6 Healthy Properties of Kiwi:
1. It Facilitates the Digestion of Foods Rich in Protein:
Thanks to its actinidine content, regular consumption of kiwifruit can promote protein digestion.
“In fact, kiwi juice can be used to break down meat proteins and thus make it soften”.
Several studies carried out in animals have confirmed that the actinidin present in kiwifruit improves the breakdown and digestion of protein-rich foods, which can prevent intestinal problems related to digestion. If you have difficulties in consuming protein and experience a feeling of excessive filling after eating it, eating kiwifruit can help reduce this uncomfortable sensation.

Constipation is a condition characterized by the difficulty of defecating due to an alteration in bowel movements that causes hard stool formation. In the long term, constipation can become a more or less serious disorder that can cause severe pain when going to the bathroom and even cause an anal fissure. The abundant consumption of water is one of the most known and widespread methods that are used both to prevent and to combat constipation and, in this aspect, kiwi can help you.

- Increases softness and ease of bowel movements.
Its high amount of fiber, mainly insoluble, is responsible for these effects and it has been shown that eating 2 kiwis daily for two weeks considerably relieves constipation symptoms in patients with chronic constipation. Finally, there are also indications that the intake of 2 kiwis per day increases the frequency of bowel movements in people with irritable bowel syndrome.

Today, heart disease is the order of the day and very few people know that it can be avoided with just a few small changes in diet. There are many nutrients that have been proven to reduce the risk of heart disease and one of them is vitamin C: a kiwi gives you more than 100% of the RDA. In fact, it has been observed that having reduced levels of vitamin C in the body increases the risk of heart attack 2.4 times, this risk being even higher if you suffer from hypertension or obesity.

Vitamin C significantly reduces oxidative stress caused by free radicals, which causes serious damage to proteins, cells and molecules such as DNA, which increases the risk of developing cancer.
