How to Measure Your 30-Gram Walnut Serving
For many, a 30-gram serving is a standard daily intake, offering a powerhouse of nutrients without excessive calories. While weighing is the most accurate method, it isn't always practical. Fortunately, there are easy, visual ways to approximate this portion. The key difference lies in whether you are counting whole nuts or halves.
The Answer in Kernels and Halves
To achieve a 30-gram serving, you'll need:
- Approximately 14 walnut halves: This is a widely cited measure for a 30-gram or one-ounce portion.
- About 10 whole walnuts: For those using whole shelled nuts, a serving is a slightly lower number due to size variations.
- A small handful: If counting isn't an option, a small, cupped handful is a good, rough estimate for a 30-gram serving.
