Cactus fruit are a bit hard to harvest because of the prickled exteriors known as glochids. These glochids can be really painful when they stick to hands.  But did you know that behind all those spines are compounds and nutrients beneficial to our bodies? Let’s explore what cactus fruits are good for.

Nutrients rich

The different varieties of cactus have different nutritional profiles. What they have in common are fiber, vitamins, and minerals. They are also rich in antioxidants like phenolic acid and flavonoids that protect our bodies from oxidative stress caused by free radicals that cause diseases.

Weight loss

Overweight persons are at risk of cancer, mental illnesses, and osteoarthritis. The fiber in cactus fruits helps in fat excretion and reduce the absorption of energy. The 3g fiber content in cactus fruit also reduces frequent hunger pangs, making you feel fuller for longer.

Skin and hair health

The polyunsaturated fats in cactus fruits play a good role in maintaining glowing skin and shiny hair. Vitamin K and E play the role of rejuvenating the skin and preventing wrinkles from forming. Eating cactus is actually one of the ways you can delay the aging of your skin.

Oil from cactus fruit helps nourish the scalp upon being applied to the hair. When mixed with some cucumber, coconut oil, and coconut milk, you will have a hair conditioner to protect your hair from getting dry in the summer heat.

Maintaining healthy liver

The liver is one crucial organ in the human body. It helps detoxify chemicals and metabolize drugs. Our lifestyle choices might damage the liver, but the cactus fruit has been found to have antioxidants that help in preventing inflammations that damage the liver. In fact, this fruit has been used in liver treatment from back in the olden days. 

Maintaining blood sugars

Cactus fruits have been found to help reduce blood sugars and insulin levels in healthy persons and those with type 2 diabetes. This is all thanks to the fiber and the pectin present in the fruit.

Boosting immune system

The fruit of the cactus has vitamin C that helps in the growth of our bodies and the production of white blood cells. That way, the body toughens and fights any disease-causing organisms that might attack our bodies. Vitamin C also fastens wound healing, repairs the damaged body tissues, absorbs iron, and maintains the health of our bones and teeth.

Dragon fruits might closely be related to cactus fruit, but they differ in so many ways. Understanding their differences will clear any confusion on these two incredible fruits. So check out these differences in terms of:


Dragon fruits skin is famous for its scale-filled skin that also gave birth to their names. On the other hand, the cactus fruit is covered by spines that can hurt your hands if extra care is not observed.

Can you eat cactus fruit?

Some people believe that cactus fruits aren’t safe for consumption. I pity them, for they are really missing out on something so nutritious. So to clear those doubts, I want to answer whether or not you can eat the cactus fruit.

Well, cactus fruits are very edible and safe for consumption. Once you get those spiky messes from the fruit, you will just skin the fruit and enjoy its juices that have this bubblegum taste.

Apart from the taste, this fruit is packed with essential minerals, vitamins, and fiber necessary for maintaining a healthy immune system. Minerals like potassium, magnesium, and calcium are present in the fruit.

So if you are one of those who believe that cactus fruits are poisonous, then it’s time to change that mindset. Either way, there are different varieties of cactus fruits, and not all of them are edible. But with the prickly pears, it’s a different story.

 How to eat cactus fruits

The Cactus fruit plant has three edible parts: the cactus pad, the flower petals, and the fruits. Here, we will cover how to eat the cactus fruit.

Getting the cactus

You can either buy or harvest your cactus fruit. If you are harvesting it yourself, do not forget to have gloves on and have a pair of tongs to twist the fruit from the stem. A mistake of harvesting them without gloves might lead to the fruits’ thorns getting into your skin.

Going for store-bought cactus fruits doesn’t guarantee on their ripeness and good taste. So to increase the chance of purchasing a good fruit, go for that with a bright purple color. That color is an indication that the fruit is ripe.

If you harvest your fruits directly from the plant, do not forget to remove the spines before going to the next step.


To skin your fruit, use a fork to keep it steady and remove the thick skin from the fruit with a knife. Discard the skin upon removal and be keen so you do not slice off the seeds.

Removing seeds

As mentioned earlier, cactus fruit seeds are a little hard, and might make you not enjoy it as you would if it didn’t have those hard seeds. This step is necessary, especially if there will be a kid enjoying the fruit with you.

To remove them, you can run the fruit through a food mill and end up with some delicious juice. If you do not mind eating the fruit with seeds, then you can directly go into slicing it then serving them on skewers. That would call for spitting the seeds after every bite you take.

How to eat a cactus pear

Cactus pear is also the cactus fruit. So the eating process is quite the same as the above. If you will be harvesting the fruit, you can burn the glochids on a flame. As they burn, there will be little pop sounds and sparks being produced. So the next step will be skinning and digging straight to enjoying the fruit.

The cactus pear has been widely used in making candies and jams and can also be incorporated into salads. You can also make some juice that can be used in flavoring cream cheese or mix it with some orange and lemon juice to make some salad sauce.

What does cactus fruit taste like?

Cactus fruits’ taste can differ from person to person. The fruit has a pineapple taste that closely resembles that of a raspberry or a strawberry. Its sweet pulp might also give the hint of some natural bubblegum and watermelon taste. The difference in taste is brought about by the age of the fruit. The first fruits tend to have a more robust flavor which keeps getting stronger as the fruit grows.
