Are butter tarts healthy?
Not really. Butter tarts get grade E on the open 2023 Nutri-Score algorithm, the lowest of five — a sometimes food rather than an everyday one.
Against
- Sugar: 24 g per serving. For scale, the WHO's ideal limit for free sugars (added sugar, plus the sugar in honey, syrups and juice) is 25 g a day.
- Saturated fat: 8.8 g per serving — 44% of the 20 g daily reference intake.
A typical serving (one, 85 g) has 390 kcal, 3.8 g protein, 22 g fat and 45 g carbs. Other weights in the table.
A healthier swap at the same calories: almonds (70 g): −21 g sugar, −6.2 g saturated fat.
How we judge this, and the sources
The answer comes from the food's composition, not from opinion: its Nutri-Score grade on the open 2023 algorithm, a traffic light for sugar, salt, saturated fat and fiber per 100 g, and the share of daily reference amounts in a typical serving (for salt, sugar, fiber and vegetables, those of the WHO). It rates the food's nutrient profile; it is not medical advice. Formulas, thresholds and every source are on the methodology page; last checked against the sources on September 30, 2026. The short food description was written by our language model (AI) — how we check the text.
A butter tart is a small Canadian pastry shell filled with butter, sugar, syrup and egg, often with raisins, baked until the filling is semi-firm.

How much movement is one serving?
A serving (one, 85 g) is 390 kcal — roughly 2 h 07 min of easy walking or 49 min of cycling for a 70 kg (154 lb) person. In the diary, minutes are worked out for your weight and the activities you actually do.
Healthier swaps for Butter Tarts
Why swap: butter tarts have a lot of sugar (28 g per 100 g), a lot of saturated fat (10 g per 100 g), a fair amount of salt (0.8 g per 100 g), almost no fiber (1.3 g per 100 g). The swaps below fix that at the same calories.
How we pick
A swap is offered only for a real problem with the food (for grades C–E an amber traffic light counts too), from the same or a neighbouring category, in a serving matched to the same calories (±25%; drinks glass for glass) and no more than one and a half times the original weight, a full Nutri-Score grade better and with a noticeable gain per serving. We don't suggest “salad instead of pizza”.
- Almonds — 70 g, 405 kcal: −21 g sugar, −6.2 g saturated fat.
