Myth Busters: Are Different Cooking Oils Actually Better for You?

EducatorsParents

Kristen Ziesmer headshot.There are so many different cooking oils on the market, and it can be difficult to know which oil is the healthiest to use when cooking or baking for your young athletes. A high-quality oil can provide vital nutrition, and here, TrueSport Expert Kristen Ziesmer, a registered dietitian and board-certified specialist in sports dietetics, is breaking down what you need to know about oil selection and how to pick the right type for any meal.

 

Don’t be afraid of oil

For many of us who had our formative years in the 80s and 90s, ‘fat’ was a bad word. Salad dressings that were fat-free were the healthy option and adding oil to a dish rather than coating a pan with non-stick spray was heresy for the health-minded. But we’ve since learned that certain fats aren’t just flavor-enhancing, they’re also essential to our overall health.

So, before we discuss which oils to use, Ziesmer urges parents to get rid of any misconceptions about oil being a bad thing. Especially for young athletes who are training hard, the extra calories from oil in addition to the essential nutrients it provides can be game-changing.

 

All oil isn’t created equal

A variety of different cooking oils in glass.While the caloric content of any oil is going to be very nearly even—about 120 calories and 14 grams of fat per tablespoon—they aren’t all the exact same nutritionally. While all oil is composed entirely of fat, the type of fat in each will differ. It may seem confusing, but there are different types of fats: saturated fats, trans fats, monounsaturated fats, and polyunsaturated fats. Ideally, a healthy diet eliminates trans fats entirely, since trans fats have no positive benefits and can raise bad cholesterol while lowering good cholesterol. Saturated fats should generally be eaten in moderation, while mono and poly-unsaturated fats are important for a healthy diet. Different oils will have different fat profiles: For instance, while olive oil only has two grams of saturated fat in that tablespoon, coconut oil will have 13 grams of saturated fat in the same serving.

 

Keep it simple, opt for olive oil

To simplify things immensely, a high-quality extra virgin olive oil is your best bet when it comes to oil consumption, says Ziesmer. Olive oil is made up of primarily mono and poly-unsaturated fats, including omega-3 and omega-6 fatty acids, which are critical for brain health. “It’s also rich in antioxidants and polyphenols, especially when you’re using extra-virgin olive oil rather than regular or virgin olive oil,” she adds.

 

Quality matters

Hands holding a green olive oil bottle in a grocery store aisle.If your olive oil comes in a clear plastic jug, that’s typically a sign that it’s not the best quality, says Ziesmer. Look for dark green glass bottles—and store them in a cool, dark place instead of sitting right on the stove where it gets hot. “Avoid leaving it out in the sun, since that light can break down the antioxidants,” she adds. Sometimes, companies mix other oils in with their olive oil to cut costs.

Ziesmer recommends choosing brands that have been third-party tested for purity—look for the North American Olive Oil Seal when purchasing your olive oil. Can’t pull that list up at the store? Ziesmer’s quick tip is that high quality olive oil will cost more than $10 per liter. If it’s cheaper than that, you’re likely buying a blend.

 

Pay attention to smoke point

You may have heard that olive oil has a low smoke point compared to other oils, and that’s true, relatively speaking. But the smoke point is still 410 degrees F for a quality extra-virgin olive oil, which means it can stand up to most cooking and baking applications. Just avoid cooking on extremely high heat or baking with it when a recipe calls for high heat in the oven. Once an oil is taken beyond its smoke point, Ziesmer says, it changes structurally, and goes from being a healthy oil to one that’s not so healthy. (Note: Virgin olive oil’s smoke point is considerably lower, so if you’re prone to turning up the heat, definitely make sure you’re using a higher quality extra-virgin oil!)

 

Experiment with other oils

Walnuts next to walnut oil in glass.If you enjoy the taste of coconut oil, it’s a great option when roasting vegetables. But because it’s primarily made up of saturated fat, Ziesmer warns that it shouldn’t be used exclusively. There are plenty of other tasty oils available now that add flavor and healthy fats, though typically, they’re not suited for more casual cooking purposes. Sesame and walnut oils can be great additions for a salad or when lightly sautéing vegetables, but have distinct flavors. Avocado oil is another option with a mild flavor, but it has a very low smoke point and shouldn’t be used for anything other than a very light sauté. Feel free to experiment with some of these other oils, since they all have slightly different fat profiles and contain different antioxidants.

 

Steer clear of these oils

With the exception of coconut oil, Ziesmer suggests avoiding oils that are in solid form at room temperature, since they’re high in saturated fat. This includes shortening and lard, as well as palm oil (which she notes also has environmental problems). “These oils raise inflammation in the body, so not only are they not great from a health standpoint, they also aren’t helping an athlete recover,” she adds. Skip deep-fried foods as well. In addition to being heavily processed, high in calories, and low in nutrient density, they’re also typically packed with trans fats—especially when something is fried in re-used oil. As oil is re-heated, the chemical structure changes and the trans-fats in it actually increase.

 

Avoid spray cans—Make your own!

Not only are sprays packed with extra chemicals and preservatives (even the sprays labeled ‘olive oil’ contain ingredients like soy lecithin and dimethyl silicone), they’re also pricey. And while they may be convenient, they don’t provide the good quality fats and the extra calories that your athlete needs. However, sometimes, you do want to keep the oil light. If you’re just hoping to coat a pan to cook up some scrambled eggs, grease a waffle maker, or quickly spritz a salad, Ziesmer suggests getting a small glass spray bottle (available in any kitchen store) and decanting olive oil into that. You’ll not only save money by not needing to buy new spray cans every time you run out, but you’ll also be using a small amount of healthy olive oil instead.

 

Add fat in the form of whole foods

Avocados sliced on a table.While adding fat in the form of oil is great, remember that whole foods are the best sources for fats since they provide more micronutrients, as well as fiber. Avocados and olives are two great examples of nutrient-dense fruits that make great oils but are arguably even better when eaten whole. Both contain plenty of fiber in addition to a variety of vitamins and antioxidants—plus they’re delicious and much more filling than a drizzle of oil! “Eating olives post-workout is a great way to get some extra salt,” says Ziesmer. “And of course, nuts are another great option for eating satisfying foods that are packed with healthy fats. A mix of nuts that includes walnuts is a great source of ALA, an important omega-3, plus you’re getting some protein. Chia and flax are also great additions.”

____________________________

Takeaway

Don’t be afraid to use oil in your cooking, especially when preparing meals for active young athletes. In addition to offering antioxidants and healthy fat, high-quality extra virgin olive oil is the simplest and most cost-effective choice when it comes to selecting an oil to use. Skip aerosol sprays in favor of simply getting a glass spray bottle to fill with olive oil.

Goal-Setting Lesson Video Transcript

Hi. I’m Trevon, Trey, Jennifer. Team USA wheelchair basketball player, paralympian, and true sport athlete. Today, I want to talk to you about goal setting. And there are three things that I would like you to know. First, successful athletes set goals and a planned roadmap. Second, goals should be written down, assessed over time, and changed if necessary. And third, goals need to be challenging in order to be worthwhile. As a freshmen at Edinboro University, I was a part of a team that made the national championship game. And at that time I recognized I was the low man on the totem pole, but I felt in my heart that I knew my dreams were so much bigger than winning a national title. I wanted to make Team USA. I knew what achieving my lofty goal was not going to be easy and that I would need to work hard every day.

So, as a reminder, I created a pyramid of goals that I kept right above my bed. This pyramid reminded me of the accomplishments that I was working towards and visually represented my need to create a solid foundation underneath me before reaching the top. In the bottom roll of my pyramid of goals I listed goals such as obtaining my bachelor’s degree, becoming a scholar athlete award recipient, and becoming an All-American. The middle row listed winning a national title and playing for a professional team. And at the top row, the most challenging of them all, I listed becoming a gold medalist for Team USA.

By understanding that there are smaller stepping stones to achieving my ultimate goal of being on Team USA, I was able to stay motivated and to stay focused on completing the smaller stepping stones fully before moving onto the next one. Now I’ll be the first to admit that not every goal that I listed on my pyramid was accomplished, but seeing my goals every day when I went to bed, I was able to push through the days that I felt like doing nothing in hopes of achieving the bigger picture. Remember, create a clear goal roadmap, assess your goals often, and continue to challenge yourself. I hope that you never stopped dreaming big or reaching for the stars. And I look forward to seeing where your roadmap takes you.

Body Image Lesson Video Transcript

Hi, I’m Kara Winger, Olympic javelin thrower, and true sport athlete. Today I want to talk to you about body image and I have three things I’d like you to know. First, healthy thoughts often lead to healthier bodies. Second, there are varying body types and no one’s body is exactly like another. And third, true beauty goes deeper than the skin. As a multi-time Olympian, I’ve experienced a lot of variation and progression in my training. My coaches and I adapt to my training frequently, all with the goal of supporting my long-term success and health in the sport of javelin. I’m talking to you about body image today because sometimes even with the best of intentions and a common goal in mind, the changes you make to your training habits can prove to be detrimental if made for the wrong reasons. In the lead up to the 2012 Olympic trials, I was told in order to improve my performance on the field, I should try to become a leaner, skinnier version of myself.

So I changed my diet. I went along with what I was being told to do, even though I’d had great success at a slightly heavier weight and higher body fat percentage, and became much leaner than ever before. It seemed like a successful change at first, but I didn’t have nearly the results I’d had before. And I believe becoming leaner than my body naturally wanted to be was what caused my ACL to tear. In the end, it cost me heavily going into the 2012 London games. The takeaway for me, and hopefully for you, is that it’s important to know what works for you and your body and to not compare yourself to others. You should do your research and experiment with your diet to find what makes you feel the best, rather than focusing on what you look like. Today, if I feel like having a chocolate chip cookie, I have one, just not every day.

I’ve learned what a properly balanced meal for my body looks like and I recognize food as the fuel that keeps me throwing. I hydrate and allow myself time to recover. And I listen to and communicate with my body so that I can be the best version of myself. In the end, you are in control of how you see, treat, and respond to your body. We only get one and it’s amazing to discover how many things our bodies can do. Be a true sport athlete. Love who you are in this moment and get excited for all the places your body will take you.

A Good Sport Lesson Video Transcript

Hi, I’m Izy Isaksen, Team USA, Modern Pentathlon, Olympian, US Army Sergeant, and True Sport Ambassador. Today, I want to talk to you about being a good sport. There are three things I’d like you to know. First, real winners act the same toward their opponent, whether they win or lose. Second, follow the rules and be a gracious winner and respectful loser. And third, sportsmanship reveals your true character.

I started competing in Modern Pentathlon eight years after my older sister and three-time Olympian, Margaux Isaksen, began competing. I soon realized that people often compared the two of us. I would overhear spectators and teammates asking, “Who’s the better athlete,” and “Who’s going to beat the other.” Instead of letting outside pressures create a negative experience for us, I chose to practice winning and losing with grace and respect. I know that it would have been easy to let our hyper competitive mindset affect our relationship, but instead we decided to support and cheer for each other, regardless of our own performance. My experience of competing against and being compared to my older sister, taught me to focus on how to perform at my best, rather than putting wasted energy into wishing for others to fail.

I believe that sportsmanship reveals true character. So, no matter what situation I encounter during competition, I know it’s important to always treat people with respect and be a good sport. Remember, be a fierce competitor, find grace in all your victories and losses. And I hope to see you out there.

What Kind of Coach Do You Want to Be? Video Transcript

Edwin Moses: You’re a coach. Maybe what you want is very simple, for everyone to just run in the right direction, score for their own team, to try and try again and again. Maybe you want your athletes to become all stars. You want them to earn trophies, medals, win titles. You want them to reach the highest height their sport allows. And wanting all of that, of course, that’s good. But as every great coach discovers, developing a great athlete means nurturing, nurturing the even greater person within. Truth is, you have even more influence than you know.

You have the ability to affect even deeper change, to take what’s in your hands and do something even more extraordinary. You can be both the coach who provides the skills needed to win the game and the coach who helps them learn and succeed beyond the sport, to become all stars wherever they land in the future, and to enjoy their lives more now, because the confidence and courage they find working with you will stay with them when they need it the most. There are games to be won, lives to change. Coaches have the power to do both.

I’m Edwin Moses, and the lessons I’ve learned through sport have challenged me, guided me, and shaped my life forever. What kind of coach do you want to be?

THE SIMPLE TRUTH: DECODING THE SUPPLEMENT INDUSTRY VIDEO TRANSCRIPT

At first glance, dietary supplements look the same. They seem safe and healthy, but just because the label says a product is a dietary supplement, that doesn’t mean it’s safe. Unfortunately, you can’t tell whether a product is safe or not just by looking at the label. Most vitamins, minerals, fish oil, and other supplements containing nutrients are probably just fine, but supplements are not evaluated or approved by FDA before they are sold. Although it is rare for vitamins or minerals to be contaminated with drugs, there has been at least one case of a vitamin containing an anabolic steroid.

At the other extreme are products that contain drugs, stimulants, anabolic steroids, or other hormones. Even though these are not technically dietary supplements, many of them are labeled as supplements. For example, body-building products sometimes contain anabolic steroids or Selective Androgen Receptor Modulators, known as SARMs, or other hormones. Some pre-workout or energy products contain illegal stimulants like DMAA, ephedra, or other amphetamine-like stimulants. Weight loss products might contain prescription drugs like sibutramine, or hormones, like human chorionic gonadotropin, also known as hCG. All natural or herbal sexual enhancement products might contain hormones or Viagra-like drugs. Products like these can harm your health and career, but they’re for sale online, in some nutrition stores, and they’re labeled as dietary supplements.

When you pick up a supplement, especially one that promises performance enhancement, you don’t know if it belongs in the “Mostly O.K.” pile or in the “Dangerous” pile. After all, two products might look the same, but one might contain just amino acids and other legitimate ingredients, while the other also contains anabolic steroids. Because of this, FDA has issued a warning about certain categories of supplements: body building products, weight loss products, and sexual enhancement products. Be extremely careful when considering a supplement in one of these categories. We strongly recommend that you avoid products in these categories.

Even when FDA tests supplements and finds dangerous ingredients, companies sometimes refuse to recall them. Sometimes, they simply repackage their product and continue selling it under a new name. Just because a product is on a store shelf doesn’t mean it is safe. You need to do your research and be an informed consumer. The dietary supplement industry is enormous. Supplements that appear to be safe could actually be dangerous products in disguise. If you use dietary supplements without doing your research, you may be taking serious risks with your health and your career.
