Gooseberries are a tart, summer fruit that often gets overlooked in potassium tracking. A 100 g serving of raw gooseberries supplies about 198 mg of potassium, or roughly 4% of the 4,700 mg Daily Value. But because we tend to eat them by the cup, handful, or berry count rather than on a kitchen scale, it can be tricky to know exactly how much potassium a serving actually provides.
This calculator does the unit math for you. Enter the amount of gooseberries you plan to eat, choose grams, ounces, cups, or individual berries, and the tool converts your portion to grams, estimates potassium, and calculates the percentage of the Daily Value. You can also adjust the potassium-per-100 g value and the daily target if you are using a different reference or following a personalized limit.
Use it for meal planning, sports nutrition, diet tracking, or simply to compare gooseberries with other potassium-rich produce. The result area even shows the step-by-step conversion so you can see how the number was built.
Raw gooseberry reference: 198 mg potassium per 100 g. Cup weight ≈ 150 g; one berry ≈ 6 g.
How It Works
Potassium in fruit is not evenly distributed by volume, but it is very consistent by weight. This means potassium content scales linearly with the amount of gooseberry you eat.
Potassium (mg) = serving weight (g) × (potassium per 100 g ÷ 100)
The calculator uses 198 mg per 100 g as the reference for raw gooseberries, the value published by USDA FoodData Central. If you prefer a different value, perhaps because you are using a local nutrition database or a specific cultivar, enter it in the potassium per 100 g field and the result updates.
For unit conversions, 1 cup of whole gooseberries is treated as 150 g and one average berry as 6 g. These are typical values, not the exact weight of every berry, so they are close enough for most nutrition tracking.
Worked Examples
Example 1: 100 g bowl. 100 × 198 ÷ 100 = 198 mg, which is 4.2% of the 4,700 mg Daily Value.
Example 2: 1 cup. One cup is about 150 g, so 150 × 198 ÷ 100 = 297 mg, or 6.3% of the Daily Value.
Example 3: 8 berries. At 6 g each, 8 berries weigh about 48 g. 48 × 198 ÷ 100 = 95 mg, about 2.0% of the Daily Value.
Potassium Reference Table
The table below compares raw gooseberries with a few common potassium sources. Percentages use the adult Daily Value of 4,700 mg.
| Food (raw) | Potassium per 100 g | % DV |
|---|---|---|
| Gooseberries | 198 mg | 4.2% |
| Bananas | 358 mg | 7.6% |
| Cantaloupe | 267 mg | 5.7% |
| Tomatoes | 237 mg | 5.0% |
| Oranges | 181 mg | 3.9% |
| Apples | 107 mg | 2.3% |
Values are rounded, common USDA reference figures. Actual numbers vary with ripeness, variety, and growing conditions.
Why Track Gooseberry Potassium?
Potassium is an electrolyte that supports nerve signaling, muscle contraction, and fluid balance. Many people fall short of the recommended 4,700 mg per day, so high-potassium fruits are useful additions to a balanced diet.
Athletes who lose potassium through sweat, people monitoring blood pressure, and anyone doing structured meal planning can use this number to build a day that meets their target. Gooseberries are not the highest-potassium fruit, but they are a useful, low-calorie source with fiber and vitamin C.
If you have kidney disease or take medications that affect potassium, talk to a doctor or renal dietitian before increasing or restricting potassium-rich foods. Serving size matters because even moderate sources add up.
If you also want the vitamin C story from the same gooseberry serving, run the numbers through the gooseberry vitamin C calculator.
Common Mistakes to Avoid
- Using dried or canned values. Drying removes water and concentrates nutrients, so dried gooseberries have more potassium per 100 g than fresh fruit. Canned fruit is often drained and may have a different weight-to-potassium ratio.
- Assuming every berry weighs 6 g. Large cultivated berries can weigh more than this; small wild gooseberries weigh less. If precision matters, weigh the entire serving instead of counting individual berries.
- Forgetting the unit conversion. Cups are not a weight. This calculator always converts to grams first, which avoids the cup-of-gooseberries ambiguity.
- Comparing percentage with an old Daily Value. Current Nutrition Facts labels use 4,700 mg for potassium. If you are looking at older labels or another country's database, the target can differ.
Frequently Asked Questions
Can I use this calculator for cooked or canned gooseberries?
The default value is for raw gooseberries. Boiling can leach some potassium into cooking water, and canned fruit may be packed in syrup that changes the weight and nutrient density per 100 g. If you have package data, enter its potassium-per-100 g value instead.
Why do different websites list different potassium numbers?
Variety, ripeness, soil potassium, and moisture content all cause small variations. Many databases report 198 mg per 100 g for raw gooseberries, but a range of 160 to 230 mg is not unusual across cultivars and analysis methods.
Is a gooseberry a high-potassium food?
It is a moderate source. At about 198 mg per 100 g it sits near apples, pears, and grapes, and well below bananas, sweet potatoes, and leafy greens. For most people, that makes it easy to fit into a potassium-balanced meal plan.
Can gooseberries count toward my daily potassium goal?
Yes. A one-cup serving provides roughly 297 mg, or about 6% of the Daily Value. Several such servings throughout the day from different fruits and vegetables can make a meaningful contribution.
