What is Leek?

Leeks are a member of the Allium family, which also includes onions, garlic, and shallots. They have a mild, sweet flavor and are used in a variety of dishes such as soups, stews, and salads. The plant consists of a bundle of leaf sheaths, sometimes mistakenly called a stem or stalk. While leeks are generally nutritious, containing vitamin K, vitamin C, and manganese, they also contain varying levels of FODMAPs depending on the part of the plant consumed.

Why People Avoid Leek

People on a low-FODMAP diet may avoid leeks because the bulb portion of the leek is high in FODMAPs, which can cause digestive discomfort in sensitive individuals. The leaves, however, are considered low to moderate in FODMAPs and may be consumed in small quantities without adverse effects. When food labels do not specify which part of the leek is used, it is often safer for individuals on a low-FODMAP diet to avoid the product.
