Avocado Nutritional value
Avocados are high in valuable, health-promoting fats. For a typical avocado:
• About 75% of an avocado's calories come from fat, most of which is monounsaturated fat.
• Avocados also have 60% more potassium than bananas. They are rich in B vitamins, as well as vitamin E and vitamin K.
• Avocados have a high fiber content among fruits – including 75% insoluble and 25% soluble fiber.
• A fatty triol (fatty alcohol) with one double bond, avocadene (16-heptadecene-1,2,4-triol), is found in avocado.
High avocado intake has been shown to have a beneficial effect on blood serum cholesterol levels. Specifically, after a seven-day diet rich in avocados, mild hypercholesterolemia patients showed a 17% decrease in total serum cholesterol levels. These subjects also showed a 22% decrease in both LDL (harmful cholesterol) and triglyceride levels and 11% increase in HDL (helpful cholesterol) levels. Additionally a Japanese team synthesised the four chiral components, and identified (2R, 4R)-16-heptadecene-1, 2, 4-triol as a natural antibacterial component.
