Is Olive Oil Good for You?
Growing up, in my experience, the message was clear – fats make you fat.
Whether eating a pile of French fries or slapping another blob of peanut butter on my PB&J, I was preconditioned to assume that fats are the enemy and that I should avoid them at all costs. (It didn’t work out for me most of my life, lol.)
Yet, this is not the case.
Nowadays, at one point or another, I’m sure someone has come along to convince you that olive oil is healthy. But why? I mean, what alternatives could you be using that are so bad?
Olive oil has tons of benefits, but chances are you don’t know what they are.
I didn’t know the benefits until I started this company, threw myself (well, not literally) into the olive oil sphere, and learned everything I could.
So then, why is olive oil good for you?
Well, if somebody asks you why you choose olive oil over butter, I aim for you to give them a concrete answer.
Read below to learn 10 functional benefits of olive oil.
1. Olive Oil Contributes to a Balanced Diet
Again, fats are not the enemy (but some clarification on this briefly).
Fats are an essential part of our diets. Without a healthy source of fat, our bodies wouldn’t be able to break down essential nutrients.
Certain vitamins, like vitamins A, D, and E, are fat-soluble. However, our bodies do not produce their own fatty acids. This means we could not absorb them without help from fats like olive oil.
Olive oil provides energy for our bodies and assists in cell development. As a healthy fat, it can also promote nutrient absorption and help our bodies perform daily functions.
Without healthy fat sources like olive oil, our bodies would not function to their fullest potential.
2. It Does Not Contain Trans Fats or Saturated Fats
You’ve most likely heard of several types of fats, even if you may not know what they mean. Olive oil, a monounsaturated fat, is only one of them.
But not all fats are created equal.
Saturated Fats
Saturated fats are usually found in your generally “unhealthy” food options. These can be manufactured or naturally occurring. They’re dubbed “saturated” fats because their molecular chain is saturated with hydrogen.
Examples of prime sources of saturated fats include:
Whipped Cream
Processed Meats
Whole Milk
Lard
Trans Fats
Trans fats are a type of saturated fat. Chemically speaking, trans fats differ from other fats because they are produced through partial hydrogenation.
This process turns liquid fats into solid fats at room temperature. This is usually done by adding hydrogen to liquid vegetable oil.
Trans fats came into the general conscience in 2006, when the FDA required nutrition labels to list them.
Food manufacturers scrambled to change ingredients because foods high in trans fat were seen as unmarketable under the new regulations (hey, that’s a good thing the government has done for us!).
Negative Effects
Consuming either of these fats could lower your high-density lipoprotein levels (HDL or good cholesterol) and raise your low-density lipoprotein levels (LDL or bad cholesterol).
Meanwhile, plaque can build up in your arteries, and eventually, you reduce your cardiovascular function, causing heart disease and even strokes.
A diet low in saturated fats is the way to go, so olive oil is a great alternative.
3. It’s a Monounsaturated Fat
Monounsaturated fats stand out in the fat family because of their health benefits.
Monounsaturated fats contain double bonds in their chemical structure. Saturated fats do not, which is why they’re filled with hydrogen and don’t break down as well.
“Mono” meaning “one, implies that monounsaturated fats have a single double bond. This is good because the molecule isn’t saturated with hydrogen.
The double bonds allow their molecules to bend, creating more loosely packed molecules. These molecules allow olive oil to remain a liquid at room temperature.
Monounsaturated fats are found in a variety of naturally occurring foods. Nuts and seeds, salmon, avocados, and, you guessed it, olives are all excellent sources of this healthy fat.
High in monounsaturated fat, olive oil can raise your HDL cholesterol and lower your LDL cholesterol.
It works in favor of your body, which needs it to survive and function.
4. It Contains Antioxidants
What are the olive oil nutrition facts?
Spoiler alert: FULL of antioxidants.
Olive oil contains nutrients and antioxidants essential for our body’s functions. It contains Vitamins K, E, and oleic acid.
An imbalance of antioxidants can cause a myriad of diseases. Olive oil contains high levels of these nutrients.
Vitamin K is known for helping your blood clot in cases of injury. It’s also known for regulating blood calcium levels and promoting bone metabolism.
Low vitamin K levels have even been linked to decreased calcium absorption, which can eventually cause lower bone density and osteoporosis.
Vitamin E helps promote healthy skin, your immune system, and regular cell function. It can act as an anti-inflammatory and reduce the effects of harmful UV rays.
Oleic acid is a naturally occurring fatty acid. It has been studied for its benefits in reducing cancer-causing cells and the chances of getting Alzheimer’s disease.
5. It’s Heart Healthy
With all the benefits of monounsaturated fats and antioxidants, olive oil can be heart-healthy!
Like all fats, moderation is always recommended. However, olive oil’s nutrients defend it against deadly diseases like cardiovascular disease.
Many factors, including lack of exercise, a poor diet, and smoking, cause cardiovascular and heart diseases. Your diet is an essential aspect of this because your food contains fats that can help prevent or speed up the progression of these diseases. Consuming foods high in saturated fats can cause plaque buildup.
Plaque buildup lowers blood flow to your body and can cause significant problems. Healthy fats like olive oil are suitable for your body and allow proper nutrient absorption. Olive oil doesn’t build up in your arteries the same way unhealthy saturated fats usually do.
Converting to olive oil gives your body the healthy fats to function. You’re also lowering your chances of getting heart and cardiovascular diseases.
6. You Could Reduce Your Chances of Experiencing a Stroke
Several different factors, including improper cardiovascular function, cause strokes.
One of these causes can be a lack of blood flow to the brain. Sometimes fatty deposits in the arteries can become dislodged and find their way into your brain. These deposits can block blood vessels, causing a stroke.
Strokes can also be caused by reduced blood flow in our blood vessels. This can happen when blood cannot reach a blood vessel and clots. Like fatty deposits, this clot can also block brain vessels.
Monounsaturated fats assist in maintaining proper cardiovascular health. By providing our bodies with healthy fats like olive oil, we increase our chances of preventing a stroke.
7. It’s Anti-Inflammatory
Olive oil contains nutrients that can reduce inflammation in your body, specifically, a nutrient known as oleocanthal.
Oleocanthal is a phenylethanoid, a naturally occurring compound with health-promoting properties. It has even been shown to have a similar effect to a small dose of ibuprofen.
Prostaglandins are key in producing the redness and swelling that develop with inflammation. Oleocanthal staves off inflammation by reducing the concentration of prostaglandins at an inflammation site.
Olive oil’s anti-inflammatory properties vary depending on its purity and type, but it is the only cooking oil that contains the phenylethanoid oleocanthal.
8. Your Body Can Absorb It
The great thing about naturally occurring fats like olive oil is that your body can absorb them.
Remember those double and single molecular bonds we mentioned earlier? The double bonds in monounsaturated fats like olive oil make it easier for your body to break down and digest.
This also makes them a good source of energy. Healthy fats throughout the day can regulate your energy levels.
9. It Burns at a Higher Temperature Than Most Fats
You might think, “Because it burns at a higher temperature than most fats,” you’re running out of ways to get to 10, Chris.
Hear me out; there’s a good reason this is on the list.
We’re all guilty of burning our food at one point or another. However, the effects of burning food can be more dangerous than we realize.
Burning food creates a cancer-causing agent called acrylamide.
Acrylamide is produced when starchy foods are cooked at high temperatures. A chemical reaction occurs between sugars and amino acids in the food, causing the pungent smell and black color when burned.
This harmful compound is produced and often consumed, regardless of its negative health consequences.
However, when cooking with olive oil, the chances of producing acrylamide are much lower. With a relatively high burning temperature, burning food while cooking with it is more difficult! At over 400 degrees, the smoking point of olive oil is pretty high.
Burning anything can cause us to ingest harmful chemicals, but you don’t have to worry about this as much with olive oil.
By using olive oil when you cook, you’re significantly reducing your chance of consuming cancerous chemicals.
10. It Can Combat Cognitive Decline
Olive oil and all its nutrients can also help slow brain degeneration.
Preliminary research has shown olive oil to reduce one’s chances of developing Alzheimer’s disease and other neurodegenerative diseases.
As someone who has lost a close family member to Alzheimer’s, this one hits home the most.
The chemical properties have been studied to help block and remove plaque in the brain that causes Alzheimer’s.
You potentially reduce your risk of developing a neurodegenerative disease by consuming olive oil.
Conclusion: Why Is Olive Oil Good for You?
TL;DR – Olive oil is a healthy, primarily monounsaturated fat.
Our bodies easily absorb this fat and can promote healthier lifestyles.
It’s great for cooking and even better tasting.
Antioxidant-filled, this healthy fat should be in everyone’s kitchen.
Whether you choose plain extra virgin olive oil or flavored olive oils, deciding about vegetable oil vs. olive oil is a no-brainer.
So next time someone asks you, “Why is olive oil good for you?”, tell them it’s part of a balanced diet!
You’ll be doing yourself (and your heart) a favor by choosing olive oil.
