Technical Field
The invention belongs to the technical field of preparation of functional health-care foods, and particularly relates to a pecan oil composition with a blood fat reducing function and a preparation method thereof.
Background
Hyperlipidemia refers to the condition of high blood cholesterol (TC) and/or Triglyceride (TG) or low high density lipoprotein cholesterol (HDL-C), and is called dyslipidemia in modern medicine, is the most main risk factor of cardiovascular diseases caused by systemic diseases, often causes complications of organs such as heart, brain, kidney and the like, and seriously harms the health of human beings. Its direct damage is the acceleration of systemic atherosclerosis, and it is known that important organs throughout the body are supplied with blood and oxygen by arteries, which can have serious consequences once the atheromatous plaque is blocked.
In addition, arteriosclerosis also causes renal failure. A large number of research data show that hyperlipidemia is an important risk factor for cerebral apoplexy, coronary heart disease, myocardial infarction and sudden cardiac death.
Referring to cardiovascular disease, many people are known to be associated with hypertension, but in fact, hidden in our bodies, there is a more concealed, more serious "killer" that is hyperlipidaemia that is threatening our vascular health at all times. Experts point out that dyslipidemia is one of important risk factors for cardiovascular and cerebrovascular diseases such as coronary heart disease, myocardial infarction, ischemic stroke and the like. Patients with hyperlipidemia must be found and treated early. Therefore, the understanding of hypertension is improved, and the Chinese medicinal composition has extremely important significance for early prevention and timely treatment. The modern medicine for treating hyperlipidemia generally has the following sequence: the food therapy, the tea therapy, the health care and the traditional Chinese medicine are finally selected by western medicines which are not very useful. In order to control hyperlipidemia, various methods have been devised in addition to taking medicines.
