The Amazing Health Benefits Avocados


Avocados are pear shaped fruits of Central American origin. Unlike most other fruits, they feature high fat content and have more calories. Nonetheless, they are among the popular fruits having a good nutritional profile and health benefiting properties.

Botanically, the fruit belongs to the family of Lauraceae, the family that also includes some unusual members like bay laurel, cinnamon, etc. Scientific name is Persea Americana.

The avocado is a rather unique type of fruit. Most fruit consists primarily of carbohydrate, while avocado is high in healthy fats. Because of its high nutrient value this fruit is added to all sorts of dishes due to its good flavor and rich texture.

There are many kinds of avocados, and the shape (from the pear shaped to round) and color (from green to black) can vary between them. They can also weigh anywhere from 8 ounces (220 grams) to 3 pounds (1.4 kg).

Here are some of the most abundant nutrients, in a single 3.5 ounce (100 gram) serving:
Vitamin K: 26% of the RDA.

Folate: 20% of the RDA.
Vitamin C: 17% of the RDA.
Potassium: 14% of the RDA.
Vitamin B5: 14% of the RDA.
Vitamin B6: 13% of the RDA.
Vitamin E: 10% of the RDA.

Then it contains small amounts of Magnesium, Manganese, Copper, Iron, Zinc, Phosphorous, Vitamin A, B1 (Thiamine), B2 (Riboflavin) and B3 (Niacin).

They 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 contains 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 linked to reduced blood pressure, a major risk factor for heart attacks, strokes and kidney failure.

Avocados Are 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 distinction 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 an avocado are soluble, while 75% is insoluble.

Eating Avocados 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 effects of avocado on some of these risk factors have 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.

These studies 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%.

Avocados Are Loaded With Powerful Antioxidants That Can Protect the Eyes
Not only do avocados increase antioxidant absorption from other foods, they are also high in antioxidants themselves. This includes nutrients called Lutein and Zeaxanthin, which are incredibly important for eye health. Studies show that these nutrients are linked to a drastically reduced risk of cataracts and macular degeneration, which are common in the elderly. Therefore, eating avocados should have benefits for eye health over the long term.

Avocado Helps in Preventing Cancer
Avocados have been shown to offer significant protection against breast cancer because it contains a concentrated amount of carotenoids. It also helps the body absorb carotenoids from carotenoid-rich vegetables due to its fat content.

In a laboratory study published in the Journal of Nutritional Biochemistry, an extract of avocado containing these carotenoids and tocopherols inhibited the growth of both androgen-dependent and androgen-independent prostate cancer cells.

A study published in the Journal of Nutrition stated that consuming carotenoid-rich foods along with monounsaturated fat-rich avocados can enhance the bioavailability of these nutrients. Not only did adding avocado to a salad or to salsa greatly increase study participants’ absorption of carotenoids from these foods, but the improvement in carotenoid availability occurred even when a very small amount was used – as little as 2 ounces per serving.

Regulating blood sugar
According to Reader’s Digest, avocados’ high levels of monounsaturated fats can help stop insulin resistance, which helps to regulate blood sugar levels. Furthermore, the soluble fiber in avocados can help keep blood sugar levels steady. In comparison to other fruits, the low carb and sugar levels in avocados also help maintain blood sugar.

Immune system
Glutathione is a powerful antioxidant associated with immune system health. A 2000 report in the journal Proceedings of the Nutrition Society stated, “The immune system works best if the lymphoid cells have a delicately balanced intermediate level of glutathione.” Avocados are a good source of this substance, according to the American National University.

Pregnancy and preventing birth defects
According to the California Avocado Commission, avocados are a great choice for moms-to-be. Avocados contain a significant amount of folic acid, which is essential to preventing birth defects like spina bifida and neural tube defects.

Skin Care
The avocado oil is added in many cosmetics because of its ability to nourish the skin and make your skin glow. It also aids in treating psoriasis, a skin disease that causes skin redness and irritation.

Anti-aging properties
Being rich in antioxidants, avocado is beneficial in preventing aging symptoms. The glutathione in avocado may boost immune systems, slows the aging process, and encourages a healthy nervous system.

Cure bad breath
Avocados are one of the best natural mouth wash and bad breath remedies. It is cleanses intestine, which is the real cause of coated tongue and bad breath.

Nick and peel method
The method you use to peel an avocado can make a difference to your health. Research has shown that the greatest concentration of carotenoids in avocado occurs in the dark green flesh that lies just beneath the skin. You don't want to slice into that dark green portion any more than necessary when you are peeling an avocado. For this reason, the best method is what the California Avocado Commission has called the "nick and peel" method. In this method, you actually end up peeling the avocado with your hands in the same way that you would peel a banana. 

The first step in the nick-and-peel method is to cut into the avocado lengthwise, producing two long avocado halves that are still connected in the middle by the seed. Next, you take hold of both halves and twist them in opposite directions until they naturally separate. At this point, remove the seed and cut each of the halves lengthwise to produce long quartered sections of the avocado. You can use your thumb and index finger to grip the edge of the skin on each quarter and peel it off, just as you would do with a banana skin. The final result is a peeled avocado that contains most of that dark green outermost flesh so rich in carotenoid antioxidants!

Avocado despite its dark green skin and largely greenish inner pulp is now known to contain a spectacular array of carotenoids. Researchers believe that avocado's amazing carotenoid diversity is a key factor in the anti-inflammatory properties of this vegetable. The list of carotenoids found in avocado includes well-known carotenoids like beta-carotene, alpha-carotene and lutein, but also many lesser known carotenoids including neochrome, neoxanthin, chrysanthemaxanthin, beta-Cryptoxanthin, zeaxanthin, and violaxanthin.

How Much Avocado Can a Diabetic Eat?
If you have diabetes, you know that food plays a big role in controlling your blood sugar levels. Carbohydrate--containing foods, which include sugar, sweets, sugary drinks, grains, starchy vegetables, fruits and some dairy, are converted to sugar during the digestion process and therefore contribute to raising your blood sugar levels after eating. A high--carb intake will result in high blood sugar levels.

Nutrition Facts
The nutrition facts for avocado depend on its size. For example, a whole California avocado provides about 227 calories, 11.8 grams of carbohydrates and 9.2 grams of fiber, while a Florida avocado is larger and contains 365 calories, 23.8 grams of carbohydrates and 17.0 grams of fiber. With diabetes, carbohydrates elevate your blood sugar levels, but only the starch and sugar part of the total carbohydrates, not the fiber.

Available Carbohydrate and Diabetes
To better estimate the effect of avocado on your blood sugar levels, you can calculate their available carbohydrate content by subtracting fiber from the total carbs. In the case of a California avocado, you get 2.6 grams of available carbohydrates, while a Florida avocado contains 6.8 grams of available carbohydrates because of its larger size. Usually, diabetics are recommended to limit their carb intake to 45 grams to 60 grams per meal. The avocado contains very small amounts of available carbohydrates and are not problematic for diabetes control, even if you eat a whole, large avocado.

Adding Avocados to Your Diet
Avocados are an extremely versatile fruit! Whether eaten alone, added to meals or included as an ingredient in a variety of recipes, avocados are a great way to add flavor, productivity and nutrients to your plate. Try avocados in the following ways:

  • Add a serving to a salad, soup or sandwich
  • Serve guacamole as a dip for whole grain chips, crackers or vegetables
  • Include avocados with breakfast by adding to an omelet, blending into a smoothie or spreading on.
  • Whole grain toast
  • Avocados can be used as a fat replacement when baking

This fruits are much helpful in regular diet and we need to preserve them in a cool place.
