The high levels of vitamin C in one orange 68 mg , grapefruit 77 mg , lemon 18 mg or lime 13 mg helps your body to better absorb iron. While your first instinct is to grab a water bottle if you're thirsty, roughly one quarter of all the water we consume comes from the food we eat—and oranges are about 90 percent water.
Oranges are famously high in vitamin C , an antioxidant that helps reduce free radical damage to your DNA. Feeling like you're carrying some water weight? Dig into an orange or grapefruit for breakfast to hit roughly one-tenth of your daily recommended intake of the electrolyte potassium milligrams and milligrams, respectively.

They can help reduce your risk of kidney stones. The number of nutrients and the percent of the recommended daily allowance or adequate intake met from the consumption of g of selected citrus fruit [ 22 ]. Citrus is a valuable source of vitamin C.
By consuming a moderate amount of citrus fruits each day, an individual can achieve percent Vitamin C level. It is transmitted through muscle fibers, carnitine biosynthesis, neurotransmitters, collagen, and bones because these particles connect the fibers.
The immune system can be effectively stimulated by consuming vitamin C, which boosts white blood cells [ 23 ]. When Vitamin C is taken for pregnancy, it can decrease pre-eclampsia risk [ 24 ].
Some studies indicate that vitamin C supplementation can reduce the severity of colds symptoms or duration [ 23 ]. Anti-oxidants such as Vitamin C could reduce the risk of artery stiffening and cardiovascular diseases [ 25 ]. Above mg of vitamin C daily is a healthy intake, and citrus fruits are a huge source of this vitamin. Lemon provides 37 mg of ascorbic acid per g of fruit [ 16 ].
Pomelos have There are many types of carotenoids, including terpenes responsible for pigments commonly found in plants, and there are about carotenoids in foods and 50 in human bodies [ 27 , 28 ]. The highest carotenoid levels, such as lutein, zeaxanthin, lycopene, and vitamin A, are found in fruits and vegetables, including orange and carotene. Benefits of carotenoids in foods include improving immune function, promoting bone formation, promoting eye health, and maintaining visual quality [ 22 ].
There is a large amount of data supporting that carotenoids reduce the risk of cancer, macular degeneration, cataracts, skin damage to the sun, and cardiovascular diseases [ 29 ]. Beta carotene, lycopene, or lutein may decrease the rate of UV-induced lipid peroxidation in human skin fibroblast cells [ 30 ]. Lutein is inversely related to colorectal cancer in both men and women [ 31 ].
Folic acid, which is a water-soluble vitamin, and its derivatives are collectively called folate or folacin. The most notable folate compounds in Citrus are the reduced 5-methyl tetrahydrofolate monoglutamate and polyglutamate compounds [ 34 ].
Folate plays a vital role in DNA, which is involved in homocysteine regulation and protein production primarily through the methylation transfer reactions [ 22 ].
Because there is a high DNA production during pregnancy, a folate deficiency is significantly linked to birth defects such as neural tube defects [ 35 ]. Lack of folic acid caused higher levels of homocysteine, raising heart disease and atherosclerosis [ 22 ]. The consumption of citrus fruit is an easy way to obtain vitamin C and dietary folate, which is vital for absorption in the body.
Lemon, a citrus fruits representative, has eleven to sixteen micrograms of Folate in grams [ 22 ]. According to El-Otmani and Ait-Oubahou [ 37 ] Citrus limon contained 11mg of folic acid per g of citrus.
The fiber is found in vegetables and fruits cannot be digested and absorb in the small intestine. There are two kinds of dietary fiber; soluble and insoluble fiber. Insoluble fibers are highly fermentable and connected with carbohydrate and lipid metabolism, while soluble fibers contribute to fecal bulk and reduce transit time [ 34 ]. Although pectin, cellulose, and hemicellulose comprise the most abundant dietary fiber on the plants, they also contain only trace amounts of lignin. Consumption of citrus fruit can contribute significant quantities of pectin in a diet.
Dietary incorporation of pectin appears to affect several metabolic and digestive processes; principal interest affects glucose absorption and cholesterol level [ 38 , 39 ]. There is a significant benefit in consuming citrus fruit because of its pectin content. Dietary incorporation of pectin appears to have many implications for metabolic, digestive, and health affairs. One way fiber can reduce colon cancer is by diluting and trapping the harmful chemicals in the colon from bile-absorption and bile-excretion [ 34 ].
Scientific studies have proven that fiber can help promote laxation and satiety, the uptake and reabsorption of glucose, fat, cholesterol, and bile acids, thereby lessening heart disease risk and possibly enhancing healthy intestinal microbial fermentation [ 40 , 41 ]. Citrus fruits significantly reduce cholesterol levels depending on the esterification degree of fiber consumption, viscosity, and molecular mass [ 22 ].
A fiber-rich diet has a low risk of deadly chronic diseases such as diabetes, heart disease, weight, and cancer and lowers cholesterol levels and blood sugar [ 42 ]. Several epidemiological studies reported that citrus peel support reducing plasma liver cholesterol, total serum cholesterol, serum triglyceride levels, and total liver lipids [ 43 ]. Citrus pulp, peel are rich sources of flavonoids.
Toh et al. Makni et al. Citrus fruits are also rich in flavonoids such as hesperidin, hesperetin, naringin, naringenin, diosmin, quercetin, rutin, nobiletin, tangeretin, and others [ 45 ]. Citrus flavonoids have both antioxidant and anti-inflammatory properties, and because of that, it can increase the antioxidant capacity and effect reducing cholesterol and triglycerides levels and provide more excellent bone health [ 22 ].
Over the years, naringin and hesperidin are gaining attention for their great antioxidant capacity, contributing sweet flavor to foods and beverages [ 47 ]. Some known naturally occurring flavonoids have potency in defending against certain types of RNA and DNA viruses [ 48 ]. Limonoids are also known as flavonoids, which are compounds found in citrus fruits. In citrus fruits, there are two groups of limonoids: aglycones and their corresponding glucosides.
Bitter taste in citrus results from limonoids present. In animal and human cell lines, limonoids slow down the development of aggressive cancers like the pancreas, colon, stomach, and breasts. On the other hand, limonoids are also reported to reduce skin cancer in animal models.
Limonoids are known for their medicinal or health beneficial effects like anti-cancer, anti-microbial and antimalarial activities [ 49 ]. Limonoids have antibacterial and antiviral effects. Some limonoids are known to stimulate the in vivo production of the detoxifying enzyme glutathione S-transferase in the liver and inhibit the formation of chemically induced tumor cells in the oral cavity, forestomach, small intestine, colon, lung, and skin of animals [ 50 , 51 ].
Limonoids found in citrus fruits decreased the spread of cancer cells in animal studies [ 52 ]. Studies showed that lemon-lime oil in the form of obacunone appeared to prevent breast cancer by inhibiting aromatase enzyme and anti-inflammatory pathways [ 53 ] Figure 2. Several studies have revealed that limonin and nomilin are found in fruits, pulp, and seeds. Pummelo juice contained 18 ppm of limonin and 29 ppm of total limonoid glucosides [ 54 ]. Wattanasiritham et al. Limonin levels in extracted juice from seven pummelo cultivars from Florida ranged from The mature seeds contain much higher amounts of glucosides than commercialized juice, therefore.
Fong et al. Proposed model for signaling pathways leading to growth inhibition by obacunone in estrogen-responsive breast cancer MCF-7 cells [ 53 ]. Citrus fruits are known for being highly fragrant, with a tart taste and higher vitamin C content. The world has a wider variety of citrus fruit because of the continued type changes, such as sour oranges, oranges, pummelos, lemons, and limes, among others [ 22 ]. These noodles can satisfy those with regular diabetes and the general public [ 21 ].
Lemon fruit is usually eaten fresh, but it is also processed to make juices, jams, jellies, molasses, candies and much more [ 18 ]. As an excellent source of the antioxidant vitamin C, oranges may help combat the formation of free radicals that cause cancer. Although an adequate vitamin C intake is necessary and very beneficial, the amount a person would need for the desired therapeutic effect on cancer is more than they could realistically consume.
For example, one study concluded that medical scientists could harness the power of vitamin C from oranges to inhibit colorectal cancer cells in the future. That said, in , a study linked grapefruit and orange juice with a higher risk of skin cancer.
Researchers found that people who consumed high amounts of whole grapefruit or orange juice were over a third more likely to develop melanoma than those who consumed low amounts.
This may have been due to citrus compounds that exert photocarcinogen properties. Learn more about the powerful health benefits of vitamin C here. Oranges contain no sodium, which helps keep a person below their daily limit.
Maintaining a low sodium intake is essential to lowering blood pressure. According to the Office of Dietary Supplements ODS , increasing potassium intake can reduce the risk of high blood pressure and stroke.
According to one review of previous meta-analyses, consuming enough fiber can significantly reduce the risk of heart disease both developing and being fatal. The review links this effect to its ability to lower cholesterol levels in the blood. The ODS found that people with higher potassium intakes may have a lower risk of stroke and other cardiovascular diseases. They mainly attribute this to the effects of potassium on blood pressure.
A medium orange weighing grams g contributes 3. Several studies have found that fiber can improve some factors that contribute to diabetes development and progression.
For example, one study found that consuming 4 g of a dietary fiber supplement per day did not reduce blood glucose but improved how the body responds to insulin. Low insulin sensitivity can contribute to type 2 diabetes.
Weight control is also important for reducing the risk of diabetes, as obesity and overweight can contribute to the development of type 2 diabetes. The body processes fiber more slowly than other nutrients, so it can help a person feel fuller for longer and reduce their urge to eat snacks throughout the day.
Following a diet that contains a high proportion of fruits and vegetables can support blood sugar control and reduce the risk of type 2 diabetes and disease progression. That said, a diabetes friendly diet should include healthful foods from a variety of food groups. Learn more about the best fruits for people with diabetes here. Consuming enough vitamin C can help a person maintain skin health and appearance.
