It originated in China over 1200 years ago, and its fragrance was believed to drive evil spirits away. This exotic fruit has a strong tangy flavor and aroma. It contains antioxidants that may improve circulation, fight cancer, and reduce inflammation. This article explores the health benefits of yuzu fruit, how to eat it, and possible side effects.

What Is Yuzu Fruit?
Yuzu fruit looks like a small grapefruit (diameter 2-3 inches) with thick yellow, uneven skin. The fruit is extremely aromatic and sourer than other citrus fruits can be yellow or green based on its degree of ripeness. This fruit is highly nutritious and has fewer calories.
Kristin Gillespie, RD, says, “Yuzu fruit contains only 20 calories per fruit, and nutrients like fiber, sodium, magnesium, manganese, and vitamin C.” Yuzu (also called Yuza) is rich in antioxidants and carotenoids, flavonoids, and limonoids and has several health benefits (1), (2).
Health Benefits Of Yuzu Fruit
1. May Prevent Cardiovascular Issues
Yuzu has anti-platelet (inhibits blood clot in the vessels) properties and reduces the risk of stroke and ischemic heart diseases (conditions caused by narrowing of arteries) (3). Studies have found that the methanolic extract of yuzu has flavonoids like hesperidin and naringin, which could inhibit platelet aggregation (4), (5), (6). This can prevent blood clotting and reduce blood vessel inflammation to improve heart health.
In addition, yuzu peel may help prevent hypercholesterolemia (high blood cholesterol levels) (7). The flavonoid hesperidin has cardioprotective properties and may prevent heart failure (8). However, more research is needed to understand the cardioprotective benefits of yuzu.
2. May Fight Against Cancer
The yuzu fruit is packed with antioxidants. The carotenoid compounds and vitamin C in yuzu may reduce cancer risk (2), (9), (10), (11). A review published in Nutrients suggests that citrus fruits intake can suppress the gene expression in many degenerative diseases like cancer. Consuming citrus fruit may reduce the risk of esophageal cancer by 37% (12), (13).
A study conducted by the Cheju National University College of Medicine, Korea, has found that a high intake of citrus fruits protects against stomach cancer. They can also reduce pancreatic and breast cancer risk (14), (15), (16).
3. Supports Brain Health
In addition, citrus flavonoids play a key role in preventing and treating neurodegenerative diseases (ND) (20). A study conducted by the University of Reading, United Kingdom, found that daily consumption of flavanone-rich foods for eight weeks improved cognitive function in older adults (21).
4. Reduces Inflammation
Yuzu peel contains limonene, an anti-inflammatory compound that may help treat bronchial asthma (22). It also has free radical scavenging properties and may prevent cell damage (23). The antioxidant and anti-inflammatory properties of yuzu peel extract can inhibit colitis (inflammatory reaction in the colon) (24). The main flavonoid of yuzu fruit, hesperidin, also possesses anti-inflammatory and antioxidant effects that help treat neurodegenerative diseases (25).
5. Improves Mood
The fragrance of yuzu fruit has similar aromatherapeutic benefits as the lavender scent. Studies confirmed that yuzu fragrance has aromatherapeutic benefits and may decrease anxiety and negative emotions and relaxes the mind (26), (27).
6. Enhances Skin Health
The ethanolic extracts of yuzu peel inhibit elastase (an enzyme that degrades elastin) activity and prevent skin aging (28). The flavonoids and other phenolic compounds in the peel extract promote procollagen synthesis and decrease melanin content to brighten the skin (29).
7. May Prevent Gout
Yuzu peel extract can be used as an anti-gout (anti-hyperuricemic) agent (28). However, further studies are required to prove this effect.
8. May Regulate Sugar Levels
A study on mice fed with a high-fat diet found that ethanol extract of yuzu peel had anti-diabetic effects and might help regulate blood sugar levels (30).
9. May Improve Bone Health
The flavanones in the ethanol extract of yuzu peel and its flavanones promote the development of osteoclasts, a type of bone cells that help repair and maintain bones. Researchers concluded that it could be a basis for developing new therapies for osteoporosis (31).
Yuzu is used as a flavoring agent in different cuisines for its excellent lemony aroma. Since it is super tart and sour, you cannot eat it as it is. Here are some tips to include yuzu in your diet.
How To Eat And Use Yuzu Fruit
You can use it as a replacement for lemons. Yuzu juice and zest are best for adding a refreshing lemony flavor to desserts, baked goods, and condiments. You can add yuzu juice to ceviche or use it as salad dressings and seafood marinades.
In East Asian cuisine, yuzu fruit juice, peel, and seeds are used as flavoring agents for seasonings, sauces, marmalades, lemonade, and ice creams.
Yuzu essential oil is also used in perfumes, lotions, and soaps.
Note: Do not ingest essential oils or use them undiluted.
Yuzu fruit juice is often used to prepare wine, cocktails, and other liquors. You can also buy yuzu juice for culinary use. However, ensure to read the label to check for the amount of added sugar. If possible, buy pure yuzu juice.
