Penne with Warm Cherry Tomato Vinaigrette Recipe, Spotlight on Chives, Importance of Dedicated Kitchen Shears, Tapping Into Your Creativity and Why Use It or Lose It Is Real

Not every great tomato sauce needs hours of simmering! My warm cherry tomato vinaigrette does double duty—equally delicious over hot noodles and cold salads. And it takes less time to make than boiling the pasta. I’m also sharing the essentials on chives, a delicate yet underused herb, and the best way to chop them. You can also read about how to become more creative and why the exercise adage “use it or lose it” holds true.

Penne with Warm Cherry Tomato Vinaigrette

  • Cherry Tomato Vinaigrette Penne with Warm Cherry Tomato Vinaigrette

    This vinaigrette is also delicious as a topping for bruschetta or pizza. And you can let it cool to room temperature and use it as a dressing on cold dishes as well as salads.

    Ingredients

    • 1 pound farfalle
    • 6 tablespoons extra virgin olive oil, divided
    • 2 shallots, peeled and finely chopped
    • 4 cups cherry tomatoes
    • 2 tablespoon red wine vinegar
    • Coarse salt and freshly ground black pepper to taste
    • 8 ounces fresh mozzarella, cut into small cubes
    • 4 tablespoons fresh chives, chopped

    Directions

    Step 1

    Cook the pasta as directed. While it’s cooking, heat a sauté pan over medium heat, and add two tablespoons of the olive oil. Add the shallots, and cook until softened, stirring frequently. 

    Step 2

    Add in the cherry tomatoes, and cook until they blister, about 5 minutes, pressing down on them with a wooden spoon to release their juices and smash them a bit. Add the vinegar and the rest of the olive oil, and stir. Season to taste with salt and pepper, and remove from the heat.

    Step 3

    Drain the pasta, top with the mozzarella and the cherry tomatoes, and toss well. Garnish with the chives and serve. 

    Yields 4 servings

Healthy Ingredient Spotlight: Chives

Healthy Ingredient Spotlight

Let’s chop up more chives

Consider chives the mild-mannered relative in the allium family of onions, scallions, garlic, and more. Because their flavor is delicate and easily lost, they’re primarily added after any cooking has been done. But there are different types of chives, some more flavorful than others. 

Common chives are the ones you’re most likely to find at the market. They have slender bright green and hollow stalks, sometimes with flowers attached, and their flavor is quite mild.

Chinese or garlic chives are deep green and have flat blades, with a stronger flavor very reminiscent of garlic. They, too, may have flowers attached. 

Siberian or blue chives have exceptionally tall blades yet are almost as mild as common chives yet harder to find. 

Experiment, and consider growing your own to have chives at your fingertips. 

Healthy Kitchen Nugget: Get dedicated kitchen shears

Why you need dedicated kitchen shears

For some kitchen tasks, shears actually work better than a knife, and that’s why you should have at least one pair in your tool drawer. According to the Academy of Nutrition and Dietetics’ Food & Nutrition Magazine, kitchen shears are different from scissors. The blade’s pivot point is farther from the handle, making the shears very strong, perfect for cutting up a whole chicken, for instance. The blades are usually longer and should be removable for easy cleaning, the same safety step you’d take after using a cutting board—but using shears means you may not need to dirty a cutting board as often. 

Use shears to snip chives right over a dish, cut bacon into pieces, and even trim dough after you’ve lined a pie plate. Once you see how versatile they are, you’ll be tempted to buy a variety of shears—dedicated poultry shears, herb shears, and shears with offset blades for cutting at an angle. When possible, choose professional-grade carbon steel blades for durability and coated handles, including a large and oblong bottom handle, for the most comfortable grip. 

For Your Best Health: Tapping into creativity

Tapping into creativity

Researchers at The Ohio State University (OSU) have developed a new method for helping people bring out their creativity by, in part, helping them think like kids again. It’s based on narrative theory and works by recognizing that we’re all innately creative. According to English professor and member of the OSU Project Narrative Angus Fletcher, PhD, who developed the narrative method of training for creativity, “We as a society radically undervalue the creativity of kids and many others because we are obsessed with the idea that some people are more creative than others. But the reality is that we’re just not training creativity in the right way.” 

The method is an alternative to the standard creativity training technique called divergent thinking, which treats the brain as a logic machine, relies on data and information about the problems and successes of the past … and has less-than-optimal results, Dr. Fletcher says. “What it can’t do is help prepare people for new challenges that we know little about today. It can’t come up with truly original actions,” he says. “But the human brain’s narrative machinery can.” 

His method draws on many of the techniques that writers use to create stories, such as developing new worlds in your mind, and perspective-shifting, which is thinking like another member of your work team, for instance. It’s not that the scenarios you dream up will actually happen, Dr. Fletcher says, explaining, “Creativity isn’t about guessing the future correctly. It’s about making yourself open to imagining radically different possibilities. When you do that, you can respond more quickly and nimbly to the changes that do occur.”

The creativity seen in young children is often unintentionally taught out of them by the time they get to middle school, where the focus is on logical, semantic, and memory training. The narrative approach to creativity can help people unlock the creativity they may have stopped using as they progressed through their education, Dr. Fletcher says.

He and Project Narrative’s Mike Benveniste have worked on the narrative method of training for creativity with the United States Army Command and General Staff College, the University of Chicago Booth School of Business, the OSU College of Engineering, and several Fortune 50 companies to teach creativity to their staffs and students. For a more formal evaluation, they’re conducting randomized controlled trials of the creativity curriculum on more than 600 US Army majors at the Command and General Staff College and working with new organizations, such as the Worthington Local School District in Ohio. “Teaching creativity is one of the most useful things you can do in the world, because it is just coming up with new solutions to solve problems,” he says. And you’re never too old to let your imagination run wild.

Fitness Flash: Why “use it or lose it” is real

Why “use it or lose it” is real

Ever wonder why it seems that the less exercise you do, the harder it is to exercise at all? New research offers one possible explanation. Doing less exercise could deactivate the body’s vital Piezo1 protein, according to scientists from the UK’s University of Leeds. Piezo1 is a blood flow sensor. Deactivating it reduces the density of capillaries carrying blood to the muscles, and that restricted blood flow means activity becomes more difficult and can limit the amount of exercise you’re able to do.

The research, published in the Journal of Clinical Investigation, was carried out using mice, but because the Piezo1 protein is also found in people, the same results could occur. As lead author Fiona Bartoli, PhD, a postdoctoral researcher at Leeds’ School of Medicine, says, “Exercise protects against cardiovascular disease, diabetes, depression, and cancer. Unfortunately, many people fail to exercise enough, for reasons such as injury and computer usage. This puts people at more risk of disease. The less people exercise, the less fit they become, often leading to a downward spiral.

“Although many responses to exercise are known, how the benefits of exercise are initially triggered at a molecular level is mysterious. Our study highlights the crucial link between physical activity and physical performance made at this level by Piezo1. Keeping our Piezo1s active by exercising may be crucial in our physical performance and health.”

During the experiment, mice who had their Piezo1 levels disrupted for 10 weeks showed a dramatic reduction in activities like walking, climbing, and running on a wheel activity. Specifically they did fewer wheel revolutions per exercise session and had slower running speeds. The mice didn’t have less desire to exercise but rather less ability.

Adds David Beech, PhD, the study’s supervising author, “Our work sheds new light on how Piezo1’s role in blood vessels is connected to physical activity. A lot was already known about its role in blood vessel development, but far less was known about its contribution to vessel maintenance in adults. Our discovery also provides an opportunity to think about how loss of muscle function could be treated in new ways: If we activate Piezo1, it might help to maintain exercise capability.”

The Ultimate Dog & Human Biscuits Recipe and the Health Benefits of Olive Oil for Cats and Dogs

I was astounded to learn that our furry friends can benefit from extra virgin olive oil just as we do. Here’s what I uncovered, plus an easy recipe for dog treats fit for their owners! With four simple ingredients, you can keep the treat jar filled with wholesome goodness.

Fitness Flash: The Benefits of Olive Oil for Dogs

The Benefits of Olive Oil for Dogs 

Chewy.com is the site for all things pet-related, so it was great to read their informative post on extra virgin olive oil for dogs. Studies show that olive and other oils can help reduce inflammation in dogs and ease the itching associated with allergies, according to Dr. Christopher Reeder, a board-certified dermatologist at BluePearl Veterinary Partners in Franklin, Tennessee. 

Olive oil’s phytonutrients, vitamin E, and omega-3 fatty acids help keep your dog’s skin moisturized and well-nourished. These nutrients also benefit your dog’s coat, adding shine and strength to their hair. Dr. Reeder was quoted as saying that he could see a noticeable increase in luster and shine in the coats of dogs whose diets were supplemented with olive oil. Expect it to take about 30 days, he added. 

Dr. Judy Morgan, a holistic veterinarian and author, added that if you decide to give your dog olive oil, make it extra virgin olive oil because of its rich nutrients and low acidity. According to the Chewy.com report, both vets suggest no more than one teaspoon of olive oil per 20 pounds of body weight per meal (some other vets suggest one teaspoon for every 30-40 pounds), and it can be mixed right in with your fur baby’s regular wet or dry food. Dogs need far fewer calories than we do, so you want to keep amounts small.

Of course, it’s always best to ask your vet before changing your pet’s diet, especially if your dog is being treated for any ailments or conditions. Your vet may suggest starting to supplement with olive oil once a week and gradually moving up to once a day. Never give olive oil—or any other people food—to your dog if he or she is vomiting or having poop issues.

Rover.com points out that fancy dog food brands now tout the addition of healthful fatty acids to their food, but you can add them yourself…and you can use the freshest olive oil available. In terms of other benefits, Rover.com says there’s the possibility that olive oil could offer some of the benefits seen in people, like better brain and heart health. Olive oil’s antioxidants can help protect your dog’s cell membranes from damage by free radicals, making it anti-aging. It may also boost appetite and improve digestion and elimination.

The Benefits of Olive Oil for Cats 

Cats, too, can benefit from olive oil and its monounsaturated fat, according to AnimalWised.com. It may boost their immune system and heart health while lowering their risk for heart disease and diabetes. 

It’s also an easy remedy for constipation, and adding olive oil to your cat’s diet on a regular basis will keep his or her fur shiny and soft. Add just a teaspoon to your cat’s food three times a week, mixing it in until well blended.

Cat owners know how distressing it is when kitty gets a hairball, and cats can get them three or four times a month, according to Hartz, the pet supply company. Their experts suggest mixing one teaspoon of olive oil into your cat’s food for three days straight to help when you sense one. 

The Ultimate Dog & Human Biscuits

  • Ultimate Dog & Human Biscuits Recipe The Ultimate Dog & Human Biscuits

    Look at the label on a box of dog treats and you’ll be shocked at the number of ingredients, some unrecognizable and unpronounceable. My recipe has just four, and you probably already have them in your pantry. These biscuits supply not only healthy olive oil but also three whole grains. I’m reluctant to call them dog biscuits because they’re perfect for people too—top one with a slice of cheese and a teaspoon of fig jam and you’ll never buy boxed “human” crackers again!

    Ingredients

    • 2 cups old-fashioned rolled oats, plus more for topping (optional)
    • 2 cups whole wheat flour, plus more for rolling
    • 2 cups medium-coarse cornmeal 
    • 1/3 cup extra virgin olive oil
    • 1-1/2 cups warm water, or more if needed

    Directions

    Step 1

    Preheat your oven to 350ºF and take out two rimmed cookie sheets. In a large bowl, add the 2 cups of each grain and use a large whisk to combine. Add the olive oil and mix it in with your hands. Add the water, mixing again to make a dough. If it’s too dry, add more water until it comes together. 

    Step 2

    Turn the dough out onto a heavily floured countertop and flour a rolling pin. Divide the dough in two and roll out one half to about 1/4-inch thick. For a prettier cracker to serve to people, sprinkle the tops with a handful of rolled oats and go over the surface with the rolling pin to help set them. If you have a bench scraper, use it to cut the dough into 4-by-2-inch rectangles and then lift them onto a cookie sheet, placing them 1/2 inch apart. (You can also cut them with a blunt knife and transfer them with a large spatula.) Repeat with the remaining dough. All the biscuits should fit on the two sheets. 

    Step 3

    Bake the biscuits for 25 minutes, then reverse their positions in the oven and bake for another 25 minutes until crispy. Store in a cookie jar or tin—they’ll stay fresh for 10-14 days.

    Yields 36 biscuits/crackers

Spinach and Artichoke Dip Recipe, Spotlight on Artichoke, Why You Should Choose Glass for Food Storage, Getting the Recommended Amount of Fruits and Veggies, and The Connection Between Exercise and Brain Health

One of the greatest benefits of following a Mediterranean diet is that the all-important servings of fruits and vegetables are built in. But finding good produce can be a challenge in the dead of winter—this week’s newsletter has ideas to help. My spinach and artichoke dip recipe shows that the comfort foods we crave now can be healthy, too. And though it’s more tempting than ever to park yourself on the sofa, new discoveries on exercise and brain health will make you want to do more than get up to go to the fridge!

Spinach and Artichoke Dip

  • Spinach and Artichoke Dip Spinach and Artichoke Dip

    So much better than store-bought, this dip for chips and crudités also makes a great topping for baked potatoes.

    Ingredients

    • 2 tablespoons extra virgin olive oil, plus more for serving
    • 8 ounces baby spinach leaves, rinsed, patted dry, and coarsely chopped
    • 1/2 cup mayonnaise

    • 1 teaspoon lemon juice
    • 1/2 teaspoon onion powder
    • Salt and pepper to taste
    • Red pepper flakes to taste (optional)

    Directions

    Step 1

    Heat a sauté pan and add the olive oil and the baby spinach a large handful at a time. Sauté until completely wilted and all the liquid has evaporated. Let cool while you proceed.

    Step 2

    In a large bowl, use a spatula to fold together the mayonnaise, sour cream, cream cheese, and yogurt. When blended, add the cooked spinach, artichokes, garlic, dill, lemon juice, and onion powder.

    Step 3

    Season to taste with the salt, pepper, and optional red pepper flakes for an added kick. Drizzle with olive oil before serving.

    Yields about 3 cups

Healthy Ingredient Spotlight: Artichokes

Healthy Ingredient Spotlight

Amazing artichokes

It’s easy to be intimidated by the look of artichokes and easy enough to buy them jarred or frozen when using them in recipes. But a freshly steamed artichoke makes a tasty light lunch or great vegetable-based first course. Native to the Mediterranean region, but also grown in California (where it’s the state vegetable!), artichokes are low in calories and rich in potassium, fiber, and antioxidants. They are also a good source of vitamin C, folate, and magnesium.

Here’s how to steam whole artichokes, according to the California Artichoke Advisory Board: Wash under cold running water, and then pull off any small or discolored petals near the base of the stem. Working one artichoke at a time, cut off the last half inch of the stem and use a vegetable peeler to take off the stem’s outer layer. Next, cut off the top quarter of the artichoke, and place it in a large bowl filled with 4 cups of water and a tablespoon of vinegar or lemon juice, to avoid discoloration. When all the artichokes are prepped, bring 2 inches of water to a boil in a large stockpot, add a steaming rack, place the artichokes on the rack, cover the pot, and steam until a petal near the center pulls out easily, between 25 and 45 minutes, depending on their size. 

To eat, pull off a petal, one at a time, dip it in olive oil, melted butter, or vinaigrette, and pull it through your teeth to get the pulpy portion of the petal. Discard the rest of the petal and repeat until they’re all gone. Use a grapefruit spoon to scrape out the exposed fuzzy layer, or the choke, in the center of the base and discard. What’s left is the sweet heart of the artichoke to enjoy along with the stem. 

Healthy Kitchen Nugget: Glass Storage Containers

Healthy Kitchen Nugget

Choose glass for food storage

If you rely on plastic containers for storing and reheating food, consider the benefits of switching to glass. Even BPA-free plastic has chemicals that can be released into food and have a negative effect on your endocrine system when ingested, a problem you avoid with glass. 

Not only do glass containers last almost indefinitely, but when necessary they can be recycled easily—something that simply isn’t happening with plastics. Look for glass containers that can be stored in the freezer as well as the fridge. 

Try to buy frozen foods packaged in paper, but if your favorites only come in plastic, move the contents of the bag to a glass bowl when you’re ready to defrost them. If it’s necessary to release the food from the packaging, run the bag under cool water for a few seconds, then transfer it. 

For Your Best Health: Importance of fruits and vegetables

For Your Best Health

More fruits and veggies, please!

A startling CDC report released on January 6 showed just how few Americans get the recommended daily 1.5-to-2-cup equivalents of fruit—just 12.3%—and the 2-to-3-cup equivalents of vegetables—only 10%. As part of a healthy diet, these food groups support immune function and help prevent obesity, diabetes, cardiovascular diseases, and even some cancers. Of course, eating fruits and veggies can be harder to do in the winter months when seasonal produce is almost nonexistent and the temptation to eat comfort foods is high. 

Try a two-pronged strategy to boost your intake. First, remind yourself to get these daily servings: Write out a daily diet plan that includes them, so they’ll be front of mind. Next, make shopping for produce more of an adventure. Explore the produce section of your favorite stores to look for new and exotic imported fruits and vegetables—now is a great time to try them. Then check out the frozen foods aisle for selections that were flash frozen at harvest for best flavor, like corn kernels, sweet peas, raspberries, and melon chunks, among others. You’ll get a taste of summer by using them in your favorite warm-weather recipes.

Explaining the exercise–brain health link

A recently published study in Nature got us closer to understanding how exercise slows cognitive aging and why it’s tied to better brain plasticity and less inflammation within the hippocampus. Lab experiments showed that exercise leads to higher levels of a naturally occurring protein in the blood called clusterin. Clusterin can bind to certain cells in the brain and reduce inflammation, a precursor to brain diseases like Alzheimer’s. Researchers studied a small group of people with cognitive impairment who followed a set exercise program for six months and found that they were able to increase the level of clusterin in their blood. One takeaway is that it’s never too late to start getting more physical activity for better brain and body health.

Chilean Empanadas de Pino Recipe, Spotlight on Grinding Your Own Beef, How to Manage Stress and a Link Between Exercise and Brain Health

I love empanadas (if I’m being honest, I love all kinds of meat pies!), but they can seem daunting to make at home. This week’s recipe breaks it down for you. One step that makes every ground meat dish better is grinding the meat yourself, and it’s a snap with a countertop appliance you might already have…as long as you follow one simple step. I’m also sharing two important health discoveries—a creative way to manage stress and a newfound benefit of exercise that’s the latest example of the mind-body link. 

CHILEAN EMPANADAS DE PINO

  • Chilean Empanadas de Pino Chilean Empanadas De Pino

    Stuffed meat pies are part of nearly every culture. This very popular Chilean version builds on the pino—sauteed and beautifully seasoned ground beef—by adding a bounty of other flavors to the filling. 

    Ingredients

    For the dough:

    • 3-3/4 cups unbleached all-purpose flour
    • 1 tablespoon sugar
    • 1-1/2 teaspoons salt
    • 12 tablespoons unsalted butter, cut into 1/2-inch cubes and kept chilled
    • 1-1/4 cups ice water 

    For the filling:

    • 3 tablespoons extra virgin olive oil
    • 3 cloves of garlic, finely minced
    • 3/4 pound of ground beef, preferably chuck 
    • 1 large onion, peeled and finely diced
    • 1 teaspoon ground cumin
    • 2 teaspoons sweet paprika
    • 1 teaspoon dried oregano 
    • 1 teaspoon hot sauce, or more to taste
    • Salt and pepper to taste

    For the assembly:

      null

    • 3 hard-boiled eggs, peeled and quartered lengthwise 
    • 12 brined large green or black olives, pitted 
    • 3/4 cup golden or sultana raisins
    • 1 egg 
    • 1 tablespoon of water

    Directions

    Step 1

    Make the dough: In the bowl of a food processor, pulse the flour, sugar, and salt just until combined. Add the chilled butter and pulse again until the butter bits are about the size of peas—be careful not to overprocess. 

    Step 2

    Transfer the mixture to a large bowl, then add the water, 1/4 cup at a time, stirring and pressing it into the flour mixture with a spatula until you get a cohesive dough (you may not need all the water). 

    Step 3

    Turn the dough out onto a clean, lightly floured work surface and divide into 12 portions. Form each portion into a ball, place the balls on a plate, cover with plastic wrap, and refrigerate for an hour for easier rolling. 

    Step 4

    Prepare the filling: Heat the olive oil in a large frying pan over medium-high heat until it shimmers. Add the garlic, beef, and onion and sauté until the onions are translucent, about 5 minutes. Add the spices, hot sauce, and salt and pepper and cook for another 3 to 4 minutes until the meat is cooked through. Set aside to cool for about 15 minutes.

    Step 5

    Assemble the empanadas: Set out two large baking sheets. Working on a well-floured surface with a well-floured rolling pin, roll one of the dough balls into a 6- or 7-inch circle about 1/8-inch thick. 

    Step 6

    Place 2 heaping tablespoons of the meat mixture in the lower half of the round and arrange an olive, an egg quarter, and a tablespoon of raisins on top of the meat. Fold the upper half of the dough over the filling to create a half-moon shape. To seal it, fold up the edge along the half-moon by about 3/4 inch and crimp all along the way with the tines of a fork for a braided look. Use a large spatula to transfer the empanada to one of the baking sheets. Repeat with the rest of the dough balls. 

    Step 7

    Bake the empanadas: Preheat your oven to 425°F. Make an egg wash by breaking the egg into a small bowl and whisk it thoroughly with the tablespoon of water. Use a pastry brush to lightly brush the tops of the empanadas with the egg wash. Bake on two racks in the oven until golden brown, about 20 minutes, rotating the pans at the halfway mark for even browning.

Healthy Ingredient Spotlight: Grinding Your Own Beef

Healthy Ingredient Spotlight

Grinding Your Own Beef

There’s no better way to elevate ground meat than to grind your own, and it’s not complicated. If you’ve got a Kitchen Aid stand mixer, invest in the grinder attachment (the kit also includes stuffer tubes for making your own sausages!). If you’ve got a food processor, you can simply use the steel blade—it will have a denser texture because it’s mincing rather than grinding.

For the best grind, everything needs to be icy-cold. Prep your meat by cutting it into 1-inch cubes, spreading them out on a baking sheet, covering with wrap, and popping in the freezer for 15 minutes along with your grinder or processor blade. For the grinder attachment, follow manufacturer instructions. For the processor, use the pulse button for the best control, so you don’t end up with a mash instead of a mince.

Healthy Kitchen Tip: Choosing and Using a Pastry Brush

Healthy Kitchen Nugget

Choosing and Using a Pastry Brush

Pastry brushes might seem like a luxury, but a simple natural boar-bristle brush from a company like Ateco is only a few dollars, and the golden finish from painting an egg wash on pastry before baking is more than worth it. Silicone brushes are easier to clean (they can go right in the dishwasher), but a thin egg wash doesn’t coat their bristles well—save silicone for a thicker application, like brushing BBQ sauce on ribs. To clean a natural bristle brush, rinse it under warm water, rub a small amount of dish detergent into the bristles, and rinse again. Blot the bristles with paper towels and let the brush air dry, flat, on a clean dish towel. When the bristles start falling out or if the brush develops any odors, it’s time to replace it. 

For Your Best Health: Making Stress Work for You

Making Stress Work for You

For years, Jeremy Jamieson, PhD, associate professor of psychology and the principal investigator at the University of Rochester’s Social Stress Lab, has been developing ways to rethink how people can deal with stress. Because stress is a normal part of life, it’s better to change how you think about it than to ignore it. For his latest study, published in the Journal of Experimental Psychology: General, college students were taught to see stress as a positive—a tool rather than an obstacle. As a result, they lowered their anxiety levels, scored higher on tests, and responded to academic challenges in a healthier way. 

“We use a type of ‘saying is believing’ approach to learn about the adaptive benefits of stress,” said Dr. Jamieson. For instance, tell yourself that your sweaty palms and racing heart are responses that can energize you to perform well. “Stress reappraisal is not aimed at eliminating or dampening stress,” he explained. “It does not encourage relaxation, but instead focuses on changing the type of stress response: If we believe we have sufficient resources to address the demands we’re presented with—it doesn’t matter if the demands are high—if we think we can handle them, our body is going to respond with the challenge response, which means stress is seen as a challenge, rather than a threat.” Try it and see for yourself!

A Link Between Exercise and Brain Health

A group of scientists led by Bruce M. Spiegelman, PhD, the Stanley J. Korsmeyer Professor of Cell Biology and Medicine at the Dana-Farber Cancer Institute and Harvard Medical School, has just released its latest research on irisin, a hormone produced by muscles during exercise and discovered by Dr. Spiegelman in 2012. After research on human brains found that irisin, named for the Greek messenger goddess Iris, was absent in people who had died of Alzheimer’s disease but was present in others, the team wanted to explore how the hormone might be involved in brain health. 

The most recent study, published in Nature Metabolism, used a variety of lab experiments involving mice to show that irisin can cross the blood-brain barrier and improve cognition—thinking and memory—in both healthy animals and those with a rodent version of Alzheimer’s. These findings suggest that the simple act of exercising could change the course of brain function as we age and lower dementia risk. While it will take research involving humans to learn what types and frequency of exercise are best, these results already suggest that exercise can be as good for your brain as we know it to be for your heart, which should motivate all of us to get moving.
