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.

Climate Change Causing More Change in Rainfall, Fiercer Typhoons, Scientists Say

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
