Mediterranean Magic: Could Olive Oil and Avocados Boost Baby-Making Chances?

The Mediterranean diet has been praised for its numerous health benefits, including reducing the risks of heart disease and promoting overall well-being. But did you know this popular diet can also be an ally for women seeking to conceive through in vivo fertilization? A pilot study suggests that consuming a diet high in monounsaturated fat — typically found in avocados, olive oil, peanuts, almonds, and cashews — can significantly increase the chances of conceiving for women undergoing fertility treatment.

The Role of Monounsaturated Fats in Fertility

Monounsaturated fats are a type of healthy fat found primarily in plant-based foods. These fats have been shown to improve cardiovascular health, reduce inflammation, and support stable blood sugar levels. The effects of monounsaturated fats on fertility have not been as widely studied, but recent findings indicate that they may play a crucial role in improving the chances of conception.

Researchers at the Harvard School of Public Health found that women who consumed the highest amount of monounsaturated fat (25 percent of their total calorie intake) had up to three times the chance of giving birth through in vivo fertilization compared to those who consumed the least (9 percent of their total calories). While the study’s sample size was small and the findings need replication to confirm results, this promising evidence suggests a strong link between the Mediterranean diet and fertility.

Components of a Mediterranean Diet

The Mediterranean diet emphasizes the consumption of nutrient-rich foods, including fresh fruits and vegetables, whole grains, lean proteins, and healthy fats, while minimizing the intake of processed and sugary foods. In addition to monounsaturated fats, the Mediterranean diet also provides essential nutrients that support fertility, such as high-quality protein from fish and legumes; antioxidants from fruits, vegetables, and nuts; and omega-3 fatty acids from fish, nuts, and seeds.

To adopt the Mediterranean diet and improve your fertility, consider incorporating the following food groups into your daily meals:

  • Fruits and vegetables: Aim to consume a variety of colorful, nutrient-dense produce. This will provide an abundance of vitamins, minerals, and antioxidants that support a healthy reproductive system.
  • Whole grains: Choose whole-grain options such as brown rice, quinoa, whole wheat pasta, and whole-grain bread instead of refined grains. Whole grains provide valuable nutrients and fiber to support digestion and blood sugar balance.
  • Lean proteins: Opt for fish, poultry, legumes, nuts, and seeds as your primary protein sources. These foods provide the essential amino acids your body needs for proper hormonal function and cell growth.
  • Healthy fats: Emphasize foods rich in monounsaturated fats, like avocados, olive oil, peanuts, almonds, and cashews. These fats can help improve fertility and overall health.
  • Omega-3 fatty acids: Add omega-3 rich foods such as fatty fish, walnuts, chia seeds, and flaxseeds to your diet. Omega-3 fatty acids support reproductive health by reducing inflammation and promoting hormonal balance.
  • Dairy: Consume moderate amounts of dairy products such as yogurt, cheese, and milk. Some studies suggest that full-fat dairy products, in moderation, may support fertility the National Institutes of Health .
  • Minimize processed and sugary foods: Limit your intake of processed foods and beverages high in added sugars, which may negatively impact fertility and overall health.

Potential Limitations of the Study

As mentioned earlier, the pilot study’s findings linking the Mediterranean diet and fertility success through in vivo fertilization require further investigation. It’s essential to recognize that these findings may not apply to all women seeking to conceive, as each individual’s fertility is influenced by various factors, including age, weight, medical conditions, and lifestyle habits. Moreover, the study solely focuses on monounsaturated fat intake, and more research is needed to determine the possible effects of the other components of the Mediterranean diet on fertility.

Before making any significant dietary changes to boost your fertility, it’s crucial to consult with a healthcare professional, such as a doctor or a registered dietitian nutritionist, who can provide personalized guidance, taking into account your unique medical history and nutritional needs.


The Mediterranean diet’s potential to increase fertility through in vivo fertilization is a promising development for those seeking conception through fertility treatments. By emphasizing the intake of foods rich in monounsaturated fats, nutrient-dense fruits and vegetables, lean proteins, whole grains, and omega-3 fatty acids, the Mediterranean diet may significantly enhance fertility and promote overall health and well-being. While more research is necessary to confirm these results, adopting a Mediterranean-style diet can be a beneficial step towards supporting reproductive health and achieving a successful pregnancy.
