What Foods Are Highest in Quercetin?

Have you ever wondered what foods are highest in quercetin? If you have, then this article is for you.

In this article, we will list the top 25 foods by quercetin concentration according to the USDA. If you are reading this with an eye towards increasing your food-sourced quercetin levels, bear in mind that the numbers given here are all based on a 100 gram or 100-milliliter serving, not a typical-sized serving. 

Fresh dill may rank much higher than okra or kale, but consuming 100g of dill would be difficult while eating several hundred grams of kale is relatively easy. Taking this into account, let’s dive right in.

1. Capers (Capparis spinosa) 233.84mg/100g

Fresh capers can be difficult to find outside of the Mediterranean regions of Europe. Canned capers are more common in U.S. groceries and have 172.55mg. Unfortunately, canned capers are also sodium bombs that some people should eat with caution.

2. Raw Lovage Leaves (Levisticum officinale) 170.00mg/100g

Lovage leaves are a common culinary herb used in several styles of European cooking and are a wonderful touch added to salads. They taste very similar to celery, but with a touch, more bite, and many people enjoy them in herbal teas.

3. Elderberry Juice Concentrate (Sambucus) 108.16mg/100ml

The use of Elderberry juice in traditional medicine goes back eons. Created by cooking down the toxic berry of the Sambucus vine, elder juice is very dense in antioxidants, minerals, and vitamins. Common ailments it reportedly aids are stomach issues, cold and flu symptoms, and high cholesterol.

4. Raw Dock (Rumex Crispus) 86.20mg/100g

Raw dock has a flavor much like healthy spinach but with a pronounced sour edge. Besides being loaded with quercetin, it is also rich in Vitamins A and C, a host of minerals, and many micronutrients.

5. Radish Leaves (Raphanus raphanistrum) 70.37mg/100g

We usually don’t think of eating radish leaves, but we should. They have a peppery flavor that can be pretty intense, but they can be delightful when mixed with other greens, raw or cooked. Best of all, they are very nutritious and have high concentrations of quercetin.

6. Rocket Greens (Diplotaxis tenuifolia) 66.19mg/100g

Rocket greens have been popular in Asian and Arabic cuisines for centuries. They have a distinctive peppery taste with a sweet-nutty undertone that doesn’t compare to other greens. Rich in nutrients and quercetin, a rocket salad gives a great energy boost when paired with high-protein meals.

7. Fresh Dill (Anethum graveolens) 55.15mg/100g

Dill weed is a culinary staple herb that pairs well with seafood and vegetable dishes. Especially at home with cucumbers, it is the featured ingredient in many pickle recipes and Greek salads. If you are new to working with dill, you should tread lightly, as it can become very dominating when overused.

8. Fresh Cilantro (Coriandrum sativum) 52.9mg/100g

Anyone who loves Mexican-style salsas is familiar with cilantro. What many may not realize, though, is that this magnificent herb is loaded with quercetin, naturally occurring antibiotics, and may help eliminate metals from our systems. 

9. Raw Banana Peppers (Capsicum annuum) 50.63mg/100g

Sweet and mild without the spicy bite that hot chilies possess, banana peppers are lovely in fresh salads, stuffed and baked, or pickled. Great, as a salad topper, banana peppers are rich in vitamins A, C, B6, and active enzymes. 

10. Raw Fennel Leaves (Foeniculum) 48.80mg/100g

The most common use of juniper is in the flavoring of Gin.

12. Mexican Oregano (Lippia graveolens) 42mg/100g

Mexican oregano has a more robust flavor than regular oregano but less bitterness and more citrus and floral tones. It is most at home in salsas, burritos, beans, soups, tacos, and enchilada sauces but usable as a substitute in any dish that calls for oregano. 

13. Carob Flour (Ceratonia siliqua) 38.78mg/100g

The carob tree is a flowering evergreen native to the Mediterranean. Its bean pods are gathered and opened, and the pulp inside once dried and ground into a flour-like powder.

Red bulb spring onions are the juvenile form of the red onions listed above.

Watercress is an aquatic cabbage and one of the oldest known leaf vegetables that we consume. Noted for its piquant flavor, watercress is widely eaten in Europe, often alone in sandwiches with mayo-type dressings.
