Avocado facts and health benefits

 

Avocado scientifically known as Persea Americana is a tree which is native to Central America and Mexico and classified in the flowering plant family Lauraceae. The word “avocado” is said to be derived from the Nahuatl word “ahuacatl”, which means “testicle”. Obviously, it describes the fruit shape and likely refers to the potency of avocado, which is supposed to be aphrodisiac. Apart from Avocado it is also known as Alligator Pear, Alligator Pear, Avocado, Avocado Pear, Butter Pear, Guatemalan Avocado, Lowland Avocado, Mexican Avocado, Midshipman’s Butter, Trapp Avocado, Vegetable Marrow, and West Indian Avocado. Avocado is rich in monounsaturated fats, which make its texture creamy and smooth. Compared to most other fruits, avocado is much higher in fat. Avocados are called climacteric fruits because they only ripen after harvesting, just like bananas.

Plant

The avocado is an erect, dense, evergreen, medium tree, shedding many leaves in early spring. It is fast growing and is 10–12 m tall and may reach 20 m, and generally branches to form a broad tree. Some cultivars are columnar, others selected for nearly prostrate form. One cultivar makes a good espalier. Growth is in frequent flushes during warm weather in southern regions with only one long flush per year in cooler areas. Roots are coarse and greedy and will raise pavement with age. Grafted plants normally produce fruit within one to two years compared to 8 – 20 years for seedlings. They normally thrive and perform well in climatic conditions ranging from true tropical to warmer parts of the temperate zone. They prefer loose, decomposed granite or sandy loam. They will not survive in locations with poor drainage. The trees grow well on hillsides and should never be planted in stream beds. They are tolerant of acid or alkaline soil. In containers use a planting mix combined with topsoil. Plastic containers should be avoided. It is also useful to plant the tub with annual flowers to reduce excess soil moisture and temperature. Container plants should be leached often to reduce salts.

Foliage

Avocado leaves are alternate; petiole 2–5 cm, sparsely pubescent. Leaf blade is simple, variable in shape, narrowly elliptic, elliptic, ovate, or obovate, 8–20 × 5–12 cm, usually somewhat glaucous lower surface, deep green above, leathery, sparsely yellowish brown pubescent above but very densely so below when mature, midrib conspicuously raised below, lateral veins 5–7 pairs, distinctly raised below, slightly elevated above, base cuneate or acute to sub rounded, apex acute, margin entire. The leaves are high in oils and slow to compost and may collect in mounds beneath trees.

Flowers

Avocado flowers appear in January – March before the first seasonal growth, in terminal panicles of 200 – 300 small yellow-green blooms. Flowers are yellow-greenish; 5–6 mm on 6 mm densely yellowish brown pubescent pedicels. Each panicle will produce only one to three fruits. The flowers are perfect, but are either receptive to pollen in the morning or shed pollen the following afternoon (type A), or are receptive to pollen in the afternoon, and shed pollen the following morning (type B). About 5% of flowers are defective in form and sterile. Production is best with cross-pollination between types A and B.  The flowers attract bees and hoverflies and pollination usually good except during cool weather. Off-season blooms may appear during the year and often set fruit. Some cultivars bloom and set fruit in alternate years.

Fruits

Fruit  is normally yellow-green, deep-green or very dark-green, reddish-purple, or so dark a purple as to appear almost black, and is occasionally speckled with tiny yellow dots, it may be smooth or pebbled, glossy or dull, thin or leathery and up to 6 mm thick, pliable or granular and brittle, large, usually pear-shaped, sometimes ovoid or globose, 8–18 cm; exocarp corky; mesocarp, bright-green fleshy, but generally entirely pale to rich-yellow, buttery and bland or nutlike in flavor. The flesh of avocados is deep green near the skin, becoming yellowish nearer the single large, inedible ovoid seed. The flesh is hard when harvested but softens to a buttery texture. Off-season fruit should not be harvested with the main crop, but left on the tree to mature.

The single seed is oblate, round, conical or ovoid, large, 5–6.4 cm long, hard and heavy, ivory in color but enclosed in two brown, thin, papery seed coats often adhering to the flesh cavity, while the seed slips out readily.

History

The avocado originated in south-central Mexico between 7,000 and 5,000 B.C. This wild avocado tree was not domesticated until several thousand years later. Domesticated avocado seeds have been found buried with Incan mummies dating back to 750 B.C. and avocados may have been cultivated in Mexico around 500 B.C. Spanish conquistadores in central America could not pronounce the Aztec word ahuacatl, so they changed it to aguacate. Sir Henry Sloan first mentioned the avocado by its English spelling in 1696.

Health benefits of Avocado

Avocados contain nearly 20 vitamins and minerals including potassium, vitamin E, vitamin C, B vitamins, and folic acid. They are rich sources of heart-healthy monounsaturated fat and dietary fiber with roughly 50 calories per 1-ounce serving. The high fat content of avocados promotes satiety; helps regulate blood sugar, aids in hormone regulation, and in the absorption of essential fat-soluble vitamins.

In addition to monounsaturated fat, avocados also contain phytosterols, plant sterols that compete with cholesterol for absorption, thus helping reduce blood cholesterol levels. What’s more, research suggests that avocados may reduce markers of inflammation associated with heart disease.

Numerous studies show that it has powerful beneficial effects on health. Here are some of the health benefits of avocado that are supported by scientific research.

1. Help Prevent Cancer

There is limited proof that avocado may be beneficial in preventing cancer. One research showed that it may help reduce side effects of chemotherapy in human lymphocytes. Avocado extract has also been shown to prevent the growth of prostate cancer cells. However, keep in mind that these researches were done in isolated cells and don’t really prove anything about what happens in a living, breathing human.(1), (2)

2. Protects Your Eyesight

Not only does avocado help you with antioxidant absorption from other foods, but the fruit is also rich in antioxidants itself. Some of the antioxidants found in avocado are Lutein and Zeaxanthin, which are vital for eye health and eyesight. Some researches have come up with the results where these antioxidants are associated with the reduced risk of cataracts and macular degeneration, particularly common in the elderly. As a result, consuming sufficient amount of avocado will provide your body with benefits for your eyes over the long term.(3), (4), (5), (6)

3. Provides Dental Care

 Consumption of avocado will bring back the freshness in your breath. Many people struggle with bad breath due to indigestion or an upset stomach. Halitosis is the main cause of bad breath, but it can be removed by improving digestive health.

The antibacterial and antioxidant properties of flavonoids found in avocado help you get rid of bad breath because they have the ability to kill the bacteria in your mouth. Additionally, avocado has been related with preventing oral cancers.(7)

4. Contain More Potassium than Bananas

Potassium is a nutrient that most people aren’t getting enough of. This nutrient helps maintain electrical gradients in the body’s cells and serves various important functions. Avocados are actually very high in potassium… with a 100 gram (3.5 ounce) serving containing 14% of the RDA, compared to 10% in bananas, which are a typical high potassium food. Several studies show that having a high potassium intake is related to reduced blood pressure, a major risk factor for heart attacks, strokes and kidney failure.(8), (9), (10)

5. Beneficial for Pregnant Women

One research concluded that, avocado is a great choice for pregnant women because it contains a great amount of folic acid, which is significant for preventing birth defects such as spina bifida and neural tube. The B vitamin is essential and this is the reason why doctors recommend high amounts of avocado intake before and during pregnancy. Avocado contains around 45 mcg of folate per half-cup; more than any other fruit. Vitamin K is yet another valuable nutrient for pregnant women.

Luckily for moms-to-be, it is also found in high concentration in avocado. Deficiency in vitamin K causes bleeding, or VKDB, which is a condition where newborn babies cannot stop bleeding because their blood does not contain enough Vitamin K. Consuming vitamin K rich fruits during pregnancy help you pass more of it to your unborn child.(11)

6. Good for Constipation

Despite their creamy texture, avocados are actually a high fiber food, with 8 grams of both soluble and insoluble fiber per cup of the fresh fruit.

This fiber is beneficial for improving digestion, encouraging regular bowel movements and well known to help prevent constipation. In fact, avocados are often recommended as a mild laxative for people having trouble going to the toilet. If you’ve been having problems with elimination, whether constipation or diarrhea, then getting more fiber-rich foods like avocados can definitely help keep you regular.

7. Can Lower Cholesterol and Triglyceride Levels

Heart disease is the most common cause of death in the world. It is known that several blood markers are linked to an increased risk. This includes cholesterol, triglycerides, inflammatory markers, blood pressure and various others. The effect of avocado on some of these risk factors has been studied in 8 human controlled trials. These are studies where people are split into groups… one group is instructed to eat avocados, while the other is not. Then researchers see what happens to their blood markers over time.

Researches have shown that avocados can:

• Reduce total cholesterol levels significantly.
• Reduce blood triglycerides by up to 20%.
• Lower LDL cholesterol by up to 22%.
• Increase HDL (the “good”) cholesterol by up to 11%.

One of the studies showed that including avocado in a low-fat vegetarian diet led to improvements in the cholesterol profile. Unfortunately, all of the human studies were small (13-37 subjects) and short-term (1-4 weeks), but the results were impressive however.(12), (13), (14), (15), (16), (17), (18), (19), (20)

8. Protects Liver from Disease

Potassium is one of the minerals that help in maintaining a normal heart rate. Avocados are a good source of potassium and their inclusion in your diet provide other benefits too. It is important to make sure that potassium levels are not too high as that can also be dangerous for the heart. Potassium is a key aspect of maintaining fluid balance through chemical channels for cells and organs. This balance of fluid is also vital for the functioning of the kidney, which handles the movement of fluid and toxins through the body.(23)

10. Encourages Longevity

 Avocado is one of the fruits related with healthy aging and longevity because of its effective compounds that regenerate your body.

Research investigating avocado and its effects on osteoarthritis suggest that 300 mg of avocado or soy supplements appear to be beneficial for patients with hip or knee osteoarthritis. Additionally, the levels of essential minerals in avocados are substantial; they include phosphorus, copper, zinc, and trace amounts of selenium and calcium. Because of these compounds, the risk of osteoporosis is reduced and improvements in bone mineral density come as a natural consequence.(34), (35), (36) 

16. Causes Satiety and Weight Loss

There is a misconception about avocados when it comes to weight loss programs and diets.

On the contrary, eating and incorporating avocados into your diet is not going to prevent you from losing weight. In fact, including avocados to your meals will help you feel more satiated, which will eventually reduce your desire to eat more and eat more often. It’s been proven that similar meals without avocados do not cause as much satiety. It is clear that avocados may be an excellent supplement to an effective weight loss diet. Plus, what makes avocado a weight-loss friendly food is the fact it is high in fiber, low in carbs, and does not raise blood sugar levels.(37), (38), (39), (40) 

17. Protect the Eyes

Not only avocados increase antioxidant absorption from other foods, they are also high in antioxidants themselves.

Thus, eating avocados should have benefits for eye health over the long term.(41), (42), (43), (44) 

18. Loaded With Fiber

Fiber is another nutrient found in relatively large amounts in avocado. Fiber is indigestible plant matter that can contribute to weight loss, reduce blood sugar spikes and is strongly linked to a lower risk of many diseases. A difference is often made between soluble and insoluble fiber. Soluble fiber is known to be able to feed the friendly gut bacteria in the intestine, which are very important for the optimal function of our bodies. A 100 gram (3.5 ounce) serving of avocado contains 7 grams of fiber, which is 27% of the recommended daily amount. About 25% of the fiber in avocado is soluble, while 75% is insoluble.(45), (46), (47), (48), (49)

19. Wound-Healing Activities

Being an excellent source of enrichment for dry, chapped, or damaged skin, avocado can also heal wounds all over your body. According to a study, avocado has been recommended to heal wounds in rats. Namely, the rats were divided into four groups of five and received either topical or oral treatment. As a result, complete healing was observed in the rats who received either treatment type.(50)

20. Great for Your Skin

 Avocados are high in fat, but these are the “good” polyunsaturated and monounsaturated fats that are healthy for your system, not the saturated fats that block your arteries and are bad for your circulation. The “good” fats in avocados can actually protect your skin. Polyunsaturated fats keep your skin protected from sun damage and inflammation.

Monounsaturated fats keep the top layer of skin moisturized so that it’s healthy and guarded from premature wrinkles. The Vitamin C and E in avocados also protect your skin cells by keeping your skin hydrated. Many people use mashed, raw avocado as a face mask since it contains so many good fats and oils for the skin. Ingesting these oils and vitamins by adding avocados to sandwiches and salads can also protect your skin and keep it looking radiant!

21. Improves Your Mood

 Avocados are high in folate, which falls into the family of B vitamins. You may have heard that pregnant women should get enough folate in their diet, but this substance is good for everyone when it comes to regulating mood. Homocysteine naturally forms in the body, but too much of this substance will block the production of serotonin and dopamine; these chemicals regulate mood, as well as encouraging restful sleep at night.

Folate in avocados helps to prevent excessive amounts of homocysteine from forming in your body so that it can produce serotonin and dopamine. In turn, you’re at less risk from depression. Being able to sleep soundly and regularly can also mean a healthier, happier mood, as you’re less fatigued and will have more energy after a good night’s sleep. By eating more avocados, you may see that you sleep more soundly and feel more rested and energetic throughout the day, and have a better mood as well.

22. Lower risk of depression

Foods containing high levels of folate may help to decrease the risk of depression as folate helps to prevent the build-up of homocysteine, a substance that can impair circulation and delivery of nutrients to the brain. Excess homocysteine can also interfere with the production of the serotonin, dopamine, and norepinephrine, which regulate mood, sleep and appetite.

The Medicinal Uses of Avocado

The seeds, shoots, root bark and leaves of avocado are used for medicinal uses. The fruit extracts is used for skin care and cosmetic products to soften the dry skin.

The Leaves of Avocado

The avocado leaves have antibiotic properties which helps to treat vermifuge, antihelminthics and dysentery. The pyorrhea can be treated if chewed. The wounds can be cured if leaves poultices are applied. The avocado leaves if decoction helps to cure sore throat, manage menstruation, stomachis, diarrhea and hemorrhage.

The Seeds of Avocado

The avocado seeds have fungicidal, insecticidal and anti-microbial properties. The extracts of avocado seeds are used as ink and have colorant qualities. It also cures tooth ache and oral bacterial illnesses. Dandruff can be blocked by the use of powder seed. Skin outbreaks can be treated with the avocado oil extracts.

How to Buy Avocado

The first thing you need to know when buying avocado is its origin. If you are going to use an avocado for an immediate purpose, select a ripe, ready-to-eat avocado. However, if you are going to buy avocado in advance, it would be better if you buy the firm types and then have them ripen and ready-to-eat at home.

You should avoid buying avocados that are overly soft and mushy. This means that the fruit is too ripe. Dark blemishes, bruises, dents, and brown spots should also be avoided when selecting an avocado.

Be mindful about the attributes of the avocados that you are going to buy

Ripeness: One of the most important things when buying an avocado is its ripeness. You may check it by holding the avocado in your hand and gently squeezing it. However, you should be careful not to press the avocado with your fingertips too much as it can cause bruising. If you are holding a ripe avocado, it will not be overly squishy. If it a bit hard, then it is probably under ripe and needs a few days to ripen. Nonetheless, you can still buy an under ripe avocado and ripen it at home.

Look: Another attribute to check for is the look of an avocado. Opt for an avocado with unblemished skin. Avocados that are too shiny are still under ripe. But, once again, you may choose to buy these and ripen them at home.

Color: Color is also an important attribute and can vary depending on the variety. California Hass avocados are distinctive for their color, which usually turns dark green or purplish-black as they ripen. On the other hand, Florida avocados have lighter-green skin combined with yellowish tone even when they are already ripe.

How to Store Avocado

If you have a fresh avocado, you can store it in its cut and uncut form. Time will vary when it comes to how long you can store fresh fruit. Be it cut or uncut, ripe or unripe, all of these factors will play a role in how long the fruit can be stored. Cut avocados are naturally susceptible to oxidizing if left unprotected, thus turning brown.

When you cut an avocado, its cellular walls get broken which causes oxidation to occur.

However, this process of oxidation can be prevented. All you have to do is add an acidic agent to an avocado and limit the surface area that is exposed to the air.

Here are some of the best suggested acidic agents:

• Orange juice
• Lime juice
• Lemon juice
• Onion
• Tomatoes
