You have eaten a lot of it but perhaps don’t know what benefits it gives to your body. You’ve listened to a number of food experts and dieticians reeling out big nutritional clichés about it. But because you’re not familiar with the niche, you probably don’t get what is being talked about.

What about many of the popular television shows you have followed in the past, especially during the flu season? Or the amount of time you have spent in an elaborate education program about this fruit?

Summer is here on us, that time of the year when we showcase all we care about avocado. It is moment to unravel those myths and bring you detailed information you need to know about Avocado, arguably, the most beneficial and richest plants for nutritional, medicinal and health value.

In this fair, we’ve focused on avocado, a lively fruit in daily meals. You’ve got to live healthier, focus better, and have reason to be more active. There are a lot of programs out there young minds can participate in and be encouraged to eat more fruits and vegetables and practice a healthy, active lifestyle.

Exploring the world of Avocado?

Naively, many people classify avocados as green vegetables because it is commonly used in salads and because it has a savory vs. sweet flavor ; they are indeed fruits as they contains a tough outer layer, a fleshy middle, and a casing around a seed. Avocados are a global fruit and consumed in different various ways across the world. Avocado is the commonest tropical fruits. It contains fat soluble vitamins that many other fruits do not contain. It is an energetic fruit with high nutritional value. Avocados are fruits harvested from the avocado tree, scientifically known as Persea americana.

Avocado is a fruit incredibly high in protein, rich in potassium and unsaturated fatty acids. It also contains Vitamins A and B, plus average levels of vitamins D and E. Avocado pulp contains uneven oil content, and has been a raw material in many pharmaceutical and cosmetics industry. It is used in the commercial production of oils, similar to olive oils (Bleinroth & Castro, 1992).

Avocado tree and climatic conditions

The avocado tree, or alligator pear-tree’, as it is traditionally called, has a very high fruit yield, producing 138kg within 7 years of planting (Bleinroth & Castro, 1992). This evergreen tree is a biennial and perennial plant which can be grown on tropical rough locations, unlike the annual plants that germinate well on flat lands. Avocado trees have their own growth and germination conditions under which they survive. The main climatic requirements are temperature and rain fall. Although each variety of the fruit behaves differently based on their race, avocados, generally, which are known to be non-resistant to freezing temperatures, survive in tropical and subtropical climates. However, the Hass variety is developed to withstand freezing temperatures of about 31F, thus making it available for all year round.

How Avocado Trees Grow

At maturity, avocado trees can grow as tall as 65 to 80 feet and have the capacity to produce as many as 400 pieces of fruit within a year. The tree ¾if grown from seed¾starts to produce fruits between five to 20 years after planting. Avocado tree bears fruits every two years, making it one of the best biennial-bearing fruit trees.  Depending on the planting conditions including climate, soil, rainfall/irrigation, temperature/sunlight, care, etc., avocado tree can produce heavy crops in its bearing seasons. However, if not adequately and modestly furnished with good planting conditions, the tree may produce heavy crops in one harvest year and poor yields in the next.

Growers who want to see their avocado tree produce fruits within the first one year of planting often plant their commercial avocado orchards using the grafting method. Grafting consists of using grafted trees and rootstocks in which case the particular species to be planted is attached to another one, thus disallowing self-pollination. Today, most of the grafted, that is cultivars, are propagated without seed reproduction.

Harvesting Avocado fruit

Usually, avocado fruits fall off the tree and do not ripen on the tree. Large commercial avocado cultivators prefer (and this is the ideal method) picking unripe avocado fruits and ship them to store where they get fully ripe.

Growing factor Specifications
Soil Loose, decayed granite or sandy loam; well-drained; mulch layers
Temperature 60 to 80 F
Exposure Full sun; protected from wind
Irrigation Humid, Moist
Planting 10 feet (minimum) in all directions
Propagation Terminal or lateral grafting of seedling rootstocks
Harvesting Hand-harvest by clippers attached to poles

Races and Locations of Avocado

The Antillean race, the commonest of the avocado tree originates from the lowland regions of South and Central America. This race yields one of the largest fruits of piriform nature, with low oil content that is less than 8%. This race also prides in its high resistance to low temperatures, sustaining up to -2°C.

A Slice of History, production and consumption of Avocado

  • Avocado was originally named “agovago pears” after the tree ‘alligator pear-tree’ due to the fruit’s dark, stony membrane and pear-like shape. Later, it was later given the name “avocado” by Irish Sir Hans Sloane. The tree is native to tropics of Central and South America and the fruit has been used as food in Mexico and South America for centuries. The tree originated in Southern Mexico and Columbia circa 5,000 B.C.E.
  • By the middle of the 16th century, Spanish conquistadors who had travelled all the way to Mexico were handed avocados by the Aztecs and Incas upon their advent in Central America. However, by the start of the 19th century, avocados had found its way to southern Europe, as well as the Hawaiian Islands, Africa and Southeast Asia.
  • The introduction of the avocado tree in the United States was in mid 19th century (1833) by Judge Henry Perrine, and the tree landed in Florida.
  • By 1956, the tree was imported by Dr. Thomas White of the California State Agricultural Society from Nicaragua, California to Los Angeles, giving birth to the establishment of the California avocado industry as early as the 1870s. This was after the avocado trees brought from Mexico to Santa Barbara had produced fruits. 
  • In the United States, California, Florida, and Hawaii are states with the largest avocado cultivation. California grows more than 95 percent of American avocados.
  • Brazil stands 9th largest avocado producer, with 160,400 tons harvested in 2011 from 10,750 hectares of land. São Paulo state of Brazil is the largest producer with 47.5% production rate; it is followed by Minas Gerais with 19.0%, and Paraná, 11.2% (Almeida & Sampaio, 2013).
  • Production of avocado has increased globally due to advances in cultivation and harvest technologies, as well as decline in trade barriers, strong health related benefits, and increased incentives including land availability and in producing and potential countries
  • In Asia, Philippines, Taiwan and Indonesia take the lead in avocado consumption. The Philippines have a unique way of making and serving the avocados. The avocados are pureed with sugar and milk. Taiwan avocados are also served with milk and sugar. Indonesia follows similar form but consumers make the fruit into a drink and served with milk and coffee.
  • The United States produces 6% of the world’s avocado crop, ranking third behind Mexico and Chile. It is a staple fruit in America. Consumers are said to love the Hass variety of avocado because of its rich, creamy texture.

By-Products of Avocado

  • Avocado seed produces a number of by-products. The seed can be used in a number of ways but is largely generally underutilized.
  • The seeds represent a large segment of what makes the avocado fruit. While studies have shown that the avocado seed can serve as alternative to trim down the production cost of edible oil, the presence of toxic phenolic compounds is unhealthy.
  • The studies also indicate that the avocado seeds are a great feed for monogastric animals once there is extraction of phenolic compounds and ethanol.
  • Avocado leaves produce phytochemicals which come in the form of apigenin quercetin, rutin, orhamnetin, and luteolin, which serve as preventive substance against the progress of oxidative stress-related diseases. 
  •  The avocado leaves are good ingredients for pharmaceutical purpose, used to treat various diseases. They also come as teas in folk medicine.

Avocado Allergy Information  

No doubt, you can be allergic to avocados, but may not be as much as you find with peanuts or shellfish. They are basically two ways you can be allergic to avocados, namely, oral allergy and latex allergy.

  • Oral allergy occurs when you eat avocado and your body reacts to it as an invader. In that case, the body alerts your immune system resulting most times in itching of lips, mouth and throat.  Oral allergy to avocado could also be triggered if your body is naturally allergic to birch pollen.     
  • Latex allergy is triggered when your body is allergic to latex. It’s a cross-reactivity system which means that they contain similar amount of protein. Symptoms of avocado-latex allergy include lip swelling, sneezing, itching of the eyes,  vomiting, nausea,  stomach  

Managing avocado allergy

There are ways to go about managing symptoms of allergy to eating avocadoes either on your skin or in any part of your body. Avocado allergies are rarely severe.

  • See the doctor.
  • Use food-safe wash to clear off the pesticides and crop chemicals used either in planting or preserving the fruits
  • Choose organic avocados that are not exposed to these surface chemicals.
  • Test your skin for latex allergy
  • Use over-the-couter (OTC) antihistamine for mild symptoms
  • Use OTC cortisone cream for skin irritation
  • Avoid eating avocados if symptoms persist

How to slice, dice and peel avocados

  • Wash avocados before cutting to avoid bacteria and dirt from penetrating into pulp.
  • Use your paring knife from the stem part and gently press down it gets to the pit.
  • Seprate the two halves of the cut avocado by twisting in opposite directions.
  • Strike the pit side with your knife blade to get rid of the pit.
  • Slice the  flesh in horizontal and vertical rows
  • Gently invert the avocado to release the pieces.

How to prevent browning

Browning in avocado occurs when a part of the flesh is exposed to air or sun. This is because some chemical reaction must have taken place with the enzymes of the fruit. There are two or three methods, but the best one if the boil method. Your avocado can stay for several hours even in open air after boiling. 

  • Place your avocado into boiling water for exactly 10 seconds
  • Remove and transfer to an ice bath to cool.
