Protein in Pineapple
One 1 cup pineapple chunks of pineapple contains 0.9g of protein at 83 kcal. That\'s a protein-per-calorie ratio of 1.1g per 100 kcal — effectively no protein contribution — count this as a carb or fat source instead.
Protein by portion size
| Portion | Protein (g) | Calories | g protein / 100 kcal |
|---|---|---|---|
| 1 cup pineapple chunks (~165g) | 0.9 | 83 | 1.1 |
| 1 slice pineapple (~84g) | 0.5 | 42 | 1.2 |
| 100g pineapple | 0.5 | 50 | 1.0 |
| 1/2 medium pineapple (~454g) | 2.5 | 227 | 1.1 |
| 1 cup pineapple juice | 0.9 | 132 | 0.7 |
How much pineapple to hit your protein target?
Phillips & Van Loon 2009 (JISSN) established 0.4 g/kg per meal as the per-meal threshold to fully stimulate muscle protein synthesis — roughly 25–40g for most adults. To hit those targets purely from pineapple:
- 4583g of pineapple for 25g protein (~2305 kcal)
- 7333g of pineapple for 40g protein (~3689 kcal)
- Per 1g of protein from pineapple: 92.2 kcal
What this protein density means
For perspective, the highest-density protein whole foods cluster around 15–19g of protein per 100 kcal: chicken breast 18.8, white fish 16–17, Greek yoghurt 17 (non-fat), tuna 15. Medium-density sources (5–12 g/100kcal) include eggs, beef, salmon, tofu, and lentils. Below 4g/100kcal, foods are primarily carb or fat sources with incidental protein. Pineapple at 1.1g/100kcal is not a primary protein source. Pair it with chicken, fish, eggs, Greek yoghurt, or legumes to bring meal-level protein up to the 25–40g per-meal MPS threshold.
Protein density comparison
Reference points for context (g protein per 100 kcal):
- Chicken breast (cooked, skinless) — 18.8g/100kcal
- White fish (cod, tilapia, cooked) — 16–17g/100kcal
- Greek yoghurt (plain, non-fat) — 17g/100kcal
- Tuna (canned, drained) — 16g/100kcal
- Cottage cheese (low-fat) — 14g/100kcal
- Eggs (whole) — 8g/100kcal
- Lentils (cooked) — 8g/100kcal
- Whole milk (full fat) — 5g/100kcal
- Rice (cooked white) — 2g/100kcal
- Avocado — 1.2g/100kcal

Frequently asked questions
- How much protein is in pineapple?
- Pineapple contains approximately 0.9g of protein per 1 cup pineapple chunks (83 kcal). Per 100g, that's 0.5g of protein. The protein-per-calorie density is 1.1g per 100 kcal — classified as minimal.
- Is pineapple a good source of protein?
- Pineapple is not a meaningful protein source — treat it as a carb or fat food in your daily macros. For protein targets, focus on chicken breast, fish, eggs, Greek yoghurt, legumes, or tofu. For comparison: chicken breast delivers 18.8g protein per 100 kcal; Greek yoghurt 17g; eggs 8g; lentils 8g; rice 2g.
- How much protein do I actually need per day?
- The Morton 2018 meta-analysis in the British Journal of Sports Medicine (49 randomised trials, 1,863 subjects) established 1.62 g/kg of body weight per day as the dose-response plateau for muscle gain from resistance training. For active adults during fat loss, the Helms 2014 review recommended 1.8–2.2 g/kg of total body weight to preserve lean mass. The old RDA of 0.8 g/kg is a population minimum, not an optimum. For a 70 kg adult, evidence-based daily protein targets are 112–154g.
- How is protein quality measured beyond grams?
- The Digestible Indispensable Amino Acid Score (DIAAS) is the modern protein quality measure, evaluating both amino acid profile and digestibility against human requirements. Animal proteins — whey, casein, eggs, chicken, fish — score 1.0+ (complete and highly digestible). Most plant proteins score below 1.0: pea ~0.82, rice ~0.59, soy ~1.0 (the plant exception). For vegans, combining sources across the day (legumes + grains, soy + nuts) produces a complete amino acid profile and offsets the digestibility gap by targeting the upper end of intake ranges.
