Heart health: Mediterranean versus low-fat diet

Adapted from an article by Timothy Huzar in Medical News Today, December 15, 2020

In a recent study, scientists compared the effects of a Mediterranean diet with those of a low-fat diet on key biological processes linked to heart health.

The researchers found that a Mediterranean diet could improve endothelial function in people with coronary heart disease. The endothelium is a thin membrane that coats the inside of blood vessels and the heart. It plays a number of roles that are important for the functioning of the cardiovascular system.

Heart disease

As the Centers for Disease Control and Prevention (CDC) report, heart disease accounts for around 1 in 4 deaths in the United States, making it the leading cause of death. Modifying the diet is a keyway to reduce the risk of heart disease. For many years, researchers have demonstrated the benefits of a Mediterranean diet on heart health. It includes olive oil, vegetables, nuts, legumes, fruits, and whole grains, with small amounts of dairy and meat and a moderate amount of fish and red wine. Health experts, including the American Heart Association (AHA), have also linked low-fat diets with improvements in heart health. This type of diet contains reduced amounts of all types of fat and increased amounts of complex carbohydrates.

The team behind the present study set out to test the effects of each type of diet on the endothelium because endothelial dysfunction is a predictor of cardiovascular disease. According to Prof. José López-Miranda, the corresponding author of the study and coordinator of the Nutritional Genomics and Metabolic Syndrome research group at the Maimonides Biomedical Research Institute of Córdoba, in Spain:

The degree of endothelial damage predicts the occurrence of future cardiovascular events, as in acute myocardial infarctions. If we can take action at the initial stages, prompting endothelium regeneration and better endothelial function, we can help prevent heart attacks and heart disease from reoccurring.

The researchers analyzed data gathered as part of the Coronary Diet Intervention with Olive Oil and Cardiovascular Prevention study, an ongoing, single-blind, randomized, controlled study. The study included 1,002 people with coronary heart disease who had not had a coronary event in the past 6 months. The researchers determined a baseline level of endothelial dysfunction among the participants. They then assigned the participants to two groups: one followed a Mediterranean diet for 1 year, and the other followed a low-fat diet for 1 year.

At the end of the year, the team measured the participants’ endothelial function again. In total, 805 participants completed the study.

Compared with the low-fat diet, the Mediterranean diet significantly improved the participants’ endothelial function—no matter how severe the dysfunction had been.

The researchers also found that the Mediterranean diet resulted in improved levels of high-density lipoprotein cholesterol and reductions in fasting glucose and C-reactive protein (a marker of inflammation) among the participants, compared with the low-fat diet.

The findings suggest that switching to a Mediterranean diet could help reduce the known risk of endothelial damage, coronary heart disease, and future coronary events.

One-Pot Pasta with Sausage and Spinach

Hearty, filling, and needing only one pot, this comforting dish will warm a three-dog night. I first cooked with passata (strained uncooked tomato purée) during a visit to Italy, but have since found passata on some upscale American supermarket shelves.

Ingredients

  • 2 tablespoons extra virgin olive oil, plus extra for serving
  • 2 sweet or hot Italian sausages (5 to 6 ounces each), casings removed
  • One 24-ounce jar of passata (see above) or one 28-ounce can crushed tomatoes
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon hot red pepper flakes
  • Kosher salt
  • 1 pound cavatappi, fusilli, or other small, tubular pasta
  • 5 packed cups baby spinach (about 5 ounces)
  • 1/2 cup grated Parmesan

Directions

Step 1

Heat the 2 tablespoons of olive oil in a 12-inch, deep skillet with a tight-fitting lid or a Dutch oven over medium-high heat until shimmering. Use your hands to pull the sausages apart into small pieces; add to the skillet and cook untouched for 1 minute.

Step 2

Continue to cook for another 4 to 6 minutes, stirring at 1-minute intervals and breaking up the sausage into 1/2-inch chunks, until browned and crispy on the outside with no pink remaining.

Step 3

Carefully pour in the passata (it may splatter), then add the cumin, red pepper flakes and 2 cups of water, stirring to combine. Season with salt and increase the heat to bring to a boil.

Step 4

Add the pasta, coating it with the liquid. (It won’t be fully submerged, and that’s OK.) Adjust the heat to maintain an active simmer with small bubbles forming on the surface. Cover and let cook, stirring every few minutes to make sure nothing is sticking at the bottom of the pan, until the pasta is al dente, about 1 minute less than the package instructions. If the pasta is still hard at this point, add a few tablespoons of warm water at a time and cook until just al dente. Depending on your pasta size and shape, you may need to add several tablespoons of water.

Step 5

When the pasta is just al dente, reduce the heat to low and season to taste with salt. Stir in the spinach in batches, and cook, uncovered, until most of the spinach is wilted, about 1 minute more. (It will continue to wilt in the heat of the pasta after you serve it.) If the pasta seems too dry, add 1 tablespoon warm water at a time until it reaches your desired consistency.

Step 6

Divide the pasta among serving bowls. Top with Parmesan and serve additional extra virgin olive oil on the side for drizzling.

Healthy habits are key to maintaining health even while taking multiple prescriptions

Adapted from an article in Science Codex, November 9, 2020

Lifestyle habits including adherence to the Mediterranean diet, getting regular exercise, and not smoking can reduce the risk of death, even for people taking multiple medications, according to preliminary research presented at the American Heart Association’s Scientific Sessions 2020. The meeting, held virtually, Friday, November 13 – Tuesday, November 17, 2020, was a premier global exchange of the latest scientific advancements, research and evidence-based clinical practice updates in cardiovascular science for health care worldwide.

“We’ve long known about the benefits of leading a healthy lifestyle. The results from our study underscore the importance of each person’s ability to improve their health through lifestyle changes even if they are dealing with multiple health issues and taking multiple prescription medications,” said lead author Neil Kelly, Ph.D., a medical student at Weill Cornell Medicine of Cornell University in New York City.

The study analyzed data from more than 20,000 participants of the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study (average age of 64; 56% women). At the start of the study, 17% were taking 10 or more prescription medications, 39% were taking five to nine prescription medicines, and 44% of participants were taking four or fewer prescription medications.

Researchers evaluated the number of medications taken, level of participation in four healthy behaviors and all-cause death rates. The types of medications and the conditions they were used to treat (e.g., heart disease, diabetes, kidney disease, cognitive impairment, etc.), varied widely among study participants. The healthy lifestyle behaviors were physical activity; smoking abstinence; low sedentary time; and following a Mediterranean diet, which emphasizes legumes, fruits, vegetables, whole grains, fish, and olive oil, and moderation for dairy products and wine.

At follow-up roughly 10 years later, the analysis found that a healthy lifestyle decreased the risk of death regardless of the number of medications a person was taking; and the higher the number of healthy lifestyle habits a person had, the lower their risk of death.

“It’s especially important for health care professionals to counsel patients and develop interventions that can maximize healthy lifestyle behaviors, even among patients with several prescription medications,” Kelly added. “It’s important for the public to understand that there is never a bad time to adopt healthy behaviors. These can range from eating a healthier diet to taking a daily walk in their neighborhood. A healthier lifestyle buys more time.”

Italian Apple Olive Oil Cake

Rustic and moist, this Ligurian cake deserves a place in your olive oil baking repertoire. It will infuse your kitchen with the scents of late fall—apples, cinnamon, and nutmeg. No frosting is required, but we wouldn’t say no to a drizzle of warm honey or a scoop of premium vanilla ice cream.

Ingredients

  • 2 large Gala apples, peeled and finely chopped
  • Orange juice to soak apples in
  • 3 cups all-purpose our
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon freshly ground nutmeg
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1 cup granulated sugar
  • 1 cup extra virgin olive oil
  • 2 large eggs
  • 2/3 cup golden raisins, soaked in warm water or apple cider for 15 minutes
  • Confectioner’s sugar, for dusting

Directions

Step 1

Preheat the oven to 350°F.

Step 2

Place the chopped apples in a bowl and add orange juice—just enough juice to toss and coat apples to prevent browning.

Step 3

In a large mixing bowl sift together the our, cinnamon, nutmeg, baking powder, and baking soda. Set aside.

Step 4

In the bowl of a stand mixer fitted with a whisk, add the sugar and extra virgin olive oil. Mix on low for 2 minutes until well-combined. While the mixer is on, add the eggs, one at a time, and continue to mix another 2 minutes until mixture increases in volume (it should be thicker but still runny).

Step 5

In the large bowl with the dry ingredients, make a well in the middle of the our mixture. Add the wet mixture (the sugar and olive oil mixture) into the well. Using a wooden spoon, stir until just blended; it will be a thick batter (do not add anything to loosen it).

Step 6

Drain the raisins (which have been soaking in warm water) completely; rid the apples of excess juice by blotting them with paper towels. Add both raisins and apples to the batter and mix with spoon until well-combined. Again, batter will be fairly thick.

Step 7

Line a 9-inch round cake pan with parchment paper. Spoon the thick batter into the pan, and level the top with the back of a wooden spoon.

Step 8

Bake for 45 minutes or until a toothpick or wooden skewer inserted in the center comes out clean.

Step 9

Cool completely in the pan. When ready, simply lift parchment up to transfer the cake to a plate or cake stand. Dust with confectioner’s sugar before serving.
