The loquat (Eriobotrya japonica) is a tree native to China that's prized for its sweet, citrus-like fruit.
Loquats are small, round fruits that grow in clusters. Their color varies from yellow to red-orange, depending on the variety.
Loquat fruit, seeds, and leaves are packed with powerful plant compounds and have been used in traditional medicine for thousands of years.
Recent research suggests that loquats may offer a variety of health benefits, including protection against some diseases.
Here are 7 surprising health benefits of loquats.
1. High in Nutrients
Loquats are low-calorie fruits that provide numerous vitamins and minerals, making them very nutritious.
One cup (149 grams) of cubed loquats contains (1):
- Calories: 70
- Carbs: 18 grams
- Protein: 1 gram
- Fiber: 3 grams
- Provitamin A: 46% of the Daily Value (DV)
- Vitamin B6: 7% of the DV
- Folate (vitamin B9): 5% of the DV
- Magnesium: 5% of the DV
- Potassium: 11% of the DV
- Manganese: 11% of the DV
These fruits are particularly high in carotenoid antioxidants, which prevent cellular damage and may protect against disease. Carotenoids are also precursors to vitamin A, which is essential for healthy vision, immune function, and cellular growth (2Trusted Source).
Additionally, loquats contain small amounts of vitamin C, thiamine (vitamin B1), riboflavin (vitamin B2), copper, iron, calcium, and phosphorus.
Loquats are low-calorie fruits that provide an array of nutrients, including provitamin A, several B vitamins, magnesium, potassium, and manganese.
2. Packed With Plant Compounds
Loquats' plant compounds benefit your health in several ways.
For example, they're an excellent source of carotenoid antioxidants, including beta carotene — though darker, red or orange varieties tend to offer more carotenoids than paler ones (8Trusted Source).
A review of 7 studies also associated high beta carotene intake with a significantly lower risk of death from all causes, compared with low beta carotene intake (12Trusted Source).
What's more, loquats are rich in phenolic compounds, which possess antioxidant, anticancer, and anti-inflammatory properties and may help safeguard against several conditions, including diabetes and heart disease (13Trusted Source, 14Trusted Source, 15Trusted Source).
Loquats are an excellent source of carotenoids and phenolic compounds, which offer plenty of health benefits.
3. May Promote Heart Health
Loquats may bolster heart health due to their concentration of vitamins, minerals, and antioxidants.
Carotenoids have powerful anti-inflammatory and antioxidant effects that help prevent plaque buildup in your arteries, which is the leading cause of heart disease and heart-disease-related death (21Trusted Source).
In fact, studies reveal that people who eat more carotenoid-rich foods have a significantly reduced risk of heart disease, compared with those who eat fewer of these foods (22Trusted Source, 23Trusted Source).
Loquats are rich in potassium, magnesium, carotenoids, and phenolic compounds, all of which may boost heart health and protect against heart disease.
4. May Have Anticancer Properties
For instance, one test-tube study showed that extract from loquat fruit skins significantly inhibited the growth and spread of human bladder cancer cells (26).
Additionally, substances in loquats' skin and flesh, including carotenoids and phenolic compounds, are known to possess anticancer properties.
Beta carotene has exhibited cancer-fighting effects in both test-tube and animal studies, while chlorogenic acid — a phenolic compound — has been shown to suppress tumor growth in multiple test-tube studies (27Trusted Source, 28Trusted Source, 29Trusted Source, 30Trusted Source).
Nonetheless, more studies on loquats are needed.
Though loquats may have anticancer properties, more research is necessary.
5. May Improve Metabolic Health
Loquats may improve metabolic health by reducing levels of triglycerides, blood sugar, and insulin — a hormone that helps move blood sugar into your cells to be used for energy.
Various parts of the loquat tree, including its leaves and seeds, have long been used in traditional Chinese medicine to treat metabolic issues like high blood sugar (35Trusted Source).
However, human studies are necessary.
Loquat fruit, leaves, and seeds may benefit several aspects of metabolic health, but human studies are lacking.
6. May Offer Anti-Inflammatory Properties
Some research suggests that loquats have powerful anti-inflammatory properties.
In a test-tube study, loquat juice significantly increased levels of an anti-inflammatory protein called interleukin-10 (IL-10) while significantly decreasing levels of two inflammatory proteins — interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) (42).
Additionally, a rodent study found that supplementing with loquat fruit extract reduced overall inflammation caused by a high-sugar diet and significantly lowered levels of endotoxins, a type of inflammatory substance, in the liver (43Trusted Source).
These potent anti-inflammatory effects are likely due to loquats' wide array of antioxidants, vitamins, and minerals. All the same, human research is needed.
Test-tube and animal research suggests that loquats may have powerful anti-inflammatory effects.
7. Versatile and Scrumptious
Loquats grow in semitropical environments. In these regions, they may be purchased from local farmers or even grown in backyards.
If you live in a colder climate, they're harder to find but may be available at specialty grocery stores depending on the time of year.
Loquats taste sweet, yet slightly tart, with notes of citrus. Be sure to choose fully ripe loquats, as immature fruit is sour. Ripe ones turn a bright yellow-orange and are soft to the touch.
As loquats rot quickly, you should eat them within a few days of purchase.
You can add them to your diet in a variety of ways, including:
- raw, paired with cheese or nuts as a snack
- tossed into a fruit salad
- stewed with maple syrup and cinnamon as a sweet topping for oatmeal
- baked into pies and cakes
- made into jam or jelly
- added to a smoothie alongside spinach, Greek yogurt, avocado, coconut milk, and frozen banana
- combined with peppers, tomatoes, and fresh herbs for a delectable salsa
- cooked and served with meat or poultry as a sweet side
- juiced for cocktails and mocktails
If you aren't planning on enjoying loquats immediately, you can refrigerate them for up to 2 weeks. You can also dehydrate, can, or freeze them to extend their shelf life (44).
Loquats' sweet, slightly tart taste pairs well with many dishes. These fruits are delicate and don't keep for long, so you may want to preserve them through freezing, canning, or dehydrating. You can also make them into jams and jellies.
The Bottom Line
Loquats are delicious fruits that offer a variety of health benefits.
They're low in calories but boast plenty of vitamins, minerals, and anti-inflammatory plant compounds.
Plus, some research suggests that they may safeguard against certain conditions, such as heart disease and cancer, as well as reduce blood sugar, triglyceride, and insulin levels.
If you're curious, try to find loquats at your local specialty store. You can also buy loquat tea, syrup, candy, and seedlings online.

The patient in the case report (let's call him Tom) was 54 and in good health. For two days in May, he felt unwell and was too weak to get out of bed. When his family finally brought him to the hospital, doctors found that he had a fever and signs of a severe infection, or sepsis. He tested positive for SARS-CoV-2, the virus that causes COVID-19 infection. In addition to symptoms of COVID-19, he was also too weak to move his legs.
When a neurologist examined him, Tom was diagnosed with Guillain-Barre Syndrome, an autoimmune disease that causes abnormal sensation and weakness due to delays in sending signals through the nerves. Usually reversible, in severe cases it can cause prolonged paralysis involving breathing muscles, require ventilator support and sometimes leave permanent neurological deficits. Early recognition by expert neurologists is key to proper treatment.
We are neurologists specializing in intensive care and leading studies related to neurological complications from COVID-19. Given the occurrence of Guillain-Barre Syndrome in prior pandemics with other corona viruses like SARS and MERS, we are investigating a possible link between Guillain-Barre Syndrome and COVID-19 and tracking published reports to see if there is any link between Guillain-Barre Syndrome and COVID-19.
Some patients may not seek timely medical care for neurological symptoms like prolonged headache, vision loss and new muscle weakness due to fear of getting exposed to virus in the emergency setting. People need to know that medical facilities have taken full precautions to protect patients. Seeking timely medical evaluation for neurological symptoms can help treat many of these diseases.
What Is Guillain-Barre Syndrome?
Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Most commonly, the injury involves the protective sheath, or myelin, that wraps nerves and is essential to nerve function.
Without the myelin sheath, signals that go through a nerve are slowed or lost, which causes the nerve to malfunction.
To diagnose Guillain-Barre Syndrome, neurologists perform a detailed neurological exam. Due to the nerve injury, patients often may have loss of reflexes on examination. Doctors often need to perform a lumbar puncture, otherwise known as spinal tap, to sample spinal fluid and look for signs of inflammation and abnormal antibodies.
Studies have shown that giving patients an infusion of antibodies derived from donated blood or plasma exchange – a process that cleans patients' blood of harmful antibodies - can speed up recovery. A very small subset of patients may need these therapies long-term.
The majority of Guillain-Barre Syndrome patients improve within a few weeks and eventually can make a full recovery. However, some patients with Guillain-Barre Syndrome have lingering symptoms including weakness and abnormal sensations in arms and/or legs; rarely patients may be bedridden or disabled long-term.
Guillain-Barre Syndrome and Pandemics
As the COVID-19 pandemic sweeps across the globe, many neurologic specialists have been on the lookout for potentially serious nervous system complications such as Guillain-Barre Syndrome.
Though Guillain-Barre Syndrome is rare, it is well known to emerge following bacterial infections, such as Campylobacter jejuni, a common cause of food poisoning, and a multitude of viral infections including the flu virus, Zika virus and other coronaviruses.
Studies showed an increase in Guillain-Barre Syndrome cases following the 2009 H1N1 flu pandemic, suggesting a possible connection. The presumed cause for this link is that the body's own immune response to fight the infection turns on itself and attacks the peripheral nerves. This is called an "autoimmune" condition. When a pandemic affects as many people as our current COVID-19 crisis, even a rare complication can become a significant public health problem. That is especially true for one that causes neurological dysfunction where the recovery takes a long time and may be incomplete.
Though there is clear clinical suspicion that COVID-19 can lead to Guillain-Barre Syndrome, many important questions remain. What are the chances that someone gets Guillain-Barre Syndrome during or following a COVID-19 infection? Does Guillain-Barre Syndrome happen more often in those who have been infected with COVID-19 compared to other types of infections, such as the flu?
The only way to get answers is through a prospective study where doctors perform systematic surveillance and collect data on a large group of patients. There are ongoing large research consortia hard at work to figure out answers to these questions.
Understanding the Association Between COVID-19 and Guillain-Barre Syndrome
While large research studies are underway, overall it appears that Guillain-Barre Syndrome is a rare but serious phenomenon possibly linked to COVID-19. Given that more than 10.7 million cases have been reported for COVID-19, there have been 10 reported cases of COVID-19 patients with Guillain-Barre Syndrome so far – only two reported cases in the U.S., five in Italy, two cases in Iran and one from Wuhan, China.
It is certainly possible that there are other cases that have not been reported. The Global Consortium Study of Neurological Dysfunctions in COVID-19 is actively underway to find out how often neurological problems like Guillain-Barre Syndrome is seen in hospitalized COVID-19 patients. Also, just because Guillain-Barre Syndrome occurs in a patient diagnosed with COVID-19, that does not imply that it was caused by the virus; this still may be a coincident occurrence. More research is needed to understand how the two events are related.
Due to the pandemic and infection-containment considerations, diagnostic tests, such as a nerve conduction study that used to be routine for patients with suspected Guillain-Barre Syndrome, are more difficult to do. In both U.S. cases, the initial diagnosis and treatment were all based on clinical examination by a neurological experts rather than any tests. Both patients survived but with significant residual weakness at the time these case reports came out, but that is not uncommon for Guillain-Barre Syndrome patients. The road to recovery may sometimes be long, but many patients can make a full recovery with time.
Though the reported cases of Guillain-Barre Syndrome so far all have severe symptoms, this is not uncommon in a pandemic situation where the less sick patients may stay home and not present for medical care for fear of being exposed to the virus. This, plus the limited COVID-19 testing capability across the U.S., may skew our current detection of Guillain-Barre Syndrome cases toward the sicker patients who have to go to a hospital. In general, the majority of Guillain-Barre Syndrome patients do recover, given enough time. We do not yet know whether this is true for COVID-19-related cases at this stage of the pandemic. We and colleagues around the world are working around the clock to find answers to these critical questions.

One of the initial reasons social distancing guidelines were put in place was to allow the healthcare system to adapt to a surge in patients since there was a critical shortage of beds, ventilators and personal protective equipment. In fact, masks that were designed for single-use were reused for an entire week in some hospitals.

Unity Task Forces formed by presumptive Democratic presidential nominee Joe Biden and Sen. Bernie Sanders unveiled sweeping party platform recommendations Wednesday that—while falling short of progressive ambitions in a number of areas, from climate to healthcare—were applauded as important steps toward a bold and just policy agenda that matches the severity of the moment.
"We've moved the needle a lot, especially on environmental justice and upping Biden's ambition," said Sunrise Movement co-founder and executive director Varshini Prakash, a member of the Biden-Sanders Climate Task Force. "But there's still more work to do to push Democrats to act at the scale of the climate crisis."
The climate panel—co-chaired by Rep. Alexandria Ocasio-Cortez (D-N.Y.) and former Secretary of State John Kerry—recommended that the Democratic Party commit to "eliminating carbon pollution from power plants by 2035," massively expanding investments in clean energy sources, and "achieving net-zero greenhouse gas emissions for all new buildings by 2030."
In a series of tweets Wednesday night, Ocasio-Cortez—the lead sponsor of the House Green New Deal resolution—noted that the Climate Task Force "shaved 15 years off Biden's previous target for 100% clean energy."
"Of course, like in any collaborative effort, there are areas of negotiation and compromise," said the New York Democrat. "But I do believe that the Climate Task Force effort meaningfully and substantively improved Biden's positions."
Today the 6 Biden-Sanders Unity Task Forces are unveiling final language. The Climate Task Force accomplished a gr… https://t.co/gz3broq2qe— Alexandria Ocasio-Cortez (@Alexandria Ocasio-Cortez)1594240617.0
The 110 pages of policy recommendations from the six eight-person Unity Task Forces on education, the economy, criminal justice, immigration, climate change, and healthcare are aimed at shaping negotiations over the 2020 Democratic platform at the party's convention next month.
Sanders said that while the "end result isn't what I or my supporters would've written alone, the task forces have created a good policy blueprint that will move this country in a much-needed progressive direction and substantially improve the lives of working families throughout our country."
"I look forward to working with Vice President Biden to help him win this campaign," the Vermont senator added, "and to move this country forward toward economic, racial, social, and environmental justice."
Biden, for his part, applauded the task forces "for helping build a bold, transformative platform for our party and for our country."
"I am deeply grateful to Bernie Sanders for working with us to unite our party and deliver real, lasting change for generations to come," said the former vice president.
On the life-or-death matter of reforming America's dysfunctional private health insurance system—a subject on which Sanders and Biden clashed repeatedly throughout the Democratic primary process—the Unity Task Force affirmed healthcare as "a right" but did not embrace Medicare for All, the signature policy plank of the Vermont senator's presidential bid.
Instead, the panel recommended building on the Affordable Care Act by establishing a public option, investing in community health centers, and lowering prescription drug costs by allowing the federal government to negotiate prices. The task force also endorsed making all Covid-19 testing, treatments, and potential vaccines free and expanding Medicaid for the duration of the pandemic.
"It has always been a crisis that tens of millions of Americans have no or inadequate health insurance—but in a pandemic, it's potentially catastrophic for public health," the task force wrote.
Dr. Abdul El-Sayed, a former Michigan gubernatorial candidate and Sanders-appointed member of the Healthcare Task Force, said that despite major disagreements, the panel "came to recommendations that will yield one of the most progressive Democratic campaign platforms in history—though we have further yet to go."
We rein in #pharma's greed by: 1) Allowing Medicare to FINALLY negotiate Rx drugs FOR ALL AMERICANS 2) Using Rx d… https://t.co/6k9iUCLMp7— Abdul El-Sayed (@Abdul El-Sayed)1594238411.0
Observers and advocacy groups also applauded the Unity Task Forces for recommending the creation of a postal banking system, endorsing a ban on for-profit charter schools, ending the use of private prisons, and imposing a 100-day moratorium on deportations "while conducting a full-scale study on current practices to develop recommendations for transforming enforcement policies and practices at ICE and CBP."
Marisa Franco, director of immigrant rights group Mijente, said in a statement that "going into these task force negotiations, we knew we were going to have to push Biden past his comfort zone, both to reconcile with past offenses and to carve a new path forward."
"That is exactly what we did, unapologetically," said Franco, a member of the Immigration Task Force. "For years, Mijente, along with the broader immigrant rights movement, has fought to reshape the narrative around immigration towards racial justice and to focus these very demands. We expect Biden and the Democratic Party to implement them in their entirety."
"There is no going back," Franco added. "Not an inch, not a step. We must only move forward from here."
