Eat Flexitarian Day is observed worldwide every second Monday of June. It was launched in 2022 by Planterra Foods and its food brand OZO to celebrate flexitarians and promote a lifestyle that emphasizes a plant-based diet with moderate consumption of meat and animal products. The day encourages individuals to adopt flexitarianism, which allows for flexibility in meat consumption, and suggests starting with meat-free days. Typical customs include gradually reducing meat intake and incorporating more plant-based foods into one's diet. Although Planterra Foods ceased operations shortly after the inaugural celebration, the holiday continues to thrive. Flexitarianism can be adopted for various reasons, including health, environmental concerns, and animal welfare.
