Intake of Repeatedly Heated Palm Oil Causes Elevation in Blood Pressure with Impaired Vasorelaxation in Rats

Repeatedly Heated Vegetable Oils and Lipid Peroxidation

“…The increased peroxide value of the heated oils may be associated with the significant increase in plasma lipid peroxidation. Chronic ingestion of heated oil was shown to cause an elevation of blood pressure [49] and necrotic cardiac changes [50]. This would disrupt the endogenous antioxidant defense in our body in order to overcome the overwhelming of oxidative stress.…”

A Short Review of Some Medicinal Plants And Phytocompounds With Hypotensive And Hypoglycemic Activities

“…Intravenous administration of dicentrine elicited a dose-related decrease in mean arterial pressure in anesthetized normotensive rats without affecting heart rate, cardiac output and stroke volume but markedly increasing tail blood flow [19].…”

“…Potentiation of peripheral and hepatic insulin sensitivity and reduction of intestinal glucose absorption were implicated in the mechanism of hypoglycemic action of the plant extract. Additionally, the extract might possess anti-atherogenic activity in view of its ability to elevate the ratio of high density lipoprotein-cholesterol to low density lipoprotein-cholesterol in the blood [18,19]. …”

Keloid of ear lobes: nature's ear rings

“…Polymers and polar compounds in the non-volatile products will remain in the oil (9). Heated frying oils were found to have higher content of free radicals compared to fresh frying oils (10). Deep-fried food contain free radicals as about one third of the dry weight of a deep-fried food is made up of oil absorbed during the process of deep frying (11).…”

“…They reacted with inorganic and organic chemicals (proteins, lipids and carbohydrates) particularly with the molecules in membrane and nucleic acids, thus producing a range of enzymatically damaging consequences (14). This would increase the risk of hypertension (10,15), atherosclerosis (16) and increased lipoprotein oxidation (17). The excess free radicals generated will also be detrimental to bone metabolism (18,19,20).…”
