Pineapple — 50 kcal

Pineapple brings an enzyme to the table that no other common fruit can match. At 50 kcal per 100 g, it delivers 13.1 g of carbohydrates with 9.9 g of sugar and 1.4 g of fiber, wrapped in 86 g of water. With 0.5 g of protein and a negligible 0.1 g of fat, pineapple is lean, tropical fuel. But the real headline is bromelain — a proteolytic enzyme concentrated in the core that actively breaks down protein, which is why your tongue tingles after eating fresh pineapple and why it makes an outstanding meat tenderizer.

What's Inside

Vitamin C dominates at 47.8 mg per 100 g (about 53 % DV), making pineapple one of the top fruit sources for immune support and collagen synthesis. Manganese is the sleeper star at 0.927 mg (roughly 40 % DV) — essential for bone formation, blood clotting, and activating the antioxidant enzyme superoxide dismutase. Vitamin B6 (0.112 mg) supports neurotransmitter production and amino acid metabolism. Thiamin (0.079 mg) helps convert carbohydrates into usable energy. Folate (18 mcg) contributes to cell division, potassium (109 mg) supports heart rhythm, and copper (0.11 mg) aids iron absorption and red blood cell formation. Bromelain, beyond its digestive benefits, has been studied for anti-inflammatory effects comparable to some NSAIDs, particularly for post-surgical swelling and joint health.

Getting It Right

Twist a leaf from the crown — if it releases easily, the pineapple is ripe. The bottom should smell sweet and fragrant, not fermented. Cut by slicing off the top and bottom, standing the fruit upright, and carving off the skin in vertical strips following the curve. Do not discard the core: it is tougher but contains the highest concentration of bromelain. Dice it finely and add to smoothies or stir-fries. Grill pineapple rings at high heat for 3 minutes per side until char marks appear — the Maillard reaction intensifies sweetness dramatically. Pair with chili flakes, lime, and coconut for a Thai-inspired combination. Never add raw pineapple to gelatin desserts — bromelain prevents setting. Cooking above 70 °C deactivates the enzyme if you need gelatin to set.
