Saturated fat does bad things inside the body every time you eat it. Eating foods that contain this bad fat every day over a period of weeks and years increases the risk of a lot of very unpleasant diseases. A little bit of saturated fat (16–20 grams) each day is OK, but most people eat a lot more than that.
Saturated fat comes mostly from animals. Any food that comes from an animal, such as beef, pork, salami, lamb, bacon, milk, cheese and butter, has saturated fat.
A small study in the Journal of the American College of Cardiology in 2006 found that a single meal high in saturated fat (e.g., a cheeseburger) can impair blood vessel function and decrease anti-inflammatory action of HDL (good) cholesterol. Another clinical study, in the journal Arteriosclerosis, Thrombosis & Vascular Biology, discovered that after only three weeks those subjects who ate a high saturated-fat diet suffered from a 50 percent decrease in their arteries’ ability to dilate to accommodate blood flow. Imagine what eating burgers, bacon, steak, cheese and ice cream does to your blood vessels if eaten several times a week or more.
