Lunar Vegetarian Days: A Tradition Older Than Any Modern Trend

While the world is 'discovering' plant-based eating as a new trend, Vietnamese people have been systematically practicing vegetarianism since Buddhism entered Vietnam around the 2nd century. This is the cultural foundation Veggie Saigon is built on.

Ăn Chay Kỳ — History

Periodic vegetarian eating (ăn chay kỳ) originates from the Buddhist concept of 'purification' on spiritually significant days. The 1st and 15th of the lunar calendar are days when Buddha and Bodhisattvas are believed to be 'on patrol'. Eating vegetarian on these days is an act of merit-making, precept-keeping, and reverence.

Scale of Practice

An estimated 12–15 million Vietnamese practice periodic vegetarianism at least 2 days per month. In Da Nang alone, with its large Buddhist community, the number eating vegetarian on lunar days may reach 150,000–200,000 people. This is a real, consistent market.

From Temple Kitchen to Restaurant

Traditional Vietnamese vegan cuisine was developed in temple kitchens — where nuns and Buddhists cooked for merit. The techniques for recreating meat flavors from plants (using jackfruit, straw mushrooms, seitan, tofu) are genuine culinary heritage, not modern technology. Veggie Saigon learns from this tradition and brings it to a modern restaurant environment.

Vegetarianism in Vietnam did not start from nutrition books or social movements. It started from the heart — and that is the most durable foundation.
