12 Best Low Carb Fruits

What fruits are low in carbs?

Despite the misconception, fruit is not just a huge pile of fructose, and they are foods which offer various benefits. And some of them are incredibly nutritious and beneficial for our health.

Providing you are sensible, you can eat fruit on low carb and even keto diets. Here is a list of the best low carb fruits for health, together with their nutrient profile, and health benefits. To make it a fair comparison, you can see the carb count per portion, as well as net carbs per 100g.

1. Avocado

12 Best Low Carb Fruits

Despite people often believing it to be a vegetable, avocado is probably unrivaled as a low carb fruit. The reason is that it supplies a huge amount of healthy fat rather than fructose.

It is also delicious, works well with almost any food combination, and it is the key ingredient in Mexican staple guacamole.

Health Benefits of Avocados

  • Avocados are extremely nutrient-dense and contain a wealth of vitamins and minerals. Consumption helps improve blood lipid profiles, enhances the bio-availability of vitamins and minerals, and clinical studies show they may help improve cardiovascular health.
  • Avocados reduce the risk of metabolic—and cardiovascular—disease. Also, epidemiology shows a strong association between avocado intake and lower body weight and higher HDL levels.
  • Similar to other fruits, avocados contain a range of bioactive polyphenols that help support optimal health.

Key Point: There are 3.6 grams of net carbs in one avocado – and 1.8 grams per 100g.

2. Blackberries

12 Best Low Carb Fruits

Blackberries are one of my favorite fruits, and they are healthy and tasty, not to mention reasonably low in carbohydrate.

These berries are also full of healthful phytonutrients — especially wild blackberries.

Benefits of Blackberries

  • Studies show that blackberries contain large amounts of antioxidants that protect against free radical damage and result in changes that protect against inflammation in the brain — potentially helping to fight dementia.
  • Both epidemiological and clinical studies show that blackberry intake leads to a decrease in CVD risk factors. Namely, lower blood pressure and blood glucose, and also a better cholesterol profile.
  • Blackberries have a long history of medicinal use. At the present time, blackberries play a role in modern medicine due to various compounds they contain with anticancer, antidiabetic and antimicrobial effects.

Key Point: There are 7.1 grams of net carbs in one cup of blackberries and 4.9 grams per 100g.

3. Blueberries

12 Best Low Carb Fruits

Blueberries are one of the tastiest fruits out there, and they are reasonably low in carbohydrate.

Like other berries, blueberries provide a lot of polyphenols — especially if you can find wild blueberries, which contain significantly more than commercially cultivated berries.

Benefits of Blueberries

  • An 8-week randomized, double-blind, placebo-controlled clinical trial with 48 participants shows that daily blueberry consumption may reduce blood pressure and arterial stiffness. Compared to the control group, the blueberry group had lower levels of inflammation and antioxidants in the blood.
  • In human trials, 12 weeks of daily blueberry supplementation reduced depressive symptoms and glucose levels in older adults. Additionally, those taking the blueberry supplement showed improvements in memory on memory tests.
  • Randomized controlled trials show that bioactive compounds in blueberries such as anthocyanins (an antioxidant) help improve insulin sensitivity in obese adults.

Key Point: There are 17.8 grams of net carbs per cup of blueberries – 12.1 grams per 100g.

4. Coconut

12 Best Low Carb Fruits

Coconuts are somewhat of a flagship low carbohydrate fruit due to all the ways you can use them;

  • Coconut oil
  • Coconut milk
  • Creamed coconut bars
  • Coconut chips
  • Coconut butter

…. and the list goes on.

Coconuts are very useful for making various low carb snacks too.

Coconut Health Benefits

  • In a study of 60 free-living, healthy participants consumed coconut milk for 5 days per week over 8 weeks. The result was a decrease in LDL levels and a significant rise in HDL levels – therefore having a beneficial health impact.
  • Coconuts contain a large number of medium chain triglycerides (MCTs) that are used by the body to produce energy quickly. Besides this, coconut fats are very heat-stable due to their high degree of saturation.

Key Point: Coconuts contain 5 grams of net carbs in a cup serving and 6.25 grams per 100g.

5. Cantaloupe

12 Best Low Carb Fruits

Cantaloupe is a kind of muskmelon, and they are native to both Europe and North America. Although they have a very similar profile to honeydew melons, they are a little different.

Despite their sweet and succulent taste, cantaloupes are one of the top low carb fruits and only contain minimal carbs.

Beneficial Properties of Cantaloupes

  • Cantaloupes are extremely high in vitamin A, which helps maintain and protect eyesight.
  • Cantaloupe is one of the most significant dietary sources of vitamin C, which plays a major role in immune health.

Key Point: Cantaloupes contain 8 grams of net carbs in one medium size wedge (approximately 100g).

6. Gooseberry

12 Best Low Carb Fruits

To be honest, I have a hard time eating gooseberries — they are just so extremely sour! However, gooseberries are one of the best low carb fruits and contain minimal sugar.

Health Benefits of Gooseberries

  • Gooseberries contain a vast amount of polyphenols, and clinical studies show that their extracts have anticancer properties. A concentrated extract is not the same as eating the fruit, but it does show that they contain beneficial compounds.
  • The gooseberry is a decent source of the class of compounds known as anthocyanins. These compounds help fight free radicals and offer anti-inflammatory benefits.

Key Point: Gooseberries contain 8.9 grams of net carbs per cup and 5.9 grams per 100g.

7. Grapefruit

12 Best Low Carb Fruits

Slightly sour tasting, grapefruits are a low sugar fruit with a reasonably low carb count.

There are all sorts of ways to eat grapefruit, such as putting a few slices in hot water to make grapefruit tea. Eating grapefruit just in its natural state is also great.

Health Benefits of Grapefruit

  • Grapefruits contain a significant amount of vitamin C; just 50 calories of grapefruit provides 64% of the RDA.
  • A range of studies suggests that grapefruit may help lower postprandial plasma glucose and improve insulin sensitivity.

Key Point: There are approximately 11.1g of net carbs per half of a grapefruit. With a net carb count of 9.1 grams per 100g, grapefruit is one of the reasonably low carb fruits.

8. Lemon

12 Best Low Carb Fruits

Lemons are a native species of fruit to Asia, and they are among the fruits lowest in carbs.

The sugar content in lemons is relatively small, and they can have a very sour taste!

Lemon Health Benefits

  • Similar to other citrus fruits, lemon contains a good amount of vitamin C.
  • An epidemiological study on middle-aged and senior women shows that there was a significant decrease in blood pressure with increasing lemon intake.
  • Animal studies suggest that the antioxidative polyphenols found in lemons show promise by helping suppress body fat accumulation.

Key Point: One lemon has 3 grams of net carbs, while 100g provides around 6 grams of net carbohydrate.

9. Lime

12 Best Low Carb Fruits

Sharing similar properties to lemon, lime is also one of the lowest carb fruits.

Limes are a hybrid citrus fruit which has a very slight amount of sugar, but a lot of acid. As a result, they are only mildly sweet and have an intensely sour taste.

Positive Health Effects

  • Interestingly, controlled animal studies show that concentrated lime juice and lime peel helped prevent atherogenesis (plaque in the arteries). This effect was significantly more powerful in the study group fed on the lime peel, suggesting a higher concentration of polyphenols.
  • Limes contain a broad range of polyphenols and acids that have high antimicrobial activity.

Key Point: There are 5.2 grams of net carbs in one lime. The number of net carbs per 100g is 7.7g, which makes lime one of the lowest carb fruits.

10. Lingonberry

12 Best Low Carb Fruits

Lingonberries are one of the lesser known low carb fruits, but they are a great food to eat on a low carb diet.

Lingonberries grow both in the wild and domesticated, appearing on short shrubs. They also have the rather unusual nickname of “cowberries.”

Health Benefits

  • Lingonberries alter the gut microbiota and help prevent low-grade inflammation and obesity.
  • In rats fed an unhealthy obesogenic diet, animals who supplemented with lingonberry daily experienced significantly less weight gain.

Key Point: The total net carbohydrate comes to 7.8 grams in lingonberries.

11. Olive
