Posted on by The Olive Oil Hunter

One of our favorite restaurants in Chile is Fuegos de Apalta (Fires of Apalta) in the Colchagua Valley. It was opened by celebrity chef Francis Mallmann in 2017. Here is one of his recipes.

Ingredients

  • 2 large ripe red Bartlett pears, halved, cored, and cut into thick wedges
  • Sea salt, to taste
  • 8 ounces blue cheese (such as Saint Agur), brought to room temperature and cut into wedges
  • 12 dates, pitted
  • 1/3 cup extra virgin olive oil, for drizzling
  • 1/4 cup loosely packed fresh mint leaves
  • 1 teaspoon pink peppercorns, toasted and lightly crushed
  • Eight 1/2-inch-thick slices country-style white bread

Directions

Divide the pears among 4 salad plates and season with salt. Arrangea wedge of cheese and 3 dates on each plate. Drizzle with the olive oil and garnish with the mint and peppercorns. Serve with the sliced country bread for dipping in the olive oil.

Chickpea Flatbreads with Burst Tomato Sauce

Posted on by The Olive Oil Hunter

Chilean merquén, one of our favorite seasonings, is made from sun-dried chiles that are smoked and ground, then blended with other ingredients such as toasted cumin and salt. Professional chefs are just beginning to discover it! Find merquén at amazon.com.

Ingredients

  • 1 cup chickpea flour
  • 10 tablespoons extra virgin olive oil, divided use, plus more for serving
  • 1 1/2 teaspoons kosher salt, divided
  • 2 pints cherry tomatoes, halved if large
  • 2 garlic cloves, finely chopped
  • One 15-ounce can chickpeas, drained (see Note), rinsed
  • 1 tablespoon dried oregano
  • 1 teaspoon sherry or red wine vinegar
  • 1/4 teaspoon merquén or smoked paprika (optional)
  • 2 tablespoons cold unsalted butter, cut into pieces
  • 1 cup coarsely grated queso fresco or crumbled feta (about 5 oz.)
  • Baby greens, such as arugula, kale, or spinach
  • Lemon wedges, for serving

Directions

Step 1

Place a rack in the top third of the oven; preheat to 450°F. Whisk the chickpea flour, 2 tablespoons of olive oil, 1 teaspoon of salt, and 1 cup water in a medium bowl or large measuring cup until combined. Let sit at least 10 minutes and up to 1 hour to let the flour hydrate.

Step 2

Heat 2 tablespoons olive oil in a 12-inch cast-iron skillet over medium-high heat until shimmering. Pour in exactly half (3/4 cup) of the chickpea batter and tilt to evenly coat the skillet. Transfer to the oven and bake the flatbread until the edges are golden brown, 8 to 10 minutes. Using a large spatula, transfer the flatbread to a wire rack. Repeat with the remaining batter.

Step 3

Meanwhile, cook the tomatoes, garlic, 1/4 cup of olive oil, and the remaining 1/2 teaspoon salt in a large skillet over medium-high heat, stirring occasionally, until the whole tomatoes begin to burst, 4 to 5 minutes. Stir in the chickpeas, oregano, vinegar, and merquén (if using). Reduce the heat to medium and continue to cook, stirring often, until the tomatoes have formed a fully chunky sauce, 3 to 4 minutes. Remove from the heat and stir in the butter.

Step 4

Slice the flatbreads in half. Serve with the tomato-chickpea mixture, cheese, greens, and lemon wedges alongside for squeezing and olive oil for drizzling.

Note: The liquid from drained chickpeas is called aquafaba, and is used by many vegans and vegetarians to lighten baked goods or make egg-free meringues.

Diet including olive oil may reduce blood-clotting risk in healthy obese adults

Posted on by The Olive Oil Hunter

Adapted from an article by the American Heart Association, March, 7, 2019

In a group of healthy obese adults, eating olive oil at least once a week was associated with less platelet activity in the blood, which may reduce the tendency of blood to clot and block blood flow. These findings are according to preliminary research presented at the American Heart Association’s Epidemiology and Prevention/Lifestyle and Cardiometabolic Health Scientific Sessions 2019, a premier global exchange of the latest advances in population-based cardiovascular science for researchers and clinicians.

Platelets are blood cell fragments that stick together and form clumps and clots when they are activated. They contribute to the buildup of artery-clogging plaque, known as atherosclerosis, the condition that underlies most heart attacks and strokes, according to lead study author Sean P. Heffron, MD, MS, MSc, assistant professor at NYU School of Medicine and the NYU Center for the Prevention of Cardiovascular Disease in New York, New York.

Using food frequency surveys, researchers determined how often 63 obese, nonsmoking, nondiabetic study participants ate olive oil. The participants’ average age was 32.2 years and their average body mass index (BMI) was 44.1. Obesity is defined as having a body mass index (BMI)—a ratio of body weight to height—over 30.

Researchers found that those who ate olive oil at least once a week had lower platelet activation than participants who ate olive oil less often, and that the lowest levels of platelet aggregation were observed among those who ate olive oil more frequently.

“People who are obese are at increased risk of having a heart attack, stroke, or other cardiovascular event, even if they don’t have diabetes or other obesity-associated conditions. Our study suggests that choosing to eat olive oil may have the potential to help modify that risk, potentially lowering an obese person’s threat of having a heart attack or stroke,” Heffron said. “To our knowledge, this is the first study to assess the effects of dietary composition, olive oil specifically, on platelet function in obese patients,” said co-author Ruina Zhang, BS, an NYU medical student.

Some limitations of the study are that it relied on questionnaires completed by the participants; it measured how often they ate olive oil, but not how much olive oil they ate; and because it was observational, the study could not prove that eating olive oil will reduce platelet activation in obese adults.

Researchers Explore What’s Behind Mediterranean Diet and Lower Cardiovascular Risk

Posted on by The Olive Oil Hunter

Brigham and Women’s Hospital, December 7, 2018 

A new study by investigators from Brigham and Women’s Hospital, Harvard Medical School, and the Harvard T.H. Chan School of Public Health offers insights from a cohort study of women in the US who reported consuming a Mediterranean-type diet.

Researchers found a 25 percent reduction in the risk of cardiovascular disease among study participants who consumed a diet rich in plants and olive oil and low in meats and sweets. The team also explored why and how a Mediterranean diet might mitigate risk of heart disease and stroke by examining a panel of 40 biomarkers, representing new and established biological contributors to heart disease. The team’s results are published in JAMA Network Open.

“Our study has a strong public health message that modest changes in known cardiovascular disease risk factors, particularly those relating to inflammation, glucose metabolism, and insulin resistance, contribute to the long-term benefit of a Mediterranean diet on cardiovascular disease risk,” said lead author Shafqat Ahmad, PhD, a research fellow at the Brigham and at the Harvard Chan School.

The current research draws on data from more than 25,000 female health professionals who participated in the Women’s Health Study. Participants completed food intake questionnaires about diet, provided blood samples for measuring the biomarkers, and were followed for up to 12 years. The primary outcomes analyzed in the study were incidences of cardiovascular disease, defined as first events of heart attack, stroke, coronary arterial revascularization, and cardiovascular death.

The team categorized study participants as having a low, middle, or upper Mediterranean diet intake. They found that 428 (4.2 percent) of the women in the low group experienced a cardiovascular event, compared to 356 (3.8 percent) in the middle group, and 246 (3.8 percent) in the upper group, representing a relative risk reduction of 23 percent and 28 percent, respectively, a benefit that is similar in magnitude to statins or other preventive medications.

The team saw changes in signals of inflammation (accounting for 29 percent of the cardiovascular disease risk reduction), glucose metabolism and insulin resistance (27.9 percent), and body mass index (27.3 percent).

“While prior studies have shown benefit for the Mediterranean diet on reducing cardiovascular events and improving cardiovascular risk factors, it has been a ‘black box,’ regarding the extent to which improvements in known and novel risk factors contribute to these effects,” said corresponding author Samia Mora, MD, MHS, a cardiovascular medicine specialist at the Brigham and Harvard Medical School. “In this large study, we found that modest differences in biomarkers contributed in a multifactorial way to this cardiovascular benefit that was seen over the long term.”
