Importance Of Naringin For The Elderly

According to traditional Chinese medicine, grapefruit is sweet and sour in taste and cold in nature. It has the functions of strengthening stomach and transforming food, lowering Qi and eliminating phlegm, lightening body and pleasing color.? Modern medical research has found that grapefruit meat is very rich in vitamin C, insulin and other components, so it has the effects of reducing blood glucose, blood lipid, weight loss, skin beauty and volume. Regular consumption has an auxiliary therapeutic effect on hypertension, diabetes, vascular sclerosis and other diseases, and has the function of body building and nourishing for obese people.

Naringin (glucoside), citrus glucoside and isohesperidin are dihydroflavonoid compounds, which mainly exist in the peel and pulp of grapefruit, orange and orange in Rutaceae. They are also the main effective components of Chinese herbal medicine Drynaria, Fructus aurantii and orange red. Studies have shown that naringin has strong biological activities in antioxidant, hypolipidemic, antitumor, antifungal, anti atherosclerosis, analgesia, sedation, antispasmodic, regulating blood glucose and so on.

Dietotherapy：

1）. Antioxidant activity and myocardial infarction

The results of antioxidant activity and myocardial infarction showed that naringin could significantly reduce lipid peroxidation products and improve its antioxidant status by enhancing the activities of antioxidant enzymes and non enzymatic antioxidants.Many experiments have shown that naringin has strong antioxidant activity, which can reduce lipid peroxidation and protect by scavenging oxygen free radicals.

2)Antioxidant activity and ischemia-reperfusion injury

Reactive oxygen species play a causal role in renal ischemia / reperfusion injury, and naringin may play a protective role by scavenging free radicals and antioxidant activity., Naringin can significantly reduce the oxidative damage in cerebral ischemia-reperfusion injury group, which is manifested by reducing the concentration of lipid peroxidation and nitrite, restoring the activities of glutathione and catalase, and naringin can significantly improve the functional recovery after retinal ischemia-reperfusion injury.

3)Antioxidant activity and hypercholesterolemia

It was found that naringin could reduce the concentration of plasma hydrogen peroxide (H2O2) and lipid peroxide (LPO).

4)It has the function of scavenging free radicals and can reduce the damage caused by radiation。

Naringin has strong antioxidant activity and plays a beneficial role in a variety of cardiovascular diseases. It has been proved that naringin is a promising drug for the prevention and treatment of cardiovascular diseases.
