How does intake of unsaturated, saturated, and trans fats affect cholesterol levels in overall health?
Too much saturated, unsaturated, and trans fats and cause a person's LDL levels to increase. This could then lead to arterial hardening. If there is more LDL than HDL can uptake on, then a person could suffer from a heart attack or stroke. Unsaturated fats are called good fats because they can improve blood cholesterol levels, ease inflammation, stabilize heart rhythms, and play a number of other beneficial roles. Unsaturated fats are predominantly found in foods from plants, such as vegetable oils, nuts, and seeds. They are liquids at room temperature. Trans fatty acids, more commonly called trans fats, are made by heating liquid vegetable oils in the presence of hydrogen gas and a catalyst, a process called hydrogenation. Hydrogenation is used in restaurants and the food industry for frying, baked foods, and processed snack foods and margarines.
