Low-sugar fruits are typically berries and certain citrus and avocado, with the absolute lowest sugar per serving being avocado (about 1 g per whole fruit) and berries like raspberries, blackberries, and strawberries also very low (roughly 4–7 g per cup or per fruit, depending on variety). If you’re aiming to minimize sugar intake from fruit, these are the top choices to consider. Key options

• Avocado: about 1 g sugar per whole fruit; high in healthy fats, very satiating.
• Raspberries: around 5 g sugar per cup; high in fiber.
• Blackberries: around 7 g sugar per cup; also high in fiber and antioxidants.
• Strawberries: roughly 7 g sugar per cup; vitamin C rich.
• Lemons and limes: very low sugar, typically used in flavoring rather than eaten as a primary fruit.
• Grapefruit: about 7–11 g sugar per half grapefruit, depending on size; still relatively low.

Notes for practical choices

• Serving size matters: fruit sugar is per serving, so smaller portions reduce total sugar.
• Pairing with protein or fat (e.g., berries with yogurt or nuts) can blunt glucose response.
• If managing diabetes or strict sugar intake, focus on berries and citrus halves rather than sweeter fruits like mango, grapes, or bananas.

If you’d like, share any dietary goals (e.g., per-serving sugar target, total daily fruit intake, or preference for fresh vs. frozen), and the answer can be tailored with exact options and portion sizes.
