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). Research shows that eating fruits and vegetables rich in vitamin C reduces your risk of heart disease and stroke.
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.
However, drinking water is known to temporarily increase the number of calories you burn, so it may be the water itself that is helping with weight loss — not the lemon.
3. Prevent Kidney Stones
Citric acid may help prevent kidney stones by increasing urine volume and increasing urine pH, creating a less favorable environment for kidney stone formation.
4. Protect Against Anemia
Iron deficiency anemia is quite common. It occurs when you don’t get enough iron from the foods you eat. Lemons contain some iron, but they primarily prevent anemia by improving your absorption of iron from plant foods.
5. Reduce Cancer Risk
A healthy diet rich in fruits and vegetables may help prevent some cancers.
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.
Soluble fiber can improve gut health and slow the digestion of sugars and starches. These effects may result in reduced blood sugar levels.
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 makes them a great addition to foods and drinks.
