Research shows that only 7.8% of Moroccan teenagers follow the Mediterranean diet well, with more than half eating poorly according to a study of 386 students. According to Gram Research analysis, girls were significantly less likely than boys to eat Mediterranean foods, with 59.2% of girls having poor diet adherence compared to 44.6% of boys. This shift toward processed foods is concerning because eating habits formed as a teenager typically continue into adulthood, potentially increasing disease risk later in life.
A new study of 386 Moroccan teenagers found that most aren’t following the Mediterranean diet, which emphasizes fruits, vegetables, fish, and olive oil. According to Gram Research analysis, only about 8% of these teens ate in a way that matched Mediterranean diet principles, while over half had poor eating habits. The research also discovered that girls were less likely than boys to follow this healthy eating pattern. Scientists say this shift away from traditional Mediterranean foods toward processed snacks is concerning because eating habits formed as a teenager often continue into adulthood.
Key Statistics
A cross-sectional study of 386 Moroccan school-aged adolescents found that only 7.8% had optimal adherence to the Mediterranean diet, while 53.6% had poor adherence, according to research published in Nutrition and Health in 2026.
Among 386 Moroccan teenagers assessed with the KIDMED index, girls were significantly less likely to follow Mediterranean diet principles, with 59.2% of girls showing poor adherence compared to 44.6% of boys.
The mean KIDMED score for 386 Moroccan adolescents was 4.27 out of a higher possible score, with boys scoring significantly higher at 4.70 compared to girls at 4.00, indicating substantial room for dietary improvement.
A 2026 cross-sectional study of 386 Moroccan teenagers revealed that moderate to optimal Mediterranean diet adherence was more common in boys (55.4%) than girls (40.7%), suggesting gender-based differences in healthy eating patterns.
The Quick Take
- What they studied: Whether Moroccan teenagers were eating foods that match the Mediterranean diet, which is known to be very healthy
- Who participated: 386 school students in Morocco between ages 14 and 18 years old
- Key finding: Only 7.8% of the teenagers ate in a way that matched the Mediterranean diet well. More than half (53.6%) had poor eating habits. Girls were significantly less likely than boys to follow this healthy diet pattern.
- What it means for you: If you’re a teenager or parent, this research suggests that many young people are eating too many processed foods and not enough fresh fruits, vegetables, and fish. Schools and families should work together to make healthy Mediterranean foods more available and teach teens why these foods matter for their health.
The Research Details
Researchers conducted a cross-sectional study, which is like taking a snapshot of a group at one point in time. They surveyed 386 Moroccan teenagers at school and asked them detailed questions about what they ate. The researchers used a special tool called the KIDMED index, which is specifically designed to measure how well young people follow the Mediterranean diet. This tool asks about eating habits like whether teens eat vegetables, fruits, fish, and olive oil, and whether they skip breakfast or eat too many sugary snacks. The researchers also measured each teen’s height, weight, and waist size to understand their overall health.
Using a standardized tool like KIDMED is important because it lets researchers compare results across different countries and studies. This helps scientists understand whether the shift away from Mediterranean eating is happening worldwide or just in certain places. Having a reliable measurement tool also helps schools and health programs know exactly which eating habits need to improve.
This study has several strengths: it used a validated assessment tool designed specifically for teenagers, it measured actual body measurements rather than just asking about weight, and it included a reasonably large sample of 386 students. However, the study only looked at one point in time rather than following students over months or years, so we can’t know if eating habits are getting worse or staying the same. The study was conducted in Morocco, so results may not apply exactly to teenagers in other countries with different food availability and cultural traditions.
What the Results Show
The study found that Mediterranean diet adherence among Moroccan teenagers was quite low overall. Only 7.8% of the 386 teenagers had optimal adherence, meaning they were eating in a way that closely matched Mediterranean diet principles. More than half of the teenagers (53.6%) had poor adherence, suggesting they were eating mostly processed foods and not enough fresh, whole foods. About 38.6% had moderate adherence, meaning they were doing okay but could improve significantly. The average KIDMED score was 4.27 out of a possible higher score, which indicates room for improvement across the entire group.
An important secondary finding was the difference between boys and girls. Girls were significantly more likely to have poor adherence (59.2% of girls versus 44.6% of boys). Boys were more likely to have moderate or optimal adherence. The average KIDMED score for boys was 4.70 compared to 4.00 for girls, a statistically significant difference. This suggests that girls may face different barriers to eating healthy Mediterranean foods, which could include cultural factors, food access, or different eating pressures.
This research fits with other studies showing that young people worldwide are eating less like their grandparents did and more like people in countries with high processed food consumption. The Mediterranean diet has been studied extensively in adults and consistently shown to reduce heart disease, diabetes, and other chronic diseases. This study adds important evidence that teenagers in Morocco are not maintaining these traditional healthy eating patterns, which is concerning because eating habits formed in adolescence tend to continue into adulthood.
The study has several limitations to consider. It only looked at teenagers at one point in time, so we don’t know if eating habits are changing year to year. The study was conducted only in Morocco, so results may not apply to teenagers in other countries. The researchers note that the KIDMED index itself may need updating to better reflect modern Mediterranean diet principles and current dietary guidelines. Additionally, the study didn’t explore why teenagers are moving away from Mediterranean foods, such as whether it’s due to cost, availability, marketing of processed foods, or changing preferences.
The Bottom Line
Based on this research, schools in Morocco and similar regions should implement nutrition education programs that teach teenagers about Mediterranean diet foods and their health benefits. Parents should try to include more fresh fruits, vegetables, whole grains, fish, and olive oil in family meals. Food policies should make these healthy foods more affordable and accessible in schools. However, this is one study in one country, so these recommendations should be adapted to local food systems and cultural preferences. Confidence level: moderate, based on a well-designed cross-sectional study with a reasonable sample size.
Teenagers and their parents should care about this research, especially those in Mediterranean regions or countries with similar food cultures. School administrators, nutritionists, and public health officials should use these findings to design better nutrition programs. Food companies and policymakers should consider how to make healthy Mediterranean foods more appealing and accessible to young people. This research is less directly relevant to teenagers in countries where Mediterranean diet is not part of the traditional food culture, though the general principle of eating whole foods instead of processed foods applies everywhere.
If a teenager starts eating more Mediterranean diet foods today, they might notice improvements in energy levels and how they feel within 2 to 4 weeks. More significant health benefits like better weight management, clearer skin, and improved athletic performance typically appear within 2 to 3 months of consistent healthy eating. The biggest benefits for disease prevention and long-term health develop over years and decades of maintaining these eating habits.
