Triglycerides used to express data such as physical examination results are simple lipids formed by fatty acids and glycerol.
Cholesterol is a derivative lipid.
Lipids can be divided into "fat" which is solid at room temperature and "oil" which is liquid.
The former is mostly found in the skin and fat of meat, while the latter is rich in fish and plant food.
Compared with the "visible lipids" such as salad oil and olive oil, most of the lipid foods people consume are still such "invisible lipids".
Balance nutrition in daily diet to avoid excessive intake of certain foods.
What substances are lipids made of?
Lipids can be decomposed to form substances such as cholesterol.
Triglyceride, wax, etc.
Simple lipids are composed of fatty acids and alcohols, which are mainly used as energy sources.
Fatty acids+glycerol form triglycerides, and fatty acids+higher glycerol form wax (a greasy compound).
Phospholipids, glycolipids, etc
It is a part of simple lipid and contains phosphoric acid and sugar.
Mainly as a component of cell membrane.
Fatty acid+glycerol+phosphoric acid forms phospholipids, and fatty acid+glycerol+sugar forms glycolipids.
Cholesterol, fatty acids, etc
Refers to compounds derived from or closely related to simple lipids or complex lipids. Including fatty acids as the main components of lipids, cholesterol that forms cell membranes, bile acids that promote digestion and absorption, etc.
Triglycerides are the source of energy for the body.
Excess triglycerides will be stored in the body as fat.
Most of the lipids contained in food are triglycerides.
Mainly as an energy source to provide sports energy for the body.
The remaining triglycerides will be stored in fat cells in the abdominal cavity and decomposed and utilized when needed.
Eating too much triglycerides can lead to fat accumulation and obesity.
In addition, sugar is also a component that forms triglycerides.
Meat and butter are rich in animal foods.
The fat content of pork belly is higher than that of tenderloin and breast meat.
Foods rich in triglycerides:
Precautions:
Basic substances for synthesizing cell membranes and hormones.
Cholesterol is a substance that synthesizes cell membrane, bile membrane, adrenocortical hormone and sex hormone.
It is transported to the whole body by low-density lipoprotein cholesterol, and the rest is recovered by high-density lipoprotein cholesterol.
Excessive intake of cholesterol cannot be completely dissolved in the blood. Excessive cholesterol will enter the blood vessel wall to form "plaque", leading to vascular stenosis and arteriosclerosis.
Animal liver, eggs, squid and so on are rich in cholesterol, and the use of bacon and other processed meat will increase the low-density lipoprotein in the blood, thus increasing the cholesterol value.
