\u201cAn apple a day keeps the doctor away\u201d is a centuries-old proverb, but is there any truth to it? It\u2019s no secret that there are health benefits of apples. These round, colorful fruits were used in traditional medicine for their myriad of nutrients and beneficial properties, such as<\/span> aiding digestion<\/span><\/a> and fending off disease. Today, many Americans still enjoy snacking on an apple at lunch or in between meals. Apples are portable, making them a convenient and tasty source of nutrients. Here are some of the top benefits of eating apples.<\/span><\/p>\n

8 health benefits of apples<\/span><\/h2>\n

Eating plenty of fruits and vegetables is an important part of maintaining a balanced diet. Apples are a popular choice because of their pleasant taste and texture. They\u2019re also rich in a variety of nutrients, such as antioxidants and fiber, which are responsible for their many health benefits. Adding apples to your diet may:<\/span><\/p>\n

1. Provide disease-fighting antioxidants<\/span><\/h3>\n

Apples are colorful fruits, and the pigments that give them their hue also provide antioxidant benefits. \u201cApples are high in a type of antioxidants called polyphenols,\u201d explains<\/span> Jenna Volpe, RDN<\/span>, a registered dietitian and the owner of Whole-istic Living in Austin, Texas. \u201cPolyphenols are chemicals found in fruits and vegetables that scavenge free radicals, harmful substances that can cause cell damage and aging.\u201d<\/span><\/p>\n

When left unchecked, these unstable free radical molecules cause oxidative stress.<\/span> Research shows<\/span><\/a> that oxidative stress can contribute to the progression of various chronic conditions, such as heart disease and cancer. Antioxidants can counteract the harmful effects of free radicals on human health.<\/span><\/p>\n

While there are several antioxidant polyphenols in apples, there\u2019s a potent one to note in red varieties of apples. \u201cQuercetin is found in red apple peels,\u201d Volpe says. \u201cIt\u2019s an antioxidant that\u2019s shown to help reduce inflammation and support immunity.\u201d<\/span><\/p>\n

Quercetin<\/span> has been identified<\/span><\/a> as the most potent antioxidant found in red apple skin and flesh. In addition to having strong antioxidant properties, quercetin<\/span> has also been shown<\/span><\/a> to reduce inflammation, support cardiovascular health, and possess anti-cancer properties.<\/span><\/p>\n

2. High in dietary fiber<\/span><\/h3>\n

One of the most well-known health benefits of apples is related to the digestive tract: Apples are high in dietary fiber. \u201cOne apple contains about 4 grams of dietary fiber, which can help support healthy bacterial growth in our gut,\u201d says<\/span> Nicole Ibarra, RD<\/span><\/a>, a registered dietitian and the founder of Altitude Nutrition & Fitness.<\/span><\/p>\n

Fiber plays a critical role in healthy digestion. \u201cThe fiber in apples feeds the gut microbiome, which can lower inflammation, improve insulin sensitivity, and support a healthy metabolism,\u201d explains<\/span> William Li, MD<\/span><\/a>, a physician and the author of <\/span>Eat to Beat Disease<\/span><\/i>. It\u2019s also helpful for<\/span> preventing and <\/span>alleviating constipation<\/span><\/a>.<\/span><\/p>\n

Despite the importance of eating enough fiber, most Americans aren\u2019t. An<\/span> estimated 95%<\/span><\/a> of Americans are lacking fiber in their diets. The average person needs about<\/span> 28 grams of fiber<\/span><\/a> per day, and one apple can provide 14% of your Daily Value (DV) for fiber.<\/span><\/p>\n

There\u2019s just one caveat about the fiber in apples\u2014not everyone can tolerate them. \u201cApples are a high-FODMAP food, so they can cause bloating or gas in people with irritable bowel syndrome (IBS),\u201d Ibarra explains.<\/span><\/p>\n

3. Contain gut-friendly prebiotics<\/span><\/h3>\n

The fiber in apples can support gut health, which can be partially chalked up to the high levels of prebiotics in apples. Prebiotics are a type of fiber that feeds the good bacteria in your gut microbiome.<\/span><\/p>\n

\u201cApples are a natural food source of a prebiotic soluble fiber called pectin,\u201d says Volpe. \u201cIt\u2019s fuel for probiotics, the healthy microbes that live mostly in our gut.\u201d<\/span><\/p>\n

Pectin accounts for the majority of the soluble fiber in apples and<\/span> has been linked<\/span><\/a> to some gut health benefits, including anti-inflammatory effects. The pectin in apples can increase levels of beneficial bacteria while reducing harmful bacteria in the gut.<\/span><\/p>\n

4. Assist with weight loss<\/span><\/h3>\n

Apples have several properties that could contribute to weight loss. According to<\/span> USDA data<\/span><\/a>, one medium apple (200 grams) provides 122 calories and 4.2 grams of fiber, making apples low in calories yet high in fiber. Reducing your caloric intake by choosing low-calorie foods, such as apples, can promote healthy weight loss. It\u2019s also important to get plenty of fiber. In<\/span> one systematic review<\/span><\/a>, dietary fiber was shown to significantly improve body weight in people with overweight, diabetes, or metabolic syndrome.<\/span><\/p>\n

Apples also contain a bioactive called chlorogenic acid, found in both apple peels and flesh, which may be beneficial for weight loss. \u201cThis naturally occurring chemical has anti-inflammatory effects and can improve metabolism by helping to burn down harmful excess body fat,\u201d Dr. Li says.<\/span><\/p>\n

Dr. Li highlights another compound in apples: ursolic acid. <\/span>Studies show<\/span><\/a> ursolic acid has many benefits, including anti-obesity effects. Overall, apples have been linked to weight loss in both human and animal studies,<\/span> one review<\/span><\/a> notes.<\/span><\/p>\n

5. Help lower cancer risk<\/span><\/h3>\n

Cancer is a leading cause of death worldwide. The relationship between what you eat and cancer prevention is complicated, and more research is needed. However, certain dietary patterns could reduce the risk of types of cancer. According to the<\/span> American Cancer Society<\/span><\/a>, a diet rich in fruits and vegetables may reduce your risk of developing certain types of cancer.<\/span><\/p>\n

In other words, apple consumption could contribute to cancer prevention. \u201cResearch has shown that apples may help prevent certain types of cancer, including lung cancer, stomach cancer, oral cavity cancer, colon cancer, and esophageal cancer,\u201d Volpe explains, pointing to a<\/span> comprehensive review<\/span><\/a> and another<\/span> study<\/span><\/a>.<\/span><\/p>\n

Apples may have potential anti-cancer effects due to the multitude of <\/span>antioxidants<\/span><\/a> and fibers they contain. The antioxidants help reduce oxidative damage (which precedes cancer), while prebiotic fibers help optimize the gut microbiota, Volpe says.<\/span><\/p>\n

6. Prevent chronic diseases<\/span><\/h3>\n

In addition to playing a part in preventing obesity and certain types of cancer, apples may help prevent other chronic diseases. According to Dr. Li, this is partially explained by the high levels of ursolic acid in apples.<\/span><\/p>\n

Ursolic acid is a beneficial compound found in many fruits and vegetables, including apples.<\/span> The benefits have mainly been shown in animal studies, rather than human studies, so more research needs to be done to know more about its effects. <\/span>One review<\/span><\/a> found that ursolic acid lowers inflammation and may have preventive effects on cardiovascular diseases.<\/span> Ursolic acid may also promote brain health. Some<\/span> animal studies<\/span><\/a> have found potential neuroprotective effects of ursolic acid, which suggests it may help prevent diseases like Alzheimer\u2019s disease, but again, more research on humans is needed to determine the effects.<\/span><\/p>\n

Ursolic acid works by improving blood flow, Dr. Li says. This is significant because compromised blood flow is associated with several chronic diseases, including <\/span>Type 2 diabetes<\/span><\/a> and atherosclerosis (a buildup of plaque in the arteries, which can lead to heart disease).<\/span><\/p>\n

Red Delicious and Royal Gala apples<\/span><\/a> have the highest ursolic acid content, which increases their potential antioxidant and disease-fighting properties.<\/span><\/p>\n

7. Rich in potassium<\/span><\/h3>\n

Apples are known for their high fiber content, but they\u2019re also a good source of other micronutrients, such as <\/span>potassium<\/span><\/a>. \u201cMost Americans don\u2019t get enough potassium in their diets, but the mineral is helpful for muscle contractions, maintaining a healthy blood pressure level, and fluid balance,\u201d Ibarra says. One way to<\/span> increase your intake of potassium<\/span><\/a> is to eat more apples, she adds.<\/span><\/p>\n

One medium apple (200 grams) provides more than<\/span> 200 milligrams<\/span><\/a> of potassium. Adults need between<\/span> 2,600 mg and 3,400 mg<\/span><\/a> of potassium per day, so one apple could account for up to almost 8% of your DV for potassium.<\/span><\/p>\n

8. Support cardiovascular health<\/span><\/h3>\n

Apples are known for their heart health benefits, which is largely due to the high amounts of fiber. \u201cFiber works like a ship transporting containers away from the dock, which is a metaphor for<\/span> removing cholesterol<\/span><\/a>,\u201d Ibara says. The nutrient helps reduce \u201cbad\u201d LDL cholesterol, which can lower the risk of stroke and heart disease.<\/span><\/p>\n

Can eating an apple a day keep the heart doctor away? Maybe. In<\/span> one review<\/span><\/a> of observational studies, eating at least 100 grams of apples (about half of a medium-sized apple) per day was associated with less inflammation, lower blood pressure and total cholesterol levels, and a lower cardiovascular disease risk.<\/span><\/p>\n
