Pineapple health benefits

Pineapple for digestion

Similar to numerous other fruits and vegetables, pineapple contains dietary fibre, which is an essential part of the healthy functioning digestive system.

Dietary fibre is extremely useful in keeping bowel movements regular and avoiding constipation. Also, they have an important role in maintaining the normal microflora of the intestines, which play a crucial role in the proper digestion of food.

In contrast to many other fruits and vegetables, pineapple contains a significant amount of bromelain which is an enzyme that breaks down protein and improves intestinal function. This property of pineapple leads one to believe that it is possibly a better alternative for the gastrointestinal health.

Pineapple for common cold and sinusitis

Pineapple has long since been used as a traditional remedy for cough and cold. They have lots of Vitamin C which has been reported to be useful in the treatment of common cold.

Additionally, research suggests that bromelain present in pineapple is an excellent anti-inflammatory agent. This means that it can help in the reduction of mucus accumulation in the nose and throat. In a recent clinical trial, 40 chronic sinusitis patients were given a 500mg bromalin supplement twice a day for a period of 30 days. It was found that bromalin can easily pass from the bloodstream into the nasal mucosa. It has been speculated that the ease of diffusion makes bromalin the perfect health supplement for relieving sinusitis inflammation. So, if one catches a cold, then it could be worth trying some pineapple chunks.

Pineapple for diarrhoea

Evidence has suggested that bromelain present in pineapple counteracts some of the effects of certain intestinal pathogens such as Vibrio cholerae and Escherichia coli. The enterotoxin of these pathogens causes diarrhoea. Bromelain is believed to exhibit this effect by interacting with intestinal secretory pathways.

However, an alternate antibacterial mechanism has also been found. Antiadhesion effects are exhibited by active supplementation with bromelain in infection caused by E. coli. This means that bromalin prevents the bacteria from attaching to specific glycoprotein receptors located on the intestinal mucosa (inner lining). Hence, pineapple bromalin may be clinically useful as an antidiarrheal drug.

Pineapple benefits for skin

A healthy and glowing skin is all one needs to create an impact at first sight and pineapple is just the right fruit to help you gain that.

Pineapple for arthritis

Arthritis is a disease which makes the bones fragile and prone to fractures. In Western countries, osteoarthritis is the most common form of arthritis. Pineapple is considered to be a natural anti-inflammatory fruit. Bromelain, an enzyme found in pineapples, is believed to play an important role in the pathogenesis of arthritis. A clinical study conducted on 103 patients suffering from osteoarthritis of the knee suggested that bromelain contains can help reduce inflammation and pain similar to some nonsteroidal anti-inflammatory drugs.

Pineapple for heart health

Modern day lifestyle and dietary choices have significantly increased the risk of various cardiovascular disorders. Cardiovascular diseases or CVDs include a wide range of disorders of the heart and blood vessels, coronary heart disease, stroke, high blood pressure or hypertension, rheumatic heart disease, peripheral artery disease, heart failure, and congenital heart disease.

Studies suggest that bromelain, present in pineapple can reduce the risk of these cardiovascular diseases. Pineapples are effective inhibits blood platelet aggregation, thus minimizing the risk of arterial thrombosis (platelet aggregation in arteries) and stroke. It prevents and minimises the severity of angina pectoris chest pain due to CVD) and transient ischemic attack (caused due to blockage of blood flow to a particular body part).

Additionally, the antioxidants present in pineapple may be helpful in reducing lipid oxidation and formation of plaques in the arteries which is usually responsible for atherosclerosis and high blood pressure.

Pineapple prevents blood clots

Blood coagulation refers to an undesirable transformation of the liquid state of blood into semi-solid. Bromelain increases the serum fibrinolytic activity by inhibiting the synthesis of fibrin which is a protein involved in blood clotting. This phenomenon slows down blood coagulation. Animal-based studies suggest that pineapple exhibits dose-dependent inhibition of blood clotting.

This definitely makes pineapple a very good snack for those who are prone to blood clots and frequent air commuters.

Pineapple for burns

Debridement is the process of removal of the unhealthy tissue which is damaged from wounds or burns. This is essential to promote the healing mechanism. Bromelain present in pineapples contains vitamin C which promotes wound healing . Studies suggest that bromalin when applied topically as a cream with a lipid base, could be useful in accelerating the healing process, and also for the debridement of necrotic tissue (dead tissue).

Pineapple for surgery recovery

The average number of days which might be required for the complete disappearance of the inflammation and pain caused after a surgery is said to reduce if the bromelain is administered before the surgery. Studies and trials indicate that bromelain might be quite effective in the reduction of pain, swelling and bruising in women who are suffering from an episiotomy (a surgical cut made in the vagina to ease childbirth). Bromelain is nowadays also used for treating acute cases of inflammation like sports injuries.

Pineapple for cancer

Cancer is one of the most severe chronic diseases of the present time. A lot of research has been going on to find anti-cancerous properties in natural food items to battle this fatal disease. Studies suggest that bromelain present in pineapple has potent anticancer activities. It has been found that bromalin has an inhibitory impact on cancer cell growth and their respective microenvironment.

Also, the modulation of inflammatory, immune and haemostatic systems is of significance in reducing cancer growth.

Bromelain is also said to decrease the activity of the cell survival regulators such as Erk and Akt. This, in turn, helps the promotion of apoptotic cell death in tumours. Studies showed that administration of Bromelain resulted in tumour regression after 24 hours of inoculation.
