WHY TO LIMIT IT ON KETO
- Moderate-to-high sugars: ~11.7g net carbs/100g strains strict keto limits
- Glycemic impact: fructose + glucose raise carb load despite low fat
- Portion caution: keep to 2–3 oz (56–85g) max if included
- Best for CKD/TKD: fits better on cyclical or targeted keto days
- Use as an accent: a few chunks or 1–2 tbsp juice to flavor dishes/drinks
- Lower-carb fruit alternatives exist (e.g., strawberry)
HEALTH BENEFITS
- Excellent vitamin C source supporting immune and antioxidant defense
- Provides bromelain (protease) which may aid protein digestion
- Bromelain and vitamin C may support post-exercise recovery
- Good source of manganese for bone health and metabolism
- Contains B vitamins (incl. B6) for neurotransmitter synthesis
- Hydrating, with small amounts of polyphenols and carotenoids
PREPARATION SUGGESTIONS
MICRO PORTIONS
Measure 2–3 oz fresh pineapple and log 7–10g net carbs; enjoy as a rare treat.
GRILLED TOPPING
Grill a few small chunks to top pork-chops or ham; keep fruit minimal per serving.
DIGESTIVE AID
Have a tiny portion after a protein-heavy meal to leverage bromelain for digestion.
JUICE CONCENTRATE
Stir 1–2 tbsp fresh juice into sparkling-water or iced green-tea for flavor with fewer carbs.
STIR-FRY ACCENT
Add 1–2 oz at the end of cooking with shrimp, tamari, and low-carb veg to keep carbs down.
SPECIAL OCCASION TREAT
Reserve for cyclical carb days or events; pre-portion to avoid mindless snacking.
