PINEAPPLE (Ananas comosus) has been described as one of the most important commercial fruit crops in the world. The fruit is either consumed or served fresh, cooked or juiced but the most effective way to harness the nutritional and medicinal benefits of pineapple is to juice it.

The International Journal of Nutrition and Food Sciences 2015, vol 4, reveals that pineapple juice contains balanced sugar of 14 per cent, with a whole lot of vitamin C and citric and malic acids which help prevent the occurrence of certain diseases like cancer. It has also been proven to cure different disease conditions like diabetes, asthma, obesity, other problems of the heart and digestion.

Pineapples have been proven to help lower blood sugar in diabetic patients, since it is a fat-free fruit that is rich in fibre and vitamins.  The study showed that pineapple  has a higher effect on blood sugar level than most other fruits if consumed in equal quantities. It was discovered that one cup serving of fresh pineapple juice contains 1.40 grammes of fibre.

However, according to an analysis from the Institute of Obesity, Nutrition, and Exercise at the University of Sydney, Australia, fresh whole pineapple has a higher Glycaemic Index (GI) ranking of about 59 when compared to other fruits. But while the higher GI ranking might make pineapple fruit unsuitable for a diabetic patient, experts say there are ways to eat them safely. It was said that a portion of pineapples could be sticked to and paired with a protein diet in order to slow the rise in blood sugar.

In the International Journal of Nutrition and Food Sciences, the benefits of pineapple leaves in the treatment of diabetes was analysed. It was discovered that the leaves have anti-hyperglycemic and analgesic properties that can be used as a cheaper and alternative source of medicine for reducing high blood sugar level of diabetic patients.

According to the study, fresh pineapples are rich in bromelain and bromelain has significant anti-inflammatory effects such as reducing swelling in inflammatory conditions like acute sinusitis, sore throat and arthritis.

Pineapple enzymes were used successfully to treat rheumatoid arthritis and tissue repair, which could be as a result of injuries and diabetic ulcers.

Pineapple was said in the study to cure colds, mouth, throat and bronchial infections. It likewise showed that the enzyme bromelain in pineapple acts as a natural stain remover, which helps break up plaques, thereby preventing gum diseases and ensuring that the teeth are healthy.

One of the best properties of pineapple is its diuretic function. It was observed that pineapple helps to eliminate toxins through the urine and is said to be beneficial for patients with kidney, bladder and prostate ailments.

The Journal of Nutrition and Food Sciences reports that one cup of pineapple juice provides 73 per cent of the daily recommended amount of manganese and this means that the high content of manganese can help to boost fertility by enhancing the quality of sperm produced.

The study pointed to the effectiveness of using pineapple juice to treat problems of infertility. It noted that pineapple juice’s high content in manganese can also help build stronger and healthy bones and connective tissues, especially in aged people. A 1994 study suggested that manganese, along with other trace minerals, may be helpful in preventing osteoporosis in post-menopausal woman.
