Mediterranean Diet Side Effects & Benefits

The Mediterranean diet is an eating pattern based on the traditional cuisine of Greece, Italy, Spain, and other countries bordering the Mediterranean Sea.

Plant foods, such as whole grains, vegetables, legumes, fruits, nuts, seeds, herbs, and spices, are the foundation of this diet. Olive oil is also a major source of additional fat.

Meanwhile, fish, seafood, milk, and poultry are among the foods that should be limited in moderation. Red meat and sweet foods should only be eaten occasionally.

  • Weight gain due to consuming more than the recommended amount of fat (such as olive oil and nuts).
  • Low iron levels due to not eating enough meat. If you decide to follow this diet, be sure to include some foods rich in iron or vitamin C, which helps the body absorb iron.
