Why are certain vegetables like mushrooms and red lentils avoided by some Hindu communities?

Some Hindu communities avoid mushrooms and certain lentils based on old beliefs about food and spiritual purity. These rules come from different traditions and vary widely by sect and region.

What different traditions say

Mushrooms are treated differently across Hindu thought. In Ayurveda, mushrooms are sometimes classed as tamasic, meaning they are believed to bring heaviness, dullness, and lack of clarity. Some Vaishnava communities avoid mushrooms because they grow underground or from decay, which is seen as impure. Certain strict communities, like some branches of ISKCON, follow detailed dietary codes that exclude mushrooms and other fungal foods. Red lentils are avoided in some households for similar reasons—they are seen as heating or as lacking the purity of other foods. These rules are not universal. Many Hindu families eat mushrooms and red lentils without concern. The rules depend on which sect or spiritual path a family follows, and on regional custom.

Where these ideas come from

Old texts like the Manusmriti mention foods to avoid, though the exact reasons and which foods matter have been read differently over time and place. The idea that certain foods affect the mind and spirit comes from Ayurvedic thought about the three qualities—sattvic (pure and light), rajasic (active and stimulating), and tamasic (heavy and dull). Mushrooms and underground foods fit into tamasic ideas because they grow in darkness or decay. These beliefs were shaped by the spiritual goals of different communities—some aimed at clarity and devotion, others at health and balance.

In everyday life today

In practice, these rules are kept by some communities and not by others. Strict Vaishnava households and spiritual communities often follow them closely. Many Hindu families, especially in cities and abroad, eat mushrooms and red lentils freely. The choice often depends on family tradition, the sect or guru a person follows, and how strictly they keep dietary rules. Some people avoid them at home but eat them outside. Others see them as fine. There is no single Hindu rule about this—it is a matter of community and personal choice.
