Does poop smell better on plant-based diet? A plant-based diet can lead to better-smelling stool due to reduced sulfur intake, improved digestion, and a healthier gut microbiome. While certain plant foods can still produce odors, they are generally less intense than those from meat-heavy diets. Overall, adopting a plant-based diet supports digestive health and well-being. Additionally, trying a lemon balm recipe for weight loss may further aid digestion and promote gut health.
