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.

Billions worth of valuable metals such as gold, silver and copper were dumped or burned last year as electronic waste produced globally jumped to a record 53.6 million tons (Mt), or 7.3 kilogram per person, a UN report showed on Thursday.
Environmental and Health Hazard<p>Experts say e-waste, which is now the world's fastest-growing domestic waste stream, poses serious environmental and health risks.</p><p>Simply throwing away electronic items without ensuring they get properly recycled leads to the loss of key materials such as iron, copper and gold, which can otherwise be recovered and used as primary raw materials to make new equipment, thereby reducing greenhouse gas emissions from extraction and refinement of raw materials.</p><p>Refrigerants found in electronic equipment such as fridge and air conditioners also contribute to global warming. A total of 98 Mt of CO2-equivalents, or about 0.3% of global energy-related emissions, were released into the atmosphere in 2019 from discarded refrigerators and ACs that were not recycled properly, the report said.</p><p>E-waste contains several toxic additives or hazardous substances, such as mercury and brominated flame retardants (BFR), and simply burning it or throwing it away could lead to serious health issues. Several studies have linked unregulated recycling of e-waste to adverse birth outcomes like stillbirth and premature birth, damages to the human brain or nervous system and in some cases hearing loss and heart troubles.</p><p>"Informal and improper e-waste recycling is a major emerging hazard silently affecting our health and that of future generations. One in four children are dying from avoidable environmental exposures," said Maria Neira, director of the Environment, Climate Change and Health Department at the World Health Organization. "One in four children could be saved, if we take action to protect their health and ensure a safe environment."</p>
Europe Leads the Way<p>While most of the e-waste was generated in Asia (24.9 Mt) in 2019, Europe led the charts on a per person basis with 16.2 kg per capita, the report said.</p><p>But the continent also recorded the <a href="https://www.dw.com/en/the-eu-declares-war-on-e-waste/a-51108790" target="_blank">highest documented formal e-waste collection and recycling</a> rate at 42.5%, still below its target of 65%. Europe was well ahead of the others on this front. Asia ranked second with 11.7%.</p><p>The authors said while more that 70% of the world's population was covered by some form of e-waste policy or laws, not much was being done toward implementation and enforcement of the regulations to encourage the take-up of a collection and recycling infrastructure due to lack of investment and political motivation.</p><p>"You have to think about new economic systems," said Kühr.</p><p>One approach could be that consumers no longer buy the products, but only the service they offer. The device would remain the property of the maker, who would then have an interest in offering his customers the best service and the necessary equipment. The maker would also be interested in designing his products in such a way that they are easier to repair and easier to recycle, Kühr said.</p>

Did you know that some snakes can fly?
The south Asian paradise tree snake (Chrysopelea paradisi) can launch itself into the air and glide from one tree branch to another. And when it does, it moves its body in waves in something known as aerial undulation. Scientists have long known how the snakes moved. But they didn't know why. Until now.
The Cube is home to a 23-camera motion capture system. Jake Socha
The snakes wore 11 to 17 infrared-reflective markers, which gave the team high-resolution data while still allowing the animals to move freely. Jake Socha

For some combat veterans, the Fourth of July is not a time to celebrate the independence of the country they love. Instead, the holiday is a terrifying ordeal. That's because the noise of fireworks – loud, sudden, and reminiscent of war – rocks their nervous system. Daily fireworks in many U.S. cities in recent weeks have no doubt been interfering with the sleep and peace of mind of thousands of veterans.
What Is PTSD?<p><a href="https://theconversation.com/veterans-refugees-and-victims-of-war-crimes-are-all-vulnerable-to-ptsd-130144" target="_blank">PTSD</a> can occur when someone is exposed to extreme exposure traumatic experience. Typically, the trauma involves a threat of death, serious injury, or sexual violence. Along with war veterans, it happens to refugees; to victims of gun violence, rape and other physical assaults; and to survivors of car accidents and natural disasters like earthquakes or tornadoes.</p><p>PTSD can also happen by witnessing trauma or its aftermath, often the case with <a href="https://www.psychiatry.org/patients-families/ptsd/what-is-ptsd" target="_blank">first responders</a> and <a href="https://www.psychologytoday.com/us/blog/the-many-faces-anxiety-and-trauma/202006/invisible-wounds-the-frontline-heroes" target="_blank">front-line workers</a>.</p><p>All this adds up to tens of millions of Americans. Up to 30% of combat veterans and first responders, and 8% of civilians, <a href="https://www.ptsd.va.gov/professional/treat/essentials/epidemiology.asp" target="_blank">fulfill the diagnostic criteria for PTSD</a>. And that criteria is not easily met: symptoms of PTSD include nightmares, flashbacks, intrusive trauma memories, difficulty sleeping, avoidance of reminders of trauma, negative emotions, and what we call "hyperarousal symptoms."</p>
Fireworks Can Trigger Flashbacks<p>Hyperarousal, a core component of PTSD, occurs when a person is hyper-alert to any sign of threat – constantly on edge, easily startled and continuously screening the environment.</p><p>Imagine, for instance, stepping down the stairs in the dark after hearing a noise; you're worried an intruder might be downstairs. Then a totally unpredictable loud sound explodes right outside your window.</p><p>For people with PTSD, that sound – reminiscent of gunfire, a thunderstorm or a car crash – <a href="https://theconversation.com/veterans-refugees-and-victims-of-war-crimes-are-all-vulnerable-to-ptsd-130144" target="_blank">can cause</a> a panic attack or trigger flashbacks, a sensory experience that makes it seem as if the old trauma is happening here and now. Flashbacks can be so severe that combat veterans may suddenly drop to the ground, the same way they would when an explosion took place in combat. Later, the experience can trigger nightmares, insomnia or worsening of other PTSD symptoms.</p><p>Those of us who set off fireworks need to ask ourselves: Are those few minutes of fun worth the hours, days, or weeks of torment that will begin for some of our friends and neighbors – including many who put their lives on the line to protect us?</p>
Who Else Is Affected?<p>Millions of others, though not diagnosed with PTSD, may similarly be affected by fireworks. <a href="https://adaa.org/about-adaa/press-room/facts-statistics" target="_blank">One in five Americans</a> have an anxiety disorder, many with symptoms of hyperarousal. Also impacted are those with autism or developmental disabilities; they find it difficult to cope with the noise, or just the drastic change from life routines. Then there are people who have to work, holiday or not: nurses, physicians and first responders, who have to be up at 4 a.m. for a 30-hour shift.</p><h3>How to Reduce the Negative Impact</h3><p>There are ways to reduce how fireworks affect others:</p><ul><li>For those with PTSD, the unexpected nature of fireworks is probably the worst part. So at least make it as predictable as possible. Do it in designated areas during designated times. Don't explode one, for instance, two hours after the designated time window. And avoid setting them off <a href="https://www.theguardian.com/society/2018/jul/04/fireworks-ptsd-fourth-of-july-veterans-shooting-survivors" target="_blank">on the 3rd</a>. People are less prepared then.</li><li>If you're aware that a veteran or trauma survivor lives in the neighborhood, move the noise as far as possible from their home and give them prior warning. Consider putting a sign in your front yard noting the time you'll set the fireworks.</li><li>Remember, it doesn't have to be super loud to make it fun. Consider using <a href="https://thehill.com/opinion/energy-environment/504964-its-time-for-silent-fireworks" target="_blank">silent fireworks</a>. And you don't have to be the one who lights the fireworks. Simply enjoy watching while your city or township does it safely.</li></ul>
