Garlicky Kale and Ricotta Crostini Recipe, How the Mediterranean Diet Got Its Name, The Cultural Benefits of Olive Oil and The Key to Sustainable Eating

When we read about the benefits of olive oil, they’re usually centered on its amazing health boosts to the heart, brain, and more. Surprising as it may seem at first glance, there are also cultural benefits from having olive oil as the cornerstone of the Mediterranean diet. These benefits stem from traditions surrounding the growing and pressing of olives, choosing other seasonal and local foods, and preparing and enjoying meals with family and friends. I experience that conviviality firsthand every time I’m at an olive harvest, and it’s exhilarating! What’s more, because olive oil and most components of the diet are plant based, it’s a very sustainable way of eating for our planet. I’m sharing insights from three reports on the importance of olive oil and the Mediterranean diet to inspire you to not only embrace healthy eating, but also to better our environment.

How the Mediterranean Diet Got Its Name

The history of the Mediterranean diet is itself fascinating. According to the article “Impact of Mediterranean Diet on Chronic Non-Communicable Diseases and Longevity,” published in Nutrients in June 2021, the diet was formally described in the Seven Countries Study from the 1950s. The study identified the diet’s health benefits: “Southern European populations from countries where olive trees grow naturally exhibited longevity among the highest in the world, with the lowest incidence of coronary heart disease, cancer, and other non-communicable diseases. These populations did not follow a specific dietary pattern, but some traditional eating and lifestyle habits [that] originated centuries before.” That description piqued the interest of everyone—from scholars to foodies—from that day forward. It’s not hard to argue that the Mediterranean way of life became the inspiration for each of today’s wildly popular plant-based diets.

That early research showed that over 60% of the calories in the Mediterranean diet came from plant foods, compared to just 37% in the American diet, and though both populations ate the same number of fat calories, the main source of these calories among Mediterranean people was olive oil, not the animal fat preferred in the US. The researchers of the study were surprised by how healthy the Mediterranean people were despite living without the so-called advances of the Western industrialized world! People in the region might have wished for more meat in their diet, but it was precisely the lack of meat and the emphasis on plant-based foods, including the physical activity of cultivating, gathering, and cooking them, that kept certain diseases at bay.

Cultural Benefits of Olive Oil

The Cultural Benefits of Olive Oil

As more studies were done, it also became clear that the Mediterranean diet wasn’t only about food, but also about traditions and practices that were passed down through generations, “extending from the countryside and food production to the ways of cooking, which provide a feeling of belonging and permanency to the community. Mediterranean traditional cuisines are rich in aromas, colors, and memories, highlighting the taste and the synchronization with nature, and emphasizing the significance of preparing and consuming foods jointly with family and friends,” states the article in Nutrients

The way of life connected to the Mediterranean diet is so unique that in 2010 UNESCO, known for designating geographical areas as world heritage sites, gave the diet its cultural registration of “Intangible Cultural Heritage of Humanity,” first singling out Greece, Italy, Morocco, and Spain and then adding Croatia, Cyprus, and Portugal in 2013.

Here’s how UNESCO describes it:

The Mediterranean diet involves a set of skills, knowledge, rituals, symbols and traditions concerning crops, harvesting, fishing, animal husbandry, conservation, processing, cooking, and particularly the sharing and consumption of food. Eating together is the foundation of the cultural identity and continuity of communities throughout the Mediterranean basin. It is a moment of social exchange and communication, an affirmation and renewal of family, group or community identity. The Mediterranean diet emphasizes values of hospitality, neighbourliness, intercultural dialogue and creativity, and a way of life guided by respect for diversity. It plays a vital role in cultural spaces, festivals and celebrations, bringing together people of all ages, conditions and social classes. It includes the craftsmanship and production of traditional receptacles for the transport, preservation and consumption of food, including ceramic plates and glasses. Women play an important role in transmitting knowledge of the Mediterranean diet: they safeguard its techniques, respect seasonal rhythms and festive events, and transmit the values of the element to new generations. Markets also play a key role as spaces for cultivating and transmitting the Mediterranean diet during the daily practice of exchange, agreement and mutual respect.

With so much focus on its social and cultural aspects, it’s no wonder that a group of researchers reimagined the food pyramid. In their version, olive oil, fruits and vegetables, and grains are the food foundation, but the base level of the pyramid illustrates the activities and traditions highlighted by UNESCO.

Sustainable Eating

The Key to Sustainable Eating

In the paper “Looking for Commensality: On Culture, Health, Heritage, and the Mediterranean Diet,” published in March 2021 in the International Journal of Environmental Research and Public Health, the Mediterranean diet gets the nod as a way to feed the planet in a sustainable way. The paper refers to the report from the EAT-Lancet Commission on healthy diets from sustainable food systems “that highlighted the evidence that a diet rich in plant-based foods and fewer foods of animal origin confers not only optimal health outcomes but also environmental benefits. The Commission presented an integrated framework providing scientific targets for healthy diets and sustainable food production. It estimates that the transformation to healthy diets by 2050 will require that the world’s consumption of fruit, vegetables, nuts, seeds, and legumes doubles, and the consumption of foods such as red meat and sugar should be reduced by more than 50%.” That’s an important reminder, as over the past decades the diets of many people living around the Mediterranean have become Westernized and Western illnesses are gaining a foothold.

How can you adopt this way of life? The report “Mediterranean Diet as Intangible Heritage of Humanity: 10 Years On,” published in June 2021 in Nutrition, Metabolism & Cardiovascular Diseases, mentions making olive oil, described as a cornerstone of the Mediterranean diet, our main source of fat. It also talks about using the Mediterranean diet and the activities surrounding it as a global model for health and sustainability since “humanity as a whole will benefit from its preservation and scientific-based evidence.” 

The article in Nutrients outlines a guiding philosophy you might follow. It includes: 

  • Choosing fresh, locally produced foods
  • Connecting with and respecting nature
  • Cooking flavorfully
  • Eating moderate portion sizes
  • Doing moderate physical activity every day
  • Preparing and eating meals in the company of others

Quinoa: Tastes great, more filling

Cultivated for more than 5,000 years in the Andean region of South America, quinoa has become a high-protein plant food darling in the US. Though technically a seed, it’s often put into the whole grain category. But no matter what you call it, quinoa is a powerhouse of nutrition. One cup of cooked quinoa delivers about 5 grams of fiber and 8 grams of protein, and unlike most other grains, it’s a complete protein, meaning that it contains all nine essential amino acids. It’s also rich in manganese, phosphorus, magnesium, vitamin B1, and folate, according to Harvard Health. There are more than 120 known varieties of quinoa, from the mild-tasting white and yellow to the earthier red and black, whose shape holds up better after cooking. You can even pop it on the stove like popcorn.

Black beans: Know your options

It’s crazy easy to open a can of black beans, cooked and ready to reheat or add to a recipe. But it’s not really complicated to make them from scratch, plus you control the added salt—the chief drawback of canned beans. Store brands like Goya sell dried black beans, and they’re also available from Rancho Gordo and other online gourmet outlets. When convenience is key and you’re shopping for canned, look for sodium-free varieties, or drain and rinse the beans before using to remove as much salt as possible.

Air quality and your brain

It’s no secret that air pollution can be harmful, especially to our lungs, and it pays to stay indoors on poor air quality days. Now research shows that it can age our brains, too. A fascinating study looked at performance changes in people playing brain-training games and found that even short-term exposure to air pollution affects brain performance and the capacity to work, causing cognitive function damage. 

“The games we studied targeted seven cognitive functions: memory, verbal ability, attention, flexibility, math ability, speed, and problem-solving,” explains Andrea La Nauze, PhD, of the University of Queensland School of Economics. “We found that exposure to moderately high levels of fine particulate matter (PM2.5) caused a player to drop by almost six points on a 100-point scale where 100 represents the score of the top 1% of cognitive performers. In fact, if you’re under 30 years old and you’re exposed to this level of pollution, your cognitive function declines by the same amount as aging by 15 years.” 

PM2.5 are tiny particles 2.5 microns or smaller in size. If inhaled, they can get into the lungs, enter the bloodstream, and cause other serious health problems such as heart disease and respiratory issues. “Cognitive functions are skills that we use to process, store, and use information—they’re critical to tasks ranging from making a cup of tea to self-regulating,” she says. “Economists are just beginning to study cognition, but recent research suggests changes in cognitive function impact workforce productivity. Our results show the effects of air pollution are largest for those under 50—people of prime working age—which indicates that day-to-day performance in our jobs is also likely to be impacted. You can alter your exposure in small ways by staying indoors, using air filtration, or moving to a less-polluted suburb,” she says.

Lower your cancer risk with exercise

A study published in the journal Medicine & Science in Sports & Exercise and led by Adair Minihan, MPH, of the American Cancer Society, found that 3% of cancer cases—more than 46,000—could be prevented each year in the US if we met the recommended physical activity guidelines of 5 hours per week of moderate-intensity exercise.

This was the first study to estimate, state by state, the number of cancer cases linked to physical inactivity based on the location of the cancer (breast, endometrium, colon, stomach, kidney, esophagus, and urinary bladder). In terms of specific cancer sites, 16.9% of stomach cancers, 11.9% of endometrial cancers, 11.0% of kidney cancers, 9.3% of colon cancers, 8.1% of esophageal cancers, 6.5% of female breast cancers, and 3.9% of urinary bladder cancers were associated with a lack of exercise. By state, the proportion of cancer cases attributable to physical inactivity ranged from 2.3% in Utah to 3.7% in Kentucky.

For both men and women, states with the highest proportion of cancers attributable to physical inactivity were in the South, including Kentucky, West Virginia, Louisiana, Tennessee, and Mississippi; the lowest proportions were found in the Mountain region and northern states, including Utah, Montana, Wyoming, and Washington, as well as Wisconsin.

The study also highlighted the fact that many people have to overcome barriers in order to exercise, such as a lack of time because of work demands, the cost of a gym membership or home equipment, and even not having access to a safe environment in which to exercise. It may help to get involved in community programs and group activities, both to strengthen a commitment to exercise and to tap into its social benefits.

Mustards

Having a selection of mustards that go beyond the ubiquitous yellow adds versatility to your cooking. A classic Dijon brings a wonderful sharpness to vinaigrettes and crusts for fish and lamb; add some honey and you’ve got a sweet and tangy sandwich condiment. Grainy mustards, which use the entire mustard seed, have texture as well as a heartier flavor, making them a great addition to stews and soups, among other dishes.

Clean out your fridge for the new year

A New Year’s resolution that’s easy to keep and takes an hour at most is to do a clean sweep of your fridge. Most important is to check each item for its expiration date (of course, toss anything that looks or smells questionable, no matter the printed use-by date). Hard as it might be, throw out foods that you know you’re not going to use again, like that salsa you tried and just didn’t like or the jam that wasn’t as sweet as you expected. If you haven’t given the fridge itself a good cleaning lately, use a mild dish soap and paper towels to wipe down all the shelves, bins, and doors.

Putting the Spotlight on Potassium

It’s no secret that changing habits is hard. There have only been a few studies on how well we stick to New Year’s resolutions, and the findings say it’s not well at all. But research published in Frontiers in Psychology in 2018 found that having two types of goals can make a difference: They work together to get you where you want to go. There are big-picture goals, like being healthier or losing weight, which tend to be vague, and smaller, in-the-weeds goals that can be the building blocks of getting to the big target, like going to the gym twice a week or cutting out 100 calories a day. The smaller goals, which are very specific and time-oriented, need to be repeated until you reach the big-picture one, yet they serve as terrific motivation to keep you going.

A study on New Year’s resolutions published in 2020 in PlosOne found that some people do better with some support. This could be a session with a fitness trainer or a dietitian, who can provide information to help you reach your goals. 

Change is also easier to effect when it becomes second nature. In her book How to Change: The Science of Getting From Where You Are to Where You Want to Be (Penguin), Katy Milkman, PhD, a behavioral scientist and the James G. Dinan Professor at the Wharton School of the University of Pennsylvania, details research-backed tools to help make new habits stick. These include telling your partner or a close friend about your goal because it makes the commitment more real and you won’t want to risk embarrassment by not reaching it; linking a new habit to an existing one, like eating fruit when you take your morning vitamins; and setting smartphone reminders for walking breaks so you don’t have the excuse of forgetting to do them. It also helps to be flexible and not abandon your entire plan because of one slip here or there. 

Making permanent habits, rather than going on and off a regimen, really brings the best results in the long run.

Salmon with Blood Oranges and Olive Oil Recipe, Plus Learn How Fruits, Vegetables, Fish, Whole Grains and Fresh Pressed Olive Oil Can Effect Mental Health

The benefits of olive oil can be seen in almost every aspect of our health—and not only physical health, but mental health, too. Research has looked at how extra virgin olive oil, both on its own and as part of the Mediterranean diet, can be a helpful component in an overall plan to combat depression. That’s a powerful message. Cooking and sharing food with others are also powerful mood enhancers—one delicious way to do this is with my olive oil and orange baked salmon recipe!

A Surprising Benefit of Olive Oil: Easing Depression

The Research: 

Journal of the Academy of Nutrition and Dietetics, “Extra-Virgin Olive Oil Improves Depression Symptoms Without Affecting Salivary Cortisol and Brain-Derived Neurotrophic Factor in Patients With Major Depression: A Double-Blind Randomized Controlled Trial,” August 2021.

Nutrients, “The Relationship between Adherence to the Mediterranean Diet, Intake of Specific Foods and Depression in an Adult Population (45–75 Years) in Primary Health Care. A Cross-Sectional Descriptive Study,” August 2021.

BMC Medicine, “A randomised controlled trial of dietary improvement for adults with major depression (the ‘SMILES’ trial),” January 2017. 

Research has shown that olive oil included in your diet on a regular basis protects against depression, especially when part of a Mediterranean diet with lots of fruits, vegetables, fish, and whole grains. Research published in 2017 in BMC Medicine looked at whether the diet could help treat major depression as well. Participants who got personalized nutritional consulting from a dietitian, including goal setting and mindful eating, and followed the Mediterranean diet had significantly greater improvement after 12 weeks than did participants who didn’t get that comprehensive plan. On a daily basis, the helpful diet included 3 tablespoons of olive oil, 5–8 servings of whole grains, 6 servings of vegetables, 3 servings of fruit, 2–3 servings of low-fat unsweetened dairy foods, and a serving of raw, unsalted nuts; and on a weekly basis, 3–4 servings of legumes, at least 2 servings of fish, 3–4 servings of lean red meat, 2–3 servings of chicken, and up to 6 eggs. At the same time, sweets, refined cereals, fried food, fast food, processed meat, and sugary drinks were limited to no more than 3 per week. 

A pair of recent studies built on these findings. The study in Journal of the Academy of Nutrition and Dietetics found that having 25 mL of extra virgin olive oil (about 5 teaspoons) every day for 52 days led to a significant improvement in depression symptoms among study participants with severe depression, making it a potential complementary therapy to mental health counseling and medication. 

The Nutrients study took a more global view, similar to the one in BMC Medicine, investigating the effects of the Mediterranean diet along with the roles of specific foods. It also looked at depression from the opposite point of view—which foods are linked to depression. The researchers came to this positive conclusion: “Adherence to the Mediterranean diet and the resulting consumption of nuts, vegetables, and olive oil has been found to relate to a lower presence of depressive symptomatology. On the other hand, a poorer adherence to the Mediterranean diet and an excessive consumption of sugary drinks and red meats has been related to higher depressive symptomatology.” In view of this, they pointed out that assessing the diet of people with depression could help in development of a treatment plan. Of course, it’s important to keep in mind that diet is just one facet of depression care; the researchers added that “depression is a very complex issue and the relationship between nutrition and depression must be further examined to obtain additional scientific evidence.”
