For half a century, vegetables were less useful
Fruits and vegetables today contain vitamins and minerals less than 50 years ago. Especially strongly decreased the amount of iron in them, calcium and vitamin C.
It is reported by the Swedish newspaper Svenska Dagbladet, citing the results of research the University of Texas at Austin. Using the base of the Department of Agriculture data US, the researchers analyzed the change in composition of 43 kinds of common fruits and vegetables between 1950 and 1999.
The results showed that during this period the content of vitamin C decreased to 15% phosphorous - 9, the iron - 15, calcium - 16, protein - 6, vitamin A - by 18. This means today wanting to enrich your body with vitamins need to eat four carrots instead of one. Scientists themselves have not yet made any findings. The main explanation for the observed phenomenon may be that breeders in the breeding of new varieties mainly pay attention to the increase in volumes of produced products, and not on the content of useful substances.
Swedish experts on nutrition has not yet been studying this problem. "Maybe it sounds strange, but we are not so well known, what is the amount of nutrients in our food, - he said responsible for the database of the Office of Food Irene Mattisson. - These tests are expensive, and allocated funds go to other studies.
