Nutritional value:
Avocados have diverse fats. For a typical avocado:
About 75% of an avocado's calories come from fat, most of which is monounsaturated fat.
On a 100 g basis, avocados have 35% more potassium (485 mg) than bananas (358 mg). They are rich in B vitamins, as well as vitamin E and vitamin K.[31]
Avocados have a high fiber content of 75% insoluble and 25% soluble fiber.[32]
High avocado intake was shown in one preliminary study to lower blood 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.[33] Additionally a Japanese team synthesised the four chiral components, and identified (2R, 4R)-16-heptadecene-1, 2, 4-triol as a natural antibacterial component.[34]
Due to a combination of specific aliphatic acetogenins, avocado is under preliminary research for potential anti-cancer activity.[35]
Extracts of P. americana have been used in laboratory research to study potential use for treating hypertension or diabetes mellitus.[36]

...from another site:
compared to other fruits, avocados have the highest Vitamin E content. Avocado oil's powerful antioxidant property protects circulating white blood cells, helping to keep the skin from oxidizing while it permeates through the cell wall.

Using the oil, which is NOT pressed from the seed as I erroneously suggested in the OP, it is pressed from the pulp of the fruit, also has some of the benefits and can be used in different manner than using the fruit pulp. Or would you possibly try to fry meat in avocado pulp? I'd rather use the oil

These would probably be found in the dryer areas of the map like badlands.
