New Study Reveals That Every Single Junk Food Meal Damages Your Arteries
One junk food - mainly composed of fat saturated - is harmful to the health of the arteries, while no damage occurs after consuming a Mediterranean cuisine served in good fats such as mono- and polyunsaturated fatty acids acids, according to researchers at the University of Montreal-Centre EPIC members of the Montreal heart Institute. Mediterranean food can even have a positive effect on the arteries. The results were presented at the Canadian Cardiovascular Congress, which runs in Toronto until Wednesday by the head of the study, Dr. Anil Nigam, director of research at the Center for Cardiovascular Prevention and Rehabilitation (EPIC) and associate professor university School of Medicine.
good fat vs. bad fat
Dr. Nigam conducted the study to compare the effects of junk food and typical Mediterranean food on the vascular endothelium: the inner lining of blood vessels. By measuring endothelial function, it is possible to determine the ease with which the arteries dilate after the temporary occlusion five minutes after consumption of the two types of meals. This is a very interesting for researchers as to perform analysis endothelial function is closely linked to the long-term risk of developing coronary artery disease.
The study also found that participants with the highest levels of triglycerides in the blood seemed to benefit more of the healthy foods. Their arteries responded better to the Mediterranean meal compared to people with low levels of triglycerides. "We believe that a Mediterranean-type diet may be particularly beneficial for people with high triglyceride levels, such as patients with metabolic syndrome, precisely because it could help maintain healthy arteries," said Dr. Nigam.
Mediterranean food versus food junk food
the results were established in 28 nonsmoking men who ate the food of the Mediterranean first type and then trash type of food meal a week later. Before you start, men ultrasound underwent ulnar artery at the elbow crease after fasting for 12 hours to assess their baseline endothelial function. The researchers then tested the effects of each meal. The first was composed of salmon, almonds and cooked in olive oil, vegetables, of which 51% of total calories came from fat (fatty acids mostly monounsaturated and polyunsaturated fats.) The second meal consisted of a sandwich made from a sausage, an egg and a slice of cheese and three hash browns, for a total of 58% of total calories from fat: rich in saturated fatty acids and contains omega-3. In two hours and four hours after each meal, participants underwent further ultrasounds to assess how the food had impacted their endothelial function.
Dr. Nigam and his team found that after eating junk food meal, the arteries of the study participants dilated 24% less than they did when in the fasting state. In contrast, it was found that the arteries to dilate normally and maintain good blood flow after Mediterranean food. "These results are positively alter the way we eat daily. Poor endothelial function is one of the most significant precursors of atherosclerosis. Now it's something to think about at every meal," said Dr. Nigam.
