How Pineapple's Bromelain Enzymes Provide Health Benefits

The Unique Enzyme Bromelain in Pineapples

Pineapples contain a unique enzyme called bromelain that breaks down proteins. This enzyme is found in highest concentrations in the pineapple stem, but is also present throughout the juicy fruit flesh.

When you eat fresh pineapple, the bromelain enzymes start breaking down proteins in your mouth and digestive tract. This is where the idea comes from that pineapple is “eating you back” as you eat it due to its enzymatic effects.

Oral Effects of Bromelain

The proteolytic enzymes in pineapple can help break down the biofilm on teeth, removing built-up plaque and bacteria. Bromelain creates an unfriendly environment for microbes in the mouth and on the tongue.

Some natural oral health products include pineapple extracts for this reason. However, bromelain is not a substitute for regular oral hygiene.

Digestive Effects of Bromelain

Pineapple’s bromelain enzymes help digest protein in the stomach by breaking down amino acids. This can improve the digestion and absorption of proteins from meat, dairy, legumes, and other foods.

The enzymes may also help reduce excessive mucus in the digestive tract, improving gut motility and alleviating constipation for some people.

The Benefits of Pineapple Bromelain

The unique health benefits of pineapple are directly linked to its bromelain content. Eating fresh pineapple regularly can provide the following benefits:

Supports Immune Function

Bromelain demonstrates natural anti-inflammatory and anti-edema effects. It supports cytokine production which helps modulate the immune system response.

Some research indicates bromelain can enhance immune function and speed recovery from illnesses. More studies are still needed, but the evidence is promising.

Reduces Inflammation

The enzymes in pineapple decrease prostaglandin levels which are compounds involved in inflammation. Bromelain also decreases neutrophil migration and T-cell activation both linked to inflammatory responses.

Supplementing with bromelain is shown to reduce inflammation and swelling following injuries or surgery. It may also help relieve arthritis symptoms.

May Have Anti-Cancer Activity

Early research suggests bromelain may have cancer-fighting abilities. Test tube studies show it promotes cell death in certain cancer cells and prevents tumor growth.

Bromelain also shows effects modulating key pathways and proteins associated with cancer progression. More human clinical research is still needed to confirm therapeutic efficacy.

Improves Circulation

The anti-inflammatory and anticoagulant properties of bromelain can promote healthy blood flow and prevent circulatory issues. Bromelain helps maintain tissue permeability and prevents platelet aggregation.

This natural support for circulation may help reduce risk of cardiovascular disease, varicose veins, and other related conditions.

Aids Skin Health

When applied topically, bromelain can remove dead skin cells and promote new skin growth and rejuvenation. It may help reduce the appearance of sun damage, age spots, fine lines, and wrinkles.

Some cosmetic products include bromelain from pineapple extract for its skin-enhancing effects when applied to the face and body.

Speeds Up Recovery

The ability of bromelain to reduce inflammation and swelling makes it effective for hastening recovery. Supplementing with bromelain is commonly used to speed recovery following injuries, surgery, or exercise.

It helps the body undergo repair processes faster to accelerate return to normal function. Bromelain increases blood flow to injured tissues which also promotes healing.

May Aid Weight Loss

Proteolytic enzymes like bromelain may help break down and digest fat cells, particularly when protein intake is already low as in a ketogenic or paleo diet. This enhanced fat breakdown may support weight loss.

However, more studies specifically analyzing bromelain for weight loss effects are still needed. Any impacts are likely mild without further calorie restriction and exercise.

Safety and Side Effects

For most people, eating pineapple and benefiting from its bromelain is completely safe. However, there are some precautions to keep in mind:

Allergies

Pineapple allergy is not uncommon. Symptoms like itching, swelling, and redness are usually localized to the mouth. However, more systemic reactions are possible in sensitive individuals.

Medication Interactions

Bromelain can interact with some medications like blood thinners, antidepressants, chemotherapy drugs, and antibiotics. Consult a doctor before consuming large amounts of pineapple if you take any medications.

Digestive Issues

The proteolytic effects of bromelain on the digestive system may cause diarrhea, nausea, vomiting, and stomach pain in some cases. Start with small amounts of pineapple.

Menstrual Flow Changes

Pineapple’s effects on prostaglandins may increase menstrual flow for some women. Pineapple should be avoided as a supplement during pregnancy due to risks of the uterine stimulant effects.

Tips for Selecting and Eating Pineapple

Follow these tips to pick ripe, fresh pineapple with the highest bromelain content:

Picking a Pineapple

- Choose pineapples that feel heavy for their size with fresh green leaves.

- Avoid soft or mushy pineapples with dark spots.

- Select fruits with a strong sweet pineapple aroma.

Cutting a Pineapple

- Always use a sharp knife and cutting board.

- Slice off the top and bottom to create flat surfaces.

- Stand upright and cut off outer skin from top to bottom.

Eating Pineapple

- Consume soon after cutting for best flavor and bromelain activity.

- Chew thoroughly to activate enzymes before swallowing.

- Drink some water to offset bromelain effects on the mouth.

Maximize the benefits by enjoying fresh pineapple within a day or two of purchasing. Canned pineapple has lower bromelain levels due to processing and pasteurization but still offers some benefits.

Frequently Asked Questions

Does cooking destroy bromelain in pineapple?

Yes, exposure to high temperatures through canning, grilling, baking or other cooking methods destroys much of the bromelain enzyme activity in pineapple. For the highest bromelain intake, consume fresh raw pineapple.

What does bromelain do in the body?

Bromelain provides systemic effects through digestive absorption into the bloodstream. Its key actions include reducing inflammation, stimulating immunity, improving circulation, speeding recovery, and enhancing skin health by breaking down proteins.

Is it bad to eat a lot of pineapple?

Eating large amounts of pineapple can cause digestive upset like diarrhea, nausea, or stomach pain for some people due to the high bromelain content. Moderation is recommended, with adverse effects more likely in amounts over one whole pineapple per day.

Does pineapple tenderize your lips?

The bromelain enzymes in pineapple can help exfoliate and soften skin on the lips, removing dead cells. However, the tingling sensation is usually just the mild irritant effects of bromelain on sensitive lip tissue rather than actual tenderizing.

Is pineapple anti-inflammatory?

Yes, pineapple contains bromelain which provides potent anti-inflammatory effects systemically when absorbed from fresh fruit. The enzymes help regulate prostaglandins and other compounds involved in the inflammatory response.
