Berries inhibit arteriosclerosis
Arteriosclerosis is a vascular disease in which crucial blood vessels gradually become less flexible and can transport less blood and, as a result, the risk of infarcts and strokes increases. According to a Norwegian experimental study, this process slows down if you eat more berries and other colored fruits.
That advice included that the subjects increase their intake of fresh fruit and vegetables. This was especially true for colorful fruit and vegetables, and in the first place for red and blueberries.
Using scans, the researchers determined to what extent the blood vessel walls - the carotids, to be precise - of the men became narrower over the three years. They also determined the effect of nutrition education by mapping the dietary patterns of the study participants.
Using scans, the researchers determined to what extent the mens's blood vessel walls - the vessel walls of the carotids, to be precise - became narrower over the three years. They also determined the effect of nutrition education by mapping the dietary patterns of the study participants.
In both the group that had received nutritional information and the control group, the condition of the vessel walls had deteriorated. The vessel walls of the carotids had thickened. But the extent to which this had happened was tens of percent less in the men who had started eating more berries than in the men who had not changed their diet.
"It is likely that vitamin C is a marker of increased fruit, berries and vegetables, foods that may influence atherosclerosis by a number of mechanisms", the researchers write.
