6 Evidence-Based Health Benefits of Lemons
These nutrients are responsible for several health benefits.
In fact, lemons may support heart health, weight control and digestive health.
Here are 6 evidence-based health benefits of lemons.
1. Support Heart Health
Lemons are a good source of vitamin C.
One lemon provides about 31 mg of vitamin C, which is 51% of the reference daily intake (RDI).
For instance, one study revealed that eating 24 grams of citrus fiber extract daily for a month reduced total blood cholesterol levels (6).
Lemons are high in heart-healthy vitamin C and several beneficial plant compounds that may lower cholesterol.
2. Help Control Weight
Lemons are often promoted as a weight loss food, and there are a few theories as to why this is.
One common theory is that the soluble pectin fiber in them expands in your stomach, helping you feel full for longer.
That said, not many people eat lemons whole. And because lemon juice contains no pectin, lemon juice drinks will not promote fullness in the same way.
Another theory suggests that drinking hot water with lemon will help you lose weight.
Other theories suggest that the plant compounds in lemons may aid weight loss.
In one study, mice on a fattening diet were given lemon polyphenols extracted from the peel. They gained less weight and body fat than other mice (14).
However, no studies confirm the weight loss effects of lemon compounds in humans.
Animal studies show that lemon extract and plant compounds may promote weight loss, but the effects in humans are unknown.
3. Prevent Kidney Stones
Kidney stones are small lumps that form when waste products crystallize and build up in your kidneys.
They are quite common, and people who get them often get them repeatedly.
Lemon juice may help prevent kidney stones. However, more quality research is needed.
4. Protect Against Anemia
Iron deficiency anemia is quite common. It occurs when you don't get enough iron from the foods you eat.
Your gut absorbs iron from meat, chicken and fish (known as heme iron) very easily, while iron from plant sources (non-heme iron) not as easily. However, this absorption can be improved by consuming vitamin C and citric acid.
Because lemons contain both vitamin C and citric acid, they may protect against anemia by ensuring that you absorb as much iron as possible from your diet.
Lemons contain vitamin C and citric acid, which help you absorb non-heme iron from plants. This may prevent anemia.
5. Reduce Cancer Risk
A healthy diet rich in fruits and vegetables may help prevent some cancers (28).
Another study used pulp from mandarins that contained the plant compounds beta-cryptoxanthin and hesperidin, which are also found in lemons.
The study discovered that these compounds prevented malignant tumors from developing in the tongues, lungs, and colons of rodents (40).
However, it should be noted that the research team used a very high dose of the chemicals — far more than you would get by eating lemons or oranges.
While some plant compounds from lemons and other citrus fruits may have anticancer potential, no quality evidence suggests that lemons can fight cancer in humans.
Some plant chemicals found in lemons have been shown to prevent cancer in animal studies. However, human studies are needed.
6. Improve Digestive Health
Lemons are made up of about 10% carbs, mostly in the form of soluble fiber and simple sugars.
The main fiber in lemons is pectin, a form of soluble fiber linked to multiple health benefits.
However, to get the benefits of fiber from lemons, you need to eat the pulp.
People who drink lemon juice, without the fiber found in the pulp, will miss out on the benefits of the fiber.
The soluble fiber in lemons could help improve digestive health. However, you need to eat the pulp of the lemon, not just the juice.
The Bottom Line
Lemons contain a high amount of vitamin C, soluble fiber, and plant compounds that give them a number of health benefits.
Lemons may aid weight loss and reduce your risk of heart disease, anemia, kidney stones, digestive issues, and cancer.
Not only are lemons a very healthy fruit, but they also have a distinct, pleasant taste and smell that make them a great addition to foods and drinks.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.
Sweden is a world leader in renewable energy consumption. Swedish Institute/World Bank
Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Scaling Up<p>A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, <a href="https://www.eonenergy.com/blog/2019/February/sweden-smart-city" target="_blank">has scaled up the smart grid principle</a>. Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
