Peach and blueberry crisp¶
Fruit crisps are often made with oats and nuts, which add phosphorus and potassium. This topping is just flour, brown sugar, butter and cinnamon. Half a cup of canned peaches in juice has about 160 mg potassium, against about 285 mg in a medium fresh peach, and draining off the juice removes some more.

Carbohydrate per serving
29 g carbohydrate (about 2 carb choices of 15 g). It is a dessert, so count it with the meal or as a snack, the way your diabetes plan says.
Per serving¶
| Energy | Carb | Protein | Potassium | Phosphorus | Sodium | Fluid | Fiber |
|---|---|---|---|---|---|---|---|
| 189 kcal | 29 g | 1.9 g | 152 mg | 31 mg | 7 mg | none | 2.2 g |
Checked by scripts/build_handbook.py: sodium at most 140 mg per serving; "lower potassium" means at most 200 mg and "lower phosphorus" at most 100 mg per serving. See how recipes are checked.
Ingredients that are not in the app's food list (herbs, spices and a few others) add about 2 mg potassium per serving; they are counted above.
Ingredients¶
| Ingredient | Amount | Grams |
|---|---|---|
| Peaches, canned in juice | 2 cups canned peaches in juice, drained (one 29-oz can) | 496 g |
| Blueberries, raw | 1 cup blueberries, fresh or frozen | 148 g |
| Cornstarch | 1 tbsp cornstarch | 8.0 g |
| Lemon juice, fresh | 1 tbsp lemon juice | 15 g |
| Cinnamon, ground | 1 tsp ground cinnamon | 2.6 g |
| Flour, all-purpose | ½ cup all-purpose flour | 62 g |
| Sugar, brown | 3 tbsp packed brown sugar | 41 g |
| Butter, unsalted | 4 tbsp unsalted butter, cold, in small pieces | 57 g |
Steps¶
- Heat the oven to 375 °F (190 °C). Drain the peaches well and cut them into bite-size pieces.
- Toss the peaches and blueberries with the cornstarch, lemon juice and half the cinnamon in a small baking dish.
- Rub the flour, brown sugar, butter and the rest of the cinnamon together with your fingertips until it looks like coarse crumbs. Scatter over the fruit.
- Bake for 30–35 minutes, until the topping is golden and the fruit bubbles. Cool for 10 minutes and cut into 6 portions.
Why it works for kidneys¶
- The numbers count the peaches with their juice, so draining them makes the real potassium a little lower than shown.
- No oats, nuts or baking powder means very little phosphorus: about 30 mg a serving.
- NKF advises not drinking the liquid from canned fruit, because it holds some of the potassium.
Make it fit you¶
- Other fruit: canned pears in juice or fresh apples, peeled and sliced; check the carbohydrate.
- Freeze: freeze single portions, then warm in the microwave.
- Less carbohydrate: use 2 tablespoons of brown sugar in the topping.
