WHAT HAPPENS TO YOUR GUT HEALTH WHEN YOU EAT PASSION FRUIT REGULARLY

Medically reviewed by Suzanne Fisher, RD

Key Takeaways

• Passion fruit contains soluble and insoluble fiber, promoting smoother digestion and acting as a prebiotic to feed a healthy gut microbiome.
• Due to the high fiber content, one serving of passion fruit is low on the glycemic index, meaning that it won’t lead to sharp spikes in blood sugar levels.
• Passion fruit is low-FODMAP, making it a gut-friendly fruit option for people living with irritable bowel syndrome (IBS) or other digestive conditions managed through a low-FODMAP diet.

Passion fruit contains a significant amount of vitamins, minerals, fiber, and other beneficial compounds in a small package. The digestive benefits of passion fruit include supporting digestion, the gut microbiome, and being an option for a low-FODMAP eating plan.

How Does Passion Fruit Benefit Gut Function?

Fiber is key to several health benefits inside and outside of the digestive system. Most adults in the United States do not get enough fiber in their diet. Passion fruit are fiber powerhouses, considering their small size. One passion fruit contains 2 grams of fiber, and 1 cup contains 25 grams.

The passion fruit pulp contains soluble fiber, and the seeds contain insoluble fiber.

• Soluble fiber dissolves in liquid and creates a gel that helps stool move along the digestive tract.
• Insoluble fiber goes through the intestines without being fully digested and makes stool bulkier.

Dietary fiber is important in helping prevent constipation by keeping stool soft. Eating enough fiber also helps with diarrhea by keeping stool bulkier. Other health benefits of fiber include:

• Feeling full after eating
• Lowering cholesterol levels
• Nourishing and supporting the gut microbiome (the community of microbes in the gut)
• Reduced risk of colon cancer

Microbiome Support

The fiber in passion fruits also acts as a prebiotic. Prebiotic fiber becomes food for the bacteria and other organisms that live in the gut and make up the gut microbiome. A healthy microbiome is sustained through eating a variety of fiber- and probiotic- rich foods.

A well-fed, diverse microbiome:

• Improves digestion
• Reduces inflammation
• Strengthens the immune system
• Supports metabolism

Low FODMAP-Diet Friendly

FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) types of carbohydrates found naturally in many foods. Some people find that foods containing FODMAPs set off gastrointestinal symptoms.

People sensitive to FODMAPs may experience:

• Abdominal pain
• Bloating
• Constipation
• Diarrhea
• Gas (flatulence)

A low-FODMAP diet is sometimes recommended for people who live with irritable bowel syndrome (IBS). In this diet, foods containing FODMAPs are avoided for a period of time, and then reintroduced slowly.

A serving that includes two passion fruits is a low-FODMAP food.

Effect on Blood Sugar

Passion fruit is high in fiber for its size, which makes it a food that doesn’t spike blood sugar levels:

• Glycemic index is the measure, between 0 and 100, of how quickly a food raises blood sugar levels. Passion fruit has a glycemic index of 30, making it a low glycemic food.
• Glycemic load is the glycemic index of a food paired with the serving size. A passion fruit has a glycemic load of 4, which is also low. The high fiber content of a passion fruit helps slow the digestion of the sugar and carbohydrates it contains.

What’s in Passion Fruit?

Passion fruit contains several vitamins and nutrients, including antioxidants, calcium, folate, iron, magnesium, potassium, vitamin A, and vitamin C. It also contains both soluble and insoluble fiber.

Antioxidants have benefits for overall health by combating free radicals. Free radicals are compounds that the body produces naturally and which cause DNA damage. Antioxidants stabilize free radicals and stop this damage process.

Vitamin C is important to supporting the immune system. Eating vitamin C-rich foods helps the body improve its ability to fight the germs that cause illness and infection. In addition, vitamin C is part of the process by which the body reduces inflammation. 

One passion fruit (about 18 grams) contains:

• Calories: 17.5 kilocalories (kcal)
• Calcium: 2 milligrams (mg)
• Carbohydrate: 4.2 grams (g)
• Fiber: 2 g
• Folate: 2.5 micrograms (mcg)
• Iron: 0.3 mg
• Magnesium: 5 mg
• Potassium: 63 mg
• Protein: 0.4 g
• Sugars: 2 g
• Vitamin A: 11.5 mcg
• Vitamin C: 5.4 mg

How to Eat Passionfruit

The flesh (pulp) and seeds of a passion fruit are the edible parts. To eat a passion fruit, wash the outside, cut it in half, scoop out the pulp and seeds, and discard the rind.

Eat passion fruit as is, or add a sweetener such as sugar or honey to reduce its tart flavor. Spoon it over yogurt, oatmeal, or desserts. Passion fruit is also served mixed into a fruit salad or blended into a smoothie.
