Interested in incorporating citrus fruits into your eating routine? Here’s what could happen to your body.

1. You’ll Get a Solid Dose of Fiber

Adults need about 25-38 grams of fiber daily (or 14 grams per 1,000 calories), and citrus fruits can help you meet this goal.1 One orange provides 2.3 grams of fiber, while a large tangerine has 2.1 grams.23

Most of this fiber is pectin, a type of soluble fiber.4 Soluble fiber forms a gel-like substance that helps slow digestion and prevent blood sugar spikes. It also binds to cholesterol to remove it from your body and lower cholesterol levels.5

The remaining fiber is insoluble, which adds bulk to your stool and regulates your bowel movements.

2. You May Get Some Protection Against Heart Disease

Citrus contains flavonoids and vitamin C, which are antioxidants that promote heart health.

Flavonoids help decrease inflammation, while vitamin C may protect against atherosclerosis. This plaque buildup in the artery walls increases the risk of heart attack and stroke.

Citrus fruits are sources of other heart-healthy nutrients, including folate and potassium.9 Folate helps break down homocysteine, an amino acid that can increase heart disease risk when consumed in high levels.10 Meanwhile, the potassium in citrus fruits helps offset the harmful effects of sodium to control blood pressure.11

Some metabolites, or substances your body creates when it breaks down citrus, can also decrease heart disease risk.

3. You May Get Help Absorbing Other Nutrients

Adding citrus fruits to your plate may help you get more out of other foods you eat.

The vitamin C in citrus fruits helps your body absorb iron from plant-based sources.12 Iron is a mineral that supports immune health and helps make red blood cells. 

4. You’ll Get a Hydration Boost

Eating plenty of water-rich foods, including citrus fruits, can keep you hydrated. One small orange is about 87% water, and 1 cup of unsweetened grapefruit juice is 91% water.132

Staying hydrated quenches your thirst and helps your body’s systems work properly. Men need about 125 ounces of water daily, and women need 91 ounces. These amounts include the fluids found in beverages and foods, such as citrus fruits.14

Staying hydrated is essential for overall health. It lubricates your joints, regulates your body temperature, and helps prevent constipation.15

5. Your Colds May Be Shorter

Vitamin C cannot prevent colds, but some evidence suggests it might reduce their duration and severity.16

Six ounces of orange juice has 103% of your recommended Daily Value (DV) for vitamin C. One whole orange has 78%, and one-half of a medium grapefruit has 43%.12

6. Your Skin Might Look Healthier

Vitamin C plays a role in collagen production, which leads some researchers to believe it can help keep skin looking supple and smooth. A 2017 review found that high fruit and vegetable intake can prevent visible signs of aging. The researchers noted that vitamin C may protect your skin against harmful ultraviolet (UV) rays.17

7. You’ll Pack in Potassium

Citrus fruits are rich sources of potassium, which helps regulate fluids and contract your muscles. Potassium counters the amount of sodium in your diet by helping your body flush it out, which helps control blood pressure.

Limiting your sodium intake can help decrease the risk of and treat high blood pressure (hypertension).

Eating plenty of potassium-rich foods can help lower your risk of heart disease and strengthen your bones.18

What To Watch Out For

Citrus fruits come with many benefits and are generally safe to consume. However, there are some things to keep in mind.

First, consider that whole fruit is often better than juice. Whole fruits are more filling for fewer calories than citrus fruit juices. The juicing process also removes a considerable amount of the fiber found in citrus fruits.20 Plus, juices have many calories and added sugars. Drinking too much fruit juice can contribute to weight gain and high blood sugar. If you do have fruit juice, opt for varieties with no added sugar.

Second, keep in mind that grapefruit can interact with medications, including statins (which treat high blood pressure) and anti-anxiety medications. Check with a doctor or pharmacist to rule out any interactions.21
