A Pew Research Center survey shows rising food costs are making healthy eating harder for Americans. Nearly seven in ten adults say price is a major obstacle, a finding that echoes in Thailand as households navigate similar pressures and changing food choices.

The poll, conducted in late February to early March 2025 with more than 5,100 American adults, found that 90% noticed higher prices for healthy foods in recent years. Even more striking, 69% say these costs hinder their ability to maintain a nutritious diet. The burden is heaviest for those on lower or fixed incomes, where 47% report difficulty versus 15% among higher-income families. This gap underscores how socioeconomic status shapes dietary health.

Higher food prices in the United States are making it increasingly difficult for Americans to maintain a healthy diet, with nearly seven in ten adults citing cost as a significant obstacle, according to a recent survey by the Pew Research Center. The findings resonate globally, including in Thailand, where economic pressures and changing food environments similarly influence dietary health.

The national survey, conducted in late February to early March 2025 and involving over 5,100 American adults, revealed that a staggering 90% of respondents observed price hikes in healthy foods over recent years. Most strikingly, 69% reported that these rising costs are hindering their ability to eat a nutritious diet. Those on lower or fixed incomes experienced the greatest hardships, with 47% facing particular difficulty compared to just 15% among higher-income households—a gap that highlights the stubborn link between socioeconomic status and nutritional health (CNN).

A new study from the University of Chicago shows that a Western-style diet—heavy in processed foods, red meat, dairy, and sugar, and low in plant-based fiber—impairs the gut’s ability to rebound after antibiotic treatment. Published in a leading science journal, the research has clear implications for Thailand as global food trends influence local eating patterns. For Thai audiences, it underscores the power of traditional, fiber-rich dishes in supporting health.

Data from the study indicate that what we eat shapes not only the diversity of the gut microbiome but also how quickly the ecosystem recovers after medical interventions. Thailand’s traditional cuisine, rich in vegetables, herbs, and fermented foods, naturally aligns with these findings and offers a practical path to better gut resilience.

Recent nutrition guidance underscores dietary fiber as essential for digestion, heart health, and metabolic well-being. A recent briefing synthesizes advice from registered dietitians, noting that most adults fall short of daily fiber targets. For Thailand, where average fiber intake trails national recommendations, the message carries added urgency for public health and personal wellness.

Fiber supports gut health, helps control appetite, and lowers the risk of high cholesterol, diabetes, and some cancers. The general daily targets are 21–26 grams for women and 30–38 grams for men. Surveys in the United States show only about 5% of adults meet these guidelines, a pattern echoed in several countries, including Thailand. In local studies, Thai adults’ mean daily fiber intake hovers around 9 grams, with even lower figures among those with chronic diseases. This aligns with global trends of under-consumption of vegetables, fruits, whole grains, and legumes—the core fiber sources.

Recent nutrition research continues to champion dietary fiber as a key pillar of healthy living, and new recommendations are highlighting specific foods that can make it easier—and more delicious—to meet daily fiber needs. A report published on Martha Stewart’s website, drawing on advice from registered dietitians, emphasizes that most adults fail to eat sufficient fiber, with far-reaching implications for digestive, metabolic, and heart health (Martha Stewart). For Thailand, where the average daily fiber intake remains well below recommended levels, this message carries particular urgency.

A new survey from the Pew Research Center reveals a complex portrait of American eating habits in 2025, highlighting how escalating food prices and evolving lifestyles are making healthy eating more challenging for many. This comprehensive analysis sheds light on the balance between taste, convenience, affordability, and healthiness, revealing key insights that resonate even for readers in Thailand navigating their own nutrition landscapes.

As the cost of food continues upward, 90% of surveyed US adults acknowledge that healthy food has become more expensive in recent years. Nearly seven in ten say these price increases make it more difficult to maintain a healthy diet, with lower-income individuals feeling the pinch most acutely. The survey, conducted among 5,123 adults, captures shifting priorities and the struggle to eat healthy in a world saturated by rising obesity, proliferating food delivery options, and ever-changing dietary advice from social media influencers (pewresearch.org).

A recent Pew Research Center survey paints a clear picture of how rising food prices and evolving lifestyles influence healthy eating in 2025. The findings show that taste, convenience, affordability, and health are all weighing into daily choices. For Thai readers, the study offers valuable parallels as Thailand faces similar nutrition challenges and ongoing public health campaigns.

As food prices rise, 90% of adults surveyed in the United States acknowledge that healthy food has become more expensive. About 70% say price increases make it harder to maintain a healthy diet, with lower-income individuals feeling the squeeze most. The study included 5,123 adults and highlights how affordability, access, and knowledge shape dietary health amid rising obesity, abundant delivery options, and shifting dietary guidance from social media influencers. The research is reported through national institutions and public health experts.

Aspartame, the popular calorie-free artificial sweetener featured in thousands of food and drink products across Thailand and the globe, is under renewed scrutiny after recent research highlighted its potential health risks despite decades of widespread use. While aspartame has long been promoted as a guilt-free alternative to sugar—especially for those managing weight or diabetes—nutrition experts caution that its effects may not be entirely benign, prompting Thai consumers to reconsider their dietary choices in light of emerging evidence.

A long-standing scientific debate has finally been resolved. Researchers have confirmed a “crazy” theory from 1958 about vitamin B1, or thiamine. By stabilizing an extremely reactive carbene intermediate in water, they observed a stable form long thought impossible. The breakthrough, published in Science Advances, signals new possibilities for sustainable chemical manufacturing worldwide, including in Thailand.

The idea dates back to Ronald Breslow at Columbia University, who proposed that vitamin B1 forms a fleeting carbene-like species during essential cellular reactions. Carbenes are notoriously unstable in water, the solvent of life, which kept the theory unproven for decades. Breslow’s concept seemed almost magical to many scientists.

In a scientific breakthrough decades in the making, researchers have finally confirmed a “crazy” theory dating back to 1958 involving vitamin B1, or thiamine. By successfully stabilizing an extremely reactive molecule known as a carbene in water—something scientists long believed to be impossible—this team has not only resolved a long-standing biochemical debate but also unlocked new possibilities for sustainable chemical manufacturing around the world, including Thailand. Their results, published in Science Advances on April 11, 2025, have sparked fresh excitement in both academic and industrial laboratories worldwide (SciTechDaily).

Aspartame, a widely used artificial sweetener in thousands of foods and drinks, is once again under scrutiny. While it has long been promoted as a sugar substitute that helps with weight control and blood sugar management, new analyses are raising questions about its long-term safety. Thai consumers are increasingly weighing the benefits against emerging concerns as part of a broader move toward healthier choices.

Leading researchers have summarized recent findings in an expert review by The Conversation. Aspartame, developed in 1965, is more than 180–200 times sweeter than sugar and contributes virtually no calories, making it attractive for those seeking to cut calories and manage diabetes. In Thailand, as in many countries, diet beverages and sugar-free products have become common, reflecting both public health guidelines and market trends. The World Health Organization and Thailand’s Ministry of Public Health have long recommended limiting added sugars, guiding the shift toward non-nutritive sweeteners and other low-calorie options.

Canned tuna remains a staple for many Thai households thanks to its convenience, affordable protein, and long shelf life. Yet new research and consumer alerts have prompted a closer look at daily consumption, especially for pregnant women, children, and others who are more vulnerable to mercury exposure.

The key concern is mercury, a metal that can accumulate in larger tuna species such as albacore (white tuna). Prolonged intake of mercury is linked to nervous system and cardiovascular impacts. Health authorities in the United States emphasize ongoing monitoring of seafood safety and provide guidance on how much tuna is safe to eat. Consumer Reports recently highlighted spikes in mercury levels in some mass-produced tuna cans, prompting renewed caution for tuna lovers everywhere.

A wave of international research and expert commentary urges caution with vitamin supplements, especially for vitamin B12 and iron. Excessive or unnecessary use may pose health risks rather than deliver expected benefits. The discussion, highlighted by health professionals, has direct relevance for Thai readers amid a booming supplement market and rising health awareness.

Vitamins and minerals are essential, but recent studies show that indiscriminate use can be harmful. In Thailand, convenience stores, pharmacies, and online platforms offer a vast array of brands, often promoting “more is better.” Yet summaries in leading journals indicate that taking supplements without a clear medical need can cause adverse effects, with iron and vitamin B12 frequently cited as substances to watch when overused.

As the cost of groceries rises and quick meal options are in high demand, canned tuna remains a popular staple in the pantries of households across the globe—including Thailand. Lauded for its convenience, protein content, and long shelf life, canned tuna often stars in salads, sandwiches, and school lunchboxes. Yet as new research suggests, the decision to make canned tuna a daily habit deserves a closer look, especially for health-conscious Thais and vulnerable groups like children and pregnant women.

A new wave of international medical research and expert commentary is urging consumers to approach vitamin supplements—such as vitamin B12 and iron—with greater caution, as excessive or unnecessary supplementation may pose health risks rather than provide the expected health benefits. This renewed scrutiny, recently highlighted by a leading health expert on The Economic Times, has direct implications for Thai consumers amid the booming supplement industry and rising health consciousness.

Vitamins and minerals play essential roles in human health, but recent studies show that indiscriminate use, particularly of vitamin B12 and iron, may carry hidden dangers. In Thailand, where convenience stores, pharmacies, and online marketplaces are flooded with a dazzling array of supplement brands, the prevailing belief that “more is better” has fueled a multi-billion-baht industry. However, according to recent research summaries published in journals like the New England Journal of Medicine and JAMA, the blanket use of supplements without clear medical need may contribute to adverse effects, with iron and vitamin B12 topping the list of potentially problematic substances when overused.

A recent analysis by leading nutrition researchers has sounded an alarm about a growing deficiency of omega-3 fatty acids worldwide, a shift that experts warn may have broad and potentially lasting consequences for public health. With more than 85% of surveyed populations now failing to meet recommended omega-3 intake, researchers say modern diets, environmental change, and ocean pollution have dramatically undermined access to this essential nutrient (Earth.com).

Omega-3 fatty acids—long heralded for their roles in heart, brain, and eye health—are a cornerstone of a balanced human diet. For Thai readers, who live in a nation rich in seafood traditions, these findings raise new questions about the sustainability of trusted food sources and the best strategies to promote lifelong wellbeing. Nutrition scientists highlight omega-3 as crucial to preventing cardiovascular disease, supporting memory and mood, and facilitating the healthy function of cells throughout the body. According to a research scientist with Case Western Reserve University’s Department of Population and Quantitative Health Sciences, “This has serious and widespread health implications.”

A widespread shortfall in dietary fiber is linked to digestive issues, heart health risks, and unstable blood sugar. Nutritionists say small, everyday food swaps can boost fiber without sacrificing taste or convenience. With ultra-processed foods rising and busy schedules cutting into meal prep, a fiber-focused mindset is timely for health-conscious Thai readers.

Data shows many adults in Thailand do not meet the international fiber guideline of 22 to 34 grams per day. Health authorities emphasize that fiber supports digestive health, a balanced gut microbiome, better blood sugar control, and weight management. The reality on the ground is that many meals—rice-based and fiber-light—may fall short, especially in urban settings.

A nationwide lack of dietary fiber is putting millions at risk of digestive issues, poor heart health, and unstable blood sugar—but nutritionists say that simple, everyday food swaps can swiftly boost fiber intake without compromising flavor or convenience. With ultra-processed foods on the rise and busy lifestyles squeezing out healthy meal prep, a new spotlight on fiber is timely for health-conscious readers across Thailand.

Over 95% of Americans reportedly fall short on fiber, a figure likely mirrored in Thailand as dietary patterns globalize and rice-centric, fiber-light meals persist in daily routines (Delish). Fiber is not just for digestive wellness: research links adequate fiber intake to lower risks of heart disease, improved gut microbiome health, better blood sugar regulation, and helpful weight management (CDC, PubMed). For adult Thais, the international recommended daily fiber intake is 22 to 34 grams, but most fall far short, according to local public health officials.

A new analysis highlights a rising global deficiency of omega-3 fatty acids, a trend that could have lasting effects on public health. More than 85% of surveyed populations are not meeting recommended omega-3 intake, with modern diets, environmental change, and ocean pollution constraining access to this essential nutrient. Research by leading nutrition scientists emphasizes the urgency of addressing this gap, especially for countries with strong seafood traditions like Thailand.

Omega-3s are vital for heart, brain, and eye health. For Thai readers, the findings prompt questions about the sustainability of trusted food sources and practical steps to safeguard lifelong wellbeing. Experts note omega-3’s key role in preventing cardiovascular disease, supporting memory and mood, and maintaining healthy cellular function. A senior scientist from Case Western Reserve University describes the implications as broad and significant.

A growing number of nutritionists warn that persistent hunger and lingering fatigue may indicate insufficient protein intake. In Thailand, where meals often center on rice, this issue has particular relevance for anyone aiming to stay healthy and energized.

Protein is a key macronutrient essential for building and repairing body tissues, supporting immune function, and regulating metabolism. Nutrition professionals emphasize that proteins are made of amino acids, the building blocks of life. According to research cited by a leading Bangkok nutritionist, protein plays a central role in the structure and function of the body’s cells. Data from respected health organizations reinforces that proteins are vital for maintaining tissues and organs.

Nutrition experts are sounding the alarm about a potentially overlooked dietary issue: not getting enough protein, a problem that can have far-reaching effects on health and wellbeing. According to the latest research and insights from leading registered dietitians, a persistent feeling of hunger and lingering fatigue between meals may be the number one warning sign that you’re falling short on this vital nutrient. In Thailand—where carbohydrate-rich diets, especially those based on rice, are the norm—this finding holds special relevance for anyone keen to maintain optimal health.

New international research suggests creatine supplementation may offer a small boost to muscle mass and strength in older adults who also perform resistance training. The findings are timely for aging societies like Thailand, where preserving independence in later life is a growing concern.

As Thailand’s population ages, families seek safe, effective ways to maintain muscle and mobility. Sarcopenia—the gradual loss of muscle with age—raises the risks of frailty and falls. A practical, evidence-based approach combining exercise with affordable supplements is increasingly prioritized.

A surge of new research is shedding light on whether creatine supplementation can benefit older adults looking to maintain muscle strength and physical function—a subject of growing interest in aging societies like Thailand. While creatine is best known as a staple among young athletes, recent studies suggest its effects extend modestly into older age, provided it’s combined with resistance training.

As Thai society faces the realities of an aging population, many individuals and families are searching for effective, safe interventions to help preserve muscle mass and independence into later life. Age-related muscle loss, or sarcopenia, underpins higher risks of frailty, falls, and reduced quality of life among seniors. Strategies to slow or reverse this decline are urgently needed, making the question of accessible supplements like creatine highly relevant. But what does the latest science say?

A growing trend among fitness enthusiasts and everyday readers in Thailand is using electrolyte powders to “boost” hydration. New analysis from a registered dietitian, reviewed by medical professionals at NBC’s TODAY, suggests that most people do not need these supplements and that excessive intake can pose health risks. The article emphasizes caution and context for Thai readers.

Electrolytes—sodium, potassium, magnesium, and calcium—are essential minerals that regulate hydration, muscle function, and nerve signals. Their importance is clear, especially for high-intensity activity or very hot weather. Yet for many people, especially in Thailand’s warm seasons, supplemental powders may be unnecessary or even risky. Nutrition experts stress that you can meet electrolyte needs through ordinary foods and beverages.
