Health Benefits of Yuzu

Yuzu (Citrus junos) is a remarkable little citrus fruit with a global presence, cultivated in regions as diverse as China, Japan, Australia, and Korea. Its distinctive appearance features bumpy, yellow skin, encasing a flesh that’s highly acidic and wonderfully sour.

Within the realm of traditional Chinese medicine (TCM), yuzu serves as a cherished natural remedy, deployed to address a spectrum of maladies like poor blood circulation and the common cold.

However, yuzu is not merely confined to the realm of medicine; it has also made a significant culinary impact in the vibrant tapestry of Asian cuisine. In contrast to its citrus brethren, such as the sweet orange or mild clementine, yuzu packs a zesty punch and is seldom consumed raw. Rather, it finds its way into cocktails, teas, and both sweet and savory dishes through its juice, rinds, and seeds.

Beneath its tart exterior, yuzu harbors a wealth of health-promoting nutrients and plant compounds, including vitamin C and essential oils, that have the potential to positively impact human health in a multitude of ways. Here, we embark on an exploration of yuzu’s full potential, delving into its myriad health benefits, nutritional attributes, and creative culinary applications.

A Bounteous Source of Vitamin C

Vitamin C, a water-soluble nutrient vital for human health, is found in abundance within yuzu. Our bodies depend on a consistent dietary supply of vitamin C since we lack the capacity to synthesize or store it. This essential nutrient fulfills numerous pivotal roles within the body, such as collagen production, aiding in the absorption of dietary iron, facilitating protein metabolism, bolstering immune function, and contributing to the synthesis of neurotransmitters like dopamine and norepinephrine.

Furthermore, vitamin C stands as a stalwart defender of our cells, acting as a potent antioxidant. It tirelessly neutralizes unstable compounds known as free radicals, preventing oxidative damage. Notably, vitamin C also rejuvenates other antioxidants in our system, including vitamin E.

Studies affirm that yuzu is an exceptional source of vitamin C, surpassing certain popular citrus fruits like mandarins and limes. Just a single tablespoon of yuzu juice delivers 15 milligrams (mg) of vitamin C, constituting 17% of the daily recommended value. In comparison, an equivalent serving of fresh lemon juice contains a mere 6 mg, or 7% of the recommended daily intake.

Adequate vitamin C consumption is integral to overall health. Research demonstrates that individuals who maintain diets rich in vitamin C enjoy a reduced risk of numerous health conditions compared to those with lower dietary intake.

A 2021 study, spanning data from over 52,000 individuals, unveiled that elevated blood levels of vitamin C correlated with a decreased risk of cardioembolic stroke, a type of stroke stemming from blood clot formation in the heart, as well as Alzheimer’s disease.

Moreover, a comprehensive 2021 review, amalgamating 57 meta-analyses, illuminated the protective potential of vitamin C. Comparing high versus low vitamin C intake, this meta-analysis revealed that heightened vitamin C consumption was associated with a significantly diminished risk of bladder cancer, breast cancer, endometrial cancer, prostate cancer, and kidney cancer. Additionally, it indicated that elevated vitamin C intake curtailed the risk of death attributed to breast cancer and breast cancer recurrence.

These findings underpin the notion that augmenting one’s diet with vitamin C-rich fruits, such as yuzu, could emerge as an efficacious strategy for safeguarding one’s health.

An Array of Beneficial Plant Compounds

Beyond its vitamin C content, yuzu boasts an impressive array of plant compounds that confer health benefits. The peel and juice of yuzu emerge as prime sources of antioxidants, prominently featuring hesperidin and naringin, the two most concentrated flavonoid compounds in yuzu juice.

Flavonoids, prevalent in citrus fruits like yuzu, including hesperidin and naringin, are celebrated for their multifaceted contributions to health. Scientific investigation has revealed their ability to reduce oxidative stress, quell inflammation, enhance blood sugar regulation, and amplify insulin sensitivity. These attributes render citrus flavonoids invaluable in promoting overall well-being.

For instance, the protective compounds contained within yuzu and its citrus counterparts have demonstrated the potential to combat cellular damage, diminish inflammation, and lower specific risk factors for diseases. This may elucidate why diets rich in citrus fruits have exhibited protective effects against an array of health conditions, spanning from cardiovascular ailments to certain malignancies.

Elevating Mood Through Aromatherapy

Yuzu unfurls its pleasurable fragrance, frequently commandeered for aromatherapy endeavors. Emerging research hints at the capacity of yuzu essential oils to elevate mood, reduce heart rate, and alleviate emotional distress in select populations.

A 2017 study, involving 17 women grappling with premenstrual symptoms, observed that inhaling yuzu essential oil for a mere ten minutes significantly lowered heart rate and ameliorated premenstrual symptoms, encompassing tension, anxiety, anger, hostility, and fatigue.

Additionally, a 2021 study involving 32 adults unearthed that a two-minute session of inhaling yuzu essential oil culminated in reduced sensations of fatigue and an enhancement in feelings of refreshment. Remarkably, this yuzu-based treatment not only improved task performance but also boosted the concentration of oxygenated blood within the brain.

These preliminary findings indicate that yuzu aromatherapy might serve as an effective avenue for uplifting mood, augmenting energy levels, and refining focus. Nevertheless, it is imperative to underscore that additional research is imperative to solidify these assertions.

A Guardian of Brain Health

Emergent research tentatively positions yuzu as a guardian of brain health. It suggests that yuzu could be instrumental in safeguarding against neurodegenerative diseases through a favorable influence on a critical guardian known as the blood-brain barrier (BBB).

The BBB comprises a protective network of specialized cells lining the inner surfaces of brain blood vessels, shielding the brain by barring entry to toxins and deleterious substances. Reactive oxygen species (ROS) are implicated in BBB breakdown and brain inflammation, contributing to cognitive impairment.

Yuzu, enriched with compounds like vitamin C and hesperidin, may exert a protective effect against BBB degradation and dysfunction. This protective action is achieved by inhibiting damage to claudin-5, a protein responsible for sealing the BBB and regulating its permeability. Dysfunctional claudin-5 has been associated with neurological disorders, encompassing Alzheimer’s disease, multiple sclerosis, and depression.

Furthermore, the antioxidants housed within yuzu hold the potential to thwart inflammation and oxidative harm in the brain, further fortifying protection against cognitive deterioration.

While these preliminary findings hold promise, it is crucial to acknowledge that research remains limited at this juncture, mandating further exploration to elucidate yuzu’s full spectrum of benefits and its capacity to shield brain health.

Unraveling the Nutritional Tapestry of Yuzu

Due to its intense tartness, yuzu is seldom savored in its raw form. Instead, its juice and zest are judiciously employed in recipes, spanning from invigorating cocktails and soothing teas to decadent desserts and savory meat dishes.

Per 3.5 ounces of yuzu juice, the following nutritional composition unfolds:

• Calories: 67
• Carbohydrates: 20 grams (g)
• Iron: 1.2 mg or 7 of the Daily Value (DV)
• Vitamin C: 100 mg or 111% of the DV

Yuzu juice emerges as a low-calorie yet carb-rich elixir, densely packed with vitamin C. Additionally, it contains a smattering of iron, a mineral crucial for growth, development, and the production of hemoglobin—the essential oxygen-carrying component within blood.

It is imperative to bear in mind that yuzu is traditionally employed in modest quantities. For example, a tablespoon of yuzu juice suffices for imparting its signature tang to a cocktail, while a teaspoon of its zest can infuse a marinade with citrusy exuberance. This is due to yuzu’s potent sourness, which can readily overpower other flavors in culinary endeavors.

Navigating the Risks of Yuzu

Yuzu is generally safe for consumption, provided it is enjoyed judiciously. Excessive consumption of any intensely acidic and sour foodstuff may lead to gastrointestinal discomfort, underscoring the importance of moderation when indulging in yuzu.

Nevertheless, it is imperative to note that yuzu belongs to the citrus family and is, therefore, a potential hazard for individuals harboring citrus allergies. Those with known citrus allergies should exercise caution by avoiding yuzu and yuzu-based products.

Furthermore, while research in humans is sparse, studies conducted on rodents suggest that yuzu possesses blood-thinning properties. Consequently, individuals prescribed blood-thinning medications, such as Warfarin, should exercise prudence and limit their consumption of substantial quantities of yuzu.

A Symphony of Culinary Creativity with Yuzu
