Are Onions Hot or Cold?

Published in Food Properties 2 mins read

Onions are considered to have cooling properties, particularly when consumed raw or lightly cooked.

Understanding Onion's Cooling Properties

Based on the provided reference from the Times of India, onions don't generate heat but rather help the body cool down. This isn't about the temperature of the onion itself but its effect on the human body.

Here's a breakdown:

  • Natural Cooling: Onions possess natural cooling qualities that help in reducing body temperature.
  • Raw Consumption: Consuming onions raw, or lightly cooked, maximizes these cooling effects.
  • Key Compounds: The presence of compounds such as quercetin and sulfur compounds contribute to this cooling action.

How Onions Cool You Down

The following explains how the compounds in onions cause this cooling effect:

  • Quercetin: This compound acts as an antioxidant and may contribute to the overall cooling sensation by potentially reducing inflammation and aiding blood circulation.
  • Sulfur Compounds: These compounds aid in detoxification processes, helping regulate body temperature and providing relief from heat.

Practical Examples

Here are some ways to incorporate onions for their cooling benefits:

  • Salads: Add raw onion slices to salads for a fresh, cooling crunch.
  • Sandwiches: Include thin slices of onion in sandwiches and wraps.
  • Raita: Prepare a cooling raita with yogurt, cucumber, and finely chopped onions.
  • Lightly Sautéed: Lightly sauté onions to reduce their pungency while still maintaining some of their cooling properties.
