Peruvian Purple Potato Salad Recipe, Spotlight on Potatoes, The Other “Utility” Knife and Spiritual Fitness for Brain Boosts and Protecting Your Skin

This week’s Olive Oil Hunter Newsletter delivers the goods with a delicious and surprising twist using richly colored Peruvian purple potatoes. And their beauty is more than skin deep!

Note: Specialty potatoes are often available online if they’re not at your local market. And if you can’t find purple ones, you can substitute any brightly colored variety.

PERUVIAN PURPLE POTATO SALAD

  • PERUVIAN PURPLE POTATO SALAD Peruvian Purple Potato Salad

    The beauty of these potatoes is more than skin deep—they’re rich in antioxidants. Leave on the skins for maximum nutritional benefits. 

    Ingredients

    • 2 pounds Peruvian purple potatoes, scrubbed 
    • 3 tablespoons Pear Balsamic Vinegar
    • 2 teaspoons Dijon mustard
    • 1/2 teaspoon salt, plus more to taste 
    • 1/4 teaspoon black pepper, plus more to taste
    • 1/2 cup extra virgin olive oil
    • 1/2 cup Kalamata olives, pitted and roughly chopped
    • 1/4 cup red onion, peeled and diced
    • 1 jalapeño pepper, stemmed, seeded, and finely diced (optional) 
    • 1/2 yellow or orange bell pepper, stemmed, seeded, and diced
    • 3 tablespoons each chopped fresh cilantro, parsley, and chives 

    Directions

    Step 1

    Boil the potatoes in salted water until just tender—20 minutes or so, depending on their size, but don’t overcook. Drain, let cool slightly, and quarter them. Transfer to a large bowl. 

    Step 2

    In a small bowl, combine the vinegar, mustard, salt, and black pepper. Slowly whisk in the olive oil until the mixture emulsifies. Pour the vinaigrette evenly over the potatoes while they’re still warm. Gently fold in the olives, onion, jalapeño (if using), bell pepper, and herbs. Season to taste with more salt and black pepper. 

    Yields 4 to 6 servings

Potatoes Get More Colorful

Americans don’t get enough fruits and vegetables, except when it comes to our beloved potatoes—we each eat about one pound every week! Potatoes are considered starchy because they’re calorie-dense, but a medium-sized potato, skin on, still delivers on nutrition: 35% of a day’s vitamin C needs, 30% of vitamin B6, and 25% of potassium, plus 4 grams of fiber and 5 of protein. Most of those nutrients are in the skin, so keep it on, even when making mashed.

Potatoes have been getting more and more colorful, and each color is a sign of its antioxidant content, just as it is for berries. Beyond Yukon golds and red-skinned potatoes, purple varieties are becoming easier to find. Even the US Agricultural Research Service got into the act by creating Huckleberry Gold, with a purple jacket, a fine-textured yellow flesh, and a significantly higher level of antioxidants than those Yukons.

As with pasta, it’s what you put on your potato that counts. Cleveland Clinic registered dietitian Andrea Dunn suggests: “Try a drizzle of olive oil with chives instead of sour cream, butter, and salt.”

Healthy Kitchen Tip: Grapefruit Knife

Healthy Kitchen Nugget

The Other “Utility” Knife

Think of it as the unsung hero in your utensil drawer (chances are, it’s hidden somewhere in the back). The grapefruit knife, often the same length as a dinner knife, is unique because both edges are serrated and the blade itself is curved. This makes it not only ideal to cut out the sections of a citrus half (oranges and lemons as well as grapefruit), but also to stem peppers, from jalapeños to bells, and even strawberries, with a neat edge. It’s especially handy when you want to keep a pepper intact for stuffing, since you can maneuver the blade around the inside to cut away the ribs. If you don’t already have one, a grapefruit knife is just a few dollars, and you can find many options online.

Spiritual Fitness for Brain Boosts

According to researchers Dharma Singh Khalsa, MD, of the Alzheimer’s Research and Prevention Foundation in Tucson, and Andrew B. Newberg, MD, of the Marcus Institute of Integrative Health at Thomas Jefferson University in Philadelphia, “spiritual fitness,” a new concept in medicine that centers on psychological and spiritual well-being, may reduce multiple risk factors for Alzheimer’s disease (AD).

Spiritual fitness weaves together basic, psychological, and spiritual well-being, which is often practiced independent of religion. Drs. Khalsa and Newberg analyzed existing research for their review, “Spiritual Fitness: A New Dimension in Alzheimer’s Disease Prevention,” published in the Journal of Alzheimer’s Disease, and found positive connections between spiritual fitness and brain health. Psychological well-being includes having a purpose in life, and according to one study, people who feel this strongly are 2.4 times more likely to remain free of AD than people who don’t. In another study, having a purpose in life was linked to better cognitive function as people age.

Because stress, with its physical, psychological, and emotional effects, may elevate AD risk, stress management is important to help reduce it. Drs. Khalsa and Newberg highlighted a practice called Kirtan Kriya, a 12-minute singing meditation that involves four sounds, breathing, and repetitive finger movements. It not only helps improve sleep, decrease depression, increase well-being, and improve mood, but also may increase blood flow to areas of the brain involved in cognition and emotional regulation. Practiced long-term, it may increase grey matter volume and decrease ventricular size to help slow brain aging.

“Mitigating the extensive negative biochemical effects of stress with meditation practices, in tandem with the creation of heightened levels of spiritual fitness, may help lower the risk of AD. Small shifts in one’s daily routine can make all the difference in AD prevention,” Dr. Khalsa and Dr. Newberg conclude.

Avoiding Another Kind of Injury

You know all about warming up and stretching before exercise to avoid injury, but you might not realize the risk that the sun poses, especially on hot, sunny days, and not only in terms of dehydration. Your skin is especially vulnerable to sunburn when you’re active outdoors, especially when you forget the sunscreen. In addition to being a risk factor for skin cancer, sunburn affects thermoregulation and the dissipation of excessive heat—that also makes it a risk factor for heat-related illnesses, according to Frank Perna, EdD, PhD, of the National Institutes of Health, and David Conroy, PhD, of the Penn State Cancer Institute, writing for the American College of Sports Medicine. Even though sweating plays the vital role of cooling you off, it also shortens the time it takes UV exposure to cause a sunburn.

Consider these smart precautions:

  • Protect your skin with a variety of approaches—sunscreen, protective clothing, and working out in shady conditions and/or avoiding peak UV times.
  • Apply sunscreen regularly, and don’t be skimpy with it. “Some dermatologists recommend higher SPF sunscreen for athletes because of sweat effects on photosensitivity and the common finding that most people only apply about half the recommended amount of sunscreen,” write Drs. Perna and Conroy. For less mess and to be sure it’s properly absorbed, apply it before going outside. The CDC recommends using a broadband sunscreen with SPF of 15 or greater and reapplying it every 80 minutes or every time you towel off. Carry sunscreen with you even if you don’t have specific plans for outdoor exercise—you never know when someone will toss a Frisbee your way at the park.
  • Choose exercise apparel with a UPF rating to shield skin. Add a hat to protect your scalp. And remember to wear sunglasses with UV protective lenses—sunlight can accelerate cataracts.

Grilled Halloumi Over Salad Recipe, Spotlight on Cheeses That Can Take the Heat, When to Wash Veggies and The Link Between Exercise and Sleep

Who doesn’t love a gooey grilled-cheese sandwich? But what can you do when you want cheesy goodness without the bread? The delicious answer is cheese varieties that hold their shape under heat.

GRILLED HALLOUMI OVER SALAD

  • GRILLED HALLOUMI OVER SALAD Grilled Halloumi Over Salad

    I’m a huge fan of halloumi, a brined goat’s milk cheese from Cyprus. Because it has a high melting point, this firm, somewhat salty cheese can be grilled directly on the grate. You can skewer chunks along with your favorite veggies or simply grill slices and serve them with the refreshing seasonal salad in this recipe.

    Ingredients

    • 4 tablespoons extra virgin olive oil, divided
    • 1 tablespoon best-quality red wine vinegar 
    • 1 teaspoon fresh oregano, chopped, or 1/2 teaspoon dried oregano 
    • Kosher salt to taste
    • Freshly ground black pepper to taste
    • 8 ounces cherry tomatoes, halved 
    • 1 cucumber, diced
    • One head romaine lettuce, washed, dried, and torn 
    • 12 brined Kalamata olives, drained, pitted, and halved 
    • 1/2 cup loosely packed flat-leaf parsley, coarsely chopped
    • 12 ounces of halloumi, cut crosswise into 1/3-inch-thick slices 
    • 4 tablespoons Greek yogurt (optional)

    Directions

    Step 1

    Make the salad: In a bowl, whisk together 2 tablespoons of the olive oil, the red wine vinegar, oregano, salt, and pepper. Add the tomatoes, cucumber, lettuce, olives, and parsley. Toss gently to coat the vegetables with the dressing and divide evenly on four plates.

    Step 2

    Pour the rest of the olive oil onto a rimmed sheet pan and gently coat both sides of each cheese slice. On a medium-hot grill, grill the cheese for 1 to 2 minutes per side, turning with tongs or a thin-bladed spatula. (Work in batches if necessary.) 

    Step 3

    Top each salad plate with equal amounts of the grilled cheese and add a dollop of yogurt, if desired. Serve immediately. 

    Yields 4 servings.

More Cheeses That Can Take the Heat

Halloumi isn’t the only fresh, semi-firm cheese that can be cooked without melting. Another great one is paneer, the cheese used in Indian cuisine, most famously the creamy spinach dish saag paneer. It’s readily available at many markets, not just specialty shops. And from frigid Finland comes leipäjuusto, popular there at breakfast, according to the experts at the magazine Culture: The Word on Cheese. These cheeses will soften when grilled, but they won’t break down and melt thanks to their low acid content. That’s also the reason you may hear a squeaking sound as you bite into them!

When Exactly to Wash Veggies

While most concern over food contamination centers on raw meat, vegetables as well as fruits can have organisms you want to keep out of the kitchen. Here are some tips from the FDA and the University of Maine Cooperative Extension to stay safe.

Start by choosing produce that isn’t bruised or damaged. If shopping for precut foods, like fruit chunks or bags of lettuce, make sure they’ve been kept refrigerated or on ice at the store, and get them into the fridge as soon as you get home. If a food gets marred before you’ve had a chance to use it, cut off the affected areas before preparing or eating it.

There are also steps to take with freshly harvested produce, whether from your own garden or a farmers’ market. Washing off produce can help reduce microorganisms. There’s no need to use soap or a special produce wash—just gently rub the produce while holding it under plain running water. Do make sure the water is no more than 10 degrees Fahrenheit colder than the food, or else any pathogens could get drawn in through the stem (if there is one). Because excess water can lead to faster molding or rotting, be sure to thoroughly dry your produce with clean paper towels before storing it in the fridge. To store produce without washing it first, shake, rub, or brush off any garden dirt with either a clean, soft brush or a clean, dry paper towel before you bring it inside if possible. Then place the produce in a plastic bag or container to prevent any risk of contamination to other foods in your fridge. For a list of which produce should be washed and which produce should be wiped clean, check out this resource page from the University of Maine Cooperative Extension.

Always rinse produce right before you peel or cut it so that any dirt and bacteria aren’t picked up by your knife and transferred back onto the fruit or vegetable or elsewhere in your kitchen.

The Mediterranean Diet: Brain Booster

One of the reasons I’m such a proponent of olive oil is the key role it plays in the fabulously healthy Mediterranean diet, known for its heart health benefits. A recent study published in the journal Neurology advances the theory that it protects brain health too. The researchers found that, among a group of 500 seniors, those who ate an unhealthy diet had higher levels of amyloid and tau proteins, which have been linked to Alzheimer’s, in their cerebrospinal fluid, and that they performed worse in memory tests than those who regularly ate a Mediterranean-like diet. “There was also a significant positive correlation between a closer adherence to a Mediterranean-like diet and a higher volume of the hippocampus. The hippocampus is an area of the brain that is considered the control center of memory. It shrinks early and severely in Alzheimer’s disease,” explained Tommaso Ballarini, PhD, lead author of the study. “It is possible that the Mediterranean diet protects the brain from protein deposits and brain atrophy that can cause memory loss and dementia.” The researchers will continue their work by reexamining the same study participants in four to five years.

In the meantime, this delicious way of eating isn’t complicated. According to the Mayo Clinic, while there is no single definition of the Mediterranean diet, it is typically high in vegetables, fruits, whole grains, beans, nuts and seeds, and olive oil. Here’s an easy way to adopt it:

  • Daily: vegetables, fruits, whole grains, and healthy fats
  • Weekly: fish, poultry, beans and eggs with moderate portions of dairy
  • Limited: red meat

The Link Between Exercise and Sleep

There are many factors that contribute to good health, with getting enough exercise and getting good quality sleep among them. We know that, separately, physical inactivity and poor sleep are linked to a greater risk of death from causes such as heart disease and cancer. New research published in the British Journal of Sports Medicine now shows that exercise and sleep may be more linked to each other than we thought. Scientists looked at the exercise and sleep patterns of more than 380,000 middle-aged adults over an 11-year period and how different combinations affected their health. Not surprisingly, compared with those with a high physical activity level and healthy sleep combination, those at the other extreme—no moderate-to-vigorous physical activity and poor sleep—were most at risk for heart disease, stroke, and cancer. However, the findings also showed that getting the recommended 150 minutes of exercise a week could mitigate the risks posed by poor sleep, prompting the researchers to suggest that there’s a certain synergy between the two activities. This was an observational study that relied on self-reported data so cause and effect can’t be established, but it does give the idea that you should meet physical activity goals as you work on getting better sleep. Other lifestyle habits that helped participants achieve better sleep levels were being thinner, eating more fruits and vegetables, spending less time sitting each day, not smoking, and limiting alcohol.

Does eating a Mediterranean diet protect against memory loss and dementia?

Posted on by The Olive Oil Hunter

Adapted from an article from the American Academy of Neurology, May 6, 2021

Eating a Mediterranean diet that is rich in fish, vegetables, and olive oil may protect your brain from protein buildup and shrinkage that can lead to Alzheimer’s disease, according to a new study. The research is published in the May 5, 2021, online issue of Neurology.

The study looked at abnormal proteins called amyloid and tau. Amyloid is a protein that forms into plaques, while tau is a protein that forms into tangles. Both are found in the brains of people with Alzheimer’s disease but may also be found in the brains of older people with normal cognition.

The Mediterranean diet includes high intake of vegetables, legumes, fruits, cereals, fish, and monounsaturated fatty acids such as olive oil, and low intake of saturated fatty acids, dairy products, and meat.

“Our study suggests that eating a diet that’s high in unsaturated fats, fish, fruits and vegetables, and low in dairy and red meat may actually protect your brain from the protein buildup that can lead to memory loss and dementia,” said study author Tommaso Ballarini, PhD, of the German Center for Neurodegenerative Diseases (DZNE) in Bonn, Germany. “These results add to the body of evidence that show what you eat may influence your memory skills later on.”

The study involved 512 people. Of those, 169 were cognitively normal, while 343 were identified as being at higher risk of developing Alzheimer’s disease. Researchers looked at how closely people followed the Mediterranean diet based on their answers to a questionnaire asking how much they ate of 148 items over the previous month. People who often ate healthy foods typical of the Mediterranean diet, like fish, vegetables, and fruit, and only occasionally ate foods not typical of the Mediterranean diet like red meat, received the highest scores, for a maximum score of nine.

Cognitive skills were assessed with an extensive test set for Alzheimer’s disease progression that looked at five different functions, including language, memory, and executive function. All the participants had brain scans to determine their brain volume. In addition, the spinal fluid of 226 study participants was tested for amyloid and tau protein biomarkers.

Researchers then looked at how closely someone followed the Mediterranean diet, and the relationship to their brain volume, tau and amyloid biomarkers, and cognitive skills. After adjusting for factors like age, sex, and education, researchers found that in the area of the brain most closely associated with Alzheimer’s disease, each point lower people scored on the Mediterranean diet scale equated to almost one year of brain aging.

When looking at amyloid and tau in people’s spinal fluid, those who did not follow the diet closely had higher levels of biomarkers of amyloid and tau pathology than those who did. When it came to a test of memory, people who did not follow the diet closely scored worse than those who did.

“More research is needed to show the mechanism by which a Mediterranean diet protects the brain from protein buildup and loss of brain function, but findings suggest that people may reduce their risk for developing Alzheimer’s by incorporating more elements of the Mediterranean diet into their daily diets,” Ballarini said.

Lamb Loin Chops with Lemon-Mint Gremolata, Spotlight on Gremolata, Why Proteins Need to Rest, Secrets of the World’s Healthiest Country, and Exercise for Your Brain

Lamb is finally having its moment in American cuisine. Many of us didn’t grow up eating lamb, so if you’ve never tried it, you may just think you don’t like it. Or if you’ve only known it as a special occasion or holiday dish, it might not occur to you to shop for it on a regular basis. But lamb has a mild, tender taste that meat eaters will love, and loin or shoulder chops are perfect for the grill any day of the year. Salt, pepper, and a quick rub with extra virgin olive oil, and you’re set to go.

Lamb Loin Chops with Lemon-Mint Gremolata

  • The Olive Oil Hunter News #38 Lamb Loin Chops with Lemon-Mint Gremolata

    Lamb is finally having its moment in American cuisine. Many of us didn’t grow up eating lamb, so if you’ve never tried it, you may just think you don’t like it. Or if you’ve only known it as a special occasion or holiday dish, it might not occur to you to shop for it on a regular basis. But lamb has a mild, tender taste that meat eaters will love, and loin or shoulder chops are perfect for the grill any day of the year. Salt, pepper, and a quick rub with extra virgin olive oil, and you’re set to go.

    Ingredients

    • 2 garlic cloves, peeled and roughly chopped
    • 1/4 cup fresh mint leaves
    • 1/4 cup fresh flat-leaf parsley leaves
    • Zest of 1 lemon
    • 2 tablespoons fresh lemon juice
    • 1/4 cup shelled hazelnuts
    • 1/4 cup extra virgin olive oil, plus extra for brushing on the lamb chops
    • Kosher salt to taste
    • Coarsely ground black pepper to taste
    • 8 lamb loin chops

    Directions

    Step 1

    Make the gremolata: In a blender or mini food processor, combine the garlic, mint, parsley, lemon zest and juice, and hazelnuts. Pulse several times, and then slowly add the 1/4 cup of olive oil. Process until relatively smooth. If the mixture seems stiff, add a small amount of water. Season with salt and pepper. Reserve.

    Step 2

    Preheat your grill to medium-high. Brush the lamb chops on both sides with olive oil, and season well with salt and pepper. Grill for 2 to 3 minutes per side for medium-rare. After letting chops rest for 5 minutes, plate two chops per person with a healthy dollop of the gremolata and pass the rest.

    Yields 4 servings.

The Greatness of Gremolata

If you’re a sauce maven like me, you need gremolata in your repertoire. Traditionally used as a garnish for osso buco, the slow-braised veal shank dish from the Lombardy region, this classic Italian mixture is a masterful garnish for all types of foods, from grilled meat, chicken, and fish to roasted vegetables and creamy soups. Always use the freshest parsley, mint, and garlic, and make it as close to mealtime as possible for the best flavor.

Healthy Kitchen Tip: Why Proteins Need to Rest

Healthy Kitchen Nugget

Why Proteins Need to Rest

I always say it about grilled meats, but the same goes for roasts: Proteins need to rest and redistribute their juices before you cut into them. Otherwise, those juices will pour out—and will often be lost—as you make your first slice. Of course, this is more essential, and the rest time is longer, for a large flank steak than for individual lamb chops. Keep in mind that during this time out of the oven or off the grill, the food continues to cook, and its internal temperature will rise anywhere from a few degrees in a small portion of meat to 10 or 15 degrees in a turkey. Consider these additional degrees when testing food with your instant-read thermometer, and take it off the heat source accordingly, to avoid going beyond the level of doneness you desire.

Secrets of the World’s Healthiest Country

Members of the Fresh-Pressed Olive Oil Club know that I’ve been working with artisanal olive growers in Spain for my extra virgin olive oil since 2005. Olive oil courses through daily life in Spanish towns—when people hear you are interested in olive oil, they brighten, invariably promising to put you in touch with their cousin or neighbor who grows olives. Olive oil is such an integral part of the Mediterranean diet of healthy fats, legumes, fruits, and vegetables, which Spaniards elevate to great heights with their fabulous cuisine. So it was no surprise to me when Spain ranked #1 in the last Bloomberg Global Health Index report.

The index uses a group of factors to rank the countries of the world on a scale from 0 to 100, with 100 being the ideal. The factors are life expectancy, malnutrition, causes of death, the availability of clean water, and health risks like tobacco use, high blood pressure, and obesity. With a score of 92.75, Spain took top honors. It boasts a life expectancy projected to rise to 85.8 years by 2040—the highest in the world. In addition to its signature healthy diet, Spain is also a country of walkers, which is so great for fitness. And guess what country came in second? Its close neighbor on the other side of the Mediterranean: Italy!

Exercise: Good for the Mind

A recent report in ACSM’s Health & Fitness Journal crystallized what health experts have been saying for years: Beyond its benefits for physical health, exercise is great for mental health, with both short- and long-term advantages. Across your life span, the more you engage in physical activity, the more you can reduce the risk of depression and anxiety, two crippling mental illnesses. And should you develop one of these issues, the cumulative effects of regular exercise can help you cope better.

Just having a bad day? An exercise session can get you out of a blue mood and defuse anger, stress, and tension. Get in a brisk walk at lunch, and you may find that you have better concentration and renewed enthusiasm in the afternoon.

Scientists don’t have a magic formula for the type, intensity, or length of a mental health-boosting workout, but that’s not really a problem. Sticking with a workout plan is what’s most important, and the secret to doing that is to go with your individual preferences—there’s no point in forcing yourself to run for five miles if what you really like to do is play tennis. Know that mind-body exercises like yoga, tai chi, and qigong can improve symptoms of depression and anxiety as well as other forms of exercise do, and put together a menu of choices that appeal to you. Even though fitness guidelines for heart health look at weekly totals—150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic exercise per week (plus resistance and flexibility exercises), the more you can spread out those minutes, the better: 10 to 20 minutes each and (almost) every day is most helpful to regulate mood.
