An Avocado contains Phytonutrients, which are thought to help fight many diseases. The Avacado contain potassium providing balance of electrolytes and thwart cramps. Moreover, Avocado acts as a "nutrient booster" by enabling the body to absorb more fat-soluble nutrients, such as alpha- and beta-carotene, as well as lutein.

High in carbohydrates, Avocadoes are useful in the treatment of malnutrition, anorexic conditions and bulimia.

Avocado may be very beneficial for good heart health. The fruit contains healthy fatty acids, which help to reduce LDLs (the "bad" cholesterol), while increasing HDLs (the "good" cholesterol). Resarch in a V. A. Hospital in Florida have indicated that blood samples taken from those who ate avocadoes showed a definite decrease in serum cholesterol. This action works to improve circulation to the heart, brain and elsewhere in the body, as well as reduce hypertension Avocado may help meet the dietary guidelines set forth by the American Heart Association, which are to eat a diet that is low to moderate in fat, and the fats should be primarily unsaturated and low in saturated fat and cholesterol. Avocado is virtually the only fruit that contains monounsaturated fat. Furthermore, the high fiber content has been said to be helpful in achieving and maintaining good coronary health.

Avocadoes are a natural laxative for those in need of treatment for constipation. High Fiber from the Avacado may also contribute to a more regular functioning bowel movement.

The Avocado also contains beta-sitosterol, a phystosterol, which is considered beneficial toward prostate health. According to a paper presented by Dr. John Birkbeck, Professor of Nutrition at Massey University in New Zealand, the sitosterol has been used in the management of a variety of conditions, including benign prostatic hypertrophy, as carried out in a trial reported in the British medical journal, The Lancet, and in fact is the basis of drugs sold in Germany for this purpose. There is also evidence that phytosterols may reduce the risk of malignant prostate disease at least in animal models.

Avocadoes are a supply of lutein, a carotenoid, or pigment compound, which is also found in other green vegetables like spinach, kale and broccoli, and it is believed to support healthy eyes. The lutein content is said to filter or absorb cell-damaging, high-energy blue light from the visible light spectrum, which may protect human cells in the eye's retina.

High in vitamin E, vitamin A and lutein content, Avocado acts as an antioxidant, helping to reduce the harmful free radicals that can occur in cells and contribute to cell and tissue damage. The protective qualities that enable lutein to protect plant cells from sunlight and oxidative stress may also protect human cells in the skin and other organs and tissues from these same free-fradical damaging factors.

High levels of vitamin E used in the form of oil extracts in the Avocado contribute to promote moisture in skin thus the reason many of our ancestor’s use of this fruit to thwart aging effects of the sun and elements. There is some evidence that Avocado may be of some help in relieving symptoms of osteoarthritis when applied topically (see below for related article).

Further combating the ageing process, Avocado is said to help improve brain function. The reduces cholesterol and increased blood circulation not only helps to lower blood pressure but also improves blood flow to the brain, which is said to promote brain health, as hypertension is considered a risk factor for the decline in cognitive abilities.
