The saying, "You are what you eat," highlights the crucial link between diet and health. Consuming nutritious food is essential for maintaining health and fitness, providing the body with the necessary nutrients to function optimally. While the detrimental effects of nutrient deficiencies have long been recognized, recent studies have revealed more intricate connections between dietary patterns and health outcomes. For example, excessive consumption of refined sugars has been linked to increased risks of cardiovascular diseases, depression, type 2 diabetes, and even cancer. This raises the question: are there dietary patterns that can protect our health, particularly in children?
The Mediterranean diet, inspired by the traditional eating habits of people in countries bordering the Mediterranean Sea, emphasizes the consumption of fruits, vegetables, whole grains, legumes, nuts, and olive oil, with moderate amounts of fish and poultry, and limited intake of red meat and sweets. This dietary pattern has been associated with numerous health benefits, including reduced risks of heart disease and diabetes.
What is the Mediterranean Diet?
The Mediterranean diet isn't a strict set of rules but rather a framework for healthy eating based on the traditional cuisines of countries bordering the Mediterranean Sea. There's no single definition, but the core principles remain consistent.
Instead of prescribing strict food guidelines, the Mediterranean diet emphasizes healthy foods like fruits, vegetables, whole grains, nuts, and fish, combined with an active lifestyle, and enjoying time with family and friends.
Key Components of the Mediterranean Diet
The Mediterranean diet prioritizes plant-based foods. The foundation of the Mediterranean diet is plant foods. Moderate amounts of dairy, poultry, and eggs are part of the Mediterranean diet, as is seafood. Here's a breakdown of the key components:

- Abundant Fruits and Vegetables: Aim for 2 to 3 servings of fruit and four or more servings of vegetables each day. One serving of fruit equals a medium piece of whole fruit or one cup of chopped fruit.
- Whole Grains: Choose whole-grain bread, cereal, and pasta. You can also try other whole grains, such as bulgur, barley, and farro. If you eat about 2,000 calories a day, aim to have at least 3 ounces of whole grains. You can get 1 ounce from a slice of bread, a cup of ready-made cereal, or half a cup of cooked rice or pasta.
- Healthy Fats: Unsaturated fats are a strength of the Mediterranean diet. Olive oil and nuts are the main sources of fat in the Mediterranean diet. They provide unsaturated fat. Replacing saturated fats with unsaturated fats may help lower the risk of heart disease. For example, you could replace butter with olive, canola, or safflower or sunflower oil in cooking or at the table.
- Seafood: Fish also are a key part of the Mediterranean diet. These are known as fatty fish. Omega-3s are unsaturated fats that may lower immune system action in the body known as inflammation. They also may help reduce blood fats called triglycerides, and they affect blood clotting. Lean fish and shellfish also are included in the Mediterranean diet. Shellfish include shrimp, crab, clams, and scallops. Choose fish that are low in mercury. Eat fish or shellfish 2 to 3 times a week. One serving of fish is around 3 to 5 ounces for adults. That's about the size of a deck of cards. Fresh or water-packed tuna, salmon, trout, mackerel, and herring are healthy choices.
- Nuts and Seeds: Each week, aim to eat four servings of raw, unsalted nuts.
- Dairy in Moderation: Some good choices are skim or 1% milk, low-fat cottage cheese, and low-fat Greek or plain yogurt. Limit how much cheese you eat. One serving is about the size of four dice. And cut back on higher fat dairy.
- Limited Red Meat and Processed Foods: Reduce red and processed meat. Eat more fish, poultry, or beans instead. If you eat meat, make sure it's lean and keep portions small.
- Flavor with Spices: The Mediterranean diet emphasizes flavoring food with spices - instead of salt.
Benefits of the Mediterranean Diet for Kids
The Mediterranean diet offers numerous potential benefits for children, focusing on essential nutrients and healthy habits. Following the Mediterranean diet allows families to focus on what they're likely missing in their meals, including fruits, vegetables and seafood.
- Prioritizes Fruits and Vegetables: The Mediterranean diet focuses on fruits and vegetables first, ensuring servings include the important vitamins and minerals needed to maintain a strong and healthy body. The nutrients in fruits and vegetables are essential to our health and growth, particularly for children. If we're missing one of these key building blocks, the body struggles. It can be harder to pay attention in school, our sleep can be affected and we may feel more irritable and sluggish.
- Emphasizes Whole Grains: Whole grains are an excellent source of dietary fiber, which offers many benefits, including keeping kids "regular," helping you feel full longer, helping with maintaining a healthy weight, and reducing blood cholesterol and the risk of heart disease.
- Incorporates Healthy Fats: Healthy fats, like unsaturated fats and omega-3 fatty acids, help absorb vitamins and fats children need to grow and thrive. Good sources of healthy fats include avocados, chia seeds, eggs, fatty fish (such as salmon), flaxseed, nuts, olive oil, and peanut butter.
- Encourages Seafood Consumption: Fish is a high-quality protein with many important nutrients, like vitamin D, iodine, and omega-3 fatty acids. It's also thought that seafood can improve heart health, brain health, and vision.
- Includes Dairy as a Good Source of Calcium: Dairy is important for a child's growing body, providing the calcium their body needs.
- Promotes Flavorful Food with Spices: The Mediterranean diet emphasizes flavoring food with spices - instead of salt.
- Fosters Family Meals: Mealtimes are a social activity in the Mediterranean, an important part of the lifestyle. Eating together strengthens family bonds and allows you to model healthy eating habits for your children.
Potential Impact on Mental Health
Childhood and adolescence are critical periods in the development of mental illness. Anxiety disorders are the most common mental health issue among children, followed by behavior disorders, mood disorders, and substance use disorders. Girls generally tend to have higher rates of mood and anxiety disorders, while boys are more susceptible to behavior disorders. Drug use disorders are equally common among girls and boys.
Several studies have explored the relationship between the Mediterranean diet and mental health in children and adolescents. One systematic review examined 13 studies including 3058 children between 8 and 16 years of age. The studies used different ways to assess adherence to the Mediterranean diet, but most of them used the Mediterranean Diet Quality Index, a 16-item questionnaire.
- ADHD: 4 of the 13 studies examined the links between adherence to the Mediterranean diet and attention-deficit/hyperactivity disorder (ADHD).
- Impulsivity: Two studies examined the links between adherence to the Mediterranean diet and impulsivity. 1 of them reported that participants with higher impulsivity tended to have low adherence to a Mediterranean diet, while the other did not find this link.
- Depressive Symptoms: Five studies examined the links between the Mediterranean diet and depressive symptoms. Of these, four found that participants with depressive symptoms showed much lower adherence to the Mediterranean diet.
- Anxiety: Four studies examined the association between the Mediterranean diet and anxiety. 2 of these studies found participants highly adhering to the Mediterranean diet to have fewer anxiety symptoms.
It's important to note that it remains insufficiently clear whether it is the Mediterranean diet that reduces the risks of developing mental health issues or the absence of mental health issues that leads to higher adherence to the Mediterranean diet.
Adapting the Mediterranean Diet for Kids
The Mediterranean diet is generally considered safe for kids to follow, but it's important to introduce it in a positive and sustainable way.

- Focus on Lifestyle, Not Diet: Avoid calling it a "diet." Instead, call it a lifestyle and invite the entire family to join in. Make the experience positive and fun.
- Be Consistent: It can take 15 times or more for a child to be exposed to a new food before they try it. Keep going and don't give up on picky eaters.
- Get Active Together: Find fun physical activities to do together, like taking a walk or having a dance party.
- Go Slowly: Introduce one new change at a time instead of overhauling all eating habits.
- Involve Your Child: Go to the grocery store together and prepare meals together.
Kid-Friendly Mediterranean Snack Recipes
When parents are ready to introduce the Mediterranean lifestyle to kids, here are a few simple snack ideas:
- Cheese with a piece of fruit
- Fruit with low-fat yogurt
- Nuts
- Vegetables with hummus
- 100% whole wheat bread with peanut butter
Potential Risks and Considerations
While the Mediterranean diet is generally considered safe and beneficial, there are a few potential risks and considerations to keep in mind:
- Allergies: Nuts are a staple in the Mediterranean diet, but they are also a common allergen. Be mindful of any allergies your child may have and adjust the diet accordingly.
- Mercury Levels in Fish: Children and people who are pregnant or breastfeeding may want to limit certain types of fish due to mercury levels. Choose fish that are low in mercury.
- Individual Needs: Not every child needs to adopt a Mediterranean diet, but it is important to increase “real foods” in children’s diets and decrease highly processed foods that have added sugars and sodium. It is always important to keep in mind a child’s preferences and to incorporate cultural traditions into any guidance around food choices.
