Lemons are known for adding freshness and flavor to food and beverages. Who doesn’t love a cold glass of delicious lemonade on a hot day? However, lemons aren’t just a tasty source of vitamin C. They also pack a powerful nutritional punch.
Let’s go in-depth on lemon nutrition and explore some interesting ways to add more lemons to your diet.
Lemon Nutrition Facts
When it comes to nature’s most nutritious foods, it’s hard to beat the simple lemon. Lemon nutrition is well-documented in scientific research. In fact, one lemon is chock-full of vitamins, essential nutrients, phytonutrients, minerals, and antioxidants. Let’s explore the nutrition content of lemons.
Vitamins In Lemons
Lemons and other citrus fruits are best known for being incredible sources of vitamin C. In fact, the juice from just one lemon provides 30.7 milligrams of vitamin C, which translates to 50% of the body’s recommended reference daily intake (RDI).
We all know that we need a healthy intake of vitamin C, and lemons pack a powerful nutritional punch. Here is the breakdown of the vitamins that are found in one whole lemon.
- Lemon calories: 21.6
- Fat: <1g
- Vitamin C: 30.7mg
- Carbohydrates: 5.4g
- Fiber: 1.6g
- Protein: 0.6g
- Sodium: 1mg
- Sugars: 1.5g
- Potassium: 80mg
- Vitamin A: 32.4 IU
- Vitamin B6: 0.1mg
The carbohydrates in lemons are mostly fiber (1.6g) and sugar (1.5g).
Furthermore, with a glycemic load of 1, lemons are a low-glycemic food.
In addition to the vitamins listed above, lemons also contain trace amounts of the following minerals.
Also, one lemon has about 94.4 grams of water, so it’s incredibly hydrating.
Surprisingly, lemon pulp is an excellent source of dietary fiber. One lemon has approximately 1.6 grams of soluble fiber.
Lemons are one of the best foods for vitamin C, which gives lemons powerful antioxidant properties. Antioxidants may help lower disease incidence, including cardiovascular diseases, neurodegenerative diseases, DNA damage, and even some cancers.
Why Lemons Are So Good For You
We’ve shared at length the role of lemon in providing vitamin C, but there is a lot more to the lemon. A study conducted in 2018 was published in the International Journal of Nutrition and Food Engineering found that when lemons are added to other foods, they serve as an effective exigent food.
What this means is that in addition to the nutritional value lemons add, they bring out further benefits in the foods with which they are combined.
Specifically, the study referenced the carotenoids that are found in mashed or boiled carrots. When the carrots were combined with whey curd, olive oil, and lemon juice, the nutrients in the carrots were almost 30% more bioaccessible than carrots without the other foods added.
The Amazing Health Benefits of Lemons
Below, we have listed some evidence-based nutritional benefits of lemons.
Prevention of Vitamin C Deficiency
Because one lemon provides about half of the amount of vitamin C you need every day, including lemons or lemon juice in your diet will help prevent vitamin C deficiency.
Heart Health Support
When you eat foods that are rich in vitamin C, you have a decreased risk of stroke and cardiovascular disease caused by high blood pressure. And it’s not just the vitamin C in lemons that contribute to decreased coronary heart diseases. The plant compounds and fibers found in lemons also significantly lower some heart disease risk factors.
Lemons are an excellent source of citrus fiber. In terms of how citrus fiber affects your health, one study demonstrated that people who eat 24 grams daily of citrus fiber extract have reduced total blood cholesterol levels (including the bad LDL cholesterol) after one month.
Possible Aid in Weight Control
Theories abound as to the benefit of lemons for people who are trying to lose weight. However, there is some basis in fact. Research has shown that the plant compounds present in lemon extract may actually help people reduce or prevent weight gain.
Increased Immune Function
It’s commonly known that vitamin C plays a significant role in immune function. Some studies have shown that taking vitamin C supplements can even reduce the duration of a cold.
Decreased Age-Related Decline
Because vitamin C is one of the most powerful antioxidants, eating lemons could slow down age-related decline. Some evidence suggests that vitamin C and other antioxidants help improve the health of the skin. Also, antioxidants may help prevent some types of diseases that are commonly associated with growing older.
Help with Liver Disease
A 2017 study on animals suggested that consuming lemons may help with livers that have been damaged. Rodents in the study had liver damage from alcohol consumption, and after consuming lemon juice, they showed improved liver function.
Possible Cancer Prevention
Studies have confirmed that a balanced diet rich in vegetables and fruits may help prevent certain types of cancer.
The National Cancer Institute says that increased antioxidant levels may help prevent free radical damage that is often associated with the development of cancer cells.
Kidney Stone Prevention
Kidney stones form when waste products crystallize and slowly build up in the kidneys. Because citric acid increases urine volume and increases the pH of urine, consuming foods that have citric acid may help you to prevent kidney stones.
Improved Digestive Health
Lemons have carbs that are in the form of simple sugars and soluble fiber. In lemons, the main fiber present is pectin, which has been linked to numerous health benefits.
There is a caveat. To enjoy the fiber benefits of lemons, you need to eat the pulp.
Protection Against Anemia
Anemia occurs when you don’t get sufficient iron from foods you consume. While lemons contain trace amounts of iron, the magic happens because of how citric acid and vitamin C improve how your body absorbs iron from the foods you eat.
In a book published in 2017, the case was made for the antimicrobial properties of lemons. Specifically, the book described how lemon peel solvents showed antimicrobial activity against staphylococcus, salmonella, and other pathogenic bacteria.
Also, a 2017 study found that sweet lemon juice that had been fermented demonstrated antibacterial activity against the deadly E. coli bacteria.
What About Sugar?
One whole lemon has only 1.5 grams of sugar.
Other Side Effects and Health Risks of Lemons
Are there side effects of eating lemons?
Citrus allergy is uncommon, but it can affect some people. If you’re allergic to other citrus fruits, avoid lemon or products that are made of lemon zest or lemons in general.
Also, there have been reports of asthma reactions from some people with this health condition who inhaled orange or lemon peel.
Teeth Enamel Damage
Acidic fruits and vegetables take a toll on tooth enamel. Specifically, the acid found in lemon juice can strip your tooth enamel and make them sensitive or weak.
If you drink lemon water, sip it through a straw to minimize contact with your teeth.
Heartburn and Gastric Reflux
Another problem that can occur with consuming too much lemon juice is heartburn or gastric reflux problems in people who struggle with this health condition.
