Avocado (Persea Americana Mill.) is a native fruit of Central and South America.[1]

Composition

Avocados are rich in fat (approximately 15% by wt.).[1:1]

Avocados contain predominantly monounsaturated fatty acids (MUFA; 9.6% by wt.), which represent 62.8% to 63.6% of the total fatty acids found in avocados, with a predominance of oleic acid.[1:2]

The oil consists of approximately 71% MUFAs, 13% polyunsaturated fatty acids, 16% saturated fatty acids, fiber, vitamin B, vitamin K1, vitamin E, magnesium, potassium, and phytochemicals such as carotenoids, phenolics, and phytosterols.[1:3]

Healing Properties

Antiinflammatory

Chronic avocado oil ingestion reduces C-reactive protein.[2]

Antioxidant

Avocado oil has a wide variety of lipophilic antioxidants, which may decrease ROS production in renal mitochondria.[1:4]

Blood Health

Chronic avocado pulp treatment improves anti-platelet and anti-thrombotic activities.[2:1]

There are acute benefcial properties of polyunsaturated and monounsaturated fatty acid from avocado on glycemic and vascular markers during an acute postprandial challenge in middle-aged, overweight or obese subjects.[2:2]

Cholesterol Levels

The high concentrations of MUFAs in avocado suggest that an avocado-rich diet results in beneficial effects on blood lipids.[1:5]

Chronic avocado oil ingestion reduced triglycerides and LDL and VLDL cholesterol.[2:3]

The inclusion of one fresh avocado per day in a moderately fatty diet supports an improvement in cholesterol levels.[2:4]

High Cholesterol (hypercholesterolemia)

8 weeks supplementation with avocado oil (450 and 900 mg/kg/day) partially improved the lipid profile (lower LDL and triglycerides and higher HDL) and increased the activity of the Krebs cycle.[1:6]

Antiobesity

Supplementation with hydroalcoholic extracts of the fruit (100-mg/kg body weight) for 12 weeks reduced weight gain (24.77%) and BMI (17.92%).[1:7]

Insulen sensitivity

Body weight reduction and improved insulin sensitivity were observed in rats fed a sucrose-rich diet and supplemented with 10–30% avocado oil for 8 weeks.[1:8]

Heart Health

Chronic ingestion of aqueous avocado leaf extract is benefcial in improving cardiovascular parameters.[2:5]

Blood Pressure

Chronic avocado oil consumption has beneficial effects on cardiovascular physiology, including lowered systemic blood pressure, reduced renal reactive oxygen species, improved renal endothelium-dependent vasodilation and kidney mitochondrial function, suggesting that avocado positively interacts with the angiotensin system in regulating blood pressure.[2:6]

Heart Disease

Atherosclerosis

Decreases the risk of atherogenic plaque formation.[1:9]

Exercise

Avocado pulp prior to aerobic exercise improves a number of cardiovascular and autonomic variables during recovery in healthy females.[2:7] This outcome supports the advantageous efects of avocado pulp prior to exertion, suggesting the benefcial use of avocado before exercise.[2:8]

Liver Health

Treatment with an aqueous extract of avocado (100 and 200 mg/kg) protects against hepatic toxicity.[1:10]

  • It reduces the activity of the liver enzymes aspartate aminotransferase and serum alanine aminotransferase and decreased serum bilirubin levels.[1:11]

Kidney Health

Chronic avocado oil consumption reduced renal reactive oxygen species, improved renal endothelium-dependent vasodilation and kidney mitochondrial function, suggesting that avocado positively interacts with the angiotensin system.[2:9]

Disease / Symptom Treatment

Diabetes

Helps control glycemia.[1:12]
