A narrative review in Applied Sciences examines how long working hours, food costs and reliance on convenient ultra-processed products can make the Mediterranean diet and lifestyle difficult to maintain. It points to food-environment changes and practical programs as possible ways to improve adherence, but its literature selection was not systematic, so the findings do not establish that modern lifestyles alone caused changes in health outcomes.
A narrative review published in Applied Sciences examines how long working hours, rising food costs and convenient ultra-processed meals can make the Mediterranean diet and its broader lifestyle harder to maintain. The researchers describe possible ways to adapt food environments and everyday routines, while noting that their review was not based on a systematic screening process.
The review was conducted by researchers affiliated with institutions in Portugal and Spain. It considers the Mediterranean diet as a pattern centered on vegetables, fruits, olive oil, legumes, nuts and whole grains, with more modest amounts of fish, dairy and eggs and limited red meat. The authors distinguish traditional wine consumption as a cultural practice, not a health recommendation.
To gather material, the team searched PubMed, Web of Science, ScienceDirect and Google Scholar between October 2024 and December 2025. Its final reference list included 116 sources, spanning journal articles, book chapters and online resources. The review covered dietary adherence, physical activity, communal meals, food environments and approaches to making healthier choices more accessible.
The authors report that time pressure, lower physical activity and convenience-focused food supplies are among the barriers to maintaining the traditional pattern. Their review also describes lower adherence among groups including urban residents, people with lower incomes, people under high stress, smokers and those with low physical activity. These are patterns reported in the literature the team reviewed, not proof that any one factor causes lower adherence.
How Food Environments Shape Adherence
The review’s central point is that following a diet is not only an individual choice. Time, affordability and access can shape what people eat, while readily available ready-to-eat products may be easier to fit around work and daily responsibilities. The authors argue that efforts to encourage Mediterranean-style eating may need to address those conditions, rather than relying only on nutrition information.
The review describes several interventions that reported improved adherence. In one workplace study, 96 male workers who ate Mediterranean-style canteen lunches for 12 months increased their diet score from 4.8 to 7.4; the share with metabolic syndrome fell from 24% to 15.6%. A separate trial with 485 U.S. firefighters combined supermarket discounts, free samples, online education and chef demonstrations, and researchers reported a 10% improvement in adherence. A school program in Cyprus involving food tasting and cooking lessons also improved students’ nutrition knowledge and diet-quality scores.
These examples suggest that workplaces, schools and retailers could help make healthier choices more practical. They do not show that every intervention will work in every population, or that the reported changes were caused by any single component of a program.

A Traditional Pattern Under Pressure
The Mediterranean diet is often studied as both a way of eating and part of a wider lifestyle. The review includes communal meals and everyday movement alongside food choices, and notes that the pattern associated with mid-20th-century Mediterranean populations cannot be reduced to a list of ingredients. The authors say those populations were reported to have longer life expectancy and lower rates of some chronic illnesses, but other features of life may also have contributed.
The review places current concerns against shifts in eating habits since the 1960s, describing declining adherence, particularly among younger, urban and lower-income groups. It cites global figures indicating that roughly 2.5 billion adults were living with overweight in 2022 and that about 3 billion people could not afford a healthy diet. Those figures provide context for nutrition challenges; they do not, by themselves, show that reduced Mediterranean-diet adherence caused those outcomes.
Cost comparisons cited in the review put ultra-processed foods at $0.55 per 100 calories, compared with $1.45 for unprocessed foods. The article does not establish that this price difference applies uniformly across places or products. It illustrates the affordability concern the authors raise, rather than serving as a universal price estimate.
“The traditional Mediterranean way of eating is becoming increasingly difficult to maintain under contemporary urban living conditions.”

Limits of the Review Evidence
The paper is a narrative review, not a systematic review or a new population trial. The authors did not use predefined exclusion criteria or a systematic screening protocol, and they acknowledge that this leaves room for selection bias. The findings therefore summarize a selected body of research and should not be read as a definitive estimate of how strongly each modern-life barrier affects adherence.
The review also discusses changes in noncommunicable-disease mortality in several Mediterranean countries from 1960 to 2020. The authors caution that those changes could reflect population aging and other risk factors, not dietary changes alone. It remains unclear from this review how much of the reported health trends can be attributed specifically to diet, or which proposed interventions would have lasting effects at larger scale.
Testing Practical Changes at Scale
The review points toward food-environment measures such as workplace and school programs, more accessible healthy meals, and product development that makes convenient options more nutritious. The authors also discuss using agri-food byproducts and encouraging physical activity, though the review does not establish which approach should take priority.
The next evidence needed is larger, well-designed studies that track adherence and health outcomes over time, compare intervention components, and account for differences in cost and access. Until then, the review offers a map of reported barriers and possible responses, rather than a single proven solution to the gap between traditional eating patterns and modern routines.
Key Questions
What is the actual development reported?
Researchers published a narrative review in Applied Sciences examining why modern urban routines can make the Mediterranean diet and lifestyle harder to maintain, and what food-environment strategies might help.
What barriers does the review identify?
The review discusses long working hours, limited time to cook, food costs, convenience-focused food supplies and reduced physical activity. It also reports lower adherence in some groups, including urban residents and people with lower incomes.
Does the review prove that diet changes caused rising disease rates?
No. The authors caution that changes in noncommunicable-disease mortality may also reflect population aging and other risk factors. The review does not establish that dietary changes alone caused those trends.
What kinds of interventions showed promise?
The paper describes studies involving Mediterranean-style workplace lunches, supermarket discounts and education, and school cooking and tasting activities. The reported results are tied to those particular programs and do not guarantee similar effects elsewhere.
How strong is the evidence in this paper?
The paper is a narrative review of 116 sources. Because it did not use predefined exclusion criteria or a systematic screening protocol, its conclusions may be affected by selection bias and do not carry the same weight as a systematic review.
