Junk Food Hurts Your Arteries, But Healthy Meal Might Help
WEDNESDAY, Oct. 31 (HealthDay News) -- Every junk-food meal you eat damages your arteries, while Mediterranean-type meals do no harm -- and may even have a beneficial effect, according to a new study.
Junk-food meals are composed mainly of harmful saturated fat, while Mediterranean-style meals are rich in good fats such as mono- and polyunsaturated fatty acids, according to the researchers from the Montreal Heart Institute, which is affiliated with the University of Montreal.
The study included 28 nonsmoking men who ate a Mediterranean-style meal first and then a junk-food meal a week later. The Mediterranean meal included salmon, almonds and vegetables cooked in olive oil. The junk-food meal included a sandwich made with sausage, egg and cheese, along with three hash browns.
