Pineapple is a highly nutritious tropical fruit which has become highly popular and is available in various forms: fresh fruit, frozen fruit, juice, tablets and capsules. The top crown of the fruit contains a bud that indicates when the fruit is ready for cutting. The crowns from the top are used for propagation, as pineapples don’t have any viable seeds. The plant of this fruit grows to a height of 1 m. Pineapples grow in areas of relatively low rainfall (50 to 200 cm).
The pineapple is native to South America and was brought to Europe by Spanish explorers. Traditional uses of pineapple include the brewing of pineapple wine, the production of fibre, and medicinal use to induce menstruation, kill parasitic amoebas, and expel worms. Few clinical trials support that bromelain, a crude, aqueous extract of pineapple, was used as an anti-inflammatory agent.

In contrast, others are more tender and are challenging to be shipped over long distances. The varieties of pineapples also differ in sweetness, acidity and fibre content.
There are dozens of different varieties of pineapples, but some are more commonly available as compared to others. The most popularly available variety of pineapple is the smooth cayenne (also known as cayena Lisa in Spanish)
One can divide pineapples into 4 major types :
Smooth Cayenne Pineapples

8 Health Benefits of Pineapple
Pineapple, a tropical fruit known for its sweet and tangy taste, offers a range of potential health benefits that make it a valuable addition to your diet. Let’s explore these benefits.
1. Improves Digestion
Pineapples are rich in dietary fibre, which plays a crucial role in maintaining a healthy digestive system. Fiber aids in regular bowel movements and prevents constipation. Moreover, pineapple contains an enzyme called bromelain, which assists in the breakdown of proteins into amino acids and peptides. What’s remarkable about bromelain is that it operates effectively in both the acidic environment of the stomach and the alkaline environment of the small intestine. This dual functionality ensures efficient digestion, particularly benefiting individuals who experience digestive issues or pancreatic insufficiency.
2. Promotes Injury Healing
Bromelain, found in pineapple, exhibits excellent wound-healing properties. It possesses anti-inflammatory qualities, reducing inflammation, swelling, and bruising following injuries or surgical procedures. This action not only speeds up the healing process but also minimises pain and discomfort.
3. Supports Cardiovascular Health
Pineapple’s bromelain content may have a positive impact on cardiovascular health. It helps prevent and reduce the severity of angina attacks and transient ischemic attacks (TIAs). Additionally, bromelain aids in the breakdown of cholesterol plaques, thereby reducing the risk of atherosclerosis, a condition characterised by the hardening of arteries.
4. Provides Relief in Arthritis Symptoms
Bromelain in pineapple possesses anti-inflammatory properties. Various studies suggest that bromelain, due to its anti-inflammatory properties, could provide relief from the inflammatory pain associated with arthritis. While more research is needed, early findings indicate the potential of bromelain in managing arthritis symptoms.
5. Strengthens Bones and Teeth
Pineapple contains a good amount of calcium and manganese, essential minerals that contribute to strong gums, bones, and teeth. Regular consumption of pineapple can help maintain dental health and bone strength over the long term.
6. Good for Eyes
Pineapple consumption may reduce the risk of macular degeneration, an age-related eye disease. This benefit is due to the presence of vitamin C and antioxidants in pineapple. These nutrients play a role in maintaining good vision and preventing eye-related issues.
7. Skin Benefits
Pineapple’s vitamin C and antioxidant content can rejuvenate the skin and address various skin problems such as acne, rashes, and skin damage. Additionally, these compounds reduce the risk of sun damage, uneven skin tone, inflammation, and scars. Incorporating pineapple into your diet may contribute to healthier, more youthful, and smoother skin. Pineapple can also benefit your hair by providing essential nutrients to the hair and scalp, promoting shinier and healthier locks.
8. Promotes Weight Loss
While not yet conclusive for humans, pineapple, specifically raw pineapple juice, may possess anti-obesity properties. Bromelain in pineapple has been linked to a higher metabolic rate, enabling the body to burn calories more efficiently. Furthermore, bromelain aids in digestion, enhancing nutrient absorption. These combined effects could contribute to weight loss in individuals.
Summary
Incorporating Pineapple into a regular diet can provide multiple health benefits. Pineapple is rich in fibre, which benefits digestion. Pineapple contains an enzyme called bromelain, which breaks down proteins into amino acids and improves digestion. It has excellent wound-healing properties that reduce inflammation and help in faster recovery from injuries. Bromelain also reduces the risk of cardiovascular attacks. The anti-inflammatory property of this fruit helps relieve arthritis pain, while the Vitamin C and antioxidants improve vision, bone and teeth strength and improve skin and hair texture.

4. Squeeze the juice of one lemon over the salad to enhance the flavours and give it a tangy twist.
5. Add a pinch of salt to taste and gently toss all the ingredients together until they are well combined.
6. Refrigerate the salad for about 30 minutes before serving to allow the flavours to set and the salad to chill.
Recommended Intake and Precautions
The dietary guidelines suggest 21 to 25 g of pineapple for women and between 30 to 38 g per day for men. One must not consume pineapple on an empty stomach to avoid acidity. The best time advised for its intake is said to be around 10-11 a.m. as a mid-morning snack or about 4-5 p.m. as an evening snack.
Two slices of pineapple contain approximately 100 mg of ascorbic acid (vitamin C). The usual dosage of bromelain is 40 mg, taken 3 to 4 times a day. Pineapple products such as liquid, tablets and capsules contain 500 mg of bromelain and a dosage of 500-1000 mg daily.
Potential Side Effects
The pineapple is rich in high glucose and sucrose content. Some people may have a blood sugar spike when consumed in excess. Blood sugar levels get elevated by the carbs included in most fruits. The carbohydrate content in a half cup of pineapple is 15 grams.
The juice and stem of pineapples contain the enzyme bromelain. While natural bromelain does not appear to be dangerous, it may make bleeding more likely if taken along with blood thinners.
The gums and dental enamel may deteriorate as a result of the pineapple’s acidity. Moreover, it may result in oral cavities and gingivitis. This event happens as a result of our immune system mistaking the protein in pineapple for pollen or another allergy.
Those who use pineapple juice should exercise caution. It could cause a stomach ailment. Therefore, one should not consume it on an empty stomach.
Summary
Along with all the nutritional benefits that pineapple provides, there are also a significant amount of possible side effects that one needs to take into consideration before taking excessive dosage of the fruit. The high glucose and Sucrose content can lead to high blood sugar levels. The enzyme bromelain might also behave differently with the body. It can cause bleeding more likely if taken with blood thinners. Pineapple’s acidity might affect gums and dental enamel. While drinking pineapple juice on an empty stomach can cause acidity and an uncomfortable stomach. Hence, a careful and considerate intake of pineapple is good for healthy eating.
HealthifyMe Suggestion
You can use pineapple as a way to curb your sweet cravings. Slice your pineapple and then place the slices on a hot pan and sprinkle a little jaggery powder on top. Flip the slices and sprinkle jaggery on the other side. Let the pineapple slices caramelise in the pan and then serve hot as a nutritious dessert.
