Churrascas Recipe, Spotlight on Extra Virgin Olive Oil for Cooking, The Right Rolling Pin for the Job, More Concerns over Ultra-processed Foods, and Travel: The New Fountain of Youth
I came back from my most recent trip to Chile with more recipes than could fit in the Pressing Report, so I’m sharing the first one of two with you here. Delicious and easy-to-make churrascas, traditional Chilean flatbreads, cook up fast on the stovetop. They’re perfect for filling taco-style with grilled meat cubes, topping with shredded cheese and salsa, slicing in half for sandwiches, or simply drizzling with fresh-pressed Chilean olive oil! Then check out new research on the risks of eating ultra-processed foods, plus more evidence of the positive effects of travel.
Churrascas
ChurrascasChurrascas are a great last-minute homemade bread because the dough needs just a short amount of rest after kneading. While this recipe calls for making them on the stovetop, you can also make them on your grill, cooking as many as will fit all at once. Do enjoy them right away, while they’re still soft and pillowy. Note: Don’t confuse churrasca the bread with churrasco the grilled meat that’s often stuffed into a sandwich—you will find a great recipe for that in the current Chilean Pressing Report.
Ingredients
- 4 cups all-purpose flour
- 2 teaspoons coarse sea salt
- 1/2 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 cup olive oil
- 3/4 cup warm tap water, to start
Directions
Step 1
In the bowl of a stand mixer or a large bowl, whisk together the dry ingredients. Combine the oil and 3/4 cup water in a measuring cup, whisk, and add to the bowl; stir to make a dough ball. If the dough is raggy, add additional water, 1 tablespoon at a time. Knead with the dough hook attachment for 5 minutes or by hand for 10 minutes until smooth.
Step 2
Turn out the dough and cut into 6 portions. Roll each one into a ball, then roll them out, one at a time, with a rolling pin, doing quarter-turns until about 5 inches in diameter and about 1/4-inch thick. Rest the dough for 30 minutes.
Step 3
Heat a griddle, preferably cast iron, over medium heat. When the pan is hot, add two churrascas and cook for about 5 minutes, turn with tongs, and cook for another 4 to 5 minutes. Repeat twice more with the rest of the rounds.
Yields 6 churrascas

Extra Virgin Olive Oil for Cooking
While many Fresh-Pressed Olive Oil Club members love drizzling EVOO on food or even sipping it as a daily health ritual, olive oil is also meant for cooking. I was pleased when, in 2019, the famed Culinary Institute of America (CIA) put out a whitepaper promoting olive oil to improve the health of the planet and its inhabitants, declaring it to be the best cooking fat from a health and sustainability perspective. What’s more, CIA recommended olive oil for all methods of cooking, including high-heat frying, dismissing the myth about a low smoke point. I encourage you to expand your olive oil recipe repertoire.
Quick Kitchen Nugget
The Right Rolling Pin for the Job
If you only have one rolling pin, make it atapered French rolling pin, say expert bakers. It’s a single solid piece of wood that tapers at the ends. The tapered ends allow your fingers to wrap around the wood for good downward pressure and make it easier to make the quarter-turns needed for smooth dough with uniform thickness.
The second one to have in your kitchen is a dowel or cylindrical rolling pin. It’s great for gettingeven thickness across large sheets of dough, no matter what thickness you need to achieve. This straight-shaped rolling pin has the same consistent diameter along its entire length.
The common American or roller-style pin has handles on either end that rotate on internal bearings, so you can push down firmly without gripping the roller. It’s best for stiffer doughs, like cookies.

More Concerns over Ultra-processed Foods
A new study, published in Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, a journal of the Alzheimer’s Association, suggests that eating more ultra-processed foods (UPFs) could make it harder to stay focused and may contribute to factors linked to dementia, even among people who otherwise follow healthy diets. UPFs include products such as soft drinks, packaged salty snacks, and ready-made meals. Unlike fresh or minimally processed foods, these products undergo extensive industrial processing.
Researchers from Monash University, the University of São Paulo, and Deakin University analyzed dietary and cognitive data from more than 2,100 middle-aged and older Australian adults who did not have dementia. They used data from the Healthy Brain Project, which is supported by the National Health and Medical Research Council, the Alzheimer’s Association, the Dementia Australia Research Foundation, the Bethlehem Griffiths Research Foundation, the Yulgilbar Alzheimer’s Research Program, the National Heart Foundation of Australia, and the Charleston Conference for Alzheimer’s Disease. Participants in the study obtained about 41 percent of their daily calories from ultra-processed foods, nearly matching the Australian national average of 42 percent.
The study found that even modest increases in ultra-processed food consumption were associated with measurable declines in attention and mental processing speed. Lead author Dr. Barbara Cardoso, from Monash University’s Department of Nutrition, Dietetics and Food and the Victorian Heart Institute, said the results add to growing evidence linking highly processed foods to poorer brain health. “To put our findings in perspective, a 10 percent increase in UPFs is roughly equivalent to adding a standard packet of chips to your daily diet,” Dr. Cardoso said. “For every 10 percent increase in ultra-processed food a person consumed, we saw a distinct and measurable drop in a person’s ability to focus. In clinical terms, this translated to consistently lower scores on standardized cognitive tests measuring visual attention and processing speed.”
One of the study’s most notable findings was that the negative effects on attention appeared regardless of a person’s overall diet quality. Even participants who generally followed a healthy Mediterranean-style diet showed the same relationship between greater ultra-processed food intake and poorer focus. According to the researchers, this suggests that the level of processing itself may play an important role.
“Food ultra-processing often destroys the natural structure of food and introduces potentially harmful substances like artificial additives or processing chemicals,” Dr. Cardoso said. “These additives suggest the link between diet and cognitive function extends beyond just missing out on foods known as healthy, pointing to mechanisms linked to the degree of food processing itself.”
The researchers also found that higher consumption of ultra-processed foods was associated with an increase in known dementia risk factors. These include conditions such as obesity and high blood pressure, both of which can be managed to help support long-term brain health. While the study did not identify a direct link between ultra-processed foods and memory loss, the researchers note that attention is a fundamental cognitive function. It plays a critical role in learning, problem-solving, and many other mental tasks. Because attention serves as the foundation for so many aspects of thinking, declines in focus may represent an important early warning sign of broader cognitive changes.

Travel: The New Fountain of Youth
New research from Edith Cowan University (ECU) reinforces the idea that travel can be a surprisingly powerful anti-aging tool. Researchers found that positive travel experiences may help the body stay balanced and resilient. Activities like exploring new places, staying active, and connecting with others can boost immunity, metabolism, and stress recovery. However, stressful or unsafe travel could reverse these benefits.
In 2024, we reported on ECU’s interdisciplinary study published in the Journal of Travel Research, for which researchers applied the theory of entropy to tourism, proposing that positive travel experiences may support physical and mental health in ways that could help slow some signs of aging. The work does not suggest that travel can stop aging, but it frames tourism as more than a break from routine. It may be a way to help the body maintain balance, resilience, and repair.
Entropy is often described as the universe’s movement toward disorder. In the context of health, the researchers suggest that experiences can either support or disrupt the body’s ability to stay organized and functioning well. Positive travel experiences may help reduce that drift toward disorder, while stressful or unsafe travel may push the body in the opposite direction.
Since the 2024 study, related work has continued to explore travel therapy as a possible health and wellness approach. A 2025 research note by ECU PhD candidate Ms. Fangli Hu and colleagues described travel therapy as an emerging approach in which positive travel experiences may promote well-being, while also emphasizing the need to weigh benefits against risks.
Another 2025 paper called for closer collaboration between travel medicine and tourism, reflecting a growing interest in how vacations, health risks, preventive care, and traveler well-being overlap. A 2025 systematic review also found that tourism and healthy aging is becoming an important interdisciplinary research area but remains underexplored and in need of stronger methods and clearer future research directions.
Together, these newer findings support a careful interpretation: travel may offer real health-related benefits, especially when it includes movement, social connection, novelty, and restoration, but researchers are still working to understand how strong those effects are and who benefits most.
“Aging, as a process, is irreversible. While it can’t be stopped, it can be slowed down,” Ms. Hu said, explaining that travel may improve well-being by placing people in new environments, encouraging movement, increasing social interaction, and creating positive emotions. Those same ideas already appear in areas such as wellness tourism, health tourism, and yoga tourism.
“Tourism isn’t just about leisure and recreation. It could also contribute to people’s physical and mental health,” Ms. Hu added.
Viewed through an entropy lens, travel therapy could become a meaningful health intervention, Hu said. The idea is that positive travel experiences, as part of a person’s environment, may help the body maintain a healthier low-entropy state by influencing four major body systems.
Travel often combines unfamiliar surroundings with relaxing experiences. New settings can stimulate the body, raise metabolic activity, and help activate self-organizing processes that keep biological systems working smoothly. These experiences may also prompt the adaptive immune system, which helps the body recognize and respond to outside threats.
Ms. Hu said that this reaction improves the body’s ability to perceive and defend itself against external threats: “Put simply, the self-defense system becomes more resilient. Hormones conducive to tissue repair and regeneration may be released and promote the self-healing system’s functioning.”
Relaxing travel activities may also help reduce chronic stress and calm an overactive immune response. Recreation can ease tension and fatigue in the muscles and joints, supporting metabolic balance and strengthening the body’s ability to resist wear and tear.
This matters because travel is rarely just sitting still. Trips often include walking through cities, hiking trails, climbing, cycling, or simply spending more time on your feet than usual. That physical activity can increase metabolism, energy use, and nutrient movement throughout the body, all of which may support the systems that keep the body repaired and resilient.
“Participating in these activities could enhance the body’s immune function and self-defense capabilities, bolstering its hardiness to external risks. Physical exercise may also improve blood circulation, expedite nutrient transport, and aid waste elimination to collectively maintain an active self-healing system. Moderate exercise is beneficial to the bones, muscles, and joints in addition to supporting the body’s anti-wear-and-tear system,” Ms. Hu said.
The same research also cautions that travel is not automatically healthy. Tourists can face infectious diseases, accidents, injuries, violence, unsafe food or water, and other risks linked to poor planning or unsuitable travel choices. “Conversely, tourism can involve negative experiences that potentially lead to health problems, paralleling the process of promoting entropy increase. A prominent example is the public health crisis of COVID-19,” said Hu.
The central message is not that any trip will slow aging. Rather, positive travel experiences may help the body and mind function better by combining novelty, relaxation, physical activity, and social connection. When travel is safe, restorative, and active, it may do more than create memories. It could help support healthier aging from the inside out.
