Study summary: What happens to your body after one fatty meal?


    Study summary: What happens to your body after one fatty meal?

  • 1 Arteries become stiffer

    Your arteries have more trouble expanding. A 27% decrease in arterial compliance (see Point #2 for explanation) occurs after eating a fatty meal (67% of the calories are fat, around 50 g).

  • 2 What is arterial compliance?

    Arterial compliance is the ease with which the vessel wall expands with the change in blood pressure as the heart pumps the blood through the body. Impaired compliance puts people at a greater risk of carotid artery closure, stroke and death.

  • 3 What did the study subjects eat?

    A ham and cheese sandwich, buttered bread, whole milk and ice cream. Control group ate breads, breakfast cereal, fruit, low-fat milk, and spreads (10% calories were fat).

  • 4 How was the arterial stiffness determined?

    By ultrasound measurements over the ascending aorta and the right carotid artery.

  • 5 What changes occurred inside the body?

    Subjects who ate the 50 g fat meals, plasma triglycerides, remnant cholesterol and remnant triglyceride rose after 3 h and 6 h. Plasma total cholesterol, LDL cholesterol and HDL cholesterol were not on average altered. .

  • 6 What else can influence arterial stiffness?

    Arterial stiffness is closely related to age, blood pressure and diabetes. So bad diet is just one of the possible factors.

  • 7 Who did the study?

    The study 'Post-prandial remnant lipids impair arterial compliance' was done by Paul J. Nestel. It was published in the Journal of the American College of Cardiology in 2001.

  • 8 Graph

  • 9 Which food sources are considered fatty?

    Oil, cheese, cookies, fries, meat, grill, butter, chips, sausages, pizza and so on. Basically anything that has more than 15 grams of fat per 100 grams of weight can be considered a fatty food. See why we love pizza.

  • 10 Omega 3 can help

    Most of the fat in the food is Omega 6, which is pro-inflammatory. Omega 3, which are anti-inflammatory fatty acids can introduce balance into the system overloaded with Omega 6 (See Why is Omega 3 good for your health?).

  • 11 Reduce daily fatty food intake

    Humans can retain food in their digestive system for more than 24 hours. Carnivores retain the food in their system much shorter, for about 24 hours. Human body is not prepared to retain fatty food inside it for a long period of time and the daily buildup of fatty food causes issues.
