Remarkably, purslane seeds contain up to 5-7 times more ALA than spinach, making them an excellent addition to a vegetarian or plant-based diet. Including purslane seeds in your meals can help you reap the benefits of omega-3 fatty acids, which are known to support heart health, reduce inflammation, and promote overall well-being.
Antioxidants and Anti-Inflammatory Compounds
Purslane is packed with a variety of antioxidants and anti-inflammatory compounds that offer numerous health benefits. Some of the key compounds include:
-
Flavonoids: Plant compounds with potent antioxidant and anti-inflammatory properties.
-
Phenolic acids: Antioxidants that have been shown to reduce inflammation.
-
Polysaccharides: Complex carbohydrates that can modulate the immune system.
-
Cerebrosides: Lipids that have demonstrated anti-inflammatory effects.
These compounds work together to reduce inflammation, improve cardiovascular health, and support immune function. By incorporating purslane into your diet, you can take advantage of these powerful health benefits.

Cons of Purslane
Purslane contains oxalates, which may contribute to kidney stone formation in susceptible individuals. Individuals with nonalcoholic fatty liver disease should consult their doctor before consuming purslane due to mixed research results. It may absorb contaminants if grown in polluted areas, making it important to harvest from clean, organic sources. Some people may experience mild digestive discomfort if they are not used to high-fiber foods. While purslane is nutritious, it is not a significant source of protein, so it should be paired with protein-rich foods for balanced nutrition.
