10 Ordinary Fruits With Amazing Health Benefits

Grapefruit in your diet may decrease your risk of insulin resistance, a precursor to type 2 diabetes, according to research. When overweight adults ate a half grapefruit, drank grapefruit juice, took a grapefruit pill, or took a placebo once a day before a meal for 12 weeks, those who consumed grapefruit in any form had lower insulin levels (higher levels are a sign of type 2 diabetes). What’s more, the fresh grapefruit eaters lost an average of 3.5 pounds more over the course of the study than the placebo group. (But if you take any medications, talk to your doctor first, as grapefruit can interact with many different drugs, according to the U.S. Food and Drug Administration.)

One reason for grapefruit’s potential health perks? It contains a compound called naringenin that’s also found in other citrus fruits, and accordin to a research review, it may provide anti-inflammatory benefits and protect against cardiovascular disease. This compound may also help prevent kidney cysts, per in vitro and animal research.

To put your grapefruit to use, you can have one as your morning meal, but also consider using grapefruit as a compliment to a seafood dish, or even add some wedges to your morning smoothie. One-half grapefruit contains nearly 2 grams (g) of fiber, according to the U.S. Department of Agriculture (USDA). And of course, grapefruit shines when it comes to its vitamin C content — the same serving has 38.4 milligrams (mg) of vitamin C, according to the USDA.

Blueberries help keep your body healthy and your mind sharp — research has linked blueberries to improved memory and learning, thanks in part to the anti-inflammatory effects of anthocyanins, which are the antioxidants that give the fruit its deep blue and purple hue. Another study found that when older adults with early stages of cognitive decline took blueberry supplements, they experienced neurocognitive benefits.

Last but not least, research found that participants who ate 1 cup of blueberries each day lowered their odds of developing cardiovascular disease by up to 15 percent. Now, that’s a reason to stock up!

“In addition to the health benefits of blueberries, they shouldn’t be overlooked, because they taste great and are very versatile in the kitchen,” says Levinson. “Whether you throw some on top of cereal or yogurt for breakfast, add them to a salad for lunch, turn them into sauces and dressings, use them to make mocktails and cocktails, or use them to make dessert, there are endless ways to enjoy blueberries!”

In two-thirds cup, you get 64 calories and 86 mg of potassium, according to the USDA.

“That old saying ‘an apple a day keeps the doctor away’ might just have been on to something,” says Maggie Michalczyk, RD, the Chicago-based founder of Once Upon a Pumpkin.

When overweight, post-menopausal women ate around a cup of dried apples each day for a year, they experienced an almost 6 percent drop in “bad” LDL cholesterol, according to a study. What’s more, the women’s “good” HDL cholesterol increased by about 10 percent, and they lost an average of 2.4 percent of their body fat.

The heart-healthy benefit may stem from the apples’ pectin (a type of fiber) and polyphenols (a group of antioxidants), according to the Harvard T.H. Chan School of Public Health.

Other research has found that apples may also protect against chronic obstructive pulmonary disease (COPD), possibly due to their high level of flavonoid antioxidants.

“Apples are a good source of many nutrients — notably fiber, which supports heart health and may help with weight loss,” says Malkani. According to the USDA, a medium apple has a whopping 4.8 g of fiber, making it a good source. You also score a notable amount of vitamin C — 9.2 mg, according to the USDA.

Obviously, apples make for a great snack, but you can also bake with apples or even make your own applesauce.

A flavonoid in this citrus fruit may protect the body against the group of risk factors known as metabolic syndrome, which includes high fasting blood sugar, high triglyceride levels, and high blood pressure, according to research on animals. When researchers fed mice a typical “Western” diet high in saturated fat, sodium, added sugar, and refined carbohydrates that was supplemented with the tangerine antioxidant nobiletin, the mice experienced no increase in cholesterol, triglycerides, insulin, or blood sugar; but mice who didn’t get the nobiletin did see a rise.

Other research on animals has found that the compound may prevent atherosclerosis, which is the hardening of the arteries that can increase the risk of heart attack and stroke, the Mayo Clinic explains.

Interestingly, tangerine peels may play a role in helping to prevent certain types of cancer. A compound in the peel called salvestrol Q40 halts the activity of an enzyme that incites the growth of cancer cells, research has found. Try some tangerine zest in your tea or sprinkled on a salad for a citrusy twist.

One medium-size tangerine has 1.6 g of fiber, according to the USDA, providing you with nearly 6 percent of your daily value (DV), plus over 23 mg of vitamin C, which is 26 percent of your DV, making it an excellent source.

According to one study, when 36 people with precancerous esophageal lesions ate 2 ounces (oz) of freeze-dried strawberries daily for six months, 80 percent saw a decrease in the severity of the lesions. The researchers aren’t sure which of the vitamins, minerals, or other nutrients in the berries are responsible, but they plan to investigate the possibility that strawberries may be valuable as an add-on or alternative treatment to cancer-treating drugs. Note that the study was small and funded by industry — the California Strawberry Commission — so the results may be skewed.

Strawberries — as well as other berries — might also protect you against skin cancer, bladder cancer, lung cancer, and breast cancer, according to MD Anderson Cancer Center. Yet at this stage, much of the research has been primarily conducted on animals — for example, one study found that strawberry extract stopped the spread of breast cancer cells in mice.

Strawberries also take care of your ticker. A study found that regular strawberry consumption counteracted the inflammatory and blood-clotting effects of a high-fat, high-carbohydrate meal, potentially decreasing the risk of cardiovascular disease. Other research found that women who ate at least three servings of strawberries and blueberries per week had lower odds of heart attack.

“They make for a great snack, and you can use them in a variety of different ways,” says Michalczyk. “Frozen is also a great way to go for things like smoothies,” she adds.

One cup of halved strawberries contains over 3 g of fiber, according to the USDA, which is about 11 percent of your DV, making them a good source. The juicy red berries also come packed with vitamin C: 1 cup of halved strawberries contains over 89 mg of vitamin C, which is 99 percent of your DV.

“People may think prunes are food for the elderly or only worth eating for digestive health, but they are wrong,” says Levinson. “There are lots of great reasons to eat prunes or dried plums.”

For one, they’re bone-friendly. When post-menopausal women ate about five to six dried plums a day for six months, they maintained higher bone mineral density than a control group, according to one study.

“Prunes provide a natural sweetness and add moisture and richness to desserts and baked goods, allowing you to reduce the amount of butter, sugar, and oil you would otherwise use,” says Levinson. “They also pair well with a variety of other flavors and can be used for both sweet and savory dishes.”

A ½ cup serving of dried, pitted prunes has nearly 6 g of fiber, according to the USDA.

Meanwhile, prunes contain 366 mg of potassium per ½ cup without pits. The American Heart Association notes that adequate potassium in your diet helps you manage high blood pressure. Potassium also helps with kidney and muscle function, according to the National Institutes of Health (NIH).

Think out of the can when it comes to these tart fruits.

Antioxidants called proanthocyanidins in cranberries can halt the activity of bacteria that cause dental cavities, supporting regular dental hygiene habits, according to a review of research. To reap this potential perk, opt for the whole fruit, not the jellied variety, which contains a whopping 22.5 g of sugar per ¼ cup, per the USDA.

To enjoy fresh, whole cranberries, try simmering up your own subtly sweet relish instead, or toss a handful in your sparkling water, then eat them afterward.

Fresh cranberries come with almost 4 g of fiber per cup when chopped, according to the USDA, for 14 percent of your DV, making them a good source. The same serving has only 5 g of sugar. Plus, you score over 15 mg of vitamin C in each cup, which is 17 percent of your DV, making it another good source.

Polyphenol-rich grapes can reduce inflammation that contributes to a variety of health problems, including type 2 diabetes, atherosclerosis, and high blood pressure, research suggests. And long-term, chronic inflammation is associated with conditions including heart disease, diabetes, cancer, and arthritis, notes Harvard Health Publishing.

The fruits may fight inflammation in several ways, including acting as antioxidants, reducing cell oxidative stress, and blocking pro-inflammatory compounds called cytokines, noted one research review.

According to Mayo Clinic, antioxidants are compounds found in plants, including grapes, that help your body fight free radicals, which are molecules your body accumulates when exposed to harmful substances, such as tobacco smoke and radiation. Too many free radicals can cause oxidative stress, per Mayo Clinic, which is connected to various diseases like heart disease, diabetes, and Alzheimer’s.

Red grapes may even protect against everyday ailments like the common cold. Similar to blueberries, red grapes contain the compound resveratrol, according to research. This compound is an immune system supporter, but it has also been linked in large doses to heart health and prevention of certain types of cancers. Nevertheless, Memorial Sloan Kettering notes that most of the research has been animal studies, and human studies have not established a real benefit.

“Grapes can be enjoyed — as they most often are — as a snack, but they can also be put to great use in the kitchen,” says Levinson. “They can be used to make sauces, dressings, and marinades, they are delicious roasted and added to grain salads or baked with meat, chicken, or fish, or enjoyed in salads, side dishes, and desserts,” she says.

Each two-third cup serving of seedless grapes scores you 229 mg of potassium, notes the USDA. Not too shabby!

“Bananas offer antioxidants, fiber, and many essential nutrients, such as vitamin B6, but what makes them especially interesting is that their nutrient content changes depending on their level of ripeness,” says Malkani. “Underripe bananas contain a lot of resistant starch, which helps reduce appetite and may stabilize blood sugar levels after meals by slowing the rate of stomach emptying,” Malkani adds, and Johns Hopkins concurs.

One slightly ripe banana has more than 5 g of fiber, according to the USDA. Also, bananas are renowned for their potassium — the same slightly ripe banana has 375 mg of potassium, the USDA notes. You’ll also get more than 14 mg of vitamin C and 0.2 mg of vitamin B6, too, the latter of which will support your immune system and metabolism, according to the NIH.

“In my opinion, bananas should be a grocery staple because they are versatile and nutritious and make for a great snack or addition to many meals — hello, everyone’s favorite, banana bread!” says Michalczyk.

You’ve seen pears stocked in the produce aisle at your grocery store and passed them by, but it’s time to pick some up. It might be an especially good idea if your digestion is out of whack.

That’s because pears are full of fiber. For example, one medium pear is packed with more than 5.5 g of fiber, according to the USDA, which is 20 percent of your DV, making it an excellent source. And why that matters: Dietary fiber (the kind you consume through food) impacts your gut’s ecosystem, according to a review of research.

Also, as Mayo Clinic notes, fiber helps your digestive system function properly, and pears are one of the top fruit sources of this nutrient. Add pears to your next salad or yogurt bowl, or even simply bake a pear with cinnamon on top. Delicious!

Just know that all fruits (and vegetables) are good choices when it comes to your gut — and your health. “Americans don’t consume enough fruits and vegetables as it is, so any and all consumption of fruit — no matter what kind — is beneficial,” says Levinson.
