The avocado
is a rather unique type of fruit. Most fruit consists primarily of
carbohydrate, while avocado is high in healthy fats. Numerous studies show that it has powerful
beneficial effects on health.
Here are 12
health benefits of avocado that are supported by scientific research.
1. Avocado is Incredibly Nutritious.
What we
refer to as “avocado” is the fruit of the avocado tree, called Persea
Americana.This fruit is prized for its high nutrient value and is added to all sorts of dishes due to its good flavor and rich texture. It is the main ingredient in guacamole.
These days, the avocado has become an incredibly popular food among health conscious individuals. It is often referred to as a superfood… which is not surprising given its health properties.
There are many kinds of avocados and the shape (from 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). The most popular type is called Hass avocado.
This is what a typical avocado looks like:
It is often
called “alligator pear,” which is very descriptive because it tends to be
shaped like a pear and have green, bumpy skin… like an alligator. The
yellow-green flesh inside the fruit is eaten, but the skin and seed are
discarded. Avocados are very nutritious and contain a wide variety of
nutrients, including 20 different vitamins and minerals.
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).
This is
coming with 160 calories, 2 grams of protein and 15 grams of healthy fats.
Although it contains 9 grams of carbs, 7 of those are fiber so there are only 2
“net” carbs, making this a low-carb friendly plant food. Avocados do not
contain any cholesterol or sodium, and are low in saturated fat. I personally
don’t think that matters, but this is one of the reasons they are favored by
many “old school” experts who still believe these things are inherently
harmful.
2. 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 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 linked to reduced blood
pressure, a major risk factor for heart attacks, strokes and kidney failure.
3. Avocado is loaded with
Heart-Healthy Monounsaturated Fatty Acids.
Again,
avocado is a high fat food. In fact, 77% of the calories in it are from fat,
making it one of the fattiest plant foods in existence. But they don’t just
contain any fat… the majority of the fat in avocado is oleic acid. This is a
monounsaturated fatty acid that is also the major component in olive oil and
believed to be responsible for some of its beneficial effects.
Oleic acid
has been linked to reduced inflammation and been shown to have beneficial
effects on genes linked to cancer. The fats in avocado are also pretty resistant
to heat-induced oxidation, making avocado oil a healthy and safe choice for
cooking.
4. 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.
5. 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 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.
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%.
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 nonetheless. Bottom Line: Numerous
studies have shown that eating avocado can improve heart disease risk factors
like Total, LDL and HDL cholesterol, as well as blood triglycerides.
6. People Who Eat Avocados Tend to be
Healthier
One study
looked at the dietary habits and health of people who eat avocados. They
analyzed data from 17,567 participants in the NHANES survey in the U.S.
Avocado
consumers were found to be much healthier than people who didn’t eat avocados.
They had a
much higher nutrient intake and were half as likely to have metabolic syndrome,
a cluster of symptoms that are a major risk factor for heart disease and
diabetes.
People who
ate avocados regularly also weighed less, had a lower BMI (Body Mass Index) and
significantly less belly fat. They also had more HDL (the “good”) cholesterol. However…
correlation does not imply causation and there is no guarantee that the
avocados caused these people to be in better health.
7. The Fat in Them Can Help You
Absorb Nutrients from Plant Foods.
When it
comes to nutrients, the total amount of them is not the only thing that
matters. We also need
to be able to absorb them… move them from the digestive tract and into the
body, where they can be used. Some nutrients are “fat soluble,” meaning that
they need to be combined with fat in order to be utilized.
This
includes vitamins A, D, E and K… along with antioxidants like carotenoids. One
study showed that adding avocado or avocado oil to either salad or salsa can
increase antioxidant absorption by 2.6 to 15-fold. So… not only is avocado
highly nutritious, it can dramatically increase the nutrient value of other
plant foods that you are eating. This is an excellent reason to always include
a healthy fat source when you eat veggies. Without it, a lot of the beneficial
plant nutrients will go to waste.
8. 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.
9. Avocado May Help Prevent Cancer
There is
limited evidence that avocado may be beneficial in preventing cancer. One study
showed that it may help reduce side effects of chemotherapy in human lymphocytes.
Avocado extract has also been shown to inhibit the growth of prostate cancer
cells.
However,
keep in mind that these studies were done in isolated cells and don’t really
prove anything about what happens in a living, breathing human.
10. Avocado Extract May Help Relieve
Symptoms of Arthritis
Arthritis is
a common problem in Western countries. There are many types of arthritis, and
these are often chronic problems that people have for the rest of their lives.
Multiple
studies have shown that extracts from avocado and soybean oil, called Avocado
and Soybean unsaponifiables, can reduce symptoms of arthritis of the bones,
called osteoarthritis. Whether
avocados themselves can have this effect, and not just the extract, remains to
be seen.
11. Eating Avocado May Help You Lose
Weight
There is
some evidence that avocados are a weight loss friendly food. In one study,
people were split into groups. One group was instructed to eat a meal that
contained avocado, the other a similar meal without avocado. Then they were
asked a series of questions related to hunger and satiety.
The people
eating the avocado felt 23% more satisfied and had a 28% lower desire to eat
over the next 5 hours. If this holds true in the long-term, then including
avocados in your diet could help you naturally eat fewer calories and have an
easier time sticking to a healthy diet.
Avocados are
also high in fiber, and very low in carbs, two attributes that should also help
promote weight loss, at least in the context of a healthy, real food based
diet.
12. Avocado is Delicious and Easy to
Incorporate in The Diet.
Not only are
avocados healthy, they’re also incredibly delicious and go with all sorts of
foods. You can add them to salads and various sorts of recipes, or you can
simply scoop them out with a spoon and eat them plain. They have a creamy,
rich, fatty texture and blend well with various other ingredients.A notable mention is guacamole, which is arguably the most famous use of avocados. It includes avocado along with ingredients like salt, garlic, lime and a few others depending on the recipe.
