Narrowed vessels due to fast food

Fast food increases risk of heart attack and stroke

Burgers and fries are regularly on the menu of many people. Researchers at the University of Montreal recently found out how harmful fast food really is. According to your study results, greasy food leads to a severe narrowing of the vessels. The result: a significantly increased risk of diseases such as hardening of the arteries, heart attack and stroke.

Medium-sized foods good for the vessels Fast food may harm us much more than previously thought. An investigation by Dr. Anil Nigam, head of research at the Cardiovascular Prevention and Rehabilitation Center and visiting professor at the medical faculty of the University of Montreal, and his research team showed that fatty fast food resulted in a 24 percent narrowing of the arteries in the test subjects. For the study, the researchers had 28 healthy men - all non-smokers - between 18 and 50 years of age each eat a meal from the Mediterranean kitchen and a fast food meal every twelve hours.

The Mediterranean dish consisted of salmon, almonds and vegetables cooked in olive oil. 51 percent of the calories in this food consisted largely of monounsaturated fatty acids and polyunsaturated fats. As expected, this meal had a positive effect on blood lipid levels. They remained within the normal range for all study participants. The positive effect of the middle food diet was particularly evident in subjects with increased triglyceride values. "We believe that a Mediterranean diet is particularly beneficial for people with a high triglyceride level, such as patients who have metabolic syndrome, precisely because the Mediterranean cuisine could help keep their arteries healthy," said Nigam. Triglycerides are also known as neutral fats and make up the majority of the fats contained in the diet. Similar to cholesterol levels, an increased concentration in the blood can lead to arteriosclerosis (hardening of the arteries).

Fast food increases risk of cardiovascular diseases After twelve hours, the subjects ate a typical fast food breakfast, which consisted of a sandwich with desert, egg and cheese. Three röstis were served. Fifty-eight percent of the calories from this meal came from fats that were extremely rich in saturated fat and did not contain omega3 fatty acids. When the blood values ​​were measured two hours after the meal, it was found that the arteries of the study participants had narrowed by 24 percent.

Nigram, who carried out the study to examine the different effects of fast food and Mediterranean food on the so-called vascular endothelium, the cells belonging to the innermost wall layer of the vessels, said: “The result will hopefully change our daily eating habits. Poor endothelial function is one of the most important harbingers of atherosclerosis. ”(Ag)
