Passion Fruit Health Benefits and Usage

Passion fruit (Passiflora) is an oval or round-shaped fruit with a waxy and tough rind. The passion fruit comes in two varieties: yellow and purple. It’s loaded with beneficial antioxidants and fiber, making it a nutritious and unique treat enjoyed in many cultures across the globe. The fruit is a blossoming tropical vine that thrives in warm climates, including India, South Africa, Australia, and South America.

Health Benefits

Passion fruit is packed with nutrients and fiber that promote optimal health and helps prevent diseases.

Regulates Blood Pressure

A full cup of the fruit contains 821mg of potassium. This is between 24% and 32% of the daily recommended intake for many adults. Technically, potassium increases the removal of sodium in the urine and this reduces blood pressure.

Also, potassium improves vasodilation or the body’s ability of arteries to expand and at the same time remain flexible. Eating vegetables or fruits containing high amounts of potassium, such as passion fruits, helps keep the blood pressure down, reducing the risk of kidney damage and stroke.[i]

Aids Weight Loss

Most plant-based diets have been associated with better weight loss results than the conventional modes of eating. Also, studies show that low-fat vegan diets are much more effective in aiding weight loss than eating foods with a high amount of fats.

The observation is most likely because of the high fiber content of the plant-based diet. The ability of fiber to boost satiety is a great benefit. Passion fruits are high in fiber and very low in fat and perfectly fit into a good eating plan geared to weight loss.[ii]

Prevents Iron-Deficiency Anemia

Iron-deficiency anemia produces different symptoms, including fatigue, weakness, poor immunity, or impaired cognitive function. Many people who eat a plant-based diet, such as vegans and vegetarians, sometimes find it difficult to maintain sufficient iron stores because plant sources are not easily absorbed.

Fortunately, plant foods contain high amounts of vitamin C, which largely improves iron bioavailability. One cup of passion fruit offers between 21% and 48% of the recommended iron intake. This extraordinary combination is great for reaching the expected blood levels.[iii]

Reduce Inflammation

As mentioned earlier, passion fruit contains high amounts of antioxidants with significant anti-inflammatory effects if taken as supplements. The potent anti-inflammatory effects can be very beneficial to people with osteoarthritis and asthma.

Improves The Immune System

The passion fruit contains vitamin C, a good antioxidant that helps protect the body from the damage that results from free radicals. Also, vitamin C improves the immune system by allowing the human body to absorb additional iron from plant-based foods and might enhance the body’s ability to fight off infections.

Supports Heart Health

The passion fruit contains potassium and is very low in sodium. If eaten with the seeds, the passion fruit contains fiber that can help remove excel cholesterol from blood vessels. High fiber foods can significantly reduce the risks of cardiovascular disease. Eating passion fruit might help control blood pressure. Diets that are rich in potassium and low in sodium help reduce blood pressure.

The fruit is oval or round, either dark purple or yellow at maturity, with a firm to a soft, juicy interior that’s filled with lots of seeds. The fruit can be eaten or juiced.

How To Prepare

To eat, cut the passion fruit in half and use a spoon to scoop out the seeds and pulp. You can use a blender to make juice.

Pressing the passion fruit seeds via a sieve or cheesecloth turns the passion fruit juice into syrup.

You can add the fruit to vegetable or fruit salads, grain bowls, and yogurt dishes. The seeds of a passion fruit make a fascinating decorative addition to non-alcoholic beverages, frozen treats, and cocktails. In Australia, the passion fruit is topped with sugar and cream, while in Mexico, the whole fruit is prepared with chili pepper and lime.
