There is a lack of clear medical evidence that onions lower blood lipids. Onions belong to the food, and can not replace the efficacy of the drug.
Onion lipid claims are exaggerated, the basis of this claim is that onions contain flavonoids, flavonoids have the ability to improve the body’s antioxidant capacity, scavenging free radicals, which is conducive to the body’s anti-aging and can maintain the normal permeability of the blood vessel wall, remove the cholesterol adhering to the blood vessel wall.
However, the amount of flavonoids contained in onions is extremely limited, and there is no clear clinical data to show that eating onions can reduce the level of blood lipids in the blood. Moreover, onions are irritating to the mucous membranes, and consuming large quantities of onions may trigger oral, gastrointestinal discomfort.
Therefore, eating onions can not be used as a method of lipid-lowering treatment, hyperlipidemic people still need to follow the doctor’s instructions to take oral lipid-lowering drugs, pay attention to low-fat dietary habits.
