Custard-apple (Annona squamosa), native to tropical regions of the Americas and Asia, is a nutrient-dense fruit prized for its creamy texture and complex carbohydrate profile. Per 100g, it provides 101 calories with 2.4g of fiber and 25.2g of carbohydrates, delivering sustained energy without rapid blood sugar spikes when consumed whole. The fruit is notable for its potassium content (382mg per 100g), which supports cardiovascular health and blood pressure regulation—critical factors in longevity. Custard-apple contains bioactive polyphenols and acetogenins, compounds with emerging evidence for antioxidant and anti-inflammatory properties. The natural fructose and glucose, combined with adequate fiber, create a favorable glycemic profile compared to refined sugars. Additionally, the fruit provides meaningful amounts of vitamin C (19.2mg), which supports immune function and collagen synthesis, and iron (0.71mg) for oxygen transport. Traditional use in Ayurvedic and Chinese medicine aligns with modern nutritional science showing benefits for digestive health, metabolic function, and cellular protection. The creamy texture and natural sweetness make it an excellent whole-food alternative to processed desserts, supporting adherence to health-promoting eating patterns.
High potassium content (382mg/100g) activates sodium-potassium pumps in blood vessel walls, promoting vasodilation and reducing hypertension risk
Dietary fiber (2.4g/100g) feeds beneficial gut bacteria, increases stool bulk, and supports regular elimination while soluble fiber helps regulate glucose absorption
Contains polyphenols and acetogenins that scavenge free radicals and inhibit pro-inflammatory signaling pathways
Vitamin C (19.2mg/100g) is essential for collagen cross-linking, immune cell proliferation, and antioxidant protection
Contains 0.71mg iron per 100g plus vitamin C, which enhances non-heme iron absorption and supports hemoglobin synthesis
Custard-apple's carbohydrate-fiber ratio makes it ideal for sustained afternoon energy without disrupting evening blood glucose or sleep quality; the potassium supports metabolic activity when circadian cortisol peaks naturally
Breaks a fast
The natural sugars (fructose, glucose) break a fast, making it unsuitable for fasting windows; ideal during eating windows or as a post-workout recovery fruit paired with protein

Custard-Apple scores 66/100 in Formulate, making it a moderate choice. Its strongest contributions come from Vitamin C, Potassium, Vitamin B6. The score blends nutrient density, fiber, healthy fats, protein quality, bioactive compounds, and glycemic impact.
Not particularly. A 140 g serving provides about 2.4 g of protein (~5% of the 50 g daily value).
It's a moderate source of fiber. A 140 g serving provides about 3.4 g of fiber (~12% of the 28 g daily value).
In a 140 g serving, custard-apple is highest in Vitamin C (~30% DV), Potassium (~11% DV), Vitamin B6 (~11% DV), Riboflavin (~11% DV).
Not really. A 140 g serving has about 31.9 g of net carbs (35.3 g total minus 3.4 g fiber).
Best in the midday. Custard-apple's carbohydrate-fiber ratio makes it ideal for sustained afternoon energy without disrupting evening blood glucose or sleep quality; the potassium supports metabolic activity when circadian cortisol peaks naturally
A typical serving is around 140 g (~141 kcal), based on the FDA's Reference Amount Customarily Consumed for this food category. There's no fixed daily target — most adults benefit from rotating custard-apple alongside several other fruit sources.
Custard-Apple pairs nicely with: Pair with Greek yogurt or kefir because the probiotics support gut microbiota diversity while the fruit's natural sugars provide prebiotic substrate for beneficial bacteria growth; Combine with almonds or walnuts because the healthy fats slow sugar absorption, extend satiety, and provide complementary micronutrients (vitamin E, magnesium); Mix with lime juice because citric acid enhances non-heme iron absorption and the vitamin C content amplifies antioxidant bioavailability; Serve with leafy greens (spinach, kale) in smoothies because the fiber combination improves nutrient density and sustained energy release.
