A small everyday addition could sharpen the mind from morning light to evening fatigue. New research from the University of Reading suggests that including a handful of walnuts in a breakfast can measurably enhance mental performance across the day. The study, published in Food & Function, followed 32 healthy adults aged 18 to 30 who ate a walnut-rich breakfast on some days and a calorie-matched, nut-free breakfast on others. Over six hours, participants underwent cognitive testing and brain activity measurements, revealing meaningful differences in performance.

Could the humble walnut hold the secret to keeping your mind sharp from breakfast until dusk? Recent findings by researchers at the University of Reading strongly suggest so, with evidence now showing that simply adding a handful of walnuts to your morning meal can measurably improve mental performance throughout the day. The study, published in the scientific journal Food & Function and widely reported by reputable news outlets including The Independent (source: The Independent), tracked 32 healthy young adults, aged 18 to 30, who consumed either a walnut-rich breakfast or a calorie-matched breakfast without nuts on different occasions. Their subsequent six hours were filled with cognitive testing and brain activity measurements—yielding results with significant implications for anyone seeking a mental edge in daily life.

A sweeping new review of scientific studies suggests a strong connection between vitamin D and reduced risk of colorectal cancer, with some findings indicating up to a 58% lower risk among those with the highest vitamin D intake. This revelation, published in April 2025 in the journal Nutrients, could have far-reaching implications for cancer prevention strategies in Thailand and across the globe, offering a natural, affordable, and accessible way to combat one of the world’s most common and deadly cancers (EatingWell).

Fresh research brings an age-old saying back into the spotlight—eating two apples a day may not only keep the doctor at bay, but can also “significantly” lower your cholesterol, according to a study highlighted in recent UK news coverage. For Thai readers increasingly mindful of cardiovascular health, this breakthrough aligns with global shifts towards embracing dietary solutions to chronic diseases. With heart disease and stroke rankings remaining high among causes of death in Thailand, this simple dietary tweak could offer a practical, affordable shield for millions.

France’s top food safety agency, ANSES (Agence nationale de sécurité sanitaire de l’alimentation, de l’environnement et du travail), has sent shockwaves through the international nutrition community with its latest recommendation: soy-based foods should be banned from all public mass catering, including schools, hospitals, and care homes. This call, issued in March 2025, has ignited global debate over the safety of soy products—a topic relevant to Thailand as plant-based menus become increasingly popular in schools and health-conscious households.

A French health agency has sparked a global conversation about soy in public catering, including schools, hospitals, and care homes. In March 2025, ANSES emphasized caution around high-intensity soy consumption, focusing on isoflavones, the plant compounds that can act like estrogen in the body. The agency warned that excessive intake could influence hormone balance and potentially affect children’s development if exposure is prolonged. Thai readers should note the emphasis on balanced nutrition and moderation as schools increasingly explore plant-based proteins.

A comprehensive review of 50 high-quality studies finds a meaningful link between higher vitamin D levels and lower colorectal cancer risk. Some studies suggest up to a 58% reduction among individuals with the highest intake, a finding that could influence cancer prevention strategies in Thailand and beyond. The research, published in Nutrients in 2025, emphasizes vitamin D as a practical and accessible tool in public health.

Colorectal cancer remains a major global health challenge, ranking among the most common cancers for both men and women. In Thailand, the disease has become more prevalent in recent years, with dietary shifts toward processed foods and lower fiber intake contributing to risk. Public health leaders are urging culturally appropriate prevention efforts that align with Thai lifestyles and dietary patterns.

New findings revive a familiar habit with real potential for Thai readers: eating two apples daily may significantly lower cholesterol, supporting cardiovascular health. This simple, affordable dietary change aligns with Thailand’s growing focus on prevention and everyday wellness.

Hypercholesterolemia, or high cholesterol, means excess fatty substances circulate in the bloodstream. Over time, this can lead to blocked blood vessels, increasing the risk of heart attacks and strokes—a major concern for Thai families and the healthcare system. Diets high in saturated fats are well documented as a driving factor, a point that resonates in Thailand where coconut milk and fried foods are common components of traditional meals.

A recent study from the University of Reading has brought a simple but impactful message to breakfast tables around the world, including Thailand: adding just a handful of walnuts to your morning meal could significantly enhance your brain function throughout the day. This research, published in the journal Food & Function, found that young adults who consumed 50 grams of walnuts with their muesli and yoghurt at breakfast enjoyed faster reaction times and improved memory performance, but with interesting timing differences—memory benefits were especially notable later in the day compared to those who ate a calorie-matched breakfast without nuts (The Independent, University of Reading, Sci.News).

A trip to the supermarket these days is as much a marketing battleground as a chance to stock up on groceries. With promises like “heart healthy,” “high in protein,” and “low-carb” splashed across everything from yogurt to granola bars, health-conscious Thai shoppers may feel reassured about their food choices. But new research and mounting global scrutiny reveal that these claims are often more about sales than substance—prompting both consumers and regulators to rethink how healthy our processed foods really are (Yahoo Lifestyle, 2025).

A new study from Weill Cornell Medicine links a common cooking oil fat to aggressive breast cancer, specifically triple-negative breast cancer (TNBC). While the finding adds to important scientific discussions, Thai researchers urge caution and context. Nutrition decisions should be balanced and based on overall diet, not on a single study or ingredient.

In Thailand, everyday cooking often relies on soybean, sunflower, and corn oils. These oils are rich in linoleic acid, an omega-6 fatty acid essential for health but contested in current research. The New York study suggests linoleic acid can activate pathways that may promote TNBC growth in certain biological contexts, particularly when the FABP5 protein is also elevated. Researchers observed in animal studies that this interaction can trigger the mTORC1 pathway, which drives cell growth and metabolism, potentially accelerating tumor progression. Patients with TNBC showed higher levels of both FABP5 and linoleic acid in their blood, according to the study.

A new study led by a researcher at East Tennessee State University aims to tackle vitamin deficiencies that affect millions. With a $450,000 grant from a foundation focused on food and agriculture, the team uses machine learning and rapid robotic screening to boost the vitamin content of staple seeds, starting with soybeans. This work offers a practical path to healthier diets worldwide, including in Thailand.

For Thai audiences, the relevance is clear. Thailand has reduced severe malnutrition over the years, but micronutrient gaps—iron, vitamin A, and folate—persist among vulnerable groups such as rural children, pregnant women, and urban poor. These hidden deficiencies can stunt growth and lower productivity. Data from UNICEF Thailand underscores the priority of improving micronutrient intake in Southeast Asia, where rice-based diets often lack diversity.

A surprising twist in the search for longer, healthier lives has surfaced, and it began not in a high-tech lab but among US Navy dolphins. Scientists studying age-related diseases in these marine mammals uncovered a fatty acid, known as C15:0, that’s now being recognized as a potential “longevity nutrient” for humans—with research suggesting this overlooked nutrient could play a crucial role in fighting everything from fatty liver disease to heart disease, diabetes, and even aging itself (IFLScience).

A groundbreaking study led by Dr. Tianhu Sun of East Tennessee State University (ETSU) aims to tackle one of the world’s most pervasive but invisible health issues: vitamin deficiencies. Armed with a $450,000 grant from the Foundation for Food and Agriculture Research, Dr. Sun and his team are harnessing advanced genetic tools — including machine learning and high-throughput robotic screening — to enhance the vitamin content of staple crop seeds, starting with soybeans. This innovative approach promises realistic, sustainable solutions for improving the nutrient profile of everyday foods worldwide, a change that could echo meaningfully in Thailand and beyond (SciTechDaily).

A recent scientific breakthrough has linked a common fat found in everyday cooking oils to the growth of aggressive forms of breast cancer—specifically, triple-negative breast cancer. But leading researchers caution Thai consumers not to rush to abandon their favorite oils just yet, emphasizing context and the importance of a balanced diet, rather than panic or rash dietary changes. The findings, published by a research team from Weill Cornell Medicine in New York and recently summarized in an article by The Conversation (source), have generated a lively debate across both global medical circles and Thai health forums.

A surprising development in the quest for healthier aging comes from an unlikely source: dolphins studied by researchers at a U.S. Navy facility. Scientists found that a fatty acid called C15:0 may act as a longevity nutrient for humans, potentially helping prevent fatty liver disease, heart disease, diabetes, and age-related decline. Research points to C15:0 as a nutrient we may need to consider more carefully in diets and supplements.

For Thai readers, this topic matters beyond science headlines. In The Longevity Nutrient: The Unexpected Fat That Holds the Key to Healthy Aging, researchers describe how dolphins with higher C15:0 levels tended to maintain better metabolic health. The fatty acid is present in some marine foods and, importantly, in whole-fat dairy products like milk and butter, suggesting practical dietary avenues to explore.

Shopping today often feels like navigating a marketing contest as much as choosing groceries. Labels such as “heart healthy,” “high in protein,” and “low-carb” appear on everything from yogurt to granola bars. New research and regulatory scrutiny suggest these claims are sometimes more about sales than substance, prompting consumers and authorities to reassess how healthy processed foods really are.

Why this matters for Thailand. Diet-related health issues—rising obesity, type 2 diabetes, and heart disease—are shaping health outcomes across Asia. As more Thais rely on convenient, processed foods, marketing tactics can influence public health efforts. For shoppers trying to make informed choices, front-of-pack claims can be misleading or confusing, masking the true nutritional quality of products.

A recent study from the University of Reading suggests a tiny morning tweak can sharpen thinking for the day ahead. Eating a handful of walnuts with breakfast improved reaction times and memory performance in healthy young adults. The researchers found that memory benefits emerged later in the day, strengthening the case for nuts as a practical brain boost.

For Thai readers, where commutes, classes, and busy workdays demand sustained mental sharpness, this finding is especially relevant. Cognitive lapses are often chalked up to sleep, stress, or distractions. This study indicates a straightforward dietary adjustment could help students and professionals stay alert throughout their routines.

Protein has long been crowned the “macronutrient king”—the building block behind strong muscles, healthy skin, shiny hair, and a satisfied, full feeling after meals. Yet even as high-protein diets trend on social media and more Thais opt for protein shakes or add an extra egg to their khao tom, new research and expert advice reveal that it’s surprisingly easy to fall short on daily protein needs, and the effects may be more subtle—and more important—than most people realise source.

As probiotics continue to line the shelves of Bangkok supermarkets and pharmacies, more Thai consumers—สุขภาพดีอยู่แล้ว—are asking: should I be adding these “good bacteria” to my daily routine, or is a fibre-rich ผักและผลไม้ diet enough for a healthy gut? The newest research, including a comprehensive 2024 review in Advances in Nutrition, brings clarity to the probiotic puzzle, offering practical advice amidst the booming global wellness trend.

For Thailand, where fermented foods like น้ำพริก, เต้าเจี้ยว, and yogurt-based drinks are everyday staples, the appeal of packaged probiotics is both a product of globalization and increased health consciousness. Advertisements promise improved digestion, better immunity, enhanced mood, and even weight management, but what does the science say about real benefits for already healthy people? And how does this apply to the Thai lifestyle, richly intertwined with traditional diets and home remedies?

The sizzling question of whether cooking with olive oil destroys its precious nutrients has long lingered in Thai kitchens, especially as more families embrace olive oil for both flavor and health. A recent interview with food scientist Jessica Gavin, featured in an article published April 14, 2025, by EatingWell, unpacks the science and sets the record straight: while cooking does cause some nutrient loss—mainly antioxidants—olive oil remains one of the healthiest and most versatile fats for everyday use, so long as it’s used within recommended temperature limits (EatingWell).

Strolling down the aisles of any modern supermarket, shoppers from Bangkok to Buriram are awash in attractive food packaging touting claims like “heart healthy,” “high in protein,” or “low-carb.” But intriguing new research and regulatory discussions are challenging whether these tempting promises really hold up—and how consumers in Thailand and worldwide might be misled by what’s known as “nutriwashing” or “healthwashing” Yahoo.

What is nutriwashing? Marketers routinely use buzzwords like “natural,” “gluten-free,” and “immune-boosting” to confer a health halo on processed foods. Yet, as Lindsay Malone, a registered dietician and nutrition instructor at Case Western Reserve University, tells Yahoo Life, “These claims influence consumer decisions by creating the illusion of healthiness, leading shoppers to choose products they believe are better for them when, in reality, they may still be highly processed and nutritionally poor.” Her warning echoes international studies that found many foods labeled as “high in protein” or “whole grain” may contain surprisingly high levels of sugar, artificial sweeteners, and preservatives PubMed, 2024.

A robust new clinical trial has revealed that fish oil supplements deliver higher levels of vital omega-3 fatty acids to the body compared to eating fish, challenging the long-standing notion that whole foods are always superior to supplements for nutrient intake (Good News Network). The study, recently published in the British Journal of Nutrition, provides fresh evidence that could influence dietary advice in Thailand, where cardiovascular disease and other non-communicable diseases continue to pose significant public health threats.

A growing question in Thai homes is whether cooking with olive oil drains its nutrients. A recent interview with food scientist Jessica Gavin, referenced in an EatingWell article from April 14, 2025, clarifies the science: heating can cause some nutrient loss—especially antioxidants—but olive oil remains among the healthiest fats for daily use when kept within recommended temperatures.

Olives oil’s popularity isn’t limited to the West. In Bangkok, Chiang Mai, and other cities, households are swapping pork lard or palm oil for olive oil in cooking and dressings. The appeal lies in heart health support, reduced inflammation, and alignment with the Mediterranean diet—often cited for longevity. Yet many Thai cooks wonder if high-heat methods like stir-frying or deep-frying strip olive oil of its benefits.
