Eggs

Eggs are a versatile protein and nutrient-dense food consumed regularly across Mediterranean cultures. They are used in breakfasts (shakshuka, Greek spanakopita), baking, pasta, and as a binding agent in vegetable dishes. The Mediterranean approach to eggs is diverse — prepared by poaching, scrambling, hard-boiling, or baking with vegetables and herbs — and does not typically pair eggs with processed meats or high-saturated-fat accompaniments.

Nutritional Profile

Eggs are one of the most nutrient-dense whole foods:

  • High-quality protein: Approximately 6g of protein per large egg, with a complete amino acid profile
  • Choline: Eggs are the richest dietary source of choline, important for neurological function and lipid transport (phosphatidylcholine)
  • B vitamins: B12, riboflavin (B2), and folate — particularly concentrated in the yolk
  • Vitamin D: Eggs contain vitamin D (approximately 40 IU per large egg), primarily in the yolk
  • Minerals: Selenium, iodine, iron, and phosphorus

Cardiovascular Considerations

The relationship between egg consumption and cardiovascular risk has been extensively studied and is nuanced:

  • Dietary cholesterol: A large egg contains approximately 185 mg of cholesterol. For most individuals, dietary cholesterol has a modest effect on plasma LDL-C — the larger determinant is saturated fat intake
  • Replacing processed meats: In the Mediterranean dietary pattern, eggs serve as a protein source that replaces processed and red meats — a beneficial trade-off
  • The Ornish context: The Ornish Lifestyle Heart Trial allowed egg whites (no limit) but excluded yolks as part of its very-low-fat (<10%) vegetarian protocol, reflecting a more restrictive approach than Mediterranean dietary patterns

Mediterranean Preparation

In traditional Mediterranean cooking, eggs are prepared:

  • Shakshuka: Eggs poached in spiced tomato and pepper sauce (North African, adopted in Mediterranean cuisine)
  • Spanakopita: Phyllo pastry with spinach and egg-based filling (Greek)
  • Frittata: Open-faced omelet with vegetables and herbs (Italian)
  • Huevos divorciados: Eggs with salsa and beans (Mexican influence; replaced with Mediterranean herbs and tomato in the wiki context)
