The Mediterranean diet isn’t like other diets. To begin with, it’s more of a style of eating than a strict regimen. And adopting it doesn’t involve many of the sacrifices people associate with healthy eating.

Compared with other wholesome diets, for example, the Mediterranean diet is relatively high in fat. Federal health officials recommend that 20 to 35 percent of your daily calories come from fat — while that number can be around 30 to 40 percent in the Mediterranean diet.

Yet in clinical trials, people who followed the Mediterranean diet had lower blood pressure and cholesterol levels and were less likely to develop cardiovascular disease than those who followed a low-fat diet.

That’s probably because the Mediterranean diet emphasizes heart-healthy fats from sources like olive oil, fish, whole grains, and nuts and seeds. And it includes less saturated fat than the typical American diet, because it discourages butter and red and processed meats and includes only moderate amounts of cheese, yogurt, poultry and eggs.

Researchers believe that olive oil, the preferred fat source in the Mediterranean diet, may be one of the main contributors to its health benefits. It’s rich in heart-healthy monounsaturated fats and has antioxidant and anti-inflammatory properties that can prevent damage to your cells and blood vessels.

In a 2022 study of more than 90,000 U.S. adults spanning 28 years, for instance, those who consumed at least half a tablespoon of olive oil each day were significantly less likely to die of cancer or cardiovascular, neurodegenerative or respiratory diseases than those who rarely or never consumed it.

Fish also features prominently in the Mediterranean diet, especially fatty varieties like salmon, tuna, anchovies and sardines. These are excellent sources of omega-3 fatty acids, which can improve blood cholesterol levels and reduce inflammation and blood pressure. Most Mediterranean diet guidelines recommend at least two servings of fish per week.

But let’s not give olive oil and fish all of the credit. Whole grains, nuts, seeds and olives also contribute to the diet’s healthy fats. And though they’re not native to the Mediterranean region, avocados are rich in monounsaturated fats and are often included in modern versions of the diet.

How to cook with healthy fats

For each day of our Mediterranean diet series, we and our colleagues at NYT Cooking have picked a few recipes that embrace the ingredients we’re highlighting. This is not intended to be a meal plan for a day, but rather inspiration for how to include more of these healthful foods in your week.

For breakfast, you might smash some avocado onto whole-grain toast and top it with a drizzle of olive oil. In this recipe from Julia Moskin and Giles Russell, optional garnishes like fresh herbs, pickled red onions and pumpkin or sesame seeds take avocado toast to the next level.

Craig Claiborne’s classic tuna salad sandwich is a quick, budget-friendly lunch option — but if you’re looking for something more “intense and pronounced,” try Ali Slagle’s sardine salad on a whole-wheat bagel, over greens or between two slices of whole-grain toast. Anchovies are also a flavorful addition to salad dressing, as in David Tanis’s vibrant radicchio-anchovy salad.

For dinner, try Alison Roman’s slow-roasted citrus salmon with herb salad (ready in 35 minutes) or Mark Bittman’s grilled tuna with herbs and olives (ready in 20). And let’s not forget about tinned and jarred fish.

The anti-obesity drug Ozempic could slow down ageing and has “far-reaching benefits” beyond what was imagined, researchers have suggested.

Multiple studies have found semaglutide (available under the brand names Wegovy and Ozempic) reduced the risk of death in people who were obese or overweight and had cardiovascular disease without diabetes, The Independent reported.

Responding to research published in JACC, the flagship journal of the American College of Cardiology, Professor Harlan M Krumholz from the Yale School of Medicine, said: “Semaglutide, perhaps by improving cardiometabolic health, has far-reaching benefits beyond what we initially imagined.”

He added: “These ground-breaking medications are poised to revolutionise cardiovascular care and could dramatically enhance cardiovascular health.”

Multiple reports also quoted Professor Krumholz saying: “Is it a fountain of youth?”

He said: “I would say if you’re improving someone’s cardiometabolic health substantially, then you are putting them in a position to live longer and better.

“It’s not just avoiding heart attacks. These are health promoters. It wouldn’t surprise me that improving people’s health this way actually slows down the ageing process.”

The studies, presented at the European Society of Cardiology Conference 2024 in London, were produced from the Select trial which studied 17,604 people aged 45 or older who were overweight or obese and had established cardiovascular disease but not diabetes.

They received 2.4 mg of semaglutide or a placebo and were tracked for more than three years.

A total of 833 participants died during the study with 5 percent of the deaths were related to cardiovascular causes and 42 per cent from others.

Infection was the most common cause death beyond cardiovascular, but it occurred at a lower rate in the semaglutide group than the placebo group.

People using the weight-loss drug were just as likely to catch Covid-19, but they were less likely to die from it – 2.6 percent dying among those on semaglutide versus 3.1 per cent on the placebo.

Researchers found women experienced fewer major adverse cardiovascular events, but semaglutide “consistently reduced the risk” of adverse cardiovascular outcomes regardless of sex.

Dr Benjamin Scirica, lead author of one of the studies and a professor of cardiovascular medicine at Harvard Medical School, said: “The robust reduction in non-cardiovascular death, and particularly infections deaths, was surprising and perhaps only detectable because of the Covid-19-related surge in non-cardiovascular deaths.

“These findings reinforce that overweight and obesity increases the risk of death due to many etiologies, which can be modified with potent incretin-based therapies like semaglutide.”

Dr Jeremy Samuel Faust, an emergency medicine physician at Brigham and Women’s Hospital, praised the researchers for adapting the study to look at Covid-19 when the pandemic started.

He said the findings that the weight-loss drug to reduce Covid-19 mortality rates were “akin to a vaccine against the indirect effects of a pathogen.”
