Olive Oil Q&A with Dr. Sears

Today Dr. Sears is answering your questions about oils and which ones to use.

 

Q: With so many oils in the consumer marketplace, why do you consider olive oil the best of the best? 

A: Olive oil has been used for almost 4000 years and has the most clinical studies to validate its benefits. Extra virgin olive oil (EVOO), not refined olive oil, is the richest of all oils in terms of polyphenols. Most oils come from seeds, but olive oil comes from fruit. This gives olive oil a higher polyphenol content than most other oils. Also, the polyphenols in extra virgin olive are unique as they are very powerful anti-inflammatory agents that can’t be found fruits and vegetables. 

Q: What are your thoughts on some of the newer oils that have hit the market over the past few years like coconut oil, avocado oil, and nut oils? 

A: Only avocado oil has any polyphenols since it comes from a fruit. That said, the amount of polyphenols are significantly less than EVOO and lack the unique structure which gives olive oil its anti-inflammatory properties.

Q: How does someone know what to look for in an olive oil product?

A: It should taste like melted butter on the tip of your tongue but generate a very bitter taste when you flip the oil to the back of your tongue. Clarity and color are important too. If there is very little color it means the oil is refined and many of the polyphenols have been removed.

Q: Are all olive oils the same?

A: No. Authentic olive oil is very expensive to produce. What you’ll find is that some manufacturers will take olive oil and blend them with cheaper vegetable oils to dilute the olive oil and then label it as olive oil. This is why it is estimated that 70% of all olive oil in the U.S. is considered adulterated.

Q: How do you know if olive oil is adulterated?

A: It’s not always easy to tell. You have color and clarity, but this is where choosing a high-quality brand is your best guarantee of quality. When I set out to create Zone Extra Virgin Olive Oil, I sought out a few organic cooperatives in Italy known for their high quality extra-virgin olive oil.  The olives were harvested in late fall, followed by processing over the winter. Then the various processed lots were tested for polyphenol content. Those lots that met our polyphenol requirements were bottled and brought to the U.S. under the Zone brand.

Q: Is there a benefit to using organic olive oil?

A: It takes a lot of energy for plants to produce polyphenols. Once you start using pesticides to increase the production of olives, the plants generally decrease the amount of polyphenols they produce as they don't have to work as hard. This effect is more profound in fruits than vegetables. This is one benefit of using an organic oil because the polyphenol content and benefits are generally higher.

Q: What makes Zone Extra Virgin Olive Oil unique? 

A: We use an organic olive oil cooperative in Umbria, Italy where the oil is bottled on site and sent directly to us. It’s my guarantee that you are getting the best quality oil that Italy can produce that year.

Q: You mention cooking with olive oil destroys the polyphenols. Are there other oils you recommend cooking with instead since olive oil has a low smoke point?

A: Since heat destroys polyphenols the best oil to use for cooking is high-oleic safflower oil which is rich in monounsaturated fat and has a high smoke point. You could also use refined olive oil which has minimal polyphenols but good temperature characteristics. If you want to use EVOO and maximize the polyphenols it contains I recommend drizzling on top of food after its been cooked.

Q: If EVOO has polyphenols do I still need to take my polys? 

A: Yes. I recommend consuming 1000-1500mg of polyphenols per day. The polyphenols in EVOO are unique anti-inflammatory agents which can be one source, but it’s almost impossible to get that many polyphenols in olive oil alone. This is why I recommend consuming about 10 servings of fruits and vegetables per day in addition to getting polyphenols from sources like cocoa, which is good for gut health, and berries such as maqui, which activate key enzymes (AMPK) important for health.

Tofu: Tips and Recipes Ideas

I have been eating tofu for a very long time, much longer than the 30 or so years I have been following the Zone Diet. Back then many of my favorite recipes came from the Tassajara cookbooks by Edward Espe Brown, the celebrated chef from the kitchen at California’s famous Zen Mountain Center, and cookbooks by Louise Hagler, a.k.a. Wendy Louise, a well-known authority on vegetarian cooking who is associated with a community in Tennessee known as The Farm. Those books are still among the best resources for tofu recipes. My mantra has always been if you don’t like something, don’t eat it. Keep this in mind if you’re new to tofu, start slowly by combining it with flavors and foods you like.    Tips and Suggestions    Firm-sprouted tofu is my preference for the Zone Diet. Unlike traditional tofu, which contains significant amounts of both protein and carbohydrate, sprouted has almost no carbohydrates. It’s lighter tasting, refreshing, and very filling.   Freezing tofu results in a chewy, sponge-like texture. I don’t recommend freezing, but some people prefer it when using tofu to substitute for meat in a recipe.    Baked tofu comes in a variety of flavors and makes an excellent quick meal with some vegetables and fruit added. It’s also great in salads.     Tofu made it into the book “The Top 100 Zone Foods” by Barry Sears.    Some recipes call for draining the tofu first. I find that usually isn’t necessary.   Tofu takes on the flavor of whatever is added to it.    Add nutritional yeast flakes to give a cheesy flavor to vegan tofu scrambles and dips. It’s also rich in protein and vitamin B12.   Cherry Vanilla Tofu “Ice Cream”   Tip: This doesn’t freeze or store well, so prepare only the amount you plan to serve immediately.   Using an immersion blender or a food processor blend equal parts of frozen dark cherries and firm tofu, plus some vanilla extract (preferably alcohol-free for best flavor). Serve immediately.  Tofu Scramble  This is great for breakfast, lunch, or dinner, and we’ve even brought it on long day hikes for a snack.   Crumble some firm tofu and stir in a generous amount of seasonings, taking care not to overdo it with the salt. Heat in a well-seasoned or nonstick skillet with a little Zone-friendly oil to the desired doneness.    Optional: If time allows, sauté some chopped onion in the skillet before adding the tofu and seasonings.    My favorite seasoning combination for this dish at my house is onion powder, garlic powder, turmeric, paprika, some oregano or thyme, nutritional yeast flakes, salt, and ground black pepper. The yellow color of the turmeric makes it somewhat like scrambled eggs.   Tofu Veggie Almond Pasta Salad   Dressing: Thin some smooth almond butter by stirring in some water, a little vinegar, and either soy sauce or Bragg’s Liquid Aminos (an unfermented soy sauce found in the health food section of most grocery stores).    Toss together cooked Dr. Sears’ Zone PastaRx Fusilli, tofu cut into cubes, matchstick cut red bell pepper, chopped green parts of scallions (a.k.a. green onions), and the almond butter dressing. Serve immediately or chill to serve later. It will keep well in the fridge for two or three days.   Use your imagination and see what you can come up with.  Experiment and have fun with it. Try using tofu to make cheesecakes, whipped desserts, tofu chocolate pudding, tofu “cream” based soups, tofu pot pie (think chicken pot pie), tofu burgers, tofu burritos, Buffalo tofu (like Buffalo wings), layered Mediterranean dips, tofu “meatballs”, grilled tofu, and more.    Enjoy!
