These values are approximate and can vary based on factors
such as the specific variety of lime and growing conditions.
Keep in mind that the nutritional content may change when
consuming lime juice or zest, as opposed to the whole fruit.
In addition to the nutritional value of limes, lime water may
have the following benefits:
1. Promotes water consumption
The Centers
for Disease Control and Prevention (CDC) suggest that people
who do not drink enough water could add a squeeze of lime or
lime wedge to enhance the flavor, which may encourage them to
drink more water throughout the day.
2. Might reduce the risk of certain cancers
Several studies show a link between citrus fruit, such as limes,
and a reduced risk of some types of cancer.
A 2015 meta-analysis of observational studies published in Medicine showed a possible
link between increased citrus fruit consumption and a diminished
risk of esophageal cancer.
Researchers have also demonstrated that people with the highest
intakes of citrus fruit, compared with those with the lowest,
experienced a 9%
reduction in lung cancer
risk.
However, scientists require more research on citrus fruit intake
across different cancer types, including when people add lime to
water, before they can make definitive conclusions.
3. Could play a role in overall skin health
Limes are an excellent source of vitamin
C. Vitamin C is an antioxidant that
the body needs to make collagen, which is a
compound involved in supporting overall skin
health.
According to a study in the journal Clinical,
Cosmetic and Investigational Dermatology, researchers
suggest that drinking higher amounts of water (more than 13 cups
per day) may have positive effects on skin hydration and
appearance.
Not only does adding lime to water make it easier to drink, but
the combination of water and lime juice can help improve the
appearance and health of the skin. While medical professionals
commonly understand the health benefits of both lime and water,
they currently do not have any supporting scientific studies.
4. Might support weight loss
Several studies have looked at the relationship between drinking
water and weight loss. While there is some scientific
evidence in support of this link, scientists are unclear why
this relationship exists and suggest they need further research.
A review
paper from 2019 on drinking water
and weight loss confirms that the current evidence on water and
weight loss is low to moderate in quality.
Citrus fruits, such as limes, may have bioactive
compounds that could help
control weight, but doctors require further research to better
understand the role limes and water may play in promoting weight
loss.
5. Could help support immune function
The body needs vitamin C to support the normal
functioning of the immune
system. A person’s body cannot make vitamin C on its own so they
must get it from foods or other sources. One lime contains 19.5
mg of vitamin C.
When a person consumes it regularly, lime water can help
strengthen the body’s defenses and may shorten the lifespan of
colds and cases of flu,
although there is limited scientific evidence to support this.
6. Might contribute to a lower risk of heart disease
According to the CDC, following a healthy
eating pattern that contains fresh
fruit, including citrus fruits such as limes, is important for
preventing heart disease and its complications.
Researchers recently addressed this in a 2020 systematic review
and meta-analysis of observational studies in the Journal
of the American Heart Association.
Findings from this study suggest that higher total fruit intake
has links with a lower risk of heart disease, and the
researchers saw greater benefits specifically for citrus fruits
among other fruit and vegetable sources.
Scientists need additional clinical studies to confirm the role
that citrus fruits, such as limes, play in reducing the risk of
heart disease.
Because drinking
enough water daily is important for normal function of the
body, including the heart, using limes may be
an effective and tasty way to promote increased water
consumption.
7. Could have anti-inflammatory properties
With 22% of the daily recommended value for vitamin C in one
lime, they are rich
in this nutrient.
Among many other potential benefits, vitamin C acts as an anti-inflammatory
agent in the body. There are also bioactive components in citrus fruits and juices,
including limes, that may have involvement in supporting a
functional response of the immune system and controlling
inflammation, according to a review paper in Frontiers
in Immunology.
Scientists need additional well-designed studies in humans to
explore the role that citrus fruits may play in lowering
inflammation.
8. Might help prevent kidney stones
Limes contain both citric acid and vitamin C. Several research
studies in a 2015 scientific review paper have shown the ability
of citrus fruits containing these nutrients to break up or
prevent the formation of some types of kidney
stones.
The National
Kidney Foundation suggests that a risk factor for kidney
stone formation is not drinking enough water. Lime water could
be one solution to help a person meet daily fluid
recommendations.
