Pineapple Health Benefits & Nutrition

Bromelain — Pineapple's Unique Enzyme

Pineapple is the only significant dietary source of bromelain — a mixture of proteolytic (protein-digesting) enzymes found throughout the plant but concentrated in the core and stem. Bromelain has been clinically studied for reducing post-surgical swelling and bruising, improving symptoms of sinusitis, and reducing knee pain in osteoarthritis. It is approved as a medicine in Germany for post-traumatic swelling. Bromelain also makes pineapple an effective meat tenderiser — the same enzymes that digest dietary protein break down tough muscle fibres in meat.

Vitamin C — 53% of Daily Value per Cup

A cup of pineapple chunks provides 79mg of vitamin C — 88% of the adult daily requirement. Per 100g, pineapple contains 47.8mg, making it one of the better tropical fruit sources of this essential vitamin. Vitamin C in pineapple is notably stable compared to other fruits because pineapple's natural acidity (pH ~3.5) protects ascorbic acid from oxidation.

Manganese and Bone Health

A cup of pineapple provides 1.5mg of manganese — 65% of the daily value for men and 84% for women. Manganese is essential for bone formation, as it is required for the synthesis of bone matrix proteins. It also activates superoxide dismutase (MnSOD) — the mitochondrial antioxidant enzyme critical for cellular energy production. Pineapple is one of the most concentrated dietary sources of manganese available.

Anti-Inflammatory Effects

Beyond bromelain, pineapple contains quercetin, ferulic acid, and other polyphenols with anti-inflammatory properties. A 2016 study found that pineapple consumption significantly reduced markers of inflammation in children with digestive tract inflammation. The combination of bromelain's direct enzyme action and polyphenol antioxidant effects makes pineapple particularly effective at modulating the inflammatory response.

Frequently Asked Questions

How many calories in pineapple?
Pineapple contains 50 calories per 100g. A cup of pineapple chunks (165g) has 83 calories. A standard slice (84g) has about 42 calories. Use the slider above to calculate for any weight.
What is bromelain in pineapple?
Bromelain is a mixture of proteolytic (protein-digesting) enzymes unique to pineapple. It is found throughout the plant but concentrated in the core and stem. Clinically, bromelain is used to reduce post-surgical swelling, improve sinusitis symptoms, and reduce joint pain. It also makes pineapple an effective natural meat tenderiser.
Is pineapple good for digestion?
Yes. Bromelain helps digest proteins and may reduce bloating and digestive discomfort. Pineapple's fiber (1.4g/100g) supports healthy bowel function. Some people find pineapple particularly helpful when eaten with protein-heavy meals as the bromelain assists protein breakdown.
Is pineapple keto?
No. Pineapple has 11.7g of net carbs per 100g and a moderate glycemic index of ~59. It is not suitable for ketogenic diets.
Is pineapple good for weight loss?
Yes, in moderate portions. At 50 kcal per 100g with 86% water content, pineapple is relatively low in calories. Its natural sweetness and bromelain content make it a good fruit choice for calorie-controlled diets.
Can you eat pineapple core?
Yes — the core is edible and actually contains higher concentrations of bromelain than the flesh. It is tougher and less sweet, but fully safe to eat. Many people blend it into smoothies or juice it to benefit from the additional bromelain and fiber content.
