Taiwanese Chicken Recipe, Spotlight on Ginger, Toasted or Untoasted Sesame Oil, Why Being a Pet Person is Good for You and Why You Could Really Be As Young As You Feel
Part of my mission as the Olive Oil Hunter is to share recipes from all different cuisines and show how they can be made healthier and more flavorful with fresh-pressed olive oil. You might think that Asian stir-fries are synonymous with peanut oil, for instance, but olive oil lends itself beautifully to dishes cooked at high heat and works in perfect balance with traditional Asian ingredients. Case in point: delectable Taiwanese chicken, a one-pan wonder that’s as easy as it is delicious. I’m also sharing research on the health benefits of having a pet and news about a simple blood test that can reveal a person’s biological age, a more accurate health indicator than whatever the calendar says.
Looking for a midweek dinner recipe that’s high in flavor and short on time? This filling stir-fry is the answer. If leeks aren’t available, substitute a large yellow onion. Serve as is or over rice.
Ingredients
2 tablespoons extra virgin olive oil, more as needed
2 tablespoons untoasted sesame oil
4 boneless, skinless chicken thighs, sliced into thin strips
1-inch piece ginger, peeled and sliced into thin coins
12 garlic cloves, peeled
4 scallions, trimmed and cut on the diagonal into 1-inch pieces
2 large leeks, trimmed, triple-rinsed, and sliced into coins
1 red bell pepper, stemmed, seeded, and cut into slivers
8 ounces asparagus, trimmed and cut on the diagonal into 1-inch pieces
1 teaspoon red pepper flakes
1/2 cup Chinese rice wine
2 tablespoons soy sauce
Directions
Step 1
Heat a large wok or frying pan over high heat. When hot, add the olive and sesame oils and the chicken. Use tongs to turn the chicken pieces until they’ve browned on all sides and are just about cooked through. Use a slotted spoon to transfer the chicken to a large bowl.

Ginger
With origins in southern China, ginger (Zingiber officinale) has been cultivated for more than 5,000 years. It was—and still is—widely used as a medicinal, and it is a vibrant flavoring ingredient in cooking. Technically a rhizome (not a root) with a very knobby shape and multiple branches, fresh ginger has a sharp taste that can be too strong for some people, but in cooked dishes, it adds a unique layer of flavor.
Ginger has been used for thousands of years to treat upset stomachs, nausea, colds, and even arthritis. Research attributes its antibacterial, antiviral, and antifungal properties to its hundreds of bioactive compounds like gingerol, the phytonutrient responsible for its distinctive taste.
When buying fresh ginger, look for a smooth peel—if it’s shriveled, it’s old! Store it wrapped in paper towel in the salad drawer, where it will stay fresh for about two weeks. Use a vegetable peeler or a spoon to remove the thin peel—each has its proponents. I’m partial to using a grapefruit spoon because its serrated edges and pointy tip make it easy to get around the nubs.

Sesame Oil—Toasted or Untoasted?
If you already have a bottle of sesame oil in the fridge, do you know what type it is? It’s easy to miss that there are two kinds: untoasted sesame oil, made from raw seeds, and toasted (sometimes labeled roasted) sesame oil, made from toasted seeds. Each delivers a different kind of flavor and is used in different phases of cooking. Use untoasted sesame oil when first cooking foods and toasted sesame oil as a finishing oil—since the seeds were already cooked, you don’t want to cook them twice, which could impart unwanted bitterness to your dish.

Why Being a Pet Person is Good for You
The unconditional love of a pet is reason enough to have one in your life, but the rewards extend to physical as well as mental well-being. Pets help you ease stress and anxiety and can lower the risk for depression, according to experts at UC Davis School of Veterinary Medicine in California, because they provide a calming presence. Caring for a pet also gives people a sense of purpose and adds structure to daily life.
Having a dog in particular helps keep you fit and lowers your risk of heart disease: Over 60% of dog owners meet the recommended weekly amount of exercise compared to just 24% of the general population. Pet owners typically have a lower resting blood pressure than people who don’t own pets and a better quality of life. If having a pet isn’t an option for you, consider other opportunities for animal interactions, like volunteering at a shelter or joining a friend on a walk with their dog.

Why You Could Really Be As Young As You Feel
A recent study from researchers at the Murdoch University Health Futures Institute in Australia found that moderate-intensity exercise can significantly influence appetite-related hormones and perceptions in obese men. It provides new insights into how exercise can aid appetite control and weight management.
According to one of the study authors, Timothy Fairchild, PhD, associate professor at Murdoch’s School of Allied Health, the study confirms their previous work showing the benefits of incorporating regular exercise into daily routines for individuals looking to manage their weight and improve their overall health.
“People understand that exercise helps burn energy. A lot of people assume that exercise also increases hunger and energy intake afterwards,” said Dr. Fairchild. “We have previously shown, using high-intensity exercise, that this is not the case. This latest study shows that even moderate-intensity exercise can have immediate and beneficial effects on appetite control in males with obesity.”
The study not only assessed food intake and appetite but also measured changes in hormones, which help regulate appetite. “Despite a strong focus on weight loss drugs in society at present, this study shows that lifestyle factors still have a strong and relevant role in helping people to live their healthiest life,” Dr. Fairchild added. “In fact, the hormones which have been shown to increase after exercise are the same hormones which the most successful weight loss drugs are mimicking. The added benefit of exercise is that you also receive the physical and mental health benefits of exercise.”
Pasta with Green Sauce Recipe, Spotlight on Winter Greens, Reserving Pasta Water, Chill Out in the Sauna and Resolution Reboot
Ready to shake up pasta night? I’ve got just the recipe—a vibrant winter greens sauce that takes just a few minutes to make. It’s delicious on its own or with your favorite protein. Looking for a way to take the edge off winter? A new study suggests that spending time in the sauna is more than relaxing—it’s good for heart health! And speaking of health, if your New Year’s resolutions are fading from view, the University of New Hampshire has ideas for a reboot.
This is a tasty yet simple prep for pasta, perfect for a weeknight meal. Roasted garlic adds great depth of flavor—spread any leftover cloves on slices of toasted crusty bread. The garlic can be made in advance and kept in the fridge for about a week (after cooling, squeeze out the softened garlic from each clove and store in a sealed jar). I’ve suggested thin spaghetti for this dish, but choose any shape you like, cooked according to package directions.
Ingredients
1 head garlic
5 tablespoons extra virgin olive oil, divided, plus more for drizzling
3 teaspoons coarse sea salt, divided use, plus more to taste
2-ounce chunk Parmigiano-Reggiano, plus more for serving
1/2 teaspoon pepperoncini or red pepper flakes
1/2 teaspoon freshly ground black pepper, plus more to taste
Directions
Step 1
Peel off the papery outer layers from the garlic while keeping the bulb intact. Slice about a 1/2 inch off the top; you can trim the roots but don’t cut them off or the cloves won’t hold together. Place the garlic cut side up on a piece of parchment paper, then drizzle 1/2 tablespoon of olive oil on the exposed cloves. Fold the long sides of the parchment paper over the garlic, then fold the ends underneath to make a packet. Place on a rimmed sheet pan and roast for 45 to 60 minutes, until the cloves are golden and soft and start to shrink away from the peel.
Step 2
Prepare an ice bath by filling a large bowl with ice and cold water; set aside. Fill a stockpot with 4 quarts of water and bring to a boil. Add 2 teaspoons of salt and the spinach. Cook for 2 minutes, then use a spider skimmer or slotted spoon to move the spinach to the ice bath (this chill-down helps retain its color), leaving the pot of boiling water on the stove.
Step 3
Add the pasta to the pot of boiling water and cook until tender, about 10 minutes. When the pasta is half cooked, prepare the sauce. Pare any rind off the cheese, cut it into cubes, place in your food processor, and pulse until the cheese is nearly a powder. Remove 1/4 cup of cheese from the work bowl and set aside. Add in the spinach, 6 cloves roasted garlic, the pepperoncini or red pepper flakes, the remaining salt, and the black pepper. Process until smooth, adding 1/4 to 1/2 cup of liquid from the pasta pot if needed.
Step 4
Drain the pasta, transfer it to a large bowl, and toss with the sauce, thoroughly coating it. Serve each portion with a drizzle of olive oil and a sprinkle of the reserved cheese.

Winter Greens
Spinach is just one of the many delicious greens available this season. Kale, especially the milder lacinto kale; collard, beet, mustard, and turnip greens; escarole (wonderful in my Italian wedding soup); and Swiss or rainbow chard are other flavorful varieties, delivering vitamins such as A, C, and K; the B vitamin folate; minerals including calcium, potassium, and iron; and a bounty of phytonutrients.
Winter greens make great salads and side dishes. Heartier greens, like kale and collards, do take longer to cook. If you want to try them for my Pasta with Green Sauce, remove any hard ribs and let them boil for 5 minutes before proceeding with the recipe.

Reserving Pasta Water
This simple hack, an essential part of classic pasta dishes like cacio e pepe, is a flavorful way of thinning sauces. Pasta water not only adds some salt but also some starch, which lends creaminess to a sauce as it emulsifies with the olive oil in a recipe. Simply ladle out a cup or so of the cooking liquid before draining pasta and use as needed. To really amp up the flavor, experiment with pasta imported from Italy because of the excellent flours used.

Chill Out in the Sauna
Most of us think of the cozy warmth of a sauna as a great way to relax. Now, thanks to a study done by researchers from Lulea University of Technology and Umeå University in Sweden and the Montreal Heart Institute’s EPIC Centre in Canada, we know that the benefits of sauna time go far beyond relaxation to include lower blood pressure, higher energy levels, and improved sleep, adding up to better physical and mental health.
The study compared the demographic characteristics, health status, and lifestyle habits of sauna users and nonusers. People who frequented saunas one to four times a month had fewer diagnoses for hypertension. They also reported less pain, higher happiness and energy levels, and more satisfying sleep.
When people are in a sauna, their core temperature rises so they sweat more to cool down, a process facilitated by increased blood flow. When blood vessels are exposed to sustained heat for several minutes, they dilate to boost blood flow, thereby removing heat from the body and cooling the body down. “In time, this dilation mechanism helps increase blood vessel elasticity and may thus explain the lowering of blood pressure,” said Earric Lee, PhD, a postdoctoral researcher at the EPIC Centre.
After exposure to heat, the body begins to cool but does not merely return to the baseline homeostatic temperature: It actually drops even lower. As a result, sleep quality increases, as people enter the same state as when they start to fall asleep and their body temperature drops.
Endorphins are also released into the bloodstream when the body is exposed to heat. “This may be one of the reasons why we feel so good after a sauna,” said Dr. Lee. “That same sensation of well-being may mask our aches and pains. They may not disappear completely, but we do feel better.”
Dr. Lee wants to go a step further and find out whether sauna use may also benefit cardiac rehabilitation patients. The idea is to place patients suffering from heart disease in a sauna immediately after exercise and determine, based on their response, whether heat multiplies the positive effects of physical activity.
“While I was doing my doctorate in Finland,” said Dr. Lee, “we conducted a study with sedentary individuals presenting cardiovascular risk factors. Even though the study period was only eight weeks long, we noted a decrease in blood pressure, improved cardiovascular condition, and lower cholesterol levels.” He’d now like to revisit this protocol and apply it to cardiac rehabilitation patients for 12 weeks to see whether they reach improved outcomes over those of individuals who only follow the cardiac rehabilitation program without going to the sauna.

Resolution Reboot
Having a hard time keeping New Year’s resolutions going? That’s perfectly normal, according to Katie Godshall, LCSW-BACS, a clinical assistant professor in the College of Health and Human Services at the University of New Hampshire and an expert in the field of mental health—change can be hard. But before throwing in the towel, it’s important to remember why those resolutions were important to you in the first place.
“Don’t get overwhelmed with feelings of guilt and disappointment if the resolutions aren’t working for you,” said Dr. Godshall. “The most important thing is to be kind to yourself. Chances are your resolutions were focused on healthier choices for the new year, so rather than piling on the self-doubt and other bad feelings, take a moment to look at why your resolutions may not be working.”
Resolutions usually start out with a lot of motivation and drive, but over time the momentum can slow, causing people to quit altogether. Before giving up, ask yourself “what, how, and why” questions. “Make sure you’re being realistic,” she advised. “Ask yourself, what are you trying to accomplish? How are you trying to get it done? Why is it important? And make sure you’re not tackling too much too soon. Be honest with yourself, and if it’s not working for you, it’s perfectly fine to step back, reassess, and adjust—otherwise you’re doing yourself a disservice and may be just as unhappy sticking with the resolutions as you would be if you quit.”
Dr. Godshall suggests reframing your view. Think of it not as quitting but as resetting your goals. You might even decide to pick another time of year that may better fit your goals. “We’re just coming off the holidays, filled with indulgence and chaotic schedules, so some people may already be starting off on a bad foot,” said Dr. Godshall. “Maybe use this time to prepare and set yourself up for success. For example, research good running sneakers, do some stretching, and opt to start a running routine in the spring, when the weather is nicer.”
Here are her tips for a resolution reboot:
Examine and reset goals. Maybe your resolution is too ambitious. Make sure it’s flexible enough to fit into your daily schedule.
Be kind to yourself. Rethinking goals is still moving forward—it’s not giving up, it’s adjusting, so avoid feeling guilty or thinking you’ve failed.
Resist perfection. Resolutions are supposed to help, not bring you down. Redirect and focus on what works best for you.
Find a resolution partner. Having someone—a friend, family member, or coworker—to collaborate with can give you external reliance and accountability.
Celebrate success. Recognize small milestones. Focus on your progress even if the road was bumpy.
Pistachio Cake with White Chocolate Cream Recipe, Spotlight on Pistachios, Grinding Nuts, Protecting the Brain, and New Stroke Prevention Guidelines
Looking for a sweet change from that box of chocolates for Valentine’s Day? My cake combines tender pistachio chiffon layers and a rich but not overly sweet cream filling. It’s a showstopper to cap off any celebration. While most of the attention around February 14 is on the heart, I’m sharing important advice for nurturing your brain to stave off two health threats—dementia and stroke.
Pistachio and white chocolate are two luscious ingredients whose unique tastes enhance each other. This cake is not only delicious but can also be up made up to two days in advance. For the white chocolate, choose a brand that’s 35% cacao and in bar or disc form, not chips, which won’t melt smoothly.
Ingredients
For the cake:
4 large eggs
1 cup cake flour
1/2 cup ground unsalted pistachios (see Healthy Ingredient Spotlight and Quick Kitchen Nugget in weekly newsletter)
1/2 teaspoon baking powder
1 cup sugar, divided use
1/2 cup extra virgin olive oil
1 teaspoon vanilla
1/3 cup room-temperature water
1/4 teaspoon fine sea salt
1/2 teaspoon cream of tartar
For the filling and garnish:
4-1/2 ounces white chocolate
1-1/2 cups heavy cream, divided use
2 tablespoons confectioners’ sugar
2 pints raspberries
1/4 cup unsalted pistachios, coarsely chopped
Optional: edible dried rose petals
Directions
Step 1
Make the cake: Separate the yolks from the whites when the eggs are cold and allow them to come to room temperature.
Step 2
Place one of your oven racks in the center of the oven; preheat to 325°F. Line a 17-by-13-inch rimmed sheet pan with parchment paper (do not grease it).
Step 3
In a small bowl, whisk together the flour, ground pistachios, and baking powder; set aside. In a large bowl or the bowl of a stand mixer fitted with the whisk attachment, beat the egg yolks and a 1/2 cup of the sugar at medium speed until pale, about 2 minutes. Mix in the olive oil, vanilla, and water. On low speed, fold in the flour mixture. If you have only one stand mixer bowl, transfer the batter to another bowl and wash the stand mixer bowl and whisk thoroughly—any fat will prevent the egg whites from whipping.
Step 4
In a separate large bowl or the cleaned bowl of the stand mixer fitted with the whisk attachment, beat the egg whites on medium-low speed until foamy, about 30 seconds. Add the salt, cream of tartar, and remaining 1/2 cup sugar. Slowly increase the speed to high and beat until you achieve a glossy meringue that holds firm peaks, 5 to 8 minutes depending on your mixer.
Step 5
Add a 1/4 of the meringue to the batter and mix thoroughly to incorporate (this will lighten it). Add the remaining meringue in 3 batches, gently folding after each addition until only a few streaks of meringue remain (err on the side of undermixing to keep the batter billowy).
Step 6
Transfer the batter to the sheet pan and smooth out with a large offset spatula; be sure to get into the corners of the pan. Bake for 10 minutes, then rotate the sheet pan in the oven for more even baking. Continue baking until the top is golden brown and springs back when gently pressed, 10 to 15 minutes more.
Step 7
Remove the sheet pan from the oven and slide the cake and parchment paper onto a wire rack to cool. After 10 minutes, invert the cake onto another rack and gently peel off the parchment paper. Let the cake cool completely.
Step 8
Make the filling: Melt the white chocolate and a 1/3 cup heavy cream in the microwave in 1-minute increments at power 4 until just about melted. Use a small spatula to stir until completely smooth; let cool to room temperature.
Step 9
Place the rest of the cream in a large bowl or the clean bowl of the stand mixer fitted with the whisk attachment. Whisk until thick, then with the mixer running on low speed, add the cooled melted white chocolate. Increase the speed and whip until peaks form. Chill in the fridge for 15 minutes for easier spreading.
Step 10
While the cream is chilling, trim the edges of the cake. Sprinkle on the confectioners’ sugar and use your hands or a pastry brush to spread it out. Cut the cake into 3 sections, each about 12 inches long and just over 5 inches wide. Rinse the raspberries and pat them dry. Reserve 20 berries and lightly mash the rest in a bowl.
Step 11
To assemble the cake, place one layer on a rectangular serving plate and spread on 1/3 of the filling, then press in half the mashed berries. Repeat with another layer of cake, another 1/3 of the cream, and the rest of the mashed berries. Top with the final cake layer and spread the rest of the cream on top. Garnish with the whole berries, chopped pistachios, and, if desired, rose petals.

Pistachios
With good amounts of protein, fiber, healthy fats, potassium, B vitamins, and assorted phytochemicals, pistachios are great to include in dishes—from baked goods to salads—and make a smart snack.
For baking, choose unsalted pistachios and, to bring out their flavor without losing their green color, toast for just a few minutes at a low temperature. Preheat your oven to 300°F. Place the shelled pistachios on a rimmed sheet pan and into the oven for about 5 minutes. Once the nuts cool down a bit, rub them between your hands to remove some of the skins. Wait until the nuts reach room temperature to grind or chop them as needed for your recipe.
Quick Kitchen Nugget
Grinding Nuts
As with almonds, ground pistachios are easy to make at home in a nut or coffee bean grinder. I prefer a grinder and working in batches to using a food processor, unless the goal is to achieve more of a nut butter. To keep ground pistachios light and powdery for a cake, add nuts until the grinder is about half full and process in spurts. Stop the machine as soon as you no longer hear any chopping noise. It typically takes about 2 ounces of shelled nuts to yield a 1/2 cup of nut flour.

Protecting the Brain
A recent study supported by the National Institutes of Health and published in Neurology®, the medical journal of the American Academy of Neurology, looked at a new potential harm of processed and unprocessed red meat: negative impacts on brain health.
“Red meat is high in saturated fat and has been shown in previous studies to increase the risk of type 2 diabetes and heart disease, which are both linked to reduced brain health,” said study author Dong Wang, MD, ScD, of Brigham and Women’s Hospital in Boston. “Our study found processed red meat may increase the risk of cognitive decline and dementia, but the good news is that it also found that replacing it with healthier alternatives, like nuts, fish, and poultry, may reduce a person’s risk.”
The researchers defined processed red meat as bacon, hot dogs, sausages, salami, bologna, and other processed meat products, and unprocessed red meat as beef, pork, lamb, and hamburger. A serving of red meat is 3 ounces, about the size of a deck of cards.
The first part of the research involved 133,771 people with an average age of 49 who did not have dementia at the start of the study. Participants completed a food diary every 2 to 4 years, listing what they ate and how often, enabling the researchers to calculate how much red meat each person ate on average per day. They were followed up to 43 years. Of this group, 11,173 people developed dementia.
To see the effects of processed red meat, they divided the participants into three groups: The low group ate an average of fewer than 0.10 servings per day (think of this as less than 1 serving a week); the medium group ate between 0.10 and 0.24 servings per day (less than 1 to less than 2 servings a week); and the high group, 0.25 or more servings per day (roughly 2 or more servings a week). After adjusting for age, sex, and other risk factors for cognitive decline, researchers found that participants in the high group had a 13% higher risk of developing dementia compared to those in the low group.
To see the effects of unprocessed red meat, they compared people who ate an average of less than half a serving per day to people who ate 1 or more servings per day; they did not find a difference in dementia risk.
The researchers also looked at both subjective cognitive decline and objective cognitive function. Subjective cognitive decline is when a person reports memory and thinking problems before any decline is large enough to show up on standard tests. Objective cognitive function, which can identify decline, is how well your brain works to remember, think, and solve problems. To evaluate meat’s potential effects on subjective cognitive decline, they looked at a different group of 43,966 participants with an average age of 78 who took surveys rating their own memory and thinking skills twice during the study.
After adjusting for age, sex, and other risk factors for cognitive decline, the researchers found that participants who ate an average of 0.25 or more servings per day of processed red meat had a 14% higher risk of subjective cognitive decline compared to those who ate an average of fewer than 0.10 servings per day. They also found people who ate 1 or more servings of unprocessed red meat per day had a 16% higher risk of subjective cognitive decline compared to people who ate less than a 1/2 serving per day.
To evaluate meat’s potential effects on objective cognitive function, the researchers looked at a third group, 17,458 female participants with an average age of 74 who took memory and thinking tests four times during the study.
After adjusting for risk factors, the researchers found that eating more processed red meat was associated with faster brain aging in global cognition with 1.61 years with each additional serving per day and in verbal memory with 1.69 years with each additional serving per day.
Finally, researchers found that replacing 1 serving per day of processed red meat with 1 serving per day of nuts and legumes was associated with a 19% lower risk of dementia and 1.37 fewer years of cognitive aging. Making the same substitution for fish was associated with a 28% lower risk of dementia and replacing with chicken was associated with a 16% lower risk.
“Reducing how much red meat a person eats and replacing it with other protein sources and plant-based options could be included in dietary guidelines to promote cognitive health,” said Dr. Wang.
A limitation of the study was that it primarily looked at white health care professionals, so the results might not be the same for other race, ethnic, and non-binary sex and gender populations. “More research is needed to assess our findings in more diverse groups,” he concluded.

New Stroke Prevention Guidelines
Each year, over half a million Americans have a first stroke. According to the American Stroke Association, a division of the American Heart Association, up to 80% of strokes may be preventable. Its “2024 Guideline for the Primary Prevention of Stroke” outlines steps that people and their doctors can take to protect against this devastating brain event, including screening people for stroke risk factors and increasing the public’s awareness and knowledge about healthy lifestyle changes to reduce the risk.
“The most effective way to reduce the occurrence of a stroke and stroke-related death is to prevent the first stroke—referred to as primary prevention,” said the guideline writing group chair, Cheryl D. Bushnell, MD, MHS, FAHA, professor and vice chair of research in the Department of Neurology at Wake Forest University School of Medicine in Winston-Salem, NC. “Some populations have an elevated risk of stroke, whether it be due to genetics, lifestyle, biological factors, and/or social determinants of health, and in some cases, people do not receive appropriate screening to identify their risk.”
The guideline replaces the 2014 version and provides evidence-based recommendations for strategies to support brain health and prevent stroke throughout a person’s life. “This guideline is important because new discoveries have been made since the last update 10 years ago. Understanding which people are at increased risk of a first stroke and providing support to preserve heart and brain health can help prevent a first stroke,” said Dr. Bushnell.
Modifiable risk factors for stroke, such as high blood pressure, overweight and obesity, elevated cholesterol, and elevated blood sugar, can be identified with physical exams and blood tests. These conditions, the guideline states, should be addressed with healthy lifestyle and behavioral changes and may include medications. A new recommendation is to consider GLP-1 receptor agonist medications, which are FDA-approved to reduce the risk of cardiovascular disease in people who are overweight or obese and/or have type 2 diabetes.
The most common lifestyle behaviors that can help reduce stroke risk include healthy nutrition, regular physical activity, avoiding tobacco, getting healthy sleep, being at a healthy weight, controlling cholesterol, and managing blood pressure and blood sugar. The guideline recommends that adults with no prior cardiovascular disease, as well as those with increased risk, follow a Mediterranean dietary plan. Mediterranean dietary programs have been shown to reduce the risk of stroke, especially when nuts and olive oil are eaten.
The guideline also includes some new specific recommendations for women. Health professionals should screen for conditions that can increase a woman’s risk of stroke, including use of oral contraceptives, high blood pressure during pregnancy, other pregnancy complications such as premature birth, endometriosis, premature ovarian failure, and early onset menopause. For instance, treating elevated blood pressure during pregnancy and within six weeks of delivery is recommended to reduce the risk of maternal intracerebral hemorrhage.
“Most strategies that we recommend for preventing stroke will also help reduce the risk of dementia, another serious health condition related to vascular issues in the brain,” said Dr. Bushnell.
According to the American Stroke Association, it’s also important to remember the warning signs of stroke with the acronym FAST: Face drooping, Arm weakness, Speech difficulty, Time to call 911.
A large body of evidence shows that daily consumption of EVOO can significantly reduce the risk of cardiovascular disease (CVD). Part I of this two-part series highlighted the contributions of oleic acid (OA). The other bioactive components of EVOO that protect against CVD are its more than 30 polyphenols.
Factors that contribute to CVD include oxidative stress, inflammation, cholesterol, blood-vessel function, and high blood pressure (hypertension). Below, we’ll look closely at the mechanisms by which polyphenols work in the body to modify and improve these factors.
What are polyphenols? Polyphenols are naturally occurring substances in many plants and fungi. Most polyphenols are antioxidants, which means they help neutralize chemical compounds formed in the body that can damage cells. Hydroxytyrosol (HT) has been identified as the polyphenol in EVOO that is essential in the prevention of CVD.
HT combats oxidative stress
Oxidative stress can cause cell mutations and has been identified as an underlying cause of multiple aspects of CVD. Injured tissues release ions—charged particles—that bind to oxygen, creating an excess of unstable molecules. As an antioxidant, HT directly neutralizes these unstable molecules, or reactiveoxygen species (ROS). HT has also been shown to inhibit the cell damage produced by ROS and to enhance the antioxidant abilities of cells in the blood vessel walls.
Lowers inflammation
HT can block some of the processes that signal for cells to mount an inflammatory response. In this way, HT reduces the impact of inflammatory substances that are linked to oxidative stress as well as to impaired blood vessel function, a key risk factor for CVD.
Reduces “bad” cholesterol and improves “good”
Polyphenols reduce the amount of small molecules of LDL (“bad” cholesterol), which do the most damage. Polyphenols also help prevent LDL from forming plaques that build up in the arteries, or atherosclerosis. In a 3-week clinical trial, HDL (“good” cholesterol) functioning improved significantly in healthy patients who consumed high-polyphenol EVOO, compared with low-polyphenol EVOO.
Protects the blood vessel lining and lowers blood pressure
Polyphenols help prevent damage to the endothelium, the inner lining of the blood vessel walls, by increasing the production of nitric oxide (NO), a vasodilator—a substance that relaxes the blood vessels. By enhancing the production of NO, polyphenols can improve endothelial function, protect against arterial stiffness, and lower blood pressure.
