Miraculous Misconceptions: Common Myths about Olive Oil

This week alone I received questions from three people about olive oil.  The questions were so interesting that I decided to turn them into a quick blog.  Most of you have probably heard that Olive Oil contains a combination of polyunsaturated and monounsaturated fats.  To keep it simple we’ll call these the ‘good fats.’  ‘Bad fats’ are saturated, hydrogenated, or Trans fats such as shortening, butter, margarine, palm oils, and coconut oils.

Unsaturated fats, or your poly and mono unsaturated fats have proved to decrease blood cholesterol and reduce risk of heart disease and as this research continues to be published, a lot of the general public has moved to olive oil for their cooking source, spritzer, or salad dressing.

As the use of olive oil multiplies, rumbles have spread like wildfire that olive oil is bad to cook with because it can turn to a saturated fat or that olive oil loses its nutrient composition at high heat.  When researching these claims I went to the International Olive Oil Council and publications by Dr. Kiritsakis, a world renowned oil chemist, and this is what I found.

Basically, all food can lose some nutrients during the heating process, but the breaking point for this with oils is the smoke point.  The smoke point varies by the type of oil and is basically the temperature at which oil burns.  Extra Virgin Olive Oil has the highest smoke point at 365-400 degrees Fahrenheit.  With this high smoke point it is thought that during normal cooking processes nutrients will not be lost, only the flavor.

As for olive oil turning into a saturated fat with high heat Dr. Kiritsakis believes hydrogenation occurs least in olive oil and that no home cook will ever experience enough hydrogenation when cooking to create a saturated fat.  The International Olive Oil Council echoes this by labeling Olive oil as the most stable fat when heated.

So, what oil should you use with cooking?  I say, stick with the olive oil.  The health benefits outweigh any myths out there.  Cooking some stir fry’s in high heat? Use the ‘extra virgin’ olive oil as it has the highest smoke point.  Frying with olive oil- ay yi yi, doesn’t that negate the whole purpose?

What oils do you use to cook with?  Do you have a favorite? I just discovered the neatest store Lebherz Oil and Vinegar Emporium in Frederick, MD and cannot believe the selection. If you live in the Frederick area, check it out.  Be well.

Make it Happen

Parents, I see you. I see you putting everyone else's needs in front of yours. I see your dark circles under your eyes, your gray hair, that your wasting away, or that you've collectively gained weight over the years. It's time to put yourselves first because if you don't take care of yourself you won't be around to keep taking care of everyone else. So often friends, acquaintances, or clients say to me, "I don't know how you find the time to exercise." "How can you take the time away from everything else and get away to exercise?" "I wish I could actually focus on myself and exercise." Exercise to me is self care. It produces endorphins faster than any other activity I engage in. It  reduces my stress, keeps me healthy, increases flexibility, and gives me more energy to be on point with my busy kids and my demanding job. My exercise isn't extravagant and it doesn't take too much time. Here's my secret. I always

Why this Dietitian Cares more about your PREbiotics than your PRObiotic Pill

Clients ask me all the time what I think of their brand of probiotic or which one they should start taking.  Studies have shown that probiotic supplements definitely have their place in certain circumstances (that’s a whole other blog for another time), but my bigger concern is... what are you feeding the ones you have already? “Probiotics” is just a fancy word for helpful bacteria.  Even if you don’t take a pill, you have these little guys in your digestive track.  The problem right now is that current probiotic supplements can only include the bacteria that scientists have been able to 1) identify and 2) put in a pill without them dying right away.   However, we (probiotic and non-probiotic users alike) have so many different strains of bacteria (somewhere in the neighborhood of billions) who do so much good for us such as make vitamins and help battle bad bacteria.  BUT - just like us - they need to eat!  A recent study showed that a diet high in protein is not in their

To The Bones- A review from a dietitian

Friday July 14th, Netflix premiered the movie To The Bone.  Prior to the premier many had opinions of the movie. Some were fearful that it would glorify an Eating Disorder, some felt the movie would put too much focus on extremely thin patients with Eating Disorders neglecting those that are within normal weight but still extremely sick, and many had a lot of opinions about the lead actress who lost a significant amount of weight for the role disclosing she is in recovery for an Eating Disorder. My colleagues and I discussed the pretense of the movie, I communicated to families that the movie was coming out in case their daughters and sons watched the movie, and Friday I went home from work and viewed the movie. Although Hollywood has a way of sensationalizing everything there was a lot that the movie got right. The opening scene where Ellen counts the calories as soon as she sees the food is a good depiction of how someone with an Eating Disorder thinks. Food is not sensual it i
