Which Fruits are More Unhealthy Than They are Healthy?

An apple a day keeps the doctor away, as the saying goes, but some fruits might as well be hidden sugar mines. Sugar is in everything, but there are plenty of reasons to avoid sugar as well. So the idea of unhealthy fruit seems like nature's evil joke, tricking us into thinking we're being healthy when really we're downing tablespoons of sugar. Forbidden fruit, it seems, is a plausible concept.В

Before swearing off the fruitВ section of the grocery store for good, take noteВ thatВ only a few are high glycemic: "It's important to consume a variety of fruits and vegetables for optimal health, but some fruits are dense with sugar and lack fiber," says Paula Simpson, RNCP. "These types of fruits are considered 'high glycemic,' meaning they are rapidly digested, causing quick spikes in blood sugar and insulin levels. This hill-and-valley response can increase risks for insulin resistance, lethargy, sugar cravings (due to unbalanced blood sugar levels), and weight gain over the long term."В

Meet the Expert

Paula Simpson, RNCP, is a holistic nutritionist and founder of Zea Skin Solutions. she has consulted for several skincare brands, has written her first book Good Bacteria for Healthy Skin, and is featured in publications like Allure and InStyle.

All nutritionists we surveyed agreed that berries and apples are theВ best fruits: one raspberry or blueberry has roughly one calorie, and apples and berries (blackberries, blueberries, raspberries, cranberries) have high fiber content, which ticks off the boxesВ for optimal digestion and healthy blood glucose levels.

But below, you can, take a look at the most sugar-laden fruits.

Simpson says that lychees haveВ 29 grams of sugarВ in one cup, which is more than a can of Red Bull, but only two and a half grams of fiber. Fruits that provide less than two and a halfВ grams of fiber per serving are considered low in fiber.

According to nutritionist Jenny Champion, MS, RD, CDE, "Perhaps mangos are synonymous with tropical vacations (and splurging!) for a reason: one cup has almostВ 23 grams of sugar-the same as a bag of Sour Patch Kids."

Bananas are a great grab-and-go option when you're feeling healthy, but in reality, they're alsoВ 25% sugar.В Lisa Moskovitz, RD, CDN, says that while they're a good source of potassium and other micronutrients, "there are many otherВ fruitsВ that offer so much more, such as blueberries and raspberries." They're not bad for you, but you shouldn't be using them as a meal replacement very often.

According to Simpson, one small fig hasВ eight grams of sugarВ and only one gram of fiber-which means they might be great on a charcuterie board, but maybe not so great for our blood glucose levels. Moderation.

Brooke Alpert, MS, RD, CDN, says that it's easy to overeat cherries, and atВ 18 grams of sugar in one cup, that can add up quickly.В

We preferВ our grapes in wine form, but popping them as a snack seems healthy enough. According to Champion, though, "The suggested serving size for grapes is 17 of them. When is the last time you stopped at 17 grapes? Exactly. The other problem? They're not doing your daily fiber goals any favors with less than one gram per serving." Turns out, one cup of grapes hasВ 15 grams of sugar-yikes.

Maria Bella, MS, RD, CDN, founder ofВ Top Balance Nutrition, says pineapple is high in sugar (16 grams in one cup, to be exact) and calories, but it also has manganese, which helps control blood sugar. In other words, pineapple is a bit of a give-and-take, so it's best to limit your servings, but of all the things on this list, it's probably the best.В



Fat content can also be an issue with fruits. Says Bella, "Not too many people think of coconut as a fruit, but it is a fruit of the coconut palm tree. Coconut flesh is very high in calories and fat. I would be cautious with the amount consumed, especially if you are watching your weight." Luckily, you don't often see people eating coconut as more than a garnish.

Keeping this all in mind, know that sugar-heavy fruits aren't the enemy. It's all about moderation. Plus, they still provide vital nutrients and necessary carbs that don't make them as abysmal as, say, a can of soda or a piece of candy. Says Bella, "Carbohydrates are an important part of our diet-especially those of us who are highly active. A cup of pineapple with a cup of kefir or reduced-fat yogurt or one slice of whole-wheat bread topped with natural peanut butter and half a banana can make a good pre-workout snack.В

"In order toВ get all theВ benefits without overdoing it on calories and carbs,В mix and match the types of fruitsВ you consume and spread out your fruit intake throughout the day, always pairing it with aВ source of protein and healthy fat (which curb hunger), and try to have six colors of total produce daily, shifting the focus on abundance instead of restriction."

And now, for some of the healthiest fruits.



WeВ polled several dietitians who agreed that blueberries are the best fruit, nutritionally speaking. They're loaded with over 15 potent antioxidants that help protect several areas of our bodies, like our brains and our skin. They're also low in calories, but high in fiber, which is especially helpful if you're looking to shed some excess body fat.


Loaded with vitamin C, lemons help produce collagen and protect the skin from free radicals. Sipping on hot lemon water all day will alsoВ improve your digestion, as well as increase good cholesterol levels.

Next up, this is theВ unhealthiest vegetable you can eat, accordingВ to Harvard scientists.
