    Grilled meat with herbaceous chimichurri sauce is a South American staple, popular in Argentina, Brazil, and Chile. Substitute flank steak or hanger steak if you can’t find skirt steak.

    Ingredients

    For the chimichurri:

    • 1 cup fresh flat-leaf parsley, stemmed
    • 1/2 cup fresh cilantro
    • 3 to 4 cloves garlic, coarsely chopped
    • 1 tablespoon fresh or teaspoon dried oregano
    • 1 fresh jalapeño, stemmed and seeded, or 1 teaspoon red pepper flakes
    • 1/2 cup extra virgin olive oil
    • 3 to 4 tablespoons red wine vinegar
    • 3 to 4 tablespoons water
    • Kosher salt to taste
    • Freshly ground black pepper to taste

    For the Steak:

    • 2 pounds trimmed skirt steak
    • More kosher salt and freshly ground black pepper to taste

    Directions

    Make the chimichurri:

    Place the parsley, cilantro, garlic, oregano, and the jalapeño or red pepper flakes in a food processor and finely chop, running the machine in short bursts. With the motor running, add the olive oil in a thin stream, followed by 3 tablespoons of the vinegar and 3 tablespoons of water. Taste the chimichurri, adding another tablespoon of vinegar to make it tarter, if desired. If necessary, add another tablespoon of water to thin the chimichurri to a pourable consistency. Season with salt and pepper to taste; it should be highly seasoned. Set aside for up to 2 hours.

    Preheat your grill to medium-high. Season the skirt steak on both sides with salt and pepper. Grill for 3 to 5 minutes per side, depending on its thickness (medium-rare is best). Let it rest for 2 to 3 minutes, then thinly slice the meat on a diagonal. Arrange on a platter and serve with the chimichurri sauce.

    Yields 4 to 6 servings

Healthy Ingredient Spotlight: Red Pepper Flakes

Healthy Ingredient Spotlight

Red Pepper Flakes

Crushed red pepper flakes are a great, quick way to add a little heat to any dish, and there’s probably a generic jar of it on your spice shelf. It’s typically made from cayenne peppers and includes some seeds for extra zing, but it’s just as easy to make your own using whatever type of dried peppers you like best. Pulse one or two stemmed peppers with their seeds in a coffee bean grinder—be careful not to pulverize them—and then transfer them to a spice jar with large holes in the sifter fitment (that’s the technical name of the plastic piece that snaps over the jar).

Have fresh peppers from your garden? Dry them in your oven or dehydrator or tie them up and allow them to air-dry upside down, and then grind them. Just as you do when chopping peppers, wear gloves when transferring peppers from grinder to jar to keep the capsaicin from getting on your fingertips, which could burn your eyes if you touch them.

Healthy Kitchen Tip: Grilling with Flavored Wood Chips

Healthy Kitchen Nugget

Customize Grilling Flavor with Wood Chips ​

Chips made from fruit tree woods, like apple, peach, and pear, as well as alder, provide a mild flavor, great for chicken and seafood. Hickory, oak, pecan, and maple give meat a bolder flavor, and mesquite adds the strongest flavor of all. Experiment with various wood chips, but unless you’re getting the wood straight from your own tree, buy packets of chips designed for a grill or smoker.

If you use a gas grill, you can still get wonderful smoky flavor: Use a smoker box loaded with wood chips or simply make a DIY aluminum foil pouch filled with chips. Place the smoker box as directed in your grill instructions (some suggest putting it on the grill grate, others below it). Once the chips begin smoking, move the box/pouch to the cooler side of the grill before cooking your food.

For Your Best Health: Olive Oil and Brain Function

Olive Oil Helps Counter Cognitive Impairment

A study published late last year in the Journal of Alzheimer’s Disease highlighted the potential of extra virgin olive oil to improve brain function in older adults with a condition called amnestic Mild Cognitive Impairment, or aMCI, characterized by memory loss and the inability to do very complex activities of daily living, and considered an early warning sign of Alzheimer’s. For the first-of-its-kind research, scientists from the Aristotle University of Thessaloniki and the Greek Association of Alzheimer’s Disease and Related Disorders compared the effects of high-phenolic early-harvest extra virgin olive oil (HP-EH-EVOO) to moderate phenolic, or MP-EVOO, and to the Mediterranean diet (MeDi) to see how well the HP-EH-EVOO worked as a therapeutic compound (there is currently no treatment for aMCI). Called the MICOIL study, it built on prior research that found EVOO can protect cognitive function.

Study participants were divided among three groups: Group 1 received 50 mL (about 3 tablespoons) of HP-EH-EVOO every day, Group 2 received the same amount of MP-EVOO, and Group 3 was simply told to follow a Mediterranean diet. Also, they were tested for a genetic predisposition to APOEɛ4, a protein linked to the development of Alzheimer’s. After 12 months, Group 1 had better follow-up performance compared to Group 2 and Group 3 in almost all cognitive domains. Group 2 had significant improvement compared to Group 3 in two important cognitive tests. What’s more, there was a significant difference in the level of APOEɛ4 in Group 1 and Group 2 versus Group 3.

The scientists concluded that long-term HP-EH-EVOO or MP-EVOO was associated with significant improvement in cognitive function compared to the Mediterranean diet alone. This isn’t to say that the diet isn’t helpful—dozens of studies have shown it supports many areas of health, including the heart. But, as the researchers point out, it’s not a single prescribed diet, but rather a general food-based eating pattern that varies by local and cultural differences throughout the Mediterranean region. Having 50 m/L of high-phenol EVOO olive oil daily could help further its known benefits.

Getting Dirty Is Healthy ​

We’re learning more and more about the benefits of outdoor training. As certified health coach and entrepreneur Preston Blackburn wrote in The Power of Dirt: The Benefits of Outdoor Exercise for the American Council on Exercise, “a good old-fashioned messy, muddy, dirty workout can bring benefits beyond the obvious physical ones by improving cognition and reducing stress, anxiety, and depression.”

Getting sweaty and dirty through sports is fun, as any kid who’s played on a field in the rain and rolled around in the mud knows. As adults, Blackburn wrote, these opportunities are few and far between, and we tend to shy away from them even if they do come along, but that’s a mistake. Benefits of the great outdoors start with the gut microbiome-enhancing, immune-system boosting power of actual dirt and extend to the regions of the brain involved in mood and mental acuity. Add in the known vitamin D boost of being outdoors and the calming effects of green spaces, and you have more than enough reasons to get out your old soccer ball and organize a pickup game with friends in the nearest park.

Roasted Shrimp With Corn and Burst Tomatoes

Posted on by The Olive Oil Hunter

This is a fun dish in the South American style of using round chunks of sweet corn on the cob. If you’d prefer, slice the kernels off the raw ears after husking and add them to the baking dish when you add the shrimp. For a variation, toss the finished dish with cooked pasta.

Ingredients

  • 1/4 cup dry white wine
  • 3 tablespoons fresh lemon juice
  • 3 cloves garlic, minced
  • 1 teaspoon kosher salt, plus more to taste
  • 1 teaspoon hot red pepper flakes or more to taste
  • 1/2 cup plus 2 tablespoons extra virgin olive oil
  • 1 pound large shrimp, peeled and deveined
  • 1 pint red cherry tomatoes
  • 2 ears sweet corn, husked, cut crosswise into 1-inch wheels
  • Freshly ground black pepper to taste
  • 2 tablespoons chopped fresh cilantro or parsley
  • Crusty bread for serving

Directions

Step 1

Preheat your oven to 350°F. In a large bowl, combine the white wine, lemon juice, garlic, teaspoon of salt, and pepper flakes. Whisk in the 1/2 cup of olive oil. Pat the shrimp dry with paper towels, add them to the marinade, and toss to coat.

Step 2

Place the tomatoes and corn in a large glass or ceramic baking dish and drizzle with the remaining 2 tablespoons of olive oil. Season to taste with salt and black pepper. Roast for 20 minutes or until the tomatoes begin to split.

Step 3

Tip the bowl of shrimp with its marinade over the tomatoes and corn and stir to combine, spreading out the shrimp in a single layer.

Step 4

Roast for an additional 15 minutes, or until the shrimp are opaque and cooked through. Stir in the cilantro or parsley. Serve with crusty bread to mop up the juices.

Healthy Ingredient Spotlight: Shrimp Safety ​

Healthy Ingredient Spotlight

Shrimp Safety ​

Shrimp is not immune to the wild vs. farm-raised debate. Often, both the harvesting/farming practices and the country of origin need to be taken into consideration. According to industry watchdog group Monterey Bay Aquarium Seafood Watch, giant tiger prawns farmed worldwide in indoor recirculating tanks with wastewater treatment are a “Best Choice.” This is a sophisticated farming method that minimizes the release of chemicals into the environment and the chances of disease outbreaks. You might see these shrimp sold as freshwater prawns, freshwater shrimp, and giant river shrimp. Whiteleg shrimp farmed in the U.S. are another farmed Best Choice.

In terms of wild, northern shrimp caught with traps in Nova Scotia, Canada, are a Best Choice, with very few concerns about habitat or ecosystem impacts. You might see these shrimp sold as great northern shrimp, Pacific pink shrimp, pink shrimp, and salad shrimp.

Most wild-caught shrimp from the U.S. are considered a Seafood Watch “Good Alternative,” but avoid ridgeback prawns from California and shrimp caught with skimmer trawls anywhere in the Gulf of Mexico with the exception of Florida.

Seafood Watch-assessed sources of shrimp and prawns from Argentina, China, Guyana, India, Indonesia, Malaysia, Nicaragua, and Vietnam are on its “Avoid” list due to concerns over catching and/or farming practices.

When possible, buy shrimp that’s been eco-certified by the Marine Stewardship Council (MSC), the Aquaculture Stewardship Council (ASC), or Best Aquaculture Practices (BAP). You can easily check to see whether a particular species or source is safe on the Seafood Watch website.

Healthy Kitchen Tip: Quick-Cooked Fresh Corn ​

Healthy Kitchen Nugget

Quick-Cooked Corn ​

Got an abundance of corn on the cob? Here’s a fast and foolproof way to cook it: Fill a stockpot three-quarters of the way with water, add a tablespoon of salt, and bring to a rapid boil. Add your shucked corn, cover the pot tightly with a lid, and take the pot off the heat. After seven minutes, the corn will be ready to serve.

Buying tip: Choose corn with the husk still on since it protects the kernels. Husks should be a bright green color and should hug the cob. Peel back just the tip of the husk to be sure that the silk is still moist and the kernels are bright yellow and/or white, depending on the variety.

For Your Best Health: Fermented Food Is Fab ​

For Your Best Health

Why Fermented Food Is Fab ​

There’s no doubt that fiber is good for health, but new research that compared the effects of fiber to those of fermented foods found that fermented foods can have unique—and rapid—benefits for the all-important gut microbiome and the immune system. Consuming foods and drinks such as yogurt, kefir, fermented cottage cheese, kimchi and other fermented vegetables, vinegar, vegetable brine drinks, and kombucha tea led to greater microbial diversity, with stronger effects from larger servings. “This is a stunning finding,” said Justin Sonnenburg, PhD, an associate professor of microbiology and immunology at the Stanford University School of Medicine. “It provides one of the first examples of how a simple change in diet can reproducibly remodel the microbiota across a cohort of healthy adults.”

For 10 weeks, the study participants followed either a high-fiber diet rich in legumes, seeds, whole grains, nuts, vegetables, and fruits, or a diet high in fermented foods. During the follow-up, four types of immune cells showed less activation in the fermented-food group. Also, levels of 19 inflammatory proteins measured in blood samples decreased, something not seen in those on the high-fiber diet. One of these proteins, interleukin-6, has been linked to conditions including rheumatoid arthritis, type 2 diabetes, and chronic stress.

“We expected high fiber to have a more universally beneficial effect and increase microbiota diversity,” said Erica Sonnenburg, PhD, a senior research scientist in basic life sciences, microbiology, and immunology at Stanford. “The data suggest that increased fiber intake alone over a short time period is insufficient to increase microbiota diversity…It is possible that a longer intervention would have allowed for the microbiota to adequately adapt to the increase in fiber consumption.”

So, this isn’t an either-or finding—rather, it suggests that we enjoy both types of foods. High-fiber diets are linked to lower rates of mortality, while eating fermented foods can help with weight maintenance and may decrease the risk for diabetes, cancer, and heart disease. In fact, the researchers will soon test whether high-fiber and fermented foods can work together to boost the microbiome and immune system.

Protecting Against Wildfire Smoke ​

You don’t have to live on the West Coast for your lungs to be affected by the fallout from this season’s wildfires as the smoke travels across the country. As much attention as these horrific fires have received, few people take enough precautions to avoid the toxic smoke and particulate matter that can easily find their way into the lungs and bloodstream. Here are some steps suggested by three Stanford experts: Kari Nadeau, MD, PhD, director of Stanford’s Sean N. Parker Center for Allergy & Asthma Research; Mary Prunicki, MD, PhD, the center’s director of air pollution and health research; and Lynn Hildemann, PhD, professor and department chair of civil and environmental engineering.

Before you go outside to exercise or just run errands, know the outside air quality—track it easily with an app or website. When the Air Quality Index is high, stay inside as much as possible. When you must go out, an N95 mask can be effective at keeping out particulate matter.

Know your indoor air quality, too. See if your utility company offers a home energy audit—free in many areas—to assess how well-sealed your home is. The audit should identify energy-saving measures to better secure areas where smoke could get in.

If you have central A/C, run it on smoky days—its filter is designed to trap dust and small particles, so it offers some protection. Change all air filters in your home regularly. Be sure to use true HEPA filters—those with a high-efficiency particulate air designation—designed to remove 99.97% of airborne particles. It should state this on the box. Skip packages labeled “HEPA-like” or “approaching HEPA” quality. If possible, invest in a high-quality air purifier for your home. If you can’t purify your entire home, pick one room to focus on and maintain healthy air quality there.
