Pickled Red Onions – A Great Source of Quercetin!

ByKatarina Meister, ND September 4, 2023

Red onions are a great source of Quercetin!

Quercetin is a flavonoid found in capers, peppers, and onions. Quercetin is a potent antioxidant with anti-histamine, anti-inflammatory, and anti-viral properties. Quercetin can help to heal a leaky gut (intestinal permeability), reduce menstrual cramps, and support autoimmune disorders (rheumatoid arthritis, inflammatory bowel disease, etc).

The skins and the outermost rings of red onions contain the highest concentration of quercetin. When you make a stir-fry or soup include the skins of red onion and then discard at the end. This will fortify your meal with quercetin from the skins (without having to eat them!).

These pickled red onions are good on everything-  Tacos, sandwiches, salads, or avocado toast!
