The addition of fruit to dairy products can lead to food-safety risks. As part of a Bachelor’s thesis, an assessment was created for the evaluation and management of potential risks in order to reduce the likelihood of contamination to a minimum. The findings of the thesis are very important for smaller and medium-sized milk-processing establishments in particular, and are to be published as part of the InterLab sampling guidelines.

Absorption of carotenoids from spinach in humans

Leafy-green vegetables are a significant source of the carotenoids lutein and beta-carotene, both of which are important for sight. The findings of a recently concluded intervention study point towards lower baseline serum levels and poorer absorption of these carotenoids in short-bowel patients than in healthy individuals. Potential long-term effects on vision owing to malabsorption of these food constituents have yet to be elucidated.

Minimising pathogens on vegetables

The number of infectious diseases caused by the consumption of vegetables contaminated with human-pathogenic bacteria is on the rise worldwide. The location and potential absorption of such bacteria in vegetable plants as well as the role of input sources such as irrigation water are currently only partially clarified. In a current research project, Agroscope is investigating the colonisation of salad plants with enterohemorrhagic Escherichia coli (EHEC) in cooperation with the University of Hohenheim, Germany.
