Saturated fat是什麼意思
"Saturated fat" is a type of dietary fat that is found in both animal and some plant foods. It is called "saturated" because it contains only saturated fatty acids, which are fats that are solid at room temperature. These fatty acids are typically found in foods that come from animals, such as meat and dairy products, as well as in tropical oils like coconut oil and palm oil.
Saturated fats are known for their ability to raise levels of low-density lipoprotein (LDL) cholesterol in the blood, which can increase the risk of heart disease. For this reason, most dietary guidelines recommend limiting intake of saturated fats and replacing them with unsaturated fats, which are typically found in foods like nuts, seeds, avocados, and olive oil.
However, the relationship between saturated fat consumption and heart disease is a complex one, and some recent research has suggested that the overall dietary pattern may be more important than individual nutrients like saturated fat. Some studies have also suggested that not all saturated fats may be equally harmful, and that the source of the fat may be important. For example, some research has suggested that saturated fats from dairy products may have different effects on heart disease risk than those from meat.
