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.

Should You Stretch before Exercise? After? Never? Here’s What to Know

For many people of a certain age, high school gym class began with reaching for their toes. Then, over the years, we were told it was better to stretch after exercise.

It turns out, both those things can be true, but the differing advice has created some confusion.

Stretching can help make you more flexible, improve range of motion in your joints — and feel good. David Behm, who researches human kinetics at Memorial University of Newfoundland in St. John’s, Canada, offers this advice on when to stretch and how to do it safely:

Warm up first

It’s almost always good to stretch, but it’s better if you warm up first, said Behm, author of "The Science and Physiology of Flexibility and Stretching." He recommends a light aerobic activity such as jogging, walking or cycling for five or 10 minutes.

Follow that with some static stretching, the traditional way of reaching and holding a position (think back to that gym class). You can then do activity-specific dynamic stretching, in which you warm up the muscles with repetitive movements like leg lifts.

Behm says one minute is "the magic number" for how long to do static stretching per muscle group without fatigue.

Expand your definition of 'stretching'

Should you always stretch before exercising? If it's traditional stretching, not necessarily.

The better question, Behm says, is, "Should people increase their range of motion? Should people have better flexibility? And that is yes, because it helps prevent injuries. It helps with health. But you don’t have to stretch to achieve that."

Resistance training, for instance, can be an effective form of stretching, he said. Doing a chest press increases range of motion in your deltoids and pecs, whether with barbells, dumbbells or machines, so there is no need to stretch beforehand. Just make sure to start with a small amount of weight to warm up and then add more to train.

"You probably don’t have to do extra stretching unless you’re a gymnast, a figure skater, or even a golfer who needs a great range of motion through that swing," Behm said.

Nor do you need to stretch first if you’re going for a leisurely run. Simply start with a slow jog to warm up and then increase the pace.

Don't do it if it hurts

After exercise, "light stretching is OK, as long as you don't reach a point where you're feeling pain," Behm said. Since your muscles will be warm by that point, overdoing it makes you more likely to injure yourself.

Foam rollers can help with muscle recovery and have been shown to increase range of motion as well as stretching.

Do some static stretching before sports

If you’re playing a sport, Behm said, static stretching beforehand helps reduce muscle and tendon injury.

"If you’re going to do an explosive movement, change of direction, agility, sprint, any of these explosive activities that involve your muscles and tendons," he said, "you’re going to be stronger if you do static stretching."

People can especially get in trouble when they go back to a sport they used to play, whether it's tennis, surfing or any sort of team activity.

Also, stretch both sides equally. Lacking flexibility on one side also can lead to injury.

Sounds simple. Why all the confusion? Different studies over the years have either encouraged or discouraged stretching before exercise. Behm says that partly because some studies didn't reflect real-life conditions, or were designed with elite athletes in mind, not regular people.

"If you’re Usain Bolt, it makes a difference," said Behm. Not so much for the rest of us.
