Benefits of Avocado
.
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 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.
.
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 .
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.
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 avocado is soluble, while 75% is insoluble .
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.
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 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.
Therefore I don't think this particular study carries much weight.
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.
