So, what is pineapple good for? Over the years, science has heavily researched on pineapples and the health benefits they offer. The following section talks about them in detail.

What Are The Health Benefits Of Pineapples?

Pineapple contains bromelain, a digestive enzyme that offers most of its benefits. Bromelain has been found to combat cancer and fight inflammation and associated ailments. The fruit also boosts your immunity and strengthens bones. Let us check out the other benefits of eating pineapple.

1. May Aid Weight Loss

Studies show the possible anti-obesity effects of pineapples. Rats fed on a high-fat diet showed a reduction in body weight, body mass index, body fat accumulation, and liver fat accumulation after the intake of pineapple juice (2).

Pineapple juice was observed to decrease lipogenesis (formation of fat) and increase lipolysis (the breakdown of fats to release fatty acids) (2).

Pineapple may appear to be the ideal food to burn belly fat, although we need more research in this regard.

2. May Aid Digestion

The most important component of pineapple is bromelain, a potent digestive enzyme. Studies show that bromelain (Digestive enzyme) supplementation may help in the breakdown of proteins (3).

It can help treat pancreatic insufficiency, a digestive disorder in which the pancreas doesn’t produce enough of certain enzymes the body uses to digest food in the small intestine (3).

A formula with bromelain as one of the primary ingredients could relieve excess flatulence and diarrhea (3).

A fruit enthusiast blogger explored the role of pineapples in weight loss, emphasizing their nutritional richness. They mention, “When I started inviting pineapple to my daily food fiesta, I noticed my tummy didn’t feel like a bloated balloon at a kid’s party anymore. It was more like a beach ball, light and more manageable (i).” Advising on incorporating pineapples in balanced meals, the blogger cautions against relying on pineapple detox diets, promoting sustainable harmony in dietary choices for effective weight management.

3. May Help Reduce Cancer Risk

Studies have stated that bromelain in pineapples may have anti-cancer properties, thereby promoting cancer prevention. The enzyme may have a direct impact on cancer cells and their environment (4).

Bromelain exhibits anti-cancer effects on colon cancer cells. Foods containing bromelain are considered good candidates for reducing the risk of colorectal cancer (5).

Bromelain can also hinder cancer progression by fighting inflammation, a primary contributor to cancer. It prevents the further generation of cancer cells by exposing them to the immune system. Various traditional and clinical reports indicate the anti-cancer properties of pineapple’s bromelain. Further studies may offer more promising results in this area (6).

In mouse studies, bromelain was also found to inhibit the growth and spread of breast cancer cells. It also could reduce the survival of these cells (7).

4. May Help Combat Inflammation

In animal studies, bromelain has been reported to have therapeutic effects on various inflammatory diseases, including inflammatory bowel syndromei  A spectrum of illnesses that lead to gastrointestinal pain and swelling caused due to chronic inflammation. . Bromelain exposure could remove a number of cell surface molecules that contribute to inflammation (8).

Bromelain in pineapples also achieves this by reducing the production of pro-inflammatory cytokines and chemokines (9). These are compounds in the human system that promote inflammation, more so in the case of inflammatory bowel disease.

Pineapple extract was also found to treat other issues related to inflammation, including allergic airway disease. The fruit’s enzyme could alter the activation and expansion of specific cells of the immune system. The study was conducted on mouse cells (10).

5. May Help Treat Arthritis And Promote Bone Health

Bromelain may also aid in the treatment of osteoarthritisi  A form of arthritis that develops as the pliable tissue at the ends of bones ages and wears down. . The enzyme exhibits analgesic properties, especially in inflammatory pain in humans. It achieves this by directly influencing bradykinin, a pain mediator that causes the contraction of smooth muscle and dilation of blood vessels (11).

Pineapples also contain manganese, a mineral important in bone formation. They also contain vitamin C that supports the formation of collagen in bones. Pineapples can promote the growth of bones in the young and strengthen bones in older people (12).

The anti-inflammatory properties of pineapple’s bromelain may also help treat rheumatoid arthritisi  A condition that causes persistent inflammation and affects several joints, especially those of the hands and feet. pain (13).

6. May Improve Cardiac Health

Bromelain in pineapples was found to reduce the aggregation of blood platelets. This may help treat acute thrombophlebitis (a condition characterized by blood clots). However, more studies on human populations are needed to conclude the beneficial effects of bromelain on cardiovascular disease (14).

Bromelain may also break down cholesterol plaques, further promoting heart health (15). Its efficacy in the treatment of other cardiac diseases, including coronary heart disease, rheumatic heart diseasei  A disorder when rheumatic fever (a condition brought on by untreated strep throat) irreparably damages the heart valves. , congenital heart diseasei  A collective term for a group of birth defects that impair the heart's ability to beat normally, potentially affecting blood flow. , and heart attack is yet to be proven.

7. May Promote Immunity

Bromelain in pineapples can modulate the immune system and potentially accelerate wound healing (16).

Children consuming pineapple juice also had a lower risk of contracting microbial infections. The fruit was found to increase the concentrations of the disease-fighting white blood cells by four times (1).

In another study, children with sinusitis showed faster recovery with a bromelain supplement (17).

Another study sheds light on bromelain’s potential to treat asthma symptoms. It may exert a therapeutic effect on various allergic airway diseases, including allergic asthma (18).

8. May Enhance Recovery

The anti-inflammatory properties of pineapple’s bromelain can aid recovery. This is especially true in case of a much-needed recovery after surgery. More studies are needed to establish bromelain’s effectiveness in post-surgery recovery (19).

In a study, bromelain intake significantly reduced pain in patients undergoing dental surgery. The enzyme offered similar relief as other anti-inflammatory drugs (20).

Bromelain was also found to reduce feelings of fatigue. It reduced muscle damage and improved recovery across consecutive days of cycling (21).

9. May Improve Skin Health

There is limited research in this aspect. The vitamin C in pineapples may benefit the skin. The vitamin promotes collagen production and may protect the skin from damage (1).

Pineapples are amazing-looking fruits with equally amazing benefits. There is no reason you shouldn’t add them to your diet. But how do you do it?

How To Add Pineapples To Your Diet

Pineapples are affordable and easy to eat. In addition to their goodness, they taste delicious too. You can enjoy pineapples in the following ways:
