Exploring Fisetin in Onions and Cucumbers

Fisetin, a flavonoid with potent antioxidant properties, is not just limited to strawberries. It can also be found in smaller amounts in onions and cucumbers, making these everyday vegetables a secret source of this beneficial compound.

Fisetin in Onions:

Onions, a staple in many cuisines around the world, contain a variety of bioactive compounds, including fisetin. This flavonoid contributes to the antioxidant capacity of onions, which may help combat oxidative stress in the body. Studies have shown that fisetin in onions could have potential health benefits, such as anti-inflammatory and neuroprotective properties.

Interestingly, onions also contain quercetin, another flavonoid that shares similar antioxidant properties with fisetin. Together, these compounds make onions a powerful addition to a healthy diet.

Fisetin in Cucumbers:

Cucumbers, known for their high water content and refreshing crunch, also provide a source of fisetin. While the levels of fisetin in cucumbers may not be as high as in strawberries, they still contribute to the overall nutritional profile of this versatile vegetable.

In addition to fisetin, cucumbers are packed with nutrients like vitamin K, potassium, and various antioxidants. This combination makes cucumbers a hydrating snack that not only refreshes but also supports overall health and well-being.

Misconceptions about Fisetin Sources

1. Citrus fruits

While citrus fruits are packed with Vitamin C and other antioxidants, they do not contain significant amounts of fisetin. Citrus fruits like oranges, lemons, and grapefruits are renowned for their immune-boosting properties, but when it comes to fisetin, you won’t find much here.

2. Nuts and seeds

Nuts and seeds are fantastic sources of healthy fats, proteins, and various nutrients, but fisetin isn’t one of them. Almonds, walnuts, chia seeds, and flaxseeds may fuel your body with essential nutrients, but they aren’t the go-to choices for fisetin content.

3. Seafood

Seafood lovers, hold on to your hats! While seafood like salmon, tuna, and shrimp are prized for their omega-3 fatty acids and protein content, they do not harbor significant amounts of fisetin. The ocean may be vast and bountiful, but fisetin won’t be swimming your way in your favorite seafood platters.


In conclusion, the hidden gems of fisetin can be found not only in strawberries but also in the humble kitchen staples of onions and cucumbers. These potent sources add a sprinkle of health benefits to your diet.

Next time you’re slicing up these veggies for your salad or stir-fry, remember that you’re not just adding flavor and crunch, but also a dash of fisetin goodness.
